I have my X-Function that can be called by two differen ways:
1. By user in command window with showing dialog "MyXFun -d"
2. From my C-code by XFBase::Evaluate()
I want in "MyXFun" to recognize which the way the function is executed: by pressing OK button in dialog or by xf.Evaluate()?

Hi,

When you use "MyXFun -d", the dialog will be opened. But the dialog will not open for XFBase::Evaluate(). In the _before_execute event of the X-Function, the argument int dwCntrl can be used to check whether the dialog is open. However, when using XFBase::Evaluate(), the _before_execute event function is not called. So, you can use the XFBase::Run() method instead. Then in the _before_execute event function, check whether the dialog is opened or not like:

if( LTXF_SHOW_DIALOG & dwCntrl )
	out_str("dialog show");
else
	out_str("dialog not show");

See the document here.
