I need to have a custom background on a panel that can be resized with the form and want to know how I should go about designing it. Maybe have three images the left side, right side and the middle is just replicated? The thing is I would like for it to have a border and there will be buttons attached to the top edge so simply stretching a static picture may make the buttons not line up properly.
View 1 RepliesI have a FixedSingle Form (I actually wan't to simulate the MessageBox). Only if i disable the ControlBox property the Form can be resized.
I have tried VB6 also (just for comparison), where everything is "OK" (as I expected it to work for me).
I have custom collapsible panel control. I put it into a FlowLayoutPanel. he FlowLayoutPanel is docked within my form. The Panel Anchor property is set to Left/Top. The purpose of the anchor is so that if I want to put multiple panels in the FlowLAyout Panel, they will all stay snuggly together when they are expanding and collapsing. The panels work fine.

I have created a custom Panel Control as follows:
Namespace CustomPanelControl
Public Class CustomPanel
Inherits Panel
Public Sub New()
MyBase.New()
[Code] .....
Now I need to use it and make it fade in and out. This is a panel containing typical play, stop, FF, REW controls over a media player. Just like Windows Player or VLC, I want the panel containing the controls to fade out on mouse leave and fade in on mouse enter.
I have created a basic OS with VB.net and in that I have a panel docked at the bottom which would be my taskbar. My problem is if i minimize any forms or programs I open they all minimize to the windows taskbar. How can i make them minimize to my panel?
View 3 RepliesI've been programming a Fisheye-panel that holds image and make it behave like the icondock in Mac Os X. But now i have a problem. When i add to many item, i want them to shirk, to make room for more, or grow when i remove icons. This is the behavior i get: When i want them to grow, they don't grow at all. When i want them to shrink, they shrink, but leaves lots of empty space (like replacing a photo from a frame with a smaller photo. The image shrink, but not the frame)

I'm trying to create a simple transparent PANEL control. I want to create a custom control based on the existing Panel Control with a property added called "transparent" which can be set to true or false. If it's set to true it's transparent(not invisible). So if I place it over some controls in a form say a button or text box... they are visible but disabled.
View 2 RepliesI have inherited the standard panel control to create a panel having custom border color. The problem is, while the panel is on a form and any other form is moved across it, it paints hapazard lines of the same color as the panel custom border color, all throughout background of the panel. I tried to Refresh or Invalidate the panel in its paint event but of no avail. The same is happening while designing in the design editor too. See attached image. Why is this happening and how to get rid of it? My code follows:

I created a custom control and I'm trying to insert it into a panel, but also center it.The control itself is larger than the panel, so I've set the AutoScroll property of the panel to True. I think that might be affecting it. Perhaps I should just offset the Y axis a bit.But, either way, this is what I'm trying:
VB .NET
'Create the control
Dim AutomationReport As New AutomationReportControl
[code]....
It works just fine with the X axis, but the control is out of bounds vertically. About 1-2 inches of the top is cut off.
I am fooling around with VB for a while now and it is not the first time I created custom controls to use in an application. The situation: I have a database application (FormView / not GridView). The form is designed the following way: At the left I have a Panel1 with TextBoxes and other controls to view / edit dataset records. At the right I have a Panel2 which contains on default a custom control (a number of PictureBoxes mainly) to view / add / delete pictures associated with the currently viewed data record.
On a ButtonClick at a special button on the ToolStrip, I would like to replace that custom control in Panel2 with another custom control (which contains a search with different search possibilities), so, I basically throw out the PictureControl and load a SearchControl instead. This is the first time where I actually designed the custom controls within the actual project. In past, I always developed the custom controls seperately in a new project and later imported the dll. However, my first attempt just does not work and I don't even know where I should start troubleshooting since I don't get any errors.

