Ahhh, of course. Thank you very much. Now I'm receiving a new error.

Cannot open include file: 'winsds.h': No such file or directory

This must be specific to the dll I'm loading.

Thanks for your help. I was looking for a tough solution.

Hi,

I have a questionr regarding the useage of a virtual list control.

I keep all my data in my own array.

From time to time, the data in my array changes.

How could I make these changes reflected on the vlist control?

Jeremy.

Hello, i've just started C++ and currently looking into MFC. Smile | :)

Is there a way that i could convert my existing console app to a MFC app?....because i wanted a GUI as well as a console window.....i tried adding the stdafx.cpp and the header file , the preprocessor def: _WINDOWS,_AFXDLL to my existing project. when compiled....i get......"c:\program files\microsoft visual studio\vc98\mfc\include\afxver_.h(130) : fatal error C1189: #error : Please use the /MD switch for _AFXDLL builds". Frown | :(

Please Help!!! thanx

The easiest way is to make a new dummy console project with the AppWizard, then copy the MFC includes and startup code (eg AfxWinInit()) to your app.

who can tell me how to save the DC...

i mean that i draw something on a DC(CDC).
then i need to save this to a .bmp file.
that is to say, how to find the BITMAPINFO structure?

Re: who can tell me how to save the DC...

You must compute the bitmapinfo structure in your program. This is a "To Do". Read the MSDN and don´t ferget the 'DWORD' Alignment!!!

Try this @ home. (B&B)

Thanks.
Can you tell me where I can find the details about this in MSDN?
And how can i compute the bitmapinfo structure about a DC?

Best Regards...

If you use the visual studio press F1 else try the online docs from MSFT.
If you 'maybe' find the bitmapinfo you will read that this info contain the measures about the bitmap. A nice function is also "GetDIBits".

Try this @ home. (B&B)

ok.Thanks.
I have download a program coding with VC++6.0,
It use GetDibits() function as you say.

Now,i will study these documents and functions at first... thanks you very much..

About a time event

I have a thought to make the speaker to speak at a special time. That is:
1.Set RTC timer alert time at a special time;
2.Then the RTC timer triggers the speaker to speak.

This action can be done by Api functions "CreateTimer" and "OnTimer".
But I don't want to use this way, how to do it?
I use VC6.0

Thanks in advance!

Use the shell to start a batch-file at your specific time?

Well, you simply need to get a batch-file to do what you want (e.g. reading a text or playing a *.wav).
Then you can use "scheduled task" to start that .cmd at the time you want.
Please read the help about scheduled tasks, as I am no expert, just a user.

direct draw and multimon problem

gwenael28-Sep-03 22:07

28-Sep-03 22:07

I have a Video system and I want to display permanently images that come from it when I run my application. Solution seems to be Direct Draw with 2 graphic board or a DUAL one. It is not really a problem, I suceed. But, there is a point that worry me. It is obvious that when my application is running on one monitor we will display video image and on the other normal interface and I'd like seeing mouse only on the normal inteface. But if we attach all the graphical boards to the desktop the mouse is moving on the 2 screen, I am afraid that is too confusing for customer. I'd like then use one board attach on the desktop (we need at least one anyway) and the other is sleeping, excepted when my application is running then it will display video. In term of programing that means we need to call Direct draw with the good board device. the function DirectDrawEnumerateEx is all what we need. It works well if all the board are attached to the desktop (that is to say we see all the board device) but any of the boards are not attached then I don't succeed in seeing them. However there is a flag DDENUM_DETACHEDSECONDARYDEVICES that seems to be specially provided for that use but it do not return anything about the detached devices. Is anyone can help?

Accelerator keys in modeless Dialog?

Brian van der Beek28-Sep-03 21:53

I created a modeless dialog with an accelerator table, but for some reason PreTranslateMessage is not called, so my accelerator keys are not translated to messages. Anyone knows why PreTranslateMessage is not called, or how to solve this problem?

Re: Accelerator keys in modeless Dialog?

Phil J Pearson29-Sep-03 2:50

Call PreTranslateMessage yourself; it's virtual.

Something like this:

BOOL CMyModelessDlg::PreTranslateMessage(MSG* pMsg)
  { 
  if (!(m_hAccel && ::TranslateAccelerator(AfxGetApp()->m_pMainWnd->m_hWnd, m_hAccel, pMsg)))
    return CDiaog::PreTranslateMessage(pMsg);
  else
    return TRUE;
  }

I have something like you proposed:

<br />
BOOL CCentaurusDlg::PreTranslateMessage(MSG* pMsg) <br />
{<br />
    BOOL handled = FALSE;<br />
<br />
    if (pMsg->message == WM_KEYDOWN)<br />
    {<br />
         if (::TranslateAccelerator(m_hWnd, m_accelerators, pMsg) != 0)<br />
         {<br />
            // the accelerator was handled<br />
            handled = TRUE;<br />
         }<br />
    }<br />
    <br />
    if (!handled)<br />
    {<br />
        // let the dialog handle the message<br />
        handled = CDialog::PreTranslateMessage(pMsg);<br />
    }<br />
<br />
	return handled;<br />
}<br />

But my PreTranslateMessage method is not called by the MFC framework. So where should I call PreTranslateMessage?

"string" problem.

I feel my computer is playing a cat and mouse game with me, and I am the one losing. Here's why!

I can enter a bunch of strings and it can read one and ignore the rest, (meaning, it'll only give me the first one that it read), or it can read ALL, but give me NOTHING (meaning, it'll hang in the loop)!! Here's the code.

string str;
vector<string> vStr;
do
{
   cin>> str;
   vStr.push_back(str);
   cout<<"\n Size: " <<vStr.size();  //will show the vector growing
} while(str.end()!="\r");
======================
vector<string>::iterator iterB = vStr.begin(), iterE = vStr.end();
for(; iterB!=iterE; ++iterB)
    cout<< *iterB <<" ";
======================
cout<<"\n" <<endl;

The condition shown in the 'while' statement, will show the vector growing as strings are entered, but WILL NOT exit the 'do/while' loop.

However, if I were to change the condition in the 'while' statement to:

while(str.end()=="\r");

It'll exit the loop, but will ONLY give me the first string it read.

Ideally, I would like for it to read all the strings entered, and report all that it accumulated in the vector.

Thanks for any help.
