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.
View 4 RepliesI would like to load a GIF file, and start with the first pixel and check to see if that pixel color is closer to Black, Red, Green or Yellow, then take what ever color it closest matched to and output that color as a number, 0, 1, 2 or 3. So just for a small example a 5x4 GIF would be converted to something like this: 0112223322220111332?

It works perfectly fine. Does anyone know what the problem is?
during the development of my project, i've fall in the need to change the position of some forms, pixel by pixel using a timer.Now, i've checked that the movement is very fluid when form is not very heavy, when it contains few elements, but when it has a lot of elements inside, the movement becames nervous and not fluid, the movement becomes jerky.
View 5 RepliesGiven a rectangle of width w and height h. and a coordinate x,y in that rectangle I would like to identify which triangle I am within.
i.e. the function should take parameters(x,y) and return a,b,c,d or a zero based number representing that triangle index i.e. (0=A,1=B,2=C,3=D) if they are in that order.
I think this would be something like >= the formula of the red line and >= the formula of the green line?
I'd like to implement this in VB.NET
Aside from one small ASP.NET webpage (using VB.NET as the language), I've been programming with Visual Basic 6.0 exclusively for the majority of my programming career (5 yrs or so).
With free versions of Visual Studio out there (Express), I've decided it's time to up my game. I also read this thread recently, which kind of killed me a little inside.
Anyway, I have two needs moving forward. I have to write a couple of small programs that load text files to a database (easy enough), so I'm going to write my next program in VB.NET. The other project is migrating a fairly substantial scheduling program that I wrote over as well. It's about 4 years old and in need of a major update so I figured a rewrite in .NET is the best way to go.
The question is, if I want to make my scheduling program web-based, am I better to use ASP.NET or the Visual Studio.NET. I noticed that it looks like you can create web apps using VS?
i'm trying to make it so that when a timer reaches a certain number, that PictureBox3 has a new location. But I don't know how to make it so that at a certain "time" makes picturebox3 move.[code]
