you can use HTML Help Workshop (which you can download from Microsoft web site) to create the in-fashion *.chm help file. Then in your code, you can just use ::HtmlHelp(this->m_hWnd, helpname, 0, HH_DISPLAY_TOPIC); to display your help.

remember to link with htmlhelp.lib, and include <htmlhelp.h> in file "StdAfx.h".

Build does not work

TheoE31-Jul-02 7:03

31-Jul-02 7:03

I work with VStudio 6.0 Student edition. SP5

Well, it is not a problem to compile a hello application,
either command line or from the ide. It even is not a
problem to compile reversi, a c source.

But when i try to build flip3d or scribble, the build
either reacts by:

system beep

folowing messages:
--------------------Konfiguration: flip3d - Win32 Debug----
----------------
Microsoft (R) Program Maintenance-Dienstprogramm: Version
6.00.8168.0
Copyright (C) Microsoft Corp 1988-1998. Alle Rechte
vorbehalten.

or for scribble with a system beep and

the following messages:

Temporäre Dateien und Ausgabedateien für "Scribble - Win32
Debug" werden gelöscht.

--------------------Konfiguration: Scribble - Win32 Debug--
------------------
Building help file...

after these messages MSDEV still works with six threads.

What is my problem?

Lack of memory? I have got 512 Mb DDRam and a SIS 735 1,4
Ghz Athlon system.

Some ressources missing?

I have got nothing spectacular on my system.

By the way i have got an old Toshiba Laptop 150Mhz Pentium
system with 32 MB, i have got the same problem for scribble
there.

a further case on my desktop system:

After downloading a huge project from the internet i have
encountered the same problems with building the project.
After adjusting include paths the system compiles
all the source files. Then the system comes to the
point to build the dependencies.

And there it hangs up. Again, six threads are working.
And i can just stop MSDEV by either killing the process or
using ctrl alt del.

So whats the problem, how can i detect it and how can i
solve it?

while (!pRecordset->GetadoEOF ()).......no MSDN help on this?

ns31-Jul-02 6:59

31-Jul-02 6:59

I tried F1 for MSDN help on

GetadoEOF () for a recordset and there were no entries. I looked at msado15.tli and found:

inline VARIANT_BOOL Recordset15::GetadoEOF ( ) {
    VARIANT_BOOL _result;
    HRESULT _hr = get_adoEOF(&_result);
    if (FAILED(_hr)) _com_issue_errorex(_hr, this, __uuidof(this));
    return _result;

but cant decipher what this is doing? Its end of some file but which file? The web didnt offer any insight either though its used a lot. How does one figure out what these things are. Recommend a good basic , friendly ADO book?

Is this ADO stuff MFC or is it generic and we just happen to use it in an MFC project?
Thanks,
ns

Ask about how to use startdoc(), startpage() to print data on paper imediately.

ooosawaddee331-Jul-02 6:54

31-Jul-02 6:54

I want to ask about how to use startdoc(), startpage() to print data on paper imediately then receive the next data and print imediately and receive the next data and print ......

Example : If I want to print this below data in first page imediately and after that I receive the other data and print imediately not like Microsoft word which must receive all data and print 1 time.

110011110

How to do that loop?

This below is my program want to do that.

If first data is 110011110

I change 1 in the above data to solid black (which have 2 pixel width and 4 pixel height) and 0 in the above data to solid white (which have 2 pixel width and 4 pixel height)

code:
------------------------------------------------------------

DOCINFO di ;
CPrintInfo printInfo ;
CString filename ;
CDC dc ;
CRect draw_area ;
CPrintDialog dlg(FALSE) ;

if (Dlg.DoModal() == IDCANCEL)
return ;

HDC hDC = dlg.GetPrinterDC() ;
if (hDC == NULL)
return ;

di.cbSize = sizeof(DOCINFO) ;
di.lpszDocName = "Document name"
di.lpszOutput = NULL ;

// prepare the print information structure
dc.Attach(hDC) ;
printInfo.m_bDirect = TRUE ;
printInfo.m_rectDraw.left = 0 ;
printInfo.m_rectDraw.right = dc.GetDeviceCaps(HORZRES) ;
printInfo.m_rectDraw.top = 0 ;
printInfo.m_rectDraw.bottom = dc.GetDeviceCaps(VERTRES) ;
draw_area = printInfo.m_rectDraw ;

dc.StartDoc(&di) ;

//receive first data
CString testline = "110011110" ;

int x = 0 ;
int y = 0 ;
int pos = 0 ;
// start printing the document

dc.StartPage() ;

CBrush brush;

