Yes the dlg window is created when clicking the pop up menu. I have no problem with cleaning up the pop menu as it is a local variable, see the code below:
{
..........
CMenu zooMenu;
zooMenu.LoadMenu( IDR_MENU1 );
CMenu* pPopup = zooMenu.GetSubMenu( 0 );
pPopup->TrackPopupMenu( TPM_LEFTALIGN|TPM_RIGHTBUTTON,
point.x,
point.y,
this );
}
It must be because something else. any other idea?

one of the buzz about com components is that they allow location independence; to include com comp "import" key word is used along with name and path so where is location independence?

That is only one way of importing a COM definition.
You can also use the progid or libid:
<br />
#import "libid:0B482F67-46DD-4b1a-BD7C-204444F452E0" named_guids<br />
#import "progid:SomeCOMLibrary.MyCOM.1" named_guids<br />
Using the import directive in this way will ensure path independence from your client program.

Hello,
I need to print files using MS Word automation and MFC. I use the PrintOut method available in the application object and it prints perfectly fine. But i'm not finding any method of printing files to a particular tray of the printer.
Code for the same is attached
******************************************************************************
Word::_ApplicationPtr m_pWord;
Word::_DocumentPtr m_pDoc;
/* ms-word print api */
m_pWord->ActiveDocument->PrintOut(covFalse, // Background.
covOptional, COleVariant((long)4), // Range.
covOptional, // OutputFileName.
covOptional, // From.
covOptional, // To.
covOptional, // Item.
COleVariant((long)1), // Copies.
COleVariant(PageRange ,VT_BSTR), // Pages.
covOptional, // PageType.
covOptional, // PrintToFile.
covOptional, // Collate.
covOptional, // ActivePrinterMacGX.
covOptional, // ManualDuplexPrint.
covOptional, // PrintZoomColumn New with Word 2002
covOptional, // PrintZoomRow ditto
covOptional, // PrintZoomPaperWidth ditto
covOptional
);
******************************************************************************
For tray selection am using the following methods, but the desired results are not being achieved. The mentioned method is placed before PrintOut function is called.
******************************************************************************
m_pWord->Options->DefaultTrayID = Word::wdPrinterLowerBin;
******************************************************************************
Thanks for any help provided

Hi All,
My application has strings hard-coded in code. To Provide multi-language support in my application, i need to make these strings as a part of resource in the project.
If anybody knows any tool that will move these hard-coded strings to the Resource and write the code at those places to load them from the resource whenever needed, please tell me where to get tool or if u have it, send me at abhijeet23@gmail.com
Thanks in Advance..

I don't know of a tool to extract the string ( and put them in a text file ) , and replace them with SIGNIFICANT ids; you'd better take a few hours doing it manually.
as for the second part, you need to create a resource DLL ( see here [^] ) and load the DLL depending on the current user language.
and in your code, use CString::LoadString( UINT id ); to load the string from the resources.

Hi,
When you disable the titlebar (and thus the minimize-button) in a dialog, the application wont minimize anymore on a taskbar click.
I was wondering if you can recreate that behaviour, so that the application minimizes even without a titlebar.
I tried already using an own WndProc-Method to catch the messages of the taskbar to look for a WM_LBUTTONUP or DOWN to minimize and restore the application myself, but the GWL_WNDPROC of SetWindowLong seems to only work for windows of the own process, so that didnt work...
Has anybody got an idea or maybe done that himself already?
thanks alot!

I hope this is what you're looking for. I've used ShowWindow(SW_MINIMIZE) to minimize my application. (Alternatively, ShowWindow(SW_MAXIMIZE)) Or you might want to check out CWnd::SetWindowPlacement().
Hope this helps!

Hi Danny,
This is the way to minimize the window, but my problem remains... I need to know when to call ShowWindow(SW_MINIMIZE) and RESTORE, so when someone clicks on the button in the taskbar i need a way to catch that clicking.
Minimizing my application itself isn't the problem, but getting it on that taskbar click is 
thanks for answering though!

