Thanks for the link.

I have been there prior to posting here and have tested their sample, but this does not handle word wrap properly.

Any other suggestions?

Dim f as System.IO.StreamWriter = New System.IO.StreamWriter("C:\file.txt")<br />
f.Write(TextBox.Text)<br />
f.Close()<br />
Shell("Notepad.exe /p C:\file.txt", AppWinStyle.NormalFocus)<br />
System.IO.File.Delete("C:\file.txt")<br />

Not the most elegant way, but it works for me.

I was actually thinking of doing something like this, Thanks. Smile | :)

But is there some command-line arugment to allow the print dialog to show up? I know that the user may not use their default printer, so a print dialog would be really useful.

Any ideas?

Im now using mscomm in a VB6 project but as I understand this component does not support ports abow com16. If USB BT, IR and serial dongles is used ports easily starts getting numbers abow 16.

What is the fix or solution to this problem?

If there is no solutions for mscomm suggestions to other components with a word about own experience would be great, comersial or free.

In VB6, there isn't a fix. You'll have to find a COM-based SerialPort control that supports this. I don't know of any.

How to access a Rich Text Box from multiple threads

immes4-Jul-05 5:32

4-Jul-05 5:32

Hi all,

my problem is : I have a programm with multiple threads running. These threads should write a status message in a global
rich Text Box located in the main Form.
This textbox is shared and can be accessed by a property wich returns the rich text box. Also the box contains a synclock.

Now from time to time I get a NullReferenceException at System.Windows..Forms.RichTextBox.EditStreamProc
System.Windows..Forms.RichTextBox.UnsafeNativeMethodsCallWindowProc

etc.

I don't get the line where the exception occured.

It would be great if you could help me

Best Regards

immes

This is a problem in that the EditStreamProc does not do a check to see if
the editStream member of the RichTextBox class is set to null or not before
trying to write to it. This is what causes the NullReferenceException. If a
check for null is added at the top of the method, the error goes away.

Are you sure you are accessing properties/methods of the Textbox using BeginInvoke/Invoke? This[^] article might help you get it right.
