Thanku so much. There is one more thing i want to ask. How can i make that login (mini) form (which just contains username, password field + two buttons) detached from the taskbar. I mean it should not be present on the taskbar. It should be dependent on the previous form. For example, have a look at this screenshot http://cs.gift.edu.pk/~tamour/form.jpg

Running on Windows Vista as a standard user? That's the UAC administrative password prompt, which runs on a secure desktop. That actually has a different wallpaper from your regular desktop, but to preserve the illusion Windows Vista makes a copy of the screen then dims it to use as the background. You might also see that password prompt, rather than the Confirm/Deny dialog, if your administrator has chosen that for administrative user elevations.
If your application actually requires administrative privileges to do what you're doing, then add a UAC manifest to set the requestedExecutionLevel to requireAdministrator. Windows will then prompt for administrative credentials to execute the program.
If instead you want to capture your own credentials, rather than Windows logon credentials, call CredUIPromptForCredentials. This won't do the 'secure desktop' thing. The only way I can see to do that is to call CredUIPromptForWindowsCredentials and use the CREDUIWIN_SECURE_PROMPT flag, but even that is called out as 'not supported' for Windows Vista. Must be new in Windows Server 2008.
An approach we've used before on Windows Mobile is to create a window that covers the entire screen and is topmost, but the user can still press Alt+Tab to switch away from it.

Hi i have an application that lists some screenshots into a form using a
listview with thumbnails.
I want to highlight (using a red rectangle or something) an area from the original screenshot,
but on the thumbnail.
Any idea how to do that?
(i need to somehow map coordonates from the original image to the thumbnail and then draw on it)
Thanks

Somehow? Just guessing here but try using Math.

Well - if you know the location on the original image, and the size of the thumbnail then I would suggest scaling it down by the same amount and putting it on the thumbnail at the same point (similarly scaled).

Hi murali,
I am not sure is this you want,but you may try it.In target method you can resize whatever you want.
this.SizeChanged += new EventHandler(target method);
Hope this help you

The simplest approach in .NET is to use the Dock and Anchor properties. If you want to create a toolbar, use the Dock property to place the toolbar at the top. Similarly a 'status bar' could be set to Dock at the bottom. That means that the control is attached to one side of the window, and its size in the other direction is the size of the window (i.e. if docked to the left, the horizontal size is maintained but the vertical size is the size of the window).
Controls within a window can also be Anchored to maintain a set distance from the edge of a window. The default is to anchor top and left, so that as the window is resized, the distances to the top of the window and to the left of the window are maintained. To have the control increase size to the right when the form is made larger horizontally (and shrink when the form shrinks), anchor to the right as well. Similarly you can anchor to the bottom.
To have a control which simply moves to the right and to the bottom, rather than resizing - for example, a button next to a single-line text box - anchor only to the right and bottom, turn left and top anchoring off.
For more complicated layouts, you can split your form up into Panels which can then be anchored, and you can anchor or dock your controls within the Panels. .NET 2.0 adds a FlowLayoutPanel and there is also a TableLayoutPanel for tabular layouts.

I have set the FormBorderStyle to None. But the problem I'm facing after setting it to none is that i cannot resize it. How can i make it resize able ?

The bold text thing is really annoying.
If you don't have a resize control, you need to make one. Capture the mouse when the user clicks, track it and resize your form.

Follow the Windows conventions. A window with no border is not resizable. Set the FormBorderStyle to Sizable.
This also governs the availability of the Size option in the window menu (press Alt+Space, left-click the icon, or right-click the window title or taskbar button).

Hi,
I am dealing with an windows application in which there is a form on which I m using DataGridView to display data fetched from the database.
I also used multi threading to show updated data continuously. Everything is working fine but I am not able to retain the DataGridView's scroll bar positions on successive execution of threads. How can i solve this problem?

Not sure if you get a callback from the API, but if you know the length of the track, can't you fudge it ?

Hi,
I am trying to open window form in designer (this form inherits another window form "BaseForm") ,
am getting exception and Visual studis is asking to debug or cancel message alert.
when I debugged and its said "Could not load file or assembly 'Wrappers.CLI,Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies.
The system cannot find the file specified."
The WSOD contains:
One or more errors encountered while loading the designer. The errors are listed below. Some errors can be fixed by rebuilding your project, while others may require code changes.
Could not load file or assembly 'Wrappers.CLI, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
Hide
at MyProject.BaseForm..ctor()
this is in C# project it has refernce to 'Wrappers.CLI' dll.
I tried
1. rebuilding
2. steps in http://www.codeproject.com/KB/cs/wsod.aspx[^]
but none was working..
Thanks,
Ramki

Hi, visual studio creates a design time cache of your objects. try shutting down the ide (close all file & design views first), then deleting all the folders at C:\Documents and Settings\<user name="">\Local Settings\Application Data\Microsoft\VisualStudio\9.0\ProjectAssemblies
then rebuild. the 9.0 folder is for vs2008, vs2005 will be 8.0
Hope this works, Rob
