Invoke On Target

Tired of always checking if you need to invoke or not on a thread. This method below will invoke the specified delegate on the specified target with the passed arguments.

/// Invokes the specified delegate on the specified target with the specified arguments.
/// The delegate to invoke.
/// The target for the invocation.
/// The arguments for the invoke.
private void invokeOnTarget(Delegate del, ISynchronizeInvoke target, params object[] args)
    //if target requires invoke.
    if (target.InvokeRequired)
        //invoke the delegate on the target
        target.BeginInvoke(del, args);
        //invoke the delegate on this thread

C# Cross Thread Exception on Subform

I was having an issue where I had a textbox control on a sub form and calling after an update would cause a cross thread exception (even using invoke). The problem was I created a subform (with the textbox control) and added text to the textbox before the sub form was displayed. The problem is that the handle for the control was not created yet and invokerequired was false because of this. Thus the thread that updated my control actually caused the control’s handle to be created. When I called the, it would try to access the control on the GUI thread and not the thread that had created it. See below:


Subform _Sub
Public MainForm()
    _Sub = new Subform();
    // Sub form’s handle is not created yet.
// If this method is called  on a different thread before the sub form (show) is
// called on the GUI thread, a cross thread exception can occur.
// -This method will append to a text box on the sub form.
private void appendToSubForm(string text)
        //  Invoke will not be required since the handle has not yet been created.
        if (_Sub.InvokeRequired)
            _ Sub.Invoke((Action)appendToDebugLog, text);
            if (_Sub == null || _ Sub.IsDisposed)
            // This method which will append to textbox will cause the sub form’s handle to be created
            // on the thread this method is called on.
// Call this.CreateHandle() on the Sub form in order to force creation of the handle when the constructor is called.
// Required to create the handle on the thread that the constructor is called on.
// In our case, the GUI thread.  This prevents cross threading if the handle
// is created on a non GUI thread.

C# Scroll To End Text Box

After appending text to a text box, you may want to scroll to the end of that box. Here’s some code that will accomplish this (remember to include, System.Runtime.InteropServices in your using header):

/// Function import to automatically scroll down rich text boxes.
/// handle to destination window
/// message
/// first message parameter
/// second message parameter
public static extern int SendMessage(
IntPtr hWnd, // handle to destination window
int Msg, // message
IntPtr wParam, // first message parameter
IntPtr lParam // second message parameter

/// Automatically scroll down rich text boxes.
/// The windows handle of a text box.
public void ScrollToEnd(IntPtr Handle)
int WM_VSCROLL = 0x115;
int SB_BOTTOM = 7;
SendMessage(Handle, WM_VSCROLL, (IntPtr)SB_BOTTOM, IntPtr.Zero);

// Using the method.
