Mail program

seems like you''re handling the files in text mode... do all operations in binary mode

GA

How do I do that??

if you''re using standard c file handling routines, using fopen(char *filename,char *openmode) to open/create files, add a ''b'' to the openmode string... do reads and writes with fread and fwrite..
if you don''t know how to use them, have a look at MSDN (i suppose you have got it with visual c++).

Correct me if im mistaking, but I think this is all you need:

FILE *file = fopen(filename, "rb") //rb for read in binary mode

Edit: Yeah like ga said. We must have posted at the same time.

I do. Here''s my source to read the file:
FILE* file = fopen("F:\\Setup.exe", "rb");
if(file == NULL)
return 0;
fseek(file, 0, SEEK_END);
int nSize = ftell(file);
fseek(file, 0, SEEK_SET);
char *pText = new char[nSize];

fgets(pText, nSize, file);
fclose(file);
Send(mail, (char*)Base64::Encode(pText).c_str());

The length of pText will become 3 with this code...

fgets() is used to read lines of text...

You should be using fread() instead... it''s binary safe, you pass it a file handle, a buffer (pText), an element size (sizeof(char)) and a length (nSize) and it will read the whole file to the buffer.

No, It''s just a home-made function...

Doesn't work. When I use:
int a = strlen(pText);

a will become 3. I don't understand it :S

to get the size of the file you will need to use fseek() with SEEK_END to go to the end, than use ftell() to give you the size

That''s what I am using. I now use this source:
FILE* file = fopen("F:\\Setup.exe", "rb");
if(file == NULL)
return 0;
fseek(file, 0, SEEK_END);
int nSize = ftell(file);
fseek(file, 0, SEEK_SET);
char *pText = new char[nSize];

fread(pText, sizeof(char), nSize, file);
fclose(file);

And still, strlen(pText) = 3. Also when I use Base64::Encode(pText), the output becomes far to small for the size of setup.exe.

OK. Ive found out that the data is read without problems. The functions Base64::Encode stops with chr(0), %00, 00h, etc. This functions uses a std::string, so I think that's the problem... How can I fix THIS?!

Is there a base64 encode function without std::string?

The 4th character (0x00) is null terminating the string. strlen will look for that 0 byte to determine the end of string. I''m assuming that c_str is doing something similar.

For example, printf("foo\0bar") will only print foo because \0 terminates the string.

Try working with the data using functions that don''t deal with strings. Instead of storing it in a string, just allocate a buffer, pass buffer to Send function. Of course, doing this, you will have to store size of the buffer.
