I have created a C# windows form application in VS 2005 and when I tried to edit the source file when the program is running, I get a message saying "Changes are not allowed while code is running or if the option 'Break all processes when one process breaks' is disabled. The option can be enabled in Tools, Options, Debugging." I tried enabling and disabling this option, but I still get this message and can't edit my source file while the program is running. Is there an option that I can enable or disable in VS 2005 that will allow me to edit the source file while the program is running?

Hi Mark, thanks for the help, ListView_Scroll() solved the problem I asked. Now I have another problem, when I press the left or right arrow on the scrollbar, I don't receive any WM_HSCROLL messages. I need to check when the thumb is at the far right and the right arrow is press I need to check for newer data and when the thumb is at the far left and the left arrow is press to retrieve older data. Any suggestion why I am not receiving any WM_HSCROLL messages?

I have a Listview window with 10 columns. Data are display in the column going left to right with the newest data at the right most column. A horizontal scrollbar is automatically displayed at the bottom and the thumb of the scrollbar is at the left side. I want to put the thumb of the scrollbar to the right side so the when you go to that window you see the newest data first. I tried using GetScrollInfo() but I keep on getting "The window does not have scroll bars." from GetLastError(). I tried using SetScrollInfo() and passing in different values for nPos of the SCROLLINFO structure to see if it would move the thumb, but it doesn't seem to work. Does anyone know how you I get the thumb of the scrollbar to be at the right side?
