    - Best method for including a static file within project Refresh my memory please. Assume you have a static (i.e. text or xml) file you want to include in your project (VB, Visual Studio 2005). What is the best (simplest) method for accessing it programatically? (Feel like I'm forgetting something.) Tag: Damier Canvas Chelsea N51119 - www.luxury-gift.org Tag: 117547

    - The wish to pass a value from a (child) class to a (parent) form I have a MainForm class and a second class which initializes an instance of a second class which I call CommunicationManager. This is just a simplified representation of the MainForm class: partial class MainForm : Form { [STAThread] static void Main() { Application.Run(new MainForm()); } // Public accessor public string textToDisplayBox { set { this.textBox4.Text = value; } } // CommunicationManager CommunicationManager comm = new CommunicationManager(); } The CommunicationManager class has a simple function, i.e. to collect in a string the output from the comport... My troubles stem from the fact that I am unable to reference back to the form which second class is initiated. Do you have any suggestions on how to achieve this?

    - Quick question about XML manipulation I have just been told I need to write a quickie throwaway program that generates an XML file. I am a bit rusty. The program will be written using VB in Visual Studio 2005. Do I understand this correctly - If I include a reference to an XSD or DTD file at the start of the XMLDocument object, there will be automatic validation of the data as it is added to the structure? (Assuming the XSD or DTD is in an accessible location?) Tag: Damier Canvas Chelsea N51119 - www.luxury-gift.org Tag: 117544

The new DLL is causing problems with my TreeView based control so I want to go back to the 5th version of the DLL. How do I do that?

    - Newbie question: Improving graphics rendering performance. Hello everyone, I've recently picked up a project that involves rendering 100s and potentially 1000s of individual objects onto the screen. They vary in shape, size and color and some of them involve computations before they can be rendered. I'll summarize my methodology for brevity: In the Paint event I've added code that renders my objects. The objects are stored in memory (in either arrays or collections of some sort). Each object has a "Draw" method which knows how to draw the given object. I loop through all the objects and 'draw' them onto the graphics object. So ar pretty standard stuff and to be honest I haven't really noticed a problem with the rendering (I'm double buffering). I may potentially need to render many more objects. I was hoping if someone could explain what, I imagine, must be a basic concept. Imagine I have a 25 objects that I'm rendering on the screen like: o o o o o o o o o o o o o o o o o o o o o o o o o Currently I'm looping through all 25 objects and adding them to the Graphics object. Suppose I only need to show the middle 9 so (x represents NOT rendered): x x x x x x o o o x x o o o x x o o o x x x x x x I could just create a Region object and mission accomplished (from a rendered point of view), however, from a algorithm point of view I'm still looping through 25 objects and calling their "draw" method. I had thought about checking if the object lies in the Region before doing my computations thereby potentially saving some cycles per object but some objects are complex and trying to determine if it lies partially in the rendering Region and partially outside it would probably take up just as many, if not more cycles. So I guess my question is am I stuck looping through all my objects and adding them to the Graphics object regardless of were they lie (in or out of the rendering region) or is there a more standard method for accomplishing this? I hope I've made my self clear. Thanks, Stephan Tag: Damier Canvas Chelsea N51119 - www.luxury-gift.org Tag: 117536

    - MessageBox sounds behaving strangely I understand that the MessageBox icon enumeration values map to system sounds. This seems to be fairly predictable, even if the mapping sometimes don't make sense. However, I've found a scenario in which it doesn't behave correctly. In a textbox's Validating event, when I call a MessageBox.Show, the first time it plays the System's Default sound, no matter which icon value I choose. Subsequent calls use the correct sound: Private Sub MyTextBox_Validating(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) _ Handles MyTextBox.Validating MessageBox.Show("This is an error","Error",, MessageBoxButtons.OK, MessageBoxIcon.Error) ' This plays the system's Default sound MessageBox.Show("This is an error","Error",, MessageBoxButtons.OK, MessageBoxIcon.Error) ' This plays the system's Critial Stop sound End Sub Even if I change the first MessageBox's icon to MessageBoxIcon.None, it still plays the Default sound. It only seems to do this in this event. When I paste the same code into a button click handler, it behaves as expected. Is this a bug in the messagebox?

    - Thumbnails & Listviews Hi there, I'm currently developing a program to manage my image collection. The main form contains a llistview in which the location and filenames of these images are displayed. When switching the listview to Tile mode, I want to display the thumbnails of these images. My image collection contains over 4.000 images so it doesn't make any sense to populate the needed imagelist with over 4.000 thumbnails. It makes more sense to populate the imagelist with thumbnails of the images which are currently visible in the listview, but how can determine which images (listviewitems) are currently visible in the listview? Further more; how can determine changes in the visibility (after scrolling or browsing)? It should be possible, because I think that Windows Explorer (in tile mode) uses a same sort of technique, but I can't figure it out myself. Can anybody help me out?

    - Sort DGV after edit, reposition grid doesn't work when user hits Enter or Tab I have a DataGridView bound to a binding source which is bound to a BindingList<obj>. The first column is [Name], and the user can edit this column. I have it set to be edited programmatically, and have DoubleClick event calling BeginEdit. When the CellEndEdit event is fired, I save the record, re-sort the binding source, go find the record, and set FirstDisplayedScrollingIndex to that row. This works great if the user clicks somewhere else on the grid or the form while he is editing. If the user hits Enter or Tab, it ends up on the next line, or one column over on the same line, and not on the line where I asked for it to be repositioned. I think what is it doing is repositioning programmatically, and then processing the Enter or Tab key and putting the user back in that location. Any ideas how I can handle this to suppress the Enter or Tab keys in this instance? Or if I am wrong in my supposition, what is wrong and how I can fix it? Thanks, RobinS.

Yesterday we made a minor change to one of our components (let's say with the name MyAssembly), and incremented it's version (AssemblyVersion: from 0.1.7.0 to 0.1.7.1). We did the Publish with ClickOnce, but when the users know want to run the application they get this error: "Unable to install or run the application. The application requires that assembly MyAssembly Version 0.1.7.0 be installed in the Global Assembly Cache (GAC) first."

    - 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: Damier Canvas Chelsea N51119 - www.luxury-gift.org Tag: 117425

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 ?

    - Redirecting to ClickOnce application fails Hello, We have implemented a few years ago a "zero touch" deployed smart client application for .NET 1.1. We ported now this application to .NET 2.0 and deploying it with ClickOnce. 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: Damier Canvas Chelsea N51119 - www.luxury-gift.org Tag: 117413

    - 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: Damier Canvas Chelsea N51119 - www.luxury-gift.org 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.
