I am using modeless dialog box in my application . But When I minimize Main Application the modeless Dialog Box also minimize . It is also not showing in the task bar to switch to modeless dialog . How to avoid the dialogbox to minimize with the main Application .also how to show it in taskbar
Well, thank you for such a detailed description of your problem!
Exactly how do you expect people to help you solve your problems without explaining what those problems are in detail. We cannot read your mind or guess at the results of your compilations or tests from thousands of miles distance.
Then what do you need? The previous answer is correct, and does answer your question. A virtual function is overridden, and the only way to access a base class implementation is to explicitly specify the base class as the other user has indicated.
sry for lame data structure but had to take like that
i've included it in my main.cpp
and thr's another header "simulate.h"
that needs to be included in "main.cpp"
now the problem is i have to include "shapes.h" in "simulate.h" too.. but when i do that i get error
1>simulate.obj : error LNK2005: "struct polygon pg" (?pg@@3Upolygon@@A) already defined in main.obj
1>simulate.obj : error LNK2005: "struct circles cl" (?cl@@3Ucircles@@A) already defined in main.obj
1>editor/Debug\editor.exe : fatal error LNK1169: one or more multiply defined symbols found
i tried removing "shapes.h" from "main.cpp" with "simulate.h" included in "main.cpp" and "shapes.h" included in "simulate.h" but still get the same error.
There are two ways to deal with this. One is to put the word "extern" in front of the declarations in the header file and then in one and ONLY one place (main.cpp most likely) add those declarations again without the "extern" in front of them.
The second option is to do this -
In the header file :
#define GLOBAL extern
// define structures here ...
// now declare instances
GLOBAL circles cl;
GLOBAL polygon pg;
Then in just ONE of the .cpp files, again like main.cpp, do this :
This scheme can work with virtually any global variables if you really need to use them.
If you have an unresolved external error from the linker then you did not do what I said to exactly. Copy and paste the two definitions I showed in the previous post and put them where I said they need to go and it should work fine. I have used this technique for a long time with several different compilers and not had any problems.
