I am currently in the process of migrating my organization from V8i to Connect. This includes the VBA that have been written over the years, most have been a non issue but there are some that used the Ken Getz code to call the cmdlg32.dll api to open and process a file, that draws out a bridge plot based on an in house geometry. I have gone through an added the needed PtrSafe to the declare function:
Declare PtrSafe Function aht_apiGetOpenFileName Lib "comdlg32.dll" _ Alias "GetOpenFileNameA" (OFN As tagOPENFILENAME) As Boolean
I have gone through and changed the declaration of tagOPENFILE name to:
Type tagOPENFILENAME lStructSize As Long hwndOwner As LongPtr hInstance As LongPtr 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 LongPtr lpTemplateName As StringEnd Type
I have gotten the program to run and not crash. But it fails to open the called dialog box. I have tried every different option I came across in my searches and nothing has worked. If anyone has another method to call an open file dialog in VBA or any suggestion on getting this to work it would be appreciated. My other option is to convert this program to .Net
I found the issue. It is when I initialized the tagOpenFileName. I had changed all the member names but did not change a single assignment type.
With OFN .lStructSize = Len(OFN) <--- this is now .lStructSize = LenB(OFN) .hwndOwner = hwnd .lpstrFilter = Filter .nFilterIndex = FilterIndex .lpstrFile = strFileName .nMaxFile = Len(strFileName) .lpstrFileTitle = strFileTitle .nMaxFileTitle = Len(strFileTitle) .lpstrTitle = DialogTitle .flags = flags .lpstrDefExt = DefaultExt .lpstrInitialDir = InitialDir ' Didn't think most people would want to deal with ' these options. .hInstance = 0 '.strCustomFilter = "" '.nMaxCustFilter = 0 .lpfnHook = 0 'New for NT 4.0 .lpstrCustomFilter = VBA.String(255, 0) .nMaxCustFilter = 255 End With
Thank you.lStructSize = Len(OFN) <--- this is now .lStructSize = LenB(OFN)
I was also missing the LenB.
