Advance To Next Field After Input?
Oct 14, 2009
Ok a newbie question that I just can't find the answer to:I created a simple form with 3 textboxes and have a problem using a barcode scanner to read data in to the form. The scan gives me the correct data, but it appears in VB2008 express the CRLF get absorbed and doesn't go to the next text box. In fact hitting the enter doesn't do it either, while the tab key does.
If I scan to notepad, wordpad, etc. the CRLF causes the cursor to drop to the next line, so I know the barcode scanner is programmed correctly. What should I be looking for to have the scanned data cause focus to go tot the next textbox?

Currently on an internship from my CS degree, we have some down time and I'd like to spend it working through a series of problems (although none too large) that would advance my programming skills and allow me to dip my toes in a large breadth of different topics and areas. Unfortunately, everything I do must be done in vb.net on .net 2.0, without downloading any particular libraries.I've already worked through many of the "code-golf" tagged problems on here and the programming praxis problems posed by dailywtf.

I have written a VB.net 2010 Powerpoint addin that needs to be able to advance the slide via a button on it's main form when running the presentation. The functionality I require is exactly as if you press the space bar while focus is on the slide show window.
I have tried-PowerPointApp.ActivePresentation.SlideShowWindow.View.Next
But this does not work in excatly the same way, namely when working with several animation sequences on the same slide.I am looking into using the API - FindWindow & SendMessage but I do not fully understand the steps to get this to work, or even if it can. Or is there another way?
I am using Visual Studio 2010 RC with Powerpoint 2010 Developer Beta.

I'm working on a project where I need a timeline similar to what you would see within a video editing program. Picture of my timeline - [URL]
So far, I've designed the timeline using nested pictureboxes. The main area of the timeline is a picturebox, and each track (marker and test) are children pictureboxes contained within the first. The marker dots are custom controls that are children of the marker picturebox. The idea will be for the slider to control zooming of the information in the timeline and the scrollbar to control panning of the timeline. Live data will be added to the timeline. This live data will include the marker dots and painting on the bitmap contained within the test picturebox.
I've got portions of the timeline functioning, but I'm stuck on how I should go about panning and zooming. I would like the timeline to update every second and advance the blue bar by 1 pixel every second. The problem starts when the blue line reaches the end of the timeline. Once the blue line reaches the end, I want everything on the timeline to start scrolling off the left side. What would be the best way to go about doing this and still be able to maintain the data written to the timeline? This could be a lot of data if the program runs for several hours.

VB.NET, .NET 4
I am writing an industrial control front-end that has some "fancy" graphics to indicate the states of some machinery. For example, I indicate that some heaters are on by showing red wavy arrows emanating out from a picture of a heater. I accomplished this by creating a class that inherits from PictureBox and using a timer to advance the images:
Public Class AnimatedPictureBox
Inherits PictureBox
Private WithEvents Timer As New Timers.Timer
Public Property Interval As Double
[Code] .....
My question is "Is this an alright way to go about this or is there some obvious better way?" I'm not too good at programming and am worried that having several of these objects with their embedded timers taxing the CPU. I went with animated GIFs for some other animation stuff, but here, I wanted to be able to handle image formats that can handle a larger palette than a GIF (if that makes sense). In other words, when I tried to save some of my animations as GIFs, the image quality took an unacceptable hit.

There are lots of questions about this but I've not been able to solve my problem using the answers to any of them (after many, many attempts..)
I'm working in vb.net creating an asp.net web application. I have an SqlDataSource and a GridView on my page.
I want to change the DoNotMail boolean value represented by a Gridview checkbox and automatically update in the database if the checkbox is checked from 0 (False, Will Mail) to 1 (True, Won't Mail) here is the code I used. [code]...
is it possible to do a two way sync on the entire gridview when the user hits a button so you don't have to do an update every time a row is changed? because the user might check the box and then check another box then uncheck a box and it would be a lot of updates...

I am writing a calculator app in VB Express 2008. I'm trying to get the app to accept numeric and operator input while ignoring all the alpha input. In other words taking input from the numeric keypad and the top of the keyboard and ignoring all the letters.
Here's the block of code I have so far:
Private Sub TextBox1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
If (e.KeyCode >= Keys.D0 OrElse e.KeyCode >= Keys.NumPad0) And (e.KeyCode <= Keys.D9 OrElse e.KeyCode <= Keys.NumPad9) Then
Select Case e.KeyCode

My objective is to, instead of entering in the data manually into the text boxes, I want to read in a textfile. The Calculate button will contain the code to read in the file and assign it to the appropriate textboxes. Save the separate file in the \bin\Debug folder.
The text file just needs to have 3 integers on 3 separate lines.The code I posted works without and errors, but.I am having some trouble integrating the Stream Reader.

I cannot figure out how to incorporate the number of days into the input box then get it to loop and count the number of times the User inputs in the number of days. Then I have to incorporate it into the equation to get the total distance D = MPH * Hours. What I have right now wil not count up the number of days and locks up after I input one number and will not add anything to the listbox. Because I also have to make sure that they cant add nonnumaric values and the number of hours per day cannot exceed 20. I have put things in and taken them out but it has been 2 days and I am lost now
