Use MDI, multiple views per document too. You might want to take a good look at Chris' excellent grid control (I've used it in similar applications), as it should help with most of the 'spreadsheet' style stuff.

HI.
Steps to add a BMP as a resource.
and how to load it.
if Picture COntrol is used then steps
plz
thanx
|
|
|
|
|
Go to resources tab
right click on topmost tree item 'resources' / choose insert... / choose bitmap and click 'import ...', choose bitmap you want to import.
When you want to place it into some dialog then: Insert Picture Control (2nd icon from left), double click the control (you can see black rectangle on dialog) to see its properties.
Change type to bitmap; change image to your imported bitmap's name as displayed in 'Resources\Bitmap'
Thats it ... now the black rectangle should change to your bitmap.

|
|
i did all step u said .. but ther is only a white squre appear.
nothing else
|
|
|
|
|
Is there only a white square also when you run the program ? Because sometimes white square shows only in dialog design. Else then that you should try to change BMP's colour bit depth in some graphic editor, that should solve problem.

hello, I wrote a player class and I also wrote a dvdplayer class that is supposed to inherit from player class(both are very simple, no GUI, just simulateion)
my question:
1. in dvdplayer what should I put as the type of disk tray and media reader, should I create a new class?
//dvdplayer.h
#ifndef DVDPLAYER_H
#define DVDPLAYER_H
#include "player.h"
#include <iostream.h>
#include "mystring.h"
#include "button.h"
#include "terminal.h"
class dvdplayer:public player
{
public:
dvdplayer(const char * info);
~dvdplayer();
virtual int play();
virtual int stop();
virtual int powerOn();
virtual int powerOff();
int videoConnect();
int audioConnect();
void insert();
void remove();
private:
terminal vedio_out;
terminal audio_out;
//disk_tray;
//media_reader;
};
#endif
2. Can somebody give me some suggestion on both player and dvdplayer class? I am a student who just start to learn C++, Thanks for your help!
//player.h
#ifndef PLAYER_H
#define PLAYER_H
#include "mystring.h"
#include "terminal.h"
#include "button.h"
class player
{
public:
Player(const char * info);
virtual ~player();
void getPlayerInfo();
//enum status {Playing, Paused, Stopped, Ejected, Open, Close, connected, disconnected);
void acConnect();
void setPlayerInfo();
//void acConnect();
void acDisconnect();
virtual int play() = 0;
virtual int stop() = 0;
virtual int powerOn() = 0;
virtual int powerOff() = 0;
protected:
button player;
button stop;
button power;
mystring PlayerInfo();
terminal AC;
};
#endif
_____________________________________
#include "player.h"
player::player(const char* info)
{
setPlayerInfo(info);
AC.setState(0); //set 0 to terminal ac denotes disconnect;
}
//constructor;
player::~player()
{
delete playerInfo;
delete polayer;
delete power;
delete stop;
delete AC;
}
//destructor;
void player::acConnect();
{
if(AC.getState == 0)
AC.setState(1);
else
cout<<"AC has already connected"<

Hi all,
I'm writing my first ISAPI Extension. I'm not very familiar with anything webby, but everything has been going 'OK'  so far (I haven't had to pull my hair out for more than about a day at a time before figuring stuff out).
Anyways... in order to debug my ISAPI Extension I followed the instructions found under this heading:
Establishing Windows NT Security Privileges and Debugging an IIS 4.0 DLL
at this website:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vsdebug/html/vxtskdebuggingwithiis40orlater.asp
Dodgy as all hell, but it worked, so I'm not complaining. 
As I said, everything was going well. I'd browse to right URL, see a nice web page, click some buttons, get another webpage... all good... until I moved from VS.NET 2002 to VS.NET 2003.
Now... when I browse to where my extension is (and where it has always been), I don't even get into my DLL (not even to the constructor of my extension class). I get this error instead:
"First-chance exception at 0x77f966bc in Inetinfo.exe: 0xC0000139: Entry Point Not Found."
and the resulting web page tells me this:
"The specified procedure could not be found."
I'm not exactly sure where to start with this... 
The only thing I can see that has changed is that when InetInfo.exe starts (when I run the debugger), it loads these:
C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\aspnet_filter.dll
C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\msvcr71.dll
and I'm assuming it would have previously loaded them from
C:\WINDOWS\Microsoft.NET\Framework\v1.0.3705
My box:
Windows XP Pro sp1
IIS 5.1
Visual Studio .NET (2002)
Visual Studio .NET 2003
IE 6 sp2
Mez is not pez.

POINT ptOffset;
RECT rcItem;

I'm trying to read from a socket using this code:
while (e = recv (m_socServer, m_szBuff, sbuff, 0)) The code works fine the first time it's executed, but then hangs the next time it gets to it. Any insight into why this is happening would be appreciated. Thanks.

