I have a DataGridView that triggers Parse, CellValidating and CellValueChanged events.
I need to change the active cell in response of one of these events. For example, if the value of the cell is "1" I need to go to the third columns of the grid, and things like that.
The problem is that apparently I can't change the active cell while I'm still in the event. If I do that, strange things happen, ranging from no effects to events calling themselves resulting in stack overflow.
I managed to solve it with a dirty trick, but I am not satisfied yet. What is the correct way changing the active cell within an event?

Have you tried to change the active cell from CellValidated event handler?

I am writing a Windows Service that I may have to install more than one instance of per computer. Is there a way to change the DisplayName property and default install location using user provided information in ServiceInstaller project during install time?

If the ServiceInstaller produces an MSI (Windows Installer) then it is very likely the MSI can be changed. Using Visual Studio to do that may not be possible, it may require using a different tool.
The most likely observation about your scenario is that you are wrong about needing to install the service module more than once on single computer. I highly recommend that you double check your analysis and conclusion regarding that issue.

Did you mean to tell the original poster that? I first used Orca about 5 years ago.  However given the OPs apparent lack of experience with MSI databases I did not consider working with the raw tables a viable choice for them. I certainly could be wrong about that. ![Beer | [beer]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/beer.gif)

Yes, I said about Orca because you specified about using a different tool. If the original poster will choose to change the installer, as you told him, he will know what tool to use.

I have the SaveFileDialog set up to save .txt files. When I try to save a file with a different extension .jpg. It goes ahead and saves it in .jpg format. AddExtension does not append the .txt extension to the file name.
Please help.

Hi,
It's actually doing what it is supposed to do. The extension is only added if one is not present.
e.g.
myfile -> myfile.txt
myfile.txt -> myfile.txt
myfile.jpg -> myfile.jpg

Shouldn't the extension added to the file depend on the currently selected file filter. The filter in this case is .txt.

Shouldn't you be checking what the documentation says about it?
as in "Gets or sets a value indicating whether a file dialog automatically adds an extension to a filename if the user omits an extension."

Hi,
Typically the PictureBox is used to display graphics from a bitmap, metafile, icon, JPEG, GIF, or PNG file. I think you need a graphing control. You may want to look into http://www.codeproject.com/KB/graphics/zedgraph.aspx[^] which I've seen recommended on this forum previously.
Alan.

Whenever an event occurs that may disrupt the graphics of the picturebox, be sure to call picturebox1.Invalidate(). This will for the picture to repaint itself. If you are doing custom paint routines it is usually recommended that you create a new custom user control.

Hello Thomas
Thanks for replyng
Actually problem is that, i want to store the image of picture box in a object so that when it gets repainted because of minimization of picture box or any other window comes above it. So that it will reduce the time to redraw it. And one more thing to tell that while drawing in the picture box, there are near about 400000 points. and because of that its taking so much time.
Regards

you could assign the contents of the picture box to a Bitmap Object...
manipulate the Bitmap object via setpixel and getpixel
and the assign it back to the Picturebox
Does this help?

Hi Guys 
I am working on a WinForm Project (VSS2008) with SQL Reporting Services (SQL Server 2005). I have multiple reports that need to be printed ad-hoc. So far, I have placed each report into a seperate windows form and render the report within this form. Once referenced, these forms can be called from anywhere in the project using the Form.ShowDialog() method. Once the form is rendered I call ReportViewer.PrintDialog() to pop up the print dialog. This all works fine.
The Developement Specs asks for the form to be printed automatically. That means then when the form is called, it must render and bypass the print dialog, and then print the report (.rdlc) automatically. I have been struggling with this for a while now.  I am still new to development and hope that someone can help me.
 Basically, is there an easy way to programmatically trigger a Report Print (like clicking print on the Print Dialog) once the report has been rendered?
Thanks is advance.

I am working on a gaming project. The code has been migrated from .Net 1.0 to .Net 2.0.
I am using Sdldotnet in this project. Sometimes when action was not complete, the game crashes and error message is shown "Send or Don't Send". The error is
"Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
Suggest me something that helps me out of this.
Thanks in advance.

Looks like an authorized access taking place. Bad news for you is, it can be due to anything and you would have to debug it. If you can reproduce the steps of the crash then your lucky(you have some lead) or else add try/catch in your main and see if the stack trace helps in providing some lead!!
