i know the problem, but windows doesn't provide any API for getting this special information.
Don't try it, just do it!

Hi,
TAB Messages from child dialog is not going to child dialogs message queue,but it is to the parent windows!! So whenever TAB is pressed parent window gets the focus. How to get the control to the child dialog itself!
With Best Regards,

In MFC or Win32? If Win32 are the dialogs modeless or modal? If modeless, are you calling IsDialogMessage in your message loop?

Hi,
If I have two doc/views and I have some data in the second viewor document.
How do I get the data from the second view document if I am currently in the first view/document.
I must be doing the dynamic_cast wrong as it is non null but I can't access any local data from the class. Has any one got a small code fragment that explains how to get to another doc/view when inside a doc/view using the CDocTemplate stuff?
I used GetDocTemplate etc but now I would to get to the current view.
Thanks,
flip

Not sure if this is what you need to do.
In your document object use GetDocTemplate(). You can then iterate all the open documents of that type using GetFirstDocPosition() and GetNextDoc(). You can compare the returned pointer to this to see if you are looking at yourself. Once you have the pointer(s) to the other doc(s), you can iterate them for their view(s) using GetFirstViewPosition() and GetNextView()
If you are starting in the view, you need to use GetDocument() first of all.

Hello guys,
I am having this problem to access (more specifically, to change text) the statusbar directly or indirectly in a MFC worker thread of my dialogue-based application.
The status bar was firstly created in my main dialogue class' OnInitDialog().
m_statusbar.Create(this);
m_statusbar.SetIndicators(indicators, 2);
m_statusbar.GetStatusBarCtrl().SetBkColor(RGB(180,180,180));
m_statusbar.SetPaneText(0, "Offline");
SetTimer(100, 1000, NULL);
The m_statusbar is a CStatusBar type member in the class declaration.
CStatusBar m_statusbar;
As I need to change the text in some functions in other classes and threads, I tried to make the statusbar accessible globally by having
pStatusBar = &m_statusbar;
also in the OnInitDialog, where CStatusBar *pStatusBar is declared as a global variable.
While there was no problem with compilation, but I'd encounter assertion error if I try to use pStatusBar to change text of the statusbar in the thread function, whether directly or indirectly (uses the change statusbar text function in other class), examples below:
UINT doPrintingProc(LPVOID param)
{
COtherDlg *ptr = (COtherDlg *)param;
pStatusBar->SetPaneText(0, "Testing");
ptr->ChangeStatusText("Testing");
}
I use the similiar way to manipulate the globally accessible CListView and CEdit text box, all seem to have no problem.
Would appreciate if someone could point out where I have done wrong.

I suspect your CStatusBar is doing a sanaty check and your blowing up in a ASSERT_VALID(this) call somewhere in CStatusBar. One of the things MFC classes often do is check for themselvs in handle maps when you call various mathods on them - the long and short of it is not all MFC classes can be passed around between threads in this way, and there is nothing you can do about it directly.
what you have to do is to use messages to communicate between the threads.
Declare a custom message:
#define WM_CHANGESBTEXT WM_USER+0x400
Add a hander for it to your dialog:
class CMyDialog:
{
LRESULT OnChangeSBText(WPARAM, LPARAM);
.
.
.
};
Wire up the message map:
BEGIN_MESSAGE_MAP(CMyDialog...)
ON_MESSAGE(WM_CHANGESBTEXT, OnChangeSBText)
...
Then implment the method:
LRESULT CMyDialog::OnChangeSBText(WPARAM wp, LPARAM)
{
LPCTSTR pszText = (LPCTSTR)wp;
m_statusbar.SetPaneText(0, pszText );
ChangeStatusText(pszText);
return 0;
}
Then in the thread, rather than do it directly, just send a message to the main dialog
UINT doPrintingProc(LPVOID param)
{
LPCTSTR pszString = "Testing";
AfxGetMainWnd()->SendMessage(WM_CHANGESBTEXT, pszString);
}
Dont forget to use Send (not post) message if your string can go out of scope.
}

Thanks alot, Diddy,
it works out nicely except a small fix for me to get it compiled -
AfxGetMainWnd()->SendMessage(WM_CHANGESBTEXT, (WPARAM)pszString)
As you have pointed out, not all of MFC classes can be passed around among the threads. But for those they do work out no trouble (direct pointer passing), is it safe to do it that way and not changing to SendMessage? This brings my another question. From what I'm thinking of SendMessage() now, it allows one thread (or class etc..) to basically send command the other class to perform its specific function(s), with options to also pass some desired data along. In my case, the changing of statusbar's text is done by its belonging class (my main class) with the original statusbar member. Therefore, no confusing pointer is there. Is it correct?
Thanks again for the help
really appreciated

