C# invalid stream Image.FromStream()

I try to make an screenshare application using udp sockets. I first record screenshots on a list than i save bitmaps to memorystream and send with 2 packages. I can merge them on client/server but it doesnt work.
I share my codes it starts to listen at button10 click and start so share at button8click

When getting my emails from my pop3 account the progressBar percentages is getting to 99% why?

What I get is 99% and on the label8 I see 1 and not 0 and the progressBar should get to 100%.
This is the backgroundworker dowork and progresschanged and completed events:
private int numberofallmessages = 0;
private int countMsg = 0;
private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
OpenPop.Pop3.Pop3Client PopClient = new OpenPop.Pop3.Pop3Client();
PopClient.Connect("mail.bezeqint.net", 110, false);
PopClient.Authenticate("mymeila", "mypass",
OpenPop.Pop3.AuthenticationMethod.UsernameAndPassword);
int messageCount = PopClient.GetMessageCount();
numberofallmessages = messageCount;
allMessages = new List<OpenPop.Mime.Message>(messageCount);
for (int i = messageCount; i > 0; i--)
{
if (backgroundWorker1.CancellationPending == true)
{
e.Cancel = true;
return;
}
allMessages.Add(PopClient.GetMessage(i));
int nProgress = (messageCount - i + 1) * 100 / messageCount;
backgroundWorker1.ReportProgress(nProgress, PopClient.GetMessageCount().ToString() + "/" + i);
}
PopClient.Disconnect();
}
private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
pbt.Value = e.ProgressPercentage;
pbt.Text = e.ProgressPercentage.ToString() + "%";
label8.Text = e.UserState.ToString();
label8.Visible = true;
lstMail.Items.Add(allMessages[countMsg].Headers.Subject);
countMsg += 1;
}
private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
if (closingForm)
this.Close();
}
In the constructor I start the backgroundworker and set the progressBar (pbt) to 0%.
backgroundWorker1.RunWorkerAsync();
pbt.Text = "0%";
This is the progressBar code:
In top of form1:
ProgressBarWithText pbt = new ProgressBarWithText();
In constructor:
pbt.Size = new Size(216, 10);
pbt.Location = new Point(8, 312);
groupBox1.Controls.Add(pbt);
The ProgressBarWithText class:
public class ProgressBarWithText : ProgressBar
{
const int WmPaint = 15;
SizeF TextSize;
PointF TextPos;
bool dontpaint = false;
public ProgressBarWithText()
{
this.DoubleBuffered = true;
this.TextChanged += ProgressBarWithText_TextChanged;
this.SizeChanged += ProgressBarWithText_SizeChanged;
}
public override string Text
{
get { return base.Text; }
set { base.Text = value; }
}
void RecalcTextPos()
{
if (this.IsDisposed == true)
return;
if (string.IsNullOrEmpty(base.Text))
return;
using (var graphics = Graphics.FromHwnd(this.Handle))
{
TextSize = graphics.MeasureString(base.Text, this.Font);
TextPos.X = (this.Width / 2) - (TextSize.Width / 2);
TextPos.Y = (this.Height / 2) - (TextSize.Height / 2);
}
}
void ProgressBarWithText_SizeChanged(object sender, EventArgs e)
{
RecalcTextPos();
}
void ProgressBarWithText_TextChanged(object sender, EventArgs e)
{
RecalcTextPos();
}
protected override void WndProc(ref System.Windows.Forms.Message m)
{
base.WndProc(ref m);
if (dontpaint == false)
{
switch (m.Msg)
{
case WmPaint:
using (var graphics = Graphics.FromHwnd(Handle))
graphics.DrawString(base.Text, base.Font, Brushes.Black, TextPos.X, TextPos.Y);
break;
}
}
}
protected override CreateParams CreateParams
{
get
{
CreateParams result = base.CreateParams;
result.ExStyle |= 0x02000000; // WS_EX_COMPOSITED
return result;
}
}
}
The question is if I really downloaded all the emails or there is one left? And how to change/set the code is it will get to 100% and 0 emails downloaded count?
I did a test now I changed the line:
int messageCount = PopClient.GetMessageCount();
To
int messageCount = 5;
And I see in the listView I added to the designer that there are 5 emails.
But what I see in label8 is 7011/1 7011 is the overall emails in the account but for the test I'm downloading only 5. Again it stopped on 1 not 0.
And the progressBar stopped on 80% the text is 80% but I see the green color in the progressBar moved to the end to 100%.
Why it's stopping on 1 and why I see 80%?

