VS 2010 MDI Parent With Transparent Objects?
Aug 8, 2011
I'm doing a new interface for my app and I'm using MDI forms. On the parent form I want some objects like Labels and ToolStrips with Transparent BackColor but even when I change the MDI Client BackColor to Color.Whatever or the BackgroundImage and apply a Transparent Object it just doesn't get the color behind it but gets DarkGray instead .
I changed the MDIClient.BackColor with: Me.Controls.OfType(Of MdiClient).First().BackColor = Color.Red

long story short, I have created a ListView type control, using UserControls for the parent control and the ListViewItems. Most the of the control is written and works fine, right up to the point where I tried to replicate the 'Control.SelectedItems(0).Index' property and the 'SelectedIndexChanged' event.
Each child object knows its index value, and could pass this value via the SelectedIndexChanged event (assuming this is how it works in a normal ListView control -- user clicks on an item, and that item fires an event updating the selected index value in the parent object).
How does the child object raise an event in the parent object? I have a feeling this could be done with Delegates, but I'm still learning about their usage.

I have some labels in my MDI parent form that I tired to make the background transparent but if I move the label on top of a form in run time, then the background is gray like that background of the MDI parent.

I usually can find anything I need on google, but this isn't the case this time. I have a com object that is a display control, it displays images from another software that are retrieved from a camera. I am trying to overlay graphics on this image for reference to an operator. I have found how make a picture box image transparent but not over another object. The images are PNG and are set to transparent.

I have a form that displays data. What I would like to have is a button that when pressed will display some test extran textboxes in a dimmed/transparent type of fashion. I can get that using another form, but would like to do it without the second form.

I am developing a new class which is a control that inherits from the "Panel" class. In this new class, I have three objects that are generated every time I create a new instance of the class. For simplicity, I will call this class "garage" and the three objects "BMW," "Lexus," and "Acura." So each new garage has three types of cars.
how can I share a variable from the Parent class with all of it's child objects? i.e. The garage has an array variable called "tires" which all three cars use. Rather than create each car object with the tires parameter, I would just like to keep the tires parameter in the parent class so that all my child objects can use it. I know that normally the parent class should provide the child class with all information when creating the child but it would seem redundant to pass the entire tires array each time since all three cars use the same tires and the tires object never change.

Basically, I am trying to write a LINQ to Objects statement where the relationship is a grandparent, parent, child relationship. (You could also call it a Master Detail relationship.)
In Legacy code here is a simplified version what I am trying to accomplish.
Dim coverages As New List(Of Coverage)
Dim coverage As Coverage
For Each rl In oClaimsPolicy.RiskLocations
coverage = New Coverage
coverage.Level = "Location"
[Code] .....
If is it not clear one Location can have many Items and one Item can have many Coverages. I basically want to list the items and show the relationship between grandparent (Location), parent (Item) and child (Coverage).

I would like to create list of child objects from list of parent object. Like If i have list of bookingroom which has one member room then i would like to create list of room from it.
eg. code:
Dim BookingRoomList As List(Of BookingRoom) = New List(Of BookingRoom)
Dim RoomList As List(Of Room) = New List(Of Room)
BookingRoomList = BookingRooms.FillGrid()
[Code]....
Is there any short cut method instead of iterating over for earch?

I know that this question has already been asked million of times, but until now I haven't found a WORKING way to make this to work.I've a Media Player control, and in front of it (for a logo thing), I have a PictureBox, that I want to make transparent. I've tried million of things, but couldn't get it to work.

I'm having problems with flickering well using transparent TableLayoutPanels. I have a label that I'm using as a count down, it's anchored to all 4 sides inside a TLP and when the numbers inside the label box change it causes a white flicker inside the TLP.I'm also getting a lot of flickering when the programs first opens.url...

When the dialog pops up, the screen dims down almost as if they overlapped the screen with a transparent black layer of some sort. This is easily accomplish able by creating a black form and having its opacity set to half and starting it maximized-which I'm already doing. The problem with this though is I need to do this within a form, so using a panel or anything is out of the questions since transparency really grabs the background image and not the actual controls underneath. Plus I feel if adding a form to another forms controls depletes it's ability to use it's opacity property.The form I need this in is my cash register. It is full screen but if my menu auto hides it still resizes. It has two parts, the order(panel to the left) and the payments(panel to the right). As you could imagine I want the payments portion blacked out until the order is capable of accepting payments(the payment due is greater than 0). Or I'm thinking it fallows the mouse, you mouse over the payments and the orders panel blacks out, and vice verse.
Plus I have tried googling this but no one seems to have the answer on other forums.. Everyone gets confused and the thread ends short with no solution. Apparently though experts-exchange has the answer, but wants me to pay... so no. Wish their site would stop showing up in my google results.But did have an idea of what I could do. My best guess was I could take a snap shot of just the panel I want to black out. Set it as the background image for that panel THEN use my overlay panel(back color sent to black) overlapping the appropriate section with it's transparency set to half.. But still I'm not sure how to take a snap shot of just a particular.control..

