so here is my scenario. I have two input files... both are plain text files. File1 has customer name, customer address and invoice number. File2 has customer name, customer address, invoice number AND a keyline. File1 will only contain some of the records in File2, and it will change daily. I need to be able to compare File1 against File2 and output one file (preferably an Excel spreadsheet) with the info from File1 and the keyline from File2, that matches the duplicated info. I know the basics to get it to work, but I'm not sure what would be the easiest way of doing this... File2 can have up to 100,000 records per day. I'd only need to run it once a day though.

I want to filter my results with respect to date and time....I have date stored in a separate field which is of datetime data type...Another field stores Time value but as it is a datetime data type so it stores current system date along with the entered time. Now when I filter results using date then it runs well and shows the results between specific period like between dates from 12/10/2011 and 12/15/2011...But when I want to show results with respect to time it doesn't show any results...
I am using dataadapter and dataset for retrieving records from the sql server database... Please tell me the solution for comparing time value taken from the textbox with the datetime value stored in the database so that i get results between specific time like between 12:00 pm and 6:00 pm.
Actually I have datetime value stored in the database. What I am taking from the textbox is a time value. I want to extract those results from the database which are between the given time value....To be more concise, my application is a booking system for a sports club and provides an option to view alreaady made bookings.. Here i offer two options either to view all bookings for a specific game or to filter bookings. In filter bookings one option is to filter through date and time...Date option is running okay but problem lies in time part...I provide two times but unable to view bookings between them...
My code is:
Dim prmtimefrom As New SqlParameter("@booking_time", SqlDbType.DateTime)
prmtimefrom.Value = TextBox3.Text
Dim prmtimeto As New SqlParameter("@booking_tim", SqlDbType.DateTime)
prmtimeto.Value = TextBox4.Text
[code]....

I need to compare 2 files one on a PC in country X and 1 on a PC in Y.Country X and Y could be any country in the world.
When I compare the last modified dates of the files, it returns the local modified time, so they are always different.

I need to obtain time values from a SQL DB. However, I was able to set the datatype for the respective column in the SQL table only to "datetime" as there is no "time" option in the dropdown list in the Visual Web Developer. Namely, I want to bind a Listbox control only to the time data (i.e. not to "dd-mm-yyyy hh:mm:ss"). I tried to convert the datetime values to string and then extract the last 9 chars that refer to time.Unfortunately, my attempts to do that with SubString have failed:
weekDays.DataTextField=Convert.ToString("Start").SubString(length("Start")-10,9)
where:
weekDays - ListBox

Is there a way to compare two dates (which include time) ignoring the time? I have a 1/1/2009 8:00am and 1/1/2009 9:00am and I just want to know if it is the same day, without any care to what time it is. I know I can convert the date and compare the strings, but is there another way?

i want to create an system that can trigger alert which, the alert box will change to a red color depending on its value.
my problem is, the value that i used to compare is dynamic and based on what user key in in the paramater table while the data that will be display the alert is from the alert table.
lets say the value in the parameter table is been declare as Aand the value that display the alert is been declare as cellvalue.
this is the code that i have been tryingif cellvalue < A then' some code to change the box colorEnd if
but i kept failing. the system cannot read the A value.

I'm a little brain dead at the moment and was wondering if someone could help me out with some code.I am pretty new to using databases in vb and what I want to do is to match a variable with a value in a database field and when it finds it, it will store the row count into another variable. I know I have to use a counting loop, I'm not sure how to compare the variable to the value in the database.[code]

I have a connection string set up and a data reader.I have two textboxes on my form for users to type in. One textbox (txtLogin) is a user name and the other textbox is a password (txtPwd). I'm trying to compare what a user types into those two boxes to a table in a vfp database. The table I'm trying to compare to is open about 99% of the time so I need to be able to read from it in some type of "shared" mode.
My Select statement needs to be something similar to "select * from sites where clogin = txtLogin.text and cpassword = txtPwd.text"I just don't know how to get this to work properly.

i want to compare between the cell value with the value(parameter)in database.
as example, if my cellvalue value is 3 and my paramater(a) in my database is 5 it will be like this if cellvalue<a then (some code)end if
the problem is i don't know the exact data type. the reason i need to use data type is because my data is dynamic.
here is my code:
Code:
protected SubGridView1_RowDataBound(ByVal Sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
con = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;

I have a tblVersion that contains the versions of my application:
VersionID Version
VersionID is a bigint primary key, version is a ntext column that holds the current version... I want to be able to pick the row that has the highest version number, but version could be in this format:
MyApplication 1.0.1
If I try to convert that to a int32 it will throw an exception obviously. I would like to know if some of you have a idea how to solve this issue. I could of course make sure the column will only contain numeric values but this gives a little more flexibility.

how to create a comparison statement for a record that I have placed in a column of a SQL Database. In other words, I have a 2- forms, the first form is where the enduser places a few record requirements along with 4-digit number followed by the submission of a registration. After the registraions is submited, I have it coded to where the registration gets saved along with the 4-digit number into the database followed by a second form appearing. Ok, here comes the problem: When the user exits the applaication and then restarts the application again, the first form apears although it is not necessary since the enduser had already registered.
So, how do I or what kind of comparison statement can I create that will let visual basics or the first form know that the registration was completed and force the second form to appear instead or first?I would liked to makes some type of comparison with the 4-digit number thats in located in the SQL database.

I have a question about how to get a button to check for a textbox contents, and then compare that with data in my fairly simple database (It's meant as a login procedure).
Here's my database:
It has 2 values, 1 for the manager and 1 for the Admin
Here's my Login screen:
Now...
Everything works just fine, all the code is correct so all the buttons work. For the program i'm making, there's 3 types of users, 1 user who can only change how much money a customer owes the company, 1 user that can add new customers and other little things and one Admin who can change pin numbers and manage backups and stuff like that. For the last 2, i need pin-number/password protection obviously.
The user should enter the pin and then press ok, after which the ok button checks if the pin number the user entered, corresponds to either identifier 1 or 2 (5566 or 6655 for now) and if correct, show the user the next form.

I am trying to figure something out. I have an application in which I am adding the ability to consume a feed. I have no problem with the feed itself, but my problem is how can I mark certain items as 'read'? The only thing I can thing of is to read the feed into a database. In this database, I add a column for 'read' which I update when the user has read the article. Then each time I retrieve the feed, I compare the feed to the database and only load new items into the database.
