This is my dilemma. I developed one important app under Vista Ultimate with 1600x1200 screen resolution and intend to use this GUI in WinSer2008. Unfortunately the default setting resolution (1280x1024) herewith VGA color scheme with a vga driver vgapnp.sys. When you go to Display Settings==>List all Modes, 1600x1200 is not even listed. I decided to trick the system. Went to Vista, determined the driver there for the same monitor (I have two partitions on the same machine). That monitor driver is monitor.sys. Then I came back to WinSer2008, found the driver in the same directory: Windows\system32\drivers and tried to uninstall driver vgapnp.sys and replace it with monitor.sys. The system is looking for inf file, naturally, I found it in Windows\inf folder but the OS does not allow me to install it. It is complete run around. It is VGA or nothing. How can I do it? I need my 1600x1200 badly. The form isoff screeen partially and I have to maneuver it constantly to bring some parts into my looking area.Thanks.AlexB

Even if you could trick it to run at the same resolution, you can not guarantee that it will always be that way. For example, what if the computer your application runs on gets replaced or reformatted?I would suggest that you modify your application to calculate the screens dimensions and make it a certain size that you wish. In your code you should handle the resizing and size the controls properly. I believe you wrote your app in c#? If so, you'd have to make sure to dock and anchor and handle resizing events to make sure that your application can handle the different sizes. Look into the Screen class (Screen.PrimaryScreen.WorkingArea.Bounds or something like that)

Hi Alan, I am working on resizing all right. It is not the issue. I still want to exploit the highest resolutionthat my monitor offers. I have no plans to reformat the HDD. I am pretty certain it will be stable. Do you know how to do it?AlexB

hi alexbb,are you still stuck with the same error ?if not please let us know, we usually do not keep the threads open for more than a week, and i see that the thread is opened sincelast year, we are in the process of regressing the threads and if you feel your problem is not resolved we will further go ahead and troubleshoot the issue. Else we would mark the question as answer or mark the best possible action plan as answerthanks for understandingsainath windows driver development.
