View 6 RepliesLINQ Short-circuit Evaluation In .NET?
Jan 5, 2012We had a Nullable object must have a value error today on this line of code:list = From x In Me Where x.FooDate.HasValue AndAlso x.FooDate.Value.Date >= barDate
Funny thing is that I feel sure this used to work fine (and there has always been a sprinkling of null values in the underlying data). And logically it looks fine to me. The check for HasValue and the AndAlso look as if they're going to shield us from any Null danger.But it seems suddenly they're not. Am I missing something?OK, we can correct it to this, which eliminates the error:
list = From x In Me Where If(x.FooDate.HasValue, x.FooDate.Value.Date >= barDate,False)
But this looks to me less readable. In simplifying the above code to shorten the line I left out a crucial chunk of the code. The original problem should have read something like:
list = From x In Me Where x.FooDate.HasValue AndAlso x.FooDate.Value.Date >= fromDate And x.FooDate.Value.Date <= toDate
Because of the rules of shortcircuiting and operator precedence (as outlined in an answer to a long ago question of my own) I needed to add brackets round the second part of the instruction in order to stop LINQ evaluating the second x.FooDate.Value.Date:
list = From x In Me Where x.FooDate.HasValue AndAlso (x.FooDate.Value.Date >= fromDate and x.FooDate.Value.Date <= toDate) LINQ really does obey AndAlso and force me to look more closely at the original problem.

Stopping Multiple Timers - Stop Button To Stop Each Timer One At A Time
Feb 26, 2009Alright, so I'm still working on the slot machine. I have three timers all independently going for my three "wheels" of the slot machine.
My issue, is that I'm trying to make a Stop button to stop each timer one at a time, and I'm not understanding why this code isn't working. The logic completely makes sense, and the first "wheel" stops when I click the button, however, it doesnt appear to stop the other two timers.

VS 2010 : Use A Stop Button To Stop A Loop?
Dec 7, 2009I created a form and have the variable inputs for 4 motor run statements. Then with a start button the script starts and it is surrounded by a for next statement to loop 10 times. It works fine but if i need to stop the execution of the script with a stop button. I put the stop in a new section but of course does not work to do a motor stop. It just causes the exe to not respond till the loop is complete. Just need to be able to stop the Run1_Click button section.
Edit:I do not mind if it finishes the 4 motor run commands and then stops execution of the loop. So need to figure out a way to trigger a stop from a button on the form to stop the cycle. For the future the loop will be a variable integer input so 10 will not be the standard.
Edit::Does a ' Do ' statement sound like the thing to use? If so how and where would I place that? Have a Stop button on the form and it would stop after the 4th motor run command.

VS 2010 Stop A Block Of Code Executing When User Clicks "Stop"?
Mar 1, 2011I have a START and STOP button and when the user clicks "start" the program does a whole bunch of calculations and all. However, I noticed that when I was testing the program I clicked STOP the program continues to execute stuff.
My START code is basically a while loop that iteratively does some calculations.
So I just put a boolean variable as the while condition and when user clicks stop its set to false and when user clicks start its set to true. However, when I click stop, the condition is set to false yes but it still executes all the code until the condition is re-evaluated right...so my question is how can I get out of the while loop when user instantly clicks "stop"?

.net - Stop Asp.net Looking For Assemblies In GAC?
Sep 20, 2011I have started working on a legacy project (ASP.NET 1.1) which was done in an old machine (which I dont have access to). And I am unaware of the development environment settings used for building this project.
Nonetheless, I am able to build the project and deploy it all well from my machine (I created the full development enviroment locally). In my machine everything works great.But some screens where one of the assembly dlls (third party dlls) are used do crash on any machine other than mine! They probably do net get the proper assembly (with matching version or something), even though when I have put all the assemblies in bin (and used the same files while adding references to the project). .NET runtime probably tries to find them in the GAC of the other computers? Or probably in my system itself it loads from GAC and not from the bin? How could I know all this? The question is it runs perfectly fine on my machine, where the assemblies are at both places - in bin and in GAC.
I am lost what I should do to so that no matter which machine I deploy the project, it should always look in bin only! Also, I dont want to change the code in any way because its a legacy code and has been working all right since ages! Just some settings e.g. maching.config or soemthing?
