From: Ivar on 16 Feb 2010 06:35 Hi all. Yes I am using good ol VB6. Can anyone do this and see if you get the same result. The example taken straight from AllAPI example of bringing up the open\save dialog box. I create a little exe and run it on Winders XP and Vista and all works as expected. But if I run the exe on my Winders 7 64bit machine where VB6 is not installed the program goes straight to the msgbox saying cancelled was pressed. Is this a Winders 7 issue or a 64 bit issue. Any suggestion for a work around AllAPI Example Code Below Thanks Ivar Option Explicit Private Declare Function GetOpenFileName Lib "comdlg32.dll" Alias "GetOpenFileNameA" (pOpenfilename As OPENFILENAME) As Long Private Type OPENFILENAME lStructSize As Long hwndOwner As Long hInstance As Long lpstrFilter As String lpstrCustomFilter As String nMaxCustFilter As Long nFilterIndex As Long lpstrFile As String nMaxFile As Long lpstrFileTitle As String nMaxFileTitle As Long lpstrInitialDir As String lpstrTitle As String flags As Long nFileOffset As Integer nFileExtension As Integer lpstrDefExt As String lCustData As Long lpfnHook As Long lpTemplateName As String End Type Private Sub Command1_Click() 'KPD-Team 1998 'URL: http://www.allapi.net/ 'E-Mail: KPDTeam(a)Allapi.net Dim OFName As OPENFILENAME OFName.lStructSize = Len(OFName) 'Set the parent window OFName.hwndOwner = Me.hWnd 'Set the application's instance OFName.hInstance = App.hInstance 'Select a filter OFName.lpstrFilter = "Text Files (*.txt)" + Chr$(0) + "*.txt" + Chr$(0) + "All Files (*.*)" + Chr$(0) + "*.*" + Chr$(0) 'create a buffer for the file OFName.lpstrFile = Space$(254) 'set the maximum length of a returned file OFName.nMaxFile = 255 'Create a buffer for the file title OFName.lpstrFileTitle = Space$(254) 'Set the maximum length of a returned file title OFName.nMaxFileTitle = 255 'Set the initial directory OFName.lpstrInitialDir = "C:\" 'Set the title OFName.lpstrTitle = "Open File - KPD-Team 1998" 'No flags OFName.flags = 0 'Show the 'Open File'-dialog If GetOpenFileName(OFName) Then MsgBox "File to Open: " + Trim$(OFName.lpstrFile) Else MsgBox "Cancel was pressed" End If End Sub

It won't always appear if the initial dir is inaccessible. Try checking Err.LastDllError to see why it failed. -- Dee Earley (dee.earley(a)icode.co.uk) i-Catcher Development Team iCode Systems
From: Ivar on 16 Feb 2010 07:48 Done a bit more digging CommDlgExtendedError returns 2, = CDERR_INITIAZATION According to MSDN CDERR_INITIAZATION = The common dialog function failed during initialization. This error often occurs when sufficient memory is not available. Can anyone else duplicate this. Ivar

That code worked fine for me on Win7 64 bit. -- Mike

I installed VB6 on to my new machine, I click on File\Open and nothing happens, no dialog box appears! Looks like MikeD was right, it's a Winders thing. Anyone got any idea what I can do to fix this? Thanks Ivar |
