    - 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: Datagrid scrolling problems Tag: 63144

    - Docking a panel to a splitter window I have a Winform that has a splitter control, set vertically in the middle of my page. I have a panel over on the right hand side that has edit controls on it. What I want to do is either attach the panel to the right hand side of the splitter or make it so that when I move the splitter to the right, the expanded left hand side window covers up the panel. What type of property would I need to set within my panel to get it to dock or be sizable with the splitter.? STom Tag: Datagrid scrolling problems Tag: 63142

    - 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? Are there any workarounds or do you have any ideas as to what I should do to resolve this annoyance? Thanks, Magnus Tag: Datagrid scrolling problems Tag: 63116

    - 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.

    - Control.FromHandle Hi , We are trying to obtain the active window of a given Windows Forms application . Although most of the win API functions like GetActiveWindow and GetForegroundWindow return a valid handle , calling the method Control.FromHandle using the handle returned from the WIN API evaluates to null. All we are interested in is in checking whether a specific winform application is running or not ( Ofcourse we could have used WSH but we need to do a bit more than what can be achieved with that) through a monitoring application Any sample illustrations or alternative approaches would be highly regarded Kind Regards Bijoy Tag: Datagrid scrolling problems Tag: 63103

    - 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: Datagrid scrolling problems Tag: 63101

    - Press a button programatically Hi, Is there a way to push a button programatically (and for that matter to emulate any other key/mouse event). For example when a button is pressed by a mouse/key it caves in and events get fired. How do I cause this to happen programatically? Something like: MyButton.ClickIt()-and the button caves in The Windows calculator does it nicely-copy some numbers in the clipboard and paste them in the calculator and its buttons get clicked.

    - Char.IsControl bug? Hi, I am listening to TextChanged events in a TextBox and checking if a char is a control char via the Char.IsControl method. This works fine for regular English input. But when I change the input lang. to be "Greek", certain characters (like capital "D", delta in greek, I think) are recognised AS CONTROL CHARS by the Char.IsControl method (whereas they certainly are not control chars). I have made sure that the Application.CurrentInputLanguage setting is set to "Greek" at this point. Am I missing something or is this a bug? TIA, -Praveen Tag: Datagrid scrolling problems Tag: 63090

    - How to prevent the drawing of multiple lines on form? Dear colleagues, I refer to your help with specific graphic problem. It is necessary to create a viewfinder in graphic application. It seems that the algorithm is simple: just draw lines in specific position in according to value of some controls, track bars, for example. Next read the track bars value to find the coordinates of lines cross. It works, but I can not get real cross because the background image is being deface by lines images. The drawing procedures looks like the next: ' Picture box picbView and two track bars (trckHoriz, trckVer) are created on form. #Region "Form level variables" Dim hwnd As New IntPtr ' handler of picturebox's window Dim g As Graphics ' graphic object for drawing lines #End Region 'Form level variables Sub InitiateFormData() ' call this procedure at Sub New, located at Windows Form Designer generated code ' maximums of appropriate trackbars are equal to picture box size trckHoriz.Maximum = picbView.Width trckVert.Maximum = picbView.Height hwnd = picbView.Handle ' assigned handler g = Graphics.FromHwnd(hwnd) ' created graphic object ' get path to image and load it as picture box's background Dim strImageFile As String = Application.ExecutablePath.Substring(0, _ Application.ExecutablePath.LastIndexOf ("\") + 1) & "Viewfinder.jpg" picbView.BackgroundImage = Image.FromFile (strImageFile) End Sub Sub DrawViewfinder() ' draw viewfinder's lines ' TODO - how to prevent the drawing of multiple lines ???? Dim p_en As New Pen(Color.Yellow) g.DrawLine(p_en, 0, trckVert.Value, picbView.Width, trckVert.Value) ' horizontal line g.DrawLine(p_en, trckHoriz.Value, 0, trckHoriz.Value, picbView.Height) ' vertical line ' and we get the images of all lines ever been drawn :<<< End Sub Private Sub trckHoriz_Scroll(ByVal sender As Object, ByVal e As System.EventArgs) Handles trckHoriz.Scroll DrawViewfinder() End Sub Private Sub trckVert_Scroll(ByVal sender As Object, ByVal e As System.EventArgs) Handles trckVert.Scroll DrawViewfinder() End Sub I will be highly grateful for advices how to resolve this problem.

