    - Me.Invoke - Incorrect behavior I have encountered an odd behavior when using Me.Invoke and any help would be great. I am using a standard Me.InvokeRequired followed be a Me.Invoke to make sure a method runs on the UI thread. This logic has worked for me countless times but for some reason I have a problem with it in one circumstance. The Me.Invoke is called but it does not create the delegate on the UI thread. Instead it creates the delegate on the same thread which then gets caught by the Me.InvokeRequired which call Me.Invoke and this continues until I get a stack overflow. So my question is what would cause Me.Invoke to not use the UI thread but instead the thread that it is currently on? Below is a code snippet.... Private Delegate Sub SetButtonDelegate(ByVal Value As Boolean) Private Sub SetButton(ByVal Value As Boolean) If Me.InvokeRequired Then Dim newDelegate As New SetButtonDelegate(AddressOf SetButton) Me.Invoke(newDelegate, New Object() {Value}) Else Mylabel.Enabled = Value Mybutton.Enabled = Value End If End Sub Thanks Madison -- Madison Decker - MCSD Tag: Smart Client failures Tag: 96153

    - Skinnable UI with WinForms Hello Everyone, I have a requirement of writing a WinForm application that should support "SKINS" for the UI. On applying a skin, the look and feel of the application can change drastically. Even the size and shape of the Main window and its child controls can change. I have NO idea about, how to achieve this in .NET WinForms. Any Article, Link, Sample or Lecture will be greatly appriciated with Tons of Thanks :-) Thanks * (Vipul) () ; =================================== Vipul Pathak, Indore, MP, India.

    - Child forms Hi, When running this code, it's not possible to select the text using the mouse in the textbox. What's wrong with it? (This is just a code snippet. I can't use a MDI frame).

    - control validation problem I have create a control which CauseValidation=true (let's call it ValidatingControl) I have created another control reacting to user action.(let's call it GuiControl) Now my problem is: If my ValidatingControl is not valid and I click on some other gui element, such as a CheckBox or the close button of my window, nothing happen: which is fine and expected. But if I click on my GuiControl it react on user input as usual, regardless of the fact my ValidatingControl is not valid. So the question is: how do I check in my GuiControl wether or not I'm allowed to react to user input (i.e. that there are no pending validation)? -- Regards, Lloyd Dupont NovaMind development team NovaMind Software Mind Mapping Software <www.nova-mind.com> Tag: Smart Client failures Tag: 96122

    - Round edge panel: edges not smooth I am creating a round edge panel by inheriting from the panel. What I do is create a graphics path with desired shape and in the Paint method I fill the graphics path and draw the graphics path border with desired color. This would look as if the panel has round edges. So far I have not set the region. Bounds of the panel is still the rectangle. But the problem come when I set the region of the panel to the Graphics path region. It would not draw the borders( especially left and bottom) properly, it would not draw the curves properly. Also if I set the background image , the image is not smooth along the borders even though I set smoothing mode to AntiAliasing . Any ideas on why it is behaving this way would be greately appreciated. Here is the code in Paint method protected override void OnPaint(System.Windows.Forms.PaintEventArgs e) { Graphics gr = e.Graphics; gr.SmoothingMode = SmoothingMode.AntiAlias; if(_roundedCorners) { // clear background with the parent's backcolor before drawing the round edges gr.Clear(Parent.BackColor); gr.DrawPath(_borderPen, _roundedEdge); // now fill with actual color gr.FillPath( _graphicsPathBrush,_roundedEdge); // setting the region of the control this.Region = new Region( _roundedEdge); // this is where the problem comes } } Here is the method where I create the path protected void CreatePaths() { // Create _roundedEdge _roundedEdge = new GraphicsPath(); _roundedEdge.AddLine(_topLeftEdgeRadius, 0, Width - _topRightEdgeRadius - 1, 0); _roundedEdge.AddArc(Width - _topRightEdgeRadius - 1 - _topRightEdgeRadius, _topRightEdgeRadius - _topRightEdgeRadius, 2 *_topRightEdgeRadius, 2 *_topRightEdgeRadius, -90, 90); _roundedEdge.AddLine(Width - 1, _topRightEdgeRadius, Width - 1, Height - _bottomRightEdgeRadius - 1); _roundedEdge.AddArc(Width - _bottomRightEdgeRadius - 1 - _bottomRightEdgeRadius, Height - _bottomRightEdgeRadius - 1 - _bottomRightEdgeRadius, 2 *_bottomRightEdgeRadius, 2 *_bottomRightEdgeRadius, 0, 90); _roundedEdge.AddLine(Width - _bottomRightEdgeRadius - 1, Height - 1, _bottomLeftEdgeRadius,Height - 1); _roundedEdge.AddArc(0, Height - _bottomLeftEdgeRadius - 1 - _bottomLeftEdgeRadius, 2 *_bottomLeftEdgeRadius, 2 *_bottomLeftEdgeRadius, 90, 90); _roundedEdge.AddLine(0,Height - _bottomLeftEdgeRadius - 1, 0, _topLeftEdgeRadius); _roundedEdge.AddArc(0, 0, 2 *_topLeftEdgeRadius, 2 *_topLeftEdgeRadius, 180, 90); } Thanks, VPMahank.

