Filter Table And Show 100 Most Played Songs?
Jun 13, 2012
I have mp3 database (access). I want to filter table and show 100 most played songs. There is a field "PlayCount" which is increased every time the song is played. I know how to use TOP clause, but there is a problem when I want to sort results in descending order by "PlayCount" .here is the sql query:
SELECT TOP 100 * FROM Database ORDER BY PlayCount DESC this query returns 120 results. If I use "TOP 200" it will return 278 results. But everything works fine if I use ORDER BY Filename.

SQL statements:
SQL = "SHOW TABLES;"
Try
conn.Open()
The remarked area works fine when I'm accessing a specific table. I've successfully inserted the products_model field into the combobox too. The datagridview does show the table names in the db using the SHOW TABLES sql statment, but I'm not understanding how to get this info into the combobox instead.

I have a table (Projects) which is linked to projectVersions on projectID..projectVersions contains several columns on which I'd like to filter a returned project (and associated projectVersions) list. For example there is a "capacity" column and a "country" column. I am doing a filtered list of projects on one page and I'd like to include all projects where any one of the associated projectVersions has a capacity of 750ml and a country of "France" for example.It may be that a particular parameter is not set and so I pass a zero to indicate not to filter on that.I guess this needs some kind of subquery as when I try and do something like this: [code] it doesn't work as the "xxx" bit, being one-to-many, expects me to specify an item to get at the entities within and yet I want to query where ANY of the associated versions match one of the criteria.

I have a dataset filled with content from a XML file:[code]Now I want to have the most recent date of each asset written to a SQL database. At this moment i write al the records in the database, where I sort the dataset on Date, so the asset with the most current date is writeen to the database. Is it possible to do a 'filter' of the data first before writing to the database?I can use Max(date) is SQL to filter the correct records, but I want to do it right from the start.

I guess I just cant seem understand this correctly
Dim StatusClosed As String = Form11.Closed_Code.Text ' usually = S or ClosedSale or Closed Sale
Dim SubjId As String = Form10.add_Num_txt.Text ' usually = StreetName or Street Name or SN[code]....
If SubjId is StreetNumber or SN its ok , if its Street Number with the space I get error
If I place a ' around {3} in my afilter line then it works if the SubjId is Street Number but not StreetNumber or SN

When I use a command such as:
Me
.TableAdapter.Fill(Me.SomeDataSet.Table)
I am going out to the database, gathering the requested information and filling the dataset. Therefore, everytime I add a query to a table adapter, it is also going to the database to get the information. So, my question is, how do I fill a table in a data set with all the records in the database table and then, filter the information I've already collected in the dataset without going back out to the database again?

How can I get the album art of a song file in visual basic.net?I use the Windows Media Player control if that helps anything.You can get album art with the SDK for creating skins, so it might be a similar way here.

I have a database with a table that is a child to many other tables. I am using this child table as a datasource for a datagridview. I am using comboboxes to display specific fields in any parent tables, instead of the user seeing the foreign key. Everything is fine. However, I would like to filter the BindingSource based on text matches between any of the fields in the child table and the corresponding fields of the parent tables.

I can find out myself how to add a button to the Explorer context menu, but my main question is: How do programs receive commands at runtime? And can you do it in VB. NET? Oh, and no, I don't have any code because I have no idea where to start. So, I guess first I need to make my program a single-instance-application?

I am somewhat new to VB and I am currently working on a media player program. I used WMP to make a playlist with the names of all the songs in my library. Then I have my VB program open the library playlist and read all the music names into an array. This works perfectly until i get to a song title with a
(which is not the same as the ' on the keyboard) but readline reads them in as a black diamond with a ? in it. Is this an ASCII/ UNICODE problem, or something like that? How do I fix this? I checked the text file and it is correct.
