Example
/*========================================================= Create the struct struct { int var1; unsigned char var2; unsigned int var3; char var4[128]; } =========================================================*/ $str = "int var1;ubyte var2;uint var3;char var4[128]"; $a = DllStructCreate($str); if ( !$a ) { MsgBox("Error in DllStructCreate"); exit(); } /*========================================================= Set data in the struct struct.var1 = -1; struct.var2 = 255; struct.var3 = 777; strcpy(struct.var4,"Hello"); struct.var4[0] = 'h'; =========================================================*/ DllStructSetData($a,"var1",-1); DllStructSetData($a,"var2",255); DllStructSetData($a,"var3",777); DllStructSetData($a,"var4","Hello"); DllStructSetData($a,"var4","G",0); /*========================================================= Display info in the struct ;=========================================================*/ MsgBox("Struct Size: " .
