Re: Printing TextBox Text Anonymous6-Jul-05 4:35 Anonymous 6-Jul-05 4:35  I was actually thinking of doing something like this, Thanks. 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? how to do VB6 and serial ports abow COM16 aslm4-Jul-05 9:44 aslm 4-Jul-05 9:44  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. re Me Re: how to do VB6 and serial ports abow COM16 Dave Kreskowiak4-Jul-05 13:47 Dave Kreskowiak 4-Jul-05 13:47  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.

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 Re: How to access a Rich Text Box from multiple threads progload4-Jul-05 6:36 progload 4-Jul-05 6:36  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. http://www.error-bank.com/microsoft.public.dotnet.framework/75936_Thread.aspx[^] Re: How to access a Rich Text Box from multiple threads S.
