Hello ,

I want a good and easy tutorial of how to compile and build the final package.

It should contain:
1. EXE file
2. Needed Dll's.
3. Few Wavs (sound) files.

cannot find out if the threads in the default System.Threading.ThreadPool have ended.

To do this, you can roll your own like Ami Bar[^] does in this article[^].

fire a parent control events from its childs events

Hi friends
In my c# project I have a Main form with a panel1 on it and a user control named Thumbs in the solution ,
The panel1 hosting instances of thumbs as its child controls .the problem is that when mouse clicks on the
child controls of panel1 the Panel1_click event not fires but this works when the mouse locates between
the thumbs (gap erea) , so the question would be How is possible to fire a parent control event(here panel1)
from its child controls(here thumbs) events?
Please If some of you knows ho to get trough let me know with some code if possible.

thanks.

You can subscribe the Panel to the child Thumbs' Click event. Then, when the Thumb get clicked, the Panel will know about it and you can call its OnClick method.

Note, to do this, you'll need to subclass Panel.

Hi! I need to display math equations in C# application. Unfortunately, seems like Microsoft Equation editor files (EXE and DLL) are not COM components, so i can't add it in VS controls toolbox. Does anyone have idea how to acomplish this?

Any other idea (not using Microsoft Equation)?

Thanks in advance!

DataAccessors

Ive got a problem. i have made a classlibrary with dataclasses and a classlibary with data-accessorclasses (in which i use sqlqueries to get data from an sqldatabase). i try to import these classes in a webservice.
When i type "using DataClasses" (the dataclasses library), there isno problem at all.
But when i type "using DataAccessors" it doesnt recognises it. I've added the references, so that's not the problem. I also tried changing the name, but thats no problem either...
Any ideas?

Thx, Peter

Are you really sure that you want to do that? I would be pretty pissed if I ran a program and found out that it had changed my user settings.

Isn't it the default culture of the current thread that you want to change?

Access controls from Thread

When program loads I start new thread which tries to connect some DB server.
this.Load += new EventHandler(Labels_Load);

private void Labels_Load(object obj, EventArgs ea)
{
    Thread th = new Thread(new ThreadStart(myconnect));
    th.Start();
}

And I need to load some data to comboBox lastBookings. Is it possible to access some form controls from Threads ?

private void myconnect()
{
    mysql.mySqlConnect("localhost", "mydb", "usr", "psw");
    // ... some code here ...
    lastBookings.DataSource = new string[] { "dsdf", "dsfsd ", "dsfa" };       
}

I make a new thread because often there is no connection to DB server. And all net operations (if server is not availiable) slow up programm very much.

no, dont work, but if I do the same:
lastBookings.DataSource = new string [] { "dsdf", "dsfsd ", "dsfa" };
not from a thread all works good.

The core rule is that you are not allowed to modify UI elements from outside the thread they were created in.

The way to go is to use Invoke or BeginInvoke in this case. Invoke performs the method call synchronously, BeginInvoke is asynchronous.

thank you very much! It helped me very much.
In my example it must be so (if someone will have the same question):

private void UpdateBookings(string[] str)
{
    lastBookings.DataSource = str;    
}

public delegate void UpdateBookingsCallback(string[] str);
    
private void myconnect()
{
    string[] comboElements = {"el1", "el2", "el3" };
    
    lastBookings.Invoke(new UpdateBookingsCallback(this.UpdateBookings), new object[] { comboElements });
}
