Namespace:  Microsoft.VisualStudio.Shell.Interop
Assembly:  Microsoft.VisualStudio.Shell.Interop (in Microsoft.VisualStudio.Shell.Interop.dll)

int QueryDebugLaunch(
	uint grfLaunch,
	out int pfCanLaunch


Type: System.UInt32
[in] Flags that determine the conditions under which to launch the debugger. For valid grfLaunch values, see __VSDBGLAUNCHFLAGS.
Type: System.Int32
[out] Pointer to a flag that is set to true if the debugger can be launched and false otherwise.

Return Value

Type: System.Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.

COM Signature

From vsshell.idl:

HRESULT IVsDebuggableProjectCfg::QueryDebugLaunch(
   [in] VSDBGLAUNCHFLAGS grfLaunch,
   [out] BOOL *pfCanLaunch

This method determines whether or not the debugger can be launched and the Launch menu item enabled. When QueryDebugLaunch sets pfCanLaunch to true and the user selects the Launch menu item, the project calls DebugLaunch with the same set of flags that were used to call QueryDebugLaunch.
