ControlPaint.DrawReversibleLine works fine. A whole new class I didn't know about. Thanks to all.:)

I don't think so. The MSDDN doesn't state that you need the presence of a real DNS in your Network and i successfully used this method in my local LAN to determine whether a PC can be reached or not. www.troschuetz.de

The TabPage does not include the tab itself; that is painted and otherwise handled by the TabControl. With that in mind and looking at the TabControl events, you should notice the SelectedIndexChanged event. This posting is provided "AS IS" with no warranties, and confers no rights.

Heh, I faced the same problem once. Turns out the icon in the systray can only have the 16 primary colours. You will need to be really creative with those 16 colours if you want your icons to look good. This limitation is not there in XP though.

The DataGrid does not allow you to draw the column headers. I would recommend a third-party control like XtraGrid from Developer Express[^] if you require such functionality.

:doh: Of course, I need to 'OpenSubKey()' with write permission. Anyway, could you confirn that the 'CurrentControlSet' is the correct key, and not 'ControlSet001' or 'ControlSet003'. What are these? Having got the service working as I want it, I now cannot stop it programatically. System.ServiceProcess.ServiceController sc = new System.ServiceProcess.ServiceController("SpyFive"); try { sc.Stop(); } catch { .... there is nothing caught, the service goes into 'stopping' mode and then nothing can be done with it (even from MMC). Any ideas?

chris fearnley wrote: The procs are working now anyway. Excellent. I have actually thought of another possible solution. It may be possible to have a combined primary key on your tables, the extra field for the primary key would be the based on the serial number you mention above. If this is too much repetition of data (I'm guessing the serial numbers are quite long) you can set up a lookup table that contains all the relevant serial numbers and use its primary key in the main (original) table. For example: +----+--------------+ | PK | SerialId | | | SerialNumber | +----+--------------+ | | /|\ +--------+----------------+ | PK, FK | SerialId | | PK | OriginalId | | | OriginalField1 | | | OriginalField2 | +--------+----------------+ With this schema your stored procedures would only need to add an extra item to the where clause to get the same effect has lots of tables with identical schema. chris fearnley wrote: If your SQL experience covers security issues, and you know what "21CFRpart11" is, I could do with your help on a paid basis Unfortunately my knowledge of Security is about average for a developer (in other words: quite limited), although I am due to go on some courses later this year.

I did read your reply but didn't know that HitTest could be used for anything other than a mouse position - that's what the help for HitTest suggests. But I'm still not getting there... DataGrid.HitTestInfo hti = valueGrid.HitTest(1,1); int row = hti.Row; if (row >=0) {....... but row always gives -1 no matter where the scroll position is. I've also tried DataGrid.HitTestInfo hti = valueGrid.HitTest(valueGrid.Location); but no joy, and even tried checking the point in the middle of the top left cell, but again always row = -1. Obviously I'm missing something very obvious!:confused:

It's happened on two machines (while running this app) and the machines have been fine at other times. Not much in common with them otherwise except both have XP pro and VS .NET loaded. They're different makes and they're not even in the same building! Not using any interop services, only the Win32 serial port code as suggested by the JH:Combase class [DllImport("kernel32.dll", SetLastError=true)] internal static extern IntPtr CreateFile(String lpFileName........ etc... which I think I got from CodeProject but can't find now. Thanks for suggestions so far anyway.

Search this site to find lots of example. You can first create a Bitmap object and assign it to Graphics object, then draw whatever you want to it. This will works I think. Mazy "A bank is a place that will lend you money if you can prove that you don't need it." - Bob Hope
