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.

View 5 RepliesI'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.

View 1 RepliesThis 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)

View 3 RepliesI'm writing a tool that will have -at some point- to create a torrent. Now the tool is big and 'creating the torrent' is only a small part of it so I thought I can use a command-line utility that creates torrents but sadly it seems that there are no such tools available for windows ( found some for linux ). What are my options here? Should I just write a tool that creates torrents out of directories (I don't even know how a torrent file should be structured)? Or is there a way to control a GUI-Based application using my VB.NET program? ( Guess only C can do that, right? )

View 1 Repliesi 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]
View 1 Repliesfirst wanna say, awesome forum here wish i'd found it sooner so basically im trying to create a tool for my group (6 people) that tracks tickets they work, basically we work jobs by ticket request and im trying to create a tool/program where they can enter:the ticket number if they completed,pending etc and notes of the job i figured it was gonna be easy, do a simple GUI that saves the info to a excel sheet or a access DB file.
that is basically how it looks. what im trying to figure out and hoping to get some help on is what is the best way to go about this? would a access DB work out better? (since i am hoping to expand it later like add a auto date/time function etc)how do i get it so when i hit the "submit" button it copies the fields and puts them into the DB file?

View 14 RepliesI am wanting to create a logon similar to the Windows Live logon, so in other words. user has frmLogon and is located in Australia. The user enters his/her details and then the program connects to a server in the United States and checks the Username and Password to make sure it is correct if it is correct it allows the user to logon and move to the next stage, if it is wrong it will give him an error message. I am wondering if anyone has a tutorial or source code laying around that I can rip apart and see how it works. I want to put the database on my server and connect to it from my desktop using the logon form.
