IVsDebuggableProjectCfg2.OnBeforeDebugLaunch Method

Provides a method the implementer can use to perform necessary actions before the actual launch of the debugger.

Namespace: Microsoft.VisualStudio.Shell.Interop
Assembly: Microsoft.VisualStudio.Shell.Interop.8.0 (in microsoft.visualstudio.shell.interop.8.0.dll)

int OnBeforeDebugLaunch (
	[InAttribute] uint grfLaunch
int OnBeforeDebugLaunch (
	/** @attribute InAttribute() */ UInt32 grfLaunch
function OnBeforeDebugLaunch (
	grfLaunch : uint
) : int

Return Value

If the method succeeds, it returns S_OK. If it fails, it returns an error code.

At the beginning of debugging, the solution build manager first calls OnBeforeDebugLaunch on each project supporting this interface. It then goes through the projects again and performs the actual call to DebugLaunch.
