    - VB Equivalent to Access Form BeforeUpdate Event? Hi, We have two fields in just about every table for UpdatedBy and UpdatedOn which we want to update if there are any changes to fields on the form. In Access we typically use the Form_BeforeUpdate event to accomplish this. How should we do this in vb.net? I've explored using the RowChangeEvent to assign values to the dataset, but of course this triggers another RowChange event! Do I need to have events for each control on the form? A little help needed! Thanks. Tag: Scrollbar visual problem in a TreeView Tag: 65501

    - ListView: column width if View == List I am trying to adjust the width of a column when the View is set to "List" in a ListView object. If the View is set to "Details", setting columns widths is easy using the "ColumnHeader Collection Editor" (in Visual C#), but for the "List" I cannot find something similar. jg Tag: Scrollbar visual problem in a TreeView Tag: 65500

    - Multiline DataGrid I'm trying to upgrade the DataGrid so that I can display multiple lines of text in one row. My method is to create a new class derived from DataGridTextBoxColumn. As suggested in http://www.dotnet247.com/247reference/msgs/20/100505.aspx I have overridden the 2 GetHeight methods. However, I can't override PaintText because it is not virtual or override. As a result, when editting the text it works great. When viewing, the rows are the correct height but the text is only one line Is there an easy way to do this, or do I have to rewrite the DataGridTextBoxColumn class myself?

    - Picture box locking image Hi, I suppose I must have missed something somewhere but I'm getting an error when trying to overwrite a file referenced by a picture box. Even if I set the image property to nothing I still get an error. I read somewhere that using a filestream based on the image would eliminate this problem but it didn't. Any ideas appreciated.

    - Load next form in same window - not mdichild Hi I am fairly new to VB.net. I have a form through which I would like to load another form, like when the user clicks the next button. On the first form the user selects an option depending on which the controls for the next form are loaded after the user clicks the next button. The problem is that I dont want to open the new form in a separate window nor the mdiparent way either (i.e. like a child window within the parent). (I am trying to make interface flow much like an installation wizard where the user clicks next and further options open up within the same window) Thanks for the help in advance Michael Tag: Scrollbar visual problem in a TreeView Tag: 65484

    - System.Drawing and GDI+ Question - Please help I have a winforms control that draws a rectangle for a boarder and positions some graphical elements around the control to create the boarder effect I desired. In the control I have overriden the onpaint event and added the code to draw my rectangle and position my graphic items: Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs) e.Graphics.Clear(Color.FromArgb(255, 255, 255)) MyBase.OnPaint(e) Dim g As Graphics = pb1.CreateGraphics pb1.CreateGraphics.Clear(Color.FromArgb(255, 255, 255)) Dim myPen As System.Drawing.Pen = New System.Drawing.Pen(Color.FromArgb(187, 191, 115)) g.DrawRectangle(myPen, New Rectangle(0, 0, pb1.Width - 1, pb1.Height - 1)) pb1.Width = (Me.Width - 34) pb1.Height = (Me.Height - 29) tr.Left = (Me.Width - 32) br.Left = (Me.Width - 32) br.Top = (Me.Height - 24) bl.Top = (Me.Height - 24) End Sub Also I have added this line to the Public sub new call of the control: SetStyle(ControlStyles.ResizeRedraw, True) As you can see the rectangle is being drawn on a panel control called "pb1". When I drag this control onto a Windows form in Visual Studio the rectangle is drawn and behaves as it should when resized etc. However if I switch to antother tab and switch back the rectangle disapears, this is also the case when the solution is compiled the form initializes with no rectangle. Can somebody please help me or point me in the right direction. Tag: Scrollbar visual problem in a TreeView Tag: 65483

    - Spacing between Textbox controls I'd like to have several Textbox controls within a panel. Each Textbox will have its .Dock property set to Top. This enables all of the Textbox controls to resize as the panel resizes, which is the effect I'd like. However, since each Textbox has its .Dock property set to Top, the Textbox controls have no space between them. I'd like to have some space between the Textbox controls. How can this be easily achieved? Or should I be satisfied that the Textbox controls have a common top and bottom edge? Thanks! Tag: Scrollbar visual problem in a TreeView Tag: 65482

