VBnet CoolTabs Utility
Use this utility to format the tab stops in a list or textbox.

*Although CoolTabs can generate the code required for older editions of VB, all API declarations and API constants must be replaced with the proper 16-bit Windows API equivalents. Also, if converting backwards note that some of the LB_ and EM_ message values changed between 16- and 32-bit Windows.
