Re: CoCreateInstance funny resturn value Nish Nishant20-Oct-01 0:40 Nish Nishant 20-Oct-01 0:40  Hi Norm I did that and got this E_NOINTERFACE Nish Re: CoCreateInstance funny resturn value NormDroid20-Oct-01 0:51 NormDroid 20-Oct-01 0:51  Is object properly registered, have you execeed the method count (check your IDL)? Normski - Professional Windows Programmer Re: CoCreateInstance funny resturn value Nish Nishant20-Oct-01 1:03 Nish Nishant 20-Oct-01 1:03  actually its a simple container com server was trying out how to create a container com server I created it as an exe I guess that might be the whole trouble I put a mesg box in the oevr-ridden FinalConstruct()and am getting it okay Thus I know its registered and I also know its getting called but some other error by the way when I manually tried to register it using regsvr32 I got an error. apparently you are not supposed to do that. am quite new to COM and am dead-stuck! I tried to call the same container server from VB and got some VB error message saying the component doesnot have an exposed interface or some such stuff maybe I did something wrong with the app wizard options there are too many options and I must have selected one wrong radio button or hit the wrong chk box... Nish Re: CoCreateInstance funny resturn value Nish Nishant20-Oct-01 1:18 Nish Nishant 20-Oct-01 1:18  prolly containing servers are a bad idea waaaaaaaaaaaaaaaaaah Nish Re: CoCreateInstance funny resturn value NormDroid20-Oct-01 2:59 NormDroid 20-Oct-01 2:59  Whats the application do? Normski - Professional Windows Programmer Re: CoCreateInstance funny resturn value Bill Wilson23-Oct-01 7:21 Bill Wilson 23-Oct-01 7:21  The error code you got when you tried to register manually, is describing what you have done wrong in your implementation. Placing COM objects inside a .EXE is creating what is called a Full Server. This is a common technique and works quite well. I sounds like the problem is in the component iteself. Pay attention to the error returned from the manual registration attempt. Hope this helps, Bill IWebBrowser2->ExecMB(...) problem IGx8919-Oct-01 8:34 IGx89 19-Oct-01 8:34  Sorry to bother you guys yet another time , but I keep getting a stack overflow whenever I call this line: g_pThis->m_spWebBrowser2->ExecWB(OLECMDID_NEW,OLECMDEXECOPT_DODEFAULT,Var1,Var2); I thought I was doing everything right, but I guess not... Re: IWebBrowser2->ExecMB(...) problem IGx8919-Oct-01 10:53 IGx89 19-Oct-01 10:53  Ok, I think the problem is that there is more than one item under the File->New menu. Is there any way that I could call the New->Window submenu? Possibly with a value in Var1? If there isn't, does anyone know an easy way to open a new IE window, which my ATL object could control? Re: IWebBrowser2->ExecMB(...) problem Bret Faller19-Oct-01 12:13 Bret Faller 19-Oct-01 12:13  You can use the Navigate2 function and pass the flag navOpenInNewWindow and use about:blank for the URL.

Please help me with some complete code samples which I can execute. Also please give some reference to COM resources using C++ on Internet. Thanks in advance. Nilotpal Nilotpal Re: Urgent Help on COM Firoz19-Oct-01 4:22 Firoz 19-Oct-01 4:22  Hi, There are some good samples of COM using C++ in MSDN. Same you may get from MSDN online... I think Inside-COM by Dale Rogerson is a good book...(in C++) for beginners.

I can create instance of object A in object C, no problems, object A can create object B, still no problems, BUT there's no way for me to force the object B to pass the Open method of ADO's Connection, i'm still geting 0x80004005 - Unspecified error. Is there anybody there who could help me, i would really appreaciate that. thanks a lot in advance johny flash update Johny Flash19-Oct-01 1:17 Johny Flash 19-Oct-01 1:17  definitely i'm not able to use even directly(without my objects descibed in the message above) ADO(COM) from executable service created with ATL COM AppWizard. Still can't open the connection, method Connection::Open Re: exe service using com which uses ADO:) Rashid Thadha20-Oct-01 12:56 Rashid Thadha 20-Oct-01 12:56  I have got ADO working in my NT Service without any problem. Are you calling ::CoInitialize and CoUnitialize in all your threads. You need to load the OLe libraries in all your threads. ADO requires this as it is a COM Object.

It did exactly what I wanted it to do . Adding a progress bar in ATL scoob18-Oct-01 7:53 scoob 18-Oct-01 7:53  Hi! I developped a MMC snapin that display an ATL object in the result pane (the one to the right). The ATL object is a Composite Control. The control is showing ok but there is no functionnality except the buttons. I would like to add a progress bar but it doesnt work. If anyone knows how to add the progress bar and make it functionnal. Or even better, if anyone knows how to use a CDialog (or anything CWnd based) based class behind that ATL object in the result pane. Help would be very appreciated! Thanks Scoob Interfacing w/ IE, andIOleControl IGx8917-Oct-01 15:49 IGx89 17-Oct-01 15:49  My goal: to be able to stop (and start, and stop again, etc...) left- and right-click events from going to Internet Explorer, AND to be able to send left- and right-click events to IE. My situation: I've already made a toolbar for IE, and am trying to implement the above in this toolbar. My efforts: I found the FreezeEvents method of IOleControl; would that work for part of what I want to do? If so, how do I implement it? I've gone crazy trying to figure out how to call the FreezeEvents function! Also remember, I still need to know how to send those mouse click events to IE. Help would be much appreciated! Re: Interfacing w/ IE, andIOleControl Erik Thompson18-Oct-01 8:29 Erik Thompson 18-Oct-01 8:29  Attache to the events of IE. You will get BeforeNavigate and such. then to simulate them youjust call Navigate2, Refresh, or Stop on the IWebBrowser2 interface. Also they have get_busy to tell if it is currently navigating/refreshing. Cheers, -Erik ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ My thoughts are my own and reflect on no other. Re: Interfacing w/ IE, andIOleControl IGx8918-Oct-01 12:56 IGx89 18-Oct-01 12:56  Uhhh, those things wouldn't help me a bit, I'm afraid Re-read my message, and you'll see what I mean. Basically, I just need to disable all right- and left-mouse button clicks, within the web site pane of Internet Explorer (disabling it within all of IE would work, too). Please help! I'll be able to make a killer helper for IE, if I can just get that figured out . Re: Interfacing w/ IE, andIOleControl IGx8919-Oct-01 5:43 IGx89 19-Oct-01 5:43  NM, I figured out how to do it! I just created a MouseProc hook, and returned -1.
