You can create an XML-based .vsct file from an existing command table .ctc source file. By doing this, you can take advantage of the new XML-based Visual Studio command table (VSCT) compiler format.
To create a .vsct file from a .ctc file
- Obtain a copy of the Perl language. 
- Obtain a copy of the Perl script ConvertCTCToVSCT.pl, typically located in the - <Visual Studio SDK installation path>\VisualStudioIntegration\Tools\bin folder. 
- Obtain a copy of the .ctc source file that you want to convert. 
- Place the files in the same directory. 
- In the Visual Studio Command Prompt window, navigate to the directory. 
- Type - perl.exe ConvertCTCtoVSCT.pl PkgCmd.ctc PkgCmd.vsct- where PkgCmd.ctc is the name of the .ctc file and PkgCmd.vsct is the name of the .vsct file that you want to create. - This creates a new .vsct XML command table source file. You can compile the file by using Vsct.exe, the VSCT compiler, as you would any other .vsct file. - 备注 - You can improve the readability of the .vsct file by reformatting the XML comments.
