Overview

ScanTool is a desktop application that scans and analyzes files and directory trees and generates useful reports from the analysis of the files. For example, one report shows the structure and size of VB projects in the directory tree. Another report shows information about COM components referenced by the VB code. The program has an object-oriented design, with a different class handling each type of report.

The ScanTool sample consists of two VB6 projects:

  • ScanToolLib.vbp builds into a library, ScanToolLib.dll
  • ScanToolUI.vbp builds into an executable application, ScanToolUI.exe, which references the ScanToolLib.dll library

The source codes for these projects are located in the [INSTALLDIR]\samples\source\ScanTool subdirectory of gmStudio.

Two sample Migration Projects are included in the ScanTool example, depending on target language (C# or VB.NET) as shown below:

Project[.gmproj]Description
DemoScanTool_cshScanToolUI and ScanToolLib migrated to C#.NET, all COM externals migrated to .NET
DemoScanTool_vbnScanToolUI and ScanToolLib migrated to VB.NET, all COM externals migrated to .NET

The ScanTool source is comprised of about 2200 lines of code (LOC). 

   ScanToolLib.vbp
   clsCOMReporter.cls
   clsDirList.cls
   clsScanControl.cls
   clsVBPBinReporter.cls
   clsVBPCntReporter.cls
   clsVBPModReporter.cls
   clsVBPRefReporter.cls
   clsVBPSrcReporter.cls
   ScanToolLib.bas

The UI source is 

   ScanToolUI.vbp
   ScanTool.frm
   ScanToolHelp.htm
   ScanToolUI.bas

The DLL communicates its status to the EXE through COM Events. ScanTool also uses several external COM libraries and ActiveX controls: MSXML, Scripting, Common Dialog, and TypeLibInfo, and it also calls Win32 APIs, like ShellExecuteForExplore.

 


COM Dependencies

ScanTool depends on the following external COM components that must be installed on your workstation to perform the migration successfully:

ComDlg32.OCXMicrosoft Common Dialog Control
msxml6.dllMicrosoft XML, v6.0
scrrun.dllMicrosoft Scripting Runtime
TLBINF32.DLLTypeLib Information

Deployment

The ScanTool migrations all work on the ScanTool source and save outputs in the DemoScanTool workspace. The demos are available in both VB.NET (vbn) and C# (csh)

 

All the ScanTool migration projects have the following deployment settings:

      ProjectFolder = [INSTALLDIR]\samples\workspace\DemoScanTool
      DeployFolder  = %ProjFolder%\deploy

 

Log files showing all migration steps are created in the workspace\log folders.

      [INSTALLDIR]\samples\workspace\DemoScanTool\log

 

The .NET project files are deployed to the following folders:

      [INSTALLDIR]\samples\workspace\DemoScanTool\deploy\[project]_mgd_[lang].

where:

      [project] is the name of the migration unit associated with each
                migration task in the migration project.

      [lang]    is "csh" or "vbn" depending on the task settings.
