    - 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: Form.Closing event not fired always when i call Form.Close method 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: Form.Closing event not fired always when i call Form.Close method 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: Form.Closing event not fired always when i call Form.Close method 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: Form.Closing event not fired always when i call Form.Close method 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: Form.Closing event not fired always when i call Form.Close method 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: Form.Closing event not fired always when i call Form.Close method 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.

    - Adding an event handler to a dynamically populated control I've got a subroutine that can do something when the image in the Picturebox is doubleclicked, that works just fine Private Sub pb1_DoubleClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles pb1.DoubleClick ShowImage(pb1) End Sub Private Sub ShowImage(ByVal ctrl As Control) Dim PicForm As New MyForm Dim img As Image img = Image.FromFile(ctrl.Tag) PicForm.LoadFile(img) PicForm.ShowDialog() End Sub Now - Let's say I'm adding a picturebox to a panel, dynamically, and I set the image dynamically (small image) - but I want to add an event handler, so that when the small image in the new dynamically created Picturebox is doubleclicked, it will call that function Dim picBox as PictureBox= new PictureBox ' How can I change the above code to handle this new dynamically created control - and then how can I add an event handler to do the same thing for the new dynamically created control (when double-clicked)?

    - Datagridview help I'm looking for help with datagridview. I have a form that works with a Databale bound to a datagridview. However I only want to display and edit a few colums (in a different order than they appear in the underlying datatable). When I set autogeneratecolumns to false, as in the example below, the columns show up with no data in them and are not bound to the underlying datatable. The example below works fine when I allow autogenerate columns. Howver I get a datagridview which includes all of the columns in the underlying datatable. Does anybody know what steps exatly autogeneratecolumns takes, so that I can replicate them to create the databinding manually? Any help greatly appreciated. --------------------------- MyItemTable.Clear() myItemAdapter.Fill(MyItemTable) MyItemTable.PrimaryKey = New DataColumn() {MyItemTable.Columns("refnum")} MyItemTable.Columns("refnum").AllowDBNull = True dgvInvoiceItems.AutoGenerateColumns = False dgvInvoiceItems.DataSource = MyItemTable With (dgvInvoiceItems) .EditMode = DataGridViewEditMode.EditOnEnter .Columns.Add("qty", "OrderQty") .Columns("qty").DefaultCellStyle.Font = New System.Drawing.Font(Control.DefaultFont, FontStyle.Bold) .Columns.Add("soldqty", "SoldQty") .Columns.Add("unitprice", "Price") .Columns("unitprice").DefaultCellStyle.Format = "c" end with Tag: Form.Closing event not fired always when i call Form.Close method Tag: 110543

    - 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? If I'm not doing anything wrong, anybody got an idea for a workaround? TIA Jared Tag: Form.Closing event not fired always when i call Form.Close method Tag: 110535

    - Graphics dpi not correct I am in the load event of a user control. I get its Graphics with this.CreateGraphics() The DpiX and DpiY are both always 96.0 This does not vary, regardless of the actual resolution of the screen. I have tested the value in code that is executed after the load event, and the value is the same. The docs say that Dpix is "the horizontal resolution supported by this Graphics". I don't know if this is supposed to mean the current resolution. If not, it doesn't seem to be a very useful datum. I have to draw accurately on the screen regardless of resolution. Any solution would be helpful. Thx Marc Tag: Form.Closing event not fired always when i call Form.Close method Tag: 110527

    - Is it possible to set a TextRenderingHint for an entire appplication? Hello, I would like to be able to have my app use Clear Type (or at least antialiased) text rendering. Is there a way to enable this for an entire application? I don't see any properties that allow for setting a TextRenderingHint on an individual control (Label for example), but since this is supported by GDI+ I don't see why Windows.Forms in general wouldn't support it. I could derive my own controls of course and override their Paint behaviors, but that seems like a lot of bother for something the standard controls should support. Is there a way to do this?

    - How to capture my form I am developing Windows Forms application in C# using VS 2005. The application draws some shapes on the panel. I need to change color intensity on pixel-by-pixel basis (to compensate for monitor flaws). It appears that the most reasonable way is to capture the image to bitmap, update the bitmap and display it. Am I right? If yes, what is the best way to capture my panel to bitmap (using C#)?

I want to validate the text boxes when the text boxes lose focus and therefore I set an event handler for this Evenything works fine when tabbing from one text box to another within the form. But when the user hits ok button (on the top right) no validation takes place. Question 1: Why is validation not called when the user hits ok (NOT cancel!). Question 2: I googled through the newgroups and found something about CausesValidation = true (as default for windowsforms). I couldnt find the property in the properties list of my form?

    - How to capture keystroke (Sorry for multi-posting this in "microsoft.public.dotnet.languages.csharp") Hi there, Can someone enlighten me on how to trap a keystroke in my "PropertyGrid" override. I see functions or properrites at the control or form level called: OnKeyDown OnKeyPress OnKeyUp OnPreviewKeyDown ProcessKeyPreview ProcessDialogKey ProcessCmdKey KeyPreview IsInputKey and there are probably more. I've overrided "OnKeyDown()" in my derived "PropertyGrid" class but it's not being called. Some others are called however such as "ProcessCmdKey" but I need to understand what's going on here (since I suspect that "OnKeyDown()" is really the correct function). Can anyone point me in the right direction. Thanks. Tag: Form.Closing event not fired always when i call Form.Close method Tag: 110503

    - Grabbing window messages I've got a WinForms app. Essentially all this app is is a notification try icon with an optional configuration form. I am trying to capture the WM_SETTINGCHANGE window message coming to my app. Since the app has no form, I'm doing this by adding a MessageFilter to the form. In my MessageFilter class, I implement the PreFilterMessage method to grab the event and test for the WM_SETTINGCHANGE code (0x001a). however, I don't seem to ever get that message, even though I know its getting sent. Not sure what I'm missing. During debug, I know I'm getting some window messages, but not the one I need! Any ideas on a different way to skin this? -- Darren Mar-Elia Tag: Form.Closing event not fired always when i call Form.Close method Tag: 110494

Hi,

Form1 form1 = Form1; //Form2 is created and closed inside Form1.

When I call form1.form2.Close() method the following method is called
when I run the application in few machine but not in others.

Any clues on this?

Thanks in advance.

I have only seen this happen when Form A opens Form B which opens Form
C. Closing Form A fires the closing event for Form A and Form B but not
Form C.
