    - funny look to tab with bottom alignment When a tab page is made with the tabs aligned at the bottom instead of the default top one gets a funny look and feel. The rounded parts of the tabs continues to be at the top and the square end is at the bottom. One would expect it to be inverted. (This is .NET 2.0 framework and I cannot move to new frameworks due to certain other problems) Is something wrong here ? Anonymous Tag: IBindingList Filter and DataGridView Tag: 117433

    - Databinding problem - DisplayName empty I'm having some trouble getting databinding to a ListBox to work correctly. I think the collection I'm trying to bind against is a little odd, so I'm wondering if that could be part of the problem. Below is a sample of the databinding code. AxisCollection axis = GetAxisCollection() myListBox.DataSource = null; myListBox.Items.Clear(); myListBox.DisplayMember = "Attribute.Name"; myListBox.ValueMember = "Attribute.AttributeID"; myListBox.DataSource = attribs; AxisCollection is a collection which derives from List<Axis>. The Axis class looks something like: Attributes Name AttributeID DisplayNumber Attributes is a reference type property for the Axis class. After setting the DataSource property, I notice (using the debugger) that the DisplayMember property changes to an empty string. When I look at the displayed values in the listbox, they are just the name of the class (repeated for each element in the collection). Interestingly, if I change the myListBox.DisplayName to a value type (i.e. "DisplayNumber") on the class, the value is displayed correctly in the ListBox and the DisplayName remains after setting the DataSource. Any ideas on what could be going on would be greatly appreciated. Thanks! Tag: IBindingList Filter and DataGridView Tag: 117425

    - TooStripComboBox.Validate event: setting Cancel = true doesn't prevent other toolbar controls from being clicked I have a toolbar with a buncha buttons and a combo box. When the program starts, the combo opens and its mandatory that the user make a selection before continuing. I'm trying to do this with the Validate event, but its not working. If the combo is open and the user clicks a different toolbar button, my code sets Cancel = true and maintains focus on the combo box, but the Click event of the other button still gets executed. The result is not at all what I'm looking for! How can I prevent the other buttons from being clicked? Tag: IBindingList Filter and DataGridView Tag: 117424

    - Form created on BackGroundThread Hi, I have some generic module that handles exceptions. simply you call it like this: "LogManager.ErrorMessage(ex)". Worked great, until we now discovered that it isn't Thread-safe. What actially happens is this: A Form is made, labels and buttons are made etc with the exception-details, but when trying to show the Form (MyExceptionForm.ShowDialog) we get an System.Security.SecurityException (see udnerneath for more info). Seems completely normal to me, because we are accessing the UI from another Thread. But how to find a solution? Thanks a lot in advance, Pieter PS 1 : I see 2 possiblities: 1. Call InvokeRequired with Invoke like we usally do when accessing controls from another thread (http://msdn.microsoft.com/en-us/library/ms171728(VS.80).aspx). BUT: MyExceptionForm.InvokeRequired returns false... I guess this is because it has been constructed in a background Thread? 2. To get around this problem: Figure out when we are on a background thread (via Threading.Thread.CurrentThread.IsBackground: is this true??) and than get via an event an an Invoke or something like that on the Main-htread and call the form from there? 3. ... PS 2: The exception when doing a MyExceptionForm.ShowDialog: System.Security.SecurityException was caught Message="Request for the permission of type 'System.Security.Permissions.UIPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."

