At a guess you could use either brush type to flood fill a circle, then overpaint an inner circle in the background colour. That would give you the basic ring shape. You need to do some experimentation to figure out the optimum methods. Use the best guess

My be. But my main problem is create the component class. You know, in C#, i just reference the com dll. If i have to use the raw com dll file as common unmanaged dll, im not sure how to create the object and how to translate parameters. So, I hope to add referenct it via its type library(.tlb file).

I ALSO WANT TO KNOW..

I meant, how to use WM_MEASUREITEM and WM_DRAWITEM messages handler if i subclass its edit, button and listbox.

Hi... i dont have any network problem but still i'm not able to connect to MS SQL Server which is in another system of my LAN.... Please provide me what to chect wit SQl server and Connection string... pLZZZZZZZZ.......

Make sure you can connect with odbcad32.exe before trying your code. Then visit connectionstrings.com for help.

Thanks for your reply. I have tried this method but fail, because i always use the right idl files generated by atl project wizards, and i failed because i spelt 'Interface IB' other than 'interface IB'.(VS also highlights 'Interface' and 'interface'!). Regards.

oh, i forgot to say, this method still can't start the exe server in background

Im sorry, its my fault, i had declared two such controls, but unsubclssed only one. its ok now. Regards.

Cool. It really works. Before post this question, I only know atl only register the component's AppID and clsid, so it would not work if i remove the type library information from the resource. I want to write my own code to register the interfaces by hand before. Now, i know i only just modify a parameter in the existent code. Thanks very much. Regards.

OK. Its very kind of you.

Don't bother. A quick look through kilt's post history shows that his suggestions are all but completely useless. "Old age is like a bank account.

I really have that book, and i had read it twice, in fact. I will study harder to do that work. Thank you. Regards.

installing a windows update package with impapiv2, all problems will disappear.

oh, thanks for your reply. im reading the book named Inside COM. i hope i will resolve this problem when i learn further. regards.

yes. I wanna make the target program do nothing when the user click its right mouse key on the tray icon.

im sorry to reply so latter. i have gone to another city. and i know them problem now, i got the right menu, menuitems and menuIDs, but sent the menu message to a wrong hwnd. The program has more than one toplevel hwnd, so, i retieve all its top level hwnds and send menu message it them. then, when i got the right hwnd, the message would send successfully.
