oops. looks like I was hitting build instead of compile.. it put the .obj file in a folder called debug.

Now I'm trying to figure out how to link that .obj file with the third file.

Hi there

How to convert double to int?
Q1:
if a double is smaller than 1.4, it will be assign to 1
Ex: 1.3 will be 1

if a double is bigger than 1.4, it will be assign to 2
Ex: 1.5 will be 2

Q2:
if a double is bigger than 1 and smaller than 2, it will be assign to 2
Ex: 1.20 will be 2
2.10 will be 3

Does anyone know the function?
Thanks.

Q1: Add 0.5 and cast to int.
Q2: (rounding up) is done bey ceil() (and ronding down by floor()).

They are discussed in this online manual[^]. It looks like a pair of headers for developing programs to use DB2 databases. If there's a developer kit for the product, they're probably included in it.

Program not responding?

I'm trying to write a peice of code to allow me to intercept the close command in the console attached to my application's process so it will prompt the user before destroying the process. Below is the function I wrote for this. It works fine, but the problem is that when the message box pops up it convinces windows the program has stalled, and an end task window opens. Is there any way to prevent this? If it matters, I'm only considering Windows 2000/XP compatibility for this app.

BOOL WINAPI ConsoleHandlerRoutine(DWORD dwCtrlType)
{

 int i;

 switch(dwCtrlType)
 {

 case CTRL_C_EVENT:
 case CTRL_CLOSE_EVENT:
  for(i = 0; i < (MAX_DASMS - 1); i++)
  {
   if(dasmDialogProcInfo[i].handle)
   {
    if( MessageBox(hWnd_console, "All work in open windows will be lost if you terminate the application. Proceed?", "Information", MB_YESNO | MB_ICONQUESTION) == IDYES )
     return FALSE;  //Don't handle this massage so the application will terminate normally
    else
     return TRUE;   //Handle this message and the application will continue running

   }
  }
  break;

 }

 return FALSE;

}

ansi/iso C++ compiler

Hi,

I learn that Visual C++ 6.0 is not ansi/iso compatible but Visual studio .net is. Can anybody elaborate a little more on it? Why one is not and the other is?

It is a matter of design from Microsoft. Visual C++ .NET is simply newer and is a better C++ compiler than its predecessors.

No compiler is actually 100% ansi/iso compatible. Ultimately VC++ 6.0 suffered from Microsoft wanting to ensure backward compatibility and that the standard was still not finalized. In the end, Microsoft responded to customer demand for fuller compatiblity. Now if we could just get them to fix all the goofiness with Visual Studio....

compilie error: error C2955: 'modulus' : use of class template requires template argument list

Hi there...
I'm using VC6 & STL in my program along with Openssl.
I'm getting compilation error in OpenSSL\bn.h

The error is as follows:-
error C2955: 'modulus' : use of class template requires template argument list
c:\program files\microsoft visual studio\vc98\include\functional(57) : see declaration of 'modulus'

There seems to be some kind of conflict in template names, because STL and OpenSSL structure are using same template name.
Is there any simple workaround for this ?

Any help is appreciated.
Sheetal.

Have you defined 'using namespace std;' ?
In that case, try deleting that and use the fully qualified name instead, eg. std::cout instead of cout.

Anyway, that's just a SWAG, because I rarely write C++ myself Smile | :)

CRectTracker+CScrollView="going crazy!!!"

Hi,

Did anybody put a CRectTracker on a CScrollView wider than client area (4000x4000 pixels for example) and do some scrolling and/or zoming? The MSDN doesn't help me at all! From my point of view the MSDN creators should explain very clear where the actual Draw-ing is made when CRectTracker::Draw function is called. It is made on client area - visible area(ex: 100x100 pixels wide) or view area (ex: 4000x4000 pixels wide)?

Why 6 is affraid of 7?
Because 7 8 9

Template instance names in the STL, when fully expanded by the compiler, often result in truly awe-inspiring identifiers that exceed the 255-character limit for identifiers in the debug info. Remember that many STL templates take a number of optional extra template parameters that specify such things as allocators, sorting rules, and hash traits. The compiler fills in these parameters with default values when generating the instance.

I've found this warning to be generally harmless. You can selectively disable it with:
#pragma warning(disable:4786)

RegisterHotKey function

Help!
I use RegisterHotKey function to define a global hotkey as following, I works with debug build, but crash with release build when the second I press the hotkey.
Could anyone help? Thanks!

CMainFrame::CMainFrame()
{
m_nHotKeyID = 100;

BOOL m_isKeyRegistered = RegisterHotKey(GetSafeHwnd(), m_nHotKeyID,
MOD_ALT, VK_TAB);

ASSERT(m_isKeyRegistered != FALSE);
}

//lets remove the hotkey block when the application is destroyed
CMainFrame::~CMainFrame()
{
BOOL m_iskeyUnregistered = UnregisterHotKey(GetSafeHwnd(), m_nHotKeyID);
ASSERT(m_isKeyUnregistered != FALSE);
}

Interesting.

Try calling it in OnCreate(). Make sure GetSafeHwnd() returns a valid handle.

Thanks, Kuphryn.
Actually I did call it in OnCreate, but also crash with Release build.
The point is it always work with Debug Build, but crash the second I press the hotkey with with Release build.
Do you have any Idea?

My application tries to print out in MM_HIENGLISH mode, however, the output on page is always offset a little. I have to call CDC::SetWindowOrg() inside CMyView::OnPrint() to balance out the offset. The funny thing is for different printer the offset is different. Can anyone help me out on the issue? I am using VC++ 5.0 Professional in Windows XP platform. Confused | :confused:

OpenFile > Cancel - Problem

TiberiusvP2-Feb-04 14:32

Hi there!
I have a problem with my MDI-application.
When the application starts, i want to have an OpenFile dialog. I have

cmdInfo.m_nShellCommand = CCommandLineInfo::FileOpen;

in CMyappApp::InitInstance() and

DoPromptFileNames(filename, AFX_IDS_OPENFILE,OFN_HIDEREADONLY | OFN_FILEMUSTEXIST , TRUE, NULL)))

in CMyappDoc::OnOpenDocument(), everything works fine, the dialog opens on startup.

Now the problem: by pressing the 'Cancel'-button, one would expect nothing to happen, no view to open, just the dialog to disappear.
But the view opens just like it would if one selected a file, and produces lots of trouble cause it actually has no file to handle.

I tried to work around this by closing it right away by calling CWnd::DestroyWindow() in my view's OnInitialUpdate() if there's no file to handle, but then I get in trouble with my CDoc*...

What I want is just a simple solution for this: Open a fileOpen-dialog, just close it by pressing 'Cancel' and closing it and launching my view by selecting a file...

I hope it is understandable, my english isn't actually the best Smile | :)

thank you and greetz

You should just need to return FALSE from your OnOpenDocument() function to cause MFC to not create an empty document/view.

I already tried that and it destroyed my MainFrame...
dunno how to fix it, so I do not open an openFile dialog on startup, would have been nice, but is not necessary.

Best regards
