Getting Number Of Rows In Table To Display In Database
Aug 23, 2009Any method that can effectively get the total number of rows that is StartRows to EndRows in a database table and then get the corresponding data from that row as currently I am having difficulty in retrieving out the correct row of data to the column that I am comparing. It will always get the first row of data regardless of which row I put in the handphone number which I'm comparing to. The codes below is the one which I am currently using now to detect the maxrows in the database and also to retrieve the corresponding information.
MaxRows = ds2.Tables("CustDetail").Rows.Count
MaxRows = MaxRows - 1
Dim numbers() As Integer
Dim EndAt As Integer
inc = 0
[Code] .....
I used a msgbox(n) to see the number of rows in the database but it displays only one where I have two rows in my database. The for loop is the one which will detect the number of maxrows and also retrieve out the corresponding details. But apparently this is not the appropriate way.

View 1 RepliesSelect And Display Matching Rows From A Table?
Apr 22, 2010For a project i am working on, i am taking bookings. These bookings are stored in a database alongside a users personal details. The personal details are assigned an ID according to the user who booked it. A user can book more than once with different personal details.
My problem is that i want a user to be able to edit a booking. I want a list of all the names that user booked to be listed in a combo box. This is the part i am having trouble with. i am using an access database and using sql statements to pull out the data. This is what i have tried so far:
SELECT [First Name]
FROM PersonalDetails
GROUP BY [First Name], UserID
HAVING (UserID = ?)
If i execute this query in the query editor, it works and shows the two records currently assigned the input id. However, if i try to output this to, for example, a text box, then it remains blank. I am assuming thisis because there is more than one output, but i'm not sure.

I have changed my application. Now it has two separate datagridviews each using the code above (seperate bindingSource and GridView). One each in it's own splitcontainerpanel one above the other.

View 11 RepliesDisplay The Rows Of A DataTable Derived From Other Other DataTables On Textbox (Typed DataSet)?
Mar 29, 2010I created a DataSet using the DataSources wizard. I can display the rows of each Datatable one at a time. But in this case, I needed to add a new DataTable (newDT) using the Add New Table Adapter control(?) on the toolbox. newTable is derived by JOINing three different existing tables (or, dataTable) in my DataSet designer. The query works fine and returns all the data as expected. Trouble, if I try to display the rows of the newDT on textboxes, I get a NULLREFERENCE Exception.

Game Programming :: Have An String Array Called ArrMap (0 To 19) That Holds The 20 Rows Of Each Map For Display?
Sep 30, 2009Im working on a roguelike console RPG. For those of you that dont know, just google search it.What I need help with is that I have an string array called ArrMap(0 to 19) that holds the 20 rows of each map for display. I also have an array of the same size called VisibleMap that needs to hold which portions of the map are visible and which arent so that when the player switches screens [IE goes from map, to inventory] they can go back to the map and it will look the same. I was thinking of using an array, but if you can think of another way to do it, that's fine.Here are the subs that deal with the map reading and display, so you know how I have things set up at the moment.
Code:
Public Sub ReadMap(ByVal location As String)
Dim ioFile As New StreamReader(location)
Dim ioLine As String
Dim intX As Integer

"No Room Is Available To Display Rows"
May 4, 2010"No room is available to display rows." (VB .Net)
I am getting above exception when trying to set the grid property "FirstDisplayedScrollingRowIndex".
Form1 and Form2 are MDIchild form. Form1 has a datagridview, and form2 has a command button. On click of the command button the grid gets populated and everytime I click, certain number of rows get added to the grid at the end. After populating the grid i am trying to set the scrollingindex to the first row of the last set of rows added.
When form1 is closed or open and i perform the click event, the index gets set properly without giving any exception. But when I minimize form1 and perform click event, i get exception "No room is available to display rows." is getting diaplyed.

Alternative To SQL CE?
Jul 15, 2010I've created an app (VB.NET) where each installation of the app works with a single local database on the PC. No multiuser and no ability for the user to change databases - the database is effectively part of the app, with a fixed scema, only the data will change.At the moment the database is SQL CE. It has about 30 tables with some simple relationships between the tables.
I'm wondering if there is an alternative to SQL CE that might be faster in this scenario. Although SQL CE is excellent and easy to use, I get the feeling there is perhaps an unecessary overhead when using it for something simple - and it does seem a little slow when my app is doing complex stuff that interacts a lot with the DB. In my prototype I actually loaded the 'database' tables from text files into Arrays and developed subs and functions to perform the database searches etc. It was blindingly fast but I realised it wasn't a scaleable solution because it was an 'in-memory' database. A compromise would be to 'page' data into array when needed, but it all gets horribly complex and that's probably why some very clver people have created SQL CE !
Add Rows Inbetween Rows In Gridview Based On Parent And Child Node
Jan 19, 2011I am working on Treeview control and Gridview Control VB.NET08. In the Treeview i have Parent and Child Nodes. Like: [Code] Comparing the Parent Node text and first two digits in the Column values. I want to add rows inbetween the gridview rows based on the parent and Child Nodes. If i expand the First Parent Node Called "31" then according to the Number of Child Nodes (for first parent node(31) there are 5 child nodes.) add rows in the gridview.
These New rows should be add under the 31-xxxx. If i expand the 32 Parent Node based on number of Child Nodes, add rows under the 32-xxxx. [Code] I am getting the rows in the end of the Gridrow not in the Specific row.
VS 2008 (DataGridView) :: Delete Successful Inserts Of Rows And Move Rows Up?
