I place a Background Image on my main form to a BMP file, On-top of the Background I have buttons, and Labels. When I execute the code, the labels (which are supposed to be WHITE) along with the text on the buttons is see-through, I can't get it to stay WHITE and not display whatever is behind the form. here is the examples I have, this is what it's SUPPOSED to look like: http:[url].....

I have a drop downList and I have it listing colors. When a color is selected I want to change the background color of the page itself.
I am using Visual Studio 2008 and using VB.Net.
I have created several simply custom controls and I used them in my app. Now, I changed the background color in a custom control class, because I wanted an other color for this type of control. But in my app, the background of this controls didn't change. Why? I assume, I don't need to place again this controls on each forms to get the new background color, or do I? If yes, this is very stupid in my opinion.
View 4 Replies.NET developing and have a simple question, i've been stuck on this for a while and searched many forums first with no solution so i'm posting myself. In VB for excel i've used Screenupdating=false to disable the screen updating however now i'm creating a visual studio 2010 windows forms application and its not showing up as a property. Here's the code i've tried.

I've been experimenting with background worker to maintain responsiveness and to allow the UI to update while things are being done in the background.I've been having problems getting the background worker to do anything with form controls.For simplicity lets say I have form1 and form2.The background worker is on form1Initially I couldnt get it to edit controls on form1 but by using [code]However the problem came when I tried to get the same background worker to update controls on form2, in this case a text box. With the above code there is no error but it also does not update the text box.Is there an easy way to give a background worker access to multiple forms.

View 6 RepliesI would like the main form I am designing in VB.net to appear as quickly as possible. As a result I don't want to fill a datatable in the load event but instead fill it as soon as the form appears, in the background.Then when a user clicks the button a listbox can quickly be populated.
With this in mind I called a function to fill the datable from the _Shown event. The trouble is that the form freezes until the query executes, making the process pointless for my needs.
Does anyone know how to keep the form active while the datatable fills silently in the background?
how to set the volume of the background Music that im using on my app is a bit to loud. what i really want to do is set the volume to like 50% default and have a volume level to turn it up and down this is the code im using for the BackGound Music

I have a picturebox with a pic in it, and I have a label on top of the picture.
I want the background of the the label to be transparent, so I set it's background prop to transparent and it's parent to the picturebox. I do this on form load, but for some reason the label entirely disappears once the form loads?
when I try to import an image into the forms background the form turns white ( I want another color ) and when I move controls around the pictures of the controls stay the screen. How can i fix this?

I have an app that uses transparency so that the background of the app is a custom shape. The problem I am having is the rounded corners are jagged. Not a nice clean rounded corner like you would see on an icon or widget. I have tried several different image types (i.e. PNG, GIF, etc). But it seems when I use the transparency Key the quality on the edges gets worse.

View 7 Replieson the loan of my application i created a background_worker to pre-load some of my child forms. here is the problem - it seems that the forms gets loaded into the second process and it wont have any affects on the original process .
In another words when i try to show the preloaded form nothing is displayed. How can i ask the background process to "Merge" with the main process when it is completed! i am not sure if merge is the best word to describe what i am trying to do here!!!
also if i try to re load the form that was created by the main process i will get exception saying you can't change one some that was created by another process
I was looking for a solution to run a lengthy job (looking for files on the fixed drives) withouth freezing the UI, and saw that using a BackGroundWorker control is the recommended solution.
Problem is, I don't see its ProgressChange event being triggered:

Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Button1.Enabled = False

I have got a couple of VB Powerpack Ovalshapes on my Form.I use these for a quick indication if the networked device is online or offline.I can't seem to control the Visible function (or any other function for that matter) one my Background Worker is running.For my Textboxes I used a guide by jmcilhinney which worked great for them but there is no 'Invoke' property for graphics controls.

It seems that Visual Studio is using a older verion of the System.Windows.Forms DLL.
When I instantiate a instance of the TreeNode object it doesn't have the "value" property. Right now my version of Sytem.Windows.Forms is listed as 2.0.0.0 and it's being pulled from the Microsoft.NETFrameworkv2.0.50727 folder.
I've installed all of the current .NET framework service packs....
Is there something else that I need to do so that the I load the most current version of this object?
I seem to be having a problem binding the visibility property of a textbox to a database value using the advanced binding property.
I found this article (BUG: Inconsistent behavior when you bind the Visible property of a Windows Form control to a Boolean field) stating there is a bug in some older versions of the .net framework.
Does anyone know if this has been fixed in 4.0?
