View 1 RepliesGetting 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.

Forms :: User To Be Able To Select Any Number Of Those Checkboxes/rows And Then Return A Value To The Table "stamping" That Users ID?
Jan 8, 2010I'm working on a project and my boss insists I use a DataGrid for this. The grid holds information for work orders, one of the cols has a check box in it. I need the user to be able to select any number of those checkboxes/rows and then return a value to the table "stamping" that users ID. This is what I have so far to get the grids populated... I'm using 2005 with a 2000 Access Database if that helps. Though this will be changed to SQL Server once we get it working (yay more work)...
[code]...
I removed the code from the second grid to make it easier to read, obviously once I can get one to work the second shouldn't be as much trouble.
This is the check box: dgvNewBiz.Columns(1).HeaderText = "Select"At this point if someone knows how to get it to recognize the click event of the check box and pass that row info to a variable that would be super as I'm sure I could probably figure it out from there.

Using ODBC Works Fine On 32-bit But Unable To Locate ODBC On 64-bit
Oct 24, 2011I have a small vb.net application that fires a crystal report through crystal viewer.
The report uses an ODBC connection provided by 32-bit software accounts package, which is installed in the ODBC 32-bit This all works fine on 32-bit XP and 32-bit Win7 with no problems, When run on a win7 64-bit machine the application launches ok, but when it comes to running the report, it prompts for a database logon box for the odbc connection.
When the report is run seperate on its own, on the exact same pc through crystal reports desginer it runs fine, Its almost like the application is not picking the 32-bit ODBC set up is it the case that the connection needs to be coded rather than using the report connection,

View 1 RepliesCompare All Rows In One Table Against Another Table?
Aug 12, 2009I've got a table in an SQL server that often has large amounts of data imported into it via an automated process - the problem is that a lot of the data that gets imported is a duplicate of data that is already in there (for example if we have a customer in there called Mr Customer Ltd, a duplicate with a slightly different name could get imported, like Mr.Customer Ltd).
So I am using the Fuzzy Logic class that Wild Bill put in the CodeBank to find names that are similar and then highlight these items. The thing is that the target table that the imported data ends up in has several thousand rows and the table that contains the data to be imported often contains several thousand rows as well, so I'm trying to decide how to do this. Obviously reading both tables into memory is not an option as it will consume too much memory on the client PC that is running this app. So this is what I am doing at the moment:
1. Read the table that contains data to be imported into a DataTable in memory
2. Open a connection to the target table and use the SQLDataReader to start to loop through it
3. In this loop, for each row that the data reader reads I then loop through the entire set of rows in the DataTable and run this fuzzy logic method that compares the account name from the current row in the datatable loop to the account name in the row that the datareader is currently on.(there is also a Thread.Sleep(1) after each row is processed to prevent the process from eating up 100% of the CPU while it runs)

Counting The Number Of Rows In A Database?
Apr 30, 2009I 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?

View 2 RepliesHow To Detect Number Of Rows In SQL Database
Sep 12, 2009I 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
