I am using v13 and the LEADRasterView control. Is there a method on LEADRasterView.Raster to load a page of an image? TIA Gary Kindel Here is the current code used to display a single paged image:    Dim clcErrors As clsRLErrors     Set clcErrors = New clsRLErrors         RetrieveImageData = False         On Error GoTo SubRuntimeError       ChangeMouseCursor vbHourglass     LEADRasterView.MousePointer = vbHourglass       'First clear out any existing images     LEADRasterView.Raster.BitmapList = 0         'Initialize data control     dcImageView.ConnectionString = gcnDocMgt.ConnectionString     dcImageView.RecordSource = "SELECT DocMgtImageID, ImageData FROM tbDocMgtImages WHERE ImageSetID = " & SqlNumber(mlImageID) & " ORDER BY PageNumber"     dcImageView.Refresh             LEADRasterOLEDB.Raster = LEADRasterWork.Raster     LEADRasterOLEDB.DataField = "ImageData"             'Store images in raster viewer     With dcImageView.Recordset         Do Until .EOF             LEADRasterView.Raster.InsertBitmapListItem .AbsolutePosition - 1, LEADRasterWork.Raster.Bitmap             .MoveNext         Loop     End With         'Set to first image     If LEADRasterView.Raster.BitmapListCount > 0 Then LEADRasterView.Raster.BitmapListIndex = 0         'Free up work raster control     LEADRasterWork.Raster.BitmapList = 0        dcImageView.Recordset.Close        RetrieveImageData = True    Report

If you have the pages in the same Database field, you can extract them to a memory buffer and then use one of the following functions to load the images -         LoadMemory method -         LoadArray method -         LoadBuffer method Qasem Al-Lubani LEAD Technical Support www.leadtools.com    Report
