    - DLL References (New developer) I have two projects. Project A and Project B. In project A I have added Reference of Project B. And in Project B I have added Reference of Project A. It was not possible in framework prior to Framework 2.0. It works great for me. My question is, is it ok to add reference like this. Is this against any programing standard. Please give me some suggestion or advices, as I am very new to software development. Thanks Green Tag: ShowDialog has own taskbar button Tag: 94149

    - Visual Inheritance Hi, I would like to put on all my Forms a BackgroundImage. Because it is the same one I want to use Visual Inheritance. I am not sure why I have to create a DLL-Library for my base Form in VS2005, but this is what I did. So somewhere in my base form I want to load the image, which should be a relative path from Application.StartupPath. Since I find myself in a DLL-Library I have no access to Application.StartupPath. My next thought was okay then I make my base class abstract (mustinherit) and force the derived class to set the path with a mustoverride method. Unfortunately I cannot set this class to mustinherit, because the Designer has problems to create the form. Can somebody tell me what is the best way would be to solve this.

    - Drag Form without border I am writing a WinForms app that can be used, if wanted, on a touch screen. When used in this manned, I supply an on-screen keyboward to enter data. I want to display the keyboard form borderless and also allow the user to drag it around the screen. I have a dedicated button on the form to use to drag the form but for the life of me can't figure out how to actually drag the form when the user touches the button and keeps it pressed and drags. Suggestions anyone? Tag: ShowDialog has own taskbar button Tag: 94143

    - Transforming Controls? Hi, I'm trying to draw a standard windows forms control onto a form with a transformation. Before drawing the control I'm applying a world transformation to the graphics object, but the results seem to be unpredictable. Depending on the control my transformation seems to be applied incompletely. For example, buttons are translated as I'd expect but not scaled or rotated. The easiest way to demonstrate this is to extend Bob Powell's excellent animation demo from http://www.bobpowell.net/animation.htm To see what I mean, add this class to Form1.cs in the demo: public class ButtonShape : Shape { private class MyButton : Button { public void Draw(Graphics g) { PaintEventArgs args = new PaintEventArgs(g, new Rectangle(0, 0, Width, Height)); base.OnPaintBackground(args); base.OnPaint(args); } } private MyButton mb = new MyButton(); public override void RenderObject(Graphics g) { mb.Draw(g); } } And modify the Form1 contstructor to add some ButtonShapes: switch(r.Next(4)) { // ... snip .... case 3: s = new ButtonShape(); break; // ... } After making these modifications I get some buttons floating around with the other shapes, but they do not rotate as the others do. Anyone have any suggestions? Is it just not possible to apply a transformation to a control because of the way they are drawn?

    - hide datagrid column .net 2.0 I am using c# express RTM. I have a datagrid with attached to a dataset. I have set the primary key (identity seed) column's visible proeprty to false. The column is hidden in design view but when I run the form it appears. Not sure if this is a bug, or if because the field is a primary key field with an identity seed it cannot be hidden. Another question, how can I set the default value of a column to the identity field of the parent form? The datagrid is in a parent-child relationship.

    - Keeping a form on top of its application I'm trying to keep a form on top of all other windows in its own application, but not on top of all windows in all applications. I can get it to be on top of all applications by setting "TopMost = true", but can't get it to only be on top of its own application (i.e. when I select another application the form I've made TopMost is still on top of everything). I've tried setting the MdiParent to be the application, but then the "TopMost" property seems to have no effect (the code I was using for this is shown below). DebugControl debugCtrl = new DebugControl(); debugCtrl.MdiParent = this; debugCtrl.TopMost = true; debugCtrl.Show(); Has anyone any idea how I can do this?

    - Hosted Winforms control in Internet Explorer Hi All, I've got a WinForms control that I host in IE to allow certain people to upload a directory structure to my Intranet. The control is signed, strongly named and the web site it's running from is Trusted and Trusted sites have been given full permissions in the .Net configuration tool. It works perfectly if I only have Framework 1.1 installed, as soon as I install 2.0 - it stops working entirely, the placeholder on the page never disappears. It's the same behaviour that I get when I try and run it from a non-trusted sites, but I've made sure that it's setup in 1.1 and 2.0 I've tried it on my bosses machine so he doesn't have Visual Studio installed and it's the same, install 2.0 it stops working, uninstall 2.0 and it starts working again. Any ideas please ? Tag: ShowDialog has own taskbar button Tag: 94113

