    - Setup project and Windows 2000 I have a Windows Forms .NET application that I've built a Setup project for that includes the installation of the .NET Framework and MSDE (using the MSDE Deployment Toolkit). The install & uninstall works fine when the O/S is Windows XP. The installation works on Windows 2000 as well, but the application doesn't appear in the list in "Add/Remove Programs" so that it can be uninstalled. What am I missing? Thanks in advance!

    - Hidding a window and preventing Alt-Tabbing to it I'm trying to hide the main form of my application, as I want all of the user interaction with my application to come from interacting with a notify icon with a context menu in the system tray (which I have working). I've figured out how to hide the form easy enough, set the WindowState to Minimized and ShowInTaskbar to False. What I can't figure out is how to prevent the user Alt-Tabbing to the window, as its still visible in the Alt-Tab menu. I can set the windows FormBorderStyle to FixedToolWindow or SizeableToolWindow and it will no longer show up in the Alt-Tab menu but now it will now minimize to the bottom left of the desktop just showing the windows title bar instead of being completely hidden! Does anyone know of any way to completely hide a window visibly(so no part of the window is visible anywhere), with no icon on the task bar or on the Alt-Tab menu? All I really want is to be able to run a notify icon in the system tray and a context menu for the icon but I'm don't know of any other way to do it other than to run it in a enclosing form. I've been wondering if making my application a service make things easier but I've no experience with programming services and it seems a bit of overkill for what I'm wanting to do! Any advice would be most appreciated! Cheers, Danielb Tag: Creating VS Studio like control Tag: 81159

    - Hello, Japan? My application is so successful that it needs to go global. The only problem is that that means Japanese. I don't know the first thing about making a Japanese language application. I know I have to use Unicode, but that's about it. In case it matters, the user will be presented with a dialog, and he can choose, dynamically, which language it should be rendered in. So, it isn't a matter of linking a particular resource file for Japanese on one machine, and a different one for English on a different machine. Both must be available, based on user choice. Is there a simple "Hello, World" application for the .Net framework, but in Japanese? Or any sample applications that make use of Japanese? I don't even know where to find a Japanese font. Any help would be appreciated. Tag: Creating VS Studio like control Tag: 81155

    - GroupBox disables event handlers in the user control it contains. Hi, friends, In my VC# windows program, when I put a user control in a GroupBox, all the event can no longer be handled, for example, DoubleClick.

    - Excel Add-In InvalidCOMObjectException On Shutdown Hi Guys, I've created an Office.CommandBarPopup Add-In for Excel that launches a Windows Form as a modal dialog when a button within the CommandBarPopup is clicked. However, when Excel is shut down I am receiving an InvalidCOMObjectException error. This is even happening even though the form has no embedded controls. It doesn't happen if the dialog isn't instantiated. Is there a procedure that needs to be followed when destroying forms from Excel add-ins? Best regards, Jim...

    - Panel & keyboard focus I have a panel and some of my controls on it (each control is derived from Control, not from UserControl). I need to delete the selected control by pressing the Del key. How it can be done? Panel does not process any keyboard events. Also I don't want to delete any controls when focus is on the other controls of the form. So the scenario is something like this: 1. User clicks on some of my controls (panel receives focus) 2. User press Del key (control removes from panel) 3. User press Tab key (the focus is received by another control of the form, but not a control of the panel) 4. User press Del key (nothing happens) So the main question is how can I monitor focus state of the panel and process the keygboard input? Thank you very much. -- With best regards, Mikhail Tag: Creating VS Studio like control Tag: 81138

    - create object dynamically hi guys, i just have a doubt about this one... i have several class that just basically do CRUD operations (create, read, update, delete) now for example on my delete function, i want to create objects dynamically based on TableName.. this is my current line of code Public Sub ActionButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Select Case TableName.ToLower Case "employee" Dim o As New BusinessLogic.EmployeeController o.Delete(1) Case "gender" Dim o As New BusinessLogic.GenderController o.Delete(1) Case "more of this on my code" Dim o As New BusinessLogic.[other]Controller o.Delete(1) End Select End Sub now i want to make this line of code shorter, maybe by doing this Public Sub ActionButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Dim o As New BusinessLogic.[TableName]Controller o.Delete(1) End Select End Sub note the [TableName] here is a property i created, so passing a EMPLOYEE as the TableName will Dim o As New BusinessLogic.EmployeeController and then i can call the delete function, just want to load object dynamically here.. i hope i made my point here clear... is it anyway possible?

    - Mouse event handlers I am writing a 3D graphics demo for my students, and thought I had a really slick solution for handling the interaction with the mouse. There are several ways to interact with a 3D world, and I have attached a mouseDown event handler to my OpenGL panel (control). What I want to do, is based upon which mouse button was pressed associate the proper mouseMove event handler with the control. OK, so I have a From with several controls, including a few OpenGL controls I created. I attached the mousedown to an OpenGL control. In the callback I want to associate the MouseMove and MouseUp event handlers. I first tried something like this in the MouseDown event handler: m_MouseMoveDelegate = new MouseEventHandler( camera.Trackball ); this.MouseMove += m_MouseMoveDelegate; m_MouseUpDelegate = new MouseEventHandler( My_MouseUp ); this.MouseUp += m_MouseUpDelegate; This associates the mouse handlers with the entire Form though, not the control. I am rather clueless on the sender semantics. I tried casting it to my UserControl (OpenGLPanel), but that led to very bad behavior. Not sure why. I also need to retained the mouse position of the mouse down event. The problem above is either the "this" identifiers, or trying to save the mouse position from the mouse down event. Casting this to screen space provides somewhat better behavior, but not ideal. Questions: 1) Is there something fundamentally wrong with this design? 2) Is the sender one of the controls I registered the MouseDown event handler to? 3) In particular, is it the control in which I pressed the mouse? 4) Can I associate a MouseMove event to the sender? Note, I do not want to embed my form logic in here and test for which control, etc. FYI. The mouseUp event simply removes the event handlers: // Disconnect the MouseEventHandler this.MouseMove -= m_MouseMoveDelegate; this.MouseUp -= m_MouseUpDelegate; Tag: Creating VS Studio like control Tag: 81122

