I'll give it a try in the morning (10.20PM in Singapore now) and post my test results. I'll run UltraVNC Server under a debuger and check if it processes the Windows key correctly.

I have tested this viewer issue with RealVNC server and UltraVNC server, it displays the same problem on both. Hope this info helps. M

I also figured a work around to my problem, which was to create short cuts on the desktop and assign them Shortcut keys such as CTRL+ALT_Num2, if I press the keys on the keyboard it works perfectly, if I used SendCustomKeyEx as below, nothing happens.Its definitely seems to be a problem with the function. Me.vwr_Main.SendCustomKeyEx(KeySym_Control_L, True)
Me.vwr_Main.SendCustomKeyEx(KeySym_Alt_L, True)
Me.vwr_Main.SendCustomKeyEx(Keys.NumPad2, True)
Me.vwr_Main.SendCustomKeyEx(Keys.NumPad2, False)
Me.vwr_Main.SendCustomKeyEx(KeySym_Alt_L, False)
Me.vwr_Main.SendCustomKeyEx(KeySym_Control_L, False)
Thanks M

Bad news....it looks like a VNC server doesn't process Windows key events. Look at the file attached. If you familiar with C++ you will see that their key map processing class works only with scan codes defined in the static keymap_t keymap[] array plus ordinary Latin-1 characters. The Windows key is not defined in the array. Look at the method void keyEvent(CARD32 keysym, bool down, vncServer *server) Line:254, the main processing logic is implemented by this method. Probably if you add scan code for the Windows key to the keymap array and recompile VNC server sources you will get it working. Unfortunately there is noting can be done about the problem on the ViewerX side, since this is a missing VNC server feature we are dealing here.

My browser failed, so I am not sure if you got this post or not.If the server doesnt process the windows key, why does the following code cause the windows start menu to open? Me.vwr_Main.SendCustomKeyEx(KeySym_Windows_L, True)Me.vwr_Main.SendCustomKeyEx(KeySym_Windows_L, false) Also why doesnt CTRL+ALT+Key work? Me.vwr_Main.SendCustomKeyEx(KeySym_Control_L, True)Me.vwr_Main.SendCustomKeyEx(KeySym_Alt_L, True)Me.vwr_Main.SendCustomKeyEx(Keys.NumPad3, True)Me.vwr_Main.SendCustomKeyEx(Keys.NumPad3, False)Me.vwr_Main.SendCustomKeyEx(KeySym_Alt_L, False)Me.vwr_Main.SendCustomKeyEx(KeySym_Control_L, False) This code doesnt launch the shortcut with this keyboard shortcut setup, but if I physically press the keys it does. Thanks M

I got it working! Apparently TightVNC server (which I was using for testing) doesn't support Windows key, but UltraVNC server does.
The trick is order in which scan codes are sent. The following works for me and opens the Run window:vx.SendCustomKeyEx(65515, true);
System.Threading.Thread.Sleep(100);
vx.SendCustomKeyEx(65515, false);
System.Threading.Thread.Sleep(100);
vx.SendCustomKeyEx(0x052, false);
System.Threading.Thread.Sleep(100);
vx.SendCustomKeyEx(0x052, true); Now you might be wondering what those Sleep(100) are doing the code. At least in my case, without them I was getting some random results; in some case the start menu would open and in some cases the Run window. Adding the Sleep call seems to fix the issue.
