    - 4 pane SplitContainer The SplitContainer divides the space in two, either horizontally or vertically. I'd like to divide the space in four. By adding more splitters, the problem is that they don't keep in synch automatically. It'd be nice if when the mouse hovers in the center of the four regions a cross movement icon is displayed, and movement in the two axis is allowed. With the solution of adding more splitters the user is forced to first move in one direction and then in the other one. What do you recommend to achieve this? Thanks.

    - Adding forms into a panel Hi everybody: I am adding several forms into a panel to give MDI appearance to my panel.. Though the forms inside my panel looks fine, I have three problems: 1. The focused form does have the title bar activated (it is gray, like the inactive forms) 2. The only way to bring to front a form is clicking the title bar (in a MDI container, the user can click at anyplace in the form and it gets activated). 3. Cascade, horizontal tile and vertical tile functionality is not provided. Well, the tile and cascade window organization can be implemented, but I do not know how to deal with the focus and mouse problem. Am I doing something wrong? There is another way to implement this functionality? Thank you in advance Ernesto Tag: Exposing custom collections as datasources for VS in design time... how to do that? Tag: 92332

    - MDI Child Controls If I have a second form that is a mdichild, let's say frm2 and I want to update a textbox control pragmatically... In my MDI parent, I open 5 instances Dim f as new frm2 private sub OpenForm() for i = 0 to 4 f = new frm2 f.mdiparent = me f.show end sub Now, from my parent, I want to update a textbox1 in the active mdi child, how can I? When I just try f.textbox1.text = "some text" it updates the control on the last handle created. I tried finding the active child but couldn't determine how to go from there after I got it.

    - Forms are re-locating Hi, I have an application which shows forms on two different independant screens. The Windows desktop is spread across these screens. The forms are all set to manual positioning, and so to show a form on the second screen, I simply set the coordinates to be on the second screen and that is where it goes. It now seems to have developed a problem however: When I trace through what is happening all the coordinates get set correctly, and then I call Show() for the form. When show returns, the forms coordinates have been changed to show it on the first screen. I can't trace into the Show function, as it's part of the framework, but something weird is happening. Has anybody seen this before or got any idea what could be going on? Thankyou in advance. Paul Cheetham. Tag: Exposing custom collections as datasources for VS in design time... how to do that?

    - FindDialog for RichTextBox problem Hi! I created a FindDialog for RichTextBox. I have 2 problem with it: - when I ShowDialog() my FindDialog, it got the focus and the RichTextBox stop displaying its current selection (it apparently need the focus to draw it), so when the user click "Find Next" I select the next match, but the user has no visual feedback :-/ - I also try the RichTextBoxFins.Reverse option, doesn't seems to work at all! Any ideas? -- If you're in a war, instead of throwing a hand grenade at the enemy, throw one of those small pumpkins.

    - Combo refresh/binding problem Hi- I have two combobox controls (among other controls) that are all bound to dataset0 from the "Main" table. Combobox2 is bound to a column that contains a FK (system_id) which corresponds to the PK from the "Systems" table. These combobox's also function as picklists and as such are filled from two corresponding datasets (dataset2 contains the system_id (PK) and SystemName column from the the "Systems" table. The contents of Combobox2 depends on the selected item in combobox1. usage model is as follows: The controls are all bound to dataset0 by a hand-coded procedure at form load. This works fine. Combobox1 is populated by dataset1.fill. The user can scroll through the dataset0 records from ""Main" table by navigation buttons. The displayed string values in the comboboxes change accordingly. When the user wants to make changes, he opens the current record for editing but using a button which unlocks the controls. He then makes a selection from dataset1 loaded in Combobox1. All good so far. The change event on Combobox1 fires, and the contents of Combobox2 should then be loaded by dataset2 which takes a parameter based on the selection made in combobox1. This is used a parameter to the dataset2 which should populate combobox2 with the appropriate choices for the selection made in ComboBox1. But what is reflected in combobox2 is a bunch of rows that all say "System.Data.DataRowView" I should mention that this was a port from a VB6 where this worked correctly. The combobox2.datafield property was set to an integer (system_id) representing a FK in a column in dataset0. When the user chose the value in Combobox1, the value was sent as a parameter which was used to a recordset which yielded values to populate ComboBox2. This recordset came from the Systems table. ComboBox2.boundcolumn was set to Systems.system_ID (the PK), and the Combobox2.listfield was set to Systems.systemname. Since the control was bound to FK system_id from dataset0, whatever value it was sitting on, would display the correct systemname. Obviously, I have no idea how to make this scenario work in .NET. Any help would be appreciated. -- thx, jf kaminsky Tag: Exposing custom collections as datasources for VS in design time... how to do that? Tag: 92315

