I created an application in VS2005 that draws text with a custom font and color. The images look great from my XP machine. But from another machine running Windows Vista, the graphics are messed up. It seems that the transparencies inherit the default black background so there's this gray'ish/black haze around the text...
View 1 RepliesI'm making a custom class that mocks the System.Drawing.Rectangle class because the Rectangle class doesn't have a name property. I need a name property because I am adding all of my rectangles to a collection and I need a little more info stored than just their locale and size. So I changed the _onPaint event but nothing is working out when I run the program?

Public BackgroundColor As Color = Color.Blue

I have several picture boxes on a form (frmMain).My question is, how do I paint a point on a particular picture box at the location specified by the coordinates of the current mouse position? The snippet below shows defining some canvases and pens. But I'm not sure how to capture the mouse position when the mouse is over a particular picture box and how to paint the actual point at that location.[code]
View 3 RepliesIGraphics and drawing and invalidating thing.I have improved, that I can tell. I won't explain everything, so here's the essential:Technically, my application will let you draw a rectangle on the form. You click, drag, and boom, a red rectangle is there. This rectangle will disappear when you start drawing another.I got that working.But my problem is performance. You see, obviously I have to update, invalidate and paint my rectangle every time the mouse moves while it is in "drawing mode". I do that every time the mouse's position changes.And that is quite a big deal. Every time the mouse's position changes? That's a lot of invalidations and redraws for a decently-sized rectangle!I thought of skipping some mouse movement, like only update every 5 coordinates moved or something. But that would render my goal quite inaccurate.I already invalidate only the regions necessary, that I can tell.
View 5 RepliesI'm trying to make a custom combobox from scratch that multiple instances will share the listbox that holds the data on. I'm trying to draw the button face manually using GraphicsPaths and pens and brushes, but I'm having a few issues with it:
1. How do you draw that down arrow glyph in a way that doesn't look like a two-year-old sneezed on it? I'm having problems with the shape looking like the traditional one.
2. How do you position the listbox that contains the data in such a way that isn't bound by the containing form's render window?
3. I've tried to make the background look different when it has focus, but the OnPaint seems to think it always has focus and always makes the background the "focused control" background.

I am looking at using the better GDI++ font rendering in a web browser I'm making with VB2008. I want to retain the IE web browser component (the default one) but have all text rendered through GDI++ to give a more Safari-like look to the text.What I want to know is, is this even possible? And if so, how complex are we talking?

View 2 RepliesI'm having a problem with the graphics portion of vb.net. As a school assignment, we are making "turtle graphics" applications. I have mine working perfectly, the problem that we are having (not even the teacher can fix it) is that when the window gets sent the command to be painted (ie minimized and maximized) the drawings in the picturebox I am using are completely erased. I am looking for a way to prevent this from happening. I have been trying to store the image as a bitmap in memory, which does not work. Is there another way to draw to a bitmap/image in memory and then output that to a picturebox?

I'm having some problems with custom controls and anchors today. I made a custom control containing a picture box and a vertical scroll bar. When I adjust the form the custom control outer area (the blank part) will adjust to the size of the form but the picture box and scroll bar do not. I have the picture box anchored to all sides and the vertical scroll bar anchored to the right side. They just will not adjust with the control when it is resized on the form.
View 4 RepliesI'm trying to build a custom ListBox control as inspired by the 'Audi Infotainment System' on high-end Audi vehicles.

Basically, i would like my list to act like a normal ListBox except i would like to show say one or two items above and below normally only visible items.
View 3 RepliesI'm trying to bring up a simple right-click menu on a listbox and I'm having little luck with it. I created a basic ContextMenuStrip named "ContextMenuStrip1" and I'm trying to call it in the ListBox's Mouse Click method:
Code:
Private Sub ListBox1_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListBox1.MouseClick
If (e.Button = Windows.Forms.MouseButtons.Right) Then
ContextMenuStrip1.Show(MousePosition)
End If
End Sub
So here's what it's actually doing. The right mouse button doesn't seem to activate MouseClick at all for this object. It is caught in MouseDown, but when I try to call this from that method, the ListBox Index doesn't change. How can I get a right-click to be called from the MouseClick (Not imperative) and how do I get the ListBox to change the index with a right-click?Also, the menu looks like one of Office's right-click menu that can have an image to the left of the text. When I don't have an image the text is about 50 pxls or so away from the left edge. This looks weird. Can I change that?
