Im pretty use to doing loops (although still relative new to vb) in my code however am having difficulty setting up one that picks up an entry in one data table and then sums a field in another where records have matching criteria. Example:
[Code]...
What i am trying to do is set up a datagridview on a form that shows the summary data. The time is controlled on the form by a trackbar (output to textbox) and I started setting up a loop using (For/Next) to isolate firstly the matching entries in field 3 (time). This works fine. I then used compute to sum the the field 2. However what i want to do is to loop through table 2 and where entries match i.e. where Field 1 in table 2="A" sum matching entries in table 1 where the DateTime matches.

View 3 RepliesI have this VB.Net 1.1 project that I have to make some changes to. There is a flag in the App.config file. If it is false, the page just loads a splash screen and runs the program normally. If it is true it first opens a login window. VB.Net is not something I've ever worked with before. I can't for the life of me figure out where the logic for the picking the startup object is. In the property pages, Main.vb is always set as the startup object, but that's not even the window that loads up when the flag is false, it always comes after the splash screen.

View 1 RepliesI have made my application to start automaticly when windows start (registry ../currentversion/run/appname + path). In this mode the application start minimized and an little icon appear in the notification icon area. With this icon you can maximize the app or exit it.If you exit the app and start it again using the Menu (Start/programs etc) than the application start in minimized mode (and in this case I would like to have it in normal mode) because the setting autostart is still true.Is there a way you can detect when the application start when windows startup using the above registry or when people click on an icon in the programs menu (or desktop)?

I am trying to create a lotto simulation, but don't know how to continue.I am using numericupdowns to allow users to select 6 lotto numbers. and labels to display what they have chosen, but i'm not sure how to prevent duplicates without creating a large number of If statementsMy question is, is there an easier way to prevent duplicates without writing a bunch of if statements?here is my code:
Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim Lotto1, Lotto2, Lotto3, Lotto4, Lotto5, Lotto6 As Single Lotto1 = Val(NumericUpDown1.Text) lblLotto1.Text = Lotto1 Lotto2 = Val(NumericUpDown2.Text) lblLotto2.Text = Lotto2 Lotto3 = Val(NumericUpDown3.Text)
[code]....
I don't understand how to save the user selected numbers, let the computer generate 6 random numbers, and match the two sets of numbers together to see how many matches there are. As far as I understand the numbers should be stored in 2 separate arrays and then matched together to find any matches.

I am attempting to create a program which saves customer information for a business e.g first name, last name, address etc. but i am having trouble coding the save , new, print, next/previous record buttons.
Would someone be able to link me to a tutorial which explains how to do these?
I've done some research into this using the MSD website; I have found that my applicaiton saves the Customer Details to the Customer File, but only as (spaces). No data is present in the file.
I'm creating an application that saves Customer data to a file. Once the Data is saved into the file, how would i then get it from the file into a ListView?

I'm new to using httpwebrequest i've always just used webbrower controls but want to get away from doing that for obvious reason with that said.
I'm having it go to a wepage there is no login what so ever. but there is a cookie that holds saved data from the page. when in IE or any other brower you click an option from a combo box and it reloads the page and saves that data to a cookie.
CODE:
if you just do a httpwebrrquest it goes to 1 - Home what i'm trying to do is get to 25 - Page2 the cookie has the Sid number i'm been searching and reading for atleast 10hrs now and not even close to anywhere farther than i was. if i used Webbrowser it would just save the cookie for me automaticly but want to get away from hearing the clicking and wasting time of downloading all the pictures and stuff.
Basically I have a simple while loop that loops through a datareader and saves the information into a object collection. Later on in the code I have a simple function that loops through the collection and exports the data to excel. The later part works flawlessly.OK the issue is that for some strange issue If I just let the while loop work as it should it misses records in the datareader stream. Now it sounds crazy but if i add a counter (x=x+1) along with a message box at the end of the loop to tell me the value of the counter (msgbox(x)) it ALWAYS saves the correct amount of records. If I take the msgbox line out it ALWAYS misses records. I am so boggled right now.[code].....