    - What makes this code slow This code resets a form with two cbo's (comboBoxes) and one datagrid. The first cbo (cboSelection) selects a main table and filters the second cbo. The second cbo (cboView) selects the secondary table which determine the dataAdapter used to fill the dataGrid. Both cbo's are populated by filling dataAdapters. This code just empty's the datagrid, cbo's and dataset so the user can start over to view another set of data. \\ Private Sub btnResetForm_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnResetForm.Click 'Clear the datagrid Me.DataGrid1.DataSource = Nothing Me.DataGrid1.TableStyles.Clear() 'clear the dataset _dataSet1.Clear() DAL.da010JobFrm.Fill(_dataSet1, "tbl010Job") 'cboSelection Me.cboSelection.DataSource = _dataSet1 Me.cboSelection.DisplayMember = "tbl010Job.JobNumber" Me.cboSelection.ValueMember = "tbl010Job.pkJobId" _bStillLoadingCboSelection = False _bStillLoadingCboView = True End Sub // What makes this code slow?

    - Studio 2005 Style Drag & Drop Hints I am creating a UI framework that is in someways similar but also very different to the .Net IDE. The user can drag & drop framed panels anywhere, float them, split them, etc, etc. What I have been trying to do is recreate the Drag&Drop hints as in Visual Studio 2005 IDE. I have tried BilBlt, adding a transparent control over the drop control and other methods. Some get pretty close to working but I'm not quite happy with the solution.

    - Application.ThreadException becomes unwired? Hi, I'm writing a C# application that uses Application.ThreadException to handle uncaught exceptions gracefully. However, I'm having a problem where it is failing to catch some exceptions, and I've determined this is because the event handler is becoming unwired: if I reinstall the handler just before the code that causes the exception, the Application_ThreadException method is called. Do you know of anything that can cause this to happen? I've tried to replicate the problem in a less complex testbed project, but have had no success.

For checking the check boxes or clicking the text boxes to gain focus or using tab for navigating focus down to the controls which are not in screen area. When I scrolled and clicked any control which is not in screen height area then my form automatically gets scrolled to the 0,0 location and am unable to check the checkboxes.

    - Satellite Assemblies and Win Forms Hi, Iâ??m creating a project which uses Satellite Assemblies (SA) to isolate localized resources. The solution contains eight library projects, one GUI control project and one Windows Form project. I know how to approach SA for library projects, but I do not have any idea how to do it for Windows Forms and Controls. Should I use Localizable properties on every win form and win control that I create and copy resource files associated with form/control to SA? Or should I just create resource file in SA with the exact name as the resx files of form/control? Which approach is better? Or maybe there is another, different approach that I should consider? Which approach will allow me to modify form/control in the design view? --Start: Different question but still about resources Can I use String Resource Tools to create resx and corresponding cs file and then split them into two separate projects â?? resx and string file (string file is created by String Resources Tool) will go to SA, and cs file to new library project? Or maybe I can access cs file in file created by SA? --End. Iâ??ll be grateful for yours help. Kind regards, Jakub G.

    - Problem using API CreateBitmap function and keeping transparent co I have a C# DLL that loads a bitmap object from a PNG file. Thanks to Bob Powell's advice i managed to access the Bitmap data using the lockbits method and then call the Windows API function CreateBitmap successfully. Then the DLL provides a COM interface which returns the handle to the bitmap created using CreateBitmap function. The problem is that the initial bitmap has a transparent background color, and when using the CreateBitmap function, the bitmap seems to loose this color, which is then replaced by black (maybe something to see with ColorPalette). Furthermore, the createdbitmap is a 32bit bitmap so the alpha layer which contains transparency informations should be the same. So i don't know what i missing or doing wrong. here is the code that creates the bitmap : Bitmap bitmap = (Bitmap) Bitmap.FromFile(@"C:\tmpicon.png"); BitmapData data = bitmap.LockBits(new Rectangle(new Point(0,0), bitmap.Size), ImageLockMode.ReadOnly, PixelFormat.Format32bppArgb); IntPtr HBITMAP = CreateBitmap(bitmap.Width, bitmap.Height, 1, 32, data.Scan0); NB : I also noticed that when opening the PNG file with MS Paint, the transparent color is replaced by black, whereas opening it with Photoshop or Windows Picture viewer, the transparency is visible. Can't explain this... I'd like to understand what im missing to keep the transparent color on the created bitmap. Thx for any help.

