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

How do I get the class Id?
I've used Dependecy Walker and there all seems Ok.

- 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
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..
Thanks

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.

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..

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

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.

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

What user account is the service running under? It seems that you either need to alter the account that the service is running under or you need to alter the account privileges.

I try to create a dynamic char-array and then copy a certain number of chars from another string to it:
<br />
char *tempLabel = new char[labelLen];
strncpy(tempLabel, label, labelLen);
When I step through the code the variables contains:
After line 1:
label = "resolutionXììììììììì....aso" (is an [128]-array)
tempLabel = "ìììììììììììýýýý" (as you see, 4 chars too much)
labelLen= 11;
After line 2:
label = "resolutionXììììììììì....aso"
tempLabel = "resolutionXýýýý" (Still too big!)
labelLen= 11;
Why??? I don't want those 'ý'-s, what's wrong? Does anyone have a clue?
|
|
|
|
|
if(labelLen>0)
{
char *tempLabel = new char[labelLen+1]; //Line 1 make room for \0
strncpy(tempLabel, label, labelLen); //Line 2
}
Papa
while (TRUE)
Papa.WillLove ( Bebe ) ;
|
|
|
|
|
Try this:
char *tempLabel = new char[labelLen]; //your Line 1
memset(tempLabel, (int)'\0', labelLen);
strcpy(tempLabel, label); //Line 2

This is exactly how buffer overruns are exploited (i.e., using strcpy).
