Put a scanf before `strcpy(fileBuf[len++],"To: " TO "\r\n");` now merge the two strings.

ansh_kumar 20-Dec-16 2:43am View

Of course you can. Just change the code accordingly.

ansh_kumar 19-Dec-16 7:21am View

Don't include it. It no longer exists.

ansh_kumar 27-May-15 23:08pm View

The base64 method you are using is same as in solution 2. Moreover the no_of_rows in for loop in read_file is calculated before encoding the file whereas it has to be calculated after encoding the file so that all the encoded text is placed in fileBuf. See solution 3 how it is calculated after encoding the file. I think you were lucky with your file chosen.

Is the code working when you compile it as release version??

ansh_kumar 30-Mar-15 3:50am View

What's your email address?

ansh_kumar 4-Feb-15 3:10am View

I've already provided the link to the official website. The website contains source code and instructions.

ansh_kumar 4-Feb-15 2:08am View

You are using the wrong code.
For sending the image file use the code above it, which uses Imagemagick++.

Can you give me the file you are trying to send ?

ansh_kumar 22-Nov-14 3:42am View

I changed the code to send jpeg file. See my next solution below.

ansh_kumar 21-Nov-14 9:03am View

Actually this code is for sending text file only but I can modify it to send JPG file. Wait till tomorrow, I'll be coming with a solution. :)

ansh_kumar 21-Nov-14 0:39am View

Can you tell me the size of the file you are trying to send perhaps send me the image file you are trying to email.

ansh_kumar 5-Feb-14 3:07am View

Yes you were right buffer was overrunning, I've corrected it.

ansh_kumar 4-Feb-14 23:31pm View

yes there was a memory leak. I corrected that.
In the line

strcpy(fileBuf[len++],"To: " TO "\r\n");

I added

printf("TO: %d\n",strlen(fileBuf[len]));

and I'm getting
TO: 7616
which is not as expected.
Any guess ??

ansh_kumar 4-Feb-14 7:10am View

Thats what I'm searching, but no result till now...
In debug version it's only 31 (I guess)...

ansh_kumar 4-Feb-14 6:28am View

Wait I'm editing the question.

ansh_kumar 25-Jan-14 11:35am View

See my observation.

ansh_kumar 25-Jan-14 3:20am View

Yes I write it by myself...
Few improvements i found myself are:
1) First the base64 encode and decode functions are working absolutely well.It's the error in the read_file() and main() function.
In my update for the solution I put FEdata = read_file(); out of the while loop in the main() function because the file has to read only once.

2) It's the problem in data = FEdata[upload_ctx.lines_read]; in the while loop. I think in the 2D array (*FEdata)[] visual c++ is not putting '\0' after after reading the 54 chars from the file where as in mingw it does.

So when i write data = FEdata[upload_ctx.lines_read]; and use str = std::string(data); in the loop every time the whole 2D array is converted into the std::string which is what we see in the output.

I hope you are getting what am saying..

ansh_kumar 25-Jan-14 2:49am View

Can you suggest any improvement in the code???

ansh_kumar 25-Jan-14 2:36am View

See the following for the output from two compilers.
