Set the background in LUA

[BeRnA]

In G3 with the WinLuaEx there was a function to set the background.
What is the function in G4? I don't found anything in win table...

You mean people actually used that function?? :)

We can add it if there is a need.

Oh Yes, please add it...
I have a site that create background with the combination of 9 traffic camera pictures, and I want girder to retrive that image from time to time, and set as my background...

ah, ok. What is the windows api call again?

I dont know what is the Windows API to change the background, but in the WinLuaEx plugin the function was SetDesktopBitmap(filename)

In the plugin source code:


int CLUAWindows::SetDesktopBitmap()
{
CString strError;

if (lua_gettop(m_pState) != 1)
{
strError.Format("This routine requires 1 parameter instead of %d",lua_gettop(m_pState));
}
else if (!(lua_isstring(m_pState, 1)))
{
strError.Format("The first argument must be a string instead of a %s",lua_typename(m_pState, lua_type(m_pState, 1)));
}
else
{
CString sFilename = lua_tostring(m_pState,1);; // .bmp filename
if (SystemParametersInfo(SPI_SETDESKWALLPAPER,0,(void *)(LPCTSTR)sFilename,SPIF_UPDATEINIFILE+SPIF_SENDC HANGE) != 0)
{
return 0;
}

LPVOID lpMsgBuf;
FormatMessage(
FORMAT_MESSAGE_ALLOCATE_BUFFER |
FORMAT_MESSAGE_FROM_SYSTEM |
FORMAT_MESSAGE_IGNORE_INSERTS,
NULL,
GetLastError(),
MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), // Default language
(LPTSTR) &lpMsgBuf,
0,
NULL
);

strError.Format("SystemParametersInfo() failed with a return of %s", lpMsgBuf);

// Free the buffer.
LocalFree( lpMsgBuf );
}

lua_error(m_pState, strError);
return 0;
}
