how we add WM_TIMECHANGE message to our project please tell me
vsn
|
|
|
|
|
In the header file declare
afx_msg void OnTimeChange();
In .cpp file
void CTEstDlg::OnTimeChange()
{
CDialog::OnTimeChange();
}
And in the begin message map section do this
ON_WM_TIMECHANGE()
Somethings seem HARD to do, until we know how to do them.

If it's an MFC application, use ClassWizard (Ctrl+W). Adding all of the pieces manually will work, but there's always the chance you could miss something.

Right Click on the dialog . Go to properties>Styles Tab and select the minimize box (check box) option. That's it

we created the dialog in win32 application using CreateDialog. In the properties of dialog window, I set the Minimise Box to TRUE. But the minimise option is not coming.

You can go in the resource editor and open the properties window for the dialog. There should be a tab where you can add a title bar and add a minimize and maximize button (don't remember exactly the name of the tabs, so you have to look a little bit by yourself).

This will delete a directory and all of its contents:
static BOOL DeleteDirectoryPath(const CString& path)
{
// Function to delete a directory, including the case where
// files and sub-directories exist. Also deletes the name specified,
// if it is actually a file.
WIN32_FIND_DATA find;
HANDLE findHandle;
CString file, filePattern;
DWORD fileAttrib, err;
filePattern = path + "\\*.*";
findHandle = FindFirstFile(filePattern, &find);
while (findHandle != INVALID_HANDLE_VALUE)
{
if ((strcmp(find.cFileName, ".") != 0) && (strcmp(find.cFileName, "..") != 0))
{
file.Format("%s\\%s", path, find.cFileName);
if (find.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
{
if (! DeleteDirectoryPath(file))
{
return FALSE;
}
}
else
{
SetFileAttributes(file, FILE_ATTRIBUTE_NORMAL); //Prevents some deletion failures
if (! DeleteFile(file))
{
return FALSE;
}
}
}
if (! FindNextFile(findHandle, &find))
break;
}
FindClose(findHandle);
fileAttrib = GetFileAttributes(path);
if (fileAttrib == 0xFFFFFFFF)
{
err = GetLastError();
if (err == ERROR_FILE_NOT_FOUND)
{
return TRUE;
}
else
{
return FALSE;
}
}
else if (fileAttrib & FILE_ATTRIBUTE_DIRECTORY)
{
if (! RemoveDirectory(path))
{
return FALSE;
}
}
else
{
SetFileAttributes(path, FILE_ATTRIBUTE_NORMAL); //Prevents some deletion failures
if (! DeleteFile(path))
{
return FALSE;
}
}
return TRUE;
}
cheers,
Neil

Hi previously my code is building fine.But now it is showing many errors like
integrator\item.h(52) : error 2039: 'iterator_facade' : is not a member of 'boost'
integrator\item.h(52) : error 2504: 'iterator_facade' : base class undefined
iam using Boost library.
All project setting are ok.
Ur experiance might be so useful for me.
Thank u.

Did you include the header file where this class is defined into the source file in which you are using it ?

I have added already
#include "boost.h"
|
|

I suppose iterator_facade is not defined in boost.h. Looking at this page[^], it seems that it is defined in <boost/iterator/iterator_facade.hpp>.
I suggest you read the documentation first, normally, everything should be explained there (I suppose, I never used boost before).

You should; it takes C++ to a new level. I've learnt a lot about C++ by simply reading the Boost documentation.

Yes I know. I plan to do that when I have a little more spare time (which I don't know when )