    - Getting the keyboard state in MouseMove In my windows app, I have an event handler for the mouse move, and want to allow for constrained interaction using the shift or control keys. I can not figure out how to get the state of the shift, control or alt key modifiers for the mouse. The mouseEventArgs does not seems to have anything, and casting the sender to a control and trying to inquire has led to compiler errors. This functionality exists in the Drag and Drop event args, but not the mouse. How do we determine the key modifiers for the mouse in .NET? Roger Tag: Creating VS Studio like control Tag: 81120

    - How can I custom draw a window title bar Hi All I've tried without success on google and google groups to find the answer to this, but without success - but I do recall it being discussed... In my application, if I want a slightly modified Title Bar on some forms - eg so that it is coloured yellow rather than using the system scheme, is there a way that I can do this? I know I could do FormBorderStyle = None, and draw my own window including my own title bar (lots of references how to do this). But I don't want that (well if it's what I have to do, then I guess I will!) I just want a standard title bar with a different colour. Any ideas?

    - Dynamic Properties. What the point? I have been playing around with the "Dynamic Properties" of the controls and for the life of me, I can't figure out why would anybody care about using feature. It looks like the only things that this feature does is store and retrieve values from the app.config file! The thing is that, there is already a way to do this during runtime!! In fact, that's what happens once the app starts running under "Windows Form Designer generated code"!! Other than just some kind of time saver (arguably) is there something that I am missing here, is there some big benefit on using this feature that I don't know about? Thank you.

    - Unresponsive UI during lengthy processing Ok, I'll admit it, I'm a winforms newbie. I'm writing an image processing program that, by its nature, gets into some fairly lengthy processing cycles. As long as I don't touch the UI while it's working, don't alt-tab away and come back, don't minimize and restore--in short, as long as I sit there like a dope waiting for the processing to be completed, things are fine. My UI updates itself at the right times with progress bar updates, updates to the PictureBox control that has the image in it, and even updates to a RichTextBox that shows some debugging type output. But the second I do anything at all (even just dragging the window around), the entire UI stops showing any updates. If I bring some other app on top of mine and then bring mine to the front, it doesn't re-draw at all, leaving me with an empty white box where my UI should be. Obviously, this is irritating as heck because frequently I'd like to be doing other things, like checking my e-mail and stuff, while my program is working. I realize that there is probably some general principle of writing winforms apps so the UI stays responsive no matter what the rest of the app is doing, but I'm cluless as to what it might be. Worse, being new to windows programming in general (having finally taken the plunge out of the crusty world of the command line app), I have no idea what I should be searching for in the Visual Studio documentation. Any hints, even just a pointer to the relevent docs, would be greatly appreciated! Thanks. Tag: Creating VS Studio like control Tag: 81105

    - Custom double buffer Hi I've got some problem doing double buffer. Here is my problem: I've got custom control on which i paint some data (chat messages, lets call it ChatControl), this control is puted on a scrollable panel. Of course i've set right styles on a ChatControl: //styles this.SetStyle(ControlStyles.AllPaintingInWmPaint, true); this.SetStyle(ControlStyles.DoubleBuffer, true); this.SetStyle(ControlStyles.UserPaint, true); this.SetStyle(ControlStyles.ResizeRedraw, true); Everything is ok,but i've got some performance problems. Chat messages arrived in every 5 seconds, and i call on ChatControl Refresh(), so my OnPaint method is called - and thats ok. But control is repainted more times than on in every 5 second refresh: user used scroll, or something like that. And now i want to made some additional double buffer, because i want to draw remembered graphic (thru bitmap), than draw it again - because its neccesery when i only refresh control. I know i should do something like this: Bitmap bmp = new Bitmap(this.ClientRectangle.Witdh, this.ClientRectangle.Height); Graphics g = Graphics.FromImage(bmp); and than i should draw on g but there is a "small" problem - beacuse i know control size after i draw something (thats depends at chat messages count)! so how i can get a bitmap from my base graphics or how to create bitmap that will resize automaticly to my graphic size ?

    - Toolbar buttons have blue line at bottom edge of images Windows Forms App Gurus, I have a toolbar on a form. Some of the buttons have images on them. Buttons with images have a blue line that is like a focus indicator at the bottom edge of the image (all toolbarbuttons with images have this). I can't figure out how to get this turned off.

    - My User Controls Tab disappeared Hello, I have seen alot of issues regarding controls not appearing in the "My User Controls" tab. My problem is that this tab is not shown at all. My colleuges got this tab when installing VS, but I did not. I have tried to create one myself but no controls are added (yes, I have created the controls correctly). Any suggestion on how I can make the default "My user .." appear? awiklund Tag: Creating VS Studio like control Tag: 81048

OnMouseOver and lsides back when looses focus? Also, it has bookmark.
