you're still not cleaning up your resources.

I got resolution problems on computers that run my Windows C# Form application. For e.g. a Label are stretched in under its matching TextBox. The problem occurs on laptops with widescreen. What can be wrong?

You need to check the anchor property on your controls. If they are right, they will fit to any size screen.

Yes I use Anchor. It works perfect on most computers...

Have you checked out the dpi settings in the display properties? These are sometimes set to a non-default value on wide screens.
Standards are great! Everybody should have one!

I concur.
Check your screen resolution (calculate the number of pixels in the diagonal),
and measure the diagonal (in inches). Divide resolution/diagsize and then adjust
the DPI setting (which is a percentage of 96 dpi !!) with Display Properties/Settings/
Advanced.
Example:
Dell Inspiron 17" with 1920*1200 pixels
diagonal = SQRT(1920*1920 + 1200*1200) = 2264 pixels
diagonal = 16.6 inch (measured!)
hence 2264 / 16.6 * 100/96 = 142%
When you set this value, everything on the desktop will probably shrink;
your labels with fit their intended position and size; your desktop labels might
be too small for easy reading (you may want to enlarge it through Display Properties/
Appearance/Font Size).
On the other hand most objects now get their intended size (in inches, not in pixels)
which is fine; some things will become too small, typically some web pages that
for some reason dont follow the preferred text size ("Normal", "Larger", whatever),
but instead use a fixes font size (say 8 pt).
To cope with that, I developed a simple tray tool to temporarily switch screen resolution to a 30% lower value.
Hope this helps.

It's possible to import Office UI into C# using the Microsoft Office Toolkit, or something. That would be the way to do this.

hi,
I've got this part of code
<br />
public delegate void DellagacjaVoid();<br />
<br />
public void pingowanie()<br />
{<br />
if (this.InvokeRequired)<br />
{<br />
DellagacjaVoid delegacja = new DellagacjaVoid(pingowanie);<br />
this.Invoke(delegacja);<br />
}<br />
<br />
string sciezka = "plik.txt";<br />
if (File.Exists(sciezka))<br />
{ <br />
FileStream fs = new FileStream(sciezka, FileMode.Open, FileAccess.Read);<br />
StreamReader reader = new StreamReader(fs);<br />
string linia = reader.ReadLine();<br />
linia = null;<br />
while ((linia=reader.ReadLine()) != null)<br />
{<br />
try<br />
{ <br />
richTextBox1.Text += linia + "\n";<br />
}<br />
catch (Exception ex)<br />
{<br />
MessageBox.Show(ex.Message);<br />
}<br />
}<br />
reader.Close();<br />
}<br />
}<br />
<br />
private void button1_Click(object sender, EventArgs e)<br />
{<br />
Thread watek = new Thread(pingowanie);<br />
watek.Start(); <br />
}<br />
the thing is that the content i read to the richtextbox alright, as many lines as there are in the txt file but also I get as many exeptions as number of lines with the text like this:
http://img444.imageshack.us/img444/6911/88524168zy6.png[^]
can someone help?

You cannot set the Text property of your rich textbox from another thread as the one it was created on. You should first create the content string (you're better of using the StringBuilder class by the way, it's faster) and then assign it to the rich text box's Text property from the thread it was created on.
Standards are great! Everybody should have one!

hi,
to access the object's properties created in one thread from another, you have to define a delegate for that function and invoke that method from the new thread. then only you will be able to change the properties.
example below:
private delegate void UpdateUIDelegate(string text);<br />
private void UpdateUI(string text)<br />
{<br />
if(InvokeRequired)<br />
{<br />
this.Invoke(new UpdateUIDelegate(UpdateUI),new object[] {text});<br />
return;<br />
}<br />
this.textbox1.Text= text;<br />
}
you can now call the "UpdateUI" function from the new thread
this is one of the methods of making your code thread safe.
hope this helps
regards
