Yes, it will make it smaller but you can shrink it down to the title bar size only which is what you want, right? I think you need to set CS_OWNERDRAW and draw the title bar yourself if you want buttons. Search this site and others for examples.

In winamp when the title bar is changing it is pulling bitmaps from either the default skin or from zip files containing the other skins (if you rename a skin file to .zip it will be unzippable). Same goes for the buttons and the rest of the graphics in winamp. I'm not sure what is done programatically to get them to draw over, but a few of the things mentioned looked like it could work.
I had a little fun doing a skin for winamp once so I learned about how they change the image. Smile | :)

I hope that helps some.

Hi,
what is the best (and simpliest) way to communicate between processes ? One process is typical MFC application, the second is console service. So how can these two applications communicate ? It must run under W95/98/NT/2k/XP.
Thanks in advance. Standa.

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,

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()) ;

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.

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();
}
