Re: Grabbing Text from a Field

[Steve Sabram]

I use this piece in my code.  It takes care of all the memory management
and resource finding.  I find I'm running a collection of common functions
I'm moving from project to project.
void EditFieldRead(FormPtr frmP, int ctrl_id, char *pInputBuffer)
{
    FieldPtr FieldCtlP = (FieldPtr) GetObjectPtr(frmP,
ctrl_id);
    VoidHand textHandle = (VoidHand) FldGetTextHandle(FieldCtlP);
    char *pText = (char *) MemHandleLock(textHandle);
    int len = StrLen(pText);
 
    if(len > 0)
    {
        MemMove(pInputBuffer,
pText, len + 1); // Grabs the terminating NULL
    }
    else
    {
        *pInputBuffer = NULL;
    }
    MemHandleUnlock(textHandle);
}
