Re: Displaying high-res images in .NET?
Posted by Bob Powell [MVP] at 4/24/2008 9:18:53 PM
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 >>

Displaying high-res images in .NET?
Posted by Usenet User at 4/24/2008 5:48:51 PM
..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 >>

At least, potential solutions such as MapViewOfFile aren't very accessible
from C#.

I have added some additional logging to the app and can still not find the

The version in the c:\temp directory is not auto closing.

Re: Application start-up events without start-up form
Posted by Bill McCarthy at 4/24/2008 2:20:37 PM
What is it you are trying to do ?
If you want to change the startup from at runtime you can do that in the
Startup event by setting Me.MainForm to the appropriate form.

How can I get rid of the start-up form as I can't select the Sub Main when

Hi Carlos,
You can remove the WS_CAPTION window style from the Form1 to get what you
want. To do this, override the CreateParams property of the Form1 and
remove the WS_CAPTION window style from the original window style.
The following is a sample:

Re: DPI issues
Posted by RobinS at 4/23/2008 11:53:45 PM
Did you ever figure out how to do this? I'm having the same issue. When I
set the autoscalemode to DPI, it resizes stuff pretty well, except the forms
where we have hardcoded splitters. In those cases, I think I'm going to have
to calculate the positioning.

Re: Books recommendations please

The DataBinding book by Brian Noyes is awesome. You might also want to check
out Deborah Kurata's Doing Objects in VB2005. With that book you end up
building an entire application using business objects, including setting up
the stored procs for updating.
