I am trying to get a query to work with Visual Basic 2010 Express addition I have pasted the code below but it just errors out with to many arguments I have taken this sample from a reference book but cannot get the darn thing to work. I have looked all over the net and Microsoft for a solution but still no go if any one can help it would really be great. BEP
Private Sub FillBypeeps1ToolStripButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FillBypeeps1ToolStripButton.Click
I am making a calculator Program to start off on visual basic. I got it to work with MsgBox, but now I'm trying to get it to work with the Print.
MsgBox Example Public Class Form1 Private Sub Button1_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Button1.MouseClick Dim Pizza As Integer [Code] .....
Say I type in 6 and 6 I'm getting errors saying Example: Conversion from string "youranswer is 12" to type 'Integer' is not valid. I've tried many things, but it's not working. I want to know what I need to do to get it to print out how I want it. Do I need to do some conversions properly somehow?
Can anyone tell me what is wrong with this code? It looks OK to me but the GetImage function returns the same image irrespective of the filename passed to it (the one corresponding with Id=2 which is the second one found) [code]
My Com1.text has nothing in it but yet the button1 is still visible when it should be false and not showing. This worked fine in vb6 using command.caption.[code]
I have loaded my database with one table under "Data Connections" in the "Server Explorer" pane.What is the standard / best-practices way to handle a simple query in a VB ASPX page?
My left <div> would be a set of form elements to filter rows, and when the button is clicked, the main <div> would show the columns I want for the rows returned.
Note: Answers in C# are okay too, I'll just translate.
I am just starting to dive into the ADO.Net routines in VB.Net, have used ADO in VB6 forever just would like to make sure I am getting started on the right foot here.
'As I test I had hard coded the connection string here which I have removed from the post, I will switch it to a var that is read from a config file later.
CN.Open() Dim Cmd As SqlCommand = CN.CreateCommand Cmd.CommandText = "Select * from tblusers where userid=@UserID"
[code]....
btw I realize that I have not yet added a message for when the Userid is not found. I am more concerned with the method I am using to query the db and read the results as well as closing the objects afterwards.
So i know this is more Math related but it would make life so much easier. What i want to do is enter 2 times into 2 text boxes and then subtract them from eachother to find out the hours inbetween as a decimal.
I'm using vb.net express with access 2010.Everything is working fine except for a simple query:SQL: SELECT * FROM Customers WHERE Name Like 'Ale*'Which returns all the names starting with Ale. Now in my .NET code I wrote this:cmd = New OleDbCommand("SELECT * FROM Customers WHERE Name Like " & Chr(39) & Name.Text & Chr(39), connection)Now when I start the app and in my textbox "name" I write Ale* I have the following expression:SQL: SELECT * FROM Customers WHERE Name Like 'Ale*'But when it executes from .NET (dr = cmd.ExecuteReader) it doesn't find ANYTHING.
I am trying to query a SQL db and send the results to a notepad or wordpad doc. I have the VB code wrapping the statement and it works fine but I have to put the results to a doc so the user can preview and/or print.
I've tried different approaches to query a simple xml and compare one of it's values but none of them worked well.
Consider the following XML structure: <?xml version="1.0" encoding="iso-8859-1" ?> - <Shops> - <Shop> <text>Northampton</text> <value>NN</value> <currentdate>050809</currentdate> <labelcounter>1</labelcounter> [Code] .....
I have the shop name in a drop down list which is ShopsDDL and it's set to autopostback. What I want to achieve is: On postback, check for a xml node where node's text = shopDDL shopname And retrieve also this node's currentdate and label counter. Rhen, if the node currentday = today then increment labelcounter by 1 Else set labelcounter = 1 and currentday= today My problem is the XML query, I can do all the logic as soon as I manage to retrieve data from the XML.
I'm retrieving data from an Excel sheet, using a simple SQL query using a textbox as input to my variable. It works great when I enter an integer to search for (such as 213 for example) but when I put in a mixture of numbers and letters (48A for example) I get the following error: Syntax error (missing operator) in query expression '[P&L]=48A'.
Private Sub MPLS3() Dim BrNr As String BrNr = TextBox1.Text Dim stSQL As String = "SELECT [MPLS Date] FROM [Master Data$] WHERE [P&L]=" & BrNr & ";"
The code below works fine on my development PC, but when I deployed the app, it crashes.
Here is the lines of code that are relvant
Private TdsTypesList As List(Of TDS_Type) ... TdsTypesList = (From tt In db.TDS_Types Select tt).ToList