    - deadlock when using waitOne in a STA thread Hi, I have the problem described bellow with the calls to WaitHandle.WaitOne causing re-entrancy on main GUI thread (STA) of a .NET application and I would like to find out: - did anybody else run into the same problem? - is it a known issue? is there a fix for it? - is there a workaround for it? - if no fix/workaround I would like to find out the complete list of messages that are being handled (dispatched by ole32.dll OLE/COM message pump) when doing WaitOne on a STA thread. The problem is: I have 2 (or more) calls pending to execute on the main gui thread (I am actually doing Invoke on some control) the first call, at some point does WaitHandle.WaitOne. at this point, if a Windows message comes to the app (like WM_POPUPSYSTEMMENU - 0x0313 ) triggered by a right-click on the task bar icon of the app the following happens: - the app processes this message - the app starts processing other pending messages - like my second invoke - at this point my app is deadlocked, because it is not supposed to enter the second call before finishing processing the first one. - also at this point the entire system is not behaving properly - for example I cannot bring up any window by clicking on the taskbar icon important note: if I would not do right click on the taskbar icon of my app, and just let it work in background, everything would be ok. After investigating this issue for a while, I found that WaitOne is not actually a blocking call when called from an STA thread. The only reference I found related to this matter in MSDN pages is here: http://msdn.microsoft.com/en-us/library/74169f59.aspx . Quoting from that page: "WaitHandle..::.WaitOne,WaitHandle..::.WaitAny, WaitHandle..::.WaitAll, Monitor..::.Enter, Monitor..::.TryEnter, Thread..::.Join, GC..::.WaitForPendingFinalizers, and so on are all responsive to Thread..::.Interrupt and to Thread..::.Abort. Also, if your thread is in a single-threaded apartment, all these managed blocking operations will correctly pump messages in your apartment while your thread is blocked." If the apartment state is STA this function actually creates a message loop that is processing some events (for now I have been able to identify 2 of them (WM_POPUPSYSTEMMENU and WM_ACTIVATEAPP). The problem is that these messages triggers processing of other messages in the queue (like the registered messages used for invoke in .NET ). I have attached a simplified application to demonstrate the issue. In this app I have created a thread from where I am calling multiple times the same function which is suppose to execute on the GUI thread. I have put some console prints to show that it is executing another invoke on the main thread even if it is supposed to stay in the wait. Another thing, in my app the calls to some functions are not supposed to re-enter (and we are protecting them with the waitOnes) but if I modified the sample app (attached to this mail) to have a non-blocking re-entrancy , I noticed if I right click on the taskbar icon while the first call is in waitOne, all the other calls will be executed before the first call ends - this is actually easy to explain since the other calls are not processed by the app message loop but they are processed by the message loop created by the WaitOne. however I don't think this should be the normal behavior - that is: when I invoke 3 calls on some thread, the order of execution should be the order of the invokes. waiting forward for your replies Daniel. begin 666 DeadLockWaitOne.zip M4$L#!!0````(`&-ONSA2]6S&:0,``"@)```F````1&5A9$QO8VM786ET3VYE M+T1E861,;V-K5V%I=$]N92YC<W!R;VJ]5LUNVS@0OA?H.W"-`FF!6C*2;..T ML@#_)0W0;@([:?:0"R6.;+;\`TDUT6[WR?:PC[2OL*1,N5:<I+YL#X'#^3[.

    - ProgressBar and Form loading Hello, I don't know if such question was already posted but I didn't find anything through different posts. I have the Main MDI window with a StatusBar. Inside my StatusBar there is a ProgressBar. When I click on the menu in my MDI Parent, a child form is loaded. I would like to know if there is a way to increment a progressbar value while child form is loading ? I tried to use background worker but i had some cross thread access exceptions. any ideas ?

Because we have still .NET 1.1 clients around, we made a small ASP.NET startup application that checks host header values and redirects (Response.Redirect(...)) to the .application file in case the client has .NET 2.0 installed. Otherwise it will launch the old smart client on a web page. This all works fine as long as we start the ASP.NET startup page (let's call it StartClient.aspx) from within Internet Explorer. If we put a link to the startup page into an e-mail or just on the desktop launching the ClickOnce client with this link fails with a "Cannot Start Application" message box. The details say: SOURCES Deployment url : https://myserver/Client/StartClient.aspx ERROR SUMMARY Below is a summary of the errors, details of these errors are listed later in the log. * Activation of https://myserver/Client/StartClient.aspx resulted in exception. Following failure messages were detected: + Downloading https://myserver/Client/StartClient.aspx did not succeed. + The remote server returned an error: (403) Forbidden. The deployment url is the startup page and not the .application manifest file as we would expect. When checking IIS logs, we can find first a request to StartClient.aspx, second a request to https://myserver/ClickOnceClient/MyApp.application (the manifest), and a third request back to StartClient.aspx. This third request doesn't happen when we access the aspx page from within Internet Explorer (where, as mentioned before, everything works as expected). It seems like it only partially redirects when launching from a hyperlink in a document. Thanks for your help in advance, Jürgen Tag: IBindingList Filter and DataGridView Tag: 117413

