Change The Backgroundimage Property Of The Main Form - Me.BackgroundImage = Nothing ERROR In 2008
Dec 3, 2010
I been trying to create a section for my program to change the backgroundimage property of the main form. let me show the code: (some parts may be bad written but I was trying to try to find the problem) this code is a click event from a button
I am using images imported into My.Resources as images for items in my game. Now for the saving procedure I use pnl.BackgroundImage.ToString but that returns System.Drawing.Image. What I'd like to know is how to retrieve the name of the resources object that is the image of the panel.
defauld the usercontrol create(when is used) the backgroundimage property, but these property can be blocked? i'm asking these, because i need the entire control in that property
I'm from Holland (The Netherlands) and new to this forum, I'm not 100% sure if I'm posting this thread in the correct subforum... I don't I have a little experience in Visual Basic .NET 2008 Currently I'm developing a program for my job in which you can follow a checklist for doing a certain procedure. With every step you have to click a checkbox and so on. It's saved in an XLS-file and blahblah, all irrelevant for my question.
I've got to the point that I'm almost pulling my hair here, because everything went fine so far with coding my program, but this simple thing I can't solve What I'm trying to do is, change the BackgroundImage of a Button when you click on it. If it is Image1 at the time of clicking it should change to Image2, and vice versa.
I'll explain this briefly as I need to be sure pretty quickly... basically, I'm developing a game. after the user gets 5 points, an alert box comes up saying "proceed to next level"... on the next (second level) I want the background image to change....
Now the default background is not a picturebox, it's actually part of System.Drawing.Bitmap I am using the same form throughout the entire game, so when it says "Proceed to next level" the game stays on the same form... Here's my Select Case statement to tell it to change the background image:
how to remove a backgroundimage in the code whenever I activate colordialog :
[Code]...
I have a backgroundimage on the Me.(form1), I want it to be replace by the color choosen by the user with colordialog, right now it only changes every other form because the : me.backcolor = colordialog1.color has a backgroundimage.
I got a PictureBox Control with a BackgroundImage. Related to the active Image I will show the next image by manipulating the name-string. But how to get the name of the actual shown image? All my images stored under ressources.Following wont work:PB.BackgroundImage.ToString it will give: "System.Drawing.Bitmap"
I am writing a simulator for a complex technical system. I have created a custom control which inherits from the Button control. My project requires around 100 of these buttons, which function identically except for one difference. The background image cycles between 4 different images, (depending upon whether the button is pressed and/or the state of a Fault parameter), and this group of 4 images is different for many of the buttons. So when I drag a new control onto the form, I'd like to be able to specify which group of 4 images to use for this button.
Currently I'm using this syntax: if not IsFault and isOn then MyBase.BackgroundImage = My.Resources.FaultOnButton01 ...
But this means I have to change each image in the code for each individual button. To simplify matters I though of using the Tag attribute. That way the class code can select the images by a process like this: if not IsFault and isOn then Mybase.BackgroundImage=My.Resources. + mybase.Tag + "01"
Obviously this syntax won't work, so my question is: How can I pass a built-up string value to the MyBase.BackgroundImage?
Can the background image in a picture box be moved, or located some where else, not the top left corner?I am aware of the layout that can be changed but that is not what I am after.
Private Sub PictureBox3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox3.Click If user.Right > PictureBox3.Left Then PictureBox3.BackgroundImage = (My.Resources.dooropen) End If End sub
Will not work as it should, when my player (rectangleshape) right is more than the picturebox.left it will not update the picture of the picturebox.
I have a panel that has a BackgroundImage set to "zoom". Because of this, the image usually has some grey "letterboxing" showing the panel beneath the BackgroundImage. I want to paint on the Graphics Object of the Panel using its paint event handler. Is there a way to contrain my painting to just the image part of the panel? Is there a way to find the rectangle that the BackgroundImage is occupying within the panel?
P.S. I don't want to make a graphics object from the BackgroundImage because I'm already using that for some other "paint layers".
A tabcontrol's backgroundimage caused severe flicker problems when resizing a windows form. By setting that property to NONE at designtime and that adding it at the very end of the processing pipeline & after the window had been maximized, the flicker problem on initial form load was solved.