    - Strange behaviour of Form.WindowState.Maximized in Form.Activate event Hi, I am experiencing problem with changing the Form.WindowState property of the Child form in the MDI Winform Application. If I change the 'WindowState' property to 'Form.WindowState.Maximized ' in the Form Activate event of the MDI child form I will get double Control/System menu box for this form. By closing the form there is Control/System menu box left behind. If I repeat the process the number of Control/System menu boxes grows. I am expecting that each form can have only one Control/System menu box. Is this a defect or did I forget to take something into account? Is there known hot fix for this behaviour e.g. another way to maximise MDI child form in Activate Event? I am using VS 2003, .NET 1.1 with SP1, PC is W2K with SP4. Please see my demo below. Thanks Viliam Batka PS: Regardless of unexpected visual effect it can indicates possible memory leak. //=DEMO============================================== // Description: // *Demo for Strange behaviour of FormWindowState.Maximized // in Form.Activate event. // *This C# example is possible to compile as console application // with references to System.Windows.Forms. // Author: Viliam Batka using System; using System.Windows.Forms; namespace ViliamBatka.MdiTest { class MDI_Test { [STAThread] static void Main(string[] args) { // create MDI main form Form fMDI = new Form(); fMDI.Activated += new System.EventHandler(OpenMultipleChildren); fMDI.IsMdiContainer=true; Application.Run(fMDI); } // open multiple MDI childer static void OpenMultipleChildren(Object sender, System.EventArgs e) { for (int i=1;i<10;i++) { Form fChild = new Form(); // add event handler fChild.Activated += new System.EventHandler(Child_Activated); fChild.MdiParent = (Form)sender; fChild.Show(); fChild.WindowState = FormWindowState.Normal; } Form f = (Form)sender; f.WindowState = FormWindowState.Maximized; } // maximize Child Form at Activate event static void Child_Activated(Object sender, System.EventArgs e) { Form f = (Form)sender; f.WindowState = FormWindowState.Maximized; } } } //=END DEMO========================================= Tag: Smart Client failures Tag: 96117

    - Problem with CenterParent property Hi All, I have a windows application that has a form that gets sized based on the content of a rich text control. I've set the StartPosition of the form to CenterParent. In design mode the form is about 700 pixels wide. I've handled the SizeChanged event of the richtextbox to set the width of the form. Now the problem I'm facing is that when the form is displayed for the first time the left/top position is calculated on the basis of the original dimensions of the form and not the changed ones. Due to this it does not appear centered in the parent form, though .NET thinks that it positioned the form in the center as it is used the original dimensions to calculate the left/top position. After dismissing the form and opening it again will correctly center it within the parent form, because the width got changed the first time and now the CenterParent is calculated properly. But I want it centered the first time round and everytime. Thanks in advance. SK Tag: Smart Client failures Tag: 96100

