Compare With Data In Database?
Sep 27, 2010
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 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.

I'm trying to figure out the best way to determine if there has been any data change to the actual database since my last data retrieval.I'm using a DataGridView to display the cache data to the end-user, but before they make permanent changes to the database, I would like to query the actual database to make sure that no updates have been made to the data source. I'm querying an AS400 system, so I have to use the OleDbDataReader object to retrieve data from the system. What is the best approach for this scenario?

I'm working on a project that will compare two textboxes and output the difference in a third textbox. To provide some background what I'm trying to do is compare a users active directory groups to another users groups. What I want this program to output is the groups the user already has, groups that need to be added, groups that need to be removed(basically unique values).comparing text will output an integer, or boolean. I need the actual difference outputted in text to have a working document of changes to groups.
Here is an example of what I want it do, but i'm only able to get it working using an excel macro.
Sub UniqueValues()
Application.ScreenUpdating = False
Dim i As Long

I am reading data from a provider and they have a column where ONLY the time is provided. The thrid party provider cannot change the format and that is what i have to work with. An example
[11:56PM][516]
[11:57PM][510]
[11:58PM] [510]
[code]....
I can read the data no problem. The problem that i do have is to calculate the time elapsed between records. Here I can safely assume that at most the time will cross over into the next day. I don't particularly care what date I assign to my DateTime variable so i just pick DateTime.Now and then I go through and use the TimeSpan object to calculate time elapsed. Works great except when the records cross midnight.way to do just a pure time comparison? otherwise i am left currently with converting the time into a military time and then using a simple integer comparison to determine of the date has crossed over into the next day. i then use DateTime.Now.AddDays(1) to assign the full date.

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...

I've been tasked with writing an app that reads in various text files(.csv, .txt) in different formats with different delimiters.I then need to compare certain data in these files and report the differences.There are a couple of columns that are common between the files, but they aren't in the same place, and there is inconsistent and unnecessary header info.There is extra data(columns) in these files that I don't need.Should I parse these files into a datatable? Should I create an object for each file type to format the data and get rid of the unnecessary info?I'm not sure about the best way to tackle this problem.

I have been tasked with creating an app that will read in various text files(.csv, .txt) and compare some of the data contained within.
I thought I would read in the files and convert them to datatables. Once I had them in a datatable I figured I could remove the unnecessary rows/columns and then sort and compare the pertinent info for differences. The difficulty is that the various files are formatted differently so I will need to get each type formatted correctly. Is this the best approach?
I have read in a .csv, parsed it into a datatable, but I'm having trouble with the logic/coding to get rid of the rows and columns that I don't need. Also, I'm not sure how to handle a row that has a cell with a comma seperated list of values that will need to be split into individual rows.

I want to compare two objects whose type may be diffrent.
For eg, I expects 'true' for comparing 1000.0(Decimal) with 1000(Double) . Similary, it should return true if I compare 10(string) and 10(double) .
I tried to compare using Object.Equals() , but it did NOT work.It return false if two objects have different data types.
Dim oldVal As Object ' assgin some value
Dim newVal As Object 'assgin some value
If Not Object.Equals(oldVal,newVal) Then

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.
