Then it's easy to calculate the offset and you know how much space you have left. But, if you use the default methods of writing files, then each line is not going to be the same length.

Your question is not clear. Are you saying you want to unload a DLL or are you saying calling Environment.Exit() from a dynamically loaded DLL doesn't work? If it's the former, feel free to browse Google[^] If it's the latter, there's little anybody can do without your code. FYI, I loaded an assembly using Assembly.Load, instantiated a type and called a method on it which called Environment.Exit() and the app was cleanly shut down. Again, you may want to post a code snapshot. Cheers, Vıkram. Be yourself, no matter what they say. - Sting, Englishman in New York.

just paste the code of the headers in which you have declared th variables.

no worries - just wanted to make sure we'd solved it :-) Christian Graus - Microsoft MVP - C++ Metal Musings - Rex and my new metal blog

i tried to use INVALID_FILE_ATTRIBUTES and it returns an error on compiling saying that it was an undeclared identifier and also tried checking for the other error code but that just gives me the same error message i have been having when the function is called in my program. i have the correct files being included into my program so i really am not sure why it wotn let me use INVALID_FILE_ATTRIBUTES. also from what i have noticed, it never returns either error message as it goes to the main body of the function like it should.

you right(of course in this thread it seems that my guess is ture)and i think he find problem.:)and i agree with GetDlgItem is returning null_** **_ whitesky

the way my app works is nothign really big and complicated, its just a simple program i made to mess aroudn with. i do not "install" it on a pc in any way, i just send it to friends to test if it works. basically you open the exe, go into a screen where you type in the dll to load and the program loads it. its not complicated at least not in my eyes. i did notice that on my pc loadlibrary call is all i need to load the dll file, i do not have to get any addresses to the functions. but when i tell it to do that it crashes after i close the dll. my consoel based version works perfectly on any pc yet migrating the whole thing over to gui based seems to have changed how it does the loading of my dll files.

you have to modify your code for using MFC: CPaintDC dc(this); HDC mdc; HGDIOBJ obmp; BITMAP bmi; if((HBITMAP)m_hbmp && ::GetObject(m_hbmp,sizeof(bmi),&bmi)) { mdc = ::CreateCompatibleDC(dc.m_hDC); obmp = ::SelectObject(mdc,m_hbmp); ::BitBlt(dc.m_hDC,offsetx,offsety,bmi.bmWidth,bmi.bmHeight,mdc,0,0,SRCCOPY); ::SelectObject(mdc,obmp); ::DeleteDC(mdc); } Please mark your code as 'code'.

Here's one way (I assume you want to load from a file): 1. Add a picture control to the dialog, be sure to set its type to "bitmap". Change to ID to something meaningful. 2. Using the ClassWizard add a member variable of type CStatic for the control, call it m_Picture. 3. Add the following to your class declaration: HBITMAP m_hBM; 4. Add the following code to the dialog's OnInitDialog handler: HBITMAP m_hBM = reinterpret_cast<HBITMAP>(      LoadImage(          NULL,          _T("C:\\130x130.bmp"),          IMAGE_BITMAP,          0,          0,          LR_LOADFROMFILE      ) ); m_Picture.SetBitmap(m_hBM); 5. Add the following in a WM_DESTROY handler: DeleteObject(m_hBM); Steve

thank you, that worked exactly as i was wanting it to:-D

Whatever result you are seeing that happens to look correct is pure coincidence. The correct way to do this is: extern "C" __declspec(dllexport) void firstn( LPSTR lpFirst ) { printf("What is your first name: "); scanf("%s", lpFirst); // could potentially overflow (exercise for reader) } extern "C" __declspec(dllexport) void firstlast( LPCSTR lpFirst, LPCSTR lpLast) { printf("Your first and last name is %s %s.", lpFirst, lpLast); } "Opinions are neither right nor wrong.
