.net - Memoryusage Drops After A Week?
May 18, 2011
I have this app written in VB.Net with winforms that shows some stats and pictures on a bigscreen monitor.I also monitor the memory usage of sad app by using this. Process.WorkingSet64
I know windows does not always report the correct usage but I just wanted to know if I didn't have any little memory leaks which I had but are solved now. But the first week the memory usage was around 100MB and the second week the memory usage showed around 50MB.
So why did it all of a sudden drop while still running the exact same code?I can hardly imagine that the garbage collector kicked in this late since the app refreshes every 10 seconds and it has ample time in between those periods to do it's thing.Or perhaps there is just better way to get memory usage for a process that is more reliable.

I need to generate a report that shows the 52 weeks of a year (or 53 weeks as some years have) and their start and end dates. There is an ISO spec to do this but seems awfully complicated! Im hoping someone knows of a way to do it in C# or Visual Basic (its actually for Visual Basic 6 but I will try port it across)

In regular SQL i could do something like
SELECT * From T GROUP BY DATEPART(wk, T.Date)
How can i do that in Linq to SQL ?
The following don't work
From F In DB.T Group R By DatePart(DateInterval.WeekOfYear, F.Date)
Also don't work:
From F In DB.T Group R By (F.Date.DayOfYear / 7)

I have written a application that has a TCP client and server to connect to a PLC. The Client works perfectly but it looks like the server drops out all the time. What happens is when I first start the connection it will update without any problems but after about 1min of no transfer the PLC can no longer send data to the application. Neither system gives an error and the PLC shows that it is transmitting the data but nothing comes through on the application side of things. I have tried to put in heartbeat to see if that would stop the drop out but to no avail.[code]

I've been using some code which I found on the net, and have noticed that the first byte is never recieved. Annoyingly, this contains the MAC addresses, which is the bit I want. Below is the relevant snippits:

I can't see anything in the method list that lets you know when a connection drops (and since it's constantly checking, it seems that could have been in there, to raise a flag when it can't find the connection anymore...no?). Is there a way to know if the network connection drops? Is there a way to reconnect it? Is it just a matter of turning EnableRaisingEvents() off and back on to re-establish the link to the network share?

I have 3 lists in my form.When 1 list is clicked, I want to drop the selection in the other 2 lists.
Private Sub lstPlaylist_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstPlaylist.SelectedIndexChanged
lstArtist.ClearSelected()[code]....
This is my current code. When I click on lstPlaylist, it drops the selection for all lists.

Several times while debugging a VB.Net program I have found that continuation lines are missing from a subroutine designed to handle an event. The continuation character "_" is there but the following line is missing
[Code]...
The first few times I figured I had made some editing error, but this has happened 3 times now, always in the same way (different subroutines but same place). As far as I can tell, no other continuation lines have changed. Is this a bug or some feature I have missed?

I am writing some code as part of a framework for opening a file.The file is of custom type and should not be opened by more than one instance of my application. To stop multiple file opening I use a filestream to create a lock file and then keep said filestream open. This seems to work in preventing another instance of my application from opening the file ( as it will fail in recreating the lock stream in the files open code ) but if the file is on a network share and the network drops then the original application also can not access the file any more.The code to get the lock stream is as follows:
Try
' We need to keep this stream alive to prevent other applications gaining access to the lock
mLockStream = New FileStream(mLockPath, FileMode.CreateNew, FileAccess.Write, FileShare.None)[code]....
In this I create the lock stream the first time round and then if another application tries to create it, it throws an exception and stops them from getting any further. This is kind of how it needs to work, unfortunately as I said, if this is done across a network and then the network connection is dropped for some reason then I can not delete the lock stream as I get an IOException telling me a process cannot access the file as it is open in another process ( which shouldn't be happening I don't think).

Sorry in advance. I emailed myself my coding since I don't have vb on my personal computer. Sooo, the format is going to be off. But my program allows the computer to generate a random date. The user has to guess what day of the week the random date lands on. I have written the whole code. It all works except when user checks his/her answer. The answer always comes up as incorrect. Here is the coding:

I have a ComboBox where I select which day of the week I want it to update. And each week at that day, at a predefined time as well I want it to add 1 to an integer. I want it to continue doing this until I stop it. When I close the program I want it to do a check on start up if it has past that set date and time, if it has it should add 1 to the integer again, if 2 weeks have past I want it to add 2 to the integer.

Ok so i'm working on this project that requires me to imput a month and year which then will output the number of days in the selected month for you to select from, then determines what day of the week it is. The problem i'm having is that I cant get the month to the converted value that I need for it to work . Example: January will be the 13th month and february as the 14th of the previous year. Heres what i have so far if it helps. Aslo the code that I have to use to find the day of the week only works when the total is divided by 7, and then the value of the remainder is the day of the week with saturday =0, sunday=1, monday=2, and so on.