    - Checking whether or not checkbox on web page is checked Let's say that I use the following code to get a reference to a checkbox on a web page in a WebBrowser control: Dim oHtmlElement As HtmlElement oHtmlElement = WebBrowser1.Document.GetElementById("chkThrowInTheTowel") How can I tell if the checkbox is checked or not? oHtmlElement.Checked is not an option, so how would I do this?

    - Binding DataGridView after Filtering Hi, I have no idea why the datagrid does not display correct information. I have a load button which loads all data based on query (i have observed 100), then I have a textbox and a button to passing in filter and it displays appropriate records. Now if i click the load button again, it does not load all data but shows only the filtered data that was used during filtering process. I am attaching the sample code. Please help, Stephen private void btn_Load_Click(object sender, EventArgs e) <--- loading all records { DataSet _dsEmployees = returnDataset(); _dsEmployees = returnDataset(); myGridView.DataSource = _dsEmployees.Tables[0]; } private DataSet returnDataset() <--- this does work { dsEmployees = (DataSet)CacheKeys.Cache[CacheKeys.EmployeeDS]; if (dsEmployees == null) { dsEmployees = OracleDataRetrieval.GetEmployeeDataSet(GetSQL()); CacheKeys.Cache.Insert(CacheKeys.EmployeeDS, dsEmployees, null, DateTime.Now.AddMinutes(5), System.Web.Caching.Cache.NoSlidingExpiration); } return dsEmployees; } private void btn_Filter_Click(object sender, EventArgs e) <-- filtering data { string filterSQL = txt_Filter.Text.Trim(); DataSet _dsEmployee = returnDataset(); DataView _dvEmployee = _dsEmployee.Tables[0].DefaultView; _dvEmployee.AllowNew = false; _dvEmployee.AllowDelete = true; _dvEmployee.Sort = "FIRST_NAME ASC, LAST_NAME ASC"; _dvEmployee.RowFilter = "LAST_NAME LIKE '" + filterSQL + "*'"; if (_dvEmployee.Count != 0) myGridView.DataSource = _dvEmployee; } Tag: IBindingList Filter and DataGridView Tag: 117404

    - Custom DataGridView and keyboard input - C# VS2005 Hello, I work in VS2005 in C#. I have a problem with my custom DataGridView and keyboard input. I am trying to catch user input and search through current column. Everything works fine with searching. The problem is when I press one of non-english letters or number from numeric keyboard I do not get character that I pressed. For example: I press key with code 0x010D but catch it as 0x00BA. One good example: when I press 'e' or 'E' (Shift+e) I get inputChat = 'E', msg.WParam = 0x45, msg.LParam = 0x120001 This is the method where I do that: protected override bool ProcessCmdKey(ref Message msg, Keys keyData) { char inputChar = (char)((ushort)msg.WParam.ToInt32()); // msg.WParam is 0x00BA but it should be 0x010D // msg.LParam is 0x270001 ... } Here are the questions: 1. Is there a way to extract the correct code for the pressed key from msg parameter and its properties? 2. Is there a better place (method) to catch a keyboard input? I would appreciate any suggestion, Vlado P.S. When I catch keyboard input in one of my other custom controls I use ProcessKeyPreview and everything works fine, but ProcessKeyPreview is not good in DataGridView.