    - Bug w/ button having focus while in textbox There seems to be a bug where if you're in a textbox, a button can still have focus and prevent you from using the "enter" key in the multi-line textbox. This happens when you have a button and a textbox in a child form, go to another child and return back to the initial child. Here's how to re-create the problem: 1. Create a child form with a button and a MULTILINE textbox. 2. In the MDI parent form, open two of those child forms (you could do it in the OnLoad event) 3. Run the program. Two child forms should show. Let's call the child that's on top "child 1" and the other "child 2" 4. "child 1" is currently on top. Now, click on "child 2" and click back on "child 1". 5. Click on the textbox on "child 1" and hit return ("ENTER"). You will NOT be able to go down to the next line. It seems that upon re-activating "child 1", the form gives the button the focus again, but does not "release" the focus even when you put the cursor in the textbox. So, even though you click on the text box & put the cursor there, hitting ENTER still makes the form fire the Click event on the button. I have not found anything like this in the KB. If you have any workaround or know the solution please let us know. Thanks! jgc Tag: Scrollbar visual problem in a TreeView Tag: 65479

    - mdi, max child Hi, I have a windows form which has the following properties: 1) form1.IsMDIContainer = true; 2) panel1.Dock = DockStyle.Right; Then I create a new child window and set its properties: 1) FormBorderStyle = FormBorderStyle.None; 2) WindowState = FormWindowState.Maximized; But what happens is the half right of this child window is covered by the panel and it's still showing the header of the window (icon, name, min, max, and close buttons). My questions: 1) How do I make the child window maximize only on the left half on the parent window (not to make it behind the panel)? 2) How do I hide the header of the child window when it's maximized?

    - Recompiling samples via command-line We wrote a class library and then we created aprox. 30 demo projects for both C# and VB. They all have the copy local set to true and it will be like that until the end of the development. So, everytime we change the library someone has to open each sample and recompile it or have a batch file copy the new version of the dll in the bin files. I wanted to create a batch file to run the command-line for the compiler for each project, so I was wondering how can I get a snapshot of the EXACT command line that VS.NET runs in the background while compiling a project?

    - MessageBox problem Hello, I'm trying to achieve the following: 1. Have a windows form open a modal MessageBox (with MessageBox.Show()) 2. Minimize (or hide) this form along with the open MessageBox. 3. Restore the form, so it returns to its original state - with the MessageBox open modally above it (and at the same place in the form code of course - the call to the MessageBox.Show() method. My problem is whenever I hide the MessageBox (using the Hide method or Win32 api call) the MessageBox.Show() method returns (as if the MessageBox has been closed). How can I avoid this behavior and achieve steps 1-3? Thanks. Tag: Scrollbar visual problem in a TreeView Tag: 65464

    - Cannot open derived form in design view if the base form is marked 'abstract'. Hi folks! I have a BaseForm class that inherits System.Windows.Forms.Form. It has a property, whose value I need supplied by the class that inherits it. The BaseForm usees the value supplied into this property in its Load event. So, I gave the BaseForm and the property 'abstract' modifier, and put the implementation of the property in the inherited class; say MyForm. However, when I did this, I no longer can open MyForm in the design view. I'm stuck if I can't visually design MyForm.... :( Would appreciate any input, even if it means altogether different way to accomplish. thanks! -Yasutaka Tag: Scrollbar visual problem in a TreeView Tag: 65454

