.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))

VS 2010 Append Print Documents?

Jan 29, 2012

The three forms in my project have the ability to print in PrintDocument1.Print event. Each print-document consists of only one page in landscape shape and everything works fine. But it seems a bit clumsy to print three times with three buttons. I know, I can use the PerformClick event, but I wonder if there is a simple way to append all three documents into one by clilking only one button in my last form?

VS 2010 DataSet Append Write?

Mar 4, 2011

I am using a dataset control on a form to store and read data from XML files. So far I use the following to write info.

VB
Dim drow As Data.DataRow = DataSet1.Tables("item").NewRow
drow("path") = strFilePath
drow("id") = strCreationDate

[Code]..

The problem is I need to APPEND data to the same file. What I do now results in the same file being overwritten. I am dealing with large amounts of data, so I would love a way to append to the file without the need to re-read it with each save.code lines 1-4 are in a loop so that at one time, they add a few hundred rows to the DataSet. After that loop is when the save takes place. However, I want to run that loop again and again every so often to update that same file.

VS 2010 - Append New Line To Text File

Aug 28, 2011

I am trying to append a new line to a text file. Sometimes it posts to a new line (like I want it to) and sometimes it appends to the current line, consequently screwing up my read. I even put VbNewLine in the code.

Here is the snippet:
Dim outputline2 As String
outputline2 = equip & "," & value
Dim myfile2 = File.AppendText("equiped.txt")
myfile2.WriteLine(outputline2, vbNewLine)
myfile2.Close()

VS 2010 Compiler Creates New Variable Automatically When Use If Statement Without Strictly Declared Variable?

Jan 10, 2011

Say that i have the following code that parse about 20k records from the DB.

Code #1

vb.net While reader.Read()
list.Add(If(Integer.TryParse(reader(0).ToString, 0), Integer.Parse(reader(0).ToString), 0))
End While

And then another code which does the very same thing but it seems to be a little cleaner.

Code #2

vb.net While reader.Read()
Dim storeowner As Integer = 0
Integer.TryParse(reader(0).ToString, storeowner)
list.Add(storeowner)
End While

This is what i am confused about; does the compiler creates a new variable automatically when i use the if statement without strictly declared variable? What approach is better in sense of performance?

I have created a class with a public sub which has a variable with it using byval:
Public Class clsMessenger
Public Sub Messenger(ByVal Port As Integer)
End Sub
End Class

I now need to start that sub in a new thread and pass a varible to it but I am not entirly sure how to go about that. At the moment I have:
Dim ClientConnection As New clsMessenger
Dim ClientThread As New Threading.Thread(AddressOf ClientConnection.Messenger)
ClientThread.Start()

I can't use a global variable because there is going to be multiple instances of this routine running on different threads and each time the variable to be passed will be different.

VS 2010 : Dynamically Dimension A Variable?

May 5, 2010

is it possible to dynamically dimension a variable?in my case, i have a chart that has a varying number of series on it depending on the data extracted and in order to use those series, i have to dimension them manually before adding points to them, IE:

Dim series1 as New Series()
Dim series2 as New Series()
etc
etc

my series data is contained in a datatable, so i'll know the count required, but it will change at runtime, so obviously doing something like this won't work, but explains what i'm trying to do:

dim recordcount as integer = datatable.rows.count
for i = 1 to recordcount
dim "series"+recordcount.tostring as new series()