Ah, I see. Sorry, I don't know about what you're looking for. Are you working with an SDI, MDI, or Dialog app? If a dialog, are you opposed to putting your own minimize button on the dialog. If SDI or MDI, can you put an entry in a menu or toolbar? Admittedly, this isn't as good of a solution as being able to do the common taskbar click, but as far as handling WM_LBUTTONDOWN messages, I think that only works within your own app, unless you don't release the mouse if it's clicked outside your app I suppose, (by overriding the WM_CAPTURECHANGE message?)
Or... why do you want the title bar gone? Just so the user can't move the window around? You can remove the user's ability to do this.

It's a Dialog and the reason for not having a normal titlebar with minimize-button (and thus the normal taskbar behaviour) is, that my boss wants a customized titlebar.
The Dialog has a button for minimizing and that works as planned, but it would be nice if the application would still behave like any other dialog does (so minimize when clicking on the button in the taskbar).
I can get a handle to the taskbar itself, but i dont know how to be able to hook on its messaging system to be able to react to those WM_... mouseactions myself.
i got the idea with SetWindowLong from this article: http://www.pocketpcdn.com/articles/close_app.html , but for GWL_WNDPROC under NT/2k/XP MSDN says: "You cannot change this attribute if the window does not belong to the same process as the calling thread."

Hi there!
I'm devolping an communication program, and sometimes I need to do some sleep's. The problem is that I use some external components that use the PostMessage API, and while the app is sleeping, the messages aren't dispatched..
I've developed a funcion with the folowing code:
void DispatchMsg()<br />
{<br />
MSG msg;<br />
DWORD dwi=GetTickCount();<br />
while (::PeekMessage(&msg, NULL, NULL, NULL, PM_NOREMOVE))<br />
{<br />
::TranslateMessage(&msg);<br />
::DispatchMessage(&msg);<br />
if ((GetTickCount()-dwi)>2000)
break;<br />
}<br />
}
But it seems that some time I get some repeated messages... I've also tried replacing the PM_NOREMOVE by PM_REMOVE parameter in the PeekMessage, but some times the app seems to hang...
Do you have any ideias?
Thanks all for your time.

 How should I use it? Create a foo mutex or event?
I have a main wnd for the app, and a second wnd to receive messages from the comunication component.
I need to call the component api, wait some time so it can send messages to my wnd, and then process them...

Do you want to freeze the window for a while, waiting for the api to throw a message to the queue?

That can be an option!
How do I use the API you've mentioned?

No, sorry. I was thinking about your component's API
I don't know what your code is about but if you need to freeze the window - or just a part of it - then you might filter all the messages except those coming from the component and a timer which, when appropriate, signals the timeout as the moment of unblocking. If no freezing is required then you should do nothing, just pump the messages as usual.
Something like this...

Hello,
Since you use PM_NOREMOVE, the same message gets dispatched as long as 2 ms. You should remove the message for this purpose.
Since you do some communication, may I suggest that you do that in a seperate thread. This doesn't interfere with the GUI and enables you to program more flexible. This also saves you the DispatchMsg() function.

It's not a very easy thing to do... I already have to many threads, and some more windows.
The idea is to give the component some time to post to my wnd the results...
Do you know why the PM_REMOVE sometimes hangs the application?
|

Hello,
Removing the message using PeekMessage probably doesn't hang your application. Your problem probably is that DispatchMsg() doesn't wait if there is no message available. That function should look like this:
void DispatchMsg()
{
MSG msg;
DWORD dwi=GetTickCount();
while ((GetTickCount()-dwi)<2000)
{
if (::PeekMessage(&msg, NULL, NULL, NULL, PM_REMOVE))
{
::TranslateMessage(&msg);
::DispatchMessage(&msg);
}
else
{
::WaitForSingleObject(::GetCurrentThread(), 50);
}
}
}
