SUMMARY
This article shows by example how to get the IPROP_STD_LEFT, IPROP_STD_TOP, IPROP_STD_WIDTH, and IPROP_STD_HEIGHT values using the VBGetControlProperty function.
MORE INFORMATION
The IPROP_STD_LEFT, IPROP_STD_TOP, IPROP_STD_WIDTH, and IPROP_STD_HEIGHT properties are stored as floats. The following code shows how to call VBGetControlProperty to get these properties from a VBX and DLL. It is assumed that the standard property indexes found in VBAPI.H were used to build the control.
/* VBGetControlProperty is prototyped in vbapi.h */
#include <vbapi.h>
*** You also need to add "vbapi.lib" to the libraries in the makefile. ***
float fValue ;
int nRet ;
/* hctl would normally be passed in as a HCTL to the function using
VBGetControlProperty */
/* The third parameter must be the address of a float */
nRet = VBGetControlProperty(hctl, IPROP_STD_TOP, &fValue) ;
Now fValue has the value of Top property for the hctl control.
