winforms - How to mix c and c++ form application in the same project? -

guys, i'm sorry bad english.

i want programme c programme c++ form application using in same project.

for example:

when clicked button send entered text c program. entered text within textbox in c++ form app.

c programme save text computer file operations.

so example:

textbox1="hello world" button=clicked string^ message = textbox->text; writerfunction(message); void writerfunction(char m[50]) { file *fp; fp = fopen("text.txt","a"); fprintf(fp,"%s",m); fclose(fp); }

it looks using c++ .net (managed c++) i'm guessing pointer operator. in standard c++ utilize '*' instead of '^'. please right if i'm wrong there.

two options.

you using managed c++ can phone call win32 api create work harder. if still intrested please check link. started. http://www.codeproject.com/articles/9714/win-api-c-to-net

but i'd suggest utilize c++ .net approach save string in file. google find many examples you. 1 start:

if want utilize old style c++ can mix c , c++ without problems. need import libs project. libraries:

c - stdio.h examples here (http://en.m.wikipedia.org/wiki/c_file_input/output)

c++ -ofstream: stream class write on files

-ifstream: stream class read files

-fstream: stream class both read , write from/to files.

more details here: http://www.cplusplus.com/doc/tutorial/files/

windows api - can utilize win32 api importing header windows.h

few examples here (http://www.daniweb.com/software-development/c/threads/31282/windows-api-functions-to-read-and-write-files-in-c)

good luck. if need more info please allow me know.
