VS 2010 How To Get Sequence Number By Adding 1 To The Results Of A Count
Apr 18, 2012
I'm trying to write a function which obtains the sequence_number by counting the records in a table that fit a particular criteria and if the result is 0 or nothing sets a variable to 1 but if the result is 1 for instance, the variable will be set to 1 + 1.
This is the code i'm using but i'm not getting the correct result when results are actually returned. For instance, if the result of count is 1, i want "seq" to equal 1 and total (which represents the sequence # assigned to the next record which is entered with the same plan and date) would therefore be 2 which is the result of seq + 1 (i.e. 1 + 1)

Select Value, Count(Value) as Total
From DataTable
Group By Value
Order by Value ASC
I'm looking to return the following from the above example :-
Value Total
1 2

Would it be possible to list the number of items in a rich text box? Each item starts on a new line. Something like the following but obviously for a rtb.
TextBox1.Text = ListBox1.Items.Count

I am back as always! Here is my question. First and formally, With the code;
SendRequest("http://aavirtual.net/brett/core/classes/class.acars.php?fun=6")
Dim Splitter
Splitter = Split(request, ";")
With that data above, I am creating a For Statement to loop all the data being pulled, into a Rich text Box. Here is the question. I need to count the number of objects Splitted.
Example:
Car;
Train;
Boat;
Bike;
The Splitter is ";", And there are a total of 4 Objects needing to be split. How can i count the number of objects? The Objects are Car;Train;Boat;Bike, And I need visual basic to count the number of those objects which is 4. But I need a function that will output that.

designing a Windows based computer program that will allow a user to enter some number (n) and a choice of a count up or count down for that many numbers. So for example, the user enters 5 as their number and selects the count down option, the message box displayed would contain the message: "Here are your numbers: 5,4,3,2,1,0"

New to programming completely,on VB 10 Express. I am in the process of creating a keypad which I can punch in numbers 1- 9 to enter a password. I have 9 buttons for the numbers. I've got the keys to print the numbers into the textbox above but when I press a second key it replaces the first number in the text box.
My question is, how do I make the numbers go in sequence, so instead of
(Press 1) - 1 -
(Press 2) - 2 - (clears 1)
I want it to go like
(Press 1) - 1 -
(Press 2) - 12 -
and so on...

I am writing a matching program, and need 24 objects to randomly appear, each twice, across 48 spaces. I figured the best way for me to do this would be to assign the positions a number 1 through 48. but the problem is I can't find a way to generate a random number sequence in visual basic 9 .netI found many examples in visual basic .net but the conversion doesn't work. If not some code, many some example programs that either use a random number sequence or randomly sets the position of objects.

I have a timer that basically counts a number up in sequence in a label. On the On Text Change sub for the label I have functions run when the label is at a specific number. Everything works fine, the only problem I have is I have information pulled from an ODBC link to a pervasive database every second, which slows down the program. I have several flash components that run so slowly because of the data update. Now I have tried both using a dataset and coding the query but it is still ver slow and processor intensive, I think its because the Pervasive ODBC link is somewhat slow. Is there a way to have my data pull timer run in the background so that it doesnt effect the performance of the rest of the program?

I am using a mysql database and I am trying to get the number of results. I should only have 1 result because this is for a username/password login. I tried this
If loginReader.HasRows Then
'do whatever here
Else
'do something else here
End If
The loginReader gets the results and does the ExecuteReader. The problem with this is that if I use a good username and password it works but if I put in a bad username and password it doesnt do either one of them. Any ideas on how to just count the number of results?

I am currently building a search page, which includes a textbox and two drop-down lists, a search button, and a datagrid. If results are found and displayed, I would like a label to display:
(e.g.) "24 results found for 'blue sky clouds' "
...where the integer represents the results count, and the keywords and/or drop-down list selections are included in the string.If no results are found I would like the label to display:(e.g.) "No results were found that match your selection. Please try again"I would also like the label to be invisible until a search occurs.

I have code that's working beautifully on my development machine, but when deployed to the server is throwing null reference exception. So, I can't step through the code, but I've pinned down the culprit. But now I am puzzled.[code]In the code above persons is a dictionary of custom class, and certs is of IEnumerable type. Now here's the quandary.. The first line that sets the label returns False, so certs is not null. But the second line throws an null reference exception.

I'm trying to animate a game piece by using a picture box where the x,y location is changed as the image changes (cycles through a walk animation sequence). This all works fine, however it's too damn quick. I've tried slowing it down using a simple:
for z=1 to 1000000: next
While this works-ish there must be an easier way to slow down code....is there? On a related matter: Why does picturebox animation look so crap compared to combining images in the paint screen section? My picturebox seems to flicker every few frames.

I have this code to return a list of fund sources for our organization.
Dim FundSourceList As New List(Of FundSource)
Dim fs As New FundSource
If results.Count > 0 Then[code].....
The problem is that when I loop through the resulting FundSourceList all it shows is the last value. For example, if I have three fund sources (state, federal, athletic), then when I use this code to loop through all I get listed is athletic, athletic, athletic.
For Each FundSource In FundSources
Debug.Print(FundSource.FundDescription)
Next
So I change the code to this. I moved the creation of the fs variable inside the loop.
Dim results = From result In dsResult.Tables(0) Select result
Dim FundSourceList As New List(Of FundSource)
If results.Count > 0 Then[code]....
This works fine but now I'm creating a new class over and over again. It seems a little inefficient to me. Can I not create the class outside the loop and use it over and over again?
