how i can refresh my main form background image once a user picks a different image as the background.I have 2 forms namely Form1 (main form) and form2 from where the user can select the image he or she would like to set as the background image of form1.But the problem is that after selecting the image file from form2,when form1 is opened the background image doesnt change and remains the same as before.Only when the user ends the program and re-runs it again the image changes.
I have created a project that shows a splash screen first and then shows the main form once the main form has been fully loaded. I only want to show my splash screen once the main form has completely loaded in the background. My main form by itself takes like 3 seconds to load, so I would like to display the splash screen for about 3 seconds and then show the main form because the main form will then be fully loaded, but instead it shows the splash screen for 3 seconds and then the main form still has to load anyway.How can I load the main form in the background and then show it when it is fully loaded?
I am using background worker to report progress on the screen. In the Main.vb I have the following
Public Sub report(ByVal sender As System.Object, ByVal e As System.ComponentModel.ProgressChangedEventArgs) Handles bwlistener.ProgressChanged Dim message As String = e.UserState logRTB.AppendText(message & vbCrLf) End Sub
When I call this from Main.vb I use: bwlistener.ReportProgress(0, "Some status text goes here") It works great. The problem is when I try to call it from any other module in my project.
When I call it OtherFile.vb: Main.bwlistener.ReportProgress(0, "Some status text goes here") It doesn't work... The program doesn't crash. Debug goes through everything but no output is actually shown to the end user.
I can't remember exactly if this is possible or not but what I am attempting I would think should theoretically be possible. I know it is possible in WPF but the company I am working for doesn't want to make the transition just yet. Basically what I want is to use a background image on a form for the background and I have a docked control on the right and left. I have set the background on both of these docked controls to transparent however it is showing the back color rather than the background image. I tried, rather than setting the background image property, to override the onpaintbackground and onpaint events and use e.graphics.draw(picture, me.clientrectangle) but it still seems to just pick up the backcolor as the true transparent background so I'm wondering if it's possible to get it to show the background image through the control rather than the backcolor of the form?
I have an app that connects to a remote database.The connection to the database is triggered by the form load event of the main start up form which prompts the user for user name and a password.Here is my problem:Sometimes it takes a number of seconds for the database connection to be established after the user has double clicked the desktop icon. this means that during this period it appears that no action is taking place until the startup form becomes visible.Some impatient users assume that nothing is happening and double click the icon again.What I want to do is to have a graphic image or something pop up on the screen immediately when the program starts that displays something like 'Connecting To Database, please be patient"
I have a 18kb 1024 x768 jpeg image that is set as background image of my form. The problem is the form now lags like crazy. How can I eliminate the lag?

I added an image as the background image for a form in VB.net. When I run the program, after approx. 5-6 seconds, the image partially overlays itself, as in an offset overlay of the underlying image. I never had this problem in VB6, but I did have it the other time I used a background image on a form in VB.Net.
Basically I'm trying to make a layout change on a form if a link label is pressed. My main form I want this on has a "default" layout with a background image in place. What I want to do is, name the link label "Plain Layout". When the link label is clicked, remove or "hide" the background image and replace it with the background color of "control". After this action is performed, I need the text to change back to "Default Layout" and "show" the image.
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've been trying to make an image viewer that keeps top most while I do other things (like typing, etc), so I don't have to hop windows, or sacrifice screen real estate.I made a main form, and a configuration form (opened by pressing o), with options to set the main form's opacity (working), the picture displayed (as the form's backgound picture, not working), and if the main form stays top most or not (working).
Instead, the form just keeps displaying the image I set in the IDE.I first used a picture box to display the picture, which did not work, and decided I didnt need to have a picture box if I set the picture as the form's background picture.I tried looking at what could be going wrong, but couldnt find out much more than the path is being delivered to the main form.I'm working on Vista Home Premium 32bit SP2, VS2003, and here's the code.PS The code links to a D:ath-fin.jpg that I used as the default background picture, and the code is for 2 seperate forms.
Public Class Form1 Inherits System.Windows.Forms.Form #Region " Windows Form Designer generated code " Public Sub New()[code].....
I am trying to put an image selected by the user into the form background. This means that an image from a specified file destination to be set as background.
I'm making a tileset creator and everything is working fine so far except previewing a tile. The way it works now is it gets the image from a picturebox and calls the following code when scrolling the mousewheel. It functions fine but there is a border appearing between the tiles and I can't figure out why. The source image is 32x32 in size. Most likely it is the graphics class not measuring in pixels or something.
Public Sub ResizePreview(ByVal dSize As Drawing.Size) Dim bm As New Bitmap(TileImage.Image) Dim pTile As New Bitmap(dSize.Width, dSize.Height,
I am trying to assign a button to let a resource ( JPEG image ) become the background of my form. But instead, the background becomes blank. Here is what I wrote:
Public Class Choose_Background Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Me.BackgroundImage = My_Project.My.Resources.african_lion
Lets say i label "label1" , and 2 buttons named "button1" and "btnRefresh " [code]So , when user press the button 1 , the text will change. But what should i put inside btnRefresh to reload the forms ? and display the default label.text = "Form Load" ???
I am adding records to a database from a modal popup. After hiding the modal popup, the page has not been refreshed (even though I have Re-bound the controls). I have reviewed a few postings on the web about this but the solution still evades me. I have attached my code after removing some of the extra detail.
It seems I need to cause a postback, but I don't know what needs to be changed. Some posts have talked about the extender being misplaced.<asp:Content ID="Content1" ContentPlaceHolderID="Head" Runat="Server">
I use background worker almost daily and works great. Today I came to an instance though where I needed to put my background worker in a separate project then the one I was running because I needed to use this class in two different projects in my solution. When I tested the coding on a winforms form, it works perfectly, handling my coding on the background thread. When I try to reference this class from an external project, all of my coding seems to run just fine, but it does not appear to be doing anything on a background thread as it should be, causing my main window to lockup.
Is there any way around this / what is the best practice for ASYNC calls in an external class.Note I basically created a class that u call start, and an event fires when data is ready, so it's not like my external project is waiting for the method to complete.
Solution ABC has two projects. Project A and Project B. Project A is my WPF application and B is my DLL doing the work. Inside project A I have

Is there a way to somehow "stabilize" the background image on a form, because the way it is now, makes it almost unbearable to use background images. I have a transparent panel that has a scroll bar, and when you use the scroll bar, the background image goes all "weird". It also starts flickering when you resize the form, and all in all, it's not that enjoyable to use.
