Drawing Rectangles onto the screen What am I doing wrong?

[dvanderwel]

Hi,

I want to be able to draw a rectangle to the screen (1 pixel border) based on 
how large one of my text fields is.  This is my idea:

Use FrmObjectBounds to store the bounds of the text field, then use 
WinDrawRectangle to produce the rectangle.  Now I don't know whether this will 
work or not since im new at C programming.

So far my function looks like this:

void FlowTemplate1DrawBox(UInt32 textboxID){

        FormPtr frmP;
        RectangleType *rectP;
        
        frmP = FrmGetActiveForm();
        rectP = MemPtrNew(100);

        FrmGetObjectBounds( frmP, textboxID, rectP);
        WinDrawRectangle(rectP,0);
}

I get a memory error immediately saying I am trying to access an unallocated 
chunk of memory.  What am I doing wrong?

Thank you I appreciate any help!
