    - Using .ShowDialog with MDI Children ? Hi, We are trying to build a .NET MDI application with several child windows - some of which should be treated like dialogs and some as true child windows. We keep getting an error when we call Form.ShowDialog(Me) after having set the MDIParent property. Is it not possible in the .NET Framework 1.1 to use dialogs like that? thanks if anyone can help.

    - Tiling an image within a rectangle (GDI+) I'm trying to write a routine to tile a given image in a given rectangle: public static void DrawTiledImage(Graphics g, Image image, Rectangle r) { ImageAttributes ia = new ImageAttributes(); ia.SetWrapMode(WrapMode.Tile); g.DrawImage(image, r, 0, 0, image.Width, image.Height, GraphicsUnit.Pixel, ia); } Problem is this seems to be stretching the image not tiling it.

    - 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: Rotate Focus 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: Rotate Focus 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? I remember there is a method CloneMenu() in MainMenu class, but what is the correspoding method in MenuStrip class? Tag: Rotate Focus Tag: 96092

    - 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: Rotate Focus 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: Rotate Focus 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.

    - Deleting the last row of a DataGridView - focus? Hi, I have set a dataGridView to full row select. When deleting a row, the next one will be selected (whole row is highlighted). But when deleting the last row, I would expect the previous non deleted one be selected (whole row instead of just having the focus to one unique cell). Is this by design? If so, then I'll try to adapt to it. Otherwise, I'll try some code to select the whole row. Thanks Tag: Rotate Focus Tag: 96080

    - 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! Most times, I get the "Cannot start application" dialog with a msg "..the application is improperly formatted..." If I then click on "details" I see some messages such as the following: Activation of http://localhost/ClickOnceWebApp1/WebForm1.aspx resulted in exception. Following failure messages were detected: + Exception reading manifest from http://localhost/ClickOnceTest1/publish.htm: the manifest may not be valid or the file could not be opened. + Parsing and DOM creation of the manifest resulted in error.

    - 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: Rotate Focus 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?

    - 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.

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: Rotate Focus Tag: 96063

    - 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?

    - Visual Inheritance classic, but gets mixed up Hi, I'm using the following visual inheritance classic: base form with two buttons 'apply' and 'cancel' anchored to the bottom right corner. You inherit this base form and resize the inherited form, the buttons move along. At least most of the time, sometimes the buttons do not anchor to the borders of the inherited form but appear at a random other location on the form. A workaround is to remove the code this.ClientSize = new System.Drawing.Size(529, 312); from the inherited form and resize it in the designer to its original specs. Does a solution exist, instead of this workaround ? Best regards, Nico Tag: Rotate Focus Tag: 96011

    - Recent Files list - Is there a simple way? In my Windows Forma application, I would like to add a recent file list as part of a menu. I am thinking of adding an entry in registry whenever the user select a file and process it and then retrieve it back from registry. I also need to shorten the file name so that the menu's width will not be very large. This means some parsing codes. Since this functionality is very common, I am wondering is there a built in function or some simple code which can accomplish this? Appreciate your comments/suggestions.

    - How do I set form equal to nothing? Check this out: [VS 2005 .NET 2.0] Start a new project, drop a button on form1. Add a form (form2). In the button1 click event on form1, add the following... ....... If My.Forms.Form2 Is Nothing Then My.Forms.Form2.Show() End If ....... Taken directly from sample code. This will only run once and Form2 can never be shown again. I like the idea here, but how do I get it to behave correctly? Tag: Rotate Focus Tag: 95972

    - Dataview and XML nodes Hi, I am trying to populate a datagrid using XML but am running into some problems. As most tutorials show how to populate the datagrid that goes only one node deep, anything more then that and I can't figure it out. Currently I am doing pretty much trying to populate the datagrid "OrderGrid" with the "Orders" node from the XML. DataSet ds = new DataSet(); ds.ReadXml("data.xml"); DataView dv = new DataView(ds.Tables["Orders"] ); OrderGrid.DataSource = dv; The XML hierarchy looks like the following: <CustomerList> <Customers> <Orders> I want to basically in the end have a listbox that has the list of customers where anytime one were to click on a different customer int he listbox, the different order nodes would populate the datagrid. Currently, the datagrid has links to the four different rows which would then populate the differnet orders when clicked, but I'm not exactly sure what is going on except I think the different rows I am currently feeding the datagrid are each tables. Any help would be tremendously useful. Thanks! Tag: Rotate Focus Tag: 95971

    - Prevent tab page from changing I need to prevent user from changing a tab page, if the current tab page has incorrect data. I've been searching these forums for a solution and have found a suggestion that goes something like this: [StructLayout(LayoutKind.Sequential)] public struct NMHDR { public int hwndFrom; public int idFrom; public int code; } protected override void WndProc( ref Message m) { if ( m.Msg == 0x4e ) //WM_NOTIFY { NMHDR hdr = (NMHDR)Marshal.PtrToStructure(m.LParam, typeof(NMHDR)); if (hdr.code == -552) { ... m.Result = new IntPtr(1); } } base.WndProc(ref m); } However, this doesn't work for me. The tab page is still changed even though the m.Result is 1. Any ideas how to get this working? Is my WndProc in correct place, when it is in the MainForm (which owns the tab control)? Should it be somewhere else? Thank you. Tag: Rotate Focus Tag: 95970

How do I rotate focus among controls inside a groupbox/panel?

I have 10 controls in my form. Once the focus reaches control5 (using
my TAB key), I would like the focus to go to control1.

Thanks in advance

'Control.ActiveControl' + 'Control.SelectNextControl'.

Normally the focus move from control to control based on their tab order
(see TabIndex and TabStop) proeprties. By setting them correctly you can get
the desired effect without writing a code.

Me.Control5.Parent.SelectNextControl(Me.Control5, True, True, True,
True) in the Leave event sub worked like a charm.

Thanks Mr Wagner!
