08-09-2007, 17:08 Joe Stanton Joined on 01-14-2007 Posts 4 Invalid File Format in v14 (worked in v12) I get "Invalid file format" error with the file attached. This file has been previewed before with LEADTools v12 software (ActiveX). I am now evaluating v14 for it's native .NET 2.0 support. This version of Raster Imaging Pro does not read this file type. It is sad that perhaps functionality has been lost instead of gained over the years, but perhaps I have another problem you can see in my code and address. Simple code sample: Dim loCodecs As New RasterCodecs Dim lsFileName As String = TextBox1.Text Try If File.Exists(lsFileName) Then RasterImageViewer1.Image = loCodecs.Load(lsFileName) End If Catch End Try Results: ?err {Microsoft.VisualBasic.ErrObject} Description: "Invalid file format" Erl: 0 HelpContext: 0 HelpFile: "" LastDllError: 3 Number: 5 Source: "Leadtools" Please note that this file is a TGA though it's extension is 1. This file type is used in retail merchandising and the 1 means "front view of product".    Report

In my defense, your Image Processing example did not show that for different image formats the specific format library needed to be added as a reference. My assumption had been that they would find the needed code and work as previous versions of the software (ActiveX specifically) had. It should also be noted that your website documentation does not show that yout products supports .NET Framework 2.0, it simply says support 1.1.    Report

Currently, not all attachment types are allowed, so to ensure a file uploads correctly, you can put it in a .ZIP or .RAR archive. Some of the other allowed attachment types include .JPG, .GIF, .PNG and .TXT files. About the file format Codec DLLs, you don't specifically need to add them as references in LEADTOOLS 14, but you must have the DLL present in the path specified in the CodecsPath property. About the webpage that fails to mention .NET 2.0, could you please tell me what its link is? Amin Dodin LEADTOOLS Technical Support    Report
