Use API dialog box to store file path as a variable

[hawg1]

I pulled this code off of the MS knowledge database for using the API windows common dialog box to browse/select a file. It works great but it places the file path into a text box. I would like it to store the filepath as a variable for use later on in the database session.

Ideas on how that can be done? I know I have to declare a variable but am unsure as to where to insert the call to store the data into the variable.

Thanks

What do you see when you make the change I have made below?

I think this will give you a hint on what to do.

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

Function LaunchCD(strform As Form) As String
    Dim OpenFile As OPENFILENAME
    Dim lReturn As Long
    Dim sFilter As String
    OpenFile.lStructSize = Len(OpenFile)
    OpenFile.hwndOwner = strform.hwnd
    sFilter = "All Files (*.*)" & Chr(0) & "*.*" & Chr(0) & _
      "JPEG Files (*.JPG)" & Chr(0) & "*.JPG" & Chr(0)
    OpenFile.lpstrFilter = sFilter
    OpenFile.nFilterIndex = 1
    OpenFile.lpstrFile = String(257, 0)
    OpenFile.nMaxFile = Len(OpenFile.lpstrFile) - 1
    OpenFile.lpstrFileTitle = OpenFile.lpstrFile
    OpenFile.nMaxFileTitle = OpenFile.nMaxFile
    OpenFile.lpstrInitialDir = "C:\"
    OpenFile.lpstrTitle = "Select a file using the Common Dialog DLL"
    OpenFile.flags = 0
    lReturn = GetOpenFileName(OpenFile)
        If lReturn = 0 Then
            MsgBox "A file was not selected!", vbInformation, _ 
              "Select a file using the Common Dialog DLL"
         Else
            [COLOR=Red]Msgbox OpenFile.IpstrFile[/COLOR]
            LaunchCD = Trim(Left(OpenFile.lpstrFile, InStr(1, OpenFile.lpstrFile, vbNullChar) - 1)) 
         End If
End Function

Darbid,

It gives me a compile error message stating that "method or data member not found". While the message box is open, the ".Ipstrfile" is highlighted blue. After clicking OK, "Function LaunchCD (strform as form) as String" is highlighted yellow.

I do not wish at this time to open the file, just store the file name in a variable so that I can call it later on in code when needed.

IpstrFile >>> lpstrFile

Dim strPathAndFile As String


Private Sub Command0_Click()

    strPathAndFile = LaunchCD(Me)
    MsgBox strPathAndFile
    
End Sub

Thanks for the help. It worked fine.
