Hi. Iam developing some app and for security reasons I want to disable running that app on certain computers.
I can do that by checking the hdd id. Is there any better way, because hdd is much more replaceable than CPU?
Sample:
Some user logs first time on to that app over the net. Program saves the hdd id into the database.
Next time user logs, app checks hdd id previously saved in database and if it's equal, then the user can be logged.

If you want to output to excel then the easiest will be in the CSV format (this will not apply any formatting). And RTF for Word likewise.
If you do want the special features of Excel and Word then Aspose have some components for creating and opening Word and Excel files.
Alternatively if you want a freebie then I'm sure (I seem to remember coming across them) there are articles on CP about how to do this.
Another alternative is to look into the Word and Excel XML formats (Office XP onwards), this may be the simplest option unless you can find an article on how to do it another way on CP.

Hi,
We are creating a C# Windows application using VS 2005.
It reads in an xml file and creates tab pages that each
have a datagrid that holds the specific information
for that tab's node.
We have been able to programmatically give the tab.text
(the label on the tabs), but when we try to add the
specific data for each tab into a datagrid on the
tab's page, all of the data gets added instead of the
data for just that node.
Perhaps we need to clear the grid first???
Any help would be appreciated.
Thank you in advance,
Anne

I have several labels stored in an array of label controls (Label[] drgLabel). The labels are placed in a panel control. I want to be able to move the labels around the panel using drag and drop technics. I do not know how to get the mouse_over event associated with the label because the labels do not have specific names. Do I have to write the mouse_over event for the array of labels (drgLabel)? Any suggestions will be greatly appreciated.

You can bind the events in a loop:
foreach (Label label in drgLabel) {
label.MouseOver += new MouseEventHandler(drgLabel_MouseOver);
}
Which Label actually received the vent can be obtained from the sender. You surely have to cast this one:
private void drgLabel_MouseOver(object sender, MouseEventArgs mea) {
Label label = (Label)sender;
}
All events needed for drag and drop can be bound this way.

I have a program that was running really well on my computer. For sometime now, it has been running really slow and I find it hard to understand. I have scanned for viruses and spyware but couldn't find any and no possible reasons as the why the program is running that slow. Any suggestions? My computer specification is : pentium4, 3.40GH, 512MB

1) Is this the correct forum, is it a C# program?
2) Has your disk been defragged recently?
3) Do you have lots of services / background apps running?

It is a C# project i am working. I do not have lots of back apps running. This is because I am running below the physical memory. Yes it has been fragmented . Thank you.

Well, there could be thousands of reasons...
What kind of program is it? What does it do? Who made it? How slow is "really slow" really?

I am new to C#, and I have compiled a simple exe (a WindowsFormsApp, not a console app) to perform an operation, and want to notify the calling application when it has completed and return a status code.
ApplicationExit();
Just seems to exit, and even if I try to set a return code with:
System.Environment.ExitCode = #;
I don't seem to get anything either.
Can anyone help??
Thanks,
Mark

Hello,
Try the following
[STAThread]
static void Main()
{
Application.Run(new Login());
return 999;
}
In the retun, you get the exit code

Doesn't have to be, valid types are void and int according to the C# spec I seem to remember, same as in ANSI C

Main() can be either void or int:
[STAThread]
static int Main(string[] args)
{
if (error)
return 1;
else
return 0;

Ravi,
Yes, your code works perfectly. Thanks!
This code works also:
Application.Exit();
Environment.Exit(2445);
Thanks,
