[Exception] Class not registered

[usamaalam]

Hello everybody,

I am getting following exception while opening a form in a separate thread.

An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in system.windows.forms.dll

Additional information: Class not registered

Exception throws on following line in InitializeComponent() method.

this.Load += new System.EventHandler(this.frm_DesingTemplate_Load);
			((System.ComponentModel.ISupportInitialize)(this.axDrawingControl1)).EndInit();

Here is the code for sending methods on thread.

		private void PrintAndDraw(bool IsDrawDrawing,bool IsPrintReport)
		{
			try
			{
				if(IsPrintReport)
				{
					ThreadStart reportThreadStart = new ThreadStart(PrintWorkOrder);
					Thread reportThread = new Thread(reportThreadStart);
					reportThread.Start();
				}
				
				if(IsDrawDrawing)
				{
					ThreadStart drawingThreadStart = new ThreadStart(DrawDrawing);
					Thread drawingThread = new Thread(drawingThreadStart);
					drawingThread.Start();
				}				
			}
			catch(Exception ex)
			{
				MessageBox.Show(ex.Message);
			}
		}

Here is the method under which exception is thrown.

		private void DrawDrawing()
		{
			long ComplaintCode = Convert.ToInt64(this.clsComplaintCode);
			int ModelCode = Convert.ToInt32(this.cboMCModel.SelectedValue);
			int ManufacturerCode = Convert.ToInt32(this.cboMCManufacturer.SelectedValue);
			string strWOrder = txtMCWorkOrder.Text; 

			frm_DesingTemplate frmComp = new frm_DesingTemplate(ComplaintCode , ModelCode, ManufacturerCode, strWOrder);
			frmComp.Show(); 		
		}

Exception is thrown in the InitializeComponent() of frm_DesingTemplate form. A visio drawing control has been used on this form.

Any ideas to resolve this issue ??

Thanks.