    - deadlock when using waitOne in a STA thread Hi, I have the problem described bellow with the calls to WaitHandle.WaitOne causing re-entrancy on main GUI thread (STA) of a .NET application and I would like to find out: - did anybody else run into the same problem? - is it a known issue? is there a fix for it? - is there a workaround for it? - if no fix/workaround I would like to find out the complete list of messages that are being handled (dispatched by ole32.dll OLE/COM message pump) when doing WaitOne on a STA thread. The problem is: I have 2 (or more) calls pending to execute on the main gui thread (I am actually doing Invoke on some control) the first call, at some point does WaitHandle.WaitOne. at this point, if a Windows message comes to the app (like WM_POPUPSYSTEMMENU - 0x0313 ) triggered by a right-click on the task bar icon of the app the following happens: - the app processes this message - the app starts processing other pending messages - like my second invoke - at this point my app is deadlocked, because it is not supposed to enter the second call before finishing processing the first one. - also at this point the entire system is not behaving properly - for example I cannot bring up any window by clicking on the taskbar icon important note: if I would not do right click on the taskbar icon of my app, and just let it work in background, everything would be ok. After investigating this issue for a while, I found that WaitOne is not actually a blocking call when called from an STA thread. The only reference I found related to this matter in MSDN pages is here: http://msdn.microsoft.com/en-us/library/74169f59.aspx . Quoting from that page: "WaitHandle..::.WaitOne,WaitHandle..::.WaitAny, WaitHandle..::.WaitAll, Monitor..::.Enter, Monitor..::.TryEnter, Thread..::.Join, GC..::.WaitForPendingFinalizers, and so on are all responsive to Thread..::.Interrupt and to Thread..::.Abort. Also, if your thread is in a single-threaded apartment, all these managed blocking operations will correctly pump messages in your apartment while your thread is blocked." If the apartment state is STA this function actually creates a message loop that is processing some events (for now I have been able to identify 2 of them (WM_POPUPSYSTEMMENU and WM_ACTIVATEAPP). The problem is that these messages triggers processing of other messages in the queue (like the registered messages used for invoke in .NET ). I have attached a simplified application to demonstrate the issue. In this app I have created a thread from where I am calling multiple times the same function which is suppose to execute on the GUI thread. I have put some console prints to show that it is executing another invoke on the main thread even if it is supposed to stay in the wait. Another thing, in my app the calls to some functions are not supposed to re-enter (and we are protecting them with the waitOnes) but if I modified the sample app (attached to this mail) to have a non-blocking re-entrancy , I noticed if I right click on the taskbar icon while the first call is in waitOne, all the other calls will be executed before the first call ends - this is actually easy to explain since the other calls are not processed by the app message loop but they are processed by the message loop created by the WaitOne. however I don't think this should be the normal behavior - that is: when I invoke 3 calls on some thread, the order of execution should be the order of the invokes. waiting forward for your replies Daniel. begin 666 DeadLockWaitOne.zip M4$L#!!0````(`&-ONSA2]6S&:0,``"@)```F````1&5A9$QO8VM786ET3VYE M+T1E861,;V-K5V%I=$]N92YC<W!R;VJ]5LUNVS@0OA?H.W"-`FF!6C*2;..T ML@#_)0W0;@([:?:0"R6.;+;\`TDUT6[WR?:PC[2OL*1,N5:<I+YL#X'#^3[.

I tried the following: Dim oHtmlElement As HtmlElement oHtmlElement = WebBrowser1.Document.GetElementById("cboGroups") oHtmlElement.InnerText = "Group 1" but that doesn't work, even though "Group 1" is one of the options in the dropdown.

    - Memory leak with TextBox? I have a windows app which contains a readonly multi-line textbox. This textbox is used to display "log" information as actions/events occur within the application. The contents can eventually get to be very large, as our app is often left to run overnight. We allow the user to clear the contents of the textbox by right-clicking and selecting "Clear" from a context menu. Within the event handler for this menu item, I've tried clearing out the contents using the Clear( ) method and by setting Text to "". Regardless of how I clear it, when I monitor memory usage I notice that the memory actually goes up after the contents are cleared. For example, in one particular test I let the app run overnight. The next morning I cleared it, and mem usage actually went up over 200 megabytes. I waited for a long time to see if GarbageCollection would eventually release it, and it did not. I've tried other things within my code as well such as calling ClearUndo immediately afterward. I also tried forcing garbage collection afterward. No luck. This is a problem for us because our users need to see this log information, but yet it can get very big and they need the ability to occasionally clear it. Any ideas why clearing out a textbox causes memory usage to go up? Is this an acknowledged memory leak within the .Net framework of which I'm just not aware?

