Maximising Window List Item?
May 18, 2010
I have a standard MDIWindowListItem that selects child forms correctly but I really want it to maximise the selected form if it is currently minimised. Can't find any event that triggers when a form name is clicked so I can determine the child form selected.VS2005 or 2008
Update:Fiddling about I did find a collection MenuStrip1.MdiWindowListItem.DropDownItems and one can use .text to get the form caption which I could use if I knew the item selected.

I have a list box on the form which functions as a copy/paste. When you copy something, it is automatically added to the list box as a "clipboard helper". Here is the problem,however: if the text is more than 1 line, the list box does not show all the text.It ends up looking messy.So getting back to my question, is it possible to make the list box item height for an item depending on the amount of lines that item contains?This is a one line sentence in the list box and should take up one line.This is a multi line sentence in the list box and should take up two lines for item height.

I'm having some difficulty with a sorted & grouped listbox in WPF vb.net 3.5 that has an items source bound to an ObservableCollection.
What I want to be able to do is to retrieve a piece of data from the ObservableCollection items source depending on what item in the listbox the user has selected.I've almost got it working but because the listbox is sorted it does not match the index of the items source.
[code]...
As I previously mentioned, because the lstBox is sorted and also grouped the index's don't match up.Does anyone know how I can get the correct information I want from the List Source depending on the selected item in the list box?

How someone would select an item from a list box and click a button and have that item go into another listbox with it's price? I seem to be stuck on this part.
Here's my code:
I want to select the first option from the first listbox and I want to put it into another listbox along with the price of that item on the same line in the listbox. I can't seem to figure out how to that.
Public Class Form1
Const dcmPRICE_STRESS As Decimal = CDec(595.0)
Const dcmPRICE_TIME_MANAGMENT As Decimal = 695

my program downloads into a combobox every item(line) that is in a text file located on a server.
Every line in the text file ends with "a)" or with "g)".
Now I just want to make 3 radio buttons:
- one that will allow the download in the combobox only the item ending with "g)"
- one that will allow the download in the combobox only the item ending with "a)"
- one that will allow the download in the combobox of both (I already know how to do).
How can I do so?
To download the entire list in the combobox I do:
Dim List As String = client.DownloadString("http://mywebsite.com/mytextfile.txt)Dim lines As String() = List.Split(New String() {ControlChars.CrLf}, StringSplitOptions.RemoveEmptyEntries)ComboBox1.Items.Clear()
ComboBox1.Items.AddRange(lines)

I have a List myList of MyObjects. Is it possible to check if myList contains a particular myObject based on a property of myObject in VB.NET? In C#, you'd something similar to this right:
myList.Exists(myObject => myObject.property1 == 3)

I have a List(Of MyObj), and I want to iterate through that list and compare each element to all other elements in the same list, excluding (if possible) the same element. I have a solution that works, but it's slow and uses double For loops. It may possibly have also summoned Cthulhu from his sleep. This below is a sanitized version of what I have:
Dim MyList As New List(Of MyObj)({Obj1, Obj2, Obj3, Obj4, Obj5, Obj6})
If MyList.Count > 0 Then
For i = 0 To (MyList.Count - 1) Step 1

I want to know how to test the 1st list box if it has items more than the other list box but by one item, here is what i have: If lstInvisibleTv. Items.Count > lstInvisiblePc.Items.Count Then it works good if the lstInvisibleTv list box is greater than the other list box by one but it also works if it is greater the other one by one or more which I do not want. I want it to work just by one.

I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?

I can not use Inheritance Picker Dialog windows. Choosing Project in menu bar and then Add New Item, there is Templates frame only and Inherited Form is missing. Categories frame, which should be located on the left side, is missing as well. So i could not choose Windows Forms from Categories Frame on the left and Inherited Form from Templates on the right. Is it possible that Express Edition does not support Inheritance?

I'm trying to drag a listitem from a listbox onto a picture box. The list item is a persons name. The value member of the list item is the ID of the people listed. When I drop the list item onto the picture box I want to use the persons ID to query a photo and load that photo. I can't seem to access the value though, only the name text, using e.Data.GetDataPresent where e is the DragEventArgs. Could someone point me in the right direction?

I am making a password-storage application on Visual Basic (2008). I need to know how, when you add a list item (which I already know how to do), to also specify a password to go with it. Then when you select it on the listbox it displays the password.I am using these codes right now but it crashes...
Code:
Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
MsgBox(password(ListBox1.SelectedIndex))

I'm sure I read somewhere that this is possible. Is it possible to add an item to the start of a list rather than at the end? And of course, I'd want it to push all the other list items down, not just over-write the first item. Is that possible?

I wish to create a drop-down list box with items in it. Easy to do and done that. What I also wish to to is assign a numerical value to each list item. I believe under VB6 is was done using the list's `Value` property to set and get the item. It's so I can write a one byte value to a file but display a text value on the form. Don't wish to mess wish classes and arrays, but if I have to I guess it'll be have to be done.Was looking at some examples of making in-memory arrays/datasets for a list-box but just sees like a programming overkill for the simple thing I wish to do.Put it another way....
List box item 1 = "First option". List box value 1 = 35
List box item 1 = "Second option". List box value 1 = 44
List box item 1 = "Third option". List box value 1 = 3
If the user selects "Second item" from the drop down list box then that property do I use to retrieve that list item's value `44`. Also, when I pprogramatically populate the drop-down list, how to I set each lite item's `Value` property accordingly. As in the example 35, 44 and 3 Tried using `SelectedItem` and `SelectedValue`?

I have two lists with strings as follows
list1=[Information,want,wall,east]
list2=[castle,information,want,wall,fortification]
List 2 is bigger than list 1. I am trying to compare each item of the list with each other as follows. The problem is that not all items are compared since Index1 <> list1.count. If I take this out I am getting an error ("index our of range").
For index1 As Integer = 0 To list2.Count - 1
If index1 <> list1.Count Then
if list1.item(index1) <> list2.item(index2) then

i have a sub that checks all drives on a computer;
Dim getInfo As System.IO.DriveInfo()
getInfo = System.IO.DriveInfo.GetDrives
For Each info As System.IO.DriveInfo In getInfo
TextBox1.Text = TextBox1.Text & info.Name & vbCrLf
Next
this shows all drives in textbox1. now if i select the drive i want, i can then check the free & total space with this sub;
Dim cdrive As System.IO.DriveInfo
cdrive = My.Computer.FileSystem.GetDriveInfo(TextBox1.SelectedText)
TextBox2.Text = TextBox1.SelectedText & " has " & cdrive.TotalSize / 1024 / 1024 / 1024 & "gb total space" & vbCrLf
TextBox2.Text = TextBox2.Text & "and " & cdrive.TotalFreeSpace / 1024 / 1024 / 1024 & "gb free space"
all this is good if i select the drive i want to check. but if i only click the drive, since no text is selected, the second sub does not work.is there a way to check at which index the cursor is, grab the item of the index, and pass it to the sub so i don't have to select the text itself?

Sorting arrays are useful when you want to get the first/last/min/max logical item of a list. I.E. A list that contains numbers and you want to find the Min/Max (without LINQ), you can sort the list and pull the first/last element. It's also useful to display lists to the user in alphabetical order.