I created a custom control. I put it on a form with Dock = Top. I place a standard Windows Panel below it and set it's Dock = Fill. I would expect the top of the Panel to bump up against the bottom of the custom control, but instead, it goes underneath it and jumps all the way to the top of the form. This behavior does not seem to exist if I place two Panels on the form and set one to top and the other to fill. The second one bumps up against the bottom of the first one, as I would expect. But my custom control (from UserControl) does not seem to work this way. Do I have to set something special on my control?
View 1 RepliesI'm trying to create a custom control that contains a List(Of Panel). I quickly ran into an error about the base class Panel being nonserializable. So I created my own class that inherits from Panel and implemented the ISerializable interface. At the surface, everything appears to work, at least everything at design time. I don't know what would happen if I tried to run the application. Anyway, the errors occur when I try to open a file that contains my custom control. For example, I create a new Windows Form and add my custom control to it. I save the Form and close it.
Then I try to open the form and get the following error: Object of type 'MyTestApplication.SerializablePanel[]' cannot be converted to type 'MyTestApplication.SerializablePanel[]'.
I don't know what I'm doing wrong? I've opened the XML file to see what it's actually writing, and read the header notes about using binary base64 serialization. I think that's what I'm using, but I'm not sure.
Below is the code for the class SerializablePanel:
Imports System.Runtime.Serialization
Imports System.ComponentModel
<Serializable()> _

I created a simple custom controlled Panel for double buffering. When I use the control in my toolbox it works just fine, but when I attempt to add controls inside the panel those controls aren't staying when I move the panel around. My custom panel isn't acting as the controls' parent. I verified this by looking in the designer code.
I tested a standard panel on the same form and it works perfectly normal - as I drag the parent Panel the interior controls move along with it. It is only my custom Panel which doesn't seem to detect when another control is placed within it.
Here is my constructor
Public Class DBPanel
Inherits System.Windows.Forms.PictureBox
Public Sub New()

I have a project with 150 (i counted) Items in the "MainProject Components" area of the toolbox panel.These 150 classes are mostly database related objects like table adapters, and datasets that i hardly ever use. I also have about 10 custom classes that i use often.When i need to access the toolbox, I have two issues that i would like to resolve.
1.How do i organize the toolbox to separate my custom controls from the table adapters and datasets?
a.I have created a custom tab within the toolbox.
b.I have dragged and dropped my controls into this new area.
c.All is well until I exit my program and re-open it. Voila they're all back in the MainProject Components" tab.
2.How do I force the IDE to instantiate the toolbox panel as completely collapsed?
Im using this code
Private Sub Form1_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.MouseEnter
For i As Integer = 38 To 2 Step -1
Panel1.Height = i
Next

I have 2 panels on the form butttt for panel one i want to slide height and panel 2 i want it to slide width.
I need to center the red panel in the middle of the dark grey panel, when you resize the form the red panel should be in the middle, and the red panel can't be resize, anyone have a code or property to do this?
View 2 RepliesFrom my understanding PictureBox's don't support transparent backgrounds. What I am trying to do is just have a single picture that needs a transparent background just to be on display with my form. So how do I do this?
View 5 RepliesI am using a picture box to load an animated gif as a background on top of my form (same size as the form). On top of that I have a standard label with some text. I have made the label background transparent but it doesn't display correctly with the animated picturebox behind it. The label background is transparent but it doesn't draw the animation correctly under it. It almost looks like it is drawing it at a few frames behind. Now, I know I can draw the text on the animated picturebox by hand (I have done that before) but I am not sure it is possible this time because the labels are part of custom controls.
View 4 RepliesSeen this question asked a lot but can't seem to find an answer. So here it is. Can you use a PNG with an alpha channel as the background image for a VB app? I don't care about changing the shape of the app rectangle is fine. They just want to use a character with a drop shadow behind him as the background for the app.

I'm trying to create a fake virus for a collegue who keeps changing our desktop backgrounds. I have created a form in vb 2008. It as a window security icon and coule text boxs saying virus has been found, it has 3 buttons (Repair), (Quarantine) & (Ignore) and a progress bar on the form.

How can i do this
I just made a basic browser using VB... So now I am wondering how to make it resizable so that when it is resized the browser and buttons remain in same layout but the text box and browser space resize to the new screen size and the buttons do not change layout or get covered (it has buttons for back, forward, refresh, home, and stop then a text box for the url and then a go button, I want them to remain in same order but the text box to enlarge and the go button to keep to the right side of the box - and I want the browser spot to grow too).