    - RichTextBox.RTF handle Hello, I have some problem with handling the RTF type string. I have an application which must have a text box, can handle Pictures and formatting texts, etc. So I have chosen the RichTextBox control and stored the RTF property as nvarchar in my database. It works fine, but now I have to show this text in a browser and I can't convert the RTF string to HTML. And I can't get the images from the RTF string. So the question is: How can I convert the RTF string to HTML or any other form which contains images, formatted strings, tables, etc. Or which control should I use to get these features.

I've found out how to generate the file without problems, but I cannot seem to make it save the file to a predetermined location. Is such a thing even possible? The code I use to generate and open the file is below private void CreateResponse(string QueryName, string CSVContent) { System.Text.Encoding encoding = System.Text.Encoding.GetEncoding("ISO-8859-15"); byte[] b = encoding.GetBytes(CSVContent); Response.Clear(); Response.Buffer = true; Response.AddHeader("Content-Type", "application/ms-excel"); Response.ContentType = "text/csv"; Response.AddHeader("Content-Disposition", "attachment;filename=" + DateTime.Now.ToString("dd-MM-yyyy") + "-" + QueryName + ".txt"); Response.BinaryWrite(b); Response.End(); } can somebody please help me figure out how I have to modify it in order to make it save instead of just trying to open the file?

    - Expired certificates in the clickonce manifest When a certificate expires, what options are available? - use an internal certificate authority where you can renew a certificate with the same private key - delete the clickonce cache from each computer - any others? Background: The ClickOnce technology requires every application update to be signed using the same private key. When a certificate expires most CAs like Verisign and Comodo will generate a new private key with the renewed certificate. ClickOnce will throw up an error when this occurs and will not download the update. http://groups.google.com/group/microsoft.public.dotnet.framework.windowsforms/browse_thread/thread/64a15850347c32df/3b85d27a8b28c451?lnk=st&q=certificate+clickonce+linda+liu+expired Thanks, Brian Tag: IBindingList Filter and DataGridView Tag: 117350

    - PostScript font support in GDI+? Is support for PostScript fonts planned, or possible through a workaround? Only TrueType fonts and OpenType fonts containing TrueType outlines can be picked for WinForms forms and controls; Type 1 and OpenType with Postscript outlines don't show up in the font selector. I'm working on a kiosk app for which part of the layout (background etc.) was designed by a graphic agency, who used a font from Adobe for textual elements. Now I'm expected to use the same font in software, but it's only available in PS and OpenType-PS. I did find a close look-alike in TTF format at URW++, but even I (not a graphic designer by art&heart) found some small differences, and I'd like to have the exact same typeface. There are tools that convert PS to TT outlines, but the results look so bad (choppy, pixelated) that they're useless for all but very large font sizes. Funny though: those PS-to-TTF converted fonts look just perfect under Linux, it's only under Windows that they get that choppy look.

    - Datagridview conditional formatting using separate column Hi, I want to conditionally format a column in a datagridview according to the value in a different of my datasource. So if col 1 is true, then display col 2 in a different colour. I know that I can use the cell formatting event if I want to conditionally format the cell according to the value in that same column but is that the best method to use if I'm using a different column for the condition? Is this the best way of doing it, or is there something better? In cell formatting event... if dg.columns(e.columnindex).datapropertyname="ConditionColumn" then if e.value=conditionvalue then dim cell as datagridviewcell=dg(hard-coded column number, e.rowindex) cell.style.... do whatever formatting required end if end if Would be a bit of a kludge having to hard code the 'target' column number but I would actually replace that with a find on the datacolumns of the grid. In my case, I don't actually need the column that is being looked at for the condition on the grid. Does it HAVE to be there? Problem there is that if I add it and make it invisible then the formatting event doesn't kick in. Tag: IBindingList Filter and DataGridView Tag: 117339