    - Resize to "Normal" from Maximized fails with ClientSize reset to {0,0)!? The problem: WinForms app with main form and one NotifyIcon (called sysTrayIcon in my code). Main form starts out minimized with ShowInTaskBar = False. Double clicking on the system tray icon displays the form. All looks/works well except.... If you: [1] start the app [2] double-click on the system tray icon to display the ("normal" sized) main form [3] maximize the main form [4] minimize the main form [5] double-click on the system tray icon to re-display the (still maximized) main form [6] click the "normal size" button (between minimize and close in the title bar) the main form now displays nothing more than the title bar, as if there were no client area at all. What the heck is that?! Looking at the messages going through the message pump it looks like the main form is being sized correctly the first time, but is then being resized down to 0,0 twice. Why is that happening??? Here's the custom bits to add to the default WinForms app: private void Form1_Load( object sender, System.EventArgs e ) { this.WindowState = FormWindowState.Minimized ; this.ShowInTaskbar = false ; } private void sysTrayIcon_DoubleClick( object sender, System.EventArgs e ) { this.ShowInTaskbar = true ; this.WindowState = FormWindowState.Normal ; } private void Form1_Deactivate( object sender, System.EventArgs e ) { if( this.WindowState == FormWindowState.Minimized ) { this.ShowInTaskbar = false ; } } This has me puzzled. I'm not much of a UI guy (as if you couldn't tell). The cause *is* related to my code (shown above) because the default WinForms app doesn't do this (already checked). Many thanks in advance for any help you can offer. -Jason Tag: Scrollbar visual problem in a TreeView Tag: 65450

    - Changing compile order within a project I started with two projects in a solution, one containing a BaseForm and the other an enherited ChildForm. I decided to move the BaseFrom to the second project and changed the inherited form to look in the local project for its parent. However, until the baseform compiles, the child form cannot find it. I am guessing that I may need to change the compile order in the second project to compile the baseform BEFORE the associated enherited forms. Am I correct and, if so, how to I change the order?

    - GetWindowLong on GWL_EXSTYLE fails with error 127 Simple, really. I have C# code in a Windows Form, thus: int rc; rc = Win32API.SetParent(ctrl.Handle, new IntPtr(Win32API.GetDesktopWindow())); rc = Win32API.GetWindowLong(ctrl.Handle, Win32API.GWL_EXSTYLE); if (rc == 0) { System.Console.WriteLine(Marshal.GetLastWin32Error()); } where ctrl is a control on the form (it doesn't seem to matter what type of control), and Win32API has all the relevant imports: [DllImport("user32.dll")] public static extern int SetParent(IntPtr childHwnd, IntPtr parentHwnd); [DllImport("user32.dll")] public static extern int GetDesktopWindow(); [DllImport("user32.dll", CharSet=CharSet.Auto, SetLastError=true)] public static extern int GetWindowLong(IntPtr hWnd, int nIndex); I'm doing this as a precursor to making the control a custom drop-down of sorts (subsequent lines will set WS_EX_TOOLWINDOW, HWND_TOPMOST, etc. and subclass the GWL_WNDPROC for mouse handling etc.), but I don't even get that far. In all cases GetWindowLong returns 0, and the Win32Error is 127 (which decodes as 'The specified procedure could not be found.') Anyone successfully done this from .NET?

    - capture the mouse (to grab the window content) [not with SetCapture and not with hooks] Hi there, I write a small applicaiton in C# to mimic the SnapShot/32 application functionality. I use Win32GDI rountines to grab the images and this is the easy part. The difficult part is to mimic the SnapS way of letting user to select a window he/she wants to snap. It works like this: 1. the user does whatever he wants in the system 2. he/she presses some hotkey (RegisterHotKey) and the SnapS gets active (but does not show its window) 3. instead the mouse cursor is globally changed to a cross and globally captured until the first click 4. when the user clicks a window, its image is captured my problem is the number 3. I've tried to capture the mouse with SetCapture/.Capture = true but it does not work when the capturing window is not a foreground window. I also try to change mouse cursor shape globally with no results. I am sure that SnapS does not use any hooks (and I also do not want to). the question is: how the described functionality is achieved? thanks for any clues, Wiktor Tag: Scrollbar visual problem in a TreeView Tag: 65372

