    - Send messages to other window Hello. I need send some commands to other window. I did this before with VC++. So it work like this. I found this window (for example cacl.exe have text â??Calculatorâ??) then get handle of this window and then send some windows messages on this handle. My old code looks like this HWND hwndFound = ::FindWindow(NULL, " Calculator"); // Ð¿Ð¾Ð¸Ñ?Ðº Ð¾ÐºÐ½Ð° ::PostMessage(hwndFound,WM_COMMAND,IDYES,0); How I can do something like this in C#?

    - DataGridView: last column can be made smaller but not bigger Hi, I have a DataGridView control where the user can resize the columns. The control is embedded inside a Panel. When clicking on and dragging the column seperator to the right of the rightmost column, I can make the column smaller when I move it to the left. If I try to move it to the right however, my cursor is halted against the edge of the control. So the column can't be made bigger. This can be reproduced in the sample at http://msdn2.microsoft.com/en-us/library/1x64c23x.aspx by clicking Customer->View Orders in the main form and doing it on the table that appears. In that sample, it is possible to make the last column bigger again by making the whole window bigger, until its length is more than the total length of the columns, creating an open space between the columns and the edge of the window. Then the right seperator of the rightmost column can be dragged freely, up until the edge of the window. However, this trick isn't practical in my own control, since the control is too small and the total column length too long. Is there some standard way to make it behave like the list view in Explorer, where you can resize past the border of the window? Kind regards, Raf Tag: do win forms have skins like asp.net?

This works very fine, but I get problems, when the preset content is to much, because the length of the URL is restricted. IIRC this also can be solved by MAPI, but I can't find any example how to do this with C#.

    - How to avoid flicker when adding controls to a panel? Hi, I've got a flickering-problem when I try to add controls to a panel (with flow layout) at runtime. My code executes the following steps: public void BuildView() { ... // suspend layout to not perform layout each time an item is added mFlowLayoutPanel.SuspendLayout(); // remove all elements from the panel: mFlowLayoutPanel.Controls.Clear(); // in a loop I add new items to the panel: foreach (... in ...) { Panel panel = new Panel(); // set size of the panel: panel.Size = MaxSize; // MaxSize is a constant value // then the color of the panel is set panel.BackColor = Color.CornflowerBlue; // after all the panel is added the the panel with the flow layout mFlowLayoutPanel.Controls.Add(panel); } mFlowLayoutPanel.ResumeLayout(true); } Every time the method BuildView() is called, the panels are flickering. What went wrong? I thought that SuspendLayout() and ResumeLayout() will avoid that? How can I avoid flickering every time my panels are added to the flow layout panel? Thanks a lot for your answer in advance. Best regards, Ralf Tag: do win forms have skins like asp.net? Tag: 110747

    - Datagridview and the Enter Key Hi all, I have a datagrid that doesnt allow the user to edit. When the user clicks a row, the whole row gets selected. I'd like it so that when the user has a row selected and presses enter, a new form is opened and passed data from the row. At the moment, when I press enter, I can get the window to open, but the selected row moves down one. Is there any way I can surpress this behavior when pressing enter? Many thanks Simon Tag: do win forms have skins like asp.net? Tag: 110743

    - Child form focus problem Hi all, An application I am woking on consist of a main form. On the main form there are several possible ways for the user to open a non-modal child forms to display even more information. The problem I am encountering is about loss of focus. Let's say here, that initialization of the child form takes about =BD second, from the point where the window is first shown to the point where all controls have been rendered and set with data. Now, on the main form there is a datagridview which is updated on intervals. The problem occurs the user clicks a button to open a child form. The child form is created. But before initialization of the child form has finished, the DataGridView on the main form is updated. Seemingly because of this, the main form gets focus and is moved to the front, and the child form is moved to the back. The user can manually put focus on the child form again and continue working, but tuhis is a behaviour that is very anoying to the end users. Have any of you encountered something like this before? The non-modal strategy is by design. The users want to be able to go back to the main form, without closing the child form. Therefore, I'm searching primarily for any help on the focus problem, and will only use a modal child form strategy if no resolution to the problem can be found. Thanks in advance, Christer Tag: do win forms have skins like asp.net? Tag: 110739

    - Windows Form App and VPN I have some clients who have users who reside outside of the company's network. The company is going to allow remote access through a VPN on the server for access to the SQL Server database. I want to have my forms app which will run on the client machine to automatically open the VPN when the program starts and close it when the program ends. That way, the clients doesn't have to set anything up and they don't have to worry about how the data is accessed. Is it possible to this from a windows form app and if so what operating systems would the client have to be running in order to do this? Bill Tag: do win forms have skins like asp.net? Tag: 110729

    - OnPaint automatically call e.Graphics.Clear()? Hello. I have a question about OnPaint override. For example, if i have the following code in my inherited form class, private Brush _brush = Brushes.Black; private RectangleF _rect = new RectangleF(0,0,100,100); private int counter =0; protected override void OnPaint(PaintEventArgs e){ if (counter==0){ counter++; e.Graphics.Clear(Color.White); e.Graphics.DrawString("Test", this.Font, _brush, _rect); } } I expect the OnPaint method will do nothing after the first call. That means, the string "Test" should stay on screen if the form is not resized/moved/covered by other windows. However, in reality, the OnPaint do the e.Graphics.Clear() automatically. I'd like to know if that is possible for me to stop that behavior. In my application, my form contains many individual text strings. The strings are updated periodically individually. I would like to render the updated strings only, not rendering the whole thing for every string update. Thank you very much for your help! Gilbert Tag: do win forms have skins like asp.net?

