ATL Web Service Question xizuo8-Jul-04 18:22 xizuo 8-Jul-04 18:22  I created a simple ATL web service with VC++ 7.1 by following the sample in MSDN and put it in IIS 5.1 on my local PC. But the web service doesn't work. If I tried to access it through IE, it either displayed "not found" page, or asked me to save the DLL itself on my PC. The same error occurred when I created an ATL web service client and tried to access the web service. Could any one help me with this issue? Thanks.

Paul M Watt6-Jul-04 20:59 Paul M Watt 6-Jul-04 20:59  HAve you added a property map entry in this thing: BEGIN_PROP_MAP(CYourControl) PROP_DATA_ENTRY("_cx", m_sizeExtent.cx, VT_UI4) PROP_DATA_ENTRY("_cy", m_sizeExtent.cy, VT_UI4) PROP_ENTRY("HREF", 0, CLSID_NULL) ... END_PROP_MAP() Your control will not know what to do with that param tag unless you have specified your property in this map.

Re: atl activex - property not being set, help! rusko7-Jul-04 4:27 rusko 7-Jul-04 4:27  yep, have it there and still no dice. ----- BEGIN_PROP_MAP(CMyClass) PROP_DATA_ENTRY("_cx", m_sizeExtent.cx, VT_UI4) PROP_DATA_ENTRY("_cy", m_sizeExtent.cy, VT_UI4) PROP_DATA_ENTRY("fileName", m_fileName, VT_BSTR) PROP_ENTRY("AutoSize", DISPID_AUTOSIZE, CLSID_NULL) // Example entries // PROP_ENTRY("Property Description", dispid, clsid) // PROP_PAGE(CLSID_StockColorPage) END_PROP_MAP() ----- also, how would setting the property *through script* work and through <param> not work if this were missing? thanks for your help though, any more ideas? paul Re: atl activex - property not being set, help! Michael Dunn7-Jul-04 10:15 Michael Dunn 7-Jul-04 10:15  <param> tags don't call property setters, your control has to implement IPersistPropertyBag and read the values using that interface. ATL has a IPersistPropertyBagImpl class to do much of the work for you. --Mike-- Personal stuff:: Ericahist | Homepage Shareware stuff:: 1ClickPicGrabber | RightClick-Encrypt CP stuff:: CP SearchBar v2.0.2 | C++ Forum FAQ ---- Re: atl activex - property not being set, help! rusko7-Jul-04 10:38 rusko 7-Jul-04 10:38  thank you! i'll go implement that and report back with the (hopefully positive) result. now *why* have i not been able to find any mention of this while RTFMing? aargh =] paul Re: atl activex - property not being set, help! rusko7-Jul-04 14:35 rusko 7-Jul-04 14:35  ok, this worked (somewhat). the plan was to grab the properties i'm interested in from the propertybag and call the property setters (which in turn call the property setters for the controls i'm hosting). the problem is that neither the hosted controls' nor even my window exist at this point. i got around this by setting a timer, calling the property setters in the timer callback and checking IsWindow() in the property setters. this works fine, albeit at the expense of messy code (some global variable nastiness). is there a better way of doing this? paul Help Me... atlctrls.h Compile Error... mssi6-Jul-04 1:43 mssi 6-Jul-04 1:43  Sample...

Having look through the commctrl.h header, it doesn't appear to be a factor. But then Microsoft Headers aren't the best layed out in the world. I may have a play when I'm on a machine with WTL installed, but I've not had this problem in the past. Michael CP Blog [^] Re: Help Me... atlctrls.h Compile Error... _oti15-Jul-04 12:50 _oti 15-Jul-04 12:50  The problem is (obviously) that ImageList_Read and ImageList_Write are not defined. The reason they're not defined because __IStream_INTERFACE_DEFINED__ is not defined. This is not defined because ObjIdl.h is not included. ObjIdl.h contains definitions for IStream, which is what the ImageLists are serialised to/from. There may be some issues with the point at which you include the file, and you may have to a #undef _INC_WINDOWS at some point. There are foggy wisps of memory regarding this, but I'm not sure if it applies to this problem. Hope this helps,     Phil -- All things considered, you can't really consider all things ...