Arr well, when you write code without a compiler one error isn't bad i suppos 
As a general rule of thumb, it's only the classes that interact with Windows etc that will cause you problems (this isn't a golden rule by anymeans) and out of those window classes, it's the ones that are more than just a thin wrapper round the Win32 API that cause problems. For example, CEdit is just a very thin wrapper around a edit control, and works fine, as you found out CStatusBar is more than that - and gives you problems. Its usually the classes that do anything at all with handle maps that don't work - as these are always local to the thread, and since your control is subclassed (by means of a DDX_Control statment) in your main thread,it's handle resides in that threads handle map.
As for the ones that do work - yes, it is safe to use them, but - you have the usual thread issues to think about. MFC classes are thread safe at the class level, but not the object level - IE to different instaces of a the same class provide no problems, but sharing the same instance might. It really depends on your app. You may find you need to use critical sections or other thread sync primatives to protect your control across threads, but you may be able to do without. It's all about thinking about what each thread is doing to the control - usually if one thread is just updating some text in the control, and the other is showing that text, you can get away without them. Where as if both theads are say updating the control's text, you shoud use a critical section to ensure they don't access the control at the same time.

Thanks for the reply again, Diddy.
As you stated here that the classes that are always local to the thread don't work well, SendMessage() can be used to let one class to tell the other class (of the statusbar member) to perfrom some functions *locally*. And so it'd work. Whereas my original method was trying the directly access the member residing in one thread from another thread. I just want to make sure I've understood that what SendMessage() actually does A communicate link where different classes or threads will talk to each other and ask to perform some local functions.
Thanks,
Johnny

plz give me example on creating web server that can serve dynamic page. I've already succeded using CreateProcess on C++ to serve PHP page. But how can i serve ASP page? are there ASP on windows that can be treated like CGI? or I must use ISAPI filter 
If i must use ISAPI to serve ASP, plz give some advise or example!
THX A LOT, I REALLY NEED IT (for school task)

If you want to server ASP, you should install IIS, it comes free with Windows 2000, and XP Pro. But you should also ask your class to move into the 21st century, ASP is dead, and good thing too.

no no...you don't know what i meant. I want to create(write code) web server using c++. just like IIS, but it can run independently(on diff port). now i want my web server can accept ASP or PHP page like what IIS does.
yeah, my school is a little bit ....but, that's the homework. thx anyway.

Simple.
You use RegisterHotKey to register a new, global, system wide hotkey that can be used to send a predefined WM_HOTKEY message to the targetted window.
For example, this code piece creates a hotkey ALT+Z for the calling thread.
RegisterHotKey(NULL, 0x0010, MOD_ALT, VK_Z); Now, whenever you press ALT+Z, a WM_HOTKEY message is generated and posted into the calling thread's message queue. You can then create a message-map entry for MFC applications using
BEGIN_MESSAGE_MAP( CMyWindow )
ON_MESSAGE( WM_HOTKEY, HandleHotKeyPress )
END_MESSAGE_MAP See ON_COMMAND for information about the declaration of the handler function. It generally is a function taking two parameters of type WPARAM and LPARAM and returning a UINT or a boolean value. It might also return nothing.
You should store the hotkey identifier (0x0010) into a global variable, like a const UINT. This way you can call the UnregisterHotKey by using a constant instead of a raw number. Always remember to call the unregistration function when you no longer need the hotkey. Otherwise your application will fail to register a hotkey, because it's already reserved. Also, keeping the hotkey association active without having the target handler available may cause a system crash on Windows 95/98/Me.

Thanks, Antti.
I create an HandleHotKeyPress like this:
void CMainFrame::HandleHotKeyPress ()
{
MessageBox("aa");
}
It work with debug build, but crash when the second I press the hotkey with Release Build. What's the problem?

Hi,I'm looking for the way of getting information of Status of Object such as object creation,activation,deactivation etc..
I thought It would be possible to get that infomation Using CLSID of the Object.
But I couldn't find it at all.
Please Help me..
Any idea will be helpful.

You're obviously talking about COM+ ? Why not just create a log file in your class, and then write to it when those events are called, with a timestamp ?

I can't modify the Component.
I'd just like to monitor whether Objects are activated witout modifying components.
Please,Help me........

Check out the DevelopMentor site. I believe there is a generic "proxy" wrapper that provides COM interception. What it will do to performance is anyone's guess, and I imagine you might need to tailor it severely.

