View 5 RepliesWhat code do I have to program to make this possible:
If Button1 is clicked, the number in Label1 increases by 1.
If Button2 is clicked, the number in Label2 increases by 1.

I have the following code
Protected Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAdd.Click
Dim counter As Integer = 0
Dim t As DataTable = DirectCast(Session("MyDataTable"), DataTable)
Dim row1 As DataRow = t.NewRow()
If (isUnique(t) And counter < 30) Then
row1("ID") = counter + 1

View 1 RepliesI have an SQL statement which i need to code in vb:
CODE:
Notice the fields prodno1 and prodno2 in the table structure.. this is part of a number of sql statements i need to run and put inside a loop. my problem is i want to automatically use this same code such that on the next loop, this sql statement is going to be:
CODE:
Note that in this "2nd loop"
- the table name is now r3 from r2 in the first SQL statement
- there are now prodno1, prodno2 and prodno3 instead of just prodno1 and prodno2
- in the WHERE clause, the p.prodNo becomes p.prodNo2
And so on and so forth.. so for the 3rd loop
- there's going to be r4
- there's going to be prodno4
- in the WHERE clause i will use p.prodNo3

View 3 RepliesHow do I increment a primary key that is in integer digit format to a record when adding or pressing an "Add New" button that I have on my form. In other words, I have a 'Add New' Button that has the code following:
[code]...
As you can see from the above code, that most of the textboxes are cleared so that a enduser can insert his or her values and information. Currently, I do have the OrderNumber which is the primary key cleared, however, I would rather have this field auto incremented to the next digit. For some reason, at the moment, I just do not know where to begin to set this field so that a digit canbe inserted and incremented rather than cleared.
Do we have increment operators in VB.Net? I want to use post increment and Pre increment operators in VB.Net.I want touse the statement like, i++ and ++i.

"Write a program that allows users to vote on their favorite singer American Idol style. Your program should have the following features:
Your program should use a single listbox to display the names of the contestants and the number of votes for each contestant.
Use a class to hold the contestant�s first name, last name, and number of votes. The class should include a method to increment the contestant�s vote count by 1. Be sure to use property procedures for the first name, last name and number of votes properties.
Your program should read the names of contestants from an input file and display them in the listbox. You cannot make assumptions about how many contestants there will be in advance.
Your program should allow the user to sort the contestants by the number of votes they got. It should also allow the user to vote for any contestant any time by entering the last name of the contestant."So far this is the only code that I have... not sure why nothing is working.

View 7 RepliesAt my old job we used batchscripts to start macro's in another application. These batch scripts would also write data about the status of the macro as loglines to a log file using VB.
I have saved the batchscripts when I moved to another job because I always thought they might come in handy. However I forgot to save the visual basic script needed to create and fill the logfile.
The batchscript would look like this:
SET SP=C: est
SET LOGFILE=C: est est.log
cscript //nologo %SP%logging.vbs "Script executed by admin" >%LOGFILE%
cscript //nologo %SP%logging.vbs "Starting Loading Data" >>%LOGFILE%

View 2 RepliesI am working on a function that returns an array of variable-length strings that have a certain starting and ending delimiter. The input to the function is a string. I am able to do this by using if-then statements with InStr(). I was wondering someone knew of a more elegant way. I tried using the split command but I am splitting on one delimiter so I don't really get the result. I could then parse from the results but I am back to the same boat with using InStr().

I have a script file which uses code similar to the C# language, using { and } braces to start and close 'blocks' of code. Note that blocks can be nested.[code]...
Is it possible to use regular expressions to parse the code and return the name of each block separately? So in the above example, it should return block1, block2 and block3 but NOT "block 2 contains" or "and another" (no nested blocks).
I am trying to replace the vb source code in our application by using a streamreader and a loop.

I thought this was a useful way to back up my project via email because it's in text form. But now I can't find the same information. I've looked in the Object Browser but couldn't find it anywhere.

So where will I find this mysterious page that has all the form items information in text, not graphic form? Can't find it anywhere.