    - Text looks bold when i manually double buffer to a bitmap Hi Thanks for taking the time to read this post and offering any suggestions/advice. I have an owner drawn control that uses the standard setstyle method to double buffer my painting. Everything works fine and looks as intended. I am now in the process of expanded my rendering class to support internal scrollable sections. I decided to do this by creating a wrapper class to handle the painting. The wrapper class creates a new bitmap and passes the graphics object from it to the original paint event of the renderer. It then works out what section of the paint needs to be blitted onto the real canvas and does so using the drawimage method. It all works great apart from any text that is rendered to the new bitmap looks really bad. It almost looks like it is bold but it is also nowhere near as smooth as a bold font would be. I believe I have ruled this down to the new bitmap being created with a transparent background using black pixels. If I change the background to white using the setpixel method and make it transparent using this colour (a straight fillrectangle and anything other than white does not work) then everything looks like it should. Obviously this is a very slow method and totally unacceptable in the final product. Can anyone shed any light on the standard practice used to eliminate such problems? My current code in the paint method of the scrolling wrapper class is as follows .... 'create canvas for child to paint on. we will extract the applicable portion of the 'canvas and blit the render to the passed graphics object Dim canvas As New System.Drawing.Bitmap(rect.Left + rect.Width, rect.Top + h) canvas.SetResolution(g.DpiX, g.DpiY) Dim gphcs As System.Drawing.Graphics = System.Drawing.Graphics.FromImage(canvas) Dim rect2 As New System.Drawing.Rectangle(rect.Left, rect.Top, canvas.Width, canvas.Height) Dim srcRect As New System.Drawing.Rectangle((rect.Left + _XOffset), (rect.Top + _YOffset), rect.Width, rect.Height) '***** this is the bit that corrects the problem, but it is very slow ***** 'Dim x, y As Integer 'For x = srcRect.Left To srcRect.Right - 1 Step 1 ' For y = srcRect.Top To srcRect.Bottom - 1 Step 1 ' canvas.SetPixel(x, y, System.Drawing.Color.White) ' Next 'Next 'canvas.MakeTransparent(System.Drawing.Color.White) _renderer.Paint(cp, gphcs, rect2) g.DrawImage(canvas, rect, srcRect, Drawing.GraphicsUnit.Pixel) gphcs.Dispose() canvas.Dispose() Tag: ShowDialog has own taskbar button Tag: 94108

    - Alpha blended, Double buffered non-client areas. How? Please help! Hi, I am deriving from Panel and I paint the client and non-client area of the panel myself. I am drawing a bitmap in both the client and non-client area. The bitmap has an alpha channel so the edges are neatly anti-aliased. I am using the WM_NC* messages to distinquish between the client and non-client area. I set the ControlStyles to both OptimizedDoubleBuffered and SupportTransparentBackColor and set the BackColor to a transparent color. All of this works fine, except for the fact that the non-client area does not use double buffering or transparency. It seems that the control styles are used for the client area only? I have read Bob Powell's faq on Windows Forms and he also has a section on transparent forms. However, if you set the WS_EX_TRANSPARENT style, you will never be able to use double buffering, since Bob's technique will invalidate the parent's window, causing flickering. Microsoft's approach for copying the parent's background into an offscreen surface, and then copying your own graphics over it sounds like the only possible way to deal with double buffered transparent controls. The frustrating thing is that .NET has everything in place with the background painting. I've checked reflector and OnPaintBackground indeed paints a piece of the parent control into the graphics object, when SupportTransparentBackColor is set and the backcolor alpha is not opaque. Great, but it seems that OnPaintBackground only paints the client area and not the non-client area... Did I miss something? Bottom line is: does anybody know how to handle double buffered, transparent, alpha blended non-client area's? I'm counting on you, Bob :).

    - propertyGrid display filedialogbox Hello all, I am trying to use a propertyGrid control which will display custom made properties. I have therefore created a class (properties.vb) that i have assigned to the propertyGrid.selectedObject property and that keeps the properties that i want to display. What i am trying to accomplish is the following: I'd like to have a property (in the propertyGrid) that when clicked it would open an openfiledialog box (like the one that is used when we select an image for a control) but i want it to be able to select any type of file. A second thing is that i want to have a property that would be a collection so when the ellipsis (...) is clicked an add/remove collection items box is shown. This is easy to do (declare the public property to be of collection type). But i'd like ,when pressing the Add button (on the add/remove collection items box) an openfiledialog box to appear and the item selected to be added to the collection. It would also be great if i could create the properties that appear on the right side of the add/remove collection items box.

