Note You can find the sample code to load a picture in the Form Current event procedure of the frmEmployees form. The sample printed here includes only the code to load the picture. The actual procedure includes additional code that tests the authority of the logged-in user and enables or disables editing accordingly. The code first checks the form s NewRecord property to see if the user has moved to a new row that won t have a picture path stored yet. If so, the code hides the image control, sets the caption of an informative label (the lblMsg control) behind the image and makes the label visible, and then exits the procedure. When not on a new row, the code checks to see if the Photo field that contains the picture path is empty. If so, it hides the image control and displays the message as though the form is on a new record. If there s something in the path, the 874
Part 5: Automating an Access Application
Automating Your Application with Visual Basic code checks to see if a full path and file name are stored (a value containing a colon to indicate a drive letter, or a path containing the characters \\ that indicate a Universal Naming Convention path). If the Photo field does not contain what appears to be a full path, the code inserts the path of the current database in front of the file name. Finally, the code sets an error trap and then attempts to set the Picture property of the image control to the full path to load the picture into the control. If that fails, the code displays a warning message in the label behind the image and hides the image. If the picture load is successful, the code helps ensure that the colors in the picture are true by setting the form s PaintPalette property equal to the color palette used in the image.
Deleting and Updating an Image Path
Clearing the file name saved in the record is the easy part, so let s take a look at that first. Behind the Delete button that you can see on the frmEmployees form, you can find the following code:
Private Sub cmdDelete_Click() User asked to remove the picture Clear photo Me.txtPhoto = Null Hide the frame Me.imgEmployee.Visible = False Clear the image Me.imgEmployee.Picture = "" Set the message Me.lblMsg.Caption = "Click Add to create a photo for this employee." Make it visible Me.lblMsg.Visible = True Put focus in a safe place Me.FirstName.SetFocus End Sub
Private Sub Form_Undo(Cancel As Integer) Dim strPath As String User trying to undo changes. See if we need to reload the picture See if Photo has changed If Me.txtPhoto = Me.txtPhoto.OldValue Then Nope - nothing to do Exit Sub End If Try to load image - set error trap On Error Resume Next If nothing in the photo text, If IsNothing(Me.txtPhoto.OldValue) Then
