Also, after OpenMutex(), the thread doesn't own the mutex so there's no need to release it.

Judy Subclassing and hooking the Microsoft Office 2000/2003/2007 File Open / Save Dialog boxes using Win32 C code JuggernautMsn4-Aug-07 2:23 JuggernautMsn 4-Aug-07 2:23  Hello everybody, I am in the middle of a project that involves hooking the file/open save and browse for folder dialog boxes of he currently installed windows applications and manipulate them by sending windows message codes. I am stuck with a problem in doing that. I have been able to hook into the file/open save dialog boxes and manipulate them , when the applications (Notepad,Wordpad,Adobe Acrobat etc.) uses the windows common control dialogs (i.e Common Dialog Box Library).The window class type of these type of dialogs is #32770(Dialog). But the microsoft office suite doesnot use this library to generate the file open / save dialogs. The class type for the MS Office dialogs is "bosa_sdm_Microsoft Office * " , where the " * " stands for Word,Excel,Access etc. The MSDN states that The following are messages that a hook procedure can send to an Explorer-style Open or Save As dialog box. CDM_GETFILEPATH CDM_GETFOLDERIDLIST CDM_GETFOLDERPATH CDM_GETSPEC CDM_HIDECONTROL CDM_SETCONTROLTEXT CDM_SETDEFEXT But unfortunately sending these messages using LRESULT SendMessage( HWND hWnd, // handle to destination window UINT Msg, // message WPARAM wParam, // first message parameter LPARAM lParam // second message parameter ); won't do any good in case of Microsoft Office dialogs. The MSDN also doesnot state what messages I can send to the office dialogs from the hook function to manipulate them or retrieve retrieve information regarding the current folder/file path within the office dialog. So I am requesting everybody here to provide me the required guidance. I will be greatful if you people can provide anything useful.

Maybe they publish the information you need, but they're certainly not required to do so. Good luck! Mark Mark Salsbery Microsoft MVP - Visual C++ Re: Subclassing and hooking the Microsoft Office 2000/2003/2007 File Open / Save Dialog boxes using Win32 C code Force Code4-Aug-07 9:28 Force Code 4-Aug-07 9:28  Here are the basic steps as I understand them to "hook" a dialog in some application. I personally never use actual Windows Hooks, as from my limited experience, they are slow, with a lot of overhead, and complicated to discourage their use. The three basic things needed are: 1) DLL injection 2) Windows Subclassing 3) Hooking the application import table. The last item goes by different names and does not involve actual Windows Hooks. Maybe you know some of this already: First You need to inject your code into the process address space of the target application. This means putting it in a DLL and then calling some function InjectDLL(targ_hwnd,"mydll.dll"). There are numerous downloadable libaries for DLL injection. Do a search on CodeProject. Then, within your DLLMain, presumably you'll do a search for the main window of the target application, using FindWindow, or whatever. At that point, you subclass that window with your own WndProc. You do this by calling SetWindowLong with the appropriate parameters. You also need to save the previous wndproc it returns so you can call it from your own. Your new wndproc is a message handler, looking at messages before the existing WndProc recieves them. So your task is to hook into some dialog of this application. Presumably this dialog is activated from some menu item are tool bar button in the main window. Use SpyXX to find out the message being sent to the Main Window when this toolbar button or menu item is selected. Then you will intercept that message in your new WndProc. When you receive that message all you will do is set some Boolean, say bFindFileDlg to TRUE. That brings us to the next step - hooking the application import table. If you can figure out how to get the Window Handle of the dialog through some message sent to the main window, then this step isn't necessary. All you need is the dialog hwnd so you can subclass it, just like you subclassed the main window procedure. But if there is no such message, then you need to find this dialog hwnd by intercepting the Win32 calls that are made it initialize any dialog. For examples, you could replace SetDlgItemText (likely to be called in any dialog box init), with your own version, which could go like this: WINUSERAPI BOOL WINAPI r_SetDlgItemTextA(HWND a,int b,LPCSTR c) { if (bFindFileDlg) { char txt[80]; GetWindowText(a, txt, 80}; if !strcmp(txt,"File Open") { SetProp(a,"PrevWndProc",(HANDLE) (WNDPROC)SetWindowLong(a, GWL_WNDPROC, (LONG)MyDlgProc)); bFindFileDlg = FALSE; } return SetDlgItemTextA( a, b, c); } Now you need to inject the function above in the slot of the app's import table for SetDlgITemTextA. Again there are many libraries to do this. For example, there is HookImportFunctionByName. However, note that this function only hooks the import table of one specific exe or dll you specify. What you want is a recursive version that replaces the entry for every DLL loaded by the application. In all liklihood, the main exe isn't making the call to SetDLgItemText directly, but rather throught some dll (e.g. MFC). I had to write my own recursive version of HookImportFunctionByName but undoubtedly there's something out there already written that does it for you. To know what win32 calls are being made, it helps to have a debug version of it, or write your own, hooking every single win32 call. There's probably a half dozen other crucial issues to be aware of, but I guess you'll have to find those out for yourself. Well, one other thing. In your subclassed WndProc, make sure to restore the original WndProc in the WM_DESTROY message.

If you know MFC calls, and their parameters, you can hook the import table for them in the same way. Also, the executable format is the same for all windows binaries, regardless if they're .NET, managed, or whatever - at least that's my understanding. Everything is just a wrapper for the win32/platformsdk.

I appreciate your effort in helping me out. I have already implemented the hooking part as you have described and it is working well for application using the windows common dialog library. But in case of MS OFFICE dialogs and Browse for Folder dialogs things are becoming critical and confusing! My obstacle is to retrieve: 1.The current directory path of a selected file or folder within an MS Office File Open / Save dialog. 2.Is it possible to retrieve the current directory path , when no selection is made by the user ? Like when the dialog is just initialized or when the user changes directory using up and back button ? 3.To paste the retrieved directory within the filename textedit cum combobox of the dialog ? 4.How to retrieve the same information in case of browse for folder dialog. I used spy++ to detect individual controls within the office dialog. But it appears that the whole dialog is embedded within a single unit having CTRL ID 0 ! I cannot use MFC classes in this project. The project specs states that only Win32 C code is allowed.

(the last parameter of SetWaitableTimer() being set to TRUE should cause the reume from hibernation). When I manual start the PC, the timer has expired. Is there something that I'm not doing ?
