Error in my post: It should be: "If the program is run in release mode, it prints out "NextDouble: Not infinity"!!". I modified this.
Luc Pattyn wrote: And did you ever care to print out range (that is, if it ever goes wrong) ?
Yes I did. The last line in NextDouble prints out range (if uncommented of course). It always gives that range is positive infinity and as I said in this case the program works as expected.

I set the TopMost property to true in the Load event, and I call BringToFront() in the Activate event.
But these things seem to have no effect. The form appears, but doesn't come to the front or stay in front.
The form Border Style is set to None, so it has no title bar or border.
Does that make a difference?
How do I cause a form to come in front of all other windows, and stay on top?

Try to set the ReadOnly property to true and Enabled to false and check its behaviour.

You can change the backcolor explicitly, so that your textbox will be in the color you choose...

we can create a a folder by using the statement
Directory.SetCurrentDirectory("C:\\");
Directory.CreateDirectory("Foldername");
Direcotry is a class which is under the System.IO namespace.
|
|
|
|
|
It's just
System.IO.Directory.CreateDirectory(@"c:\my directory");
no need to set the current directory ( which is a bad thing to do anyhow, as it can stop the other code from working )

Please - test to see if the directory exists before you attempt to create it:
if (!Directory.Exists(@"c:\foobar"))
Directory.CreateDirectory(@"c:\foobar"); Under certain circumstances, you might still get directory name collisions, but with this method you've at least got a fighting chance.

on completion of any change you could try something like the following:
DataSet = changedData = MailDataset.GetChanges();
if(changedData != null)
{
SqlDataAdapter.Update(changedData);
}
else
{
MessageBox.Show(" Error ...", "Error");
}

Apologies type in first line of code, correction.
DataSet changedData = MailDataset.GetChanges();

download one of the file in my local folder, it downloaded perfectly. And once again I download the same file in the same folder, an error occurs.
I want to check the folder before i download the file. If the file is alredy in the folder , then it won't download in the folder.
Can you give the code for above Scenerio?

File.Exists, perhaps ? I would have thought the save file dialog would tell you if the file exists
