I have been trying to get the Alert Code from my printer at work to see what exactly is happening however each time I send an SNMP query it doesn't return any results. I am using SimpleSNMP references. The printer is a Canon iR-ADV C5045.
This is how I call the function:
Dim strAlertCode As String = SNMPQueryGet("1.3.6.1.2.1.43.18.1.1.7")
This is the function:
Private Function SNMPQueryGet(ByVal OID As String)
Dim strResult As String = "True"
Dim host As String = "192.168.1.202"
[Code] .....
I would like to create a vb form with a combo box (with song title), a text box (for song lyrics), and a button (to submit or refresh). It is linked with an access database. The combo box is populated with the songTitle field in the db (this part works fine). The text box is populated with the lyrics that go to that song The first updates fine but I can not figure out how to run a query to pass to the text box's text property. I want the user to be able to select a song from the combo box, click the button, and have the text box populated with the new song's lyrics.
Any suggestions on how to accomplish this, or a good place for a tutorial that explains the necessary elements for having vb query a database and return the results?
I'm using Visual Studio 2005, and I have a datagrid connected to a table from an Access database.
I added 4 textboxes so the user can type search filters to search within the table and a "search" button.
Then, I created a query using the "add query" tool on the datagrid. I wrote it like: select field1, field2, field3, field4, field5, field6 from table where field1=? and field2 like "%"+?+"%" and field3 like "%"+?+"%" and field4 like "%"+?+"%"
Both field5 and field6 aren't search criterias, so I didn't add them to the query. Once the query was created, I replaced the parameters inside the procedure with my textbox1.text, textbox2.text, textbox3.text, textbox4.text and then cut and pasted the whole thing inside my SEARCH button click event, so the query is executed when the user clicks on the button.
Now the problem is: when I search using the first field it goes ok, but when I try to search by any of the other fields it returns zero results, even though I double-checked I had written the words correctly. I don't know why it does this. I already tried deleting the datagrid and creating it again.[code]...
how to take a query that returns a single row of data and load that data into textbox controls.I know about ExecuteScalar but it is only good for a single column of data from the query.
I am connecting to an Access database and using a parameter query with the LIKE operator to return all rows that match query. The string to search for is taken from a Textbox
sql =
"Select * FROM Allview WHERE Info Like" & "*" & CStr(TextBox1.Text) & "*" The query does not return any data in vb, but when run from access with same string, there is data returned.The connection to the database is done correctly, as I am able to return data with various other queries.

I am trying to get the html response of a Kayak.com query using a WebRequest object, however more often that not the site returns no results, i just get an empty Kayak page, i have to try the request around 5 times before i get a result back. What can be the cause of this? [Code]
So basically, I am running through my selected path recursively and returning the results to an array.. I think. vb.net Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim path As New FolderBrowserDialog If path.ShowDialog = Windows.Forms.DialogResult.OK Then Me.TextBox1.Text = path.SelectedPath [Code] .....
I was told that to return the search to an array, I add the return toarray() at the end. Now obviously Im not getting errors, but I am also not polling the results that are in fileslist.toarray(). I've looked at arrays quite a bit, I see their functionality if they are defined like myarray(4) with 5 declared array values... its an array with 5 value places. And to read from any one of the 5, you'd say something like msgbox(myarray(3)) to call the 3rd place in the array.
Well, as you can tell from the code, I am putting a variable amount of information into the array, How can I call that information? If I scanned a folder with 300 files, how can I call the results of that array and put them in a text file, or console, or messagebox through them? And assume I am doing it through a button click event. So, button click to read all input in the array to console or something like that.
Currently I have a gridview bound to a datatable which is populated with groups from the AD. I need to be able to add search functionality so users can type in part of a group name and have the results display only groups that fit their search criteria.
I am running a query in a thread but I can't figure out how to get the result back to the calling function. I am doing something like this:
Threading.ThreadPool.QueueUserWorkItem(AddressOf RunThread, "some query string") Private Function RunThread(ByVal stateInfo As Object) As String Dim myQuery As String = stateInfo.ToString
I am developing an ASPX web page to return results from two SQL stored procs via VB. When I execute these two stored procs, they both return valid data. But for some reason, when I run this report it doesn't return any errors, however, it doesn't return any records/data either!
