Ich habe folgendes vor:
-Pc(Windows 7) mit 3 Bildschirmen wovon jeweils nur einer gleichzeitig benutzt wird(also kein Clone, Extended)
-Per Commandozeile einen von den 3 Bildschirmen als Primären Monitor setzen.
Da dies unter WIn 7 wohl nicht so ohne weiteres Möglich ist, wollte ich hier mal nachfragen ob das mit dem UltraMon SDK machbar ist, und wenn ja, welche Funktionen muss ich da verwenden?

So I have writen al little test code to set the second screen as primary, but nothing happens.
I can read the information for both monitors, but the primary and enabled flag does not take any changes....where is the error?
Here is my code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using ULTRAMONLib;
namespace MonitorSwitcher
{
public partial class Form1 : Form
{
IUltraMonSystem2 sys = new UltraMonSystem();
IUltraMonMonitor[] mon;
int Monitoranzahl = 0;
public Form1()
{
InitializeComponent();
Monitoranzahl = sys.Monitors.Count;
mon = new IUltraMonMonitor[Monitoranzahl];
TextBox.Text += "Monitor Anzahl: " + Monitoranzahl + "\n";
for (int i = 0; i < Monitoranzahl; i++)
{
mon[i] = sys.Monitors[i];
}
}
private void btStart_Click(object sender, EventArgs e)
{
for (int i =0; i< Monitoranzahl;i++)
{
TextBox.Text += "\n";
TextBox.Text += "Monitor " + i + "\n";
TextBox.Text += "AdapterDeviceName: " + mon[i].AdapterDeviceName + "\n";
TextBox.Text += "AdapterName: " + mon[i].AdapterName + "\n";
TextBox.Text += "DeviceName: " + mon[i].DeviceName + "\n";
TextBox.Text += "RegKey: " + mon[i].DeviceRegKey + "\n";
TextBox.Text += "Enabled: " + mon[i].Enabled + "\n";
TextBox.Text += "Name: " + mon[i].Name + "\n";
TextBox.Text += "Removable: " + mon[i].Removable + "\n";
TextBox.Text += "Primary: " + mon[i].Primary + "\n";
TextBox.Text += "WindowsID: " + mon[i].WindowsID + "\n";
}
}
private void btMoni1_Click(object sender, EventArgs e)
{
if (Monitoranzahl > 0)
{
mon[0].Enabled = true;
mon[0].Primary = true;
TextBox.Text += "Monitor 1 Primary\n";
}
}
private void btMoni2_Click(object sender, EventArgs e)
{
if (Monitoranzahl > 1)
{
mon[1].Enabled = true;
mon[1].Primary = true;
TextBox.Text += "Monitor 2 Primary\n";
}
}
}
}

You're missing the call to the System object's ApplyMonitorChanges method, adding that to the click event handlers should fix the problem:
<![CDATA[sys.ApplyMonitorChanges();]]>
