You can use the scroll messages for this.
OnVScroll or OnHScroll.

hello friends,,
I have established serial communication with RABBIT3000 (an 8 bit microcontroller).

The packet from the microcontroller is sent to the PC only on the PC demanding it. The demand is sent through one of the variables in the packet sent from PC.

When the PC receives packet from the microcontroller, it receives the correct packet for the first time. During my second request and further,
the Pc keeps receiving the same packet that it received first.
The packet from the microcontroller is updated on some conditions so that its different values in the packet memebers each time it is sent to teh PC on demand.
but when I try sending a different packet (microcontroller updates the packet structure members) to the PC, it still receives only the same packet that it received first and not the updated one.

I receive the packet using Readfile and store the values in a circular buffer.

On the microcontrollers end, the changed values is what is sent in the packet. I have debugged on the microcontroller end and it is fine.
Why is the PC receiving the same packet ?
What could be the possibility? any suggestions?

Thanks in advance.

hi white sky,

There is no problem in the code but i am able to see the CFormView Embeded inside the Dialog. Because in the Button Event i am creating the CFormView and Showing it.

My intention is to Show as another Window for the CFormView. Presently it is showing inside the Dialog window it self. It is not able to show as a separate Window for CFormView when i click the Button in the CDialog.

please help me out.

uday.

Use MoveWindow/SetWindowPos in some timer function or a thread

Somethings seem HARD to do, until we know how to do them.

in vs 6 how do you remove a .h or .cpp file if you added it by mistake?
i know you can exclude it from the build but how do you remove it all together?

5-Jul-06 16:35

Hi all,

In my design, i should display the individual character which are keyed in by the user into the combobox. lets say user need to key in the word "HELLO" in the combobox. if the user press "H", one message box should show the letter "H". the same way for all other letters. So,

How do i get the individual character which has been keyed in using the keyboard?

Thanks in Advance.

Regards,
Ram
