Mar 16, 2010
I am working on a windows form project and having some problem with UserControl Double Buffering.I created a usercontrol and has a background image, then on top of it I have few radio buttons and labels. Radio buttons and labels are all having transparent background as color.However, when I show and hide the User control, I can see the flickering on those labels and radio buttons that has transparent background.And I tried
Me.SetStyle(ControlStyles.DoubleBuffer _
Or ControlStyles.AllPaintingInWmPaint _
Or ControlStyles.UserPaint _

I have a usercontrol with a picturebox and a few buttons related to it, such as LoadFromFile, Paste and Zoom (that last one pops up a new form). Is there a way to override the basic Enabled property of the usercontrol so that I can keep the Zoom button active all the time, while turning off the other buttons?
I realize there are 2 "obvious" replies. don't do Enabled=False, create a custom method. do everything in the one form, not a usercontrol, so you can pick and choose disabling. Both are less than ideal, given that I'm putting this control into a couple of existing forms, so I'd like to work around how those forms already behave. So is there a way to override the behavior of my usercontrol when it gets disabled? What would be my best strategy?

I have a question about the webbrowser control that I hope someone can answer. I am working on a document retrieval and storing class that uses HTML to display and save data. I want to use the webbrowser control in winforms using VB.Net. I only want to store the fields values in the html document, not the whole document. I am hoping to use labels in html and read them with the DOM of the web browser control but am not sure how to do this.
Has anyone done this before and could someone please provide some sample code on how to do this?

There is a panel which contains 2 components: a label and a TreeView. The hierarchy, obviously, looks like this:panel1 // handles Enter event
- label1
- treeView1
I need to do some UI updates when user starts interacting with any of these 3 controls. My attempted strategy was to catch the Enter event of the panel, which would fire when user clicks a label, or TreeView. This way, I can write only one (1) event handler instead of several. While it worked for the TreeView, it didn't work for the label. When I click the label, I don't get the Enter event on the panel. Whats different about the label control? I could handle the Click event of the label. At the same time, I wonder what the other solutions might be.

what I am trying to accomplish worked with the code in the last thread I posted a while back. I still am using this code, however, I changed the window size to work better and gave it a nicer background for the title screen of my project. Now what I am working on at the moment is making a settings form that has 2 labels. One for "Default" Layout and one for "Plain" layout. When default is at start, the default label is disabled,and when plain layout is clicked, the button is disabled and default button is enabled.Basically, this is a toggle switch for default or plain where if one is enabled, the option for it is disabled and the other is enabled.My problem is that when I switch from Plain back to default, the background Image will not switch back from the plain background color of "control"Here is my code:
Public Class Settings
Private Sub LinkLabel1_LinkClicked(ByVal sender As System.Object, ByVal e As System.Windows.Forms.LinkLabelLinkClickedEventArgs) Handles LinkLabel1.LinkClicked
MiDNiGHT.BackgroundImage = Nothing[code].......

I am building a application in VB 2010 Express, that tracks sales leads, I have everything working except 1 last item. I want the users to be able to select a different background image to match their industry. I have all the images embedded, but can't figure out how to allow the user to select.
Preference is to have a separate form for the user to cheese on launch, but I am OK with it just being a dropdown in the lower left corner of the app.

I am already familliar with applying an image to a form background. My application has many in it, but I want to give the user the option of browsing for an image of their own to apply to a form. I don't intend to save the images as defaults or anything. Just the option to browse and apply to a form.

i'm currently wonder how to let the users change the font size via a combo box(I have it set up for Small,Medium and Large) That should be fairly easy. The next is more complex. I want users to be able to browse for an image and use it as the background image of the program.