Okay, I'm making a fresh start and re-exploring my options. I'm trying to put a layer of transparency over a program that will act as a drawing layer. The cursor should be able to sniff to see whether it's sitting on transparency, or a drawn object. Transparency it will click through, while clicking on a drawn object will enable the user to edit said drawn object.
I've been trying to do this using a user control I made from scratch, but this is starting to look more and more like a dead end the deeper I get into it. Currently the layer of transparency works, along with the cursor sniffing, but the user control refuses to be brought to the front.
Any ideas on other ways to go about this / ways to make the user control work?

I'm playing with some new UI for one of my projects. I have created a digital display board in Photoshop and added a Picturebox in my VB project and used that image in it.But what I want to do is, I'll be displaying some text above that image. When I tried placing a LabelBox and setting it's BackColor to Transparent, doesn't work !
The text in the LabelBox will be changing each second. So, what I'm doing is using a Timer control with 1000 as interval and displaying the text.What will be the solution ? Do I have to draw the text on the picturebox on Paint event ?

I have code for make the usercontrol transparent:
Protected Overrides ReadOnly Property CreateParams() As CreateParams
Get
Dim cp As CreateParams = MyBase.CreateParams
cp.ExStyle = cp.ExStyle Or &H20
'WS_EX_TRANSPARENT
[Code] ......
These code shows the usercontrol transparent. But when the control moves I see that these control needs time to be transparent or drawing an image. Why so many time(maybe 2 seconds)? And why I can't use directions keys on keydown event? (The arrow keys are ignored).

I have a little "designing" problem in VB 2010. So, I made a cool abstract background for my application in Photoshop. And I wanted to make the form transparent and BorderLess. But, in order to imitate Windows, I also had to put in a very small black outer glow. So, I made the BackColor in a DarkGreen, then the same for the TranksparencyKey. BUT, because of the outer glow, now it looks like this:

I have a form, and the background color of the form is set to the transparency key, making the background of the form transparent. The problem I'm having, is that the form cannot recognize the MouseClick event (when I click on the transparent background of the form). I figured out that the transparent background is triggering this problem. When I shut off the transparency, everything works fine.My question is.. Is there any work around? I still need to use the form to be able to access certain objects that are rendering there, so I don't think I could use something like a "Panel" for example, because the objects will render underneath and possibly make them inaccessible.

I know you can make certain parts of a form transparent by setting the transparencyKey of the form to the color of your choice.
vb.net
Me.MdiParent.TransparencyKey = Color.Fuchsia
Me.BackColor = Color.Fuchsia
Once I set the form to be a MDI Container, it seems to just ignore that function.
On my MDI Container form I have a menu and that is the only thing I want displayed. I want the container itself to be transparent. The forms that get loaded into the mdicontainer will be shown normal.

I'm having problems making an image properly "transparent"
Dim x As Integer
Dim y As Integer
Private Sub PictureBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox1.Click
[Code] .....
The initial image is Transparent, however, once you create another image very close to it, there is a "box" around it. That "box" is what I am trying to get rid of. I have no clue on how to get rid of it. Yes, I have made the image itself, transparent, as the initial image is transparent. Just any image that makes contact with the other images show the "box".

I'm trying to bring a transparent user control (being used as a drawing layer) to the front, over a page that will be playing video.Me.BringToFront() didn't seem to work, and when I tried Me.SetTopLevel(true) in the load, this gave me an InvalidOperationException. Here's what I have so far, sorry for the commented lines.. lots of trial and error (I'm very new, just an intern at the moment)[code]

I know how to create the Rounded Rectangle, but what i don't know how to do, is make the area outside of the rounded rectangle (the corners) become transparent This is going to be used on a usercontrol, so i really need it to be transparent and not just blend in (ie adapt to the colour of the parent form).
