This is driving me crazy. I've made a header for my mainmenu wich contains a class. I've put a string in it and I'm trying to assign it in my constructor. The compiler swallows it, doesn't complain and runs the program, but the string stays empty. What am I doing wrong?

GlobalHeader contains <string> btw



I tried every combination of Name =.

Can you post the implementation of the constructor (or at least the part where you assign the string)?
(as I've done something similar a couple of times, IIRC, and it worked fine)

Hmm, you say you've tried other namings like m_Name?
Hmm...

Are you assigning like:


Or are you assinging like this:

I tried both ways, but they won't work when i debug it keeps comming up with:

+ Name {???} std::basic_string<char,std::char_traits<char>,std::allocator<char> >
In the debug window.

Change your string definition in your class to:

std::string name;

Do not use 'using namespace' in a header to avoid doing this, as this will cause you problems further down the line.

Wel I've changed it to std::string but it still doesn't.





BTW, my program locks up if I click the cross to close the window, any idea's?

How do you know for sure that the string is empty? Your syntax looks correct, for sure.

Add the following:

char *pszText = Name.c_str();

after stepping over that line pszText should be set to your string - I can't believe it would be anything else.

PS: O/T: As suggested before, probably better to use Hungarian notation, prefixing all member variables with m_

Nope, can't get it to work. Name.cstr() returns a const char* btw. Well when I've got school again I'll complain there, they hopefully know what to do.

I still can't get the program to close properly with the close window button though.

You need to call LoopSDK() in your main loop (where you sync), if you dont want your window to freeze when clicking on the close button. In combination with that you should call dbDisableEscapeKey(), cause it would freeze then also if u hit escape key.
(u still can use it in ur code)

with the string problem I cant help you sorry..

greets,
barnski.

Btw, use this to make it "non-const":
const_cast< char*>( Name.cstr())


Hmm, very strange, since I am here on this DGDK forums,
none had a problem like this, I am sure it is one tiny, ugly bug that hides somewhere...
Hahaaa, wait until the Lord gets you hehehe

If it still doesn't work, then you are either *not* including the string header, or some other error is causing it to not be included.