    - How to use MaskBlt operation in GDI+ Hi, I want to copy some portion of a bitmap(source bitmap) to another bitmap(destination bitmap) using a reference mask bitmap. This task can be acomplished in GDI using MaskBlt function. Is there any such function in GDI+ for doing the same? I saw Bob's "Extract a region from a bitmap" article. In that we are creating region based on the given color and setting it as the region for the form. But in my case, I have the reference mask bitmap. If a particular pixel in the mask bitmap is "WHITE", the corresponding pixel value available in the source bitmap should be copied to destination bitmap. Otherwise, it should be ignored. This process sould be repeated for the entire image. If anyone knows, kindly update. Tag: Smart Client failures Tag: 96098

    - how to clone a menustrip? I have to implement a function that pop up a context menu which is the same as the main menustrip in the form. but when I create the context menu using the items of the main menustrip, I found that those items are snatched from the menustrip by context menu. For example: ContextMenuStrip.Items.AddRange(MenuStrip.Items); so I think I have to clone the items for context menu. How to do it?

    - WebBrowser control and AddFontMemResourceEx Not exactly a Windows Forms question, but I failed to find a more suitable group. What I'm trying to accomplish is to enable custom fonts (likely embedded into my application as a resource) in the WebBrowser control (2.0). It works just great to add fonts using AddFontResourceEx, providing a path to the font file in question, but because of both legal and technical reasons I would prefer to be able to only just add the font in memory, from an (encrypted) embedded resource. Must the WebBrowser control (Internet Explorer) be able to enumerate the fonts or is there another reason AddFontResourceEx works when AddFontMemResourceEx doesn't? Perhaps there is another way of accomplishing this? WEFT fonts would be OK if there was a way to create them programatically, I guess. /Gunnar Tag: Smart Client failures Tag: 96091

    - ListView, Removing items. I'm having an issue with ListView control. THe list view contains items that are dynamically added and removed at run time. The problem comes when I try to remove an item. Whenever an item is removed, the ListView seems to automagically 'select' the item which sits in the same spot the recently removed item did. This only causes a problem when removing the last element in the Items collection, because there is no element to select, so it throws an index out of bounds exception. Anyone know how to stop it autoselecting an item after a removal? Cheers, Tim Tag: Smart Client failures Tag: 96084

I have tried saving it to both a png and a gif format and loading them into an image list and reference that for toolbar button images. In either case whenever i display it in the image is rendered with blue swiggles/distortions around it. I believe this is because of the transparancy as the image displays fine in a webpage.

    - ClickOnce via Response.Redirect I can use a ClickOnce app I made fine, but I cannot seem to reliably access it via an asp.net app that redirects to it: I created a simple ClickOnce windows forms application in VS 2005 that deploys via IIS; that works fine when either type in the URL, for example "http://localhost/ClickOnceTest1//ClickOnceTest1.application", or hit the autogenerated publish.htm URL. Buuuut...if I then make a new, separate asp.net web application (using vs 2003, so .net 1.1), (let's say it's called ClickOnceWebApp1) and simply call Response.Redirect("http://localhost/ClickOnceTest1/ClickOnceTest1.application",true), it generally does not work - once in a while, it works fine!

