Microsoft supplies debugging tools under the name of Sysinternals at the following URL:




You can download a tool named dbgview.exe from this location. You can use this tool to catch trace information from a .Net application used in a USoft application.


The following example illustrates how you could make use of dbgview.exe.

1. Download and install dbgview.exe.
2. Create a file with the extension .cs, e.g. myTrace.cs.
3. Type the following code into the myTrace.cs file:


#define TRACE

using System;

using System.Diagnostics;


class TRACE


public static void write( String message )


Trace.AutoFlush = true;


Trace.WriteLine( message);






4. In USoft Definer, create a new DotNet Component named TRACE
5. Provide the full path and filename of the file created in step 2 as the Program Source, e.g.
C:\Program Files\myCode\myTrace.cs


6. Specify the Assembly reference: System.dll
7. Save and check.
8. Start dbgview.exe from Sysinternals.
9. Start the USoft application.
10. Execute the following command in the SQL Command Dialog Box:


SELECT TRACE.WRITE( ‘Testing C# trace’ );


The listing in dbgview.exe will show the message.
