Query A Database And Return The Results?

Jul 22, 2011

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?

SNMP Query Does Not Return Any Results

Jun 24, 2012

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"

Sql Query Doesn't Return Any Results On Datagrid

Jul 7, 2010

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]...

Access Database And Using A Parameter Query With The LIKE Operator To Return All Rows That Match Query?

Apr 28, 2010

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.

Partial code :

Run .sql Query Against Database And Output Results To File?

Mar 8, 2011

I am currently attempting to write a program that will take a SQL query saved as a .sql or .txt and execute it against a specified database, and output the results to file. I have seen some sample code of executing a SQL query line by line,
and writing individual results to file.

The query that needs to be run is only reading information from multiple tables, but is pretty lengthy to do line by line. Is it possible to execute or read the whole query from the .sql file, or a text file, and run it against a specified database, and
have the results of the query output to file in vb.net?

Query/search Database Showing Results In Datagridview?

Mar 13, 2009

I am making a project in VB 2008 that has a Form (form1) that allows me to add new records to a database, and another Form (form2) that allows me to search for records in a database. I have done Form1 already, but my problem arrives in Form2 where I have to query the database. This form consists of 1 textbox (txt_search.text), 1 button (btn_search) and 1 datagridview (datagridview1). The name of my database is db_extras_test2003.mdb and the table I want to search records from is tbl_contacts.

I know +/- the SQL sintax to query the database (SELECT * FROM tablename WHERE columnname = (here i dont know if i put the variable name i have set for the txtbox, or the textbox itself)).I want this in a way that I (or other users) type in the textbox, hit the Search button and the results are shown in the datagridview (i can show the results in another way if it is better to do so).I have done the connection to the database already. The code I have so far is the following, but it doesnt work

[2008] Query Database Using SQL And Displaying Results In Datagridview?

Sep 25, 2009

I had done this by using the query builder (in VS Studio) but soon found out thay I gain no points by doing it this way as I am not using any code. I have tried to adapt the code I had to insert data into my database, just changing the SQL sintaxa and some other bits, but it is not working yet. Well, it gives results, but I think it is still geting the results from the query I had built using the query builder. Here is the code I've got so far:

Public Class Form2
Private Sub btn_search_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_search.Click
Dim str_search As String = txt_search.Text
Dim str_dob As String = txt_dob.Text

SQL Select From A Table In An Oracle Database, And Show Results Of Query In VB Application

May 14, 2009

I want to (SQL) select from a table in an Oracle database, and show the results of the query in the VB application, in a Excel like manner (rows, columns, selectable, etc.). Or in a SQL developer manner. How can I do that? Browsed through a lot of tutorials and howtos on the internet, did not get anywhere. I think (and correct me if I am wrong) that it's gotta be something with DataGridView. But I don't know how to create and populate a datatable with the result of as Select statement, how to create a dataset.

Run Through Selected Path And Return Results To Array

Nov 20, 2009

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.

Web Page To Return Results From Two SQL Stored Procs Via VB?

Apr 17, 2011

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?

Syntax To Search (and Return Results) In Two Dimensional Array

Jan 11, 2012

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.
