I saw an effective approach a few years ago that divided the character into a grid, then computed the average (over the given samples) and standard deviation of each grid cell.

Different characters will have different distributions, and the standard deviation will give a measure of how reliable each value is.

In the example I saw, discriminant analysis was used to identify characters from the grid values.

That may pull a tough one on the OP. He may post a query asking how to port LPVOID to Linux. Laugh | :laugh:

Hi all,
In My application before starting Worker thread i m using CWaitCursor but its not displayed.

even i try it inside of Worker thread but its not working here also.

so please tell me how can i use CWaitCursor in Worker thread.

thanks in advance.

There's a flaw in your logic here. If you compute things in a worker thread, it means that your UI will still be responsive. So why do you want to display a wait cursor ?

Actually i done calculation in worker thread and display sum result on modelless dialog box that show on Main dialog box,so i want to display wait cursor here .

You can do a BeginWaitCursor / EndWaitCursor.

Let the worker thread work and the UI thread handle the UI: setting the cursor is part of the UI.

You can use WM_PASTE, if it's an edit control, directly and your intention is to paste some text from clipboard. Also you can try SendInput[^].

You should not be doing such a thing though, you've been asking it for something like a month here. So...

Send key-stroke messages in this order:

Control (Key down)
S (key down)
S (key up)
Control (Key up)

WRITE IT YOURSELF!

Use PostMessage[^] with WM_KEYDOWN[^], WM_KEYUP[^] to send normal key press event.

Similarly use WM_SYSKEYDOWN[^] and WM_SYSKEYUP[^] for sending a CTRL key press event.