    - Getting NullReferenceException setting ReadOnly property of a DataGridViewCell Using .NET 2.0 Release: I get the subject exception when performing the following sequence of events. 1. I manually select a cell in a DataGridView. 2. via a ComboBox I change the cell's column's state to ReadOnly=False. 3. this causes the selected cell to enter edit mode because I've set the grid's edit mode to EditOnEnter (which is the mode I want to use). 4. Before anything is seen I handle the CellFormatting event where I color and set the ReadOnly property of cells base on their value and other cell values in the row.

    - Getting Caret Position from another process Does anyone know how I can get the caret position in terms of screen position from the currently active window? By currently active window I don't mean just mine, rather any window. Basically the end result I want is to position a floating tooltip style window next to wherever the user is typing (their caret) regardless of what app they are using. I've tried calling GetCaretPos, however this only seems to work when my app currently has the focus. At all other times the POINT returned by GetCaretPos is 0,0. I think this is due to other windows destroying their Carets when they lose the focus. Does any smart cookies out there have any ideas? Tag: ShowDialog has own taskbar button Tag: 94063

    - Exporting data, how to set output order, ala View Tab Order My app has to export data from SQL Server tables, along with other data (data about the data being exported) into a text file. I have several checkboxes on my VB.NET 2003 Winform, which allows the user to select wether or not to export that peice of data, ie, Export Sum Total. I also have a user control that allows the user to select SQL Server columns in one list box and move them to a "selected columns" listbox. This allows selection of the data from the SQL Tables to export. I need to be able to allow the user to select the order in which the items should be exported to the text file. I was thinking about some mechansim similar to Visual Studio's UI where you can set the tab order of the controls on the form. Any ideas, solutions, sample projects would be greatly appreciated.

Can anyone see what I cant? public static Cursor LoadCursor (string CursorName) { Cursor myCursor = null; String Name; IntPtr HCursor=IntPtr.Zero, HInst=IntPtr.Zero; //Name = "Prologic." + CursorName + ".CUR"; Name = "ProLogic.Cursors.IRON.CUR"; HInst = Win32.GetModuleHandleW(null); HCursor = Win32.LoadImage(HInst, Name, Win32.IMAGE_CURSOR, 0, 0, Win32.LR_DEFAULTCOLOR | Win32.LR_DEFAULTSIZE | Win32.LR_SHARED); //HCursor = Win32.LoadCursor (HInst, Name); if (HCursor.ToInt32() > 0) myCursor = new Cursor (HCursor); return (myCursor); } } /// <author>Shrijeet Nair</author> public class Win32 { public const uint IMAGE_BITMAP = 0; public const uint IMAGE_ICON = 1; public const uint IMAGE_CURSOR = 2; public const uint LR_DEFAULTCOLOR = 0x0000; public const uint LR_MONOCHROME = 0x0001; public const uint LR_COLOR = 0x0002; public const uint LR_COPYRETURNORG = 0x0004; public const uint LR_COPYDELETEORG = 0x0008; public const uint LR_LOADFROMFILE = 0x0010; public const uint LR_LOADTRANSPARENT = 0x0020; public const uint LR_DEFAULTSIZE = 0x0040; public const uint LR_VGACOLOR = 0x0080; public const uint LR_LOADMAP3DCOLORS = 0x1000; public const uint LR_CREATEDIBSECTION = 0x2000; public const uint LR_COPYFROMRESOURCE = 0x4000; public const uint LR_SHARED = 0x8000; [DllImport("User32.dll")] public static extern IntPtr LoadImage(IntPtr hinst, [MarshalAs(UnmanagedType.LPTStr)] string lpszName, uint uType, int cxDesired, int cyDesired, uint fuLoad); [DllImport("User32.dll")] public static extern IntPtr LoadCursor(IntPtr hinst, [MarshalAs(UnmanagedType.LPTStr)] string lpszName); [DllImport( "kernel32.dll" )] public extern static IntPtr GetModuleHandleW([MarshalAs(UnmanagedType.LPStr)] string lpModuleName ); } Thanks for any help.

