User Reviews

  • Perfect abstraction of the nasty details and horrors of native Win32-API-Programming at the C level. Perfectly fitting into the tcl world of things! A great help in administering windows systems!

  • I am thrilled about this piece of software. An easy to use, powerful tool with a great documentation. Its help is inestimable. So I assign all 5 stars to this project.

  • twapi is easy to use and documentation is good. Are there plans to add support for the ReadConsoleInput function? I didn't see that one listed and I'd like to be able to read enhanced keys like the up, down, left, and right arrow keys, page up, page down, etc.

  • Forum didnt work... Can someone show an example formatting for a raw call to twapi::DecryptMessage and EncryptMessage? Thanks

  • A wonderful array of capabilities is provided by this package. I have barely scratched the surface with the COM interface and accessing network shares. Support is also great. Ashok is clearly passionate and interested in maintaining an excellent product!
