View 2 RepliesRefer To A Parent Window From A Child?
Mar 4, 2010I'm working on a sdi-like WPF application with VB as the code behind. Basically, I have a main window that has some tabs and a button that opens (shows) another child window. I need that child window to refer back to the parent main window and automatically bring it in focus and have a specific tab selected (via a button on that child). The child window is a separate class file with its own xaml and VB code in my project.In the child I tried using
My.Windows.MainWindow.myTabControl.ItemSelected = My.Windows.MainWindow.tabIWantSelected
My.Windows.MainWindow.Focus()
but this does not appear to work as the main window in the background doesn't appear to be referenced in this way. I can use My.[bla bla].Show() - but that creates a whole new instance of the main window on top of the old one. Activate() doesn't work either since the main window is already activated.It seems like a simple task but am I forced to use something like SetForegroundWindow()?

Storing Parameters From File Into Custom Class
Oct 4, 2010I'm trying to create a program that will read in a custom file similar to a config/INI file and parse the data and store them into variables of a custom class. Essentially I want to be able to read in line by line, split the line by the space and then store the value into a class object's variable with the same name.
For example, I have a class called body.
Public Class body
Dim height As Double
Dim weight As Double
End Class
Avoid Closing Of A Custom Combo Box Popup Window In A Custom Datagrid?
Jan 31, 2012I was trying to block the closing of a custom combo box popup window in my custom DataGrid. The popup window comes by pressing F4 or ALT+DOWN keys in my datagrid which is getting closed if I press the down arrow for the first time, after showing the first value in the combo box as selected. Next time onwards, if I press the F4 key and down arrow, I can move to any item in the popup window and select the item using keyboard and in that case, the popup window is not getting closed till I press the ENTER key or selection using the Mouse. Is there any specific reason for this behaviour or something is missing in my code part? [code]...

Interface And Graphics :: Making A Custom Class That Mocks The System.Drawing.Rectangle Class?
Jul 6, 2010I'm making a custom class that mocks the System.Drawing.Rectangle class because the Rectangle class doesn't have a name property.

So I changed the _onPaint event but nothing is working out when I run the program?

Aug 22, 2011I know how to use the <include> keyword from my code to refer to a member in an external comments file. Something like: <include file="Comments.xml" path="Docs/ClassName/Members[@name='DoIt']/*" /> However, I have members in the Comments.xml file which are repeated that I would like to split out and refer to within the Comments.xml file itself. As an example, it could be an argument definition that is used multiple time. I've tried the same format as above, but it doesn't work.

View 9 RepliesCustom Window Resize And Relocate
Apr 4, 2012How would I re-size the window @ a point relative to its parent location and size. I am using code from Make an unowned window's parent to my form, to be able to set a windows parent to panel1.
Dim proc As Process
' Start the process
proc = Process.Start("C:UsersDmitryAppDataRoamingSpotifyspotify.exe")
proc.WaitForInputIdle()
Dim tmp_hWnd As IntPtr

This works on most windows except for ones that are customized. Maximizing the window will maximize the window to bounds of the actual screen bounds instead of the panel1 bounds. Code works fine with normal windows but not with this one. (Spotify Window.)

Feb 28, 2012I have a custom WPF window defined as:
<Window x:Class="MainWindow"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" MinHeight="300" Height="350" MinWidth="600" Width="700" ResizeMode="CanResizeWithGrip" AllowsTransparency="True" WindowStyle="None">
I found a class online that creates drop shadows, shown below. This works well, even with a resize grip, until I maximise the window. Once I maximise the window or change the window state of another window (eg. Visual Studio), I loose the drop shadow and I cannot get it back.

.net - WP7 Custom Class UI Binding?
Feb 4, 2011I have a map with a MapItemsControl in my WP7 app that contains pushpins bound to items in a collection of custom classes. The pushpins are bound to properties of the item in the collection via a DataTemplate.When an item is added to or removed from the collection, all pins display correctly, with properties as per bindings, but when just an items' properties are modified, the UI does not update. The bindings just seem to get values from the source item upon loading, but I'd like them to keep the UI elements updated when the source collection items' properties are updated.To illustrate, I'll create a similar example:
Heres a custom class:
Public Class Box
Property CurrentColor As Color
Property Location As GeoCoordinate
End Class
[code]....
Whenever I add or remove items from TempBoxes, the pins all render as they should (e.g. if I specify a color in the collection item, the pin shows the color).Tapping on the item triggers the BoxTouched sub, which causes the item's color to change in the collection, but the UI doesn't change (pin color stays the same).To get the UI to update the color, I have to get it to render the pins again, by adding something like this to BoxTouched:
BoxControl.ItemsSource = Nothing
BoxControl.ItemsSource = TempBoxes

View 2 RepliesUsing A Custom Class In HashSet
May 30, 2010I created a custom class which just stores 3 byte values, (R G B to be exact), which constantly change. So my idea was to store that class in a HashSet, then create a new instance of the class (with different byte values) then add that to the HashSet. There can be duplicates, which is why I decided to use a HashSet, which will ignore an item if it's allready been added. Doing this on a List would be too slow.But I've ran into a problem. Adding a custom class to hashset seems to only allow 1 to be added. I assume this is because its hashing the class object while ignoring the data (byte rgb values) it contains? Is there a way around this? It's possible to convert the RGB to Color and just use that in the HashSet, but conversion is a bit too slow.
