    - Type.GetType(non corlib) - bug?? Hi All I am trying to get a point from the LParam of the message by over-riding the wndProc in my C# application. I think this is the only way to capture the WM_NCLBUTTONUP message in .NET. Now my problem is, when I do something like, Type t = Type.GetType("System.Object"); System.Type t1 = Type.GetType("System.Drawing.Point"); Point pt = (Point)m.GetLParam(t1); When I execute the above code I get a valid type for t, but t1 comes as <undefined value> which means i can't extract the point from the message m. Is this a bug in .NET that you cannot get the type for the types which are not in mscorlib.dll ??? thats just a guess 'coz I couldn't get the type information for TextBox or Pens etc. Can anybody confirm this to be a bug? Is there a fix? The other question is, I can get a value in lparam property of the message, Is there any way to translate this into point without using the GetLParam method of the message?

    - Overflow or underflow in the arithmetic operation when showing form Hi, When I first installed Visual Studio 2003, I noticed I was getting the following error when showing a form: A first chance exception of type 'System.ArithmeticException' occurred in system.drawing.dll Additional information: Overflow or underflow in the arithmetic operation It is being thrown on the line that attempts to add the controls to the form's controls collection (in the windows forms designer generated code region). Looking at the call stack, the error is occuring on the following method call: System.Drawing.Font.Initialize({Name="Microsoft Sans Serif"}, 8.25, Regular, Point, 0, false) System.Drawing.Font.Font({Name="Microsoft Sans Serif"}, 8.25, Regular, Point, 0, false) System.Windows.Forms.ControlPaint.FontInPoints({Name="Microsoft Sans Serif" Size=11.0}) System.Windows.Forms.Control.get_DefaultFont() System.Windows.Forms.Control.get_Font() System.Windows.Forms.Control.AssignParent({AMS.UI.Controls.ctlPlantExplorer} ) System.Windows.Forms.Control.ControlCollection.Add({System.Windows.Forms.Tre eView}) I've searched the web for fixes for this and found out that it has something to do with the FPU. I also found the following workaround: ---------------------- '************************************************* ' FixFPU: Fixes a bug in .net that causes Windows ' forms to mess up if the FPU not set up '************************************************* <System.Runtime.InteropServices.DllImport("msvcrt.dll")> _ Private Function _controlfp(ByVal IN_New As Integer, ByVal IN_Mask As Integer) As Integer End Function Private Const _MCW_EW As Integer = &H8001F Private Const _EM_INVALID As Integer = &H10 Private Sub FixFPU() _controlfp(_MCW_EW, _EM_INVALID) End Sub ---------------------- This is all well and good in my own application that I have the source code for, but the bug seems to affect all .Net applications (C# ones too). If I install a .net program and try and run it, the program crashes with the same error. This problem did go away for a long time on my machine, but it's back now with a vengance. I haven't installed any major programs or changed the .net configuration that might have caused this. I'm using Visual Studio .net 2003 and .Net Framework 1.1. My CPU is an AMD Athlon. I never had this problem when using the .net Framwork 1.0. Any help would be appreciated. It's basically crippled my machine as I can't run any .net apps. Best Regards, Trev.

    - Bizarre error--cannot create window handle I am getting a very bizarre error. Says something about system memory and then Cannot create window handle I have a form with constructors. 1 is passed nothing (new document) 2 is passed a class having a strong dataset (open document) the form has a datagrid and binds to the dataset(the form has a member variable that gets set to the class having the dataset) The grid binds to this class. if from my MDI form I open a document works great. if I click new, it does soemthing like dim f as new frmMyformName f.mdiparent=me f.show I set a breakpoint on new statement I trace into it and it gets by the constructors and the New() contructor makes a new empty class and binds that empty dataset to the grid. Then on f.show I trace into it it goes to form.load it goes so far in there and then bombs out to the f.show call in the MDI form. Says system out of memory error or something and then Cannot create window handle. I can't seem to discover the real problem Any ideas would be appreciated.. All else works fine. This did work right before but I discovered I needed another class and when i made thoses changes it no longer works correctly. I am not sure why. Thanks, shane Tag: Images dont appear Tag: 63171

    - Datagrid scrolling problems I have a datagrid that when you hit the end key the cell changes to the last cell on the row but it doesn't scroll all the way over. It scrolls so you can see the second to last column but not the last. When you hit home it seems to work fine. Has anyone seen this behavior before? I have other grids and none of them show this to be happening. The only way I've gotten it to work right is by making the last four columns skinnier. It seams it will only scroll beyond a certain point and if you make the columns small enough it won't have to scroll beyond that point. I told it to scroll the maximum amount and it did take it to the end properly so I don't think that the maximum is set wrong. Any help is appreciated.

    - Screen Configuration Mechanism ? Does anyone have any useful links or ideas on allowing end-user screen configuration in .NET ? What I am after is a mechanism that allows developers to create rich client forms in some sppropriate "default" layout, but which then allows a privileged user to manipulate the screen layout at run-time (to affect all or selected users), ie. hiding particular panels, controls or grid columns, changing the display and tab order of panels, controls (within panels) and grid columns, etc. I'm not sure how the configuration UI will actually work at present but I'm open to suggestion. The mechanism should incur minimal additional effort on the developer. Tag: Images dont appear Tag: 63144

    - Cannot show inherited forms in design mode It seems that every now and then, totally at random, Inherited forms stop working in design mode. Once they stop working, I can never get them to work again. When I try to show the form in design mode it says "An exception occurred while trying to create an instance of MyClassName. The exception was "Specified cast is not valid."". The form compiles just fine and everything works well except for this error message which leads me to belive that Visual Studio.NET is more to blame than me. ; p. I have tried to delete the resx file and have it recreated but that doesn't get me any closer to a solution. Is this a known bug?

