I've never seen such a message. Does it come from within MFC?

yes it comes from MFC when we compile our application with property page's size greater than specified sizes

Then it should be easy enough to track down and see what conditions are causing it to be displayed.

I don't understand the problem. How does the filename box being a combobox instead of an edit control change things?

microsoft compound document nested

Hi,
I am working on writing a MFC application supporting both container and server of compound document. After I inserted my object into Microsoft word, I also inserted another compound server object(for example Microsoft equation 3.0) into my object. But, after i edited a equation and got back to word, if i want to edit the equation object again, the equation was gone. And the system pop up a message box which say "unable to update client".

However, if I inserted my oject into Microsoft Excel/Power Point and do the same thing as above, everything is ok.

Why a nested compound document work well in Microsoft excel/power point but not Microsoft word?

Moreover, if i insert a Microsoft wordpad object into Microsoft word, and then insert a microsoft panint object into this Microsoft wordpad object, there are the same error like my compound document object.

Does anyone can help me in this regard?

i have a question ??
how do u specify the directory path in SHChangeNotifyRegister ??

i mean,
if i have 3 drives, C: D: and E:
how do i receive notification only from D: ???

Try using FindFirstChangeNotification / FindNextChangeNotification / FindCloseChangeNotification
set of API's.

try specifying the network path.

i am not sure whether this will work, but just give it a shot.

Thanks . obviously you cannot give the network path in the APi. I gave CSIDL_DRIVES i am getting notifications from all the local drives. but if i connect to a network system and perform file operations I am not getting the notification.

i did not get the first part of ur question.
anyways, here is the code to display the open dialog box.

NOTE:
this is vc++ SDK (win32) code. i dont know whether u can use the same code in vc++.net
but i think there would only be minor differences.

OPENFILENAME opn;
TCHAR lpszFile[255];
TCHAR lpszFileTitle[255];
HWND hWndOwner; // handle of the owner window.
HINSTANCE hInst; // instance handle of the application.

opn.lStructSize = sizeof(opn);
opn.hwndOwner = hWndOwner;
opn.hInstance = hInst;
opn.lpstrFilter = "All Files (*.*) ";
opn.nFilterIndex = 0;
opn.lpstrTitle = "Open Dialog";
opn.Flags = OFN_EXPLORER;
opn.lpstrFile = lpszFile;
opn.nMaxFile = 255;
opn.lpstrFileTitle = lpszFileTitle;
opn.nMaxFileTitle = 255;
GetOpenFileName(&opn);

sorry for the earlier post. i did not read ur question properly...

deepgeorge13-Dec-05 21:34

13-Dec-05 21:34

oh sorry,
i did not go thru ur question properly..

use the ShellExecute/ShellExecuteEx

Eg:
ShellExecute(handle, NULL, <fully_qualified_path_to_folder>, NULL, NULL, SW_SHOWNORMAL);

or

ShellExecute(handle, "open", <fully_qualified_path_to_folder>, NULL, NULL, SW_SHOWNORMAL);

To explore a folder, use:

ShellExecute(handle, "explore", <fully_qualified_path_to_folder>, NULL, NULL, SW_SHOWNORMAL);

To launch the Shell's Find utility for a directory, use:

ShellExecute(handle, "find", <fully_qualified_path_to_folder>, NULL, NULL, 0);

for more info:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/shell/reference/functions/shellexecuteex.asp

i am not so sure if v can use "CreateProcess()" to open folders.
if yes, use CreateProcess().

how to access a resource in an .ocx. pls help

deepgeorge13-Dec-05 20:53

13-Dec-05 20:53

hi,

i need to access menu (resource) stored in a .ocx file which is loaded in my application.
the purpose is to disable (gray out) a menu item in the pop up menu.
the component which is pulled into my application, has a treeview in it.
when i right click a node in the tree view, it gives me a pop up menu.
now, my problem is: i want to disable one menu item in this popup menu.

i am subclassing the components (tree control) window proc.
i am able to handle messages such as WM_RBUTTONUP/WM_CONTEXTMENU, etc.
but, to disable the menu item i need the menu handle.
how do i get the menu handle ??
i tried using HMENU hMnu = GetMenu(hWnd);
and also did a HMENU hMnuParent = GetMenu(GetParent(hWnd)); where hWnd is the tree control handle.
but, i could not get the menu handle.
how do i get this.
do i need to use the FindResource/LoadResource/LockResource set of API's ???
but, i dont know the name of the resource (menu)
then, how do i use FindResource to locate the resource ??
can someone help ??

thanks.

Deep George Zachariah.

I am trying to use the function, PathFileExists to check if all dependency files are existing, so that if not i could quit my application informing the user about the missing module. But it worked for the first 3 compilations. Later, the linker gives me the following error.

error LNK2001: unresolved external symbol __imp__PathFileExistsA@4
fatal error LNK2001: 1 unresolved externals
Error executing link.exe

What exctly is the problem? How would I resolve this?

I think you changed your build configuration, so you need to put it again for the linker:
shlwapi.lib

this is this.
