QuerInterface fails for an Interface of type IUnknown in VB .NET windows service but the same works in VB .NET forms application VM JOE9-Jul-09 3:51 VM JOE 9-Jul-09 3:51  Here is the IDL definition [                object,                uuid(DAFB7D76-0158-452F-8FD0-FF97A683DEA3),                      helpstring("ITest Interface"),                pointer_default(unique)       ]       interface ITest : IUnknown       {                [helpstring("method GetString")] HRESULT GetString([out,retval]   BSTR* pVal);       };       [       uuid(E768DC15-A19B-407C-ACF9-C420D6FDB1BE),       version(1.0),       helpstring("TestServer 1.0 Type Library") ] library TESTSERVERLib {       importlib("stdole32.tlb");       importlib("stdole2.tlb");       [                uuid(788571BD-030B-49CC-8C0A-2DF74E58331A),                helpstring("Test Class")       ]       coclass Test       {                [default] interface ITest;       }; }; The ATL COM Library uses APARTMENT threading model. And the VB.NET windows service code fragment                   try                            Dim obj As New TESTSERVERLib.Test                            Dim s As String                            s = obj.GetString()                   Catch ex As Exception                            WriteToLog(ex.Message)                            WriteToLog(ex.InnerException.ToString)                   End Try When the code executes the following error occurs: Unable to cast COM object of type 'TESTSERVERLib.TestClass' to interface type 'TESTSERVERLib.ITest'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{DAFB7D76-0158-452F-8FD0-FF97A683DEA3}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)). Object reference not set to an instance of an object. But the same code works in VB.NET forms application. Can anyone please explain the reason. Add extra device property sheet in Windows 7 Devices and Printers User 60869398-Jul-09 10:15 User 6086939 8-Jul-09 10:15  I am trying to add an extra property page to a device in Windows 7 Devices and Printers. I am following http://www.microsoft.com/whdc/device/DeviceExperience/DevPrintFolder-Ext.mspx and http://msdn.microsoft.com/en-us/library/cc144106(VS.85).aspx I can add a shortcut item to "right click" menu of the device successfully; however, the extra property page does not show open in device Properties window. If I follow the same steps to add the extra property page to a .test file type, it works and I can see the extra property page shows up. It seems that the COM dll for the property page is fine. Any one successfully completed similar things before? The following is what I added in Registry: HKEY_CLASSES_ROOT\CLSID\{Page 1 Property Sheet Handler CLSID GUID}\InProcServer32 (Default) = C:\MyDir\MySheet1.dll ThreadingModel = Apartment HKEY_CLASSES_ROOT\DeviceDisplayObject\HardwareId\Device hardware id\shellex\PropertySheetHandlers\MySheet1 (Default) = {Page1 Property Sheet Handler CLSID GUID} Button on Toolbar not showing chervon effect am 20097-Jul-09 0:24 am 2009 7-Jul-09 0:24  hello , Button on Toolbar not showing chervon effect.

SMPP COM library harrisyn6-Jul-09 13:27 harrisyn 6-Jul-09 13:27  Hi Guys, I have been searching for a SMPP lib for a while now, I finally stumbled on a dll, created by a Romzy, but there wasnt any samples or instructions for implementation, nor have I been able to trace the developer, I have tried using the DLL with little I could gather from the SMPP protocol definition, but in binding to a SMSC, it includes a Sendbindtranceiver with requires (index as short, hsocket as integer, SMPP_PDU_Bind_Transmitter), what I'd like to know is, anyone understand or can suggest what the index might mean or how that data type (short) can be represented and what does hsocket mean. I do understand that it may be impossible to understand without seeing the code, but I m snatching at straws right now. Any help or suggestions will be welcome. Re: SMPP COM library Md. Marufuzzaman6-Jul-09 21:49 Md. Marufuzzaman 6-Jul-09 21:49  Hi.. You are using a third party com or if you create your own api? Please let me know the detail. Thanks Md. Marufuzzaman Re: SMPP COM library harrisyn7-Jul-09 12:01 harrisyn 7-Jul-09 12:01  Hi, Thanks for the quick response. I am using a third party com dll, but cant seem to bind to the smsc. I will be grateful if you have a Smpp library preferably com, that I can use. Re: SMPP COM library Md. Marufuzzaman7-Jul-09 22:41 Md. Marufuzzaman 7-Jul-09 22:41  Well... You have 2 options (a) Create your own api, (b) Use third party api. let me know that you only send 160 char message or Hex like .. Wap push, logo, mono ring tone etc you also must get the smsc acknowledgment an Alphanumeric message submit ID right? Md. Marufuzzaman Re: SMPP COM library harrisyn7-Jul-09 23:07 harrisyn 7-Jul-09 23:07  Thanks Marufuzzaman, I am not knowledgeable enough to build my own API, unless I can get a push in the right direction or can get hold of manuals in that regard. I only need for it to send 160 char. to the receipient, no need for any acknowledgements or response from the receipient, just sending the message(s). Any idea I can use? Re: SMPP COM library Md. Marufuzzaman8-Jul-09 18:21 Md. Marufuzzaman 8-Jul-09 18:21  Hi harrisyn, So you will use a 3rd party api. Try the following: http://www.activexperts.com/xmstoolkit/ If you interested to create SMPP api, I think I can help you. Thanks Md. Marufuzzaman Md.

I know how to do it with a Browser-Extension but not how to do it with an ActiveX Control. I even can't find any example. Any help or tip would be great!

Re: IE8 Addons Icon Juergen2-Jul-09 2:01 Juergen 2-Jul-09 2:01  No I do not have a link to information saying it can be done but also no that it cannot be done. I supposed if the Control has a place for Icons, then there should be a way to display one for each element not only Browser-Extensions.

Re: IE8 Addons Icon myLongNic9-Jul-09 15:22 myLongNic 9-Jul-09 15:22  Could you please describe how to add icon in IE8 Manage-Addons-Dialog for the Browser-Extension? Re: IE8 Addons Icon Juergen10-Jul-09 0:19 Juergen 10-Jul-09 0:19  You have to add an registry-entry. Here is an example: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Extensions\{FB5F1910-F110-11d2-BB9E-00C04F795683}] "ButtonText"="Messenger" "CLSID"="{1FBA04EE-3024-11D2-8F1F-0000F87ABD16}" "Default Visible"="Yes" "Exec"="C:\\Programme\\Messenger\\msmsgs.exe" "HotIcon"="C:\\Programme\\Messenger\\msmsgs.exe,302" "Icon"="C:\\Programme\\Messenger\\msmsgs.exe,301" "MenuText"="Windows Messenger" "ToolTip"="Windows Messenger" HotIcon/Icon also could be a path to a "Image.ico"
