View 12 RepliesPattern For Limiting Number Of Simultaneous Asynchronous Calls?
Apr 9, 2010I need to retrieve multiple objects from an external system. The external system supports multiple simultaneous requests (i.e. threads), but it is possible to flood the external system - therefore I want to be able to retrieve multiple objects asynchronously, but I want to be able to throttle the number of simultaneous async requests. i.e. I need to retrieve 100 items, but don't want to be retrieving more than 25 of them at once. When each request of the 25 completes, I want to trigger another retrieval, and once they are all complete I want to return all of the results in the order they were requested (i.e. there is no point returning the results until the entire call is returned). Are there any recommended patterns for this sort of thing?

C# - LinqToSql - Prevent Sub Queries When Limiting Number Of Rows Returned?
Sep 16, 2009Dim query = (From p in Parent _
select _
p.ID, _
Tags = String.Join("|", p.Child.Select(Function(c) c.Tag.TagName).ToArray)).Take(100)
In the above query, when using Take to limit the rows returned, a separate SQL query is executed for each row to return the 'Tags' field. If I remove Take(100), a single query to sent to Sql Server.So, how do I limit the number of rows returned, while preventing a new sub query being executed for each row?

View 1 RepliesPrompt The User To Enter The Beginning Number And The Ending Number
Oct 4, 2009I am supposed to create a program in my VB.net class to do the following:
1. Prompt the user to enter the beginning number and the ending number.
2. Find the sum of the even numbers between these two values, inclusive.

We are currently using for next statements in the class. I know how to prompt for and utilize the numbers that are input etc. My problem is the EVEN numbers part. I obviously have to determine if the number is even and then use a step value of 2 from there. But not sure how to determine if number is even or odd (guessing to use mod, but totally lost).

View 4 RepliesHow To Enter Serial Number Into Registry
Feb 7, 2009I am trying to release my program now and I have a quick (hopefully quick) question concerning serial numbers. I want to be able to store the trial serial number so if the user uninstalls and reinstalls they won't get another evaluation period free of charge. My concern is that some crafty person will simply move the database files in and out of those installs and keep going indefinately. Although I have some protections built into the database itself in case the program runs out, I just want one extra layer of protection. Is there a way to store the serial number in the registry when entered and check for that entry whenever the program is installed using Windows Installer 3.1?

Apr 28, 2012So I wanted to make a program for math where you enter a number into a box. Then you click enter. The program has numbers 1-12 next to a check box. If you click enter it divides your number by the numbers 1-12. Let's say you put 100 in that box. Then you clicked enter. The check box next to ten would be checked, 4, 2, and 5 would all be checked because those numbers evenly go into 100. How can I have the vb check to see if the sum is a whole number?
