Kernel Mode VS User Mode
by Aldhard Oswine- 2 replies
- 10.4k views
I think I've not seen a kernel-mode code. What is the difference between a user-mode program and kernel-mode program at code level? int main(){ puts("HW"); } It's simple user-mode code/program, is there something similar for kernel-mode code/program? What is a difference between writing user-mode and kernel-mode program? Are there same APIs, etc.

Hi guys, does anyone have any LZMA lib to decompress such code I can use with MASM?So zlib dosent work with LZMA. PS: Or if there is no lib then maybe the dll and function name/s I have to use.On my HDD I found just liblzma.dll & liblzma-5.dll with many export functions like lzma_stream_decoder but I am not sure which functions do decompress.So on the LZMA SDK site I didnt found that function etc and its also again in ccp etc you know.Maybe you can help again a little. Thanks

How to read a text line by line / CRLF?
by LCF-AT- 6 replies

Hi again, does anyone know any function/s to split a text file (any text of notepad etc) into single lines by CRLF? Example: I have simple textfile which has 10 lines (each line with return at the end / CRLF) and now I read the file into buffer via ReadFile API and now I got the whole text in buffer and now I need to check manually for CRLF at the end or not if not present etc.So is there any simple function/s etc I could use to get a entire line by line back?Maybe there is anything I could use and dont know yet. Thank you

Hi guys, I have a question again.I wanna create a new file via CreateFile + WriteFile which I then wanna execute via CreateProcess API.The problem I have that I dont get it work and always get a Sharing Violation Error on CreateProcess API.I would like to use the flag FILE_FLAG_DELETE_ON_CLOSE so that file gets deleted after handle is closed so that I dont need to handle it by myself anymore.But as I said,CreateProcess API does fail if I dont close the handle from CreateFile before but if I close the handle then the file gets deleted of course.So does anyone know whether there is way to handle it right with using FILE_FLAG_DELETE_ON_CLOSE + CreateProcess after?Creat…

Hi guys, I have again a little question and need some input from others.This time I would like ask how you do handle dynamic controls. Example: Just imagine you do create a tab control and each tab does show new controls like a listview / box and more and you can also delete and move tabs to other positions etc.The question I have is how to store all handles of all controls what does belong to one and same tab?Lets say you create a tab control with 5 tabs and 5 Listview controls then you can store all LV handles in a free section from first tab till last tab in a row.Now if you do move a tab to other position like in browser then you can also move the handles in…

Will get AssemblyName from a file name or from a byte array withouth loading the assembly. In Program.cs you will find a short example, all you have to do is call AssemblyNameInit.GetAssemblyName methods, and it will return an assembly name; you can also use AssemblyNameInit.GetAsmRefsAssemblyName to get AssemblyName array of referenced assemblies.
