C / C++ / MFC

6-Apr-04 11:11

Anyone know where I can get my hands on some C/C++ (not Java) code to control an X10 device? I just want to be able to turn the device on and off by running a simple command line program, eg:

C:\> foo.exe ON
C:\> foo.exe OFF

There seems to be nothing available @ x10.com or SourceForge. Frown | :(

Thanks!

CString to DWORD ? INT ?

How do I convert a CString into a DWORD or to a INTEGER.

Basically suppose I have a function that returns a DWORD value , but the acutal value that I need to return is in a CString. (actually ...it is a number between 0 - 100)

suppose...

DWORD myfunc()
{
CString strVal="5.5";
DWORD retVal = {some how convert the strVal into an integer or DWORD};
return retVal
}

Use _ttol() to convert a CString to an int.

I'm trying to convert a "CString" not a "string"
dont' have to use a member fucntion on this object?

I thought I need to format it first?

Ravi Bhavnani6-Apr-04 11:31

CString strFoo = "1234";
int nFoo = _ttol (strFoo);
ASSERT (nFoo == 1234);

Very Simple Smile | :)

Convert CString to String and then to int/double(whatever)

DWORD myfunc()
{
CString strVal="5.5";
char *str;
//allocate equivalent memory for the character array.
//'+1' is the space for NULL CHARACTER str=new char[CString.GetLength()+1];
for(int i=0;i<CString.GetLength();i++)
{
str[i]=CString.GetAt(i);
}
str[i]='\0'; //NULL Terminate the string

return atol(str); //RETURN AS INT
//OR
return atof(str); //RETURN AS DOUBLE
}

I hope this solves ur problem.

Hi all,

I'm writing a simple dialog with a listbox in "report" mode. My problem is that in order for a user to select an item in the list, (s)he has to click on the 1st column in the list. Also, this will only highlight the first column and not the rest of the row. This is functional ofcourse but it would be nice the have the whole row highlited.

Any help would be greatly appreciated Smile | :)

clipped controls

Need help...
How can I make a CMonthCalCtrl created at runtime (with Create(..)) not clipped by the parent window?
I need to show a CMonthCalCtrl control, and need to show it outside the bounds of a CFrameWnd, but when I create and show it in a view, this is clipped by the parent.
I tried with SetWindowPos(&wndTopMost...) but nothing..
Can anyone help me?

Thanks, Paolo

There is one thing you should know before using the advanced controls like Date-time-picker in ur program.

You should Call this function when your program starts.(You have to do this in API programming, cant say for sure about MFC, just give it a try. Refer www.msdn.com[^] for detailed info)

BOOL InitCommonControlsEx(<br />
    LPINITCOMMONCONTROLSEX lpInitCtrls<br />
);

It registers specific common control classes from the common control dynamic-link library (DLL).
Parameters
lpInitCtrls
Address of an INITCOMMONCONTROLSEX structure that contains information specifying which control classes will be registered.
Return Values
Returns TRUE if successful, or FALSE otherwise

ShowWindow problem

reznod6-Apr-04 6:09

6-Apr-04 6:09

For some reason every time I call ShowWindow it just hangs and I never get control of my application back. This didn't happen just earlier today, I may have changed something, but I have it called in two places. I know that one of them (the first example) didn't get changed, so I know that it can't be what I changed.

Here is the code that (I have changed) calls ShowWindow:

bool BuildWindow()
{
 const LPCSTR pstrTitle = "Game";
 const LPCSTR pstrCaption = "Game";

 WNDCLASS pwdcWndSpec = 
 { 
  CS_HREDRAW | CS_VREDRAW, //Style
  WindowProc, //lpfnWndProc
  0, //cbClsExtra
  0, //cbWndExtra
  GetModuleHandle(NULL), //hInstance
  NULL, //hIcon
  NULL, //hCursor
  NULL, //hbrBackground
  NULL, //lpszMenuName
  pstrTitle //lpszClassName
 };

 if ( !RegisterClass( &pwdcWndSpec ) )
 {
  Console::WriteLine("Error: Unable to register window.");
  return false;
 }

 mhwdWndHandle = CreateWindowEx(
  WS_EX_TOPMOST, //dwExStyle
  pstrTitle, //lpClassName
  pstrCaption, //lpWindowName
  WS_POPUP, //dwStyle
  0, //x
  0, //y
 GetSystemMetrics(SM_CXSCREEN), //nWidth
 GetSystemMetrics(SM_CYSCREEN), //nHeight
  NULL, //hWndParent
  NULL, //hMenu
  pwdcWndSpec.hInstance, //hInstance
  NULL ); //lpParam

 if ( !mhwdWndHandle )
 {
  Console::WriteLine("Error: Unable to create window.");
  return false;
 }
 mhinWndInstance = pwdcWndSpec.hInstance;

 ShowWindow( mhwdWndHandle, SW_SHOWNORMAL );
 UpdateWindow( mhwdWndHandle );
 SetFocus( mhwdWndHandle );
 return true;
}

mhwdWndHandle - Global HWND
mhinWndInstance - Global hInstance

The other place I have it called is in a class I made to give better control of the console window (I have not changed):

void AdvancedConsole::SetWndState( enuWndState venuWndState )
{
 ShowWindow( mhwdWndHandle, venuWndState );
}

mhwdWndHandle - Class level HWND
enuWndState - Enumeration:

__value enum enuWndState
{
 wsHidden = SW_HIDE,
 wsMax = SW_SHOWMAXIMIZED,
 wsMin = SW_SHOWMINIMIZED,
 wsNormal = SW_SHOWNORMAL
};

Any help would be greatly appreciated.

Just out of curiousity are you doing anything in OnPaint event that would hang for certain inputs?

I am not doing anything with on paint. This is my window's call back function though:

LRESULT CALLBACK WindowProc( HWND vhwdWndHandle, UINT vuntMsg, WPARAM vwprParam, LPARAM vlprParam )
{
	Console::WriteLine("Handle message: {0}", Convert::ToString(vuntMsg));
	switch ( vuntMsg )
	{
	case WM_KEYDOWN:
		if( vwprParam == VK_ESCAPE )
		{
            PostQuitMessage( 0 );
			return 0;
		}
		break;
	case WM_DESTROY:
		Console::WriteLine("Main window closed.");
		PostQuitMessage( 0 );
		return 0;
	}

	return DefWindowProc( vhwdWndHandle, vuntMsg, vwprParam, vlprParam );
}

I have found out that if I use a minimize action (SW_MINIMIZE, SW_SHOWMINIMIZED, or SW_SHOWMINNOACTIVE) with ShowWindow I don't have the hanging problem.

Thanks for the fast reply.

reznod6-Apr-04 7:47

By looking at what the console displays after I end the process that contains the hanging ShowWindow, I find that window is trying to process the following messages non-stop:

WM_SETCURSOR
WM_NCHITTEST

Hopefully this will be of some more help.

can you comment this line.

Console::WriteLine("Handle message: {0}", Convert::ToString(vuntMsg));

and check wheather it works or not... otherwize there seems to be no problem.