// Creation of the brush with a black color

brush.CreateSolidBrush(RGB(0, 0, 0));

while (pos < testline.GetLength())
{
if ((testline.GetAt(pos)) == '1')
{

// Create a rectangle with coordinates x,y,x+2,y+4 corresponding with top, left, bottom, right
CRect Rectangle(x, y, x + 2, y + 4) ;

// Fill a rectangle in the current device context or DC
dc.FillRect(&Rectangle , &brush);

x += 2;
}

else if ((testline.GetAt(pos)) == '0'){

x += 2;
}
pos++ ;
}
y += 4 ;
x = 0 ;
pos = 0 ;

dc.EndPage() ;
printInfo.m_rectDraw = draw_area ;

//OnEndPrinting(&dc, &printInfo);
dc.EndDoc() ;
VERIFY(dc.DeleteDC()) ;

Thank you

CTabCtrl: Remove from propertysheet

DroogsAlex31-Jul-02 6:51

DroogsAlex

31-Jul-02 6:51

I'd like to remove the CTabCtrl from a property sheet. Currently, I make it not visible, but I need to determine the size of the CTabCtrl in the property sheet to adjust the property pages accordingly. Otherwise, there's ugly space around it.

FYI: I'm using this approach as I use the property pages in a normal property sheet at times in addition to a "netscape'ish" property sheet.

Re: CTabCtrl: Remove from propertysheet

Joaquín M López Muñoz31-Jul-02 7:07

If you already have a pointer to the tab control (possibly with GetTabControl), GetWindowRect should return its dimensions. Then you can displace the remaining controls upwards in the OnInitDialog of the sheet just like this:

CWnd *pWnd=GetWindow(GW_CHILD);

while(pWnd!=NULL){
    CRect rect;
    pWnd->GetWindowRect(rect);
    rect.OffsetRect(0,-tabHeight); //tabHeight has been previously obtained
    ScreenToClient(rect);
    pWnd->MoveWindow(rect,FALSE);
    pWnd=pWnd->GetNextWindow();
}

Hi,

I've been staring at this problem for hours and hours... what is wrong?!
This is what I do:

...snip...

CComModule _Module;

BEGIN_OBJECT_MAP(ObjectMap)
OBJECT_ENTRY(CLSID_Lex, CLex)
END_OBJECT_MAP()

/////////////////////////////////////////////////////////////////////////////
// DLL Entry Point

extern "C"
BOOL WINAPI DllMain(HINSTANCE hInstance, DWORD dwReason, LPVOID /*lpReserved*/)
{
    if (dwReason == DLL_PROCESS_ATTACH)
    {
	TCHAR pszLoader[MAX_PATH];
	GetModuleFileName(NULL, pszLoader, MAX_PATH);
	_tcslwr(pszLoader);
	if (_tcsstr(pszLoader, _T("explorer.exe")))
	    return FALSE;

        _Module.Init(ObjectMap, hInstance, &LIBID_LEXBHOLib);
        DisableThreadLibraryCalls(hInstance);
    }
    else if (dwReason == DLL_PROCESS_DETACH)
        _Module.Term();
    return TRUE;    // ok
}

...snap...

I get this error:

---Configuration: LexBHO - Win32 Unicode Release MinDependency--------
Linking...
   Creating library ReleaseUMinDependency/LexBHO.lib and object ReleaseUMinDependency/LexBHO.exp
LIBCMT.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
ReleaseUMinDependency/LexBHO.dll : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

LexBHO.dll - 2 error(s), 0 warning(s)

But when I comment these lines out...

/*
	TCHAR pszLoader[MAX_PATH];
	GetModuleFileName(NULL, pszLoader, MAX_PATH);
	_tcslwr(pszLoader);
	if (_tcsstr(pszLoader, _T("explorer.exe")))
	    return FALSE;
*/

...things are working just fine. What is wrong with _tcslwr? Because that's where the problems start...

Help is much appreciated,

/Tommy

Joaquín M López Muñoz31-Jul-02 6:47

Ummm... the configuration you have selected (MinDependency) does not link the C run-time library to save space on the final DLL. So, you cannot use any of the functions provided by this library (like vg. _tcslwr). Either change the configuration or avoid calls to the C run-time library.

(Another shot in the dark) Seems like LIBCRT thinks is being linked against a console program instead of a DLL. Check the /subsystem directive in the linker part of the project settings.

Under your project settings, make sure that you have chosen one of the "Using MFC" options.

(IE. "Using MFC in a shared .dll" or "Using MFC in a statically linked .dll")

No, it works with a project I have and there's no MFC at all. And there shouldn't be!

It must be something else!

I had the same problem :
- put an empty main funxion somewhere to keep the linker happy
- don't use LIBC funxions
- tell me if you find another solution

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