You could do something like this example
Dim fs As System.IO.FileStream
Dim scrFile As System.IO.StreamWriter
strFileName = "some path and filename"
If Not IO.File.Exists(strFileName) Then
fs = New System.IO.FileStream(strFileName, IO.FileMode.OpenOrCreate, IO.FileAccess.Write)
else
'Just open file here
Endif
code is posted "as is" an is just an example.
You could check out the IO namespace
http://msdn2.microsoft.com/en-us/library/system.io.aspx[^]
http://msdn2.microsoft.com/en-us/library/system.io.filestream.aspx[^]
this will properly give you a good idea which statements you need
It's my opinion that nothing is impossible, it's "just" at matter of enough knowledge, time and money.

What do you mean by "empty"? Do you mean it is an empty string? Or do you mean it is a null value?
What error message do you get?

i meant a null value , when you have a null value in a field in the database & you try to get this field to your application in a textbox it dosen't want to

Then check if it is null before attempting to populate the text box. A null from the database will be a System.DBNull.Value

hello,every one
i want ask about how i can convert the pixels of any image into 3RD pixel
thank alot;)

I think that you have to explain what you mean. What is a "3RD pixel"?
I tried searching the web for "3RD pixel", but obviously all I found was a lot of "3rd pixel", e.g. in the meaning of "third pixel".

The following will give you all files with the extension 'dll':
Dim di as System.IO.DirectoryInfo = new System.IO.DirectoryInfo(myPath)
Dim fi as FileInfo() = di.GetFiles("*.dll")
You can search by any pattern you like.
You can also use File.Exists to check whether a specific file exists.

I have make a form (bollon) just have the same function and appearence of new email arrive in Outlook 2003.

Are you using VB.Net?
If so, you can use Form.SendToBack() Method Just after
Form.Show()
Make sure TopMost property of the form is set to false and you dont use Form.ShowDialog()
|
|
|
|
|
Sorry, My situation is,
Show the box topmost, but doesn't take the focus from main form.
|
|
|
|
|
Good then, what you can do is
Dim frmChild As New ChildForm
fr.Show()
Me.Activate()
PS: You can't use ShowDialog
