How To Detect Number Of Rows In SQL Database
Sep 12, 2009
I am currently having trouble detecting the number of rows in the table in sql database. I have one column as auto increment, and one column that will show the blkname. But everytime I delete off one row, the program cannot run saying that there is no row at position "up to the latest number". Then, when I try to insert back the row again, the program also gives me the same error. I think the program probably cannot detect the number of rows correctly as it cannot like detect if there is 5 rows in the database and if you delete one row, it will give me the error. The above method is the same if I used the auto increament column and without.
The code that I have wrote so far is :
'AUTOINCREMENT
Dim n As Integer
Dim inc As Integer
Dim numbers() As Integer
Dim StartFrom As Integer
Dim EndAt As Integer
Dim MaxRows As Integer
MaxRows = ds2.Tables("CustDetail").Rows.Count
[Code] .....

I am using a tableadapter to connect my project to an MS database. I need a a function which counts the number of rows in the table for something which I am doing. I have sucessfully used the count function to count the number of rows for my other tables, but when I tried to reuse it for another table, it wouldn't work. I get an error...
An unhandled exception of type 'System.ArgumentException' occurred in System.Data.dllAdditional information: Input string was not in a correct format.Couldn't store <AH25> in ProductCode Column. Expected type is Int32.
and this is the code which I used
Dim record As Integer = TAProduct.GetData.Rows
Do Until record = TAProduct.GetData().Count
' other codes
loop
It only seems to work if the first column is an integer datatype, which is the case for my other tables, but the table which I am currently dealing with using a string datatype. Is there another way to count the number of rows without using SQL statements or can I adapt my existing code in some way?

Any 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.

I am trying to program a noise reduction algorithm that works with a set of datapoints in a VB.NET DataTable after being helped with my other question. Basically, I want to take two integers, a coordinate value (yCoord for example) and a threshold smoothing value (NoiseThresh), and take the average of the values in the range of (yCoord - NoiseThresh, yCoord + NoiseThresh) and store that number into an array. I'd repeat that process for each column (in this example) and end up with a one-dimensional array of average values. My questions are:
1) Did anything I just say make any sense ;), and
2) Can anyone help me with the code? I've got very little experience working with databases.

I am trying to figure out a better way to basically predict a random pattern from a previous set of numbers. I figured the best way would be to use a for next loop and try different random seeds until a pattern matched, but it seems that it would take forever Lets say you had 3 random numbers: 2, 5, 12
Code:
Dim RandomGenerator as New Random()
Dim FirstNumber as Integer = 2
Dim SecondNumber as Integer = 5
Dim ThirdNumber as Integer = 12
[code]....
The above code does work to an extent, the problem is it takes so long to process. Is there any way to feed in the random numbers and have .net spit out a seed that matches them?

In VB.Net, is there a way of auto-detecting the culture of a string representation of a number? I'll explain the situation:Our asp.net web site receives xml data feeds for boat data. Most of the time, the number format for the prices use either a simple non-formatted integer e.g. "999000". That's easy for us to process.Occaisionally, there are commas for thousands separators and periods for the decimal point. Also, that's fine as our data import understands this. Example "999,000.00".We're starting to get some data from France where some of the prices have been entered with the periods and thousands separators the other way around as that's the way it's done in many European countries. E.g. "999.000,00". This is where our system would interpret that as nine hundred and ninety nine pounds instead of the nine hundred and ninety nine thousand pounds that was intended.

Simple question but it is killing.
How do I write an expression, that return the number of rows where a column is equal something.
I can get the total rows like this: =Count(Fields!Foo.Value) and RowNumber("Rapporter")
But I can't get the number of rows where Foo is equal to someString
Foo is a type string.

I am trying a small application here. It is a windows mobile application. I have to create a form with one drop down and a datagrid.Once a value is selected in the dropdown. The focus goes to the data grid.I know before hand that there is only one column. But I dont know how many rows the user will enter.When the foucs comes to datagrid then one row is created where the use will enter a number. When he hits tab or enter a new row is created and the cursor goes there and the user can enter second number. When he tabs or etnerts a new row is created. This should go on until he presses Save button when all these values will go in the database table.

I'm trying to run a simple select statement using an ADO recordset. But the resulting recordset returns 3 times the number of rows. For example the query should return 20 rows but is repeating 2 more times and returning 60 rows. When I run the query in Oracle it returns 20 rows.