    - How To Load Bitmaps Hi All, I have a C# project, I added 2 bitmap images, 1.bmp and 2.bmp in the project by right clicking and using the add existing item dialog. The bmp files now appear in the solution explorer. My question is, do they get embedded in the assembly? When I use the code as System.Drawing.Bitmap b = (System.Drawing.Bitmap)Bitmap.FromFile("c:\\myimages\\1.bmp"); it loads the bitmap and works fine. There are 2 things, I do not want to hard code the path as somebody else might have the project somewhere else. Ideally I would want to load the image from the assembly, but when I do ResourceManager rm; rm = new ResourceManager("<MyAssemblyName>", Assembly.GetExecutingAssembly()); System.Drawing.Bitmap bt; bt = (System.Drawing.Bitmap)rm.GetObject("1.bmp"); it does not load the bitmap. I think I am missing something very basic over here. Can anybody point to what might be wrong? TIA, --Saurabh Tag: Scrollbar visual problem in a TreeView Tag: 65359

    - Crystal Reports Problem: Please reply ASAP Hello All, I have a Windows application that uses Crystal Reports 9 (bundled Version) developed using VS.NET 2003 on a windows server 2003 m/c. The application has to be deployed on the client machine that has Windows XP installed. Before deploying we make sure that .NET framework 1.1 is installed on the XP machine. In the setup project, for support for Crystal Reports, we have added the following merge modules: 1)Crystal_Managed2003.msm 2) Crystal_Database_Access2003.msm 3)Crystal_Database_Access2003_enu.msm 4)Crystal_RegWiz2003.msm 5)VC_User_CRT71_RTL_X86.msm 6)VC_User_STL71_RTL_X86.msm The problem we are facing is like this: Whenever the user tries to pull up the reports, a database logon screen pops up for the report. I am unable to figure out as to why this is happening only for Crystal Reports. All the other functionality in the application is working fine without having to specify the database connection information interactively. The database server is not in the same network as this Client WinXP machine. We specify the IP address of the DB server in the DB connection string. Could this be a problem? If someone has faced this problem earlier or has any solution to this problem, do let me know. I need to resolve this problem ASAP.

How do I hide the header of the child window when it's maximized Please advice, thanks -CL Tag: Scrollbar visual problem in a TreeView Tag: 65339

