defining DWORD in uir

[38090]

Hi,

   I have a ring slide in .uir with constant name RATE. It has been initialised to int. i m trying to pass its value in my source code using

GetCtrlVal (panelHandle, PANEL_RATE, &BAUD_RATE);

BAUD_RATE has been declared as DWORD in my source file.

On debugging it gives me an error

  Type error in argument 5 to `birdRS232WakeUp'; found 'pointer to DWORD' expected 'DWORD'.

I guess this is because RATE has been defined as int in the uir. I have tried a few combinations but it does not work. I need to keep BAUD_RATE as DWORD.What do i define RATE as?

Can u help me with this

Thanks in advance

DWORD is a type that is equivalente to an unsigned long (as defined into CVIDEF.H include file), so it has the same lenght as INT type. You can define your rinh value as unsigned int instead of int and you can represent a DWORD value in it and pass back its value to a DWORD variable. To go to the definition of a type you can right-click on the type itself and select "Go to tefinition" option (or press Ctrl+I which is equivalent), this provided your project has been succesfully compiled and linked, otherwise you will get a "no definition error".

The problem you are finding is not related to retrieving the ring value but to how you have defined a parameter in 'birdRS232WakeUp' function and how you are calling it: it seems that your function parameter is defined as DWORD and you are actually calling this function passing a pointer to a a DWORD variable instead of the variable itself.
