Task manager does not show most of the process

 Well, i was doing some coding in vb.net and a line was like this:

SetLocaleInfo(LOCALE_USER_DEFAULT, &HE, ".")

to set a new decimal separator. (don't ask why)

But there was an exception when i was trying the code.  

In the end the problem ocurred when it let the decimal separator in blank.  You would think that does not care, but it does to me.  

My ArcGis software stop working. It was showing an error message syaing the default database .gdb was corrupted.  Also the task manager in windows 10 does not show most of the process.  

It took me a while to find the error, but in the end I resolve it just by stablishing the dot as a decimal separator in
