This is an old project, more than 10 years old ! I was doing it for fun and never posted it because It was just for testing and learning purposes, you will see how I explain pointers to myself in the code and I'm sure some people will find this funny Anyway, I posted it today for the benefit of someone who asked me about some stuff on .NET and Delphi. I hope it's useful. Main.rar

Hi guys, could anybody explain how to build any kind of dynamic graphic illustrations?So how to do this and what do I need to do this? Example: Windows 7 has a little nice analog clock graphic you get to see if you press on the time in the taskbar and now I wanna have / build any similar clock like this but I dont know how I should do this.The first mind I had was to paint a clock picture in any paint app to have the analog clock background (not sure whether this is right) and to show this later in any dialog.As next step I need to build some diffrent clock pointers to show them on this clock anyhow etc.All in all I have no idea how the right way is and thats t…

Hi, I am coding a dll for patching a vmp target. Everything goes well but when I change the permission of codesection using VirtualProtect api the function failed and program crashed when changing dwords in Codesection. When I change the permission manually through ollydbg then it works. Anyone can explain it why?

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

Hi guys, so I have a new small problem I need to fix.The problem is that I use two libs in my project and in both are some same function names used and now I get the error message... error LNK2005: _inflateReset2 already defined in 123.lib(123.obj) ...etc ...both libs are from C dlls. So the first question is how I can add both libs (in MASM) who using some same function names?If possible.So I dont wanna change the function names of one dll and create again a lib you know.So what can I do in that case? Thanks

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…

Hi guys, so I got following problem.So you know the VLC player which you can also use to enter direct URL addresses of video files to play them.If I use this function then all is working well and the video will played normaly and liquid as it should.Now I wrote a WinSock code to download the bytes and write them into a name pipe handle created for VLC process and started the player via ShellExecuteEx.The VLC player starts and does play the video reading the bytes from pipe.All is working fine so far but the video dosent play liquid and it lags / jerky etc so its not good and also not playing same if I enter the URL in VLC.So I dont find the problem reason in this cas…

Hi again, I made a listview with seven columns and used LVS_EX_GRIDLINES.I also did subclass the listview.If I now add much entrys then I get a VScrollbar to see which I can move.If I now press on the bar free parts (not slider itself) then the slider jumps up or down etc and the problem now I get is that the GRIDLINES are doube to see in each line = the entrys itself are crossed out and its looks very bad and in this case I have to do any refresh.In my subclass I added now WM_VSCROLL message and added.. .if uMsg == WM_VSCROLL invoke InvalidateRect,hWnd,NULL ,FALSE invoke UpdateWindow,hWnd ...and the listview gets updated and the representation looks good aga…
