Nova has developed Social Networking Channel (SNC) for one year. User can add his/her events of their lives to the system; then the system will turn the events into a line presented by Flash. SNC can also interface with other social network websites, like Facebook and MySpace, so users can easily use this system when they visit Facebook and Myspace.
We used Web Client SoftWare Factory as the architecture, and used Nhiberate，AntiXssLibrary，Ajax in the process of developing.
Web Client Software Factory is based on MVP, but it is optimized, so it is more easier to maintenance for good-sized system. We added Nhiberate in MVP, so the logic of the architecture is clearer and the code is simpler. On the other side, Web Client Software Factor is interface oriented; accordingly it is better compare to MVC.
One of the most important feature of Web Client Softeare Factory is Depency Injection (DI). An config file always exists for Depency Injectionto kepp the Depency object. It will return a depency object through a special role of the system. For example:
Public Model User{
String name;
}
Public Controller IUserController{
Public void Add();
}
Public Controller ChineseUser:IUserController();
Public Controller EnglishUser:IUserController();
Public Viewer UserViewer{
Private IUserController _userController;
Public IUserController{
//Get the current DI of UserViewer through the system role form the //config file, the following method can be implemented by the DI //system automatically
Return CurrentController;
}
}

Hi,
My problem is that I want to find a specific color in a certain area of the screen.
I'm using GetPixel[^] to find the color of a specific point on the screen, but it doesn't give me the ability to search an area of the screen.
What I have come up with so far is these while loops, which does the following:
1. Loop through the X values at the first "line" of the area.
2. Set X to 0. Increment Y by 1 (going to the next "line" of the area).
3. Repeat.
In the code below I'm searching in the area between 0,0 and 50,50.
int x = 0;
int y = 0;
int x2 = 50;
int y2 = 50;
while (x <= x2 && y <= y2)
{
while (x <= x2)
{
Color c = Win32.GetPixelColor(x, y);
if (c.R == 128 && c.G == 128 && c.B == 128)
{
}
x++;
}
x = 0;
y++;
}Can this be achieved in a better way?
By the way, as you can see in the comment in the code, I want to break out of the loop there if the specified color has been found, but it didn't work out with the break keyword. Don't tell me I have to use the G word. 
Thanks.

Hi,
as I can see it, the simplest solution is to use a flag, whether the value was found or not:
bool bFound = false;
while ((!bFound) && (x <= x2 && y <= y2))
{
while ((!bFound) && (x <= x2))
{
Color c = Win32.GetPixelColor(x, y);
if (c.R == 128 && c.G == 128 && c.B == 128)
{
bFound = true;
}
if(!bFound)
x++;
}
if(!bFound) {
x = 0;
y++;
}
}
Better way would be to put this while thing into method and call return when you found the Color.
Regards
Sebastian

int x1 = 0;
int y1 = 0;
int x2 = 50;
int y2 = 50;
Color colorCheck = new Color(128, 128, 128);
bool found = false;
for(int x = x1; x <= x2; x++)
{
for(int y = y1; y <= y2; y++)
{
if(Win32.GetPixelColor(x, y) == colorCheck)
{
found = true;
Console.WriteLine("Color found at {0},{1}", x, y);
break;
}
}
if(found)
break;
}
If only MySelf.Visible was more than just a getter...

Probably best of in the database forum...
What database is it (SqlServer/Access etc), do you want to do this in C#, and what do you mean by one common field?

I'm building a screen with windows form. I need to have a start day and end day.
To solve this I'm using two dateTimePickers, one for the start and one for the end day.
When people change the end date before the start date, the start date will be that from the end date.
But when people change the start date to after the end date, the start date should be the end date. So the end date is like the master dtp.
Now there is a problem to implement this in windows XP. The error occurs when people select the start date and press the 'month further' button. When this happens, an event goes of (value changed) and there will be a check (start date before end date), if this is false the start date is set again (event goes of again) and a messagebox is shown.
But the strange thing is that directly after the first messagebox a next messagebox is shown (and the startdate is 1 month higher than before, this loops until eternity (or you close all the messageboxes with pushing enter).
In Windows Vista this won't occur.
I guess that the event (month-further-clicked) is remembered by the computer and therefore occur everytime.
But what is the workaround for this strange bug?

Hi all. I am stuck witha bit of a problem. I am using Threads to do my processing and to update my prgressbar. Below some of the code.
ThreadCode
private void btnRun_Click(object sender, EventArgs e)
{
ThreadStart excelrun = new ThreadStart(RunExcel);
Thread startprogress = new Thread(excelrun);
startprogress.Name = "Update ProgressBar";
startprogress.Start();
}
Code in the RunExcel calling the Progressbar thread.
progressBar1.Invoke(new updatebar(this.UpdateProgress));
UpdateProgress Code
private void UpdateProgress()
{
string filepath;
filepath = txtboxSelectTxtFile.Text;
int lines = File.ReadAllLines(filepath).Length;
progressBar1.Minimum = 0;
progressBar1.Maximum = lines;
progressBar1.Value = progressBar1.Value + 1;
int progrval = 0;
progrval = progressBar1.Value;
progrval = progrval + 1;
lblProgress.Text = ((progrval * 100) / Convert.ToInt32(progressBar1.Maximum)).ToString();
lblProgress.Refresh();
lblPercent2.Refresh();
lblRecordProcessed.Text = progrval.ToString();
lblProgText.Refresh();
lblRecordProcessed.Refresh();
}
As you can see from the above that eachtime the progressbar thread is called it does a read of the whole file to obtain the file size which is pretty inefficient. How can I change this to only read the file size once, store the size and use that to determine the Maximum size?
I am stuck and not sure how to get this changed to work more efficiently.

Set the progressbar's minimum and maximum once and not everytime in UpdateProgess. My suggestion would be to do it in RunExcel where you are processing the file(i guess so). In UpdateProgress keep on updating the current progressbar's value.
Edit - typo

Thanks AbitSmart. I'll try this and see how it goes.

I tried this and I get the following Cross Thread Error when running the App.
"Cross-thread operation not valid: Control 'progressBar1' accessed from a thread other than the thread it was created on."
Any other Ideas??

You will have to use Invoke/BeginInvoke to update the progressbar value in another thread.

Furthermore,

does not make sense. You don't need the actual content to determine file length, have a look at
the FileInfo class.

I have previously tried the FileInfo Class but this then gave me problems in that with the FileInfo I get the file size and then Divide that by 1000 which left me with a rough number of say 237 if the file was 237000kb. The file has more lines than that in it and would abort when it reached 237 lines.
This is why I am trying to do it this way, get the number of records in the file once and pass that to the progressBar1.Maximum. Hope this makes sense?

Yes I saw your earlier post with the 237 problem, which basically was caused by your code acting
as if each line contained 1000 characters.
Anyway, when you need file size in bytes, ask FileInfo, you don't need the content;
when you need file size in lines, loop a ReadLine and count them, you don't need to hold all the
lines at once (just to get array.Length), it is a waste of cycles and bytes, and an unnecessary
limitation to your app.

But my problem with this is that each time the progreassbar thread is called it does a read to count the number of lines. Now, if I have a file with say 50000 lines of data then after each line processed it has to read through the file to get the number of lines. This is just very cumbersome and there has to be a better way of doing it. Like just getting the number of lines once and passing that the progressbar.maximum once?

that's the advise given to you by ABitSmart; rather than repeating his words, why don't you implement it?
