Hello,

i'm a starter with CVI and i have a problem with struct.
I need the function GetActiveTableCell(.... for read the actually positíon from my curser.
I need fpr this function the struct

typedef struct
   {
   int x;
   int y;
   } Point;
But in my projekt did't it proberlly.
I think a have a generally problem with struct.
I insert the code "typedef struc..." in the head from my projekt (were the variablen is defined) and in the underfunction i use the type.
But i become four error-massage.

-  126, 15   Redeclaration of 'Point'.
-  752, 26   Undefined size for 'incomplete struct Point defined at APA.c:752 Position'.
-  761, 70   Illegal use of type name 'Point'.
-  761, 75   Type error in argument 3 to `GetActiveTableCell'; found 'pointer to Point' expected 'pointer to Point'.

Can me help somethere.

Thanks

Hello Wolf4142,

the typedef Point is already defined in CVI (userint.h). That is why you get the errormessages. Just leave out the typedef and your code will compile just fine.

Just a note: a "Rectangles and Points" library is available in the User Interface Library. You might find some usefull functions in there...
