Everything in my program is working correctly so far. The only problem I have is trying to update my totals for the program. I need to show total sales, total pay, and total commission for the program by using the file and then summary key. How the program works is that you get a base pay of $250 and you get a commission rate of .15 if you reach 1000 sales. I have done running totals before but not for one with multiple functions.
Option Strict On
Public Class CommissionForm
Const QuotaInteger As Integer = 1000
Const BASEPAYInteger As Integer = 250
Const COMMISSIONRATEDecimal As Decimal = 0.15D

This is my first post on this forum, so please excuse me if I'm posting wrong. Anyway, I've been having an issue that I've never seen before and is driving me nut, I have a windows form on which I have placed many textboxes that display information from a MS SQL database. The user can then change these values and hit a "save" button which writes the changes to the database. I also have certain textboxes that with the "on leave" event (after a user enters a possible new value) trigger a method that recalculates some of the other fields based on the new information. Hopefully that all makes sense.
So the problem is, when I run through this "recalc" method the first time around, it doesn't update those textboxes that it's supposed to. However, when I put a breakpoint in and debug through it, the debugger shows it putting in the correct values into the textboxes. It's just as soon as the method is done, it puts them back to blank, or whatever they were before
'Rebind stuff here
lblCabinets.Text = curMfg.ToString("c")
txtCabinets.Text = curMfg.ToString("c")

I am running a test program for VB.NET, and it will simply crunch a million numbers in for loop. I've linked a variable implying the progress of the for loop with the progress bar, but it seems that when I run the program, the progress bar does not update itself. The bar itself has only value 0-100 as input (as stated in the document) and I've tested it without using the for loop, and it works.

I wrote this VB program to be able to throw a device we developed into programming mode where we use an ATMEL Flip installer to upload new firmware. I can program one device after another running the application off of Visual Studio Express 2010 or Visual Studio 2010, but when I go to publish this file and run it on another machine, it becomes unstable and crashes after each upload. On those same computers if I run the raw unpackaged program under Visual Studio Express, the system does not crash, and I can program devices repeatedly.

I have a VB.NET 2010 app that uses a backgroundworker to process MS Word docs. All of the code does what it is supposed to do, except when my code calls ReportProgress(). The UI cannot process the ProgressChanged event fast enough before the values in the class that are passed are changed. I know this because I inserted a System.Threading.Thread.Sleep(100) line after each ReportProgress() call which allows time for the UI to make the updates properly. I guess I am looking for a better solution thanThread.Sleep(100) since this adds to the amount of time it takes to process all of the files. Here are some snippets of code that I am using:

i have 2 queries in vb.net with an if clause -
if x=0 then
insert into table1
else
update table1
both queries have 5 fields. now what i want to do is after this insert or update takes place, i need to look at this inserted/updated record and compare it with another table (table2). Especially for update, i have 5 fields in both tables. if any of the 5 fields dont match with table2, then i insert a new record in table 2 which is the updated record in table 1.
