Is there any reson for using this API ? Its documentation says, Creates a bitmap for use in a toolbar.

I've been using VC++ 6 and office 2003 for a long time without any problem.
But when I install office 2007, my VC++ 6.0 cannot open file or add file to existing project, but it's still able to open workspace, create new project, compile, run, ... do everything else perfectly !!! But any time I choose File/Open or Project/Add to project/Files then visual C shutdown immediately without saying anything !!! It just closes like it was killed !
Uninstall office 2007 and things go back to normal.

Have any one suffered the same situation ??

Try to include Winbase.h in your source file.

EVC compiler . Am using a device ,and the specific SDk of the device .In that sdk the winbase.h file does not contain this function GetSystemPowerStatusEx2 . Is there any other way to find the battery level ?

Did you see MSDN
To compile an application that uses this function, define the _WIN32_WINNT macro as 0x0400 or later

Have look at this[^] FAQ, by Michael Dunn.
Define _WIN32_WINNT accordingly, make sure, you have latest platform SDK installed.

You are using very old header files. You need to download the latest SDK.

Check the FAQ article by Michael Dunn.

Hi,

You can define a variable for an edit control of type double. There is a field in the Add Variable wizard that allows you to select the target type.
If you still remain with the CString variables, than;

double d1 = _tcstod(m_strMyEdit1, NULL);
double d2 = _tcstod(m_strMyEdit2, NULL);
double res = d1 + d2;
// Now to fill the resulting edit control
CString sRes;
sRes.Format(TEXT("%f"), res);
// Either this ..
m_strResultEdit = sRes;
UpdateData(FALSE);
// .. Or this ..
GetDlgItem(IDC_MYRESULTEDIT)->SetWindowText(sRes);

See the atof function documentation [^].

Note that, Thanks to the provided CString::operator LPCTSTR, you can directly apply atof to a CString variable, for instance:

CString sMyData;
float fMyData;

sMyData = "5.375";
fMyData = atof(sMyData);
