OllyDbg2 Issue - Table Window with Sorted Data
by akrutsinger- 3 replies

I'm developing another plugin for OllyDbg2 and for some reason, after I populate my table with the sorted data (anywhere from 1,500 to 4,00 records or so), I can't use the scroll bar on the side of that window to scroll through all of the data. When I drag the scroll bar down, I can view through a small portion of the data (140 records); as soon as I release the left mouse button the scroll bar immediately returns to the top, but the view doesn't change. When I click to drag the scroll bar again, the view of the data automatically displays the first record at the top of the window and I can scroll through those first 140 records. Now if I use the Page Up/Down or Arrow Up/…

Hello Tuts4you, I created a function which adds a new section to a exe file. Everything seems to be correct, but the new file crashed after adding the new section. After some study, i found the problem is the SizeOfRawData, because when I zero this out, the file runs smoothly. So the problem is I don't know what Im doing wrong. Maybe someone could help me out with this? If you want to see an example of a crashing-file after adding the new section, see attachment. crashed_file.rar
