We've created a new ActiveX that wraps GDPicturePro4 and GDTwain and runs from the web in IE6 and IE7. It works fine in Windows XP, but causes IE to crash in Windows Vista.
We removed all code except for a few lines in UserControl_Initialize, and IE 7 still crashes in Vista immediately after the "Before TwainGetDefaultSourceName" msgbox. This same code woks in IE 7 on XP.
- Code: Select all
Private Sub UserControl_Initialize()
MsgBox "Initialize Start"
Dim gdpStorage As New GdPicturePro4.Imaging
'Populate Scanners and select the default scanner in the combobox
MsgBox "new PicturePro4.Imaging object created"
Dim k As Integer
Dim sDefaultSourceName As String
Dim iDefaultSourceIndex As Integer
MsgBox "Before TwainGetDefaultSourceName"
sDefaultSourceName = gdpStorage.TwainGetDefaultSourceName
MsgBox "After TwainGetDefaultSourceName"
For k = 1 To gdpStorage.TwainGetSourceCount
If gdpStorage.TwainGetSourceName(k) = sDefaultSourceName Then
iDefaultSourceIndex = k
End If
cboTwainSource.AddItem gdpStorage.TwainGetSourceName(k)
Next
cboTwainSource.ListIndex = iDefaultSourceIndex - 1
End Sub
If it helps, the Vista IE Crash contains the following info:
