[RESOLVED] object as data member having error

[Paul McKenzie]

i have deleted them

Why??

You need to understand -- unless you post the actual code you're compiling, we have no idea what you're actually compiling. Leaving out headers, include guards, types, etc. are important, as we don't know if these things you left out are causing the compiler error.

In your first post, you left out the terminating semicolon at the end of the class definition. That is a syntax error -- you don't think that's important??

CTspGAParams GAParameters;
this is the line where i get errors i have composed objects of same class in two other classes also but it always gives me same error, plz tell me how can i resolve this , i have to resolve it urgently plz.

[tspga]

is this possible that i mail you my project? if it is not possible i will send you all the complete header files with everything all guards headers etc.

[tspga]

have sent all the required code can u plz figure out whats te problem bcz i dnt knw what is problem in declaring member like that, i dont think there is some problem but i feel tat there is some header file problem either im adding wrong header file or missing some

[Paul McKenzie]

plz ... bcz

Please write proper English. Others who do not have English as their first language cannot understand what you're writing.

Second, I already stated that you should use code tags when posting code. Look at when I post code, and look when you post code. Do you see a difference? My code is formatted nicely, while your code is unreadable. Go back and fix your posts so that you use code tags.

And those of us for whom English is a first language just find it really annoying. We're adults here. You're not talking to your 12 year old friends in a chat room.

[tspga]

for those who are reading these replies because they are facing similar errors, i have resolved my issue what you can do is try naming your composed object variable with lower case letters, check for missing header files and lastly make sure that you have written proper constructor for initializing member variables of composed objects .
and to others i would like to just say thank you to make me learn that proper English should be used and code tags should be used.
regards tspga.
