a problem about "OnLButtonDblClk "

In my program, I create a controlbar . If I double click on the controlbar, it can get the LButtonDblClk message. Then I create an rebar on that controlbar, but if I double click on the rebar, the controlbar can't get the LButtonDblClk message. And I find if I right click on the rebar, the controlbar still can get the right-click message. It is strange.How could I get the LButtonDblClk message in the controlbar when I doubld click on the rebar?

Thanks
Benben

are you sure it is the right control that is handling the message ? (be sure it is the child class tha is doing so)

Yes，I don't think it is a right control.
But what I mean is I want to do something when the user double click on the controlbar( include the area covered by the rebar), how should I do?(And I am sure the rebar needn't process this message).And it really work for right click message.

Thanks

You'll need a grid.

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.

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.

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.

dvdplayer class and player class

26-May-04 21:45

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

VS.Net --> VS.Net 2003: My working ISAPI Extension is now broken.

Hi all,

I'm writing my first ISAPI Extension. I'm not very familiar with anything webby, but everything has been going 'OK' Hmmm | :|

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. Suspicious | :suss:

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... Confused | :confused:

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
