Thread: Help please: Using I/O to Send Compiled Files

Hi (to those who enjoy a greeting),

I need help with a task dealing with I/O streams that isn't covered in any basic tutorials or the book I have. My problem is that I need to use a program (compiled from c++ of course) to send a file that will also function as a program to another area of my computer or network. Basically this:

MY COMPUTER --main program--> NETWORKED COMPUTER

MAIN PROGRAM (on networked computer) --accessory program--> DIRECTORY (on networked computer)
Please note: There can't be any calls to copy a file or program from my computer to the other. It must all be rapped neatly in the main program.

I have tried many things, some of which don't make sense (I got frustrated). I have already tried sending a function to another location by this code:

Code:

otherfile << function(parameters);

However, as I predicted, it sent the returned value of the function rather than the function itself after compilation.

Please help!

Not sure I entirely understand your issue. You want to send a exe file (that is compleat binary) across a winsock connection, to arrive on another computer to be executed?

Well, I'd like to think that the way hex editors do it, is actual binary read and write. So, I would assume you'd open the file in ios::binary and send it over the winsock/network connection, and then save it as it comes in.

Thanks Marek, I will try that.

Since the streams are NULL terminated, you should probably stop sending the data on the NULL character, so that when it sends it automatically, it already has it in there and the file doesnt save with two NULL char's. Generally, when you try doing somthing like so, it doesn't save exactly the same and causes errors. But, That's all a matter of how you go about doing it too.
