Hi everybody,
Just look to this simple code.
/*************A simple function for setting the ****************
**************maximum value in scroll bar ******************/
void SetMaxScrollBar(short setVal)
{
short val=0,minVal=0,maxVal=0,pageSize=0;
ScrollBarPtr sclPtr=(ScrollBarPtr)GetObjectPtr(Resource2SkillScrollBar);
SclGetScrollBar(sclPtr,&val,&minVal,&maxVal,&pageSize);
SclSetScrollBar(sclPtr,val,minVal,setVal,pageSize);
return;
}
I am calling this function like this-->
SetMaxScrollBar(20);
Now when I debug this program, in the function niether the values of val,
minVal, maxVal or pageSize sets to zero ( in initializing part) nor the
parameter setVal changes to the argument value(ie. 20).Furthermore in whole
function values don't change(no effect of SclGetScrollBar() function! They
stuck to -1).
I am totally confused with this behaviour of the program.
In fact I tried this also-->
/**************************************************/
void SetMaxScrollBar(short setVal)
{
short val=0,minVal=0,maxVal=0,pageSize=0;
//
setVal=200; // No any effect of this statement !
return;
}
Can anybody point out my/system's mistake in this case?
Bye
Rajesh
