VbTdrv is the Visual Basic version of the Tdrv test program. See Testing with Tdrv for details on VbTdrv's features and operation.
VbTdrv is distributed as a complete Visual Basic project consisting of the following files:
| VbTdrv Project Files | |
|---|---|
| VbTdrv.vbp VbTdrv.vbw |
Visual Basic project files. |
| VbMain.bas | VbTdrv entry point. |
| VbTdrv.frm VbTdrv.frx |
Main VbTdrv form. |
| VbAbout.frm VbAbout.frx |
About box form. |
| VbTdat.frm VbTdat.frx |
Test data form. |
| VbText.frm VbText.frx |
Text box form. |
| Hex.bas | Hex format and byte conversion routines. |
| Statistics.bas | Statistics formatting routines. |
| Status.bas | Status Report formatting routines. |
| Tdat.bas | Test data frame handling routines. |
| Using.bas | Using VbTdrv text access routine. |
| Vtx.bas | Verified transmission (Vtx) frame handling routines. |
The VbTdrv project also uses Laygo32.bas and X21bis.bas.
Just double-click VbTdrv.vbp to load the project into Visual Basic.
VbMain.bas contains Sub Main() where program execution
begins.
By default, the VbTdrv project contains the command-line arguments:
stack6.cfg x21loop.cfg
This instructs VbTdrv to use the LayGO hardware emulation driver in loopback mode. You can change which configuration files are loaded by editing the Command Line Arguments field on the Make property sheet in Visual Basic's Project → VbTdrv Properties... dialog.
