Changing Background Image During Runtime?
Dec 9, 2010
i have a program i've made a while, and one of the users wants to be able to load his own images to the background instead of the plain grey that is there now. i've searched and searched, and basically can get this working
BackgroundImage = Image.FromFile("C:UsersMeFileName.png")
i just slapped that onto a button just to get it to work as i was experimenting. but that only works for a file of that name, on my computer, in that folder. what i'm looking to do is get it so a user can browse his own directories for images and upload them as the background on the form. and be able to save the settings as well. but so far i have only seen different ways to load preset images that you can load. if it's even possible? i'd assume that you'd use the openfiledialog command, but i'm not that well versed in vb as of yet.

Although my code compiles, it does not result in a change of the background picture of button1 here is my current code. Is it possible that my condition contains some error? or is the command itself wrong? [code]

What I have done is named a bunch of picture boxes "Q," "W," "E," etc. (the whole alphabet) and named picture that correspond to these picture boxes ("Q.png," "W.png," and so on) and added them to my resources.
For example, the following code would give the picture box named "Q" it's corresponding image "Q.png":
vb
Q.BackgroundImage = My.Resources.Q
Of course, it's kind of a pain in the backside to copy and paste this code and change all the Q's to W's and so on, so I was hoping to create a function to do the job for me:
vb
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
'So that I can run the letter as a string through the function,
[Code].....
Hopefully I've provided enough detail so that it is obvious what I'm trying to do.
Obviously, the code I tried above (the second block) doesn't work - it gives a syntax error. I need to change/write to make this function functional.

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?

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

I made a code that will change the background button when the mouse cursor over it, the user press and release it ,and it work great.The code below is a part of the code I made, which will change the background of the button when click by user.
Method to use:
butclick(sender)
Sub butclick(ByVal butname)
'code reset of button background start
Main.bestassi_bluebut_about.BackgroundImage = My.Resources.buttonbg
[code]....
But I had to reset all of the background of the button first, the picture below explain why I need to do like this:
BEFORE ALL BUTTON CLICKED BY USER:
IF NOT RESET AND ALL BUTTON CLICKED BY USER:
IF WITH RESET:
So is there any better code for this? Because my method seen a bit silly. Is there any code that can change the background of all the button in one time?

Im writing a app using vb.net, which has multiple front ends e.g a windows service and a windows forms app. Ive got all my business logic and database stuff compiled into 1 project (producing a dll) then the different front ends as different projects calling the dll.
In the backend / dll project Im connecting to 2 databases using app.config to store the connection strings and DataSets / TableAdapters. This all works fine .... Until
When I deploy the windows app, it deploys the exe and the dll produced by the backend project. when its installed on a client PC, Im need to point the app at a different db server and therefore need to change the connectionstring, but its packaged up in the dll.
is there any way I can use a settings file within my windows app (therefore deployed with my windows app) where I can define the connectionstring, which onload gets passsed through into my dll, so the backend connects the correct database. I know how to pass standard settings through (strings etc) but the my.settings.connectionstrings seem to be readonly.

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.

I've been following you for some time, and many of the things you've done have helped me a lot, but this time I got stuck and need the help of an expert.I'll explain my case:I'm developing an assistance programme for an online game, and being this the 10th version I release, I wanted to do something special for the users, so I decided to make the programme based on tabs and give it the aspect of a new skin of the game that will be released soon.
As you may have guessed from the Title, I want to change the gray that is arround the flat buttons and on all the border of the tabcontrol, which is docked to the form. Here is a picture of the programme.To colour the tab buttons I used the following
Private Sub TabControl1_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles TabControl.DrawItem
[Code]...
The problem is that I don't understand how to apply the "A Completely OwnerDraw TabControl" to my project, my knowledge isn't so far yet. Is there any way I can achieve the same results using something simplier? Or if not, could someone explain to me how to apply it without making any mistakes?

I have a forms application and I have multiple localizations for it. I've figured out how to add a button to a form, to change the localization and then read all the labels/etc and change them to the other language.What I would want to do instead now is click a button and it changes to the other language the current form but also the entire application so that any other windows opened while the application is open open in that other language.[code]This is the code I use when a button is clicked on a form to change it to Hindi the current form. However I want to when the button is clicked, change application to continue to run on that localization instead for the remainder of the time it is open.[code]
