Overview
The GetLineCount function will return the total number of lines in a Mapped Text Object.
Syntax/Parameters
Syntax
int = GetLineCount ( handle hObject );
Parameters
hObject
A handle to a valid Mapped Text or Edit Object.
Return Value
Returns an int containing the total number of lines or -1 on failure. Use the GetLastError function to retrieve error information.
Remarks
The line count of a Mapped Text Object is dynamic depending on actions performed. Therefore, if lines are inserted or deleted or if a segment is written, this value will change. Since a Mapped Text Object can be associated with a window or other more complex objects, the line count may change outside of the actions of the script. Use the GetLineCount function to return the current value.
In a Mapped Text or Edit Object, there is always a “line”; therefore, an empty file/object will always contain 1 line.
If the hObject parameter is invalid, the GetLastError function will return ERROR_FILE | ERROR_INVALID_HANDLE.
