Luciano,
I get a different memory location but the same effect if I try to cast
'display" as a char * in the line from CtlGetValue.
The function code is as follows:
Boolean MainFormDoCommand(UInt16 command)
{
Boolean handled = false;
//get the Main form pointer
FormType * frmP = FrmGetActiveForm();
//set up slider
ControlType * sldPtr;
char * size = "12";
char * strDisplay = "this is a test";
int display;
//set up field
FieldType *field;
UInt16 fieldIndex;
switch (command)
{
case OptionsAboutMedStim:
{
FormType * frmP;
/* Clear the menu status from the display */
MenuEraseStatus(0);
/* Display the About Box. */
frmP = FrmInitForm (AboutForm);
FrmDoDialog (frmP);
FrmDeleteForm (frmP);
handled = true;
break;
}
case MainInputSlider:
sldPtr = FrmGetObjectPtr(frmP,
FrmGetObjectIndex(frmP,MainInputSlider));
display = (long)CtlGetValue(sldPtr);//returns the
value of the slider
strDisplay = StrIToA (size,display);
fieldIndex = FrmGetObjectIndex(frmP,
MainOutputField);
field = (FieldType *)FrmGetObjectPtr(frmP,
fieldIndex);
FrmSetFocus(frmP, fieldIndex);
FldInsert(field,strDisplay,StrLen(strDisplay));
handled = true;
break;
case MainClearTextButton:
fieldIndex = FrmGetObjectIndex(frmP,
MainOutputField);
field = (FieldType *)FrmGetObjectPtr(frmP,
fieldIndex);
FldEraseField(field);
handled = true;
break;
}
return handled;
}

Subject: Re: help on integer to string conversion
I mean, what are size and display?
The function prototype is:
Char *StrIToA (
Char *s,
Int32 i
)
Is 'size' a char pointer and display the integer you want to
convert?
