.Net And VS 2010 Append A Variable To An URL?

Apr 16, 2012

I'm a newbie writing my first app. I need help with the following: I need to retrieve the logged in user which = GID, I then need to append it to a URL which will start our Help Desk chat client. I can retrieve the GID easy enough but can't figure out how to append it and pass it with the URL. I found a post which instructed to declare the url as a string also and concatenate it. The UserName would follow the ":" at the end of the Url.

[Code]...

We use javascript to do this from the HelpDesk site, but I need to adapt it to work from my app.

VS 2008 - Append Now Time Part To Date Variable

Jan 11, 2010

I'm working on a small accounting app. I have a query to show transactions with a running balance.

SELECT transactionid, transactiondatetime,
amount,
(SELECT SUM(amount)
FROM dbo.transactions as D1
WHERE D1.transactiondatetime <= D0.transactiondatetime) AS balance
FROM dbo.transactions AS D0

I capture a gamesheet for a certain week. so if I select a date on a monthcalendar the sheet applies to the weeknumber of the selected date. When I save transactions I take the date at the last day of that week as the transactiondate. I need to store a datetime though because my query works of the datetime to get an accurate running balance. How can I append now() time part to my date variable and then store that in a datetime variable to get a transactiondatetime.

Here is my code for getting a transactiondate:
Dim dt As New Date
dt = Me.MonthCalendar1.SelectionStart
'get last date of week. Friday
Dim tdate As Date = dt.AddDays(5 - CInt(dt.DayOfWeek))

Use The ToString Method And A Counter To Concatenate A File Name Into A String Variable From The Image.FromFile Method?

Dec 18, 2010

I have nine pictures that I need to animate -I need to use the ToString method and a counter to concatenate a file name into a string variable from the Image.FromFile method. Once the counter reaches its maximum value, and the last picture is displayed, the counter should be reset to zero or one depending on how the first image file has been name. Also a static counter variable should be incremented in the time routine. what I have so far -- I know what I have to do; however, I just do not know how to code this properly.. Right now I have this going thru a button procedure but it needs to go through a timer.

VS 2008 For Loop Through Results?

I can't think of a better way to do this, what i have is this function:

vb.net

which usually contains: 4 so when i loop out the names, it loops the 4 results, 4 times, instead of just showing me the names 4 times so i can then store them

VS 2010 Loop Through The Results Of Capture Group Regex Query?

Apr 29, 2012

I'm trying to find a way where i can make it loop through the results of my capture group regex query.

For instance if i have this:

VB.NET
Dim matches = Regex.Matches("<h1><span>test</span></h1>", "(?<=<h1>(<span>)?)(?<data>.+)(?=(</span>)?</h1>)")For Each item In matches.OfType(Of Match)()Console.WriteLine(item.Value)Next

And i'm trying to get the contents of <data>, how do i do it without it printing out the junk before it and after it?

quantifier isn't working, its supposed to make the <span> tag optional in the query, but it isn't.

.net - Windows API Leads To Different Results Based On Name Of Unused Variable?

Apr 5, 2012

Everything I know about .Net programming tells me that the behavior I see here is completely impossible. Simple code:

Structure WKSTA_USER_INFO_1
Dim wkui1_username As Integer
Dim wkui1_logon_domain As Integer

[Code]....

When I put a break point in here, I see that after RtlMoveMemory, my wk1 contains a pointer to a username, and all the others are 0. This is consistant. Now, if I change Dim test As String = "" to Dim login As String = "" and run it again, wk1 contains pointers to both username and logon_domain.

If I change it to Dim login As String, it contains a pointer to only the username. Depending on what I change that (completely unused) variable name to, I get a different result.

I have always been under the impression that it cannot possibly matter what you choose to name your variable. And that declaring a variable, and then never using it, cannot possible be different from not having a variable there at all.

I've tried this on 2 computers, with consistant results (one on .Net 3.5 and one on 4.0). When I tried converting it to C#, however, I was not able to reproduce it.

I am aware, by the way, that I can just use System.Environment to get what I need about the current user information; this was old VB6 code that was automatically upgraded (and I've edited it a little to make it more trivial).

Loop While Application Is Running?

Nov 19, 2009

I am writing a program that is connected to an rs232 port and I need it to constantly be monitoring the incoming data. I think there are a few ways of doing this like checking the buffer but I need this to be running while I am connected to the port. I have a play button and a pause button for the port. When the play button is pressed, the port is open and the button is no longer enabled until the pause button is pressed. I need to have a while loop running the entire time the play button is no enabled, or pressed. I am having a hard time knowing where to implement it in the code.

Running A Loop When A Button Is Pressed?

Sep 30, 2011

I'm developing a interface in VB.net which will control two stepper motors. Counting on your tips I managed to control them manually I mean, there're 4 buttons used to move the motors clockwise and anti-clockwise. The point is, the main part of our project is control the motors automatically. Our idea is based on two editable fields, X and Y, where the user would insert the displacement value he'd like the motor to move. After filling up both fields, the "GO" buttons would be pressed. So the loop would run depending on the displacement values in X and Y.

Attached you can find the main screen:

Below you can find the main code.

Dim velocidade As Double = 0.004

VS 2010 : Use Controls While A Loop Is Running?

Oct 4, 2011

Basically what I have are two loops, one inside the other, that will run until the given condition is met. Exactly what I want. My problem is that I want to be able to use the controls, like buttons, while a loop is going on.

I originally did not think of this until I had built this part of my program, what I want to know is if there is a way to use controls while a loop is going on or if their is an alternative.

1)I know timers can be used to meet these goals, but they did not work out as I had hoped and using two timers (1 to represent each loop) I do not believe is efficient.

2)I have considered using recursion, but have found this may not be very efficient either and am not quite sure if this will do what I want.

These loops run as long as the number the user inputted. So it could theoretically run for 100,000+ times. I am not looking for speed, but it would be good if there were a faster method that allowed me to use controls while it loops.

Textbox Text Not Updating While For Each Loop Running?

Mar 8, 2012

Windows Forms, VB application... Forgive me in advance for this very elementary question but I am overlooking something really simple here. I would like to have a label show the current value of a variable as the for each loop runs.. I created a very simple Button Click event to figure out where its failing. As it is right now the value does not display until after the for each loop finishes running, which it should actually display the counter value each time it runs through... I know this is possible and really simple because I did it years back but for the life of me cant figure out why I am missing the bar as it should constantly update the label to reflect that?Test Sub is as follows:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim counter As Integer = 0
For x As Integer = 1 To 200000

While Loop - When Running The Debug The Program Crashes

Mar 15, 2012

I've been having a bit of a problem using the while function.

Here is my code (Simplified):
Dim RandomNumber3 As Random
Dim RandomOutput3 As Integer

[CODE]..............

When running the debug, the program crashes, and when I step into the program, I find that this While statement becomes an infinite loop. This is a program that uses random number generators to assign a value to something, and this while statement is necessary so that there is never two of the same values showing (RandomOutput, RandomOutput2 & RandomOutput) Have to be different to one another.
