    - 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. But I would rather catch whatever it is that is stopping me from leaving that control and displaying an error at that point. -- Russel Loski, MCSD.Net Tag: DataGridViewComboBox required two times click to select item Tag: 110660

    - clickOnce (more instances of installation) Hi, I have created a basic application, which is deployed as clickOnce and has some dll and one config file. Application 1 = main .exe file + dlls + one specific .config file Application 2 = main .exe file + dlls + another specific .config file ... What do I need to set to install them as completely independent ? I tried to change everything in ClickOnce Deployment Manifest file, but one application still updates the second one... In ClickOnce Application Manifest file, it seems that there is nothing specific changeable, but maybe I'm wrong. (I need also have two shortcuts in Start/Programs, but as I said, one installation always replaces the another... ) Thank you very much for any answer or idea Ondrej Dobecka ondradocasny@community.nospam ondrej.dobecka@tietoenator.com Tag: DataGridViewComboBox required two times click to select item Tag: 110655

    - System.Configuration.ConfigurationErrorsException saving config file after encrypting with RsaProtectedConfigurationProvider Hi, One of my users is getting a System.Configuration.ConfigurationErrorsException when my Windows Forms application tries to encrypt and save the application config file, but it only happens for him and no other users!? I don't really know anything about the security classes so don't have any idea where to start looking, but would love some suggestions. He gets the exception when running the application on other users' machines for whom it works fine, and other users are able to log in on his machine and use the application. So I'm guessing it's something to do with his profile but I have no idea where to look. 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.

    - 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: DataGridViewComboBox required two times click to select item Tag: 110642

    - 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: DataGridViewComboBox required two times click to select item Tag: 110628

    - 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.

    - SHGetFileInfo I am using SHGetFileInfo to get the list of icons for a bunch of files, and taking those icons and putting them in an ImageList. The ImageList is then being used with a ListView control to display the list of files and their associated icons. Unfortunately the alpha transparencies appear as black in the icons. To resolve this I tried (as per the microsoft article: http://msdn2.microsoft.com/en-us/library/aa289524(VS.71).aspx) to add a manifest to the exe file, I also changed the colordepth of the ImageList to: ColorDepth.Depth32Bit.

It works only if I launch the windows service app from VS.Net 2005 (Worked around from Main()) or from a winform test application. However, it generates a kind of security error after I install and start the service in my Window Server machine. I believe that it is related to authentication. The following is the sample code: HttpWebRequest obj = (HttpWebRequest)WebRequest.Create(webServiceUrl); obj.Method = "POST"; obj.ContentType = "application/x-www-form-urlencoded"; obj.Headers.Add("Authentication", Password); StreamWriter sw= new StreamWriter(obj.GetRequestStream()); sw.Write(Query); The exception returned: "System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.Sockets.Socket.InternalConnect(EndPoint remoteEP) at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Int32 timeout, ...." I did some research online. Many people got similar errors. However, I have not found a solution yet. Any solution or suggestion is appreciated.

    - Two-layered image control Hi to all. I need to create a custom control which does the following: - It should contain a first, fixed image. - It should manage a second image, which will change programmatically. - It should display the second image on top of the first one, updating it in response to user events; the second image will of course have a transparent background. - The second image should be accessible outside the control, and wil be used for printing on some paper forms which are, as you probably guessed, the same as the first image; this is the reason for having two separate images. I'm trying to develop this, but I'm quite confused about the various System.Drawing classes and which Windows Forms control is the best to use as my control's base class. I don't thoroughly understand the process of painting a control, and the relationships between an Image, a Drawing object and the control. My initial guess was to use a PictureBox, set its BackGroundImage property to the fixed image and use the Image property for my drawing... but I don't know how to do manual drawing this way. Is this a good approach, or there is a better one? Also, I know very little about printing with Windows Forms. What do I need for printing? An Image? A Graphics object? What else? Can someone please help? Thanks Massimo Tag: DataGridViewComboBox required two times click to select item Tag: 110598

    - Using Win32 API to track file changes with username I am trying to write an app that uses the FileSystemMonitor class. I can successfully track changes but have now been asked to add the username associated with the change. I have used DLLImport to add Netapi32.dll to the project and I can successfully get the username for create and change events but it does not return anything for delete events. After debugging the code I believe it is because the file is gone before the NetFileEnum function can get the information. Does anyone know of another place I can hook to get the information I need that may be more reliable? I am not locked into using the NetFileEnum or even the Netapi32.dll library at this point. Thanks in advance for any help! Gary Tag: DataGridViewComboBox required two times click to select item Tag: 110597

    - Global Variable I have a handfull of variables that I'd like to make Global to my application In the old VB6 days, I'd create a Module, and put them there, accessible from any form in the application However, in VS.Net 2005, I added a module, and it acts somewhat like a class, in that, to access a Public variable, there, I must precede the variable name with the module name, like: mdlVars.MyVar Is this pretty much how it's done, or, if not, what's a more acceptible approach?

