did you well think to set your edit as MultiLine ?

I need to use a single line but I want to process Enter key or the Enter key is disable.
Thanks in advance

hum, you mean to have a default button which is enable or disable depending on the content of your editbox ??
use EnableWindow() to Enable/disable your button
use SetDefID() to tell the dialog which button would be the default one (that would be clicked if Enter is pressed)

Right click on your Edit Box and in the properties dialog box mark the "WantReturn" and "Multiline" checkboxes.

I use only a line, but I like to disable the Enter key.

Overload the OnOk message handler , do next :
void CYourDlg::OnOK()
{
//CDialog::OnOK();
}
the problem is that OK is set to default button and when you press Enter , automatically OnOk event handler is called.
Note that if you have only deleted the Ok button ,without doing what i wrote above , it does not solve the problem.
In this case you will have to drop any button make it "Default Button" and "Invisible", .

bad coding...
moreover, if you have to change the default button programatically (when the code executes), how will you do ? - i doublt you can like this...
use CDialog::SetDefID() instead into OnInitDialog()
CDialog::SetDefID()
this->SetDefID(IDC_BUTTON1);

Can you tell me the better way of doing this ??
when the OK button is already deleted

the enter key functions as a button-press.
Probably the OnOk of your dialog is being called when you press enter, and the default action of OnOk is to close the dialog.
What you can do is capture the VK_RETURN event in your edit control and e.g. do nothing or translate it to VK_TAB...
You could also capture the VK_RETURN in your dialog offcourse and not have it execute the default behaviour.
Hope this gets you along,

Hi,
My application calls the SearchPath() API in a method which gets the version info of a file. On execution, the UNICODE debug version of the application always crashes. The error shown is 'Unhandled exception in MyAppl.exe (NTDLL.DLL): 0xC0000005: Access Violation'. The MBCS/UNICODE Release build of the application works fine and also the MBCS debug build.
<br />

}<br />

{<br />
return(ERR_FILE_NOT_FOUND);<br />
}<br />

}<br />
The function call is
TCHAR tmp[1024];
GetModuleFileName(NULL, tmp, sizeof(tmp));
getFileVersionInfo(tmp);
Am I missing out something here? I have Win2K OS. Please help.
Thanks,

The third parameter is the number of characters, not the size of the buffer in bytes. You'll need to pass in 1024 to indicate there are 1024 characters (or sizeof(tmp)/sizeo(TCHAR))
Vinaya wrote:
SearchPath(NULL, FileName, NULL, sizeof(pathBuffer), pathBuffer, NULL)
Ditto for the fourth parameter here.

Your exception is basically caused by the sizeof() input parameter of the function. This parameter required the number of characters that your string buffer holds. But the sizeof() function returns the number of bytes within the array. With a UNICODE program, each character occupies two bytes, so will therefore return twice the number required, resulting in a memory exception.
Try:
<br />
if (SearchPath(NULL, FileName, NULL, sizeof(pathBuffer)/sizeof(TCHAR), pathBuffer, NULL) > 0)

Hi,
I've to capture the handle of the window, i knew the process id of the window, how to capture the window handle using the process id. Anyone pls provide me solution to the problem.
Thanks & Rgds

You could use EnumWindows.
In the EnumWindowsProc call GetWindowThreadProcessId and compare the process id with the one you have, if they match then that window belongs to the process in question.
You should be able to build up a list of all the windows that belong to the process.

Shouldn't you be looking at CDaoException or CDBException to see why the Open() call failed?

Hey,
can you tell me why SetButtonInfo has no effect in a CFormView. I first created a Dialog (CDialog)with a embedded Toolbar. In this case I used SetButtonInfo to enable/disable ToolbarButtons. Now I created a Dialog derived from CFormView. When I now use SetButtonInfo the button "flickers" shotly but nothing else....
Do I have to create a
ON_UPDATE_COMMAND_UI function and a status-variable for each ToolBarButton in my CFormView class, or is there an easier way?
Thank you all....

Yes and No. You're better off to use ON_UPDATE_COMMAND_UI, and compared to that method, all other possible solutions are painfully difficult.

Hello.
please, help me with this problem.
the program is to parse HTTP messages. From the RFC 2616 (HTTP/1.1):
"The HEAD method is identical to GET except that the server MUST NOT
return a message-body in the response. The metainformation contained
in the HTTP headers in response to a HEAD request SHOULD be identical
to the information sent in response to a GET request."
It means the response will inlude the Content-Length header but will have no body.
How to differ response on HEAD method and on GET?
While the connection is persistent the client can send a lot of HEAD requests one by one or in another order. The headers of these (GET and HEAD) responses are identical,but in case of HEAD the parser must not parse message-body.
How to differ them?
Thank you.

How does one convert from CComBSTR to std::string? With std::wstring it is LPCWSTR(CComBSTR), but for std::string I get a lot of error messages
I am the handsome one in the crowd.

I suspect that these 'errors' have a lot to do with the differences in the character types (ANSI and Wide character types).
See this[^] MSDN article. This may help you find your solution.

Is it possible in an MFC/MDI application to prevent the last window from being closed e.g. if someone accidentally clicks the 'X' on the lat window?
