A and B are correct.
Just for your knowledges as well, the modal dialog in MFC is different than the modal dialog that you will get with the Win32 API. That is because of that function that you found, RunModalLoop(), MFC creates its own message pump to handle all of the messages, which allows the rest of the app to intervene if necessary, MFC is able to accomplish this because it always creates its dialogs with CreateDialog rather than DialogBox. If you call DialogBox in the Win32 API, windows will create their own modal message pump for you.
Coincidentally this is how the processing for menus works as well, there is a modal message pump involved.

Is there anyway in code to create a file association. i.e. I want to associate a file type of .log with notepad. I know how to do this via Windows explorer, can I do this at runtime?
Thanks in advance,
Bob

You can create registry keys at HKEY_CLASSES_ROOT.
Create one for the file extesion (Ex.: .log) and put as default value a mime type (Ex.: text/plain). If the mime doesn´t exists you can create another key at HKEY_CLASSES_ROOT with a subkey shell\open and put the command to open the file there.

Ha ha, I know it sounds strange, but I still need it to drop the list when the user clicks the box or hits F4, I just can't get the boxes to fit where they need to without getting rid of the button somehow. I am dealing with a screen drawn for a character based program and I have to use the same layout so my space is limited.

you would need to do subclassing already.
how about checking this out.

Hi,
Is there any way I can convert a HRESULT to the "errorcode string"
I mean, the HRESULT 2147746132 means "Class not registered", is there any functions that takes a HRESULT and gives me a string with the error text?

FormatMessage API function will works with predefined HRESULT.
Philippe Mori

From MSDN Q169498:
// Obtain the error message for a given HRESULT
CString LogCrackHR( HRESULT hr )
{
LPVOID lpMsgBuf;
CString strTmp;
::FormatMessage( FORMAT_MESSAGE_ALLOCATE_BUFFER |
FORMAT_MESSAGE_FROM_SYSTEM,
NULL,
hr,
MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),
(LPTSTR) &lpMsgBuf,
0,
NULL );
// STR_TMP is defined within LOG.CPP to provide safe format string
// for both ANSI and UNICODE
strTmp.Format( "%s", (char *) lpMsgBuf );
// Free the buffer.
::LocalFree( lpMsgBuf );
return strTmp;
}

I'm subclassing a static control. I would like to get the mouse click messages but they don't seem to get generated. I get them if I subclass from a button.

Mamke sure the static control resource on the dialog has the Notify style set to be able to get mouse messages.

I created an ATL DLL server project and inserted a new ATL object as a simple one, named Inter. Next, i added a new BSTR-type property named Str.
I wrote:
STDMETHODIMP CInter::get_Str(BSTR *pVal)
{
_bstr_t x(*pVal, FALSE);
m_str=x.copy();
return S_OK;
}
This code links perfectly on debug versions but generates this error:
LIBCMT.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
on release versions.
Do you know how to handle it?

This is straight from MSDN, help topic _ATL_MIN_CRT :
Note When building a Release version of a project, you can get the following link error:
LIBCMT.LIB(crt0.obj) : error LNK2001: unresolved external symbol _main
This error occurs if you are using CRT functions that require CRT startup code. The Release configurations define _ATL_MIN_CRT, which excludes CRT startup code from your EXE or DLL. To avoid this error, do one of the following:
Remove _ATL_MIN_CRT from the list of preprocessor defines to allow CRT startup code to be included. On the Project menu, click Settings. In the Settings For: drop-down list, choose Multiple Configurations. In the Select project configuration(s) to modify dialog box that appears, click the check boxes for all Release versions, and then click OK. On the C/C++ tab, choose the General category, then remove _ATL_MIN_CRT from the Preprocessor definitions edit box.
If possible, remove calls to CRT functions that require CRT startup code and use their Win32 equivalents. For example, use lstrcmp instead of strcmp. Known functions that require CRT startup code are some of the string and floating point functions.

yeah, the line of code is
HINSTANCE nRet = ShellExecute(this->m_hWnd, "open", szBuff, NULL, NULL, SW_SHOWNORMAL);
where szBuff is a string variable which contains the full path of the file name and the file name itself.
Thanks!

Maybe you could try to start by specifying WS_EX_TRANSPARENT sty;e when creating your windows. That ways, Windows will paint Windows behing yours first...
But it will not works as smootly as it does in Windows 2000 for few reasons:
- I'm not sure that it apply to non-client area.
- It will causes blinking
- It will probably be slower (particulary when movig full window)
- It's probably a bit bugged and/or limited.
You may also try to enumerated windows behind you and cause them to be paint in a memory DC. It will probably works for some kind of windows and not for others...
