Developed as a XP alternative to the Wang/Kodak controls for Windows XP. The Microsoft download page for this dll states the "Supported Operating Systems" is Windows XP, and that "Windows Image Acquisition Automation Library v2.0 is only supported on Windows XP with Service Pack 1 installed." The dll relies on GDI+ available under Windows XP. I have also received reports the dll can also be used on Windows 2000 systems, though possibly only those with the latest service packs. Please see the Comments below. |

Developers wanting to add image and image device control functionality to their applications will and to check out this new, redistributable dll provided by Microsoft intended to replace functionality introduced with the Wang and Kodak image controls provided in older versions of Windows. Prior to the introduction of Windows XP, the Wang/Kodak control and libraries formed part of the operating system installation (were not redistributable) and provided the only inherent means to offer imaging display and manipulation without relying on third-party controls. However, Kodak Imaging for Windows program and the related controls (ImgScan.ocx, ImgAdmin.ocx, ImgEdit.ocx, and ImgThumb.ocx) are not included with Windows XP. The readme file indicates the Windows Image Acquisition Library v2.0 is only designed to support the PNG, BMP, JPG, GIF and TIFF image formats. It should not be relied upon to support other formats, though they may appear to be supported depending on system configuration. The download contains the dll, help files, installation instructions and a rash of assorted VB-based demos (and no, it does not contain the image shown ... that's my desktop background): 30 Days With My School Refusing Sister New Exclusive -This is a story about the month I stopped being a student and started being a detective, trying to find my sister again. Week 1: The Fortress
The Pivot of Week Three: Rebuilding TrustDay 18: The Contract I skipped my afternoon study hall to stay home with her. I didn’t lecture. I just sat on the floor with a notebook. “Let’s make a deal,” I said. “No school. But also no rotting.” She looked at me suspiciously. “30 days,” I continued. “You don’t have to leave the house. But you have to do three things every day: Shower. Eat one meal with the family. And teach me one thing you learned online.” 30 days with my school refusing sister new Day 7 — Small Exposures But over these last 30 days, the dynamic has changed. We stopped trying to "fix" her and started trying to understand the environment. Here is what the last month has taught us, and why we are finally turning a corner. School refusal is not a discipline problem; it The Healing of Week Four: The New Definition of SuccessDay 25: Micro-Steps We started small. Day 25: Walk to the end of the driveway. Done. Day 26: Sit in the car for ten minutes with the engine running. Done. Day 27: Drive past the school. Don’t stop. Just look at it. She hyperventilated, but she did it. Day 28: Walk to the front gate at 3:15 PM—when no one was there. She touched the metal handle. Instructions for proper installation of the dll and the help files are included in the readme.txt located in the main installation directory. The readme.txt in the samples folder contains the information above. Developers using wiaaut.dll are granted license to freely redistribute the library with their application as detailed in the redist.txt file inside the zip. (Only this dll is listed in this file, so don't overwrite your VB directory's redist.txt with this file!) This file is provided by VBnet as a service to developers. Any support issues for this product should not be sent to VBnet. Download Microsoft Windows Image Acquisition Library v2.0 (520k) |

| Comments |
| If the file 'gdiplus.dll' is installed on a Windows 2000 machine but not properly registered, calls to wiaaut.dll (the imaging dll) will not work. After registering gdiplus.dll calls to wiaaut should succeed. |
