problem: Front end in C# and backend in C?

[siddharthmakwana]

Is it possible to connect front end created in C#(visual studio) to a C file as a back end...?
i want to make a MD5 sum calculator for which i have prepared GUI in C# and i do have a C code that generates MD5 sum of a given file or text. the C code takes the file path or string as a command line arguments.....

GUI consist of two text boxes. one to input filename or text and other in which MD5 sum should be printed...

yes
create the C code as a DLL project and use it in C# project
google on how to use C dll in c#

Or you can "execute a command" (your C program executable) passing the parameter and return the string which can be displayed in the text box.

Though I recommend to write the program in C# instead of using it as a command.

Any reasons ? I've always assumed that code is much faster when executed in C compared to modern high level languages...
And for a digest algorithm this should be a human noticable time difference for larger files right ?

That recommendation isn't because of the execution speed. But invoking (OS) commands from program is never considered as good option.

And BTW, read the following links please. Just for information.

it is always speed vs effort
in this case if he implements both UI n BL in C# , he will effort with no penalty in speed

i developed a form applic in C# for finding duplicate files using md5 Hash.

used the md5 security class

it worked out quiet nicely for large files also.

for files of 3 - 10 GB used file splitting method. will post src code if you like.

this is what i think is the best method for using c codes in other langs.

Great... Host the project on Sourceforge or Github or GoogleCode or CodePlex and please provide a link.
And BTW, under which license are you publishing your code? I'm just curious...

 

[arpanmukherjee1]

i did not create any class of my own, just used it.

i did it for request of friend of mine (avid collector of hindi songs) who was having same mp3 file multiple times over the drive.

i did not publish it anywhere, i will upload it to RS with src,(tomorrow)
change as u like

but tell me if u do smthing interesting with it

i think CRC32 is enough for this purpose.....

I will still insist to host the project on some site. It will be helpful for others as well as you for issue tracking and improvement.
