Hi I have an application in which i am using the SHChangeNotifyRegister API to get the file system events. If I perfome file operations in the network path I am not getting any notifications. Can anyone help me in this regard.

Thanks in advance

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 have created one Combo box and one List Box in the dialogbox in Visual Studio.

I am working in Visual C++.NET framework.

now I want to access these controls in to the file, then how do I get the control over them? means objects?

and in the list box I have a browse button also, on clicking that button the folders (As in windows) shoulds be opened. Can anyone sent the code for that?

Thank you

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

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.
