Question Atomic Operations or checking file for lock

[rodgerwilco]

Hi there,

I would like to know if there is any opportunity in VB.Net to use atomic operations. Or Maybe there is an opportunity to check if a file is allready in use or opened.
The reason why I ask is because I got a little application that I would like to log its actions. As the applications uses threads the method for writing the log file sometimes is trying to open the log-file more than once which leads to an exception.
anyone got an idea how to solve this?

Put the code that accesses the file inside a SyncLock block. The body of the SyncLock block is a critical section, i.e. only one thread can execute it at a time.

Thank you for your answer. I will give it a try. But what about the second thread that is trying to access the file? Is this thread going to wait, till the first thread has left the block?

Look first, ask questions later. If you read the documentation for the SyncLock statement then your question will be answered.