    - Activate multiple windows? I have an app with two windows, neither is shown modally. One is a main window, one is a tool window. The main window is being shown by Application.Run(). The tool window is subsequently shown by Show(). When I minimize the main window, the tool window disappears. The tool window is by design, not shown in the taskbar. What I want is to have the tool window (As well as any subsequent tool windows) activated when the main window is activated, but not draw focus away from the main window. Can anyone lend some insight on this? If you've ever used Microangelo, this should give some idea of what I want to do. -- Any help is appreciated. Thanks in advance.

    - Send Keyboard messages from one window to another? I have an app with two windows, neither is shown modally. One is a main window, one is a tool window. My main window has several menus on it. What I want is when someone uses the keyboard on the tool window, for the message to get sent to the main window. If someone types Ctrl+O on the tool window, I want the main window to process it and show its Open Dialog, etc. I have a reference to the main window inside the tool window and vice versa.

    - MDI layout problem Hi I need to build a windows application with a main window which has on the left side an area with fixed controls and on the right side an area which serves as parent container for MDI childs. If I simply set IsMdiContainer=true on the form, the MDI childs will be partly hidden by the GroupBox on the left which contains the fixed controls. As far as I understand (sorry I am a .NET newbie) only a Form can be a MDIContainer and there can be no forms within forms (right?). So what would be the best way to solve this problem? Thanks, Hans Tag: ShowDialog has own taskbar button Tag: 94033

    - Form resizing problems (HELP!) So, I have the following setup: * A form which is fullscreen (let's say 800x600) - Containing one PictureBox the size of the form's client area * Another form (details not important) The fullscreen form's PictureBox gets a snapshot (WM_PRINT) of 'Another form'. Then it rotates the image 90deg clockwise and displays it in it's PictureBox. Mouseevents received by the PictureBox are sent (with co-ordinates translated) to 'Another Form'. All of this is fine, until I want to make 'Another Form' 600x800, in order for it to display 'fullscreen' when it is rotated. The problem I have is that I can't force 'Another Form's size to what is effectively bigger than the desktop. The best I can get is a 600x600 (or whatever). I can change just about anything here, so any ideas welcome... Jamie Tag: ShowDialog has own taskbar button Tag: 94028

    - Flexible data grids I'm looking for a type datagrid control that will allow me to have more flexibility in the layout of each record that I display. So, similar to a continuous form in Access, I can have multiple text boxes for each, so increasing the height of each 'row'. I've just installed VS 2005 and, at first look, it still doesn't seem to be a feature of the datagridview. (Am I right there, or is there now some way of doing it?) If it's not available in the standard package, then does anyone have any recomendations on a good third party control? The ability to change the layout as described is the key thing I'm looking for, but something that ironed out some of the other quirks and limitations of the datagrid would also be nice. Thanks for any suggestions. Tag: ShowDialog has own taskbar button Tag: 94024

    - datagrid current row Gday, Am new to using datagrids so if anyone could assist or point in the right direction in terms of resources - that would be much appreciated... I have a form that has: - a datagrid that displays summary data - other controls (eg textboxes, comboboxes) that are editable What I would like is when a use selects a row in the datagrid that the all corresponding fields for that row of data shows up in the other controls from where they can be edited. I dont like the idea of depending on the datagrid position attribute to return the selected row, as I would like to allow the datagrid to be able to be sorted on any column - hence the position would appear to be useless...unless you changed the form's dataview everytime the datagrid gets re-sorted? I believe what I need to do is get the key of selected row in the datagrid and use this to synchronise the data that is getting displayed on the rest of the form but am not sure of how to go about this... If there are alternatives I would love to hear them. Regards, Peter Tag: ShowDialog has own taskbar button Tag: 94021

    - MessageBox (or equiv) while background thread completing long operation. I have a windows forms application (.net 1.1) and I want to have a msgbox like window blocking the main thread while a long operation completes in a background thread. Is there a way to do this using MessageBox.Show() and somehow closing it from the other thread? Or will I need to make a basic form and have an event on it to do a this.close() from the other thread? Something entirely different? Sorry if this is a repeat, the terms are fairly ambiguous so I couldn't google much. Lloyd Christopher SLOW30 Tag: ShowDialog has own taskbar button Tag: 94013

Hi all,

Why is it that when I create a new windows form and show it in my
application it has it's own taskbar button?

Is there a way around this?

Set the form's 'ShowInTaskbar' property to 'False'.