    - MenuStrip merging I want to merge a MenuStrip with the MainMenuStrip of an MDI container form. I would like this newly merged menu to be the default menu in which MDI children will automatically merge their menus with when they are activated (which is the default documented behavior of MDI children). What is the best way to achieve this? I added an initial call to ToolStripManager.Merge() in the constructor of my MDI container form after InitializeComponents() to perform the first merge of the main menu strip. Whenever a child MDI form is activated, the aforementioned merge is automatically reverted back before the MDI child menu strip is automatically merged. Then, whenever the child is deactivated, the mainMenu reverts back to its initial state before any merges. It appears that you cannot compound multiple merges with a single menu. I believe that ToolStripManager.Merge() calls ToolStripManager.RevertMerge() before the requested merge is performed. Is there a way to persist the initial merge to where it will not be reverted whenever a child is activated? I thought perhaps I should clone a new menu from the initial merged menu and assign that as the MainMenuStrip of the MDI container before any child MDI containers are created and activated. But, cloning a menu strip does not appear to be a trivial task as windows forms do not implement IClonable. Tag: Smart Client failures Tag: 96070

    - WinForms Smart Client app unable to access contents of config file I have a simple WinForms app which uses values from the appSetting section of the config file. When the exe is invoked directly, thes values are retrieved as expected. When I try to launch the app vi Internet Explorer, however, it seems that the appSettings collection i empty. A reference in the for ConfigurationSettings.AppSettings["keyname"] returns null; a call t AppSettingsReader.GetValue() throws an exception ("The key 'keyname does not exist in the appSettings configuration section"). I have followed the advice given by Chris Sells and others: - I have enabled anonymous access to the directory containing the ex and config file. - I have added a web.config file to the same directory with an entr allowing *.exe.config files to be downloaded. With this in place, the config file is indeed downloaded: - If I request the config file directly in Internet Explorer, it i returned. (Visual Studio opens to display it.) - If I clear out the Assembly Download Cache and my Temporar Internet Files before attempting to run the application via Interne Explorer, I see the following in the IIS Log: 17:40:21 127.0.0.1 GET /ND_Client/ND_Client.exe 200 17:40:21 127.0.0.1 GET /ND_Client/ND_Client.exe.config 200 17:40:26 127.0.0.1 GET /ND_Client/ND_Client.exe.config 304 17:40:26 127.0.0.1 GET /ND_Client/ND_Client.exe 304 17:40:27 127.0.0.1 GET /ND_Client/en-GB/mscorlib.resources.DLL 404 [plus more requests for non-existent files] If I then look in my Temporary Internet Files directory, I can see bot the exe and the config file. However, if I look in the Assembly Downloa Cache, I see only one file, which the timestamp identifies as the exe (Should I expect to see the config file there? If not, where would th runtime find it?) It therefore seems that the problem is on the client side. What else d I need to do?

I can add an image to each ToolStripMenuItem, but when I attempt to set the ImageTransparentColor property, I'm getting an exception. Here is the code that is causing the problem: menuItem = new ToolStripMenuItem(ContextMenuItemsText[(int)item]); menuItem.DisplayStyle = ToolStripItemDisplayStyle.ImageAndText; menuItem.Click += new System.EventHandler(menuItem_ContextMenu_Item_Click); menuItem.Image = new Bitmap(@"C:\temp\Copy.bmp"); menuItem.ImageScaling = ToolStripItemImageScaling.SizeToFit; menuItem.ImageTransparentColor = Color.FromArgb(254, 1, 254); When I run the code, the following exception is thrown: System.OutOfMemoryException: Out of memory. at System.Drawing.Graphics.CheckErrorStatus(Int32 status) at System.Drawing.Graphics.DrawImage(Image image, Rectangle destRect, Int32 srcX, Int32 srcY, Int32 srcWidth, Int32 srcHeight, GraphicsUnit srcUnit, ImageAttributes imageAttrs, DrawImageAbort callback, IntPtr callbackData) at System.Drawing.Bitmap.MakeTransparent(Color transparentColor) at System.Windows.Forms.ToolStripItem.set_Image(Image value) ... Does anybody know why this would be? What can I do to set the transparency color of the images in the context menu? Thanks, Dan Tag: Smart Client failures Tag: 96067

