Interface And Graphics :: Can Transparency Key Be Disabled

May 16, 2010

During form design and after placing a scrollbar on the form, I ran the debugger and found that the center of the scrollbar was transparent. After playing with this a bit, I managed to stop the transparency by changing the key to bright pink as I have nothing with that color. Can the transparency key be disabled?

Interface And Graphics :: Passing Bitmaps & Graphics To Subroutines As Arguments

Jan 22, 2011

I used to program with Visual Basic 6, so I have alot of old programs that I'm updating, plus I'm learning the new VB2008 methods. I'm writing a program that replaces the old "BitBlit" function which is no longer supported by Visual Basic 2008. It involves three picture boxes, one holds the sprite bitmap, a second holds the mask (silhouette) of the sprite bitmap, and a third has a background image.

I'm working on a design project where I have to use a Graphical User Interface that contains a drag and drop form. It consists of having a window dropped on a wall. Both of them are images to scale. I would like to know what kind of code I would have to use to show the x and y coordinates of one of the points of my window when dragged so when I drop it, I'm dropping in it on the desired coordinate of the wall.

Interface And Graphics :: How To Procede With An Interface Design Approach

May 18, 2012

I was wondering if I could elicit some tips on how to procede with an interface design approach.That is. What is a good way to go about establishing a "work area" where one can have multiple "floating forms" in this area.Can you have a form which occupies the entire windows desk top and the other forms "float" in this space? the "floating" forms would need to interact with each other where pressing buttons etc on them would affect other forms on the "workspace") Or what would be a good way to start accomplishing that? Or is there a better way to get the same effect?

Interface And Graphics :: Link A Class / Object To An Interface?

Apr 21, 2010

I'm trying to make a .dll that contains a lot of basic functionality that a program can use. Currently i am trying to use interfaces to make a lot of this functionallity independend of the program using it but i hit a snag. The Basic idea is that a programmer will create his own object using the interface discribed in my .DLL file. Then implements those functions as he likes. He can then instanciate a controller (found in the same DLL) and sends his custom object implementing the interface to that Controller. The controller can then be started and will take over all the work. I do not know what type of object is send to the controller and idealy i want to program it in such a fashion that i shouldn't care as long as the object send implements that interface.In code I am trying to achieve the following: (quite simplyfied)

.Dll:
Code:
Public Interface MyInterface '<----Decleration of the interfaceFunction GetData() As Integer
Function SetData(Data As Integer)
end interface

[code]....

this propperly. I know that the second i set the interface adaptor in the Controller VS comes nagging that it can not be converted to a "MyInterface" Class. Obviously i am doing something wrong. I can change the datatype that the controller expects to the "MyController" type but that would completely ruin the whole idea of flexibillity. I am hoping someone sees what i am trying to do and can point out where i made the thinking error.

Interface And Graphics :: Draw On Tabpage's Graphics?

Jan 19, 2011

So I decided to make my famous tile selector project, but instead of drawing in a form's graphics, do it inside a tabpage.Well, I managed to get it working, but it seems to... flicker.Normally, setting the form's DoubleBuffered property to True would help a lot there, but apparently, the tabpage has no such property.

When I invalidate the tabpage, I draw two images and fill one rectangle.Following past advice, those two images were created before, just once, and are stored in a variable so I don't create them every time I invalidate the tabpage.

'True' Control Transparency - Control With Motion Graphics (simplicity, A 'video Player' Control)

Dec 29, 2010

Here's my situation: I have a control with motion graphics (for the sake of simplicity, a 'video player' control) in my project. Think of a PictureBox with constantly-changing images. In front of this will sit a second control (such as a second PictureBox of the same dimensions). The topmost PictureBox will be drawn to in its Paint event.

I need to draw very few elements, and the bottom control is updated much more frequently than I need for this drawing. So these elements are drawn to the topmost control. Think of a news broadcast, where they have live video in the background, with a news channel logo, news ticker, and sometimes gradient visible in front.

I'm trying to create that 'foreground' control, and the closest I believe I have gotten so far is the following:

Imports System.Drawing
Imports System.Drawing.Imaging
Imports System.Drawing.Drawing2D

[CODE]...

The 'Opacity' property in the code above is a sort of "scaling factor." The image drawn to the top control may, in different parts of the image, have any alpha value from full transparent to a full 255. This 'Opacity' property is applied to the entire image being drawn, scaling the alpha values of each pixel.

Interface And Graphics :: .NET And Video (re-)encoding?

Apr 11, 2009

I'm considering working on a video encoding framework. Essentially a program to re-encode a video file from one format to another, using codecs which are widely distributed. (Codecs commonly found on the average PC.)Emphasis would be on reformatting - rescaling, cropping - in a visual environment. Is vb.NET a good environment for such an application or would it be wiser to look elsewhere?

Interface And Graphics :: Calling A Draw Sub?

Oct 27, 2011

I've been having some trouble with a draw subroutine in a project I'm working on. The last time I did anything like this in VB, drawing on a form was as simple as calling the Line() function, so I'm not clear on a lot of these things. Here's my code:

Code:
Private Sub drawBox(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles btnDraw.Click
Dim blueBrush As New SolidBrush(Color.Blue)
Dim i, j As Integer

[code]....

The code is just meant to draw a grid of small squares across the form, using the centers() array, which is set up elsewhere. My problem is that I can't figure out how to call this sub. If I use Handles Button.Click or Mouse.Move or something like that, VB returns an error saying that Draw and Mouse functions are incompatible. I can't call it normally, because I don't have values for sender and e.

Interface And Graphics :: Grid In UI And Snapping To It?

Oct 27, 2010

it's been forever since I've been here Now the question, sorry my math brain just doesn't work like it used to.I have a panel that displays an image as the base. That image needs to have a grid over it with 72x72 pixel squares. I have another image that I use as a hover image for the mouse, what I need is for that image to jump to the next square rather than moving smoothly.

Basically it's just a map where you can place building tiles. However you can't place building tiles everywhere so the "place" image needs to move to the next available building spot.
