I need some help getting a edit window to select, copy and paste text.
An article on the subject would be helpful or an example of code.
Thanks

How do you mean ? You have an edit control and you want to select and copy text out of it ?

Hi guys, I have a problem concerning a constructor.
I have a code like this:
CClass *pClass;
pClass = new CClass();
pClass->CClass::CClass( param1, param2 );
CClass has 2 constructors, the first called with new, and the second one has to be called after it.
The VC compiler accepts this syntax, but GCC does not.
What can I do? Redesign won't work, I need it exactly like this!!
Thanks for advice,
Alex

Simply speaking, you can't. I am actually surprised that it compiles with VC++.
My programming blahblahblah blog. If you ever find anything useful here, please let me know to remove it.

I have to and I know that it works for GCC, too... I just don't know the syntax, that's the problem.

You are not really calling 2 constructors, you are only calling one, then calling an function, which happens to be an overloaded constructor.
Overloading functions is ok, but some compilers will complain if you try overloading a constructor. Perhaps you should create just the one and pass null values to the first call.
I'm curious to know why you need it to be like this?

CClass *pClass;
pClass = new CClass();
pClass->CClass::CClass( param1, param2 );
What is it you are trying to do here? You are creating a pointer to an object, calling its default constructor which should be
pClass = new CClass; then trying to call it's overloaded constructor. You can only call one of them, calling the second will only initialise a new object. I'm surprised this compiled.

nop walder, this line is correct.

you must know that some constructors can be declared as explicit, and such constructors cannot be called without parenthesis !!!!

there is no way to re-design it.. i need it exactly as i described!!! i solved the problem using inline assembler now, but it is not the best solution i think. The problem is not the overloaded constructor. the problem is, that the GCC does not want me to call a constructor.

You could try using 'placement new'.
e.g.
new(pClass) CClass(param1, param2);

Why would you want to do such a thing?

perhaps you could search google for some C++ tutorials, there are many tutorials available for both beginners and professionals, ranging from creating a simple text editor to reprogramming your mothers hairdryer.
This one here[^] covers most of the basics.

Hello all.
Let's assume I have commands like this:
"c:\Program Files\Product\command.exe" -arg1 -arg2
\\.\c:\Program Files\Product\command.exe -a 1
I would like to know how to extract the "command.exe" part from whatever possible command syntax Windows allows.
Thanks all.

Wont argv[0] give you the exe name .
int main(int argc, char* argv[])<br />
{<br />
char *exeName = argv[0];<br />
TCHAR szFileName[_MAX_PATH];<br />
_tsplitpath( exeName , NULL, NULL, szFileName, NULL );<br />
return 0;<br />
}
// after seeing michael answer it striked me you were looking for the exe name

Hi all,
have any of you had any experience coding debbuger traps? You know those pices of code which detect if somebody is trying to reverse engineer your app. I you have any code samples or links to useful websites dealing with this I would be very much appreciative.
Thanks in advance.

I have a library in a file libgsl.a, which I want to make use of in my .dll that I write in VC++. How can I actually force compiler to link it? I tried adding the path to additional library path, but I still get the "unresolved external symbol" error...

Try to use #pragma directives
The following pragma causes the linker to search for the Test.Lib library while linking. The linker searches first in the current working directory and then in the path specified in the LIB environment variable.
#pragma comment( lib, "Test" )

Hi.
I dynamic append some item in a popup menu
AppendMenu(hMenu, MF_STRING | MF_ENABLED, 1000, "111");
but why the menu item is gray and disabled, cannot click.
I use Win32 C++(not MFC).
thanks.

Yes by default all these handlers are disabled unless you activate it through the command_UI handler .check enablemenuitem.
// try insertmenu or insertmenuitem