    - mouse move I want to detect and receive a event to my MDI window when the moves outside of the window.. I am unable to receive events. I know there is a case of sending a manual message (George Shepherd's Win FAQ) before opening Top Level windows or doing anything that take mouse focus away from the MDI window. Considering the scope of our application, this I feel might be an effort. Is this the only way? or any other way possible? VJ Tag: do win forms have skins like asp.net? Tag: 110725

    - Filtering key strokes Hi, having a card reader attached to the PS/2 keyboard interface, I would like to filter the keyboard input, so that the input from the card reader does not reach the GUI controls. I tried setting KeyPreview=true on the form and catched all input with the KeyDown event. In order to detect, if the input comes from the card reader, I need to check a sequence of at least 10 keys. So I collect the keys in KeyDown and if it's a card reader sequence, I trigger a special action for it. If it's normal user input, I need to "forward" the collected key strokes to the form. The second part is the complicated one. Having a sequence of key strokes in an array of type System.Windows.Forms.Keys, how do I resend these to the application? Sendkeys only accepts a string and seems to not support all values of the System.Windows.Forms.Keys enum. Is there maybe a way to resend keystrokes using the integer values captured from the KeyValue member of the KeyEventArgs? bye, Marc T. Tag: do win forms have skins like asp.net? Tag: 110724

    - What are my options in this Windows App? I am creating a Windows Forms app that will use SQL Server as the database. The app will be used in the following ways. 1. It will be used in the Clients office where the app will sit on the clients desktop pc and connect to the database on the server. 2. It needs to be used by those outside of the office network. ex. a remote office that is not a part of the network where the database is residing. 3. I might have users on the road that with wi-fi access need to connect to the office database. I don't want to create a browser based app using ASP.Net. I don't want to use Citrix. Here's what I think are my options. Am I missing any? which would you recommend? 1. Create a windows forms app that sits on the client and a web service that sits on the server that connects to the database. The user does something on the client and a call is made for data to the webservice which returns data to the client. 2. The app creates an opens up a port upon startup and accesses data directly and then closes the port upon exiting the app??????????????????? Any other suggestions or recommendations?

    - DGV CellValidating event not letting new forms be focused I have a form with a DataGridView in an MDI application that handles the CellValidating event. If I set DataGridViewCellValidatingEventArgs.Cancel to true, I can't navigate off the cell within the form as expected. However, If I use the MDIParent to create a new instance if the child form, the focus remains on the error cell in the first form even with the new form in the foreground. The behavior that I would like to create here would be for the focus to remain in the error cell when that form is in focus, but for new forms to be able to be created and focused on their own.

    - DataGrid Binding / Threading Slow Updates I have a VB.NET Windows Form that contains a datagrid control that uses databinding to an object. I have tried using threading and updating the databound object (by marshalling to the UI thread) by using a separate thread however there are still delays when 32000 rows / items are added. It stops other windows from responding for a brief second. I also have an animated gif on the form and that stops responding. Is is possible to have the datagrid run completely within a separate thread, or have two UI threads run in the form so that the form and animated gif is not affected when the datagrid updates?

    - Validating bound text box I have a windows form (.net 2.0). On this form I have a BindingSource. I set the DataSource to a dataset that is created in code then "built" using the ReadXMLSchema method. I have have bound a textbox to one of the fields in that BindingSource that is of type int. If I type anything but an int, I cannot do anything. I cannot close the form, I cannot set focus on another control. No exception is thown. The DataError event on the BindingSource doesn't fire. The Validating event on the TextBox fires and in fact I have had to check the value so that I can raise a message if the item is not a number.

