View 4 RepliesDeclare "custom Command" In Visual Basic 2010?
Jan 13, 2011I'd like to, let say "declare" my custom command, and what do I mean by command is something you type in the code, when for example you click a button. Just like Textbox (for example), my custom command sould have "underthings" in it, so just like I can type in Textbox1.Text. And that underthing (in this example, textbox is my custom command and .text is a sub/underthing) I can set if it is a boolean or string etc. I need this for my login program, where that custom command is an username (named username, what you can dim), and then it has sub things, like username1.email (string for e-mail text) and username1.password, username1.ismoderator (boolean, true or false). So an example, in my program I can do like this:
'Username is my custom command, just I don't know how to'define or declare it.'Username has here, to keep it simple, 2 sub things, it is'username.password and username.name Private Sub btn_registrate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_registrate.Click'When the button called registrate (make new username) is clicked Dim username1 As Username'(I don't know if it must be dim blabla as NEW or without new with'my custom command)username1.name = Textbox1.Text 'Textbox for username username1.password = Textbox2.Text 'Textbox for password

Compare The Value Of Two/multi Column Array And Add Into Listbox Without Duplication In Visual Basic?
May 2, 2012I'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.
Visual Basic 2008: Reading From Textfile Into Array And Then Presented In Listbox?
Jan 7, 2012I'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)

Jun 4, 2011I am making a TabStrip control to hold a number of tabs just like TabControl, but only with the tabs, no page. The control has a "Tabs Collection", which stores a list of "Tab" class. "Tab" is not inherited from Control, but each tab has its events.

View 9 Replies.net - Which Version Of Visual Studio 2010 Contains Visual Basic SharePoint Templates
Aug 5, 2011Does 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?