    - Problems hosting a custom control / cell / column in a DataGridVie I'm having trouble hosting a custom control in one of the columns of a DataGridView object. The custom control is a multi-column combo box, which behaves almost identical to ComboBox, except that it shows multiple data columns when dropping down, similar to old MS Access style combos. The MultiColumnComboBox control can be found here: http://www.edneeis.com/control.aspx?ID=7 Based on the info in this article (http://msdn.microsoft.com/en-us/library/7tas5c80.aspx), and a little experimenting, I have it basically working. The control is being shown as a combo box in the data grid, it is being bound correctly, and is displaying properly. To get that far, I had to create a a hosting DataGridViewEditingControl control (implementing the IDataGridViewEditingControl interface), a DataGridViewComboBoxCell cell, and a DataGridViewComboBoxColumn specific to the new control. The one issue I'm having is with the drop-down event. I keep getting the following exception: Object reference not set to an instance of an object at System.Windows.Forms.DataGridViewComboBoxCell.ComboBox_DropDown(Object sender, EventArgs e) at System.Windows.Forms.ComboBox.OnDropDown(EventArgs e) at System.Windows.Forms.ComboBox.WmReflectCommand(Message& m) at System.Windows.Forms.ComboBox.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.UnsafeNativeMethods.SendMessage(HandleRef hWnd, Int32 msg, IntPtr wParam, IntPtr lParam) at System.Windows.Forms.Control.SendMessage(Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.Control.ReflectMessageInternal(IntPtr hWnd, Message& m) at System.Windows.Forms.Control.WmCommand(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ScrollableControl.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.UnsafeNativeMethods.CallWindowProc(IntPtr wndProc, IntPtr hWnd, Int32 msg, IntPtr wParam, IntPtr lParam) at System.Windows.Forms.NativeWindow.DefWndProc(Message& m) at System.Windows.Forms.Control.DefWndProc(Message& m) at System.Windows.Forms.Control.WmMouseDown(Message& m, MouseButtons button, Int32 clicks) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ComboBox.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.UnsafeNativeMethods.DispatchMessageW(MSG& msg) at System.Windows.Forms.Application.ComponentManager.System.Windows.Forms.UnsafeNativeMethods.IMsoComponentManager.FPushMessageLoop(Int32 dwComponentID, Int32 reason, Int32 pvLoopData) at System.Windows.Forms.Application.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.Run(Form mainForm) at WindowsApplication2.Program.Main() in C:\Documents and Settings\jarmstrong\My Documents\Visual Studio 2005\Projects\Solution1\WindowsApplication2\Program.cs:line 17 at System.AppDomain._nExecuteAssembly(Assembly assembly, String[] args) at System.AppDomain.ExecuteAssembly(String assemblyFile, Evidence assemblySecurity, String[] args) at Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly() at System.Threading.ThreadHelper.ThreadStart_Context(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart() DataGridViewComboBoxCell.ComboBox_DropDown is hidden from me, so I'm not sure what's going on.

    - DataGridView bound to BindingList<myObj> -- how to update immediately when they click a checkbox? I have a DataGridView bound to a BindingList<myObj>. In my DGV I have two checkbox columns. Right now, the user can check these, and if he clicks on another row or clicks on one of the buttons of the form, it will fire the EndEdit event, in which I have embedded a Save(). Is there a way to get it to save when they click on it, rather than waiting for the row to lose focus? I'm also going to have to make one of the textbox columns editable, so will the same solution work for that case as well? Thanks, RobinS.

    - Automating interactions with a web site Consider the following scenario: 1) User goes to a web site (.aspx page) and logs in 2) User enters various values in controls, clicking on NEXT buttons to go to a sequence of pages, until they get to a page that displays, among other things, a table showing 10 rows, each with a checkbox at the far left (i.e. first column). In addition, at the bottom of the table, there are little "links" that can be clicked on to go to the next/prior page, showing the next/prior ten results in a table. Lastly, in case it helps, there is, to the right of the "links", a text box in which the user can type a specific "page" of results to go to. NOTE: Unfortunately, the little "links", and Go To text box, slightly move from page to page, making mouse movement/click recording/playback not a viable option. 3) User puts check mark in all ten checkboxes, then clicks on link to go to next page of results. 4) After user has clicked on a total of 1,000 checkboxes (i.e. 100 pages' worth), they are done (for purposes of this discussion). What I want to do is automate Step 3 above 100 times. So, what I'm imagining is having a Windows form, with a web browser control on it that brings the user to the initial website. Then, the user would do stuff outlined in Step 2. Lastly, there'd be a button on the form (below the web browser control somewhere) that the user could click on to perform Step 3 100 times. Then, the user could just interact with the web browser again, clicking on whatever they need to click on. Is there a way to do something like this?

