I have a ScreenCapture class that allows me to capture the content of the screen by specifying a X Y value of the top left and X Y value of the bottom right corner of a rectangle. This all works fine, however the problem that I have is that I want to capture the content of a panel on a form, the panel obviously has a location X and Y which gives me the top left position and I can use the width and height propoerty of the panel to determine the bottom right position. The problem that I have is this obviously gives me location of the panel on the form and not the screen. The other problem that I have is that this form is a MidiChild for another form.
So basically what I want to know is how can I get the location of the panel but as a screen position?
I have only recently started using VB.NET after having a little experience in VB6. I am trying hard to force myself into this OOP mindset. I want to know if a certain thing is possible.
I want to be able to call a function in the beginning of my main form's startup sub. The function call would look something like this.
Code:
Private Sub frmMain_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim Username, Password, NewPassword as String

Apologies as this has probably been answered a million different times a million different ways already. I'm trying to control the mouse. I wish to move the mouse to a given pixel position (x, y) and cause a click. I don't want this to be limited within a form, as I want to control another application. I'm using VB 2005.

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.

View 3 RepliesI'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.

View 13 RepliesUsing graphics paths for designing...but am getting an error when trying to add a shape to : _shapelist.add(createshape())
It says : Value of type 'system.drawing.drawing2d.graphicspath' cannot be converted to '1-dimensional array of system.drawing.drawing2d.graphicspath'
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?
View 4 RepliesI'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.
Is this where i would post a picture of my interface and get feedback on changes for easier use? If not is there someplace on this forum or any other forum to do this?
View 1 RepliesSo 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.
Ok I have this: This makes a sub called 'graphicspaint' then writes "demo version" to a picturebox1

I am working on a graphics application. If there were, for example, 3 rectangles in the picturebox. If you were to right click one of them a contextmenu would pop up. In the context menu you are able to click a button called Fill. When you click fill the selected rectangle gets filled in with the colour white. The rectangles are drawn by the user.

View 1 RepliesI'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?