I have many queries that are using linq, and none of them throw any errors. The set of data is not very large either, less that 100 rows. I dont know if I have any other queries that do not have where statements in them that work.
Running .net 3.5 without sp1 on the client machine, although I am running sp1 on my development PC. looking for a solution that doesn't require sp1 to be installed.
Edit Code breaks on the second line when remote debugging.
I looked over [URL] and tried the following, with the same error.
TdsTypesList = tl.OfType(Of TDS_Type)().ToList
I finally found a dirty workaround. Instead of pulling all of columns from that table, I was able to re-write the query to omit 1 column. This returns an object of anonymous type, and I can use that object. I still would like to know what causes this though.
I have a project in Visual Studio 2008 and there is a working data connection to a MySQL database. In other words, I can query the db directly from Visual Studio and it will display the results.
I've tried a couple of approaches that I found online for writing a connection string and accessing the db, but no luck yet.
All I'm trying to do is code a button to query the db and then reset the text property of a label/textbox to display the results based upon another label/textbox value.
The pseudo-code I am imagining is something like this:
Private Sub query_submit_button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles query_submit_button.Click result_textbox.Text = SELECT field FROM table WHERE otherfield = key_textbox.Text End Sub
I didn't see any related questions posted on SO - forgive me if I missed one that already exists and this is a dupe.
I have read through soem other threads on this site and it has gotten me this far, but I can't seem to get over the hump.I am trying to create a table to reports back the proper data from a sql database based on what a user types in a textbox. I have pulled a dataset that i have already setup onto the tabl.
Public Class robsearch Dim sstring As String = "1234" Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
I am trying to read data from remote SQL base. I have written the function that works great if you need to get 1 Value , but when I want to read 2 or more value at from one query it doesn't work [Code]
When I'm trying to run this program Sql QUERY doesn't work properly , but the month and day are okay but it comes to year it doesn't work...

I'm new here, I have a problem with my query in my POS program.For a product I need to read the price of it, I made a connection with my database, it's succesful I've already tested it. When I click to a button then will a msgbox appear with the price of that product.

Basically i have a query string that when i hardcode in the catalogue value its fine. when I try adding it via a variable it just doesn't pick it up.This works:
Dim WaspConnection As New SqlConnection("Data Source=JURA;Initial Catalog=WaspTrackAsset_NROI;User id=" & ConfigurationManager.AppSettings("WASPDBUserName") & ";Password='" & ConfigurationManager.AppSettings("WASPDBPassword").ToString & "';")
This doesn't:
Public Sub GetWASPAcr() connection.Open() Dim dt As New DataTable() Dim username As String = HttpContext.Current.User.Identity.Name
[code]....
When I debug the catalog is empty in the query string but the WASP variable holds the value "WaspTrackAsset_NROI"
I'm checking if the application needs to update before the user starts the software. But, they have to enter a few items of data and then press enter. When they do, if an update is available, the application closes, my update app runs and then the new version is opened. I want to just update when the application is loading, so they don't have to waste time entering data if the application is just going to close anyway. But when I run the block of code to check for updates, I get an SqlException.
[code]Myself and a coworker have stared at this quite a lot and we can't figure out why it's not working. The problem is in the value for @ID (since it still works when I leave the other one parameterized). The funny thing is, Just a few lines of code above it I have a different query that sets a parameterized value for the same ID, using the the same choices list that the For Each loop is getting the match variable from.Choices is a list of longs, and when I use choices(0) to parameterize ID in a query, it works. But now down here in this loop I have the new match long, and it doesn't want to make it work for me.
I have two tables say "Table1" and "Table2". I made a UNION query and saved it as "AllTimesFailure". It is worth mentioning, I am using Access DB. When I am trying to fetch the records from AllTimesFailure through oledbDataReader, it says "The Microsoft Jet database engine cannot find the input table or query 'AllTimesFailure'. Make sure it exists and that its name is spelled correctly.". I double checked query name and found correct but the problem still exists. when I run the same query as I pass through my command object, it works fine in Access query analyzer and fetches records normally.
I'm trying to write a Vistual Studio 2008 macro to run a stored TFS query and display the results.Previously I've created a query and named it 'Assigned to Me' to display all the work items currently assigned to me.Instead of View->Team Explorer, click, click down the tree to My Queries then double click 'Assigned to me' I want to write a macro to automate these steps.
Sub TemporaryMacro() DTE.Windows.Item("{131369F2-062D-44A2-8671-91FF31EFB4F4}").Activate() 'Team Explorer DTE.ActiveWindow.Object.GetItem("tfsserverMyProjectWork ItemsMy QueriesAssigned to Me").Select(vsUISelectionType.vsUISelectionTypeSelect)
have a query in SQL, returns the results I expect, however when I copied this query to a bindingsource.filter call,I get "Missing Operand" errors
Me.ItemsBindingSource.Filter = String.Format("SELECT * FROM items WHERE (GETDATE()) BETWEEN (items.ItemStartDate) AND DATEADD([month], items.ItemOccurances, items.ItemStartDate)")
I've spent a whole day on this already without figuring it out. I'm hoping somebody can help me translate the following MySQL query to work for SQL Server 2005:
SELECT MAX ( messages.date ) AS maxdate, topics.id AS topicid, topics.*, users.* FROM messages, topics, users WHERE messages.topic_id = topics.id AND topics.user_id = users.id AND topics.forum_id = " . $forumid . " GROUP BY messages.topic_id ORDER BY maxdate DESC
$forumid is a QueryString value defined in the following VB.NET code-behind code:
