Make Loop In Program And Calculate Time Taken To Complete Loop?
Nov 23, 2011I am constructing a program, i am new to Visual Basic, but i have past programming experience. I was wondering if anyone knew how to form a loop that could...lets say calculate the answer when two numbers are added together,and it would repeat this thousands of times, etc. And if there is a way, would it be possible to calculate the time taken to complete this loop.

Aug 14, 2009I've converted a VB6 application with the VS 2008 built-in feature successfully: upgraded some bits of code, added new features, built, tested, and run the compiled application on my development laptop successfully. Then I created a SETUP.EXE for it with the appropriate VS 2008 tool, and test that successfully on my development laptop. Then I gave the setup.exe & xxx.msi to my client and the installation went fine. So far so good.

May 28, 2009Is there any way to loop through the applications that run at a time (the application list from task manager) and get the application's caption?
At a moment I have two instances of "acad.exe" but they will have different application name and I have to choose one of them, but I don't want to close the other one.
If I use the process list I get only the "acad.exe" name and I cannot differentiate between them.
VS 2008 Loop Through A Second Time?
Sep 2, 2009The code below finds a string from a text file and, if the correct month, - Monthcheck1, adds it as an item to an unsorted ListBox. I want to run through the text file again to find data for the next month. If I repeat this code for MonthCheck2, nothing is added. My question is: What is the convention for looping through the same file a second or third time?

Run Time Error During Long Loop?
Dec 7, 2011I wrote a program which loops through a very long CSV file (50 meg) and parses the data as it goes.Sometimes, the program aborts and I get the following message:The CLR has been unable to transition from COM context 0x37a090 to COM context 0x37a200 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.
I know its going to take a while. There are several hundred thousand lines of text in the file that this program is reading. I am not sure exacly waht the message means, but my program seems to work fine other than the message. odd thing is sometimes the message doesnt always pop up..
VB Loop And Display One Line At A Time?
Jan 20, 2010I'm using visual studios 2008, VB9 and I am trying to write an app that basically performs calculations on a set of data input by a user. During the calculations, I want to display the data at each step, and have it retained in the display area on the GUI (not overwritten by the next data being displayed).
For example:
UserInput = 1
Do
UserInput += 1
[Code]....
I tried this, and other loop structures and can't seem to get things right. The actual app is a bit more sophisticated, but the example serves well for logical purposes.
Get An In A Loop To Accept A Value And Add It To A List Each-time Okay Is Pressed?
Dec 9, 2011I'm trying to get an in a loop to accept a value and add it to a list each time okay is pressed. For some reason, I have to add a value twice for the input to be added to the list. For example, if i enter the string "hello" in the inputbox and click okay, it doesn't add to the list, but if i do it a second time, it goes in.
Here is the code for it
Do Until lstCourse.Items.Count = CDbl(txtClasses.Text)
InputBox("Enter Course Number", "Course Number")
strCourse = InputBox("Enter Course Number", "Course Number")
lstCourse.Items.Add(strCourse)

Loop - Sub - Wrote Only To Temporarily Fill The Database In During Run Time
May 1, 2009I have a sub that i wrote only to temporarily fill the database in during run time to be able to test a few other functions that i wrote as well ... weird thing is by the way i wrote it it should only look 100 times... but by the unique ID in the database and the information it pulls back into my list box it loops 700 times before actually stopping the loop ...
Public Sub Fill_LeftOvers()
Dim x As Integer = 0
conn.Open()
[CODE]...
Now i used step debugging and sure enough it only loops 100 times during stepping but in the database it looped like crazy ... i have also tried while x < 100 instead of the do loop but it did the same thing ... i know this may be considered a double post i mistakenly posted originally in the PHP forums earlier today ...
Using For Loop Counter In VB To Change Variables Being Referenced Each Time

The data submits to an SQL database. All the radio buttons are similarly named, so only the number changes for the question [Code]

Loop Computation Time Increases Dramatically With Small Change
Apr 3, 2012I recently made a change to the code within a loop in my code, and now when I run the code through Visual Studio 2010 Express, the loop runs about 10x slower than the previous loop.I did not make any significant changes (to my knowledge) to the code within the loop.I made the change so that the loop could handle various conditions I imposed in another section of the code.I know that it is this loop that is slowing everything down because I report the loop progress on my form.[code]I feel like my changed code should run better, but it doesn't.I know that my code is not written very efficiently (and feel free to comment on ways to improve it), but my main concern is the significant increase in computation time that resulted from my changes.The loop above is the main block of code within the Sub, which is run via a thread.In my tests, it is the only thread running at that time.Everything works, and the computation yields the correct result, but takes 10x longer than previously. Additionally, the number of iterations does not increase.So the new code isn't iterating excessively, it is simply taking much longer to compute within each iteration.
View 19 RepliesVariable Declared Inside A For Loop - Make This To A Compile Time Error?
Mar 27, 2012Today I investigated a logical bug in our software and figured out that this is related to the way VB.NET thread variables inside a loop.Let's say I have the following code:
Dim numbers As New List(Of Integer) From {1, 2, 3, 4, 5}
For Each number As Integer In numbers
Dim isEven As Boolean
[code]....
The problem is that isEven is declared but not assigned.In this specific case, it would be correct to write dim isEven as Boolean = false but I haven't done this.In VB.NET, a variable that is declared inside a for loop keeps its value for the next itaration. This is by design: [URL]but this is also dangerous pitfall for programmers.
However, until now, I haven't been aware of this problem/behaviour. Until now.Most of our code base is C# anyway, which doesn't allow the use of an uninitialized variable, so there is no problem. But we have some legacy code that is written in VB.NET that we have to support. So the best thing would be to generate a warning or even an error in this specific case.But even with Option Explicit / Option Strict this does not generate a warning / an error.Is there a way make this a compile time error or maybe a way to check this with FxCop?

VS 2005 - Print The Entire Datarow At A Time And Then Loop Through All The Rows Present In The Datatable?
Mar 26, 2010I have created a datatable and now i need to print it,so i did the following:
Private Sub PrintDocument1_PrintPage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage
Dim xPos As Single = 20
[CODE]...
The code works fine.But in the above code as you can see that i am printing the each rows content of the datatable one by one and after printing all the contents of a single row i am looping the code again for printing each and every row present in the datatable. So i want to know that inspite of printing each and every data present in the row of the datatable,is it possible to print the entire datarow at a time and then loop through all the rows present in the datatable?

View 4 RepliesEvaluates Loop Condition In Do...Loop Statment To Determine Whether Loop Instructions Should Be Processed
Mar 14, 2011Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

GC Free The Memory Associated To The Arrays "in Time" For The Next Loop ?
Jul 19, 2011I have a system that must do massive array operations. Often I have many arrays with 1 to 2 million elements at same time.
Usually I create the arrays inside a procedure, so, I expect when the array variable goes out of scope, the array becomes available to the GC. But in the near future, I'll need to do these operations in a "looping" way, so I'll create and delete the arrays many times...
Will GC free the memory associated to the arrays "in time" for the next loop or it is best to "force" it in someway, like using the erase statement? Or maybe I'm completely wrong?
C# - Convert A Date And Time To UTC Time Based On The Time Zone Of The User?
Sep 6, 2009I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).
I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?
