c/c++ binary to string and vice versa conversion functions? - C / C++ / MFC Discussion Boards

Yes, I've tried splitting them and I get the same problem. This code is in a unix environment - I don't have the ability (or the time) to port it to VS. The vtable problem is usually a linker error, but I suspect there's something wrong with the class definition. I can't see what it is though.

Seriously, have you tried this without using the boost shared ptr? If that works then maybe it's the way you're using the smart pointer? I would try and break up that single line statement into *all* it's component parts and see if there's something weird going on there.

One other thought - do you implement the default constructor? You don't have any impl here, maybe that's the problem?

I know, g++ is not the most stress-free compiler...

I have tried breaking it up into a million little pieces, but I consistently get the vtable error. That's why I called this thread "VTable Madness". It's driving me insane.

Hmmmmm, it should be in there. If not, I've done it like this in the .h file:

CLatticeNode(void) {;};

Found it! Not the CONSTRUCTOR, but the virtual DESTRUCTOR wasn't implemented. Gah!

Awesome! I think I've seen a similar kind of error with VC 6, only it's occurs in the compile phase as opposed to the linking phase.

Yeah, truly annoying. THanks for the push in the right direction.

I'm having trouble finding a c or c++ function that will convert a string of 1's and 0's to a string of characters. I also need something that will do the opposite. I was just wondering if there is a class out there that will handle this. I really don't feel like writing my own, if I can find one that will do it for me.

Assuming you meant to its numeric equivalent, check out strtol().

There are plenty available (e.g., CP, Google), but writing your own will take all of five minutes. You'll spend more time than that searching (and then implementing).

Ok, four minutes if you don't do any simultaneous browsing or game-playing.

Hi i'm wondering if the console could be viewed in windows forms?

I'm not sure what the line would be to view the console.

Sorry to post this on this forum but the is best forum in terms c++ help.

Are you wanting to spawn, and view the output of, a console application from your code?

"Normal is getting dressed in clothes that you buy for work and driving through traffic in a car that you are still paying for, in order to get to the job you need to pay for the clothes and the car and the house you leave vacant all day so you can afford to live in it." - Ellen Goodman

"To have a respect for ourselves guides our morals; to have deference for others governs our manners." - Laurence Sterne

I have code that writes to a console but I can't see the console because it is a windows forms application i'm writing

I'm confused. If you are already writing to the console window, can't you just write the same text to some other location (e.g., a form)?

"Normal is getting dressed in clothes that you buy for work and driving through traffic in a car that you are still paying for, in order to get to the job you need to pay for the clothes and the car and the house you leave vacant all day so you can afford to live in it." - Ellen Goodman

The code that writes to the console is to connect to a server and I don't want that to be shown on the form for the user to see but in the background in a console. It connects to the server fine but just doesn't display in a console window.

How are you doing this?

I've wrote an interface using windows forms and when the user clicks a button on the menu then this executes code from another class that connects to a server. The code that connects to the server was originally a console application and I have incorporated that code into the interface.

I appreciate your help but I don't want to waste your time as I think this is not that important.

So what is it that you are expecting to be written to the console window?

This is what I expect to see in the console window:

I don't want this information to be displayed to the user on the form but as a background job in a windows console.

I'm just not sure why the console is not showing up.

Even if I just write a simply command in the form as:

<br />
Console::WriteLine(L"Hello");<br />

A console is not shown with the word Hello.

Sorry I’m going to be offline now and won’t be on until tomorrow. I would to thank you for looking into helping me with this problem.

Is this VC++? Managed?

I have a Visual C++ book that has windows forms in it but I think it goes under managed

So you might want to re-ask your question here. There are several ways to spawn a console window and write to it, so I can only surmise that managed vs. unmanaged code handles it differently under the covers.
