Multiple Referers One At A Time Loop Error ?
Jan 21, 2012
Here is the code:
CODE:
What I want to do is I want to post to different referers one at a time and of course the links will be provided by a richtextbox(i.e. richtextbox1.lines(i) ). I will use only password(which will be chosen by the user from a combobox(combobox1.text)) because the username is harcoded. This is what so far ive come up with but it always gives me the result of the first line(or referer) from richtextbox1. I think there might be a problem with my "FOR" code.

I 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..

Today 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?

I 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.

Is 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.

The 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?

I checked the contents of the array at the end and it only held the last records within the text file, which suggest that it is overwriting the array, how can i prevent this?

How can I loop through each date in a given time period so that I can add those dates as a column name in a table. I want to create datatable with the person's name and hours he worked in a given time period. The user will select the dates and I want to show each day/date in that table as a column name.

I'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.

I'm new to this, so sorry if my question has been asked before. I have searched but have not been able to find, or perhaps recognise, an answer. I am using visual studio 2008 and creating an app in vb.net.
I have 4 arrays named:- account1 account2 account3 account4. They all have 4 elements.I want to assign values to the elements in the arrays in an efficient manner. I thought two for next loops would do it. [code]....

I have a piece of code that loops through the rows in a database and brings out information.
The code is attached to a button(search). To search for data, you enter a phone number, the loop goes through the data rows and bring out the information is it is there.
Everything works great accept I have added a second table to the database.
So do I add a whole new loop statement? Example lets say I had a new data row, how can I add that to this statement so that both tables are searched?
This is the code:
Dim strGetRecord As String = masTxtPhoneField.Text
For validData = 0 To storedtData.Rows.Count - 1
If strGetRecord = storedData.Rows(validData)("fldphone").ToString Then

I'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

I am trying to loop through a dataset and process n numbers of records at a time.For example lets say I have around 240 records in my dataset. I need to loop through the dataset and then create a new batch of 50 records. so for the dataset which has 240 records I want to create 6 batches. Out of these 6 batches, 5 would have 50 records and and last batch would have 40 records.
