Another SystemParameter sInfo question

I need to disable the screen saver, due to an Excel "bug".

I thought I had the following code working, but now all I get is code 127.
I've searched the net and I don't see anything wrong with the following.
[DllImport("user 32.dll", CharSet=CharSet .Auto, SetLastError=tr ue)]
public static extern int SystemParameter sInfo(int uiAction, int uiParam,
string pvParam, int fuWinIni);

static void Main()
{
const int SPI_SETSCREENSA VEACTIVE = 17;
int screenStatus;
int retCode = 0 ;
screenStatus = 0; // disable screen saver
retCode = SystemParameter sInfo (SPI_SETSCREENS AVEACTIVE, 0, "0",0);
if (retCode == 0 )
retCode = Marshal.GetLast Win32Error ();
MessageBox.Show ("Screen saver not turned off","Screen Saver"); //Deactivate
screen saver
}

Thanks
Dwight

I'm also having the same problem - did you find a solution to stop getting the 127 error?

Please let me know if you have a solution

I'm using a SystemParametersInfo call to attempt to manage the screen saver. All I want to do is modify the ScreenSaveActive bit in the registry and have the OS recognize it (and occasionally set it back to -0-). Theoretically this should be easy to accomplish through the call shown below. If I trace the call with SysInternals (si)Registry Monitor I can see the call being made. Unfortunately in the si QueryValue for the key...

I need the csharp (C#) function for this API function: SystemParametersInfo(SPI_GETWORKAREA, 0, &rc, 0); Or must I pInvoke this (also)? My biggest problem with C# is to find the C# function for API functions? Is there any help for this available anywhere?

Hello, I want to change the keyboard language. Does anyone have an example code in VB6 for that? I know already from MSDN that it should be possible with the SystemParametersInfo and the SPI_SETDEFAULTINPUTLANG and you have to use the HKL. But I really do not understand how to do that. I would be very grateful for help! BigWilli

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
