DisplayFromMetaFile

[MarcoLo]

The gdViewer shows Metafiles in a very good quality.

Unfortunately I have however a problem with the function DisplayFromMetaFile() from gdViewer. If I load alternating different Metafiles with DisplayFromMetaFile(), after approximately 30 repetitions, the GdPictureStatus "1 GenericError" or "2 InvalidParameter" is returned.

In the attachment is a sample VB6 program.

Excuse for my bad English.

Thank you for your support

Code: Select all

Private Sub Command1_Click()
    Static tNum As Integer
    Dim tGdPictureStatus As Long
   
    If tNum = 0 Then
        tNum = 1
        tGdPictureStatus = GdViewer1.DisplayFromMetaFile(App.Path & "\542654140D.wmf")
    Else
        tNum = 0
        tGdPictureStatus = GdViewer1.DisplayFromMetaFile(App.Path & "\542723140D.wmf")
    End If
    If tGdPictureStatus > 0 Then
        MsgBox "error: " & tGdPictureStatus
    End If
End Sub

Hi,

It is normal. You never close the displayed image before openning another one.

You have just to add a call to the CloseImage() method before loading image.
