VS 2008 How do I clear the listbox in Visual Basic?
View 2 RepliesI 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.

How to display zeros after decimal place in numbers in Listbox?
View 3 Replieshow to make a listbox change the selected item to the next or previous item by using a button... I want to have up/down buttons.
View 2 Repliesso basically, (pretty simple) I have this listbox, filled with items like
(eg.)
Billy Bob
Jerry
Jo-Shmo
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?
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.
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)

View 9 RepliesDoes anybody know which version of Visual Studio 2010 contains the full set of Visual Basic SharePoint Templates? I am about to embark on a project to create Visual Web Parts to be used in a SharePoint report.
At the moment I am using Visual Studio 2008 and even though the WSPBuilder is installed none of the relevant SharePoint templates are present.Having searched SO and the web, most advise to install the templates via the Visual Studio command prompt: devenv /installvstemplates
Alas the Visual Studio command prompt is also missing from my VS2008 installation.So, the question remains: which version of VS2010 contains what I need for pain-free SharePoint development? There is a rather large price different between VS2010 Professional and VS2010 Premium, so can anyone tell me if the cheaper version (VS2010 Professional) contains all the Sharepoint templates?

I have Visual Studio 2008 Professional and I'm trying to make it so I can click a button to send the application to the System Tray and then click the icon in the System Tray to make the application come back.
Can anyone provide me a method or sample code to do this?
when the user clicks on the add button another form launches, which enables the user to add student info such as name, address, course, start date and end date, this information is then written to class when the ok button on that form is clicked, and then displays the data on the initial form in data grid. the user can add multiple entries and they are all displayed on the intial form and a the data grid is populatedwhen any of the rows in the displayed grid is selected, and the update button is clicked then the same form launches as the previous one and but this time its in the update mode and pre populates the form with the inital values.