    - Tree control focus frustration Hi; I've built the guts of an explorer style application in C#. It has a tree view on the left showing a series of nodes that are relevant to my user, and as they click on each one, the right-hand side of my window shows the particular panel that's relevant to the selected node. I have one minor frustration, however. What I'd like to do is focus on the first control within the newly chosen panel. I know which control this is, and I can transfer focus to it by Select()'ing it, but once the tree control has finished its AfterSelect() event it steals focus back again. I've got a dual monitor setup and I can step through my tree control's AfterSelect() event handler. My new panel is selected, completely drawn by calling Update(), the first control on the panel is selected and focused on and the tree loses focus. Finally, when I step off the end of AfterSelect(), focus magically snaps back to the tree. I'd really like focus to stay on my newly selected panel rather than the tree. (1) Am I fighting a pointless battle here? Should focus stay with the tree? (2) If it's not extremely rude to move focus to the new panel and leave it there, how do I do it? Thanks, Andrew.

    - Using DirectX 9 with .NET Don't know whether to post this to a DirectX newsgroup, but I'd post it here :) I have written a C# MDI app utilising GDI+ to do the drawing. Performance is terrible. (I have double buffering, but this causes other problems, especially at high zoom levels - on large documents). Is it possible to use DirectX9 to paint MDI child windows? I have seen some samples, and they seem to use a busy loop to continually redraw a window, calling Application.DoEvents after each iteration. Why do they need to do this? Would it work to have multiple MDI childs and update those in the loop? Why not just respond to paint events instead of replacing the message loop? Maybe I just don't get it.... :) Anyone have any ideas? Any advice? Anyone actually done this with any success? Thanks - Paul Wardle Tag: Images dont appear Tag: 63101

    - Fade from one Panel to the other I am building an application that will fade one panel to another panel. Both panels will have picture boxes in them (thumbnails). This is what I have tried: private void fade(System.Windows.Forms.Panel fP){ for (int i = 255; i >= 0;i--){ System.Threading.Thread.Sleep(10); fP.BackColor = System.Drawing.Color.FromArgb(i, 255,255,255); System.Windows.Forms.Application.DoEvents(); } } There is another Panel under the one being passed in to the function. It has two problems. One it flickers like crazy, and two (now this I don't get at all) it does not become transparent at all. It just fades the form color. (At the time of testing the top panel had no images in it, but the bottom one did) Am I doing something wrong? (Well of course you are idiot) But what? I don't know much about GDI, but is it possible to take a image of my control that is fading out and replace the control with that image and fade the image out? Would that be any better. (Thinking out loud). If you could, please point me in the right direction. If you had sample code to do this I would erect a large alter in your name and sacrifice many chipmunks in for you.

    - Panel Fill with Nested Controls Greetings Everyone. I have been trying to fill a panel control with linear gradient. (Isn't everyone?) This control contains a number of label controls. I placed code in the panel's paint event handler. While this does fill my panel as expected it also performs the fill on each of the label controls resulting in a rather tacky display of gradient excess. I have confirmed that, to no surprise, the paint routine is being called once for the panel and again for each constituent control. It also appears as though the panel itself is the sender of all the events and each of the labels' dimensions are being sent in the ClipRectangle property. I am not sure I understand the reasoning behind this. Can someone explain that? More importantly, would someone mind sharing their clever solution to getting only the panel to paint? (I've considered comparing label locations to ClipRectangle X and Y but that seems clumsy.) TIA - Eric Tag: Images dont appear Tag: 63027

    - IE Icons I'm embedding IE in my app, and I want to display a toolbar with the back, forward, stop, home, etc icons of IE. Is it possible? Or is there some (C) problem? If possible, where do I get them? Tag: Images dont appear Tag: 63025

    - Need Expert Opinion on design issue Greetings all, Ok, I've developed a .NET application that integrates into the Windows shell as a namespace extension (think of Scheduled Tasks and you'll get the general look of my app). Since I've written it in C# using the 1.1 framework, I decided to support the XP look by calling Application.EnableVisual Styles(), however here lies the problem: It appears that calling EnableVisualStyles() works as long as its' called from an executable. Unfortunately, in my case, I have no starting executable. Technically the executable is Windows Explorer (explorer.exe) which calls into my DLL through various interfaces. To make a long story short, calling EnableVisualStyles within my DLL eventually leads to a crash of the Windows exlplorer interface, so I'm left with one option to get the XP style interface, and this is where I need expert opinions: If I include a manifest named explorer.exe.manifest and install it into the windows directory, everthing works great. My windows inherit the XP interface, however so does other programs that are tied to Windows explorer, such as scheduled tasks. So my question is, should I install a manfiest that potentially alters other programs interface just to get my app to have the XP style interface, or should I just leave it alone? The reason I ask this is that this is going to be a commercial application, and I want it to look professional (i.e. when run on XP, one would expect it to have an XP interface), but am I crossing the line by installing a file that could have affects on other apps that are not mine? All opinons are welcome! Neil Axe Exalien Software Tag: Images dont appear Tag: 63024

Can you post the code for your form? It sounds very odd that nothing should
work.

Do the images appear in design time?

My images except toolbar images appear at design time but
dont appear at run time.

If you are using 'Application.EnableVisualStyles', call
'Application.DoEvents' directly after the call to 'EnableVisualStyles'.
