It set the caret, but didn't modify the text display
|
|
|
|
|
Then you use the ScrollToCaret() method.

another way is to use
textBox1.AppendText("some status\r\n");
instead of textBox1.Text += "some status\r\n";

Hi
I know multithrading is explained in several tutorials, but I can't figure out how to terminate another thread gracefully. This is my current code. In thread1 when I dispose s I get an error... I realised this would happen with sychronisation etc. What can I do?
public class Loader<br />
{<br />
PNG.SplashScreen s;<br />
Form1 f;<br />
Thread first;<br />
Thread second;<br />
public Loader()<br />
{<br />
first = new Thread(new ThreadStart(thread1));<br />
second = new Thread(new ThreadStart(thread2));<br />
first.Start();<br />
second.Start();<br />
}<br />
void thread1()<br />
{<br />
f = new Form1();<br />
s.Dispose(); <br />
f.ShowDialog();<br />
}<br />
void thread2()<br />
{<br />
s = new PNG.SplashScreen();<br />
s.ShowDialog();<br />
}<br />
}
cheers

You can't really terminate another thread gracefully. You either kill it ungracefully via someThread.Abort (which injects the ThreadAbortException into the thread being aborted), or you can cancel gracefully by having someThread check for some boolean cancel state over time and exiting when it hits that state.

You error most probably comes from the fact that it is only safe to alter GUI elements from within the thread they where created in. Have a look at the Invoke[^] method.

I will appreciate if some can recommend/advice on which book one can get to learn visual C# a Needed the skill to improve ,right now working windows application
|
|

If you go to the store, many books will suffice for starting out. What I definitly would learn is the ADO.NET part, make sure there is enough explanation on that in your book (more than 1 chapter) or buy another one that specifically handles ADO.NET.

i have been reading a couple books:
-Microsoft Visual C# 2005 Step By Step
-Visual C#® 2005: How to Program, Second Edition
They are both good books in my opinion

There are books for learning to become a MCAD (microsoft certified apps dev), but they are actually good beginners books.
For C# / Sql, try Amit Khalani's MCAD 70-616 Training Guide, its really simple, yet gets a lot of info across

Jesse Liberty's "Programming C#" on O'Reilly Press. Get the updated version for .NET 2.0. Its really written for programmers who want to learn C#, rather than people who want to learn how to program using C#. It was the book my C# professor used, and it is a WONDERFUL reference. In addition, anyting in the Microsoft .NET Development Series helps. I have their books on ADO.NET and data binding in windows forms.
Also, the articles here on codeproject are great too. I've definetely used a couple to learn what I need to overcome some issues I've had.
Good luck.

Can anyone help me with this small problem, The cell position of a ListView is worked out by the mouse_click x,y and the width of the columns. Is there any way to account for the hidden portion of the control when a form is resized and a scroll bar introduced?
i.e.
Example problem with incorrect x,y co-ordinates due to scrollbar offset.[^]
Any help would be appreciated, thanks

Are you using ListViewItem.Bounds ?
|
|
|
|
|
No, the problem is before i need the bounds of the SubItem i need to work out which SubItem it is... using the folowing MouseDown event handler i get the current x,y position of the mouse relevant to the form but it does not account for the 'actual' size of the listview, only the visible portion (or maybe gives me x,y from top-left of the form overall not sure). So somehow i need to get access to the correct size of the ListView irrelevant to the size of the form.
public void EAL_MouseDown(object sender, MouseEventArgs e)
{
li = this.GetItemAt(e.X , e.Y);
X = e.X ;
Y = e.Y ;
}
I found this article: http://www.codeproject.com/cs/miscctrl/CSharpHitTest.asp
and it has some interesting comments on the horizontal scrollbar problem, gonna chase them up.
Thanks

How do I catch for e.g. a <ctrl> + s (User want to save) to my Form (C#).

If you want to add a shortcut key combination to an event handler you could look at the:
System.Windows.Forms.Shortcut. pre defined set.
such as:
System.Windows.Forms.Shortcut.CtrlS; for Ctrl + S.
if you wanted to add this to an event handler for a menu bar for e.g. you would do this for an Exit item with Ctrl + X as shortcut keys:
Menu.MenuItems.Add(new MenuItem("E&xit", new EventHandler(this.FileExit_Clicked), Shortcut.CtrlX));
where FileExit_Clicked is your event handling method.
|
|
|
|
|
If you want to catch Ctrl+S you can override ProcessCmdKey in your Form derived class, like this...
protected override bool ProcessCmdKey ( ref Message msg, Keys keyData )
{
const int WM_KEYDOWN = 0x100;
if ( msg.Msg == WM_KEYDOWN && keyData == ( Keys.Control | Keys.S ) )
{
MessageBox.Show("You have pressed Ctrl+S");
return true;
}
return base.ProcessCmdKey( ref msg, keyData );
} Hope that helps

The DataSet doesn't serialize its DataRelationship collection in my test case! In .NET 1.1, the docs clearly show the [Serializable] attribute, and in .NET 2.0, the docs have it missing!
What happened to being able to serialize the DataSet's relationships???
[edit]You have to set the "Nested" property of the DataRelation for it to serialize correctly with WriteXml.[/edit]

I'm kinda new to database programming in C#, so bear with me. I've done a search in my MSDN library documentation, and I've done a quick search through CP's articles, both to no avail. Can someone please tell me how to create a new mdb file from inside my code? (or point me in the right direction, to some informative article somewhere)
At the present time, I'm stuck making my mdb files in MS Access and then playing with them in code, but I'd like to create a new one from my code...
Thanks!
