Does m_IPtr have a valid value? What values does CreateInstance() return?

My code looks like this:

if( SUCCEEDED( hres = m_IPtr.CreateInstance("MyDll.Stuff") ) )// Create intstance to component<br />
{<br />
*_teststream << "handle to connection open - hres (S_OK) = " << ITOA(hres) << endl;<br />
}<br />
<br />
LPVOID lpMsgBuf;<br />
<br />
FormatMessage( FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM,<br />
 NULL, hres, MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),	(LPTSTR) &lpMsgBuf, 0, NULL);<br />
	<br />
*_out << endl <<  "DEBUG INFO: HRESULT = " << (char*)lpMsgBuf;<br />
<br />
delete lpMsgBuf;<br />

And the output on the failing cpus is:

DEBUG INFO: HRESULT = Ogiltig klassträng
"invalid classtring" (or something in english)

Does "MyDll.Stuff" exist under the HKEY_CLASSES_ROOT registry key?

Are you saying this is a release only problem? Or that it only happens on a non-development machine?

Um, If you use Depends.exe it will list the libraries that MyDLL.dll uses. Are they the same on both systems?

I think that your registry is corrupted. Try to use any tool to verify. You can find over internet these tools. Smile | :)

But, you can do it manulay.
- Verify if the class Id are the same.
- Backup your registry (Its corrupted, but just save)
- If are, look in registry for the all class Id and Interface Id for the Dll (Realy realy hard work), and delete All.
- Delete all temporary files (sometimes its works)
- Shutdown your system
- Try to install new DLL
- Registry new dll, recompile your program (Rebuild All)
- If not works, you have serious problem, may be, you should format your PC Frown | :(

- Registry your dll
- Look in registry for your DLL Name (MyDll.Dll)
- Try to search any entry like this {5EFCDACB-46BD-4904-B8AF-4DD75D5C0144}
- This is an example of GUIID Smile | :)

Its hard work .....

If you do it very well with attention, probably, you will get a success.

Does the registration work? i.e. are there any errors reported back from regsvr32?

We have a task creating a Scheduled Task in a Remote Machine. For this we are using the ITaskScheduler interface. Using this we are creating a Scheduled task which is working fine in the local machine. But when getting connected to the remote machine using the ITaskScheduler::SetTargetComputer() it is failing returning the error AccessDenied...

Please help if any possible solutions let us know...

If any clarifications feel free to ask..

Per MSDN:

The current user on the remote computer must have administrative access to use this method. For more information on remote installation requirements, refer to Mstask.hlp.

dialog based + creating file associations?

Allman8-Jun-04 1:19

8-Jun-04 1:19

Hi, I'm using Visual c++ and I've done a program where I've defined my own file format. I would like to be able to create file associations with my program with these type of files...lets say *.qif .

Anyone has any ideas how I could do this, so that when I click on a *.qif file, my program would load and on startup would load the specific *.qif file?

I'm not using a SDI or MDI. The program is dialog based, and the file format was generated from an edit box.

Thanks for any suggestions..

Re: dialog based + creating file associations?

David Crow8-Jun-04 2:31

Re: dialog based + creating file associations?

8-Jun-04 2:31

You can do the same thing that an SDI or MDI application does, call RegisterShellFileTypes().

Re: dialog based + creating file associations?

8-Jun-04 2:35

You need to write appropriate registry entries into the registry.

In the HKEY_CLASSES_ROOT, add the appropriate data excluding quotes

1) Add a key called ".qif"
2) Under .qif set the (Default) string value to "QifFile"
3) Add a key called "QifFile"
4) Under QifFile add a key called "shell"
5) Under shell add a key called "open"
6) Under open add a key called "command"
7) Under command set the (Default) string value to the commandline parameters of your application.

And basically thats that. Smile | :)

For #1 - Its very strange, verify if the user that you are using to start the windows service have the privilegies. Show your code. Confused | :confused:

#2 - Try to use Hook Mechanism. The KeyBD_Event does not work with Windows Service, because The windows Service does not get messages from KeyBoard. You should use Hook ... Look for Hook in Code Project, that you will find your information. Smile | :)