I'm trying to allow scrolling in a Multiline-TextBox even if the TextBox is set to
textbox.Enabled = False
This is not possible, as the Scrollbar is disabled with the Enabled-Command, too.The default solution here is to set
textbox.ReadOnly = True
textbox.Enabled = True
but this doesn't really do the trick for me. With ReadOnly I can still select the text of a TextBox as well as place the cursor inside of it. But as I have normal (non Multiline-TextBoxes) and other controls on the same form I don't want that to happen. I want to have exactly the same behavior as all the other disabled TextBoxes.
For everything else, like mimic the color of a disabled textbox and so on, there is a legitimate workaround with the ReadOnly-Property, but I coudn't find any for selecting text and placing the cursor.
UPDATE:I tried to use WIN32 API but it didn't work as expected:
Imports System.Windows.Forms
Imports System.Runtime.InteropServices
Public Class TestTextBox

I'm trying to create a button that will hide the panel that I have docked at the centre of my user control. [code]This works to an extent. However, when the bottomPanel is set to Fill it seems to fill the entire control, and not just up to toolStrip1. Can anyone tell me why this is happening, and how to correct it?

I'm trying to bind a WinForms TreeView control to some user-defined objects. In particular, I'd like to bind aTreeNode.Text property to myObject.Name. My strategy is to create xTreeNode, a subclass of TreeNode, add a DataBindings collection, and expose its Text property. This would allow me to write some code like this:
Dim oBinding as Binding
Dim bs as New BindingSource
bs.DataSource = myObj

I have already posted this question on the "reporting services" forum and received no responses, so i thought i'd give it a try here.
SQL server 2005 SP3, VS 2005, vb.net, RV control.
When i add a background image to the page header, body and page footer, The rendering takes about one second per page. Without the background images, it renders about 25-50 pages per second. My report is a statement print report and has about 1500 pages.
Since it is the same image on each page, why does the server need to send that image over and over again to the report viewer control?
In vb.net i have the Report Viewer control and i bring up a report in normal viewing mode. when i click on the print layout mode, or have that mode set up to be the default mode, It takes forever when i have a background image and virtually no time for the same report without the images. The images are gifs about 5 or 6k each. I have chosen to embed the image into the report.
How do i optimize the usage of background images so they do not interfere with the rendering speed? Or at least minimalize the slowdown.
[EDIT:] I have discovered that if i render it to PDF and open the PDF and page through the report, it is much much faster. In other words if i choose to render to 'printlayout', it is say 25 times slower than when i render it to default, and about 20 times slower then if i render it to PDF. And the PDF contains exact rendering for all pages, exactly the same rendering as the print layout mode generates.

I'm dynamically creating a button control, and I'd like to add a background image from my resources thing to the button.
Now, I'm pretty sure it would be:

But I don't know how to refer to an image that is in my project resources.
I've tried:
CODE:
But that gives error:Value of type 'System.Drawing.Bitmap' cannot be converted to 'String'.

In my project, I have a form with a background pic that I like, but unfortunately, I also have a ListView on that form which covers most of the picture. Now, is there a way to find the part of the background image concealed by the ListView, and then display it as a background image of the ListView at decreased opacity? You know, like a vague image.Just one more thing, setting the form's transparency key to the background color of the ListView is not an option.

I am attempting to write a simple 11ball style game. It requires images of poolballs overlapping each other. Since the balls will need some internal intelligence I was hoping to create them as usercontrols.I am having trouble gettiing the control's background to be transparent.Setting the background color to (Web) transparent only makes the background clone the form background color.

I have a UserControl that contains other controls that I would like to be able to rearrange or resize at design time. So I have a custom designer for the UserControl that inherits from System.Windows.Forms.Design.ParentControlDesigner, and I call EnableDesignMode on the child controls from within the designer. That way, at design time, I can drag and drop the child controls to move them, or resize them. But I can also drag and drop the child controls somewhere else on the form that is outside of the original UserControl. Is there a way I can limit the child controls from being moved or resized outside the UserControl?

I am trying to create a custom control using vb.net.I have added a image to the user control and the problem I am having is that when I resize the image, the image seems to move as well.I want to be able to resize the user control height without moving the image on the user control.
everytime I resize the user control, it seems to move the image on it as well.Is there a way of leaving the image where it is without moving it as the user control moves?
