That's real experience speaking there. Damn, you and your years of coping with subtle problems like this.

1st read the error message, it will contain clues as to what you have done wrong.
2nd, Google for the error message, other people may have asked about it before so you might find clues.
3rd, when and only when you have done both of the above, if you are still stuck, post the full error message displayed, and the line of code that it says causes the error and we'll try to help.

I have a treeview control whose particular node needs to be dynamically selected during page load. Kindly let me know the way to do this.
|
|
|
|
|
TreeView treeView = new TreeView();
treeView.Nodes.Add("Monday");
treeView.Nodes.Add("Tuesday");
treeView.SelectedNode = treeView.Nodes[1];
Something like that anyway This would select the "Tuesday" node.

No this does not work. Thanks anyways.
The scenario is something like this.
1. On one page I have a tree view.
2. I select a node and add the node vale in a session variable.
3. On another page I have the treeview.
4. Here I fetch the session variable i.e. the selected node value.
Now I have to use this variable to automatically select the same node.

i read somewhere that we have three ways of showing forms/dialogs (i did not remember exact text)
1- normal form.Show()
2- modal form.ShowDialog()
3-system modal ?
i don't know how to have system modal but it said that it will work for your purpose

No, it's not.
The user has, and always should have final control of their PC. There is no way to intercept the Ctrl+alt+del button press. Only the WinLogon process can receive notification of this key combo.
What is your reason for wanting to do this?

Don't have browsers on the computers.
Don't attach the computers to the Internet.
Detect the attempt and fail the student.
Mightn't they still be able to use a Web-enabled phone?

The propose is to prevent shop attendant not to use any thing except only my program which is developed for product ordering.

If that's the case, try to find information on how an information kiosk works (tourist info, trains, buses, those types). Most run Windows XP, but there is only one usable application.

They generally don't have QWERTY keyboards attached to them. You can probably intercept most key combinations using the UserActivityHook class here:
http://www.codeproject.com/KB/cs/globalhook.aspx[^]
The user will always be able to Ctrl -> Alt -> Delete and Ctrl -> Shift -> Esc it though. Why not just remove those buttons from their keyboard? Save a lot of hassle

ps: my some other windows like it wouldn't show suck error. And this is a child window of one MDI window.I don't known why?

dealon,
Yes, i understand what you're trying to do. But, what happens in code when you load the form?, is it connecting to a database?, doing some graphics?, Do you create any large collections? what...
You shouldn't get this error for just loading up a simple form, unless you have a billion forms open.
Regards,
Gareth.

Gareth, I think i need to get a new project to reproduce such problem because my original project has as many as 40 windows.Some work ok while others not.I don't known which code cause such errors and I will find out the codes exactly.
Later, I will show you more information for the errors.
Gareth,Thank you very much.
Regards,
Dealon.

Hi Everybody!!!
I m a intermediate in C#. I m designing an application for scanning images from any scanner using 'twain_32.dll' of the twain working group.
i found a code here on the code project which did most of the work on scanning the image and bringing it back to the application's picturebox.
But theres a problem in this code and that is this code does scan the images but during scanning it opens the interface of the attached scanner (ex. i have hp psc 1315 scanner) and the image is scanned via that interface and then the control hope to my application and the picture is copied to my application.
I want to create my own interface of scanning , i dont want my scanner's interface to open during scanning.
Hope u got my point.
Please suggest me how i can accomplish this.
