View 4 RepliesVB 2005 - Sync Lock In Multithreaded Programs
May 16, 2010I have been reading through lots of sample code and explainations regaurding the uses of Sync lock in multithreaded programs but still am a little fuzzy on this.
Am I correct in assuming that if I have two or more threads running the same procedure which has a sync lock on a shared resource that the first thread to call the lock will complete its update of the resource and any of the other threads to try and lock this object would just wait in line until it is released by the first object?
I am also a bit fuzzy on what is actually locked by the sync lock.
Lets say I have code that uses sync lock and the object specified is the current thread. Does that also lock the shared resources that are referenced within the sync lock block or would I need to use another method to do this?
What if my shared resourses were all in another class and I issue a sync lock on that class before I try to modify the resources would that be the proper way to go about it?
And last but not least is there any need to use sync lock when the shared resource is in effect read only [meaning the program will read the value but will not change it during runtime]

Lock Records On SQL?
Sep 25, 2009I have a form and its filled from a VIEW of two tables on SQL server. When its opened i dont want other users opening that customers details from either table.I know SQL itself prevents writes if its opened but i want to stop people opening the record in the first place.[code]...
I then tried writing these values to the db on the form loading but it doesent work - it just sends back NULLs. I tried the same code in the on load event into a button and it works fine there. So im thinking i should do this as a Trigger on SQL itself, but im unsure how i could get the users computername or Windows Login name, or even username from the front end im building.
Lock XML File When In Use?
Dec 6, 2006I am using XML files to store some iformation that are to be processed. I use this code to interact with the XML file:
Dim xmlDoc As New XmlDocumentxmlDoc.Load("theXMLFile")
Do XML stuff such as add elements...
xmlDoc.DocumentElement.AppendChild(oAlarm)xmlDoc.Save("theXMLFile")
What I want to do is to lock the file so that no other process can use the file. If a process wants to use the file, I also want it to wait and try again until file is available.
