The IsCompiled property returns a Boolean value indicating whether the Visual Basic project is in a compiled state.
Setting
The IsCompiled property is available only by using Visual Basic and is read-only.
The IsCompiled property returns True (–1) if the project is in a compiled state.
Remarks
You can force Visual Basic to compile the project from the user interface while in module Design view by clicking Compile All Modules or Compile And Save All Modules on the Debug menu.
The IsCompiled property of the Application object is False (0) when the project has never been fully compiled, if a module has been added, edited, or deleted after compilation, or if a module hasn't been saved in a compiled state.