    - 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. (OK, for those of you with no sense of humor, I'm joking). keywords: dotnet c# fade panel control Tag: Datagrid scrolling problems Tag: 63070

    - 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: Datagrid scrolling problems Tag: 63027

    - 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?

I also tried this: listView1.BackgroundImage = new Bitmap(@"C:\test2.bmp"); But the background is still blank. Any ideas? Thanks, MP Tag: Datagrid scrolling problems Tag: 63011

    - Running DTS packages I have some code that I stole from MSKB article 321525 that I'm using in a windows forms app (framework 1.1, VS 2003) that I'm having some problems with. Basically, if I try using it on a machine that only has the framework installed, then it fails intermittently. If I use the code on a machine that has had SQL installed onto it, then it works perfectly. Running a file monitor over the machine that works shows that it is actually using the dts files (e.g. dtspump.dll) installed under c:\program files\microsoft sql server instead of just using framework files. I'm thinking that next week I need to contact MS to say "What's wrong with 321525?" but, in the meantime.... Could someone confirm that I really shouldn't need the locally installed dts files and Has anyone else had the same kind of problem with 321525?

    - TabPage issue I have a custom TabPage class the I add to a standard TabControl. I have a NumericUpDown control on the TabPage whose Validating event is tied to a method in the TabPage class. If the user types in a value, does not use the up/down arrows to change the value, I validate the Text property in the Validating event. If it is not valid I display a MessageBox then set the cancel property of the CancelEventArgs to true, then call the NumericUpDown control Focus method, then select the text of the NumericUpDown control. This all works great if the user uses the Tab key to move to the next control, or clicks another control on the current TabPage. The problem arises when the user after typing in what is an invalid value into the NumericUpDown control then clicks another Tab in the TabControl. Here is what happens. 1. Enter invalid data on the current TabPage 2. Click another TabPage on the TabControl 3. The MessageBox is displayed twice with the originating TabPage visible. 4. The TabControl switches to the TabPage that was clicked 5. The MessageBox is displayed again. (Third time) 6. Anything after this causes the MessageBox to display and I can not leave the TabPage that was clicked. Can any one provide any ideas as to what is happening?

    - Forms that won't Dispose Hi MS & All others, I've been investigating a memory leak in my application which is proving particularly hard to fix, and I came across something very unusual. I've determined that the leak is caused by a particular form that won't "dispose". I'm using a program called ".NET Memory Profiler" to check to see whether there's still an instance of my form even after it has been closed & disposed. After doing some testing, I've now come across a very unusual situation: In a simple little app, I can load Form2 from within Form1, display it using ShowDialog, close it (and then call Dispose on it from within Form1) and the memory profiler reports that there are 0 instances of Form2 currently running, just as it should be. However, if I have a context menu on Form2 and I display it (handling Form2's click event and showing the menu from code), and then close & dispose it, it remains in the list of instantiated classes. I have tried this several times, and was able to end up with a list of over a dozen instances of Form2 despite the fact they had been closed and disposed of. This ONLY ever happened if I'd clicked to show the Context-Menu, if I didn't do that then Form2 would happily Dispose. Is there some quirk where extra code is needed to dispose of a Form after a Context Menu has been shown? I tested this with a MainMenu instead and it Disposed just fine. Could this be a memory leak in the Framework? I'll be happy to post a sample project demonstrating it, but in order to see the problem you will require some sort of profiling tool capable of examining the Heap. I'm using VS.NET 2003, Framework 1.1, WinXP Pro. Many thanks, Alex Clark Tag: Datagrid scrolling problems Tag: 62993

    - PreProcessMessage Does anyone know how to use this method on a Form or a Control? I've tried overriding it and it never seems to get called. Am I missing something? I want to intercept mouse messages to stop them being sent to sub-controls - similar to design time controls in VS. Tag: Datagrid scrolling problems Tag: 62992

    - Cannot Open Inherited Forms KB 814732? I create a base form then I created an inherited form. This works fine. I do some work in both of the forms. This works fine. Suddenly, there comes a time when I cannot display a design view of the inherited form. This is independent of the code that I write. I believe this is the same issue that is described in KB 814732 except that the error that I get is "Object Reference is not set to an instance of the object". What does the KB article mean when it says "Copy the assembly in the directory where WinRes.exe is located." What assembly? Where is WinRes.exe located? I'm buried in jargon. Thanks in advance for your help. Glen Tag: Datagrid scrolling problems Tag: 62991

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.

Thanks,
Brandon
