Actually it does, however it is optional:
PXSTR PlzGetBuf(BOOL bUrgent = TRUE);

I have to make a login screen for my application. and how do i do validation for this? the application that i am planning to do is an MDI. now the first thing when the exe is called the login screen should appear. so where should i call this dialog box?
if somebody can give me a link tht will lead to an example that would help me a lot.

It could be the first window you create and show, or you could create your "main" window
hidden and show the dialog after creating the main window.
Same as creating any window - you control when windows are created and made visible.

ok.. let me make it more clear..
when u click the exe the first screen tat will appear will be the login screen.. once the login and password is right the applications first window appears..
i hope its clear.. and i could not find any articles with login and password examples.

That's clear.
What's not clear to me is what you're having trouble with.
You can pop up a modal dialog when your app starts running.
If the login fails you exit the app or loop and show the dialog again.
If the login succeeds, create the MDI window.
That's one way to do it. FWIW, that's what I do in my apps.

Using DoModal() . I think you should read about creating a dialog
Somethings seem HARD to do, until we know how to do them.

i am aware of DoModal function.
i want a dialog box which pops up when the MDI application.exe is clicked. only once the login and password is correct the control should go to the application.

How many times does he have to tell you the same thing?
If you're aware of the DoModal member function of a CDialog, then go ahead and use it. Fail. Change your code again, try!
What I did not see in your questions was any evidence that you have tried and failed to do anything. People come here to help, not to bottle feed.
BOOL CMyApp::InitInstance()
{
... some initialisation code?
CMyPasswordDlg dlg;
if (dlg.DoModal != IDOK)
return FALSE;
CMainFrame* pMainFrame = new CMainFrame;
if (!pMainFrame->LoadFrame(IDR_MAINFRAME))
return FALSE;
m_pMainWnd = pMainFrame;
... etc as normal
return TRUE;
}

ps, No, I'm not coming to your workplace to type it for you.

i did try in my code.. but just that i dint tell u what i did and how i did. i dont expect anybody to bottle feed me.
well thanks for the help

Ok, glad to hear it - and I apologise a little. Did you progress further with the gappy code I showed you?
Iain.
Iain Clarke appears because CPallini still cares.

Have you even bothered to look in your app's InitInstance() to see what normally goes on during startup? Have you tried to call DoModal() somewhere in there?

Are you using MFC or straight Win32 APIs?

Ok, maybe I shouldn't, but you are the community I rely the most on,
so I'll make this attempt...
This is not a real C++ question (though my GetFileName.exe was built with it!)
I have an EXE files that gives a string output. If i write in dos prompt
set ans=GetFileName file.txt<br />
@echo %ans%
I correctly obtain
file.
If I write the same in a BAT files I retrieve
<br />
GetFileName file.txt
which means the cmd hasn't resolved the command.
What should I do to obtain the same result...?
Tnx a lot!

from memory (dim and dark recesses mind you) you'd have to do something like
for %%f in ('GetFileName file.txt') do set ans = %%f
@echo %ans
the single quotes around GetFileName file.txt are the dos equivalents of the unix back-tick (and yes the double %% signs are intentional)
Im not sure if the for stmt needs a /F or another switch though - maybe you can google something like 'dos batch for' ...
'g'

Typing for /? at a command prompt will suffice.

What OS are you using? I tried this and the echo statement printed what I would expect: GetFileName file.txt

Hi,
I'm looking for a way to change what this points to. I want to make a function that essentially does this = new InstanceOfAClass(value, this), for a linked list, but but I can't figure out how.
I feel like this is a pretty basic question, but I can't find the answer. Thanks,
-Ken

Assigning a value to "this" is no longer allowed.
You should be creating new object instances, possibly with the help of proper
copy semantics - assignment operator overloading and copy constructor.
