Question and Answer Database FAQ254C.txt Setting the size of font in a VBX control Category :Windows API Platform :All Product :BC++ 5.x Question: In my Windows API (not OWL) program, why does my call to VBXSetPropByName(hVBXCtl, "FontSize", MyLong); not work? Answer: The prototype for VBXSetPropByName() (and VBXSetProp()) specifies LONG as the type of that third parameter. The FontSize property expects a float. Even if you pass a float, the compiler will convert that float to a long and this long will be interpreted as a float which will yield unexpected results in the size of the font. Try this: float fontSize = 20 * 20; VBXSetPropByName(hTheVBXControl, "FontSize", *((long*)&fontSize)); This will fool the compiler into thinking the contents of fontSize is a long, not a float. This way the compiler will not convert fontSize, it will be passed as is. 7/2/98 10:32:32 AM