He and all other users have the same .NET version; I installed it as part of the application install and noone had previous .NET runtimes on their machine. In my live application I get a standard windows box saying the program had a problem and had to be closed, do I want to send info to MS. (That's despite having set a ThreadException handler which normally logs and shows a message for all unhandled exceptions, which is slightly odd in itself.) I created a test app to determine where it's failing, and it crashes in this method: private void btnProtectConfiguration_Click(object sender, EventArgs e) { string provider = "RsaProtectedConfigurationProvider"; Configuration config = null; config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); ConfigurationSection section = config.ConnectionStrings; if ((section.SectionInformation.IsProtected == false) && (section.ElementInformation.IsLocked == false)) { // Protect (encrypt) the "connectionStrings" section. section.SectionInformation.ProtectSection(provider); // Save the encrypted section. section.SectionInformation.ForceSave = true; config.Save(ConfigurationSaveMode.Full); } MessageBox.Show("ok"); } The info in the standard .NET exception handler is at the bottom of this post. In my test app he is able to save the config file fine without encryption, using this code: private void btnSaveConfig_Click(object sender, EventArgs e) { // Same stuff as ProtectConfiguration, but without the protection. // Checks if we can open and save the config file. Configuration config = null; config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); ConfigurationSection section = config.ConnectionStrings; section.SectionInformation.ForceSave = true; config.Save(ConfigurationSaveMode.Full); MessageBox.Show("ok"); } He's also able to do RSA encryption and decryption using the RSACryptoServiceProvider class; I included in my test app the sample code here: http://msdn2.microsoft.com/en-us/library/system.security.cryptography.rsacryptoserviceprovider(VS.80).aspx If anyone can suggest why this exception could be occurring and why it's attached to just this user I'd greatly appreciate it! fyi the reason I'm doing this is that during application install my application opens and encrypts the config file so connection details can't be read by the casual observer. Not perfect security but good enough, providing it runs! many thanks, - Rory ************** Exception Text ************** System.Configuration.ConfigurationErrorsException: An error occurred executing the configuration section handler for connectionStrings. --- > System.Configuration.ConfigurationErrorsException: Failed to encrypt the section 'connectionStrings' using provider 'RsaProtectedConfigurationProvider'.

    - How to install a font in VB.Net? How can you 'install' a font, using VB.Net? I tried System.IO - just copying it, but it didn't add it to the system's list of installed fonts immediately. when my app loads, it populates a combobox with the installed fonts - then, I need to install a font, clear the list, and then fill the list again, including the new font.

    - Get computer's Windows or Windows Fonts directory In vb.net 2005 - I know that to get the system directory, it's system.environment.systemdirectory. I need to find the fonts directory - - which is normally inside the Windows directory - so how can I locate either or both of these (if I find the windows directory with a global variable, then I can at least concatenate '\fonts' to it)?

    - Application.Run questions I need create winForm application with this architecture I have code [STAThread] static void Main() { Application.Run(); } Now I need show Icon in tray bar and attach some "context menu strip" to this icon. So when user select one menu item - for example with name "settings" I need show Settings window and after user change it and close window I need get it on "tray bar thread" (my main thread) and keep wating some other action from user. So. I don't need main window for this app and I have some question here 1) The first question can I show icon in tray if I didn't create form? 2) How show notify icon without creating form? 3) as I see after main thread run this Application.Run() this thread became frozen. So How I can continue work with it? Tag: do win forms have skins like asp.net? Tag: 110642

    - windows program deploy question Hi, I did a batch build on a 2005 .net windows app and copied the exe file to a machine running windows windows 2000. When I tried to run it I got the error missing dll mscoree.dll. I then tried to run it on another machine with windows xp and the error was missing .net frame work. Just wondering to install on the windows 2000 machine should I do a project installer and if I do this will I still need to install the .net framework on the 2000 machine? thanks. -- Paul G Software engineer.

    - Activated and Enter events not called on MDI children I'm having trouble with the MDI activate chain of events that happen as a result of a Ctrl+Tab event in my client's MDI application. A mouse click on an inactive MDI child executes normally but Ctrl+Tab event processing handling is only partially handled. The active MDI child window is changed but this is not being reflected in the MDI parent because the Activated and Enter events attached to the MDI children are not being called. Even though the next MDI child has been activated by the Ctrl+Tab, the MDI parent is unaware of the change. The application itself is pretty complicated with a number of third party controls involved to obfuscate the issue. In Win32, I'd simply intercept the WM_ACTIVATE or WM_MDIACTIVATE message and I suspect that the Activated event is attached to that message. Since the MDI child is properly changing its Z state and painting itself in a fashion consistent with activation, I'm pretty sure that the Ctrl+Tab is being at least partly processed. What can I do to narrow down the location of the failure or otherwise circumvent the problem by detecting the mdi activation event upstream? -- Richard Lewis Haggard www.Haggard-And-Associates.com Tag: do win forms have skins like asp.net?

    - Shared settings I have a solution with multiple projects, each with its own EXE, and its own Properties.Settings.... They are all part of the same solution. I want to have a set of settings that are shared by all of the EXEs. That is, each project will have its own set of settings that are a superset of the solution settings. Under 1.X with appSettings, I could do this with by specifying a file= attribute (KB article ID 555396) and the target was integrated into the settings of all referencing projects. Under 2.0, appSettings is replaced by applicationSettings and the file= attribute is gone. http://www.devx.com/dotnet/Article/34273/1954?pf=true discusses how to distribute settings in multiple files, but the resulting files must be stored in the Properties folder of the project and therefore can't be shared by multiple projects. Can each project's settings be set up so as to derive from the solution level settings? I'm sure that there must be a way to handle this under 2.0, but I can't find it.

WinForms does not support this, but Infragistics version 6.2 and later
includes this functionality including a styling app that would be used
by a graphic artist.
