Every editable bound control on a form has an OldValue property that tells you the value of the control before the user changed it. When the user hasn t changed the value, the OldValue of the control equals the current value. So, this code checks to see if there s a picture path in the OldValue property of the Photo field that s different from the current value. If so, the code uses the OldValue to reload the picture. The last tricky part is to provide the user with a way to enter the picture path to add or update a picture in a record. Although you could certainly use the InputBox function to ask the user for the path, it s much more professional to call the Windows Open File dialog box so that the user can navigate to the desired picture using familiar tools. The bad news is that calling any procedure in Windows is complex and usually involves setting up parameter structures and a special declaration of the external function. The good news is Microsoft Office includes a special FileDialog object that greatly simplifies this process. You need to add a reference to the Microsoft Office library to make it easy to use this object from the VBE window, choose References from the Tools menu and be sure the Microsoft Office 11.0 Object Library is selected. Once you do this, you can include code using the FileDialog object to load a picture path. You can find the following code behind the Click event of the Add button (cmdAdd) in the frmEmployees form:

Private Sub cmdAdd_Click() User asked to add a new photo Dim strPath As String Grab a copy of the Office file dialog With Application.FileDialog(msoFileDialogFilePicker) Select only one file .AllowMultiSelect = False Set the dialog title .Title = "Locate the Employee picture file" Set the button caption .ButtonName = "Choose" Make sure the filter list is clear .Filters.Clear Add two filters .Filters.Add "JPEGs", "*.jpg" .Filters.Add "Bitmaps", "*.bmp" Set the filter index to 2 .FilterIndex = 2 Set the initial path name .InitialFileName = CurrentProject.Path & "\Pictures" Show files as thumbnails .InitialView = msoFileDialogViewThumbnail Show the dialog and test the return If .Show = 0 Then Didn t pick a file - bail Exit Sub End If Should be only one filename - grab it strPath = Trim(.SelectedItems(1)) Set an error trap On Error Resume Next Set the image Me.imgEmployee.Picture = strPath Make sure that "took" OK If Err = 0 Then Got a good file selection ... See if the photo is in a subpath of this project If Left(strPath, Len(CurrentProject.Path)) = CurrentProject.Path Then Strip it off and store a relative path strPath = Mid(strPath, Len(CurrentProject.Path) + 2) End If Set the path in the record Me.txtPhoto = strPath Hide the message Me.lblMsg.Visible = False and reveal the new photo Me.imgEmployee.Visible = True Else Oops. Clear photo Me.txtPhoto = Null Hide the frame Me.imgEmployee.Visible = False Clear the image
