..NET 1.1/2.0 I have a need to display high-resolution scrollable images in a .NET application (Windows Forms). One well known solution is to create a Panel with AutoScroll set to "true" and then add a PictureBox or another Panel to it, that is used to display the image. The above approach ...more >>

There are no real solutions to this problem. A 32 bit process has a 2 gigabyte address limit but in reality the usable limits of memory in a .NET program are somewhat less. GDI+ is not well suited to dealing with large images and certainly, a 14000 by 10000 full colour image would hit the s...more >>

Hi, C# .NET 2.0 I'm developing a windows application that will run on a number of machines typically with DPI of either 96 or 120. By setting the AutoScaleMode on different forms to DPI I get the required scaling results. However, I have one form that contains a richtextbox that's anchored t...more >>

You should document this on Microsoft's Connect site. After, you document it you can post a link here for us to vote.

I know. I could even measure printer output. But I wanted to find a specification, or someone who knew what it says. Is there such a specification that specifies the value? Or maybe a common known ratio of height to width? Thanks "Michael C" <mike@nospam.com> wrote in message news:eEO...more >>

Thanks for getting me started!
