No I can't because it is specific to the device you are trying to access. So, please answer my question: which device are you trying to communicate with ?
Normally, you should have some documentation supplied with the device.

 Why do you want to do that ? What do you want to do with those devices if you don't know how to communicate with them ?
mirtu wrote: but first i want to access PenDrive
You can simply access the files the standard way. The driver takes care of everything. The only thing a bit more tricky would be to know which driver letter is used by the device, but I don't know exactly how to do that. I guess you should check somewhere in the registry.

I created a class derived from CStatic control. I used this class to create a control similar to a clock control in which a needle rotated continously to show some value. I used onPaint to draw the control's face and a timer to change the position of the needle. In the onTimer function, I used the CDC object to change the position of the line and I am calling the Invalidate function.
I used this control by adding a static control in a dialog in a application. and then created a member variable for the static control and changed member to be an object of my class.
Now when I run the application, my control works fine. But a small blink seems to appear when the needle changes position.
If anybody has suggestions to avoid the blink, Please tell me.
Thanks in Advance,
Mohan

If you are already changing the line position on DC why call invalidate again. Or else dont change just call Invalidate in Timer.

This is because it is getting painted twice for every WM_PAINT it receives. The problem is the WM_ERASEBKGND message, which is sent every time we call BeginPaint. This isn't a problem really - Windows is doing us a favour, because the default action for WM_ERASEBKGND is to draw a nice window background for us (using the window's default background brush), which we can then paint on top of in the WM_PAINT handler.
However, our WM_PAINT handler also draws the control's background, so there is no point in this happening twice. Therefore, we need to prevent the default WM_ERASEBKGND behaviour from happending. As usual, there are a number of ways to do this.
Set the window's background brush to NULL. (Set the hbrBackground member of the WNDCLASS structure to zero when you register the window class).
Return non-zero in the WM_ERASEBKGND message handler.

You can use double buffering. Draw the clock on an in-memory bitmap, and in your OnPaint () handler just BitBlt the bitmap to the OnPaint CDC.

Is it possible to layout the text content of a RichEditCtrl in form of two columns ?
Thank you in advance.

Are you opposed to using a list control for this?

may be. Becuase I am just using the RichEditCtrl for its printing possibilities : I am doing a chess program. I show moves notation using certain control, but when I have to do the printing, I just call a certain hidden RichEditCtrl to receive my moves tString, then it is of its responsibility to lay them optimally, ie know when to return to the line, when to add another page when space isn't enough..etc.
Just to avoid using complex or lengthy things my own.
The problem is that the standard way chess printing is when moves notation is laid out in two columns, like a newspaper. For that reason I asked about how to do it in RichEdit control.
last day I checked paraformat and I think with it I can restrain certian text to the left side, but what about the right side, how can i tell the rich edit to display the remaining paragrphs to the right of the page ?
Anyway, thank you for your willingness to help me.

Fair enough. When adding to the richedit control, use a tab or spaces as the column separator. You might also consider changing its font to something fixed-spaced.

Suppose I have the following moves notation text :
1.Nf3 Nf6 2.c4 g6 3.Nc3 Bg7 4.d4 O-O 5.Bf4 d5 6.Qb3 dxc4 7.Qxc4 c6 8.e4 1 -0
It must not be displayed as :
1.Nf3 Nf6 2.c4 g6 3.Nc3 Bg7 4.d4 O-O
4.d4 O-O 5.Bf4 d5 6.Qb3 dxc4 7.Qxc4 c6
8.e4 1 -0
No, but rather this way, which is very difficult to do by embeddins tab caracters onto the moves String :
1.Nf3 Nf6 2.c4 g6 6.Qb3 dxc4 7.Qxc4 c6
3.Nc3 Bg7 4.d4 O-O 8.e4 1 -0
4.d4 O-O 5.Bf4 d5
Big problem.Would you receive screenshots of my prog. ?

This actually looks like four columns mixed with two, and move #4 has been repeated. How about:
1.Nf3 Nf6 2.c4 g6
3.Nc3 Bg7 4.d4 O-O
5.Bf4 d5 6.Qb3 dxc4
7.Qxc4 c6 8.e4 1 -0

simply disable it...
EnableWindow(/*param set to false*/)
Somethings seem HARD to do, until we know how to do them.

What exactly you want to achieve can you explain.
You can set 'Readonly' property of text box if you don't want user to change the contents.
Use combobox style "Droplist".
Does this help.

Sandip.
