• Arjun B Remove DVD from BindingList(Of DVD)

  Hello, I cannot figure out why this code does not work. It is supposed to remove the selected DVD from the BindingList. The code compiles it just does not function properly. Private Sub btnRemove_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRemove.Click Dim selected As DVD = CType(CollectionBindingSource.Current, DVD) Dim collection As BindingList(Of DVD) = LoadCollection() collection.Remove(selected) CollectionBindingSource.DataSource = collection End Sub Upon running a collection.Contains(selected) it says the item is not in the collection which I know to be false because it is not only being displayed in the DataGridView it is also selected and accessa ...Show All

• AlexBB maximize application up to taskbar

  Hi I have a windows form app which I maximize on startup. The bottom of the form however seems to dissapear behind the taskbar giving an unfinished affect. How can I set the form to fill the screen up to the taskbar Matt This didn't help but while making the change I thought I'd try setting topmost to true. This has corrected the display so that it fills to the taskbar. Slightly irritating in that I now have to specifically minimize the app if I want to work with something else but I can live with that. Might try turning this off programmatically after its been maximized. Thanks all for the help. Matt Does it behave correctly if you use the maximize button on the top I ...Show All

• Dave987654321 display msi path

  Hi, I want to display msi path from where it is running. For example my msi is in "c:\msifolder\test.msi".and when i click on msi.after initial dialogs,it should display "c:\msifolder\test.msi". Thanks No it won't. But why do you need that path during a repair or an uninstall If you did something during an install (like access a file at the MSI location, or copy it or something) I'm wondering why you need to do that during a repair or an uninstall. After the product has been installed, the SOURCELIST property returns a list of the locations where the original MSI can be accessed - maybe that's what you need.

• Orellang Fade

  How can I make a label "fade in" and "fade out" Preferably with a timer Thanks, as far as I can see, the Label does not have an opacity! However if it were, you can still use 1 timer to do both, fade in and then back out by checking the opacity values. For this you could use a bool value to indicate if its going to fade in or out and depending on it, fade in or out. You can use 2 timers if you wish but this is a developer preference thing. The opacity would've been a better option. Warning: lots of code ahead. To fade a label, you would just have to smoothly change from the foreground color to the background color. Doing that smoothly is not easily done by changing the RGB components of the col ...Show All

• Abraham Varghese Images do not appear in listview

  Hi all, I am using a listview and have images being shown in the first column, however these images do not show up every time.

• VioxX Buffering Images HELP

  Im not sure if this is the right place for this post, if not I apologize in advance this is my first time on the forum. My question is - I am trying to write an Image Viewer program that reads the file paths from the file system and stores them in a list. Then it loads the first 25 images into an Image list(the 25 can be set to whatever I want.). That all works fine. The problem is when you get to the end of the 25 and its time to add more images. It works but is EXTREMELY slow. I cant seem to figure this out and have been playing with it for a while now. Any insight would be appriciated. Heres my code for adding to the buffer - public void vScrollBar1_Scroll( object sender, ScrollEventArgs e) { Thread addThread; i ...Show All

• RamiEmad Keyboard cues problem

  Hello , Background: I've got a WinForms app written in C# using .Net 2.0. In this app I have a custom button class: public class ThinButton : Button The reason for having the class is to override the default painting. Specifically I want to draw a thin border and have a narrower margin between the button edge and the button text. This allows me to have a smaller button (to fit into tight places) that still looks good. The Problem: I have noticed that when I press the alt key on the keyboard (when running the app) the accelerator key mnemonics are shown underlined, as they should, for all controls, including my ThinButtons. When I press the alt key again, the mnemonics dissappear, as they should, for some control ...Show All