    - Question about Help Files/systems My boss has asked me to look into the possibility of creating one central help system that can be used by both the windows and web apps on our intranet. (Assume for now that all the applications are written in Dot Net 2.0 and the only db server available is SQL Server 2000.) It stands to reason that simply downloading an entire chm file everytime a web app needs help sounds rather inefficient. What are my options? Suggestions anyone? (Don't want to reinvent the wheel.)

    - RichTextBox very slow I'm using a RichTextBox in a protocol analyser I'm developing. However as the amount of data gets large, e.g. 500000 lines, the control becomes very slow. For example if I load in a saved file it can take 30 seconds just to transfer data from a StringBuilder to the RichTextBox, even with updates turned off with WM_SETREDRAW. Also I highlight a line when the users clicks on it and this can be slow, as can be highlighting all instances of a string match. Is there any way to make actions like adding text to a RichTextBox or highlighted portions of text any faster? TIA, KK Tag: IBindingList Filter and DataGridView Tag: 117325

    - Application Settings and Form Location & Size I'm trying to use Application Settings with From Location & Size. I have created the property binding from the Designer in Visual Studio. ClientSize = MainFormClientSize Location = MainFormLocation I also have the following code: private void MainForm_FormClosing(object sender, FormClosingEventArgs e) { Properties.Settings.Default.MainFormClientSize = this.ClientSize; Properties.Settings.Default.MainFormLocation = this.Location; Properties.Settings.Default.Save(); } The code seems to work fine. I can start the application, change the size and location and close the application. And the next time I open the application, the size and location is correct from the last time the application was closed. But something strange happens if I try to minimize and restore the application. If I already have a size and location saved, do a minimize and restore, then the initial default value are set on the form. Do I need additional code to addresse minimize / restore scenarioes ? Best of regards... :-) Tag: IBindingList Filter and DataGridView Tag: 117324

    - TB_HITTEST? OK, still trying to figure out how to determine which tray icon button was pressed. I'm at the point where if I can just get TB_HITTEST to return valid data then I should be in good shape. My question is can I use TB_HITTEST given the hwnd of the tray toolbar window and the client coordinates of the tray button? Doing so always seems to yield -10 or there abouts. I believe this reflects the total count of buttons added vs. the current count. Is there some trick to getting TB_HITTEST to work when I'm sending to the tray window??? -- Grant Schenck Tag: IBindingList Filter and DataGridView Tag: 117321

    - Play Medai Whilst Updating Tags and FileName Hi All, I'm developing a small utility which will allow me to take my ever growing list of Mp3's and update the tags and cover art to upload to my Mp3 player.Most of my mp3's don't have any tags to go on, and some don't even have filenames to indicate what they are. To this end I'm developing and application that will let me browse a list of mp3 files, and one by one: 1) Let me play the mp3 (and provide transport controls to skip around), so I can identify the track / artist and at least start to search out the detail. 2) Search for the track information using MusicBrainz web server (done this bit already). 3) Get any artwork from Amazon Web Service (done this bit already). 4) Write the tag information away and the art work to the mp3 file. 5) Rename the file [Artist] - {TrackName].mp3. I don't have any experience using media controls - so I wondered how I would go about playing an mp3 in a WindowsForm, but still be able to write to the underlying file and rename it? Is there any way I can load the file into memory and play it from there? Alternately I could allow the user to search out the details and then at the point of saving - stop the playback. Thanks All, Tag: IBindingList Filter and DataGridView Tag: 117313

I do binding collections to DataGridView. It is necessary to do filtration
and it is probably needed to realize IBindingList.
It would be desirable to see an example, as it is done.
