Designing A Program - Click On Something In The List It Will Automatically Open A .dat File Pull The Information
Jan 28, 2011
Im using visual basic 2010 and im building a program that will basically, you click on something in the list it will automatically open a .dat file pull the information that it needs, and then proceed to enter it into a box on the right. Well heres my issue i know how to do everything else but i cant seem to imitate this image, i need to know how i can make a list like this where the whole row is selectable, and the items/subitems are divided.
I am having trouble with this list box assignment. I am supposed to pull the information from a text file in the debug folder. The problem is the code looks perfect to me, but when I debug, the first line that starts with : lstSummary.items.add returns as being in the wrong format. The code is below.
Private Sub btnSummary_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSummary.Click Dim strAccount As String
I created a webrowser in VB.net to track employee usage and it seems to be working fine but I wanted to find out what it would take to set this as a default browser on a PC.I also would need to know how to pull the URL from shortcuts so when the program opens I can have it open to the URL in the shortcut.
I've used Visual Basic on and off for years, but for some reason this has never crossed my path, though it's probably relatively simple.
I have a program which runs in the background, in the System Tray. (Which is to say it has a NotifyIcon and is Hiding.) Using the Registy, I've added a new item to the right-click menu for certain files (for example PDF) which reads "Accept".
The goal is to have this open the file in my program and have it run the script. The script itself works flawlessly with an Open Dialog box - all it does is change the "comments" on the file. But I can't for the life of me figure out how to do it without the dialog box.
The program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage. The issue is as my code hits PageLoadStage of "2" and runs the QueryDatabase() Function i am encountering an error of: "OleDB exception unhandled: No value given for one or more of the required parameters." This occurs on line 15 of the first code snippet. Can anyone explain this and/or identify any code issues if that is the cause.

Anyway, I'm a teacher and am writing a program that simply shows kids a word on a flashcard. There are 2 buttons, 1 to read the word and 1 to go to a new work. There are going to be 300 words. Really I'm just testing it right here. What I want to know is should I be inputting all the words right into the code like I did with "hi" and "not 1" (Don't ask. those are just the 2 random words I picked to test this out with). OR is there a better way (maybe somehow to type all the words on a text file and have the program randomly pull one of them (I don't know how to do this).
Here is the code so far:
Public Class Form1 Dim word Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
I am creating a medical record system using MS Access 2007. the finish product will be used for a small healthcare which has only one available pc for now i ve done all required tables and some queries. What I really want to do is to design the forms where user can access information using VB 2010. I ve read tutorials online about how to connect dataabase to vb and successfully did that.
I have an assignment where I have to design an information retrevial system for estate agents. I have to be able to view the houses for sale, and delete them when there sold. I am new to vb script: Opens the Policy Details file and reads in the '== records into the arrays (parameters) which are '== passed back to the calling routine for '== processing. '== N.B.

Let's say my browser goes to a page similar to this one below ..
Picture Is Here
On this page there is a hyper link called 'Click Here' .. when I click it, it opens another window with things in it.
How can I click this hyper link in vb.net automatically without me clicking on it with the mouse, and how do I open the window in a second web browser ?
We can assume that the first browser is called (WebBroswer1 ) and the second one is called (WebBrower2).
I know how to perform buttons clicks and do raise the 'OnClick' Events, but I don't know how to do it with a hyper links.
I'm trying to pull information from an XML webpage but for some reason it just isn't working. The XML webpage looks a little like
<?xml version="1.0" encoding="UTF-8"?> <item> <reqdat>Date and time</reqdate> <result>Completed</result> </item>
I want to get the node, but everything I've tried hasn't worked :( I think what I need to do might have something to do with SelectSingleNode but I'm not sure.
I have code which saves DGV contents including check box columns as a comma separated text file. I also have correct code which will take the text file and re-insert it into the DGV at a later time. This all works.When I'm working on the DGV, I have this
Private Sub DataGridView1_CellValueChanged(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellValueChanged If DataGridView1.Columns(e.ColumnIndex).Name = "Column12" Then[code]....
So that when the check box is true, columns 1 and 3 turn different colours, and when false, go to a yellow colour.However, when I "re-insert" my DGV info from my text file, the check boxes come back correctly - as true and false on the right rows - but columns 1 and 3 don't change colour. I've tried a "DataGridView1.Refresh" option but not getting it to work.The DGV is unbound. I need it to recognise which check boxes are true and update automatically when the information is opened from a text file.

I started making a program, and I wanted to insert music to play. i just added music to the resources and used the code my.computer.audio.play(my.resources.name_of_the_file and so on. this worked perfectly until I added the 5th song. the resource file became to large and vb said it was corrupt. so I thought of a new way: making a music file opener. I made a code so a window opens where you can select your .wav files. that all worked, but I couldn't get it so the music would start automaticly or that it would actually play. this is the code I have so far:
vb.net Dim Open As New OpenFileDialog() Open.Filter = "Wav [*.wav*]|*.wav" Open.CheckFileExists = True
[Code]....
as you can see I put stars in the place where I have no idea what I have to do next. I e.g. tried my.computer and a path

How can I make a program so you click a button and select a File using a OpenFileDialog and click send on your computer and it will send the file to a different computer and then a SaveFileDialog will show asking where to save the file on the other computer. Oh ya I cant use WinSock or whatever becuase im using Windows Vista 64 Bit. I need it because I for some reason cant use printer sharing. It might be because im on A 64bit Vista Machine and I want to print a file off of a 32bit XP Home Machine.
