I appreciate the reply. I'm sorry, but I'm really not understanding what you're getting at. Could you provide more details, or perhaps some sample code?
EDIT: To expand on that, one thing I don't understand is what I do with that initial value. Let's suppose I put it in three int variables, int R, G, and B. If I add that to the absolute value of the trackbar, in many cases, the result will be over 255, since I'm using the absolute value of the trackbar instead of the delta. The code will be adjusting this to 255. But this will be resulting in a lot of white results. Which makes me wonder if I'm understanding correctly.
Thank you

Alright 
Let's assume an initial background color of RGB 20/50/150.
1) Determine the color component with the smallest value and subtract it from 255. In this case: (Red) 255-20 = 235
2) Determine the color component with the highest value. In this case: (Blue) 150
3) Set the Maximum of the TrackBar to the sum of those values: 235+150 = 385
4) Set the Value (Position) of the TrackBar to the value from Step 2: 150
5) When the slider gets moved, take its Value and subtract the value from Step 2. Add the result of this to the color components of the initial background color (with Min/Max of 0/255 of course) and set it as current background color.
Example 1:
Let's assume the TrackBar got moved to 0. Then we calculate: 0-150 = -150
R: 20 + -150 = -130 ==> 0
G: 50 + -150 = -100 ==> 0
B: 150+ -150 = 0
Example 2:
Let's assume the TrackBar got moved to 200. Then we calculate: 200-150 = 50
R: 20 + 50 = 70
G: 50 + 50 = 100
B: 150+ 50 = 200
Example 3:
Let's assume the TrackBar got moved to 385. Then we calculate: 385-150 = 235
R: 20 + 235 = 255
G: 50 + 235 = 285 ==> 255
B: 150+ 235 = 385 ==> 255
Looks good?
Edit: If you want to achieve that all three color components reach the min/max value "at the same time" so that no value has to be "clipped" (which will probably produce a better result for image brightness adjustment) you would have to apply some slightly more sophisticated math but I think you'll get the basic idea from the above method.

Okay, thank you very much for the additional info. I have work to deal with tonight, but I'm looking forward to trying this, I'll let you know how it works out. Thanks again!

Unfortunately, this didn't work. It's still losing its hue once I get down to black or up to white. Suggestions?
Thanks

Hi there,
I've made the Tic Tac Toe game.
Now I also added the "Multiplayer" function (LAN - TCP - UDP).
My problem is after I created the Multiplayer menutoolstrip and the dialog for the connection, I have some problems to link it up to the game.
Here is my code:
[code]
namespace TicTacToe
{
public partial class Multiplayer : Form
{
Socket sck;
EndPoint epLocal, epRemote;
public Multiplayer()
{
InitializeComponent();
sck = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
sck.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, true);
textLocalIp.Text = GetLocalIP();
textFriendsIp.Text = GetLocalIP();
}
private void buttonStart_Click(object sender, EventArgs e)
{
try
{
epLocal = new IPEndPoint(IPAddress.Parse(textLocalIp.Text), Convert.ToInt32(textLocalPort.Text));
sck.Bind(epLocal);
epRemote = new IPEndPoint(IPAddress.Parse(textFriendsIp.Text), Convert.ToInt32(textFriendsPort.Text));
sck.Connect(epRemote);
byte[] buffer = new byte[1500];
sck.BeginReceiveFrom(buffer, 0, buffer.Length, SocketFlags.None, ref epRemote, new AsyncCallback(MessageCallBack), buffer);
buttonStart.Text = "Connected";
buttonStart.Enabled = false;
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
}
private string GetLocalIP()
{
IPHostEntry host;
host = Dns.GetHostEntry(Dns.GetHostName());
foreach (IPAddress ip in host.AddressList)
{
if (ip.AddressFamily == AddressFamily.InterNetwork)
{
return ip.ToString();
}
}
return "127.0.0.1";
}
private void MessageCallBack(IAsyncResult aResult)
{
try
{
int size = sck.EndReceiveFrom(aResult, ref epRemote);
if (size > 0)
{
byte[] receivedData = new byte[1464];
receivedData = (byte[])aResult.AsyncState;
}
byte[] buffer = new byte[1500];
sck.BeginReceiveFrom(buffer, 0, buffer.Length, SocketFlags.None, ref epRemote, new AsyncCallback(MessageCallBack), buffer);
}
catch (Exception exp)
{
MessageBox.Show(exp.ToString());
}
}
}
}
[/code]
Stuck at combining the Multiplayer.cs to the Mainform.cs (The main game)..
Any tip or ideas for letting me continue my work will be appreciated.
Thanks.