    - Winform blinks when Java application is activated. Hello, We are having an unusual issue with a .NET 1.1 Winforms application. There is one particular Winform within the application that blinks, or quickly diappears and reappears on the screen, when a Java application is maximized and sharing the screen with the Winform. It almost looks like a timer, with each second causing the Winform to quickly disappear and reappear. This only occurs when the Java application is also sharing the desktop screen with the Winform. When the Java application is minimized, the Winform stops blinking. What is interesting is that this is one of three Winforms that are open and visible from the same Winform assembly, but only one has the blinking issue. So far we are able to give the users a temporary fix by changing the refresh rate on their displays to anything, then back to their original refresh rate, and the problem then completely goes away until the PC is rebooted or logged out. I've done some searches, and have found that there are bugs in the transparency of Winforms, and that setting the Transparency Key property to a Color usually resolves the issue. I tired this, and it didn't work. I'm going to try and create a project with just this Winform, to see if I can recreate the issue. Please let me know if there are any known issues concerning this, whether there is already a resolution to this problem. Thanks, Dave Tag: DataGridViewComboBox required two times click to select item Tag: 110590

    - problem with inherited Windows Form I wrote a screen that has a grid on it and a few controls. Later I needed the same screen but with a few more controls...but I still needed the old configuration. Since this was the case and since there was alot of code driving the grid I created another windows form that inherited from my original one. This worked great at the time. Today I went in to the original windows form and made a change and when I tested it out I noticed that if I open the inherited form that the grid wasn't right. In the inherited form I had made the grid a slight bit shorter because I need some room for the new controls. This size change is being ignored now. If I look at the window in the designer its showing the Grid as being locked. Its the only control that is locked....and it was set to protected not private on the original screen. This is the second inherited window that I have had this happen. Does anyone have any suggestions? Thanks, Brandon Tag: DataGridViewComboBox required two times click to select item Tag: 110589

    - ClickOnce Deployment in a Plug-in architecture context Hi all, I've been browsing through the different posts for a few days now but I didn't found the answer. We are considering the use of the ClickOnce deployment framework for a C# application that has a plug-in architecture. Plug-ins are developed as independent DLL projects. The plugins are loaded at run-time and are not really known by the application. The plugins offer different services used that can be used by other services registered to a service broker in our application. Our main application can be easily deployed with ClickOnce but we are wondering what to do with the DLL plugin projects? I saw some posts talking about manualy updating the code with the deployment API to get optional file groups for example. Those groups of files would have been added via the MAGEUI.exe tool for example. I understand how this could work. But, what happens if we want versionning also on the DLL projects? Each time a DLL is modified, the manifest files needs to be updated and our main application version incremented? Causing software update on our users computers for the whole application eventhough only a DLL has changed? Our plug-ins are role based also. Some users won't have specific plug-ins because they don't need to. So triggering a full update on the application would cause these clients to try to update for nothing right? Is there a way to successfuly and easily manage DLL projects versioning? Is this method the only way? Anybody successfully deployed this kind of project architecture with ClickOnce? Any ideas on how to resolve this? Should we still consider ClickOnce? Another question we have, is it possible to create an MSI deployment that includes all external components (databases, etc..) and that would be able to update the application via ClickOnce updates? Is it only to provide manifest files during the installation? Does someone has documented such process? I hope my questions are clear enough to inspire you answers! :) Thanks!

    - Generated Program.cs uses special way of disposing native resource Hi, To properly clean up native resources, one should always use "using (Blah blah = new Blah())" for types "Blah" that implement IDisposable. It seems to me that the code generated by Visual Studio in Program.cs doesn't live by this rule? A form is always IDisposable, so who calls the .Dispose() method on the form? [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new MyForm()); } And what about, if I change the code into this (below): [STAThread] static void Main() { MyForm myForm = new MyForm(); Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(myForm); myForm.DoSomethingThatUsesTheFormObjectExtensivly(); } The reason why I'm asking about this is because I'm having trouble with system tray icons that are left after my application exits. Normally this works fine, but when I stopped using Application.Run() things got hairy. I'm not sure the normal Application.Run() because I'm trying to use Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase.Run() instead, in order to get a clean implementation of "single instance application". My question is, why isn't the Form1() instance in the generated code wrapped into some kind of "using" statement? Is there some kind of special case going on here?

    - Login window vs Main window I have developed a Windows application which is started with a Shared Main object. The first thing it does is launch a login window. If the user types in a correct company, username and password, the login window is disposed and the main application is run (Application.Run(newprg)). This works nicely as it is. However, for the user to switch companies, he must exit the application and re-launch. How can I make the login window work with both the Shared Main and the application itself? Once the application loads, it displays items specific to the newly logged-onto company. If I could just make the application re-load itself after the login screen is launched from the app!

