Compare With Id And Retrieve The Name In A Table
May 31, 2012
I am doing a small program in vb2005 with access database. In that I have a small issue, my database has 3 tables tblbill having vendorid & truckid to compare, tblvendor has vendorid & vendorname, tbltruck has truckid & truckno in these 3 tables i want to retrieve and show the vendorname based on the truckid based search. I have written code for some level and it doesn't work for me.
This is my code
Dim cmd1 As OleDb.OleDbCommand
cmd1 = New OleDb.OleDbCommand("Select tblVendor.VendorName, tblTruck.TruckID, tblbill.vendorid, tblbill.truckid " & _
[CODE]...

I want to write a program using vb.net tht compares the name of a document on my desktop to the name of the document on the server. If they're the same then I'd like to retrieve it and have it replace the file I already have.How can i do this? Does this mean that i have to write a web application cuz i hope not. I dont no anything about those. I am using that server for storage purposes only so i assumed that i didnt need a database for the name of the document.

So, how can i do this? Is there an existing class/package in vb.net that does something like this?

I'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)

I need comparing value from the same table for my final project.
Example :
Table 1 :
SubjectCodeClasses
Sub Aclass 1
Sub Aclass 2
Sub Aclass 3
Sub Bclass 2
Sub Bclass 3
Sub Bclass 4
Sub Bclass 5
Sub Cclass 6
Sub Cclass 7
Sub Cclass 8
...
My task is, I need to compare the classes in the subject. Sub A with class 1, class 2, class 3 have to compare with Sub B and Sub C. if classes from Sub A exist in Sub B then the output is 0, if not the output is 1. then Sub A again will compare with Sub C and the rest. After Sub A compare its value with other subject. Sub B will start comparing with all the subject and so on.
Below is the concept.
Sub ASub BSub C
Sub A001
Sub B000
Sub C100
I really don't know to do the loop..

My application is in VS2008 coded in vb.net.I have a table with three columns FromDate,Todate and Schedule.FromDate and ToDate will have date values whereas Schedule will have a any of these values(weekly,Monthly,Yearly) In my Form i have given some provision to the user to check the records.
My requirement is The currentdate that is Today's date should be compared with the values of Fromdate and ToDate.First it should be check whether Schedule value is Weekly or Monthly or Yearly.If it is weekly than it should check the record in between fromDate to ToDate with a increment of one week.That means it should first check the first value of fromDate than add 7 days to the value and then again check from fromDate and this should continue till it reaches Todate.

I have to compare an item value in two tables. these two tables are on different database(same server).
I have succesfully generated sql query to return both table values.
the query runs in sql server without any problem and gives the results.
The same query i used in vb.net doesnt gives any result ...
It is resulting with no rows.
Does the connection to multiple databases wont work from vb.net.
The following classes are used to get the result ...
SqlConnection
SqlCommand
SqlDataAdapter
SqlDataAdapter is showing with no records returned. The same query returns the results in sql server query window...

My query is i want to save record from an excel sheet to my Database Table.
But i dont want to insert the Excel sheet as a whole rather i want to insert the record in my database table Row wise.Inserting the records is not the only thing but my major issue is i want to check and compare the Primary Key column of my Table with the Column in my Excel.
Suppose Table1 is my Sql Database Table,and RegistrationNo is the Primary Key Column.Similarly there is also a column of Registration Number in my Excel Sheet.
Now before inserting each record the RegistrationNo column should be compared.If the a registrationNo in the excel sheet say RegistrationNo 112 is already present in the table then it should not Insert the record and if its not present then it should insert.
Also the other issue is the number of columns in my Database table are more than the number of columns in my excel Sheet.So the columns that are not present in the excel sheet should be set to NULL while inserting the record in the Table.

I have been requested to implement a login form into a friend's Visual Basic .NET application. He specifically requested that I should do this using LINQ to compare the input to a table in an Access database. I don't really know why he imposed these restrictions, but who am I to judge? However, the problem is I am not overly familiar with VB .NET, or LINQ.

I would like to retrieve the datatype of a specific element from a SQL table. The situation is that I am importing data from a source that does not match column-to-column with my SQL table. The objective is to compare the datatype from my source file to what it MUST be when I write it to my SQL table, and throw an error on a mismatch. I would like to do this without creating a class that contains the layout of my target table if possible.

Here is my problem:I have 2 tables Accounts and Transaction Logs.in Accounts table, it has column "Amount" which is a base amount of an account.and in Trans Logs table, it also has column "Amount" which is additional (add or minus to the base amount) amount of the account.and I don't know how to retrieve that base amount to edit it, then save it back to the table.That means I need to get a value of the right column by using Acc_No to find. I'm using DataSet, by the way.i think it should go like this:
Dim Amount as Decimal
Amount = *the code to retrieve the base amount*
Amount = Amount + txtAmount.Text
*the code to save the new amount back to Accounts table*

Is it possible to have a quick and easy way of retrieving the last 10 records from a table?
Currently what I have been doing is retrieving all the records then one-by-one cylcing through each record until I have the last 10. To me this seems to have a lot of over-head reading each record. I just wondered if there was a quicker way of doing it.
