How can I rename an NT user using the ADSI(Active Directory Service Interfaces)? The IADs::SetInfo method can only change user's fullname not rename a user.

hi all!
Mu problem is to draw the scrolbars on my application.
It is realized with mfc and it is MDI.

I wanto to draw the scrollbars on the child window when I load an image larger than the window.

I try to edit code in the ChilFrm.cpp file and i wrote this:

BOOL CChildFrame::PreCreateWindow(CREATESTRUCT& cs)
{
if( !CMDIChildWnd::PreCreateWindow(cs) )
return FALSE;
cs.style |= WS_VSCROLL | WS_HSCROLL;

return TRUE;
}

In this way the two scrollbar appear, but they don't do anything.

can you help me?

thks a sorry for my english

yes it will coz you are enableing both the scroll bars...

you need to use setscrollrange method to start working on the scrollbar...

ok, i added the setscrollrange function to my code for both scrollbars.

Now i want the they appear only when i load an image that is larger than the window. I see that exist the ShowScrollBar function, but it give me a runtime error, always!I put the code in the precreatewindow of the childFrm class.

can you explain me? Confused | :confused:

Toolbar flicker

I am using the Win32 toolbar common control in some code. When I resize the window that the toolbar is parented to it flickers. Is there any way to stop this?
The toolbar's parent window is created with no brush, and returns false for WM_ERASEBKGND. Is there some thing special about the way I need to handle the toolbar itself?

Thanks

Check that your main window has the WS_CLIPCHILDREN style.

I checked, and all of my controls have the WS_CLIPCHILDREN bit set, the main window, and the any custom child control's that get created (the toolbar's parent is a custom child control)

Hey there

I've just started to learn programming and using visual basic 6 (teaching myself) would really appreciate it if someone could explain to me how it is that variables work and exactly how to use them as this part has got me stumped.

Thanx a million

since this is a VB6 Q.
you should send it to the vb forum not vc++

anyway :
you use variables to store some data in memory for processing...

for example..

dim a as single
dim b as single
dim c as single 'here i made 3 place holders in memory for single variables.

a=CSng(Text1.Text) 'read data from Text1 into memory location called a
b=CSng(Text2.Text) 'read data from Text1 into memory location called b
c=(a+b)/2 'get the avarage of the two numbers and store it in c for latter use

MsgBox c 'use the variable c

You have asked this question before. A quick look in MSDN will reveal a host of functions that you could use to find the CWnd pointer to the window you want to send the message to. Look up CWnd, CFrameWnd, CSplitterWnd, CView, and CDocument. Read what each of the member functions does, and find the ones that will do what you want.

I have had to use the CBS_OWNERDRAWVARIABLE style instead of the CBS_OWNERDRAWFIXED style to get the DrawItem function to work. I do not know why CBS_OWNERDRAWFIXED did not work.

Hi,

I want to use SMTP (sendmail) to send email where the body is an HTML document rather than plain text, is this possible and if so how do I go about doing it? I haven't been able to find any sample code other than plain text emails.

Regards

Robert Cooper

HTML is "plain" text, you send it the same way as an unformatted text message. Just change the "Content-type:" header from "text/plain" to "text/html".

problem with dll

In a dll, I define a class in the following way:

<br />
class _declspec(dllexport) jalla {<br />
	std::list<int> m_mesh;<br />
};<br />

but when I try to compile it, I get the warning:

<br />
e:\Work\C++\Project\3DGame\3DSLoader.h(19) : warning C4251: 'jalla::m_mesh' : class 'std::list<_Ty>' needs to have dll-interface to be used by clients of class 'jalla'<br />
        with<br />
        [<br />
            _Ty=int<br />
        ]<br />

what is happening?

It means that the instance std::list<int> needs to have a dllexport attribute on it in order to be safely usable by clients. Just like you are tagging jalla with dllexport.

As you may understand, exposing STL datatypes through a DLL interface is not easy. I don't know any good workarounds for it, other than using a non templated and exportable type/class. Sorry. Frown | :(

Im trying to find a good way to minimize a game(full screen) when I press a key combination like alt + tab, but it needs to workin in windoes xp. I can't seem to find an appropriate function to use for this. any suggestions?

Re: Minimize another app.

Archer28225-Jun-04 20:05

25-Jun-04 20:05

You can use GetAsyncKeyState() or GetKeyState() to test for th keys

then you can GetTopWindow() or GetActiveWindow() something like that i dont remember which it is
to get a handle to the active window,
and then call CloseWindow() (it doesnt actually close it it just minimizes it)

if you need help with it just let me know, it shouldnt take me a few minutes to write the whole thing

Ok well im getting somewhere but not quite doing what i need. Here is what im trying to do:

Build a simple app the runs in the background while I play a full screen game. The game does not have an minimize ability. So I want to have my app minimize the game when I press Ctrl+Z.

So far I have been able to get it to work (sort of) but only for windows and not the full screen game that I want to minimize. I'm using GetAsyncKeyState() to test the keys and GetForegroundWindow() to get the handle to the active window then just use CloseWindow() to minimize. But this does not seem to work for full screen apps. Any suggestions?
Thanks for the help.

Well, you could also use ShowWindow() to hide and show it,

here is what i would do

in the main thread set a HWND variable to 0 by default, continously loop and test for CTRL+Z

if CTRL+Z is pressed and the variable is 0, then call GetForegroundWindow() and store its hwnd in the variable, and hide the window
if the variable is not empty then show the window and set the variable back to 0

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
