why this code not playing voice of cat i.e. when selected CAT from ListBox and p

[texus]

Which part about the file handling isn't working exactly (the code looks good at first sight)? Does the text file get written correctly? What gets placed in the list box when trying to load from a file?

If you want to store the animals, even after the program has quit, then there is no other option than storing it in a text file on the hard disk.

I put some animal names in the text file and read them from file into listBox's additem function one by one ;and it is going well  ... now i want to write all items of listBox into the file as you suggest me and give me piece of code ... but it's not working well , it is giving some kind of compiler/syntax error !

std::ofstream ofile("animals.txt");
if (ifile.is_open())
{
    auto& items = listBox->getItems();
    for (auto& item : items)
    {
        ofile << item.toAnsiString() << std::endl;
    }
}

Print screen's of errors !

I edited my post later because I realized that this was going to happen. VS2010 has only very limited c++11 support.

Edit: just realized that that for loop is only supported since VS2012. It will be like this for you:

for (auto it = items.cbegin(); it != items.cend(); ++it)
{
    ofile << it->toAnsiString() << std::endl;
}

[Nabeel Nazir]

hi, check please what i am doing wrong, it's not working well, means animal name will be added but when window get's closed and again i run the code there is no recently added animal name!

You are writing to the file every frame.

You should move the code that opens and writes to the file to after the "while (window.isOpen())" loop.

now i am writing this at the end i.e. out of while (window.isOpen()) loop. ... it's still not working .. Please cehck it !

[texus]

- When creating the ofile, you are checking if the ifile is open. You should check ofile instead.

- Close ifile when you are done with it. It is automatically closed when going out of scope, but because everything is inside the main function, this will be when the program quits. And you don't want the file to still be open for reading when at the same time opening it for writing.

- The following lines don't work correctly.

while(!ifile.eof())
{
    ifile>>name;

You should change it to the following to get the desired effect.

thanks it's doing well ... now i have to do last requirement of my assignment ... which is to add a new animal name and press speak button so that the voice of newly added animal will be played automatically ... you gave me piece of code for this but it's giving some kind of debug assertion error at run time when i add new animal in edit box and press add animal button ! here is the code !

Ok, I figured out what is happening. You are loading stuff so you are adding items to the list box. But no sound is being loaded that belongs to these items. So the amount of items in the list box will be bigger than the amount of loaded sounds.

So instead of just adding the read line to the list box, you should also load the corresponding sound.

while(ifile>>name)
{
    ifile.ignore(10,'\n');

    // Do something here similar to what you do when pressing the 'add animal' buttons.
}

i didn't get it properly !

[texus]

You don't just have to load the animal names from the text file, you also need to load the sound that belongs to the animal.

Something like this (untested)

while(ifile>>name)
{

The "if(callback.id==1)" part in your code still contains old code. You should clean up your code a bit more, because you aren't using half of the code anymore.

You now simply need something like this:

You commented out too much code when callback.id is 2. You should still add the sound to the list when clicking the 'add animal' button.

I removed some of the commented parts during searching for the mistake.

i have copied your code in last reply  ... nothing is going so well ...

[texus]

I can't test it now, I'm not at home.

Try with your old code and look at what I changed in the part where callback.id is 2.
Maybe I just removed a little too much.

I just placed comments in your code to make it more clear. But if there is still something specifically that you don't understand then just let me know.

{
    ofile << it->toAnsiString() << std::endl;  // Write the item in the list to the file ( '*it' is a sf::String, and to write to a file you need an std::string which is why you need the toAnsiString function )
}

[Nabeel Nazir]

kindly explain auto keyword and toAnsiString() function more because i never use them ever before !

[texus]

For auto, you probably find better explanations when googling for it.
You can find some info here for example: https://www.cprogramming.com/c++11/c++11-auto-decltype-return-value-after-function.html

For the toAnsiString you can look at its documentation.
When writing to a file (or in the terminal), you can only use std::string. The sf::String class doesn't provide the '<<' operator which would allow it to be written to the file. So you need to convert the sf::String to an std::string first (which is what the toAnsiString function does) before writing it to the file. The reason I use sf::String instead of std::string is because sf::String also supports unicode characters, but as long as you don't use them then you don't have to worry about it and just use toAnsiString to get the std::string.
