I am making a 2D sports game using XNA graphics. I would like to create a drop down menu from which the user can select various tactics. The menu will be a panel so that I can add in various sliders and check boxes, and it will drop down when the user clicks or hovers over a button.

I want to draw a text with 32 bit transparency on a graphics object. When I try, I only get black color in the result.
If I try to draw a line with the same semitransparent color, it works perfectly.
I have this code:
lBitmap As New Bitmap(32, 32, PixelFormat.Format32bppArgb)
lGraphic As Graphics = Graphics.FromImage(lBitmap)
lGraphic.SmoothingMode = SmoothingMode.HighQuality

I was thinking it may be that SolidBrush does not support transparency, but I found a predefined brush named Transparent (Brushes.Transparent) that was a SolidBrush when I looked at it in debug. I tried to use Brushes.Transparent as the brush when drawing the text, and it was successfully not showing at all. That means I get full transparency to work, but not partial transparency.
I'm trying to draw a semi-transparent layer over my entire form when certain events occur, with a prompt in front of this semi-transparent layer (similar to the effect in Windows Vista/7 with UAC enabled)At first I was trying to use a custom semi-transparent panel, but this didn't seem to work at all. As such I'm now trying to use a child form within the form using the opacity property on the form. However, when this semi-transparent form is added to the controls of the main form and displayed, it loses it's transparency.I've got a hacky work around at the moment where the semi-transparent layer isn't actually a component within the main form, and the transparency works then, but obviously this isn't ideal and could potentially cause various issues further down the line.

View 1 RepliesI am trying to create two semi transparent panel.When I click on panel 1, the color is semi-transparent red. Panel 2 will become semi-transparent green. When I click on panel 2, the color is semi-transparent red. Panel 1 will become semi-transparent green.
Using class below:
Public Class TransparentPanel
Inherits Panel
Private mIsActive As Boolean = False
Public WriteOnly Property IsActive() As Boolean

When I click on panel 1, it is semi-red, when I click on panel 2, panel 1 become semi-green. When I click back on panel 1, it seems to draw the semi-red on top and make it not semi-red but more red. The more click I do, the transparent is gone. Is there a way to drop the graphics and repaint it with semi-red? OR, is there a way to restore the graphics to its original state in semi-red? OR, is there a way to clear the graphics and repaint it with semi-red?
I am working currently on a watermark maker and I would like to know how to make a label see through. For example a form can have opacity out of a houndred, so I'm asking how can I do something simular to this in visual basic.

View 4 RepliesI have a semi-transparent custom control in vb2005 - works fine, except I can't get it to update/refresh correctly. If I update the custom parameter _backgroundColor, the control appears to be overpainted - e.g. each attempt to update the colour of the control overpaints the existing colour - until it becomes a solid block of colour. However, forcing a refresh of the form makes the control display the correct colour. Any ideas? I don't want to have to repaint the form just to get this control to render correctly. Code for the custom control is below.

I am making an application in VB.NET that allows a user to highlight some text in images of documents so that the highlights could be saved for future reference, but the original images would not be modified. I figured I can achieve it by creating a graphics out of an image file and allowing the user to draw on that graphics. The problem is - the graphics can not be created from indexed image files, which many of mine are. I am wondering: is it possible to create a transparent graphics surface above an image in a PictureBox control, so that the user could draw on that surface, but it would appear as if he is drawing directly on an image?

View 6 RepliesI am attempting to write a simple 11ball style game. It requires images of poolballs overlapping each other. Since the balls will need some internal intelligence I was hoping to create them as usercontrols.I am having trouble gettiing the control's background to be transparent.Setting the background color to (Web) transparent only makes the background clone the form background color.
View 1 RepliesI am trying to use (and this may be my problem already) e.Graphics.CopyFromScreen() in the OnPaint() method of my control to prepare a background onto which I can draw the content of the control. The goal is a tool-tip with rounded corners and other specific features to replace the default Windows tool tip.
Ideally the tool tip could be antialiased and blended into the backdrop, however at a pinch I could tolerate an aliased boundary. This may also be necessary as the control will often be covering a control with an OpenGL overlay and the whole blending procedure may end up a nightmare.
I have created a custom user control, a persistent instance of which belonds to my applications's main form, overriding the OnPaint and OnPaintBackground methods. The application of transparency however is challenging. As I understand, the graphics object passed to the paint method starts with a copy of the current VisibleClipBounds, where generally the first move is to clear the control with a solid colour and start drawing the main features. My first thought was to bypass the fill and start drawing on the captured background. For the first redraw this works fine, but subsequent redraws keep the previous content instead of re-capturing the backdrop. I hoped that CopyFromScreen would specifically eliminate the currently drawing control from its capture so as to start from a clean base but this is not the case, it captures the rectangle of the new location including the image of the previous location if it is in the bounds.
I've read many articles on how to create transparent labels but it seems to me that my particular case is not covered. Very simply I have a label placed in the upper right part of the form, which in fact is part of the menu strip. The label displays some info to the user but I wish it were transparent. I've tried various methods including
lblAct.Parent = mnuMain '(or Me)
lblAct.BackColor = Color.Transparent
lblAct.BringToFront()
But cant get it to work. How I can make that label in that position transparent?

I copied across all the code and got it going, but when I copied across the tool strip menu it came up with a Red X, where on the old project it was displaying fine. I removed the copied tool strip and dragged a new one onto the form, but even a brand new one with no modification comes up with a Red X. I tried a couple of the suggestions I could find on the internet, but none of them seemed to make any difference.
I tired stepping through the code (F8) but it does go anywhere near any tool strip code. I added a New Sub complete with InitializeComponents, but when it gets to initialise it goes yellow and then next step goes to End Sub. I though in previous projects it went to another class and setup the components on the form. Just got home and thought I would throw a button on the form to see if it would display that and it does.
I have an AppBar application that I've added a few drop down menu items and context menus to, but each and every time I try to access the menus, they appear outside of the form. This is what's happening with the drop down menu button I've added to my status strip, and context menus show up on the right side as well.
View 2 Repliescurrent version is 2008 I'm trying to build an application with a simple MENU. When the user clicks on a Menu Item i want the container to show some controls, now when the user clicks another Menu Item, the container needs to change and show other controls, and so on with every menu Item the user clicks, one at a time.
I thought of panels showing and hiding for every menu Item clicking, but that would use a lot of memory as ALL the controls would be created, some of them just not showing. I also though of an MDI application, but i dont want multiple forms (with the menu bar) opening inside one form. I just want the actual container of one form to change.
We are in the final stages of releasing a new in-house written system within our company. We have opted to create a single system/project containing multiple programs (like a mini ERP system).We are stuck on the navigation mechanism which will allow the user to load the appropriate forms. I am personally not a fan of the Tree View control because I think it is unfriendly to users. I have been looking on the web for some inspiration and I am interested in the design of the OPEN BRAVO ERP system. Before we dive in though, I wanted to get other programmers opinions. What do you find works best in VB 2008?
