Hi,
Maybe you have realized the prototype of this method:
int ExecuteLabTalk(LPCSTR lpcszArgs, vector<string>* pvsVarValues,
LPVOID lpRetData = NULL, int nRetDataXVT = XVT_INT, int* lpOCerr = NULL,
DWORD dwCntrl = 0, int nRecalculate = AU_NONE);
Argument DWORD dwCntrl can be set to LTXF_SHOW_DIALOG for opening the dialog. For example:
xf.ExecuteLabTalk(NULL, NULL, NULL, XVT_INT, NULL, LTXF_SHOW_DIALOG);
