Set Pixel In Some Container?
Feb 2, 2012
VB 6.0 had a Set Pixel function, which is not available in VB.net. using a draw ellipse function with parameters specifying a circle one pixel in diameter.The above is painfully slow.I have been drawing graphics in a Bit Map using a Set Pixel function & then copying the entire graphic from Bit Map to a Picture Box. This results in nothing seeming to happen for several seconds & then the entire graphic is displayed in the Picture Box.
The above does the job, but it would be nice to display the graphic as it is being generated pixel by pixel, which was possible using VB 6.0, Might there be a Windows 7 API which would set a pixel? Might Microsoft be considering a Set Pixel function for Picture Box graphics?

I 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?

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.

How can I find out the pixel colour of a certain point on a web browser. For instance,WebBrowser1.getPixelColor(0,0) would get the rgb colour value of pixel 0, 0.It doesn't have to be rgb it might be hsl or whatever.The web browser is showing a local web page that is hosted on a network. If there is an error then the screen goes all grey. What I want to do is, if this does happen, display an alert message like - "An error has occurred

The problem is that it raises the event even if the picture didn't change.

I have a form (say Form1) opened into a MDI Container form, and I want to open a new form (Form2) as a child of Form1. I open it with Form2.showdialog() but it don't act as a child, I mean, I can move it outside the bouds of the Form1 (and even the MDI)

Say I have some constants that depends one of other, and I decided to keep them together in a container instead of keeping it as individual constants in a class.I thought use a Structure for that scope, but compiler force me to declare a private member for that structure.

This is more of a ASP.NET question, but we are using VB.NET so it might be relevant. We just recently upgraded an ASP.NET 1.1 project to 4.0.Once we started running through the app to regression test it, we found that (consistently) if we made a call like DataBinder.Eval(Container, "PropertyName") from a User Control, ASP.NET complained that it could not find the PropertyName on the page.
PropertyName *does* exist on the User Control, but not on the page.This worked up until we upgraded to 4.0.The fix we found was instead of using "Container", we used "Me" to reference the control that the code was being called on.

In my program, I want the user to be able to move an MDI child window anywhere inside the MDI container but I need it to be kept completely inside the container boundary. For example, the upper left corner should never be at a location less than 0,0 when moved left or up. Currently, if I slide the child window too far left, it extends outside of the MDI container window and the MDI container shows the bottom scroll bar.
Is there a way to prevent the child window from moving outside of the boundaries of the container window? I tried adding code to the .move (see below) so that if the new location was less than 0,0 then it reset it to 0,0 but then the child window controls flicker as the window is moved beyond 0,0 and the logic moves it back to 0,0. It appears that even though the code changes the location to 0,0 and the window shows the child moved to 0,0, when the mouse moves again, the window jump back to its unmoved location.
Private Sub MyForm_Move(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Move
If Location.X < 0 Then

I need a recommendation for a data container. I am loading a sequence of letters (Latin characters) into a text string.I then want to pass the individual characters into a 2-D matrix-like container (i.e. populate left to right based on # column assumption).I then want to search for patterns within this matrix using rules similar to that of a crossword puzzle (Left to Right, Top to Down, Left to Right Diagonal).What is the best container to do the anlysis in?I am assuming the decision to this will be based on the search flexibility of the container.My initial goal is to use crossword puzzle rules as noted above.But I may want to expand this to search backward as well (ie. Right to Left).
