Access Database And Using A Parameter Query With The LIKE Operator To Return All Rows That Match Query?
Apr 28, 2010I 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 :

Query A Database And Return The Results?
Jul 22, 2011I 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?

May 10, 2011I've created a log in system using a database and query builder to return the correct values, however, once the users signed in I need to bring up the rest of their data from the same table in the database. How'd be the best way of going about this? I'm not sure whether the log in should be changed to use the primary key as well.

Read Text File With Tab And Carriage Return Format To Store Them In Array
Jul 1, 2009I have to text file in the following format :
Word[tab][tab]Word[Carriage Return]
Word[tab][tab]Word[Carriage Return]
Word[tab][tab]Word[Carriage Return]
I want to get all the words before the tab into one array or to create a new text file and the all the words after the tab into another array or create a new text file too.
Here my function to get the words before tab into an array :
Protected Sub MakeWordListBeforeTab()
Dim filename As String = "D:lao�0001.txt"
'read from file'
[Code].....
I wrote the above function to get all words before tab but I got all the words into array. I've been trying to use the Split method above. What is another method to split those words ?
I know this can be done with regular expression but I don't know regex yet. If you can show me how to get this done with regex it'll be awesome.

Sql Server - Store / Query Data In .NET?
Nov 23, 2011At the moment I am using Access & an OleDb connection to store data. I went down this route originally because I though that this was the best way for applications that I am distributing to my clients.
I would prefer to use something like SQL Server but is this a good idea for software I am distributing? Does the average Joe's PC have SQL Server pre-installed? If not, I suppose I can provide them with a link to download it for free?
Is there any better alternatives to Access / SQL Server?

Determine The Type Of Object To Use To Store A Linq Query?
Jul 3, 2010I am using VB .Net for this, so I don't have access to var or this would be a simple matter.Right now my query is as follows
[code]...
So I used this query in LinqPad to help me determine what the object would look like. I got back a IOrderQueryable(Of RSError) which then contained a IGrouping(Of String, RSError) for each grouped collection of objects returned by the query.However I ended up with the current object type of errors as IOrderedQueryable(Of IGrouping(Of String, RSError)) because of the cast error I am getting in VS.
[code]...
I'm not sure how to get rid of the VB$AnonymousType_1 Part of the returned object.Am I even on the right track here or am I missing something completely?
Search From 2tables Store Query Result In Datagridview?
Nov 24, 2009I want to make a search form the user completes the 3 textboxes and 2 datetimepickers. (so five components).
Also I have a button called search and a datagridview.
When the user presses the search button it searches into those 2 tables (depending on what user typed in the 3 textboxes and selected on 2 datetimepickers).
Example of search:
The user searches like this:
When it presses the search button the results will be stored in datagridview(first textbox is the field DB-20-RTS from table PatrimoniuMasini and the rest are fields from the specified columns (name of labels) from the second table FoaieParcursMasina -is the second row from this second table).
Here's the code in my search button (don't know how I can store the 5 things(2 datetimepickers and 3 textboxes in the DataGridView) . My problem is in understanding the property item of DataGridView(DataGridView1):
DataGridView1.Item(row_index,column_index) -general syntax
Here's the full code of button search:

Dim comandasql As SqlCommand 'cerere -interogare sql

Xml - Can't Get XPath Query To Return The Right Nodeset?
Jun 2, 2011I've got an xml file that looks like this:
<Records>
<Record>
<table>[code].....
What I need is to select all the ROW nodes, across all records, so I'm using something like this:
rowiterator = Me.XMLDocument.CreateNavigator.Evaluate("//table/Row")
which is working, but it returns a NodeIterator that only contains the first Row node in the first record!? As far as I can tell, that's the proper syntax for an xpath expression of "return all Row nodes with a parent table name anywhere in the document".
Query In An Application Is Return Date Of 1/1/0001?
Oct 27, 2010I am building an application where a button click runs a sql query and shows a user the next available date that they can process from. The problem was that it needed to be the following Sunday and not the following day.That code looked like this:
Public Class Form1
Dim ReturnValue As Object = Nothing
Private Sub Button1_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim connectionString As String
[code]....
"select payrolldate from payroll where(payrolldate <= getdate())and payrollran <> 'yes'")but when I add that query it just returns a value of 1/1/0001 as the date.
Return Result Of A TSQL Query In Program?
May 14, 2011I have a VB.Net program that will basically make a query to a remote MS-SQL DB using TSQL, return two columns (normally 4 rows/records), 1 is a datetime and 1 is a double. I will then need to return the average of the doubles (which is easy in VB.NET).
As I will need to run this query perhaps 1000 times an hour (programmatically with different input parameters for the query), I am looking for the most efficient way to code this up so that it will take the shortest time to run. I tried SQLDataAdapter and then using dataAdapter.Fill and sometimes it returns an empty set although the raw select query has values returned.
Return Type For Collection From LINQ Query?

[Code].....
I would then like to pass this to another function to calculate the totals for all the accounts in the collection. Is it best practice to return an Ienumerable, a generic list, I'm just not sure what works best with LINQ and the entity framework.
Sql Query Doesn't Return Any Results On Datagrid
Jul 7, 2010I'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]...
