What 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 don't want it to start off at 0. I don't want there to be any text in Label1 and Label2 at the start of the program.
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 5 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
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.
View 5 Repliescame across this issue while converting a for loop in C# to VB.net I realized that the increment operators are not available in vb.net (++ and --)whereas i was able it do something like cnt +=1 .In VB, a STATEMENT cannot be just an EXPRESSION. why this doesn't work in the same way as it does in C#.

I have constructed my database and I have used auto increment the ID's of each column. When I was testing and inserting data into my tables the auto increment of these column's of course incremented.
Now I am looking to start each individual Id column at 1 and not at the number where it is now.
I know it has something to do with using max value and +1. I have deleted the entire table and have tried everything to re-insert my data and start the ID's at 1, but I have had no luck.
Also to,
I know within Vb I can use a datagrid view and add there and it starts at the max value of the column +1, but when I have another form to add data within columns the column number is not in numerical order, How do include code within that seperate form to auto increment ID column numerically?

View 2 RepliesCan a VB.NET For loop be constructed that mimics this C# code?
TimeSpan oneDay = TimeSpan.FromDays(1.0);
for (DateTime d = startDate; d < endDate; d += oneDay) {
// some code

Obviously you could do it without a For loop (i.e., with a While); I'm just curious if there's a certain syntax to construct a VB.NET For loop with a non-integer increment that I'm not aware of.
There are 3 columns(Count,Item,Price) in datagridview which is bound to a datasource. The count is 1 by default and it should increment by 1 when i click on a button,so the count would be 2 if i click button again
View 1 RepliesI am using the AJAXToolkit Accordion control and dynamically adding panes to it based on a query of the database. For example:
Jane logs in and pulls up the page with the accordion on it. In the database she has five rows in the todo_list table. So, I need to dynamically generate five panes that contain the info. from the table...but if Joe logs in he may have only three rows, and Josh may have fifteen - so I can never know how many an individual will have beforehand.
So, I need some way to dynamically name the variables (or is there another way to do this). For example, here is some pseudo-code of what I'm trying to accomplish:
Dim i as integer
For each row in todo_list
Dim ap + i as New AccordionPane
Add some info from the row to the pane

I have a database containing usernames and "points". I need to increment the "points" at will. I have the table connected to a sqldatasource.
Here is my current code:
With Users
.UpdateCommand = "UPDATE Users SET points = points + 1"
.Update()
End With
This works great, except, instead of just changing the entry with the username specified by a QueryString, it changes all of the entries and adds one.The sqldatasource has the following select command:
SelectCommand="SELECT * FROM [Users] WHERE ([username] = @username)"
This command makes it so that only entries with the querystring specified username are displayed. This is really my first attempt at SQL.
