I am working on Window application of Visual Studio 2.0. I want a check box column and a check box in the header of this column in a DataGridView. Later, on clicking this header check box all the corressponding check boxes should be selected or deselected as well and values of two other columns should also interchanged between them. This interchange of column values should also heppen if we checked the single check box.

Please help me out.
Thanks,

Code looks fine. Are adding any file extensions with the file name ? Try setting sfd.AddExtension = true;.

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia

Hmm, odd. Are you sure you havn't set the BackgroundImage property of the picturebox by mistake?

Hi,

I want to create one MSI Package with following requirement

1)There should not be any entry in Add Remove entry, Control Panel

2)The MSI package should use ASMFlag.sys file in C root to determine if the agent is installed or not. If file exists, do not install. If file does not exist, install.

3) When MSI package is created, the EXE will reside in a subfolder named 'temp'.

This is very urgent requirement. Please suggest how to create MSI Package.

To do what? Close the web browser, or end the users session? If it's the web browser, use window.close()* in the client javascript. If the session, the code behind should use Session.Abandon();.

*If the window hasn't been opened from another browser, it won't close without prompting the user.

Hi,

I have created two projects, One is an EXE and other one is DLL. The DLL is referanced by EXE Project. The Exe & Dll Are working fine.

I Need to hide code of dll. So I use .NET Obfuscator Community edition (Which comes with VS 2005) to Obfuscat dll. It was done successfully.

The problem is Now when I am executing Exe it generate errors about missing Classes (Those classes are Withing DLL)

What can I do for this scenario ? Is it the nature of Community Edition ?

Please help me to solve this problem.

Thanks

Dinesh

Are you using reflection to load those classes? I don't think the community edition is any good for this type of situation.

Take a look at the ObfuscationAttribute in the System.Reflection namespace.

Putting Letters Into a c# 2.0 winforms app

Hi all,

I was wondering if anyone could give me a push in the right direction Smile | :)

I am writing an application that needs to show letters. These Letters need to be updated with information about our customers from our database.
I have considered using RTF and regular expressions to find the positions to place the new data. I found a control TxTextControl but am worried that this may get a bit messy! Both in the database (storing huge RTF) and in the app.

Does anyone have any ideas on the direction I should take ??

Thanks
John

Well, as what you've described sounds exactly like mail merge, have you considered using Word? If you've got Word 2007 installed, you could even fill the information in by directly targeting the Word XML.

Not without using a word viewer. As a quick thought though, have you considered using WPF and its support for documents? It has an inbuilt document viewer that allows you to view XPS documents. Office 2007 does allow you to save documents as XPS, so you could possibly use automation in office to generate the documents and then open them up in the DocumentViewer control.

Thanks for the replies,

I need it embedded in the app so that I can put it out into the business and they can build up the letter by making selections e.g. a button that when clicked adds a disclaimer to the letter... these button clicks would then need to search a template document for a place holder and put in the relevant text. the docx seems to be able to do this but i need it so that the user can only manipulate the document in the app.

Any ideas Smile | :)

Well - the XPS solution would seem to be a goer for you. It's not trivial, but it will result in a document that you can manipulate through your code, and which renders out like a PDF. This[^] link should help.

Use the forms Resize event and the FormWindowState enum to determine the
forms current state.

private void frmMain_Resize(object sender, EventArgs e)
{
    if (System.Windows.Forms.FormWindowState.Minimized == FormWindowState.Minimized)
        this.Hide();
}

You have to handle resize event for the form. Assume your form is Form1

Form1 frm = (Form1)sender;
if ( frm.WindowState == FormWindowState.Minimized)
{
	//do your stuff here
}

Hope it helps
