Is there any function in vc++ do the same thing as the Input (int,int)
function in vb?
and is there one ... would someone please tell me what is it?
thanks in advance

Do you mean this function ?

Not exactly -- use ifstream declared in <fstream> file and its >> operator or getline() function to read data into a variable.

Here is one of many tutorials you can find on the net

excuse me ...but nothing shows when i pass or even press the "this function"
so i dont know the function u r talking about

thats what i was talking about
put i dont know how to replace this function in vb to vc++:

Public Function GetFile(Filename As String)
    Dim path As String
    Dim Fnum As Integer

    '---read file in one pass!
    Fnum = FreeFile
    Open Filename For Input As #Fnum
        GetFile = Input(LOF(Fnum), Fnum)
    Close Fnum

    Exit Function
    Err.Description = "GetFile: " & Err.Description & " -> " & File
    Err.Raise Err.Number

End Function

would u please tell me how?
thank u

Read the tutorial I posted and you will understand. It's a lot more complicated than VB. If you are going to write a c++ program then you absolutely must understand file i/o. Forget what you nearned from VB, C++ is completly different.

no ...its not like that at all
i found a tutorial to create ur own file type association in VB
(it was so hard to find in vc++)
and i converted with aprogram called(VBto converter) to vc++ code.
but i needed to modify some functions .... and one of them was (Input) and it is as i hope the last one....
i tried to reproduce the function body in vb into vc++

CComVariant Input(int numchars, int filenum)
	return Input_d(numchars, filenum);

CString Input_d(int numchars, int filenum)
	return "";					

but it does make link problem not when compiling BUT when running saying that
Form1.obj : error LNK2001: unresolved external symbol "protected: class ATL::CComVariant __thiscall CForm1::Input(int,int)" (?Input@CForm1@@IAE?AVCComVariant@ATL@@HH@Z)
Debug/File_Associate.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
i hope u get what i mean
any thing u can do to help me?
