I have a DWORD value 1619.

Corresponding error message to this value is :
"This installation package could not be opened. verify that the package exists and that you
can access it, or contact the application vendor to verify that this is a valid windows installer
package"

Is there a way (an API) which I could use to get the error message (as a string) by providing the DWORD value ?

Thanks in advance

i have an application where i have to connect 3 deivce on TCP/IP. I would receive data from any of the device when it requested from the PC.

Could any one help me on how to proceed about this requirement. I read few literature on Multi threading but i am not sure how to implement multithreading in VC++.

Yes, I can.

SO what is the problem now? Didn't you understand the mechanism for multithreading ie how to start the threads and keep on collecting data for each one of them.
Have you started to write some code and can you show it?

You need to google first, if you have "It's urgent please" mentioned in your question.

Hello all,
I have a doubt here:
If i have three socket connections does it make it necessary to have them in 3 separate threads(to ensure concurrent reception of data from all three)? Or is it that since the OnReceive() functions of the respective socket class are independent events that are all capable of getting triggered at the same time (as perceived by the application), thus, can exist under one single thread?

Timers in Windows

Hi friends,
I'm researching on Timers in Windows and I've read "Timers Tutorial" in codeproject from this link:
"http://www.codeproject.com/KB/system/timers_intro.aspx" but I would like to know:
Do we have any timer with the nanosecond precision or no?

Thanks in advance

I don't think nanosecond precession is possible with windows timers. But i believe with multimedia timers nanosecond precession is possible.

No, and anyway Windows is not a real-time operating system so you can't achieve that precision. I'm afraid you'll need to switch to a real-time operating system and I'm even not sure that you'll be able to reach that precision.

I think Yes! please check QueryPerformanceCounter