A single response can only return a single file. If you want to return multiple files, you will need to combine them in a zip file. DotNetZip[^] would probably be a good place to start.

If you want two separate downloads you'll need to make two requests. One technique for doing this is to show the user a page that has two hidden iframes and the src of the iframe is the url of your page that pushes the file to the user.

Some of programming SDK have some methods what are in draft status or with some bugs. For example 50% of requests hangs up.
How to create some kind of "time exeption" if internet request hangs up or sometimes hangs up.And redo it until success.
About about = service.About.Get().Execute();
ps Analog Delphi IdAntiFreeze. try{} doesn't help.

You could either set a timer to see if server responds in a particular time, or use a try { } catch { } block to manage anything that happens unexpectedly.

Hello there. I am trying to implement tree node mouse double click event along with context menu strip. Problem is: I have to click three times, in order to get the functionality of node double click. Skeleton of the program is as follows
private void tree_NodeMouseDoubleClick(object sender, TreeNodeMouseClickEventArgs e)
{
}
private void tree_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == System.Windows.Forms.MouseButtons.Left)
{
}
}
What should be done here.... so that I don't have to click three times for the NodeMouseDoubleClick event. Thanks for any input.

Double-clicking on a node means "expand" or "collapse". It then calls those events[^].
You'd have to work against the system to prevent that default-working, as explained on SO here[^].

Hi,
I am developing an outlook ad-in application.
I am able to build the solution but not able to generate .VSTO and .manifest file.
So i am not able to register the addin.
I am using following development environemnt
VS2010 sp1
outlook 32 bit
windows 2008 server 64 bit OS
Can you please let me know where I need to change or some settings need to be changed?
Thanks,
SMA

What does "cannot build the solution" mean? Does it show a compiler error? What article did you use to build your prototype?

My .Net application has registered with a particular table using SQLDependency for change events . Once the table content is changed, .Net application should be notified.
This happens correctly except on Hyper V machines.
Also, for this issue to happen, "Use sharing Wizard" option should be checked in "View" tab of "Organize\Folder Options" in Windows Explorer
Further Diagnostics:
I checked the broker Service and is enabled.
Also, the sys.transmission_queue table which contains any error message in case messages are not delivered is empty.
Any suggestion in this regard would be appreciated.
Thanks in advance.

Hello,
I'm running an exe application in my C# form app. I need to get the data from the exe application and save it on a database in my c# app. How is it possible? Please help.
|
|
|
|

That isn't a question we can answer: it depends on the application that you are running as the EXE file.
Since we have no idea what that is, or what data it deals with, how it stores it, or anything else about it we can't even begin to help you.
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

It's a university project. The exe application is a calender planner. Whenever a new task is added to a specified date, it is updated in the database where sorting is done. If ever the date and time is already booked, a warning message is given.
|
|
|
|
|
That doesn't really help.
It's like calling the garage and asking then to fix your car, and telling them nothing except "it's a Ford".
Think about it: what do you know about the app, in detail. Remember, we can't see you your screen, or access your HDD... or read your mind!

Someone just pointed out about the security risks. I thought it would be wise to use the exe app. I'll just try to write my own calender planner and get data directly then. Thank you
|
|
|
|
|
Well, you're not really going to get the data out of the running application itself. It'd be far easier to get it from whatever storage the application is saving it's data to.

What university?
Saving that data should be done from the original application, not an external one. Doing it from an external app would also introduce security-risks. So, simply change the source-code of the original application.
