Resets it to what?

I mean to restart the computer, like pressing start -> Turn off computer -> Restart

Try ExitWindowsEx(EWX_REBOOT).

shutdown -r[^]

virtual void BeHappy() = 0;

Shutdown -r

As someone else already suggested, you can use the command "shutdown -r" which will run just as though you used it through command prompt. An example:

void main()
{
	system("shutdown -r");
}

This will default to a 30 second timer before the computer begins to shutdown. With some effort, you should be able to find a way to decrease the timer, although I'm not positive.

EDIT: system("shutdown -r -t 10"); that will set the shutdown timer to 10 seconds, instead of the default 30. The command shutdown tells the computer what to do, "-r" is for resetting the computer, "-t xx" (-t 10) sets the time to the amount of seconds you indicate, so if your code were "system("shutdown -r -t 1");" The computer would start resetting one second after your program executes that line of code. Theoretically you can set it to 0 seconds, but I don't feel like testing that one Poke tongue | ;-P

i have my C++ code that i developed in Visual Studio 2008

the solution contains 4 projects

i want that code to be ported to LINUX. i know the linux complier is GCC and i have no clue how to do it. i think it is done using a makefile but still if u ppl can help me.

VS2008 does not have a "makefile" export; So, you'd better sit down and learn how to manually generate makefiles which is one of the devil created file format (IMO). You might be interested in using one of the many IDE available on linux (kdevelop, ... ) that should ease your pain by "wrapping" the makefile in a nice environment.

One the other hand, depending on how much your application is tied to Visual Studio and/or windows (API and framework) the makefile might be the least of your problem.

There are many tutorials and 'makefiles how to' on the web, see, for instance [^].

Vertical/Horizontal scroll bar not coming in CListCtrl

_T("No name")6-Apr-10 3:45

_T("No name")

6-Apr-10 3:45

hi,

i am trying to make a customized Clist control. i have written my Class derived from CListCtrl. The problem is in this Vertical scroll bar are not coming when i dynamically create this list control. if i create it in resource and use DDX_Control and take it as my class variable it works fine(scroll bar comes) but if i create control dynamically scroll bars dont come. This is the creation code

m_pList = new CCustomList(12);


    m_pList-&gt;Create(LVS_REPORT | LVS_SINGLESEL | LVS_EDITLABELS | WS_CHILD | WS_TABSTOP ,
                    CRect(0,0,620,100),this,IDC_LIST3);

    DWORD dwStyle = m_pList->GetExtendedStyle();
    dwStyle |= (LVS_EX_GRIDLINES | LVS_EX_FULLROWSELECT);
    m_pList->SetExtendedStyle(dwStyle);

please help if any one has any idea. i searched on net there are many ways to remove them but no solution how to show them.

Thanks

bm_setstate redraw not working

I want to emulate pressing a pushbutton.
I call SendDlgItemMessage(hDlg,IDBUTTON,BM_SETSTATE,TRUE,0L);
and then I have tried calling RedrawWindow(GetDlgItem(hDlg,IDBUTTON),NULL,NULL,RDW_INVALIDATE|RDW_ERASE|RDW_FRAME|RDW_UPDATENOW|RDW_INTERNALPAINT);
with various flag combinations, but the button will not redraw.
If I call MessageBox after the RedrawWindow, the button redraws, but I don't want to do that!
What am I missing?

Try the following scenario Smile | :)

...
  SendMessage(hBtn, WM_LBUTTONDOWN, MK_LBUTTON, MAKELONG(10, 10));
  RedrawWindow(hBtn,...);
  Sleep(100);
  SendMessage(hBtn, WM_LBUTTONUP, MK_LBUTTON, MAKELONG(10, 10));
...
}

virtual void BeHappy() = 0;

syntax error [modified]

I am getting the following error:
error C2143: syntax error : missing ')' before '&'

on building the below code:

typedef unsigned int uint4;
void	Find(uint4& a, uint4 b, uint4 c);
void    Find(uint4& a, uint4 b, uint4 c)
{
	. . . .
}

I do not see any error in code.
Any idea as to why this error is coming up?

                                       ^

What's the purpose of that comma?

Your code compiles fine with my C++ compiler (are you using a C compiler?).
Smile | :)

rupeshkp7285-Apr-10 23:07

yes I guess
how to find that in visual studio
I have written the code in a .cpp file

CPallini5-Apr-10 23:20

.cpp source files are compiled (by default) with the C++ compiler.

However, the default behaviour may be overriden by the /TC compiler option, see [^].

Thanks Pallini for the inputs.
I think I have got the bug.
Actually in the VC project the file where I had been calling the fn. is .cpp while I have define it in a .c file.
I guess this may be the problem.
