View 1 RepliesI want to know how to change the form to well another screen. Example:In the popular mcdonalds flash game you can scroll through varius screens such as the restaurant, the farm, etc. You can still play the game though and it's not just a picture. Another example would be a pause/menu screen where you could interact with it. Could I use more than one form but when they play the game they can only see the first one? Then when a certain event happens it changes to the other form or something?

I have this VB.Net 1.1 project that I have to make some changes to. There is a flag in the App.config file. If it is false, the page just loads a splash screen and runs the program normally. If it is true it first opens a login window. VB.Net is not something I've ever worked with before. I can't for the life of me figure out where the logic for the picking the startup object is. In the property pages, Main.vb is always set as the startup object, but that's not even the window that loads up when the flag is false, it always comes after the splash screen.

Is it possible to programatically change the color of entire listview columns (vertical)? I know it's possible to change the color of entire rows (horizontal): ListView1.Items(priceRow).BackColor = Color.FromArgb(87, 68, 34) Changing the properties (forecolor, backcolor) in the listview collection editor did nothing.

View 2 RepliesI am making a diary Form in VB.NET to do this I am using a listview with two columns.
Column 1 consists of a list of time and column 2 is the description
Can I change the colour of certain cells in column 2 only. So when I read in the data from the database it reads in the description and then puts the data in the relevant time slot but I want the recent cells of the description column to be a different colour.
In my dialog I want to prevent the user to browse freely in certain places (this is due to the fact that my application will be running in a terminal server environment). So I want to to limit the items that will be visible in the top combobox of the server. I want it to start with "My Computer" instead of the usual "Desktop". Furthermore I only want to add mapped network drives under "My Computer" so that the user won't be able to see any local resources.With Spy++ I have been looking around at what happens when a FileDialog starts.
So far I have found that for each item in the combobox CB_SETITEMDATA and CB_INSERTSTRING methods are executed. By using a hook to the combobox I am able to intercept these messages, but sofar I am unable to determine the exact contents of what is inserted, so I am unable to determine wether it is the "Desktop" item or not.I have also discovered that the "My Computer" node is only added at the moment that the combobox is expanded. So I would need a way to get a handle to "My Computer" and insert an item for it manually
I am making a program that is in need of labels changing and showing depending on what the user clicks on a file Dialog.

How can I get items in listview? I know how to get the current item if selected but I am trying to put it in a loop where I need to get my three row items there. I have 3 columns and I want to get there items and insert it in entry string.
This code is wrong
Dim a As Integer = 0
For a = 0 To ListView1.Items.Count
columname.Text = ListView1.FocusedItem.Text(a)
columntype.Text = ListView1.Items(a).SubItems(1).Text
columnscale.Text = ListView1.SelectedItems(a).SubItems(2).Text
entry = entry + columname.Text + " " + columntype.Text + "(" + columnscale.Text + ")" + vbNewLine + "" & _
""
Next
If I look at all the options for
me.ListView1.Items(index)
one of them is for Name.
So instead of coding
Me.ListView1.Items(index)
I can use
Me.ListView1.Items("Name")
But if I go into the properties of the ListView1 and look at the collection for the Items there is no place to set the Name.I can code Me.ListView1.Items(1).Name = "Name" and then I can code Me.ListView1.Items("Name")Where can you set the "Name" of the Items in a ListView?
Can someone help me about the following code? how can i get the sum total to the label.[code]
View 12 RepliesI have an issue in a project trying to auto-scroll down a ListView (used as Details with columns) when adding a new ListViewItem when the window is minimized. I guess we have to use TopItem property to set force the listview to scroll down.I get two exceptions when the form is minimized: "Object reference not set to an instance of an object." "Index (zero based) must be greater than or equal to zero and less than the size of the argument list."