Also, I can't debug it for some reason, although I can set breakpoints! This is using VS 2008, but I think reason I can't debug is I believe this is a limited version that just works for SSRS and SSIS.
[Code]...
Could the problem be due to the fact that this web page uses the same SQL connection for both stored procs? The first proc should be returned initially, and the second proc after this screen. So I don't need both stored procs information simultaneously, so I would think I could reuse the same SQL connection.
OK, I found where the problem is located. If I just comment out the Level statement in the Where clause, it does return data. So only thing I changed was that one line in my SQL code and it works. This means missing data must be due to datatype incompatibility, no? What is the problem?
[code] BUT, in code, watching the locals window for rec.EOF and rec.BOF both return true and therefore no results.Why does this work in VB Query Designer but not in code? If I remove the WHERE statement than the results return fine as expected.But its returning ALL of the results which is no good.
The following code works just fine: Dim wksSheetNames(0 To xlsWB.Worksheets.Count - 1, 0 To 1) As String Dim i As Integer = 0 For Each Wks In xlsWB.Worksheets Wks.Activate() wksSheetNames(i, 0) = xlsApp.ActiveSheet.codename [Code] .....
What is the best vb.net based search method that would permit me to search for i.e. "Sheet2" and be able to obtain "Cats"? I attempted to ascertain the index number of "Sheet1" with: Dim SheetArrIndex As Integer = Array.IndexOf(wksSheetNames, "Sheet1")
Then obtain the value "Cats" wksSheetNames(SheetArrIndex, 1)
But I received an error message: Code Line ->>>> "Dim SheetArrIndex As Integer = Array.IndexOf(wksSheetNames, "Sheet1")" Error msg ->>>> "Only single dimension arrays are supported here.: Obviously I do not know how to Search and Return the results of a 2D array.
Trying to find some code to assist with accessing a web service. I am a newbie when it comes to web services and don't quite get the whole how to submit the request and then read the results. I know from searches that people request a copy of the WSDL file so I have attached (SystemManagementService.wsdl)
I have setup an OleDbConnection and my query works just fine but the problem I am facing is that I want the entire query not just a certain row or column. I also would like to place this entire query into a blank excel spread sheet.[code]
If this is in the wrong section, I have a program that queries a database and puts the info in a specific format in a txt file. Now my problem comes w/ how to format the date.
Should I format the date in the SQL query OR is there a way to take the result from the query and format sometime before it is writen to the txt file? I'm not exactly sure how to do either. Would I need a subquery to get the desired date format?
I am using an access DB and wanted to create a query that returns user's in the db. First I need to check the db to see if it is empty. Then I need to check to see it my query returned any values. How do I go about doing this?
I'm a bit confused on how to grab query results. With VBA i would open a record set and have the results of the query written to that recordset. IN VB.net how can I grab the query result and throw each column into specfic arrays?[code]Now how would I force it to query my DB? I have a connection established already.After the query how can i play with the columnes and place them into arrays?
I had this query sp_msforeachdb 'select "?" AS db, * from [?].sys.tables' when I execute it in sql server, it return multiple results. How I can read all the results in my vb?
I am familiar with the VB6 ADO way of dealing with SQL queries and looping through the record set results.
However, what is the correct way to query a server, cycle through the results, and dispose of my query in VB.Net? All the ways I have been using seem to be unstable and crash randomly.
I have been using the following code:
Public Function GetSQLTable(ByVal strSQL As String) As DataTable Dim table As New DataTable Dim adapt As SqlDataAdapter
I am learning VB.NET and wanted to try and connect to a Oracle.DataAccess with this simple SQL Query but am stuck how to get my results.
Imports Oracle.DataAccess.Client Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click[code].....
I'm trying to execute a SQL query and pull the results into a text file. However, I'm getting an error in the bolded part. I think probably the biggest help would be an explaination of what the code in bold is actually doing. I pulled this from a book but don't think I completely understand. To me it seems like its saying that for each row in table 'extract'. Extract it, and write it?? But it doesn't seem to work that way. When it gets to that part, the error I get says that the row doesn't exist in the table
Private Sub btnExecute_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExecute.Click Cursor.Current = Cursors.WaitCursor 'hourglass cursor Dim connection As New SqlConnection