    - How to read Default Values from App.Config for User Settings? Hi all; How can I read default values for user settings from the app.config file? I've seen someone mention using the .DefaultSettingValueAttribute and reflection, but I don't know how to use them. I am trying to do the following: 1) Create a simple Windows App that has one user setting named "SupportAddress" and a default (string) value. 2) The default support address is in the App.Config file. 3) Make a form which allows users to modify and save the setting. This creates the User.Config file in the Application Data folder. 4) This I don't know - If the users mess up the support address value, I want to allow them to read the default value for the SupportAddress setting from the App.Config, not from the User.Config file. Of course, there will be a button named "Revert to Default" or similar on the form. What should I do?

    - Draw in form titlebar from external code? [.NET 2.0] I want to be able to insert some text into the active form's title bar, from code that is external to the form. It's essentially a timer showing time elapsed since something happened in the application. I have seen posts about using the WM_NCPAINT message, but that requires code in the forms themselves. Ideally I don't want to have to add any code or anything else to the target form(s) - I want this to be completely driven from the external code. The forms themselves don't even need to know it is happening. Can this be done? It seems to me I should be able to get hold of a Graphics object, device context, or something for the form's outer window, then just draw the text into it at the appropriate place. But from searches to date I can't see a way to do it. Any suggestions welcome. Tag: DataGridViewComboBox required two times click to select item Tag: 110559

    - Databind a nullable date to a masked textbox Is there a way to databind a nullable date to a masked textbox? I have a nullable date defined in a business object and have bound it to a masked textbox, but when I clear out the date in the field, it will no longer let me exit the field, and gives me an error that it is an invalid format for a date. (duh!) I bound it using the designer, and when that didn't work, tried doing it in code. Here's my code: Binding b = new Binding("Text", PlanListBindingSource, "StartDate", true, DataSourceUpdateMode.OnValidation, "00/00/00", "MM/dd/yy"); this.startDateMaskedTextBox.DataBindings.Add(b); Frankly, I'd be happy with 00/00/00 or even an empty string; I can check it before storing it back to the database if I need to. I just want my user to be able to blank out the field if (s)he wants to, but also be able to use the masking so they don't have to enter the slashes. Also, did the Autotab feature that was in VB6 with the Masked Edit Control not get carried into the one in .Net 2.0? I'd greatly appreciate any help you can give me. At this point, I'm ready to go back to regular textboxes and just tell the user I can't implement it the way it was in his VB6 application (how appalling!). Thanks, Robin S.

    - Newbie question: how to set focus to a usercontrol I have a usercontrol that contains another usercontrol, which in turn contains a PictureBox control. Under a certain condition, I need to set the input focus on the outermost usercontrol. But once the PictureBox control (the outermost usercontrol's grandchild) has got the input focus, I cannot transfer the focus back to the outermost usercontrol (at least not by simply invoking its Focus() member function). Why is this? What can I do to take away the keyboard input focus from that grandchild, the PictureBox control, and transfer it back to the outermost usercontrol? (I have tried to find information about keyboard focus handling that seems relevant to this question, but what I have found seems rather far removed from what I need to understand here...) Note: My application requires very little keyboard input: mainly a few keyboard-accelerators, and the copy/paste/ cut/delete key. But the copy/paste/cut/delete key must go to the right usercontrol, because copy/paste/cut/delete must be handled differently, depending on which usercontrol has the input focus (or, rather, should have it, from my point of view). In essence, I am trying to base input focus on the position of the mouse pointer: if that grandchild PictureBox control does not have the mouse pointer within its bounds, it should not receive keyboard input, i.e. should not have input focus.

    - Font problem when subclassing TextBox I've subclassed TextBox to create a version that will paint default text on its background when the control contains no text. Everything works great, except the font changes to bold or something when I select the text in the control. If I move the focus off the control, the font changes back to what I set it to. Here's a stripped-down version of my control that demonstrates the behavior (I'm using 1.1): public class Sample : TextBox { StringFormat stringFormat; public Sample() : base() { SetStyle(ControlStyles.UserPaint, true); SetStyle(ControlStyles.DoubleBuffer, true); stringFormat = new StringFormat(); stringFormat.Alignment = StringAlignment.Center; } protected override void OnPaint(PaintEventArgs e) { string s = (!this.HasText ? "<Default text here>" : this.Text); e.Graphics.DrawString(s, this.Font, Brushes.DarkGray, this.Bounds, stringFormat); base.OnPaint(e); } protected override void OnTextChanged(EventArgs e) { base.OnTextChanged(e); this.ForeColor = (this.HasText ? Color.Black : Color.DarkGray); this.Invalidate(); } public bool HasText { get { return (0 < this.Text.Trim().Length); } } } Can anyone see what I'm doing wrong?

Changing your DataGridView's EditMode property to EditOnEnter should
do the trick.