Hello,
I am in the process of implementing a serial interface in my existing Visual C++ project by using the CSerialWnd functions as described in great detail in Ramon de Klein's contributed source code:
http://www.codeproject.com/system/serial.asp
I am able to perform the CSerialWnd::Open function on the COM1 port, and then expect to receive window notifications back in my main windows notification handler routine. I'm not a veteran Windows programmer so I may not have all the terminology exactly right. The call that I use to set that up is as follows:
lLastError = serial.Open ("COM1", hdlg, WM_NULL, 0, 2048, 2048);
if (lLastError != ERROR_SUCCESS)
here(0,"Error opening serial port");
lLastError = serial.Setup(CSerial::EBaud38400,CSerial::EData8,CSerial::EParNone,CSerial::EStop1);
if (lLastError != ERROR_SUCCESS)
here(0,"Error opening serial port");
lLastError = serial.SetupHandshaking(CSerial::EHandshakeSoftware);
if (lLastError != ERROR_SUCCESS)
here(0,"Error opening serial port");
lLastError = serial.SetupReadTimeouts(CSerial::EReadTimeoutNonblocking);
if (lLastError != ERROR_SUCCESS)
here(0,"Error opening serial port");
I have run this code in debug and verify that I can indeed open the COM1 port. When I had another application using the port the code would detect the error. Passing in WM_NULL as the 3rd parameter in the Open should cause Windows to use the default notification message number of CSerialWnd::mg_nDefaultComMsg. When I looked through the include files I never found an exact definition of what this was. That was how I intended to determine which messages in my notification handler came from the serial interface thread that gets created by the Open. I decided to step through the code and came across this section where it gets assigned:
long lLastError = CSerialEx::Open(lpszDevice,dwInQueue,dwOutQueue);
if (lLastError != ERROR_SUCCESS)
return lLastError;
// Save the window handle, notification message and user message
m_hwndDest = hwndDest;
m_nComMsg = nComMsg?nComMsg:mg_nDefaultComMsg;
m_lParam = lParam;
// Start the listener thread
lLastError = StartListener();
When I looked at m_nComMsg it has a value of 49839 after it gets set. The problem is, when I look at all the messages coming into my notification handler I don't have any that are 49839. There are lots of messages coming in that I believe are the result of my sending a couple "hello world" messages into the Windows program. But they have message ID's of like 307,309,312.
I started trapping all messages coming into the notification window and time stamping them. Before and after sending the "hello world" serial data in, I hit a button twice that causes the 1006 LOWORD value of wParam. I did this to make it easy to see where exactly I should have been seeing the serial data notifications. Below is the diagnostic notification information. I will only include one of the preceding and trailing 1006 messages to keep it short:

dlg Msg 346 is 273 WM_COMMAND hiword wParam = 0 loword wParam = 1006 at time Feb 3, 2004 2:55:10 PM 426 ms
I pushed a button on the GUI that caused the 1006 notification at 2:54:40, the 2 serial strings were sent in at 2:54:50 and 2:55:00. The next 1006 button push was done at 2:55:10. As you can see, the 1006 notifications came in almost exactly when they should have. The data between that reflects the serial data do not appear at 2:54:50 and 2:55:00.
The main question that I have though, is why don't the serial interface notifications have a dialog message type of 49839 like I expect. Also, the different types of serial message notifications are supposed to come in as the LOWORD of wParam. This is an enumerated type defined in WinBase.h where received data is a 1, sent data complete is 4, break received is 64, etc. But the data that I am getting in wParam is nothing like these, even if you account for the fact that multiple bits might be set at the same time.
I did find another example of a similar implementation at this web page:
http://www.icculus.org/~lucasw/School%20Projects/478/PCinterface/ffconst.cpp
Any help would be greatly appreciated. As I mentioned I am not a Windows programmer. My background is real time single board computer embedded systems using vxWorks. The learning curve is pretty steep for the Visual C++ GUI code.

Just wanted to let you all know that I figured out the problem in case someone comes upon this thread in the future. The problem that I was having is that my declaration:
CSerialWnd serial;
Was located in the InitDialogProc routine which would get called from the main dialog processing routine upon receipt of the WM_INITDIALOG notification. I moved that declaration to be global and I started receiving serial notifications in the main dialog processing routine. Now I will be able to write the code that handles the serial data stream.
Good Luck,
Robert

Hi,
I am using Visula C++ 6.0. I want to print a document to a printer. But I want to print to using a specific paper tray of the printer. I can not user prinet dialog, as I want to add this code in a service application.
Thanks

You'll need to setup the DEVMODE struct to point to the paperbin that you want to use. See MSDN and search for DEVMODE.
onwards and upwards...