    - control binding problem (MS, please respond) I've run into a problem with binding form properties to data in an xml file (through a dataset). As it turns out, I can easily bind if the data type of the property on the control is a normal datatype such as a string or integer. If the datatype is not one of the built-in types however, things go horribly wrong. Consider this xml file: <?xml version="1.0" standalone="yes"?> <SettingsData> <one> <Text>Center</Text> </one> </SettingsData> If I create a normal winforms application and add the following code to the form's constructor, it works. I get "Center" in the text box. Here's the code that works: DataSet dataset; dataset = new DataSet(); dataset.ReadXml(@"d:\development\bindtest\form.xml"); TextBox textbox = new TextBox(); Binding binding = new Binding("Text", dataset, "one.Text"); textbox.DataBindings.Add(binding); textbox.Width = 150; textbox.Height = 50; textbox.Top = 50; textbox.Left = 50; textbox.Parent = this; this.Controls.Add(textbox); I hardcoded the size and placement of the text box, but I can easily get that from the xml as well. I encountered a problem when I tried to pull TextAlign from the xml file though. I know that this would require the use of Format, so I implemented that. I changed the xml from above to look like this: <?xml version="1.0" standalone="yes"?> <SettingsData> <one> <TextAlign>Center</TextAlign> </one> </SettingsData> And I changed the code from above to look like this (changed from Text to TextAlign, and added the convert event handler): DataSet dataset; dataset = new DataSet(); dataset.ReadXml(@"d:\development\bindtest\form.xml"); TextBox textbox = new TextBox(); Binding binding = new Binding("TextAlign", dataset, "one.TextAlign"); binding.Format += new ConvertEventHandler(FormatHorizontalAlignment); textbox.DataBindings.Add(binding); textbox.Width = 150; textbox.Height = 50; textbox.Top = 50; textbox.Left = 50; textbox.Parent = this; this.Controls.Add(textbox); I also added the Convert Event Handler: public void FormatHorizontalAlignment(object sender, ConvertEventArgs cevent) { switch((string)cevent.Value) { case "Center": cevent.Value = HorizontalAlignment.Center; break; case "Left": cevent.Value = HorizontalAlignment.Left; break; case "Right": cevent.Value = HorizontalAlignment.Right; break; } } This event handler looks right to me. I followed the example from the help files. I've made similar code work with other data types such as booleans being coverted from a T or F in the xml file. DesiredType shows HorizontalAlignment. When I run this code, oddly, the event handler is executed three times. Each time seems to execute correctly. Then I get an unhandled exception from the Application.Run(new Form1()); Error creating window handle. Can anyone tell me what's happening and how to fix it? I foresee I'll have the same problem trying to read the font name and size from the xml file. I have a workaround, but it's very unelegant. Here's the stack trace: System.ComponentModel.Win32Exception: Error creating window handle. at System.Windows.Forms.NativeWindow.CreateHandle(CreateParams cp) at System.Windows.Forms.Control.CreateHandle() at System.Windows.Forms.TextBoxBase.CreateHandle() at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible) at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible) at System.Windows.Forms.Control.CreateControl() at System.Windows.Forms.Control.WmShowWindow(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ScrollableControl.WndProc(Message& m) at System.Windows.Forms.ContainerControl.WndProc(Message& m) at System.Windows.Forms.Form.WmShowWindow(Message& m) at System.Windows.Forms.Form.WndProc(Message& m) at System.Windows.Forms.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.SafeNativeMethods.ShowWindow(HandleRef hWnd, Int32 nCmdShow) at System.Windows.Forms.Control.SetVisibleCore(Boolean value) at System.Windows.Forms.Form.SetVisibleCore(Boolean value) at System.Windows.Forms.Control.set_Visible(Boolean value) at System.Windows.Forms.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.Run(Form mainForm) at bindtest.Form1.Main() in d:\development\bindtest\form1.cs:line 109 tia, brian Tag: Scrollbar visual problem in a TreeView Tag: 65336

    - Panel Control Question I am stuck on something that must be simple. However, I have been searching the obvious places for several days but haven't come up with an answer: I have a Panel control with a custom designer. The designer creates several designer verbs. When a verb is selected, I want to instantiate a new Panel control on the 'base' Panel control, and allow the designer to edit the new Panel control (i.e., add other controls). The designer verbs work fine. However, if I simply use .Add to add a new Panel to the 'base' Panel the newly added Panel shows up on the UserControl but cannot be edited. On the other hand, if I simply drag a Panel control from the Toolbox to the 'base' Panel I can edit it--which is the behavior I want. The correct way to accomplish so it works this would be much appreciated! Tag: Scrollbar visual problem in a TreeView Tag: 65332

    - DataGrid/DataView Display problem I have a dataset table. I have filtered it and created a datview which I use as the datasource to a datagrid. That all works just fine. When I edit cells in the datagrid, then update the dataset table, the datagrid displays both the original row and the modified row. I only want to see the modified row. I have tried playing around with the DataViewRowState property. When I set it to ModifiedCurrent, no row is displayed. What am I doing wrong? Tag: Scrollbar visual problem in a TreeView Tag: 65331

Using VS 2003 ( C++ ), I've created a .NET Forms application. Added a TreeView docked to left, a Separator and a ListView docked to Fill ( not sure if relevant ). I've also enabled visual style using Application::EnableVisualStyles. The problem is that everything looks XP-ish ( I can see differences when I put the Name.exe.manifest to the same directory as the Name.exe ) except the TreeView's bottom scrollbar looks Win2k-ish ( even though no TreeViewNode exceeds the visible area of the TreeView ). When I expand the nodes until they go out of the TreeView visible area, the arrows from the scrollbar remain the same, while the center part of the scrollbar becomes XP blue-ish. If I collapse, the scrollbar dissapears ( as it should ). If I re-expand, the whole scrollbar looks as it should ( XP-ish )
Any ideas ?
