Okay, how can I 'search' and listbox item containing 'Bob', like I click a button on a form with the listbox presented, and then it auto-selects the one that contains bob? HOW COULD I DO THAT?

Clear Text Fields In Visual Basic Web Developer

Apr 7, 2012

I have a web page that has a few text fields, and a reset and submit button. I'm having trouble getting the reset button to work to clear the text fields because the required field validators and regular expression validators are blocking any code in the reset button's click event from occurring. how to get the validators to not activate when the reset button is clicked? One method I tried was to set the enabled property of all the validators to false in the reset button's code block but no luck.

Visual Basic 2008: Reading From Textfile Into Array And Then Presented In Listbox?

Jan 7, 2012

I've got the following txt file:

[code]...

Now I want that presented in the listbox with the semicolon and it should be aligned per column so that the numbers, the names, the prices and the quantity are exactly aligned per column.If I read the file like this:

[code]...

Then the semicolon is not presented in the listbox and I don't have any alignment per column. As the names of the woods are not equally long the prices and the quantity are not aligned directly below each other...

My questions are:

1) How to add the semicolon in the listbox as seperator of the columns

2) How to align the 4 columns in the listbox (as I have an array Item(3) )

Later on I need to be able to change the quantity (last column) from 0 to > 0 (that's why I have to use an array)

Compare The Value Of Two/multi Column Array And Add Into Listbox Without Duplication In Visual Basic?

May 2, 2012

I've small project to do and now I'm stuck in middle. The program is to read the sequential text file and load it into a array/array of structure.The data information is like this (sample):

ID | Name | Type
1 | Cat | Animal
2 | Dog | Animal

[code]....

This is Just as sample data, my original data is more than this.I've open the DATA.txt file using FileStreamReader:

Dim FileStreamReader As StreamReader = New StreamREader(DATA.txt)

Read all the elements in the list and pass through ReadArrayString.Split the string using:

DataString.Split(New Char() {";"c})

Pass through

ReadArrayString(0)
ReadArrayString(1)
ReadArrayString(2)

Where index 0 is the ID, index 1 is the name, and index 2 is the Type Then I load the types in the dropdown combobox menu from the array with out duplication. Like this:

If TypeComboBox.FindString(ReadArrayString(2)) < 0 Then
TypeComboBox.Items.Add(ReadArrayString(2))
End If

Now When you click TypeComboBox it will show drop down menu with following list only.

Animal
Bird
Fish

After this, when Animal type is selected/clicked from combobox dropdown menu then it should only add the Id and Name of Animal type in the ListBox.Pseudocode may looks like this:

If Animal is selected/clicked from TypeComboBox then
Add Cat into listbox
Add Dog into listbox

[code]....

I've only figure out load items from only one column/array into combobox with out duplication.But can't figure out to compare the value of one column/array with another column/array and load it into listbox. I don't want to hardcode or write matching value inside the code. What I want is use the Array.

Can't See Visual Basic Project Option In Visual Studio 2008

Jan 13, 2012

I am very new to Visual Studio Application Development. I'm mostly a DB guy. I used Visual Studio as a Report Designer, not much of an .Net guy though I can understand it. I am now asked to create a .net application and I'm trying to create a "Hello World" starter app. I opened my Visual Studio, click File-New Project and all I see is Business Intelligence Projects and Other Project Types. My step-by-step guide says choose Visual Basic, Windows Forms Application. But I can't see it as an option.

.net - Visual Basic Express 2008 Randomization?

Apr 26, 2010

I have been given a task to:Develop a program where a child will be presented with picture of a fruit (one of five possible fruit) on the screen at the click of a start button. The child will then try to recognise the fruit and write its name in a specified place on the screen. On the click of a check button the name of the fruit written by the child will be checked by your program and if correct will reward the child with a suitable message. If the name presented by the child is not correct, a suitable message should be presented on a red background with the correct name of the fruit included in the message.

so far I have managed to create a form with 5 different fruit pictures and a text box below them. a button at the bottom of the form then checks the results and presents a message box to tell them if they have passed or failed.
