Registry backup/restore

I would like to write a routine to copy registry entries into an INI file then back into the registry, but the only functions I can find in CWinApp are WriteProfile and GetProfile. Does anybody know if there is anything built-in for this task or if it must be done manually??

Any suggestions are appriciated.

Thanks!

unfortunately, there is no any appropriate functions in MFC for your task.
Moreover, MFC does not include any routines for INI-support (as far as i know). You must do it manually, by WinAPI functions.

See in MSDN: RegOpenKey[Ex], RegCloseKey and so on for Registry operation

AND
GetProfileInt, GetProfileSection, GetProfileString etc. for INI-operations

There is an another way to solve your problem. You may use regedit with command-line params for saving and loading your data from reg-file. Like that

regedit /e My.reg HKEY_CURRENT_USER\Software\My Data //From registry to file

regedit -s My.reg //From file to registry

You can use WINAPI - CreateProcess function to make this job silent

but the Cursor doesn't change.

How can i make it the right way ?

to change the cursor, you need to handle the WM_SETCURSOR message. this will give you a OnSetCursor function.

like this:

BOOL CPickAxeView::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message) 
{
	// make sure we only set the cursor if we're need to 
	if (pWnd==(CWnd *)this) 
	{
		if (nHitTest==HTCLIENT) 
		{
			if (message==WM_MOUSEMOVE) 
			{
				SetCursor(AfxGetApp()->LoadStandardCursor(m_cursor));
				return TRUE;
			}
		}
	}	

	return CView::OnSetCursor(pWnd, nHitTest, message);
}

-c

Thanxs,

i needed for the header of a listcontrol. If the cursor is over the header,
then the standard cursor is shown.
How can i catch the Listcontrol->Header->OnSetCursor routine ?

you'll need to create a class derived from CHeaderCtrl, override OnSetCursor there, then use that class on your list control.

Yes.

Follow this path:

Project->Add to project->Components and controls->wait....->visual C++ components->splash screen.

You will get standard implementation of Splash screen.

Urgent help needed with MultiMap!!!

Anonymous15-Jul-02 3:21

15-Jul-02 3:21

Hi,
I'm new to STL, and got into some problem with it.
I need to use multimap, where "Key" is of type "long" while the "Data type"
is a "structure", which contains 3 items, including the "Key".
And later on will add insert/remove/... items from the map depending upon
the value of "Key" and a comaprision function.
I'm not able to do so, while inserting an item into map using "pair" it is
giving error: -
pair<int,struct mytest="">::pair<int,struct mytest="">' : none of the 2 overloads
can convert parameter 2 from type 'const int'

The syntax I'm using is something like this: -
typedef struct mytest{
int size;
int index;
int value;
};
...
multimap <int, mytest="">mymap;
mymap.insert(pair<int, mytest=""> (200, (200, 13, 868)));
...
Any help on this will be greatlly appreciated.
Thanks in advance!!

regards,

You need to create an instance of the struct and pass it in, what you are trying to do cannot work. What if you had three classes that all took three numbers in the constructor - how is C++ to know which one you want ? I dunno if mymap[200] = mymytest; will work for a multimap, but it's much neater for maps, that's for sure.

Urgent : Help with Visual Studio .NET C++ addin

Hi !

I'm working on a Visual Studio .NET addin written in C++. At the momment, the addin creates a new solution, adds a blank project to this solution, and adds folders to this project.

The problem is that when I try to add some files in one of the project folders, they are always added at the root of the project, and not in the specified folder.

Does anyone had the same problem ?
Is there a way to bypass it ?

Thanks a lot,
Jean-Paul