How to lower the terrain using OpenSimulator?

I made a simulation in OpenSimulator. I changed the terrain to resemble that of Atlantis and used the OpenSimTide module to have the tide cause the disappearance of Atlantis.
Now the OpenSimTide module works, but for some reason I just can't find out how I make the terrain go lower whenever the tide reaches a specific level. How can I achieve this?

Try
string path1 = Environment.GetFolderPath(Environment.SpecialFolder.MyPictures) + "\\Sample_Pictures";
or
string path1 = Environment.GetFolderPath(Environment.SpecialFolder.CommonPictures) + "\\Sample_Pictures";
Or use
string publicDesktopPath = Environment.GetFolderPath(Environment.SpecialFolder.CommonDesktopDirectory);
var directory = new DirectoryInfo(publicDesktopPath);
string path1 = directory.Parent.FullName + "\\Pictures\\Sample_Pictures";
and fix your conditional
if (!Directory.Exists(path1)) {
to
if (Directory.Exists(path1)) {
so that you don't try operations on an non-existent directory.
To get it to cycle through your pictures, you could use a System.Timers.Timer:
In your Form1 class
private static Timer timer;
Declare the timer in your constructor:
timer = new System.Timers.Timer(5000); // change interval in milliseconds
timer.Elapsed += OnTimedEvent;
timer.Enabled = true;
Create the OnTimedEvent method in your Form1 class:
private static void OnTimedEvent(Object source, ElapsedEventArgs e)
{
// Do what you want every time the timer elapses that interval
nextImage();
}

Label's position is different in xp and 7

I made small application(winforms) to show the cricket score (the world has just started , yay).
It works fine in xp, but in win 7 the label shows a few pixels down in position as compared to its position in xp, which totally ruins everything. ( i hope that was clear )
here is the exe: [REDACTED]
how it looks in xp; http://imgur.com/emcKG.jpg
how it looks in 7(approx): http://imgur.com/sdqry.jpg
also can someone confirm which .net my app requires ? I think its .net 2.0, since the target framework is set to .Net 2.0 .
Thanks
Edit: won't post the exe next time. sorry!

btw how do I get by exe verified , so that normal people can use it without fear ? virustotal.com ?
Edit: oops , I was wrong ,tis not just the label. the picturebox to the left of the label has also been shifted down a few pixels.

It appears, from your screenshots, that the entire box that holds the text shrinks, and there's a blue bar that covers part of the label.
Perhaps it is a resolution issue or dpi issue. also they change color from one OS to the other??
You might need to set the locations and other properties in the code with a static ,hard coded values, rather than letting windows place it from the designer view or using some variable number based on the size of the screen
this is in c#.net should be similar
label1.Left = 10;
label1.Top = 10;

this.Region = new Region(new Rectangle(10, 10, 197, 17));
Delete that. It makes your window too small on a machine with a higher video dots-per-inch setting. Quite common on Win7. A higher DPI makes the fonts taller in pixels. The Form.AutoScaleMode property automatically adjusts for that by making the controls larger to fit that bigger font. Your Region doesn't grow though, cutting off the bottom of the controls. No idea why you use a Region in the first place since its a plain rectangle, I suppose you are looking for FormBorderStyle = None. A form won't allow you to make it too small but you can override that in the OnLoad method. Set the ClientSize large enough to fit the rescaled controls.

This has to do with a difference in the DPI settings on Windows XP and Windows 7.
