Hi all,
A tyical Application of mine, takes data from the
serial port, and has to display the data in the form
text field on Palm.
I tried to code it, but this is giving me an error,
and I have to reset the Palm everytime i run the
application.
Code :
case MainUnnamed1001Button:
{
serialPrintch(&one_byte,1);
error=SysTaskDelay (delay);
qtyReceive = serialGetch(buffer, sizeof(buffer),1);
error=SysTaskDelay(delay);
// if (qtyReceive!=0)
// FrmAlert(CantopenserialPortAlert);
if (qtyReceive)
{
serialPrintch(buffer,qtyReceive);
}
FrmGotoForm(SecondFormForm);
//ClearField(SecondFormSecondFormReferenceFeildField);
handled = true;
}
Till this point, the application runs fine and I am
able to get the buffer displayed on my Hyperterminal.
Now, I need to put it in the text field of my second
form. the function that I am using is something of
this sort:
Void SecondFormTry(Char *buffer)
{
FieldType *field;
MemHandle memH;
Char *text;
Int16 textLength=0;
Int16 bufferLength;
Err error;
field =
GetObjectPtr(SecondFormSecondFormReferenceFeildField);
memH = FldGetTextHandle(field);
if (textH) {
FldSetTextHandle(field, NULL);
text = MemHandleLock(textH);
bufferLength = StrLen(buffer);
if(buffer)
{
text="";
while(textLength<bufferLength)
{
*text=*buffer;
buffer++;
text++;
textLength++;
}
}
}
MemHandleUnlock(memH);
FldSetTextHandle(field, memH);
FldDrawField(field);
}
the program compiles fine, and works fine till the
first stage, in which I can send data through the
data, and echo the string to see it on my
hyperterminal. Then this application gets hung, and I
have to reset the Palm.
Any help, or Suggestions, in this regard shall be
greatly appreciated.
thanks
murali.