Sounds like there is no data for it to receive. recv will hang if there is no data available.

your socket is a blocking socket
and is waiting for data to arrive before that code will continue
if you want it to return if there is no data to return try using a non blocking socket

You could check that the socket is readible firstly
BOOL IsSocketReadible(SOCKET socket, DWORD dwTimeout, BOOL& bReadible)
{
timeval timeout;
timeout.tv_sec = dwTimeout / 1000;
timeout.tv_usec = (dwTimeout % 1000) * 1000;
fd_set fds;
FD_ZERO(&fds);
FD_SET(socket, &fds);
int nStatus = select(0, &fds, NULL, NULL, &timeout);
if (nStatus == SOCKET_ERROR)
return FALSE;
else
{
bReadible = !(nStatus == 0);
return TRUE;
}
}
You specify a timeout for it to wait for data on the socket.
NOTE: Param 1 is ignored in windows sockets.

Thanks for that code.
This is sort of unrelated to the previous question, but still about sockets...will program execution speed affect whether a socket can be read or not, for example if I send data and then try to receive on the next program line will the program most likely hit that line before the server has had time to respond?
Also would you happen to know how to connect to a POP3 server using windows sockets? I'm trying to do that but after I send the first send/recv (after connecting) the server doesn't seem to respond anymore...I even blocked on select for 20 seconds, but there was still no response from the server. Thanks for the help.

Absolutely, program execution is vastly faster than network communication. You will definately have to wait if you attempt send on one line then receive on the next.
If you are not bothered about when the data is received you can even spawn a thread to do the reciept. In fact this is not uncommon. When the thread gets the data it can post a thread message to the main application to go and do something with it.
WRT POP3 here is a great article http://www.naughter.com/pop3.html[^]

BUILD AN MFC MDI WITH 2 FORMVIEWS THAT I CAN DISPLAY BY SELECTING IN A PULL DOWN MENU.
THE PROBLEM STARTS WHEN I CHOSE THE NEW WINDOW MENU.
I CAN STILL USE THE PULL DOWN MENU TO VIEW ONE OF THE 2 FORMVIEWS ON THE NEW WINDOW, BUT WHEN SELECT THE ORIGINAL VIEW AND USE THE PULL DOWN MENU TO SWITH TO THE OTHER FORMVIW, I GET AN ASSERTION ERROR. THE ERROR HAPPENS IN THE BASE CLASS'S SetActiveWindow() and the error pointing arrow points to IsChild(Wnd* pView).
HERE IS THE RELEVANT CODE:
*******************************
BOOL CChildFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
/**********************************/
CMainFrame *pParentFrameWnd;
pParentFrameWnd = (CMainFrame*)this->GetParentFrame();
// pParentFrameWnd = (CMainFrame*)pApp->m_pMainWnd;
/*********************************/
CMDIPointApp* pApp = (CMDIPointApp*)AfxGetApp();
//ASSERT_KINDOF(CMDIPointApp, pApp);
CView* View;
CMDIDocTemplate* pTemplate;
POSITION pos = pApp->GetFirstDocTemplatePosition();
while(pos)
{
MessageBox(str,"CChildFrame::OnCreateClient()",MB_OK);
pTemplate = (CMDIDocTemplate*)pApp->GetNextDocTemplate(pos);
pContext->m_pNewViewClass = pTemplate->GetViewClass();
View = (CView*)CreateView(pContext);
ASSERT(View != NULL);
pTemplate->pView = View;
View->SetDlgCtrlID(0);
}
// ANY AND ALL CRICHEDITVIEW'S IN THE APP MUST BE FIRST VIEW(S) TO BE ACTIVATED
//IN ORDER FOR LAYOUT TO WORK. I ONLY HAVE ONE CRICHEDITVIEW IN MY APP
pTemplate = pApp->GetTemplate(RUNTIME_CLASS(CRICHEDITVIEW1));
if(pTemplate)
SetActiveView(pTemplate->pView);
pTemplate = pApp->GetFirstTemplate();
ActivateView(pTemplate->GetViewClass());
//DO NOT CALL CMDIChildWind::OnCreateClient since you are overriding behavior here
//return CMDIChildWnd::OnCreateClient(lpcs, pContext); //otherwise layout does not work
return TRUE;
}
void CChildFrame::ActivateView(CRuntimeClass *pViewClass)
{
CMDIPointApp* pApp = (CMDIPointApp*)AfxGetApp();
//ASSERT_KINDOF(CMDIPointApp, pApp);
CView *pActiveView = GetActiveView();
CRuntimeClass *pRun = pActiveView->GetRuntimeClass();
CMDIDocTemplate *pNewTemplate = pApp->GetTemplate(pViewClass);
CMDIDocTemplate *pActiveTemplate = pApp->GetTemplate(pRun);
//CMDIDocTemplate *pActiveTemplate = pApp->GetTemplate(pActiveView);
if(pNewTemplate == NULL) return;
if(pNewTemplate == pActiveTemplate)
{
MessageBox("NewTemplate == ActiveTemplate","");
return;
}
pActiveTemplate->pView->SetDlgCtrlID(0);
pNewTemplate->pView->SetDlgCtrlID(AFX_IDW_PANE_FIRST);
pActiveTemplate->pView->ShowWindow(SW_HIDE);

return (pActiveView->GetRuntimeClass() == pViewClass);
return FALSE;
}
