GetOpenFileName Hook
« on: January 13, 2018, 06:01:51 AM »
Hello

I read by Msdn i can Hook the Common Dialog Box (GetOpenFileName).

I Have look here and found Gunners example (10288_Custom_Open_File_Dialog)
http://www.masmforum.com/archive2012/10288_Custom_Open_File_Dialog.zip

The code is all clear but i need to hook the new Common Dialog Box (Vista or Windows 7)

I make this new look with this flag OFN_EXPLORER .
But if i use both have i no Placesbar (listview) left side with Desktop ,Network etc.

mov   ofn.Flags,OFN_EXPLORER or OFN_ENABLEHOOK

Have you any an idea ?

Regards,


six_L

The hook works in 32-bit code. FileOpen$() uses it.

hi,jj2007
tested again, the cDialogHook_2.exe can extract 32 and 64 bit dll or exe ICO.
attachment: there are some icons in win explorer.exe file.

Hi Six_L

I use OFN_EXPLORER for Vista look and Placesbar (listview) left side with Desktop ,Network etc.



But if i use a hook  mov   ofn.Flags,OFN_EXPLORER or OFN_ENABLEHOOK have  i the old style.

hi,ragdog
this was an old question. (http://www.masmforum.com/board/index.php?topic=14214.0).
Code: [Select]
x_OPENFILENAME STRUCT
lStructSize DWORD ?
hwndOwner HWND ?
hInstance HINSTANCE ?
lpstrFilter LPSTR ?
lpstrCustomFilter LPSTR ?
nMaxCustFilter DWORD ?
nFilterIndex DWORD ?
lpstrFile LPSTR ?
nMaxFile DWORD ?
lpstrFileTitle LPSTR ?
nMaxFileTitle DWORD ?
lpstrInitialDir LPSTR ?
lpstrTitle LPSTR ?
Flags DWORD ?
nFileOffset WORD ?
nFileExtension WORD ?
lpstrDefExt LPSTR ?
lCustData LPARAM ?
lpfnHook LPOFNHOOKPROC ?
lpTemplateName LPSTR ?
pvReserved DWORD ?
dwReserved DWORD ?
FlagsEx DWORD ?
x_OPENFILENAME ENDS
Quote
FlagsEx
Type: DWORD

A set of bit flags you can use to initialize the dialog box. Currently, this member can be zero or the following flag.

Value   Meaning
OFN_EX_NOPLACESBAR
0x00000001
If this flag is set, the places bar is not displayed. If this flag is not set, Explorer-style dialog boxes include a places bar containing icons for commonly-used folders, such as Favorites and Desktop.

Remarks
For compatibility reasons, the Places Bar is hidden if Flags is set to OFN_ENABLEHOOK and lStructSize is OPENFILENAME_SIZE_VERSION_400.

i used the x_OPENFILENAME STRUCT, my testing codes was either crashed or noactive.
i'll try to test again.

Hello Six

have you forgot the filebuffer?

And by your  includes set  Winver xxx

WINVER equ 0501h

include \jwasm\include\windows.inc
include \jwasm\include\CommCtrl.inc
include \jwasm\include\commdlg.INC
includelib user32.lib
includelib kernel32.lib
includelib comctl32.lib
includelib comdlg32.lib


Code: [Select]

BrowseFilename  db  MAX_PATH dup (?)

   lea rax, BrowseFilename
   mov ofn.lpstrFile, rax

I think this is it?

But i use not a Dlg template for browse, like Gunners example

Greets,
