Re: What means Paolo Messina1-Sep-01 0:46 Paolo Messina 1-Sep-01 0:46  Yes, I know that. You can see also in my demo project that the last item in the tree structure is a shared folder. You have to take the path of the shared folder and continue enumeration using FindFirstFile/FindNextFile (appending a "\*.*" or whatever mask you want to the path). Enumeration of local files/folders (even if shared) is not responsibility of the WNet APIs, but you have another way. Paolo ------ "airplane is cool, but space shuttle is even better" (J.

Can an ini file be encripted and still read and written using GetPrivateProfileString and WritePrivateProfileString thank you. Re: is this possible? #realJSOP29-Aug-01 5:28 #realJSOP 29-Aug-01 5:28  You can't encrypt the entire file and still have it work with Get/WritePrivateProfileString, but you *can* encrypt the data before saving it to the INI file, and decrypt it after reading. However, if one of the encrypted strings contains a semi-colon, you may not get all your data back because that character represents the start of a comment in the file. I would use a binary data file and encrypt/decrypt the data into/from there, or use the registry. Re: is this possible?

If not, I recommended you to read technical article from on MSDN from Dino Esposito: "A Programmer's Perspective on NTFS 2000 Part 1: Stream and Hard Link" It can give you one idea how to easilly do it without file encryption Martin ---> How to initialize the follow parameter in "NETRESOURCE"?

Maer Re: How to initialize the follow parameter in Paolo Messina29-Aug-01 12:43 Paolo Messina 29-Aug-01 12:43  I think you only need lpRemoteName and some flags. You may also consider to use the shell and SHGetDataFromIDList if you have a PIDL of the net resource. You may obtain that by parsing a network path with SHGetDesktopFolder and IShellFolder::ParseDisplayName. But it's surely easier to try with the first method Paolo ------ "airplane is cool, but space shuttle is even better" (J.

I have read the information about SHGetDesktopFolder, IShellFolder::ParseDisplayName, SHGetDataFromIDList in MSDN. Can you show me a sample code using the functions you mentioned before to get the first level of "NETRESOURCE" of the "Network Neighborhood"? Thanks again. Best regards. Maer Why add "WINAPI" ahead of a function? Maer72729-Aug-01 4:55 Maer727 29-Aug-01 4:55  (the follow is from MSDN) BOOL WINAPI EnumerateFunc(HWND hwnd, HDC hdc, LPNETRESOURCE lpnr); What is the function "WINAPI" here? Thanks. Maer Re: Why add Joaquín M López Muñoz29-Aug-01 6:05 Joaquín M López Muñoz 29-Aug-01 6:05  WINAPI specifies the calling convention of the function. The calling convention is the set of rules followed to pass arguments to and invoke a function. Some aspects a calling convention must define are Whether parameters are stored in registers or in the stack, the order in which parameters are stored in the stack (first parameter the first to be pushed or the other way round), whose responsibility it is to clean the stack after return, how the return parameter is passed from the function to the invoker. So, different languages typically specify different calling conventions (notably, the Pascal calling convention is that the callee clean the stack before returning, whereas in C it is the caller that does the job). If a function is invoked with a different calling convention than expected, crash is almost sure to happen. The language C (as implemented by Microsoft) allows the specification of the calling convention of a function so that you can invoke it even if it does not follow the C calling convention. Some calling conventions are: __cdecl, the C default calling convention, __stdcall, aka PASCAL, __fastcall, __thiscall, etc. WINAPI is simply a macro for __stdcall, and ensures that your program calls Windows APIs the Pascal way. Why do Win32 APIs use the Pascal calling convention instead of __cdecl? Remember that these functions inhabit global DLLs of the system and are invoked by different programs written in different languages, so they just had to stick to some particular convention. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: Why add Maer72729-Aug-01 20:02 Maer727 29-Aug-01 20:02  Thanks pal. I still have a question. In __stdcall calling convention, the callee cleans the stack, so it can not be a vararg function. In __cdecl calling convention, the calling function cleans the stack, so it can be a vararg function. I do not understand "the calling function cleans the stack, so it can be a vararg function" and "the callee cleans the stack, so it can not be a vararg function". Can you explain the mechanism of stack cleaning and vararg function? Thanks.

The exe file I have does not any window for which I can load a resource and assign an icon. It is a simple console based application calling a few functions and it does not give out any output on the console. Can anyone suggest me a method to do so. Thanks Vijay Re: Changing Icon for an .exe file Joaquín M López Muñoz29-Aug-01 6:10 Joaquín M López Muñoz 29-Aug-01 6:10  I don't have my Visual Studio handy, but all you have to do is insert an icon using the resource insertion menu (maybe under Insert/Resource). You'll be asked to confirm that a .rc and a resource.h be included in your project. This should suffice.

Sandeep Simple/Extended MAPI & CDO AJ12328-Aug-01 23:38 AJ123 28-Aug-01 23:38  Hi, I am just about to start some email integration development. Trying to choose between Simple MAPI, Extended MAPI and CDO. All i need to do is open a message to be sent, with attachments already added and the destination address to be filled in by the user. At the moment i am swaying towards simple MAPI. Is this still going to be supported in the long term, or is extended MAPI replacing it. Cheers Richard
