    - Pick value in dropdown combo on WebBrowser page I have a WebBrowser on a form and I am automating some data entry on pages displayed therein. I know how to select/click on a radio button or checkbox. I know how to set the value of a text box. But, how do I programmatically set the value picked in a drop down? 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.

    - evaluate function for WebBrowser control Consider the following line of javascript: var checkBoxes = document.evaluate('//input[@type="checkbox"]', doc, null, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null); Is there a way to accomplish this with the WebBrowser.Document? Is there something equivalent to the evaluate method? On a related note, is there code that I could run that would return a collection (HtmlElementCollection) of just the checkboxes on a form?

    - 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.

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.

    - 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: Pass parameters to Windows Service 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?

    - 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?

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.

    - 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.

    - How to fix the AutoGenerateColumns I was also being driven crazy by this problem of reappearing columns in the designer even though I had sub classed the DataGridView control and set base.AutoGenerateColumns = false in the constructor. After analysing ones that seemed to be OK vs ones that were having the problem, I found the corruption to be in the resx file for the datagridview. At the bottom of the file (open with an xml editor), there will be a number of <metadata > elements. Keep the one for your binding source and delete all the ones for the columns. Now regenerate your solution and then try re-opening your designer. If you are as lucky as me, then your problem should have disappeared. Good Luck.

    - Progress bar sometimes refuses to refresh (but works OK with DoEve I have a .NET 3.0 (VS2005) Winform app. The UI invokes a long-running BRL process (synchronously, on the same thread). The BRL raises events periodically to tell the UI to update a progress bar. Works OK, most of the time. But if the user does something as simple as clicking on the form, the update of the progress bar stops. I found that calling DoEvents (rather than just doing a Refresh) in the event handler that updates the Progress bar "fixes" the problem. But I've read posts saying that DoEvents is evil. And I can see why. But simply doing a Refresh in my event handler doesn't suffice. So is there another way ? (short of reworking the app to run the BR process on a separate thread...which introduces a different can of worms) Here's the event handler in the UI which exhibits the problem.

    - Wrong size of UserControl Hello I have a UserControl sized to 100; 200 When I drop it in my form the initial size is 100;200 (as I prefer). Then I decided to change the size of my UserControl to 200;200 but although I have not set any value to the size of the dropped control in my form, recompiling the project does not affect the new size of the user control in my form. Surprisingly if I reset the Size property of my user control in the form, the size changes to 150; 150! It seems some how, there is a DefaultValue for Size property. How can I solve my problem? I prefer when I resize my UserControl in form designer, it affects all places it is used. another statement is I want my default size affects from the main UserControl class. Thanks in advance.

    - Using a default login dialog I have noticed that several applications (Internet Explorer, Remote Desktop Connection) uses the same user credentials dialog. There is a screenshot here: http://www.due-net.dk/images/LogonBox.png Is this some internal Microsoft dialog, or is it available for use with other applications? I need a user credentials dialog for an application I am writing, and although I could easily make my own, and even duplicate the look of this one, I was wondering if it is available for general consumption.

    - Signing WinForms ClickOnce app with Certificate Chain Hello all, Now this is a bit involved, so please bear with me :o) I have a Thawte code signing certificate and I am trying to use it to sign C# WinForms project for ClickOnce deployment via the signing screen in VS2008. I was issued PVK and SPC files by Thawte which I used to create a PFX file including the full certification path. The PFX file can then be used with Visual Studio. Thawte use an intermediate certificate for code signing so my certificate is chained to the Thawte root certificate via their intermediate certificate. Creating the PFX file with the full chain embeds the intermediate certificate which is necessary as client machines will only include the root. Our build server includes the full certification chain in its store in order to complete the signing process and performing a fresh install of the built application on this machine correctly shows the 'green tick' for a valid certificate. Unfortunately when I try and perform a fresh install of the click once application on a client machine it shows a 'yellow warning' instead as it is unable to complete the certification path. The machine does not have the intermediate certificate installed but it should be included in the signature. Now, if you check the digital signature for the setup.exe file (right click -> digital signatures) then you can see that the signature is valid and that the certification path is complete, indicating that the certificate included the full path as intended. This leads me to believe that there may be two types of 'code signing' going on, one a 'normal' authenticode type signing and another xml signature of the manifest, that are working inconsistently. It seems that the signature on the setup.exe includes the full chain, but when trying to install the application it indicates the chain is broken. From googling this (see http://www.eggheadcafe.com/software/aspnet/32016113/clickonce-certificate-ca.aspx and http://groups.google.com/group/microsoft.public.dotnet.framework.windowsforms/browse_thread/thread/8c46df2acf25d54/4c1c4221f69fa09e) it looks like this was confirmed as an issue with VS2005 that was intended to be addressed. Any suggestions on how I can get the ClickOnce installation to find the intermediate certificate? Note that getting our clients to install the intermediate certificate as a one-off step is not an option... Thanks very much, David Tag: Pass parameters to Windows Service Tag: 117299

