ok, I understand...
My problem now is that I don't know which is the main procedure in the application... I'm working in Visual C++ and my app is called Window (I only wrote /ENTRY:WinMain so I could know if I had understood you).

Thank you.

Try changing the .mak file to the following in hopes of narrowing down which of the three modules is causing the problem:

todo: cliente.exe<br />
 <br />
cliente.exe: cliente.obj imevoc.obj<br />
link.exe cliente.obj imevoc.obj TAO_Portableserver.lib TAO_RTEvent.lib TAO_CosNaming.lib TAO.lib ace.lib /libpath:"C:\corba\ACE_wrappers\LIB"<br />
 <br />
cliente.obj: cliente.cpp imevoc.h <br />
CL cliente.CPP /MD /W3 /GX /O2 /I "C:\corba\ACE_wrappers" /I "C:\corba\ACE_wrappers\TAO" /I "C:\corba\ACE_wrappers\TAO\orbsvcs" /D "WIN32" /D "NDEBUG" /D "_WINDOWS" /D "_MBCS" /FD /c<br />
 <br />
imevoc.obj: imevoc.cpp imevoc.h<br />
CL imevoC.CPP /MD /W3 /GX /O2 /I "C:\corba\ACE_wrappers" /I "C:\corba\ACE_wrappers\TAO" /I "C:\corba\ACE_wrappers\TAO\orbsvcs" /D "WIN32" /D "NDEBUG" /D "_WINDOWS" /D "_MBCS" /FD /c

If this works, do the same for servidor.exe, and then servidorv.exe.

servidor and cliente are OK.
Which could be the problem?

Do any of the following modules contain a WinMain(), or equivalent, function:

ventana.cpp
ventanaDlg.cpp
imevoc.cpp
imevos.cpp
imevo_i.cpp
imevo.cpp

I think so since I've created the ventana.dsw project and in other projects I had no problems, but I don't really know which is the function that begins here D'Oh! | :doh:

When I build my project in Visual C++ instead of DOS console with nmake, I get this different message error:

<br />
ventanaDlg.obj : error LNK2001: unresolved external symbol "protected: virtual void __thiscall CVentanaDlg::OnOK(void)" (?OnOK@CVentanaDlg@@MAEXXZ)<br />
Release/ventana.exe : fatal error LNK1120: 1 unresolved externals<br />

The error that I get in the DOS console is about the entry point as I told you... I can't see the relationship between these errors.

Waiting for your help and knowledge Smile | :)

Thanks!

Why don't you open the ventana.dsw workspace, click on Project/Export Makefile. Compare this .mak file with the one you are currently using. Notice that it probably contains a lot more .cpp files.

controlling a webcam

Hello,

I need to control a webcam and analyze picture by picture (and pixel by pixel) but I do not really know where to to start. Do you have to have the manufacturers API or is there any windows standard interface that you may use? Can you use VC++ or VB classes? Do you poll frame by frame or do you get a continuous stream? What format would you expect to get on the pics/stream, complete pics or changes? etc etc.

Thanks for any help I may get.

There are lots of options that are set in project settings, things like INCLUDE paths, DEFINE-d symbols, and the like.

You say it doesn't do it, but you aren't giving any clues as to what errors you see.

Listening to Keyboard Input

0v3rloader24-Mar-04 5:29

0v3rloader

24-Mar-04 5:29

Hello,

I was wondering if anyone here knows how to listen to keyboard input in Windows platform by means of using MFC.

To be more exact, whenever this specific application of mine is running, CTRL + DEL (among other keyb combinations) cannot reach the OS and must be filtered by the App, which will prevent the user from invoking Task Manager / Logging Off / Shutding Down (though there is always Reset/Power Off), etc.

Any idea would be much appreciated.

Read about hooking starting from SetWindowsHookEx using WH_KEYBOARD_LL hook type.
You can hook ALT+CTRL+DEL by i think that the OS won't let yu block it. The dialog will be opened anyway.
However,you can disable the buttons of the opened window by setting some values in the registry Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\Explorer.

