All of the Windows core is native code, and its API functions can be accessed perfectly using P/Invoke.

That message is thrown when the method can't be found in the library. You might want to try to use the GetCurrentProcessorNumber method instead.

[DllImport("kernel32.dll", CharSet = CharSet.Auto)]
public static extern int GetCurrentProcessorNumber();

Hope this helps Smile | :)

Windows XP does not support this.

Dang, you're right - Vista and up. A quick Google found an alternative for XP;

Windows service using custom DLL

Building a windows service which needs to call a custom DLL. When I try to start the service it gives me an error stating it can't find the DLL. Which makes since since I was unable to register the DLL using Regsvr32. If I take out the DLL the service works fine (minus functionality of custom DLL). If I create a project with the same functionality as the service everything works fine once I add a reference to the DLL. Is there anything I can do to get the windows service to work with this custom DLL?

Only thing I have found is to add the DLL to the System32 direcotry which I have done.

Ever tried to get the current directory of your service? I think this will not be the directory
you are awaiting, normally its C:\Windows\system32 for services.
So if your dll is not in the C:\Windows\system32 directory you have to find out
where your service install path is.

For example:
Registry.GetValue("HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Services\\[yourservice_name]", "ImagePath", null);

Thanks Covean. As usual I amde it much more difficult than it needed to be. All I had to do was put the dll in the same directory as the file used to create the service. Thanks, you pointed me in the right direction.

Your question isn't very clear at all. I'm guessing you want to assign passwords to folders in the file system??

This requires writing a file system extension to NTFS. This is something that you cannot do in C#, only C++. On top of that, you also need to write a management app that manages the passwords and can reset them. Of course, you can't just let anyone reset the passwords either. Even that is going to need its own security. By the way, this is always something a newbie comes up with. Noone ever writes it when they find out how much work it really is to do.

Hi,

I have a text object on my crystal report. The text interpretation is "RTF text". Data in this text object appears in correct format except tables.

What is problem with table?

The CrystalReport RichTextBox doesn't support tables, and a bunch of other stuff.

You can read more about it here[^].

Use a monospaced font and create the tables using ASCII characters.

that is good solution, but I will take to much efforts. Actually I need some quick solution.

You're only other solution is to NOT use Crystal Reports and use some other reporting package.

Timer Control Not working in proper Interval + Sourabh Das

Hi Guys,
I have dragged and droped a timer control "tmrGetMappingXML" from the Common Controls Tab in Tool Box. The issue that I am mentioning also appears for the Timer Control present in the Components Tab in tool box.

In the form Load i have written:

tmrGetMappingXML.Interval = 3600; //1 Hour = 3600 Seconds
tmrGetMappingXML.Enabled = True;
tmrGetMappingXML.Start();

The timer interval is also set in the design time to 3600 seconds.

But the Tick event of the timer fires continuously every second. Fed up.

Please suggest.

Regards,
Sourabh

Thanks and Regards,
