ATL ActiveX Control - Window Creation 23-Feb-01 3:36 23-Feb-01 3:36  Hello, I am creating an ActiveX control using ATL to replace an existing one based on MFC - it all works fine in test container. I have a problem when putting the control onto a HTML page. The previous control loaded a file in the onload handler in javascript: e.g. function myloader() { myobject.loadfile("wibble.file"); } etc. the onload code needs a valid window to have been created - the problem is that the window is not created until after the method is called. I have the m_bWindowOnly set to true so it should be trying to create a windowless control. anyone else come across this or know how to overcome it. Thanks Building MFC COM Connectable Objects 21-Feb-01 2:21 21-Feb-01 2:21  How do I built a connectable component using MFC? The component should be capable of sending and receiving events. Thanks, Can't use a handle to object 18-Feb-01 8:49 18-Feb-01 8:49  When I pass a handle of file (or bitmap) to the server ,which has been opened from the client , the server can't access the file.When the server reads from the file , the operation don't return an error code but the information that has been read is wrong(or the bitmap can't be selected in any device context).I tried lots of things , but nothing helped me.Please help me. Re: Can't use a handle to object Julien28-Feb-01 16:55 Julien 28-Feb-01 16:55  hey Joe, You can not use HANDLE's between processes. You need to call DuplicateHandle to have your second process have its own handle to the same resource. Watch out for the first arguement to DuplicateHandle as it is a HANDLE to the process that created it, the way to get that is to call OpenProcess with the ProcessId.

Do you guys know anything about how to do that and kindly give me some ideas?

So you will have an internal transparent rectangle inside A black rectangle. Does anyone knows how to make an ActiveX control that has a transparent rectangle inside it ?

Problems registering DLL 12-Feb-01 7:23 12-Feb-01 7:23  I'm writing a COM Application using ATL. Up until now, I haven't had a problem with building the DLL. I was debugging my application and made a minor change to solve a problem. But I couldn't register my DLL. I undid my change but I still get the following error: Linking... Creating library Debug/MAPConnector.lib and object Debug/MAPConnector.exp Performing registration RegSvr32: LoadLibrary(".\Debug\MAPConnector.dll") failed. GetLastError returns 0x000000c1. MAPConnector.dll - 0 error(s), 0 warning(s) Could someone tell me what the error message means and how to solve it? I'll appreciate any help I can get. Re: Problems registering DLL Chris Losinger12-Feb-01 7:33 Chris Losinger 12-Feb-01 7:33  0x000000c1 = "%1 is not a valid Windows NT application." try Tools / Error Lookup in VC. -c Re: Problems registering DLL Blake Miller12-Feb-01 8:21 Blake Miller 12-Feb-01 8:21  -- RegSvr32: LoadLibrary(".\Debug\MAPConnector.dll") failed. ".\Debug\MAPConnector.dll" is a relative path name. Maybe some other DLL used by your application is not in the path at the time RegSvr32 is being executed. Or else the current directory is not in the correct location relative to your path for RegSvr32 to find your DLL to load it to register it at the time you are doing the build. I seem to recall editing the project build settings and using a variable that represent the project directory, instead of an abolute relative path to the DLL. for exmaple "$(ProjDir)\Debug\MAPConnector.dll" IRotView source astibich12-Feb-01 6:31 astibich 12-Feb-01 6:31  Does anyone know where to find the source it IRotView, the MSDEV tool for viewing the contents of the running object table? Actually I'd be happy with any rot view app. Thanks, Aaron Re: IRotView source pba_11-Apr-01 1:50 pba_ 11-Apr-01 1:50  You can you own IRotView app. very easy. Use COM API function GetRunningObjectTable, from where you will have a pointer to a IRunningObjectTable interface. After that you could enumerate the running objects using EnumRunning.

Unexpected return from DoDragDrop Steve Thresher9-Feb-01 6:09 Steve Thresher 9-Feb-01 6:09  I have a C function that calls a C++ function that calls DoDragDrop() to drag a file using the CF_HDROP format data object. The global memory is moveable. Under any NT version of Windows this returns the expected value DROPEFFECT_COPY but under Win9x the function returns RPC_E_SERVERFAULT. I can only get the drag operation to work under Win9x if I use fixed global memory. Does anyone have any suggestions as to what is going on? ATL and Connection Points 9-Feb-01 1:09 9-Feb-01 1:09  Hi, I Created a COM object(Client) which is to be connected to a COM exe( server ). Below is the piece of code i am executing.......
