copied!<p>I have created a "Windows Form" and a second "Thread" .</p> <ul> <li><p>My form has a button that changes the value of a variable .</p></li> <li><p>My second thread uses an unstoppable loop to analyze that variable .</p></li> </ul> <p>So this is an event that Changes the text of the form when the value of a that variable changes , but I cannot have my form or any of controls in the blocks of that "ThreadProcess" function because it is declared after that .</p> <p>I also cannot declare my form before it because I need to use "ThreadClass" in form constructor . What should I do then ?</p> <pre><code>using namespace System; using namespace System :: Threading; using namespace System :: Windows :: Forms; namespace Program { static int Number = 0; ref class ThreadClass { public : void ThreadProcess () { int SavedNumber = Number; while (1) { if(Number != SavedNumber) { this -> Text = "Changed"; SavedNumber = Number; } else this -> Text = "Nothing Yet"; } } } ; ref class MainForm : Form { Button ^ ChangeButton; Thread ^ EventThread; ThreadClass ^ EventThreadClass; public : MainForm () { EventThreadClass = gcnew ThreadClass ; EventThread = gcnew Thread ( gcnew ThreadStart ( EventThreadClass, & ThreadClass :: ThreadProcess ) ) ; EventThread -> IsBackground = true; ChangeButton = gcnew Button (); ChangeButton -> Click += gcnew EventHandler (this, & MainForm :: CloseButtonEventProcess); Controls -> Add (ChangeButton); EventThread -> Start (); } void CloseButtonEventProcess (Object ^ Sender , EventArgs ^ EA) { Number ++; } } ; } </code></pre>
