Did you create all the registry entries for your COM Server? When you add a reference to the .dll, VB reads the .dll and accesses it directly. When you use CreateObject(ObjectID), COM looks up the ObjectID in the registry to get its GUID and then looks up the GUID in the registry to find your .dll and its type library. To be able to use CreateObject(), there are several registry entries needed. Your library is MY.dll, so let's call the typelib MY.tlb. These are the minimum entries you need: HKEY_CLASSES_ROOT\\MYLib.MyApis = "My COM Server" _(Friendly name)_ HKEY_CLASSES_ROOT\\MYLib.MyApis\\CLSID = GUID_of_Class_MyApis HKEY_CLASSES_ROOT\\CLSID\\GUID_of_Class_MyApis = "My COM Server" _(Friendly name)_ HKEY_CLASSES_ROOT\\CLSID\\GUID_of_Class_MyApis\\InProcServer32 = "[PATH]\MY.dll" ThreadingModel = "Apartment" (This one is a value under InProcServer32, not a key) HKEY_CLASSES_ROOT\\CLSID\\GUID_of_Class_MyApis\\ProgID = "MYLib.MyApis" HKEY_CLASSES_ROOT\\CLSID\\GUID_of_Class_MyApis\\TypeLib = GUID_of_TypeLib HKEY_CLASSES_ROOT\\CLSID\\GUID_of_Class_MyApis\\Version = "1.0" HKEY_CLASSES_ROOT\\Interface\\GUID_of_Interface_IMyInterface = "My COM Interface" _(Friendly name)_ HKEY_CLASSES_ROOT\\Interface\\GUID_of_Interface_IMyInterface\\TypeLib = GUID_of_TypeLib HKEY_CLASSES_ROOT\\Interface\\GUID_of_Interface_IMyInterface\\Version = "1.0" HKEY_CLASSES_ROOT\\TypeLib\\GUID_of_TypeLib HKEY_CLASSES_ROOT\\TypeLib\\GUID_of_TypeLib\\1.0 = "My COM Server Type Library" _(Friendly name)_ HKEY_CLASSES_ROOT\\TypeLib\\GUID_of_TypeLib\\1.0\\0 HKEY_CLASSES_ROOT\\TypeLib\\GUID_of_TypeLib\\1.0\\0\\win32 = "[PATH]\MY.tlb" Technically there is a versioning issue here, so your \\GUID_of_Class_MyApis\\ProgID value should be "MYLib.MyApis.1" and then you'd create a VersionIndependentID key to associate "MYLib.MyApis" with "MYLib.MyApis.1"... but this isn't strictly necessary. Though you can create them by hand using RegEdit, all of these keys should be created in your DLL's DllRegisterServer() method and they should be deleted in your DLL's DllUnregisterServer() method, for use with RegSvr32.exe Hope this helps, MZR

thanks naveen vineesh

hi, try to learn how to program it as a Automation client and DCOM. you do not need the signature information about the COM server if you go by this way! ^-^ @|@ - redCat

Thanks for the reply. Actually i want to list out all the installed patches in the machine . I was able to list the patches to a specific product by msienumpatches() function .But i need to pass the product code to the function. The product code i was getting from msienumproducts() list out the registered product which will not list out the os . So i think i need to look some other way to handle this .. vineesh

provisioning simply means automatically installing and configuring operating systems, Suppose i have a server machine and some n number of computers connected to it . The server then done a mulitcast to all the members to know which machine is needed a O/S installation . The client machines which are waiting for installation will send back a request to the server . Then the server needs to install the O/S followed by the system softwares and appln softwares on to the respective machines . There are two different ways to achieve this one is a disk cloning second is a scripted installation Both disk cloning and unattended scripted installs can be performed remotely using a PXE/DHCP server. Now my question is whether we are bale to write some APIs for this remote installations ? Is it clear now ..? vineesh

you can use GetFileInformationByHandle typedef struct _BY_HANDLE_FILE_INFORMATION { DWORD dwFileAttributes; FILETIME ftCreationTime; FILETIME ftLastAccessTime; FILETIME ftLastWriteTime; DWORD dwVolumeSerialNumber; DWORD nFileSizeHigh; DWORD nFileSizeLow; DWORD nNumberOfLinks; DWORD nFileIndexHigh; DWORD nFileIndexLow; } BY_HANDLE_FILE_INFORMATION, *PBY_HANDLE_FILE_INFORMATION; modified on Friday, July 25, 2008 7:50 AM

I've just looked on MSDN for the command, and it looks fairly cleanly documented. http://msdn.microsoft.com/en-us/library/ms721790(VS.85).aspx[^] You pass it a couple of bits of information, it returns information which you tidy up with LsAFreeMemory. The hard bits would be generating the SID value, and the Policy object. But if you click on the link, it gives you a nice big example on how to get it. The below link goes to a page called "Translating between Names and SIDs", taken from the contents of the left of the MSDN site. http://msdn.microsoft.com/en-us/library/ms722463(VS.85).aspx[^] I hoped that helped you on your way, Iain. Plz sir... CPallini CPallini abuz drugz, plz plz help urgent.

And for what reason, might I ask, would you want to impersonate a user? Forgive me if your intentions are good, but this sounds like a question better asked at http://www.offensivecomputing.net/[^]

can you show us the code?

Thanks .. It works vineesh

Just read the file into an array of lines, and loop backwards to the first occurrence of the delimiter (exit 1), keep track of the index you found and go from there. Dybs
