Richtextbox

[Nathan Carroll]

In an mdi environment I constructed a child for with a richtextbox control
that is used to load .rtf's. This works fine on the intiatial load of the
form but when for is closed and reopened later I get:

System.ObjectDisposedException: Cannot access a disposed object named
"RichTextBox".
Object name: "RichTextBox".
at System.Windows.Forms.Control.CreateHandle()
at System.Windows.Forms.TextBoxBase.CreateHandle()
at System.Windows.Forms.Control.get_Handle()
at System.Windows.Forms.RichTextBox.StreamIn(Stream data, Int32 flags)
at System.Windows.Forms.RichTextBox.LoadFile(Stream data,
RichTextBoxStreamType fileType)
at System.Windows.Forms.RichTextBox.LoadFile(String path,
RichTextBoxStreamType fileType)
at System.Windows.Forms.RichTextBox.LoadFile(String path)
at CompAid.frmSpecRules.bm_PositionChanged(Object sender, EventArgs e) in
c:\vsprojects\compaid\frmspecrules.cs:line 237

I constucted the same process previously in VB.net and it never came up with
this error. Should window form applications be built in VB.net?

Nathan,

I have seen the richtextbox expert from the VBNet newsgroup strangly enough
not some days, maybe you can look yourself what he wrote about this.
