Ive made an interface for this windows application, I was wondering how I would go about connecting it to the sql server, or perhaps saving it to a notepad. What would I add to this to make it possible to save data from a session of the program I made?

[Airplaneman19]

I can't directly help you with the GUI, but I advise you to look up what MVC is. You should aim to seperate logic and coding as much as possible from the GUI, which is just is superficial part of your program. How I would do it in psuedocode/C++ is like this:

String data;

data = MyForm.TextArea.Contents;

FILE * myFile;

myFile = fopen("session.txt" , "w");

String finalString = "\n" + TodaysDate + "\n" + data + "\n" + "--END--";

if(myFile != null){

   fputs(finalString, myFile);

   fclose(myFile);

}

Edit 1: Oops, that was C. Here's C++:

#include <fstream>

#include <string>

int main(){

String data;

data = MyForm.TextArea.Contents; //I haven't looked at interfaces, but just access the text area.


ofstream myFile;

myFile.open("session.txt");

String finalString = "\n" + TodaysDate + "\n" + data + "\n" + "--END--";

if(myFile != null)

{

    myFile << finalString;

    myFile.close();

}


}

So basically your creating a file, opening it, saving to it, then closing it?

[Airplaneman19]

In the code I just showed you, it didn't create it, it just opened it. The file should be created before running your program. But otherwise, yes. Also, a thing I forgot to mention, I don't know how to get the current date and time but I'm assuming that you can find a way and convert it to a string for proper formatting. So when you open it again, you just have to go to the end of thefile and read the text from the second newline to "--END--". Personally, if it were C#, which I'm way more comfortable with, I wouldn't use a text file, I'd use it with an XML file which should be way more easy to read from and write to, but I don't know how in C++ (I'm still learning). But I highly recommend finding a way to use an xml file.

Ok, where do i put that in my code:

At the end before the last brace?

Edited by Braydon Vaughan, 16 August 2011 - 11:31 AM.

[Airplaneman19]

Put it before the second to last closing brace, which I assume to be the end of your Form class. Of course, the #include directives should be at the top of your file, and you should get rid of the "int main() {}".

[Braydon Vaughan]

Thanks but it did not work and I am not sure why.

[Airplaneman19]

Exactly what part of it didn't work? (Compiler messages)

When I run it, and put in the password no matter which password whether it is the correct, or incorrect one. explorer is shut down. How can i get it to go to the else statement if the correct password is inputted?
