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.

In my application in one phase i save some values of this combo box in database.

in second phase when i again open the dialog box for check saved values,
than in case of drop list the saved values are not shown,while in case of dropdown its done.

so i just dont want to use droplist option.

and i want to stop enter value in edit box of combo box because i already add string in combo box in OnInitialUpdate function of Dialog.

I dont want to enter any other values.

so please tell me what can i do.

I don't understand this. It has nothing to do with combo style.

Whether you use the CBS_DROPDOWN or CBS_DROPDOWNLIST style, that has nothing to do with how you add items to the combobox, or whether they are displayed or not.

Good Morning,
I have a problem with vfw (Video for Windows) and could need some advices.
I tryed to catch a single frame from a webcam.
I've got not much experience in programming with visual c++, i would be very thankful for any help.

The Code looks like this:

HWND hwndVideo; // Is a global Variable

//create capture window
hwndVideo = capCreateCaptureWindow((LPCWSTR)"WebCam", WS_CHILD | WS_VISIBLE, 0 ,0, (int)640, (int)480, m_CamWnd, (int)3);

//start the Preview
capPreviewRate(hwndVideo, 20);
capPreview(hwndVideo, true);

//I tryed to get the frame with capGrabFrame, but i wasnt able to get the framedata.
capGrabFrame(hwndVideo);
// or
capGrabFrameNoStop(hwndVideo);

How can i get the framedata to work with it??? Confused | :confused:

Echoes of MSDN?

Currently I want to look at MSDN Library http://msdn.microsoft.com/en-us/library/default.aspx[^] and it is not answering.

(1) Where is an echo of MSDN Library nearer to England?

(2) Where and what price can I get a full copy of MSDN to put on my computer?

(1) As far as I know there isn't one. If MSDN is down it won't be for long as MS will be getting a severe ear bashing from a lot of people who pay for support.

(2) Anyone who'll sell you MS products, I'm not going to post an ad here, should be able to sell you an MSDN subscription at anything from a few hundred GBP a year to $3000 depending on what you want. CDs/DVDs will arive in the post quarterly or perhaps even more often Big Grin | :-D

Try replacing en-us with en-gb in the URI, and you should get the UK mirror.

You can rename the file, but cannot delete it while executing.
Shocking for me too! OMG | :OMG:
