Path Problem

Dione (5)
hi guys,
i am a beginner in c++, so I faced my first problem relatively fast.

I want to access a .wav-file that is located in the sounds folder of the teamspeak-client.

I am able to get the appPath ("C:/Users/%user%/AppData/Local/TeamSpeak 3 Client") and I defined a second path ("sound/default/wave.wav").

How can I easily combine both paths that my result will be: "C:/Users/%user%/AppData/Local/TeamSpeak 3 Client/sound/default/wave.wav"?

thanks in advance!

You can use two strings and simply concatenate them together:

1
2
3
 
std::string one = "some";
std::string two = "thing";
std::string three = one + two; //"something"

    std::string one = "C:/Users/%user%/AppData/Local/TeamSpeak 3 Client";
    std::string two = "sound/default/wave.wav";
    std::string result = one + '/' + two;

When using the provided code I am getting this error:
http://www11.pic-upload.de/18.07.14/vsttvx4v7xwg.png

After that I tried to #include <string>, but then I got tons of errors:

Could you show your actual code, rather than an image. (in both examples you gave the error was not within the portion of code displayed).

The first error is shown in the first picture:
1
2
3
 
std::string applicationPath(appPath);
std::string restOfPath = "sound/default/talkpower_requested.wav";
std::string soundPath = applicationPath + restOfPath;


the other error is triggered in the following line:
 
 
#include <string>

and the results are the error shown in the second picture: (this is a defined/standard code, it's not written by me)

Thanks for the effort you made to post the code. What I meant previously was, when the compiler issues a message about errors in a standard header file, only on extremely rare occasions is that the actual problem, it is merely a symptom and the error is elsewhere, in a different file.

Because of the number of additional headers required, I've not been able to compile the code. However, it looks like you are using C rather than C++ and so rather than introducing std::string, it is probably simpler to continue to use c-strings, and in particular the strcat function.

Example, this could go in the function ts3plugin_onClientMoveEvent() instead of using std::string:
1
2
3
 
    char restOfPath[] = "sound/default/talkpower_requested.wav";
    strcat(appPath, "/");
    strcat(appPath, restOfPath);


after that point, the appPath should contain its original contents plus the required additional text. (I see no particular reason for the intermediate '/' to be kept separate, presumably it could be inserted at the start of restOfPath, which simplifies things slightly).

reference:
http://www.cplusplus.com/reference/cstring/strcat/

I Hope this helps.

I applied your suggestion to my code and ..... it perfectly works now :D
I was a little bit confused as on this screen: http://www11.pic-upload.de/18.07.14/vsttvx4v7xwg.png , it says c++ (right side --> properties).

thanks a thousand times ;)