HOWEVER, now when a tabpage resize event is fired, I would like to remove that image at the beginning of the resize and add it back to the tabpage at the end of the resize event. The following code however does NOT work. I get an error in the resize event, Property cannot be found.
Private Sub Form1_Shown(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Shown TabPage.BackgroundImage = My.Resources.GraphicallyIntenseImageToDraw
I am using VS2010 VB.net and I am having issues with what would normally apear to be straight forward in VB6... I am looking at a control that will alternate its backgroundimage between two images, I wish to check which image is currently loaded to the control and change it to the alternative image.
If A1RectangleShape.BackgroundImage = my.resource.Image1 then A1RectangleShape.BackgroundImage = my.resource.Image2 else[code]....
This only yields the type of image thats assigned to the control "System.Drawing.Bitmap" how to return the backgroundimage file name thats been assigned to the control at runtime, IE Image1 or Image2.
I'm trying to update every millisecond the BackGroundImage of a PictureBox. But it don't works. I think that it comes from the figure that I update every millisecond in the PictureBox.[code]
Is it possible to set an IMAGE or BackgroundImage for a button from an online resource such as a [url].... file in any way at all . I would like to do something like this in a WINDOWS FORMs based application.>>
The panel is 989 x 516. The bitmap is 989 * x, 516 * x. The error comes up when I try to increase x to more than 10. Is there some kind of limitation with the panel's size or the bitmap's size? If so, how can I work around it?
I need some help to understand my options to get this working. I try to update a textbox control by a property-changed event from a class variable. I've digged around for a day and have a vague understanding that this can be solved in three ways:
1. Using some "if InvokeRequired", "Invoke" code in the handler method 2. By programming a special delegate class for this variable 3. By using a databinding directly linking the control (textbox) to the class event
Now.. Are these options correct? And would it be possible to get some help to show these three solutions in actual code (relevant to mine)? I can't seem to manage to sort all the information to a working code. Also, what are the pros and cons of the different solutions?
As my code stands now, it's obviously none of the above, as it gives a cross-thread error, as indicated.
I am wanting to display my Application name in the text property of my main form. This is the code I a using: Me.text = My.Application.Info.Title & " " & My.Application.Info.Version.ToString I am wanting to change the name of my project from when I first created it and for this new name to be displayed via the above code.
I have changed the name under the properties setting, yet it is not updating.
When the user run the application I would like to show the File menu->ServiceMenu form and the main menu should be allways on the background. I try the following: From the main menu load events call the ServiceMenu routin.
Private Sub ServiceMenu() Dim szt As New sztetelek Me.AddOwnedForm(szt)
[code]....
My problem the following the new ServiceMenu (szt form) show in the right position but cannot get focus. My user have to click on it to the form gets the focus however if the user click the File-ServiceMenu this forms works well and get the focus.I think the main menu get back the focus (If i press the ALT the File menu dropdown .... )
I'm working on a simple base form in which all the other forms in the project will inherit. This base form only adds 5 properties (at the moment) dealing with painting a gradient background. The problem I'm facing right now is when I change a property on Form1 (the test form) and click run it doesn't show that change. I also checked the .designer.vb file and when I make a change it's not added to the code behind file, I'm at a loss right now to why.
What I have is a user control that has two RichTextBoxes. In the user control, there is RichTextBox1's TextChanged event, I want it to set RichTextBox2's Text to the same as RichTextBox1's Text, I'm currently using: RichTextBox2.Text = RichTextBox1.Text. The user control is on the main form, when I run the application and type I get this error: StackOverflowExecption was unhandled. [Code]
I would like to be able to change a single property for every form by code instead of doing it manually. I'm a little new to .NET development, and I thought I was on the right track with the System.Reflection class, but I still can't put all the pieces together. Here is a basic outline of what I'm thinking (pseudocode):
I inherits textbox Control and I added some new properties to it .one of these properties value i want it to change it's value in desgin time when i change Name property of the new textbox
Public Class NewTextBox Inherits TextBox Private _txtSubName As String = String.Empty
That is the property for set or get SubstringName of Textbox
Public Property SubName() As String Get Return _txtSubName[code].....
that's the property i want to change it's value when i change Name property of the control.i tried to overrides Name property but it's not overridable also i trieds to overloads it but it doesn't work in desgin time.Here is something i tried but it's wronge.
Private _txtName As String = "" Public Overloads Property Name() As String Get[code]......