    - DataGridView.ReadOnly property modifies DataGridViewColumn.ReadOnl The MSDN documentation makes it sound like the ReadOnly properties of the DataGridView, the DataGridViewRow, and the DataGridViewColumn can be set indepently and that a: Quote: Cell is read-only if the value of the ReadOnly property is true for the cell, the cell's row, the cell's column, or the DataGridView. The problem I am facing is that if you toggle the ReadOnly property of the DataGridView it modifies the DataGridViewColumns ReadOnly properties. It really should not do this. The use case where this is annoying is if you have a set of columns that are always read-only but you need to temporarily disable all cells in the grid. In this case you set the ReadOnly property of the DataGridView to true and when the user can edit it again you set it back to false. Setting it back to false causes you to loose all the column ReadOnly properties. Is there a way around this? I really do not want to reapply the readonly properties to the columns all the time.

    - Datagrid error handling Hi all. When the update method of my data adaptor raises an exception it causes my bound datagrid to display an error icon next to the offending row with an appropriate error tooltip. This is exactly what I want. However, I also want to focus the cell/row causing the problem. How can I determine which row in the grid caused the error? The grid seems to know exactly which one it was as it displays the error icon on the correct row, but how can I determine this programmatically? TIA. John. Tag: Smart Client failures Tag: 96063

    - ClickOnce Memory Leak Hi, Has anyone noticed a memory leak when using the ClickOnce API calls. Each time I call the CheckForUpdates method, my application's memory increases my 300K. This memory is only released when the application stops I think that it's a bug within the System.Deployment.Application assemble Regards, James Tag: Smart Client failures Tag: 96057

    - Problem with PropertyGrid and DateTimePicker Hi I have a problem using a DateTime or Date value in the propertygrid in VS 2003 in a VB.net project. I have displayed an object in the PropertyGrid that has a DateTime value. When the property is clicked in the PropertyGrid the DateTimePicker is displayed with the correct value. However if the Year is clicked and the value is moved backwards in time using the UpDown control provided the display of dates for the month is incorrect. I have seen this behaviour in the VS IDE as well as in a form I have built. The DateTimePicker works correctly if it is embedded on a Windows Form. Does anybody know what is wrong or is aware of a getround. The problem is easy to reproduce: Start a new Windows application Create a basic class with a DateTime property apply an instance of the class to the propertygrid click the down arrow and go backwards in the years If have not tested this in c# Regards Paul Tag: Smart Client failures Tag: 96054

    - DataGridView changes column visibility If you create a DataGridView and add a hidden column to it (a column with its visible property set to false), the DataGridView will make the column visible anyway if you make changes to the data source. For an example of this behavior, crate a new windows form project and place a DataGridView control on the form. Add this one line of code to the form class: private DataTable dt; Put the following code in the Load event for the form: // primary key column DataGridViewTextBoxColumn column = new DataGridViewTextBoxColumn(); column.DataPropertyName = "primarykey"; column.HeaderText = "primarykey"; column.Visible = false; dataGridView1.Columns.Add(column); // value column column = new DataGridViewTextBoxColumn(); column.DataPropertyName = "value"; column.HeaderText = "value"; column.Visible = true; dataGridView1.Columns.Add(column); // create DataTable and set as the DataGridView's DataSource dt = new DataTable(); dt.Columns.Add(new DataColumn("primarykey",typeof(int))); dt.Columns.Add(new DataColumn("value", typeof(string))); dataGridView1.DataSource = dt; If you run the project, everything will look good. Now, put a button on the form and add the following code to its click event: dataGridView1.DataSource = null; dataGridView1.DataSource = dt; Now run the program. When you click on the button, suddenly the invisible column becomes visible. This doesnâ??t just happen when you change the datasource, but also happens if the data source is a DataView and you filter the records, etc. Has anyone else encountered this and does anyone know if there is a fix for it?
