OutOfMemory when saving imagein Richtextbox
I am using a richtextbox as a notes fields, which enable user to add image
now I get outofmemory error when saving the fields when it contains image with resolution 4800x2800,
error occurs on rtfText = Me.txtNotes.Rtf when I debug it
"An unhandled exception of type 'System.OutOfMemoryException' occurred in mscorlib.dll"
is there a limit to the size ? I am planning to limit the image to 1920x1080 but not sure how since it's returns OOM error before I can do anything (I think it's from richtextbox.rtf)
Would appreciate if I can get help to limit the image resolution that can be added
Private Function ValidateRichTextImage() As Boolean
Dim rtfText As String
Dim width As Integer
Dim height As Integer
rtfText = Me.txtNotes.Rtf
Dim widthRegex As New Regex("picwgoal[d]+")
Dim heightRegex As New Regex("pichgoal[d]+")
Dim widthmatch = widthRegex.Match(rtfText)
If widthmatch.success Then
Dim swidth As String = widthmatch.ToString.Replace("picwgoal", "")
width = Integer.Parse(swidth) / 15
End If
Dim heightmatch = heightRegex.Match(rtfText)
If heightmatch.success Then
Dim sheight As String = heightmatch.ToString.Replace("pichgoal", "")
height = Integer.Parse(sheight) / 15
End If
If rtfText.Contains("picwgoal") AndAlso width = 0 AndAlso height = 0 Then
Me.Errors.Add("P1MMO0001", , Tb.Errors.ErrorTypeType.ErrorTypeError, , )
Return False
End If
If width >= height Then 'landscape
If width > mcImageWidth OrElse height > mcImageHeight Then
