i am a beginner in vb 2005 so im tryin to calculate the minimum speed of a car the user will enter the distance in feet, and when they click calculate the interface should give the minimum speed. the formula to find out the speed is : s = (24d)^ 1/2 where s is speed and d is distance. [code]

I'm making my first 2D game, and I've created an object inherited from a picturebox, to use as a little man. I've tried to make it move using a timer, but I'm not satisfied with the result. Sometimes the speed seems to change for no reason.
View 5 RepliesI made a graphics program in VB6... I then wanted to remake it in VB.NET (I believed it would be faster).
To convert it I wrote both the VB6 and VB.NET versions from scratch side by side. What I have found it that the VB6 code is MUCH faster than the VB.NET program... which I can't understand... (Please note that when not rerendering it in VB.NET it is much faster than VB6)
Here is the VB6 code

How do you do this in VB.NET?
EDIT: Also... why do I have to multiply Me.ClientSize.Width by 3 for it to be the right size... it doesn't seem to add up.
EDIT2: The smaller the radsize the more efficient VB.NET is compared to VB6... so perhaps it has something to do with the setpixel in VB.NET

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.

The code is:

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 4 RepliesI 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 Repliesi have a program that calculate a download and up load speed for internet , and i'm doing this by the following for download
1. but the whole code in a timer with interval 1 second
2. calculate the total byte recieved and store it in a variable (s)
3. calculate the new value of total byte received and store it in (s1)
4. s2=s1-s
5. s2 represent the difference in an interval within 1 second is that a download speed ?
i test it with downloading some files from internet using mozilla firefox the values is so close to each other but is that the right way to measure the speed ???
I want two labels that will give an accurate measurement of the current download upload speed. I would like it to be in "kbps".

View 3 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
