How can I update the code in KB-180736 to work in Visual Basic 2003 .Net? I don't know how to create the Delegate function for SetTime and KillTimer.

Why not just use the built-in Timers in the .NET Framework?

Actually i've checked in .Net.
However i've used below code in VB6. Please check whether this works for you.
WorkPath = App.Path
fname = "trial.csv"
Set JetConn = CreateObject("ADODB.Connection")
JetConn.Open "Provider=Microsoft.Jet.OLEDB.4.0;Extended Properties='Text';Data Source='" & WorkPath & "';"
'Open CSV file to Add/Update Master records
Set newrs = CreateObject("ADODB.Recordset")
strSQL = "SELECT * FROM " & fname
newrs.Open strSQL, JetConn, 1, 2
Regards

Is it an update query or an insert query that you have?
When you say "field", do you really mean a field, or do you mean a record? When you say that it's "empty", is it a field that is null, a field that is empty, or a record that doesn't exist?
An insert query will only add new records. An update query will only update records that exist, not create new ones. An update query will always update the values in the fields if the record exist, regardless of what the values were before.

its and update query.. and it giving me problem updating.. example.. in my project.. say i have three fields in the table..firstname, lastname, and middle name.. first name and lastname is monditary so information will always be in the table for first and last name.. and middle name might not have informaiton...
i use webmatrix to create my query and then place it in a class in my project then called it where it is needed..
problem: when i try to run an update.. if i try to update a record.. say John Brown is the person's name..if i try to change it to say..mary brown..its not updating..but if i try to change it to John James Brown..note this time, i only updated the middle name because before it didn't have one.. in this case it updates.. so i am wondering whats up with my query.. could u write me a simple update query and let me see if i can use it to test my project..becuase the generated ones not helping me..
thanks..

Here is an update query that you can use:
Dim queryString As String = "UPDATE [R_Application] SET [Fname]=@Fname, [Mname]=@Mname, [Lname]=@Lname WHERE (" & _
"[R_Application].[AppId] = @AppId)"
As you see, this is the same as you posted in your other thread. There is nothing wrong with it.
As I said in the other thread, you have to look for the error elsewhere in the code.
Debug the code and look carefully where you get the values from that you put in the parameters for the database call. I suspect that what you actually put in the parameters is the exact values that you find in the database.

I have a calculation (as can be seen below) and I want to make this number rounded to the nearest number (eg if the calc = 35.5 = 36 or 35, whichever!), how can i do this, i think the code is right, just not the right value in the round field!
'Initial Calculation
intPerc = ((intScoreTop + intScoreMid + intScoreBot + intScoreAll) * 2)
'Round int to nearest number
intPerc = Math.Round(0)

You can cast to int, or you can use Math.Ceil or Math.Floor to control the direction.

Try This, it may not be 100% correct but it should get you started:
dim original as string = ((intScoreTop + intScoreMid + intScoreBot + intScoreAll) * 2)<br />
dim determiner as string<br />
dim result as integer<br />
determiner = original.remove(0,indexof(".") + 1)<br />
determiner = determiner.remove(1,s2.length-1)<br />
<br />
if cint(s2) >= 5 then<br />
result = math.ceil(cint(s))<br />
elseif cint(s2) <5 then<br />
result = math.floor(cint(s))<br />
end if

Wow - that's really messy.

It is very interesting but what I noticed was the variables as (intscoretop, intscoremid,intscorebot and intscoreall) if you have defined these variables as INT32, it will automatically round any assigned value therefore if IntscoreTop = 35.6 will come up with 36 and no need to use math.Round function.
Math.Round function is used for double precision floating point numbers.

If the above poster assumption is correct then this it a mute point. However in your original code you were rounding zero, which should round to zero
intPerc = Math.Round(0) Math.Round takes a number and rounds it. You need to supply it with a number, in your case you did '0'. What you meant to do is:
intPerc = Math.Round(intPerc)

How can I use the barcode in my Program?
I had some question about barcode!
In my program how can I print barcode with Standard code39
If you know a free font or component and you test it please introduce me
And how can get the data from barcode reader (such as keyboard, USB, Serial-port) and display in the text box (Please give me a source not component)![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

It will depend, but most barcode readers offer an API that returns the code as a string.

yes, the most barcode writters receive an string and then generate the barcode, then only must send this control to printer, you can draw this control in a printer o another method should it work.

I suggest you to focuse on how to create and use classes in vb.net.
