Create A Small Paint Component( Similar To MSpaint But Not The Same Thing) In .net?
Jun 5, 2011
I'm trying to create a small paint component( similar to MSpaint but not the same thing) in vb.net.I have a panel that holds the background image and a picturebox over the panel that I draw on. I'm using graphics to draw shapes and I have my own custom double buffer, meaning that I draw on the picturebox while the mouse ismoving and on mouse up I draw the final image on the buffer image and on paint event the buffer image replaces the picturebox image.also, i have set the form properties to enable double buffering
Me.SetStyle(ControlStyles.ResizeRedraw, True)
Me.SetStyle(ControlStyles.DoubleBuffer, True)
Me.SetStyle(ControlStyles.AllPaintingInWmPaint, True)
Me.UpdateStyles()
my problem is that no matter what i've tried the picture box keeps flickering. as long as the mouse is moving, the paint event keeps getting called and the image flickers like crazy what i need is more ideas(or pseudocode) on how to avoid flickering.

I'm doing the first bit of web-page development I've done in years, in VS2008, using VB.net. I have a fairly simple layout, which is using several nested tables. IE6 displays the layout just fine, but Firefox for some reason shows the whole thing in a small panel at the top of the page, with a scrollbar.

I'm trying to create my own type of spider/search engine thing for fun. I start with a URL, then grab the HTML ...from that I have a REGEX that is supposed to pull out all the links. I figured I would randomly pick one of those and keep going as I save the HTML to my database.[URL]...You can see that I get some real URLS and sometimes I get back some that are not. NOW I return these to a RichTextBox and on the REAL URLs, these get formatted in blue and make a HAND icon when you float over them. This makes me believe that something SOMEWHERE knows that these are good url's. That would be a good thing to tap into so that I could get rid of everything in that box that is not a real URL.

I want my application to be able to communicate 2-way between the application on another computer and the host server which will be running on my computer.I want to use the BackgroundWorker built into vb to create a thing to make it listen for incoming messages, and also send out messages to the client.The client needs to listen and receive, same as the server, because both need to communicate with one another.I do not know how I can make it do either sending nor receiving.I would be using two different background workers to keep the code seperated and organized so that I will understand what code is for what.
I want the code to say that if i receive the message "Apple" without the "" and cap sensitive, then it will change Label1.Text = "That worked, word received Apple" or something similar to that. ( This is because I am ignorant and I want it to interpret the text sent through to figure out what the application is supposed to do, and last time I couldn't figure out how to make it do something when a certain text was received.

I am writing a program that the users can put their signatures on it and I am thinking that maybe I could use MSPaint then save it as an image file and save it on my database. The device I'm going to use is a touchpad. I don't know how to explain this clearly but the idea is simple.User Log IN > Verify User Account > Put their Signature on a picture box. By the way I am using Visual Basic .NET 2005.

I'm trying to create an enumerable class, similar to System.Drawing.Color - My goal is to have places in the code where I can define a variable as the type of my structure, then be presented a list of static values to pick from.I'd also like to use this for a property of a UserControl.I don't know if I'm using the right setup here with the class, structure, etc.I'm just trying to mimic the Drawing.Color class.I'm creating a Public Class called Person.Inside it, I have two Public ReadOnly Properties for Name and Age, their corresponding Members, and a Constructor to create a new Person.Second, I have a Structure called Persons and it has two ReadOnly Properties: Billy and Sally.[code]In my attempt, I get the full freaking .net class library in my intellisense list. Using Drawing.Color, I get a nice pre-defined list of values to pick from.No extra methods.No constructors.Just values.

This is for a WindowsCE project,
Windows WM6 does not allow you to hook in WndProc easily as this has been hidden, I've built a class that inherits from MesageWindow, which allows me to receive Messages as intended.
What I'm trying to do is create an event that will return a value Boolean bypassing base.WndProc(ref m);
basically saying I've handled the event it does not have to, similar to how the Form_closing event would work e.g e.Cancel will cancel he closing off the form.
I've not finished my WndProc function as of yet but you should get the picture.
Code:
public delegate void WndProcEventHander(object sender, WndProcEventArgs e);
public event WndProcEventHander OnWndProc;
protected override void WndProc(ref Message m)

I have an old VB6 application. I want to recreate it in VB.Net using WPF. But I am a bit confused about the "Model View Controller"-pattern. I have two books about design patterns (GoF and J.Bishop) afair this pattern is indeed not mentioned inside one of the two books. I have also searched the internet I found some java-examples. But I have still no clue how I should use MVC-Pattern (should I?) in my new WPF-application.Let's say for example my model (in fact it is more complex) is only a wheel rim (circle) with the properties Manufacturer, Diameter and Depth. The user should be able to modify the properties using textboxes and ComboBoxes.Could somebody create a small example that explaines the MVC-Pattern with WPF?Of course I like reusable classes to have a feasible concept throughout the whole application.

i would like to create a small tool that filters new and old facebook groups, i am almost finished, but one part isnt working the filtering here is the source code, grabbing groups works but checking if they are old or new doesn't, even though it should. There is one more feature not working where it filters the members size it is not grabbing the text it should (instead of grabbing the amount of members its just grabbing something from the beginning of the source code) [code]

I am a beginner on Visual Basic but was able to create the 'skeleton' of the application I need to build. Basically, it is an application dedicated to keeping a check on the vinyl I have. When I buy a new record, I want to effectively 'Add New Record' on Visual Basic and be greeted with a page consisting of various forms such as 'Artist' and Title'. Once these are filled in, I want to click 'Enter' and for all that information to be converted to one of the pages within my application.
Here's an easier look at it...
There are LPs that have 10" and 12" sections.
There are singles that have 7" and 12" sections.
In the 'Add New Record' page I want to also have a drop down list with the above elements in, once 12" LP is selected and all the other forms are filled in and I click 'Enter' - I want the application to send it to the 12" LP section of the application.