    - ContextMenuStrip: ToolStripScrollButton = unrecognized control??? Hi there, I'm trying to create a custom ContextMenuStrip. Everything's (basically) fine, but when the vertical space needed to display all items is less than required, those ScrollButtons show up at the top and bottom of the menu. Digging into how to paint these I found out that these buttons are made up from System.Windows.Forms.ToolStripScrollButton. However, .Net doesn't seem to actually publish these controls. I'd like to: a) paint the background in a different color b) increase the vertical space the buttons are consuming c) paint a border around them While a) and b) are not all too important, I need to somehow draw a border around the buttons. Also, if the ScrollButtons appear, they seem to be drawn over the control AFTER it has been painted. That is, if I paint a border around the menu itself, that border is replaced by the white area of the ScrollButton. Any pointers ..?

    - Using flow breaks in a context menu I am trying to create a context menu strip (ContextMenuStrip object) that has labels and textboxes (similar to the 'Filter For:' menu item when right clicking on a record in a table view in MS access 2003). Iâ??ve written the following code, but it doesnâ??t do the trick: ContextMenuStrip mnu=new ContextMenuStrip(); mnu.AutoSize = false; mnu.Width = 400; mnu.Height = 100; mnu.LayoutStyle = ToolStripLayoutStyle.Flow; FlowLayoutSettings fls = mnu.LayoutSettings as FlowLayoutSettings; fls.FlowDirection = FlowDirection.LeftToRight; // // label1 // ToolStripLabel label1 = new ToolStripLabel("Label1"); label1.Name = "label1"; mnu.Items.Add(label1); // // textbox1 // ToolStripTextBox textbox1 = new ToolStripTextBox("textbox1"); textbox1.BorderStyle = BorderStyle.FixedSingle; mnu.Items.Add(textbox1); fls.SetFlowBreak(textbox1, true); // // label2 // ToolStripLabel label2 = new ToolStripLabel("Label2"); label2.Name = "label2"; mnu.Items.Add(label2); // // textbox2 // ToolStripTextBox textbox2 = new ToolStripTextBox("textbox2"); textbox2.BorderStyle = BorderStyle.FixedSingle; mnu.Items.Add(textbox2); fls.SetFlowBreak(textbox2, true); Note that I am trying to set a flow break after each text box, but no flow breaks actually happen, all the controls appear side by side on one line. What am I doing wrong? Am I applying the flow break on the wrong object? Iâ??ve tried to apply it to textbox.Control and textbox.TextBox to no availâ?¦ Thanks, Aviad.

    - Developing media player GUI I start developing a commercial media player. Most of the form would contain a picture or a video rectangular(the data and its representation do not matter here-just the frame and the control buttons). Some other rectangular areas are devoted to information data (one can see Windows Media Player as a model, but certainly not as a replica). The external panels should be unique and also all the control buttons. What technologies should I consider to the GUI(I mean like WFP or other commercial libraries)?

    - Odd runtime error (I've already fixed this. I'm just curious exactly what happened.) I have a Dot Net 2.0 solution with a main winforms project and multiple class libraries. The main winforms project and one of the class libraries both have a reference to an external dll, which is compiled in a separate solution and which I've also been tweaking on recently. It is possible that the 2 projects may have been referencing different versions of the same dll during the time of this problem. What happened was this. The main project calls a method of that class library. That method in turn calls a method of the external dll. Even though everything was compiling normally, the program crashed in the winforms code on the call to the class library, with a MissingMethodException. I was unable to step into the class library's code, even though everything was compiling normally and the method obviously exists. When I detached and reattached the external dll reference in both projects and recompiled, the problem went away. Anyone else ever see anything like this?

Hello everyone,

I have a Windows service that is begun, and I would like be able to tell a
number of parameters or cause an event (from the outside) to do some tasks.

for example, I have initiated a service windows and there is a task
scheduled for some time to be launching a process which is in the Windows
Service.

Now, I use a Timer class to launch the task, but I want to know whether
there are other options or ways to do it.

Thanks in advance, best regards. Sorry my english
