    - 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: mouse move Tag: 110724

    - ClickOnce & proxy authentification We have developed a VisualStudio 2005 smart-client application which we deploy using .NET framework 2.0 ClickOnce. We are experiencing difficulties deploying in certain corporate environments: clients that use proxy authentification simply cannot install unless they disable the proxy which is usually not an option. Apparently this is a known issue with ClickOnce and Microsoft has released a HotFix for it: http://support.microsoft.com/kb/917952/en-us Could we please receive a copy of this HotFix? This is a huge and recurring problem that makes us look bad. Tag: mouse move Tag: 110720

I want to replace the message box with a dialog box. Can anybody help me replace the message box below to a dialog box. In other words. I want to write the new phone number on a label (named "labe1")of a dialog box (named "dialog2),instead of writing the new phone number on the label of a message box. private: System::Void dialogBtnItem_Click(System::Object * sender, System::EventArgs * e) { // Create the dialog MyDialog* box = new MyDialog(); //Fill in the initial data box->Phone = S"(650)123-3456)"; // <------ This is the phone number to be changed //Show dialog if (box->ShowDialog() == DialogResult::OK) { MessageBox::Show(box->Phone); //<-----I tried to change this line } } Tag: mouse move Tag: 110713

    - 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?

    - ReportViewer and Terminal Services I have an application with vb.net using reporting services local (rdlc). When I run under windows, it prints fine. When I run under Terminal Services, sometimes it takes 3 times to print. Print, and it looks like it did, but it never appears. Notepad, office apps seem to print fine. I was able to trace it. I click the Print button on the dialog box. I see the print entering the print queue, but it immediately is deleted. I print a second time, and it works. It is reproducable under terminal services. It works fine under normal Windows. Tag: mouse move Tag: 110682

    - copying an event handler in vb.net I am using vb.net and basically I am trying to build a series of buttons at runtime based on menu entries created at design time on a ContextMenuStrip What I would like to do is make the Click event of a button created at runtime execute the same event handler as the Click event of the ToolStripMenuItem. so in pseudo code newButton.OnClick = menuItem.OnClick I wondered is this possible via reflection to get the event handlers address to use in an AddHandler call for the button, but I am not sure how to go about this.

    - Prevent a window from moving when taskbar gets autohide disabled. I have a windows form that shifts position when the taskbar autohide property is disabled. The windows does not move back to the original position when the autohide property is turned back on. I have not been able to catch the position changing anywhere in my code and so I am thinking that it is taking place inside the Form class. I have tried the Locked property for my form but it doesn't make a difference. Any suggestions? Thanks, Ken Tag: mouse move Tag: 110673

    - 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. What is the best way to achieve this? Thanks in advance. Tag: mouse move Tag: 110671

    - 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? Any help with this would be appreciated Tag: mouse move Tag: 110665

    - 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: mouse move Tag: 110660

    - 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'.

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: mouse move 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: mouse move 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. The icons still have a black border. I am using VS2005, .NET framework 2.0 on an XP machine. The manifest I used is below. Can anyone suggest anything else I can do to get the icons without the black border?

    - Error when calling a webservice from a windows service Hi, I am trying to call a webservice from a windows service application. 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, ...."

    - 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: mouse move 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.

    - 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: mouse move 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: mouse move 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?

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?

A window should really only be concerned with what goes on inside it so
the correct way to do this is to capture the mouse.

The only other way to get notification of mouse operations outside your
window is to have the containing window send some message or fire some
event of its own that you can respond to.

You could, for example, have the child window subscribe to the
mouse-move events of the parent MDI frame.