    - MouseUp event "falls through" FileDialog and activates control underneath Hello, In my app I have a UI control that responds to MouseUp events and opens a FileDialog. If an item in the dialog is double-clicked (instead of clicking on it then clicking OK) AND that item is over my UI control, the final MouseUp of the double-click is registered by my control and its handler is called, opening the FileDialog again. The events happen in this order: MouseDown MouseUp Dialog Opens Double-click in dialog Dialog closes MouseUp DialogOpens, etc. I'm looking for suggestions on how to correct this. I've tried removing the MouseUp handler when the FileDialog is opened, and adding it beck when it is closed but that doesn't work; it still gets called. I've tried looking for a way to "eat" the MouseUp but haven't found a way that works. For example, purging the event queue or marking the event as being handled/ignored. So, any suggestions?

    - Installing Merge Modules from C# Windows Form Application (not using a setup and deployment project) Installing Merge Modules from C# Windows Form Application (not using a setup and deployment project) Hi, Currently, we have an InstallShield project that creates a setup.exe that only installs 20 or so merge modules. It does nothing else. We then have our own custom, C# Windows Form application that installs our software applications. It does this by copying files, creating registry keys, etc. So what I'm trying to do is get rid of the separate InstallShield setup.exe. We want one setup application that installs both the merge modules we need and our software applications. Is there any way to run/install merge modules from a C# Windows Form application?

Here is my code: public class Toto { public string Idr; public string Name; public Toto(string id, string name) { Idr = id; Name = name; } } ... and the ui part: Toto[] totoList = new Toto[3]; totoList[0] = new Toto("id1", "name1"); totoList[1] = new Toto("id2", "name2"); totoList[2] = new Toto("id3", "name3"); comboBox1.SelectedIndex = -1; comboBox1.DataSource = totoList; comboBox1.DisplayMember = "Name"; comboBox1.ValueMember = "Idr"; When the program reached the last statement (...ValueMember) I got an : "Cannot bind to the new display member.

    - Triggering a Control Event This is probably a silly question, but is it possible to trigger a button click event from inside the Form_Load event? I know I can just call the Button_Click routine, but I'm not exactly sure how to setup the parameters. Thanks in advance!

    - Control loaded in IE problem I'm loading a control in IE. If the control is loaded from the server then AppDomain.CurrentDomain.FriendlyName contains the URI of the server that the page is from. If my control is loaded from the GAC on the client machine then the FriendlyName is "Localhost". Is there a way to get the URI from within the control. I've used JScript to pass the document.domain into an OBJECT PARAM but this requires me to change Security Settings to allow "Initialize and script ActiveX controls not marked as safe". I'd like to avoid this whole issue. -Steve Tag: Exposing custom collections as datasources for VS in design time... how to do that? Tag: 92181

    - Datagrid row selection In windows explorer you can select multiple files using combinations of ctrl and shift clicking, then if you click and hold the mouse button on one of the already selected files you can drag all the selected files to wherever. I'm trying to reproduce this kind of behavor in the datagrid, but the problem is that when I click and hold the mouse button on an already selected row all the other rows get cleared and only the clicked on row is selected! I thought I could get around this by keeping track of all the selected rows, intecepting the MouseDown event on an already selected row and then restoring all the rows that are supposed to be selected using DataGrid.Select. However, this doesn't seem to work. It appears that the rows get cleared *after* the MouseDown event and, therefore, after my code to restore the selected rows. This is very frustrating! Does anybody have any ideas on how I can make this work? I have to restore the selected rows while the user still has the mouse button down so that they can drag them.

    - System.InvalidOperationException: Failed to load ImageList I have seen talk of this around but none of them seem to be exactly my problem. Anytime I compile the source of our application on my laptop I get the following error when I run it: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.InvalidOperationException: Failed to load ImageList. at System.Windows.Forms.ImageListStreamer..ctor(SerializationInfo info, StreamingContext context) ... This happens on anybody's computer who runs the program I compiled on mine. If they compile the same program I did it runs fine on both my computer and theirs. I looked into this futher and noticed that the ResEditor can't even open the .resources file generated when I compile the program. It fails to load the imagelist resource. What is the problem? It is as if the resource compiler is not serializing the imagelist out correctly. I already tried to do a repair install of Visual Studio 2003. I have a Windows XP SP2 system on a dell laptop.

Hi all,

I have some custom collections (ArrayList of custom Objects) and I want to
display them using typical Windows form controls (DataGrid, Combo). What
should I do to expose them as valid datasources to these controls? What if I
want that these collections work with Visual Studio on design time in order
to allow me easy create grid columns on design time? Can you point me to
some examples?

Thanks in advance
Sammy