Michael P Butler6-Jul-04 2:08 Michael P Butler 6-Jul-04 2:08  You'll need to create a seperate CDialogImpl derived class for each dialog and then call them using the DoModal function, or hide the current window and show the new dialog. Michael CP Blog [^] How do I implement an interface in ATL Field Zhang3-Jul-04 23:15 Field Zhang 3-Jul-04 23:15  Please help me. Let's say we have an COM interface IAppInterface from another application named App. What I want to do is to create my COM class and implements the IAppInterface. So I created a new ATL project MyObject, added a simple ATL object, and chose "Implement interface" from the menu. But after building this project, I cannot see IAppInterface from MyObject. What's wrong? I know I should do some thing in the .idl file. What should I do? By the way, I'm using Visual Studio .NET 2003. Thanks. import new type in ATL server Anonymous30-Jun-04 5:36 Anonymous 30-Jun-04 5:36  Hi, I would need a small help. I have developed a static C++ library, in which a class APDU is defined. Now I am developing an in-process server ATL whose class of implementation will have to contain as variable member an object APDU. Accordingly I would like, that the interfaces (what I am creating with the wizard) they accepted as parameter an object APDU. EXAMPLE (We suppose that my server ATL has to print the content of an APDU) I create my server ATL (step 1)File--> New--> Project--> ATL COM App Wizard--> project name=server (step 2) Server Type=DLL I insert a new object ATL Insert--> New ATL Object--> Simple Object--> Short Name = example To this point I want to add a type APDU property to the file idl Right mouse button-->Add Property How do I do to make APDU appear the type in the curtain menu that show the possible types??

You don't. Just type your type. All you have to make sure is that the IDL compiler recognizes your type. May or may not be easy. -- Ich bin Joachim von Hassel, und ich bin Pilot der Bundeswehr. Welle: Erdball - F104-G Starfighter BSTR returns invalid characters when multiple event sinks are used Aby Philip28-Jun-04 20:06 Aby Philip 28-Jun-04 20:06  Hi I have a component implementing a proprietary protocol (say, Protocol.dll)and does the communciation over serial port. I have defined ATL objects for each type of packet, and nearly all has a property called "description" which returns a BSTR. One ATL object encapsulates the serial communication. So I can set the baud rate, port number etc. A connection point event is defined corresponding to each packet that may arrive to the PC (from the device). Say ProtocolPkt1, ProtocolPkt2, ProtocolPkt3 etc. Now we typically use 2 serial ports. One that does proper protocol communciation and another that dumps trace staements. To take care of the trace statements I have one event defined (LogData) in the same event interface described above. I have an application (say Mainwindow.exe) that uses the above component, connects to both the ports and has separate event sinks to handle the 2 ports separately. The protocol data and the log data coming from the 2 ports are to be shown in separate windows. Whenever an event notifies that log data is received it is simply dumped in a window. Whenever any event notifying any of the protocol packets is received, the corresponding packet is created from the bytes received in the event, interpreted and displayed. Now onto the problem. When some protocol packets are received, the description property has to be called. When both the ports are connected the log data comes fine. But when the description property of say ProtocolPkt1 event is called, the BSTR returned is prefixed with some log string that came in the LogData event. Further the application displays a crash when it is closed. Some more observations. 1. This does not happen when the BSTR returned is very short. Typically only when the string returned is long and computed in some for loop, does this corruption occur. 2. This does not happen when I use the debug version of Protocol.dll. I hope I have made myself clear. If any information is required please let me know. Any pointers that can help me proceed would be greatly appreaciated Thanks aby Re: BSTR returns invalid characters when multiple event sinks are used palbano29-Jun-04 13:53 palbano 29-Jun-04 13:53  >> 2. This does not happen when I use the debug version of Protocol.dll. Have you tried looking at this article Surviving the Release Version? "No matter where you go, there your are." - Buckaroo Banzai -pete Re: BSTR returns invalid characters when multiple event sinks are used vprashu1-Jul-04 9:05 vprashu 1-Jul-04 9:05  Make sure that the code that fires the event manages the life time of the BSTR. I suspect that the first client is releasing the BSTR and hence ur second client sees garbage. For events and BSTR the caller allocates and frees the bstr. if u are using _bstr_t always pass a copy to the event( bstrVar.copy()) Hope this helps.. prashu