Thanks a lot for the reply. I have heard certain OSes do not allow you to have full control over the CTRL+ALT+DEL feature.

However, what's so important about the app ?
Well I have an app which needs to be invulnerable to the more naive (or ignorant, should I say) users because some extremelly important analysis & update process has to be carried out and whilst it is being done, no keyboard input should be allowed.

Does anyone have any ideas as to what I should do?

Thanks very much for the replies. Big Grin | :-D

If it's NT, 2K or 2.03K, you can't do it that way, the SAS will always be picked up, for obvious security reasons. If it's Win9x/ME then it is simpler.

C++ Generic Autorun app ?

Hi , I've been searching the internet and CodeProject but I haven't found any customizable autorun app , All we know autorun dialogs present in every Microsoft CD . I'm a C# programmer and I don't have good c++ skills I'm sure that lots of programers like my are looking for some solution does anyone has any code to share ?

Thanks,

Re: C++ Generic Autorun app ?

There is basically a Autorun.inf file in the root directory of the CD containing the name of a program to run when the CD is inserted.
This can be prevented by holding down the 'shift' key when inserting the CD. Also, it does not work with operating systems other than Windows.
I thought I just say that, because recently some very smart guy (SunnComm Technologies) invented a CD copy protection scheme on autoloading a program that prevented access to the CD. They sued the one who found out: Link here Roll eyes | :rolleyes:

_control87 and signal(SIGFPE....)

prcarp24-Mar-04 3:03

24-Mar-04 3:03

I have a very large mathematical model that runs continuously. I am trapping for math errors via _control87(_EM_INEXACT, _MCW_EM) and signal(SIGFPE, MyFPHandler). This part works and my routine (MyFPHandler) is called whenever there is a divide by zero, invalid operation, etc.. What I would like to do is get the program location of the offending operation. Is there a way to do this? The code must know somehow because, if I wanted to, I could resume execution from that point. However, in my case, I do a an _fpreset, and then longjump to a safe area that does some simple error reporting and cleanup.

Thanks,
Paul

Hi I have a problem where I cannot use GetDIBits on 98, works fine on XP. I read somewhere that in 98 the width and height have to be divisable by 4 so I even tried that with no avail.

Here is a snippet which works in XP but doesn't in 98. Has anybody got any clue why it's not working in 98

<br />
        <br />
        ...<br />
<br />
	HDC hBmDC = CreateCompatibleDC(NULL);<br />
	HBITMAP hB = CreateBitmap(16,16,1,24,pPixels);<br />
<br />
	bmiInfo.bmiHeader.biSize = sizeof(BITMAPINFOHEADER);<br />
<br />
	// get pixels from the original bitmap con verted to 24bits<br />
	int iRes = GetDIBits(hBmDC,hB,0,16,NULL,&bmiInfo,DIB_RGB_COLORS);<br />

Help - CPrintDialog as a child

Jason Carter24-Mar-04 2:41

Jason Carter

24-Mar-04 2:41

I am trying to use the CPrintDialog functionality, with my own template, as a child on a tabbed dialog in VC6. If I make the child dialog a CPrintDialog it does not initialise with the printer details. So I tried to make the Main dialog a CPrintDialog, still the child does not respond. I then put the Controls on the Main dialog, then MoveWindow them to the Child, this inits ok but no longer responds to any user interaction ( change of printer combo ). I have played a little with message routing and can now respond to combo change, but not Properties Button. Anyone any thoughts

Overloading operator [ ]

Imtiaz Murtaza24-Mar-04 0:58

Imtiaz Murtaza

24-Mar-04 0:58

What is the correct method to overload the operator []. I am doing something like:

class MyClass
    {
      
      const int operator[](const int i ) const;
  
      int& operator[](const int i );
      //...
    }

Now i want to invoke the operator [] as follows:

MyClass foo;

    int i = foo[j]; 
    foo[j] = i;

Strange that in both cases second operator of the above class always gets called. Can anyone tell me whats the problem and why not first operator gets called ??
