Free stuff for registered Visual Basic owners

The Coolbar ActiveX control allows you to create a toolbar similar to the Internet Explorer toolbar. COOLBSMP.EXE is a self-extracting file installs a Visual Basic project that uses the Coolbar ActiveX control. The sample project contains a user interface similar to Internet Explorer.

In this Issue

This issue introduces a routine to determine if you are currently running in the IDE or a compiled EXE. This can be useful for development where you want to have different startups based on the how you are running the program (in the IDE or compiled). It can also be used when you develop a custom control and want to release it on trial basis to be used only in the IDE. You could use this routine to have prompt in the EXE that says this control is not licensed to be used in a compiled EXE until you register (or something similiar).


Public Function RunningInIDE() As Boolean



True if the application is running in the VB Development Environment (IDE) or False if running as a compiled EXE.

Sample Usage

This example shows how to use the subroutine.

    If RunningInIDE Then
        MsgBox "IDE - Design Time"
        MsgBox "Compiled EXE"
    End If
