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.
Don't try it, just do it!

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

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).

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

Hi FlyWithYou,
maybe it is some helpful to you
#define IDC_TEST 1000
HMENU hmenu,hMenu2;
hmenu=GetMenu(hWnd);
hMenu2=GetSubMenu(hmenu,0);
AppendMenu(hMenu2, MF_STRING|MF_ENABLED, IDC_TEST, "111");
case WM_COMMAND:
switch (wmId)
{
case IDC_TEST:
MessageBox(hWnd,"test",NULL,MB_OK);
break;
...

FlyWithYou
I tested for your question(why the menu item is gray and disabled, cannot click)
I write this code then test it and it's not gray
do you use this code?

Hello,
In addition to catching the WM_CLOSE event, I would like to disable the close icon on the dialog title bar when some critical section is being parsed in my application.
Is this possible?,
For those that use Nero Burning Room, when you are burning a CD/DVD, the close icon on the dialog title bar is dissabled.. How can be this done under MFC?

I guess that the style of the window is changed with SetWindowLong(), but I don't manage to find how.
Thanks in advance.
