I have installed Nevron for evaluation and I now wish to uninstall it. However, after I remove Nevron I receive the following message when I try to acces the designer code in my project Windows Forms:

To prevent possible data loss before loading the designer, the following errors must be resolved:

I urgently need to have my program run without Nevron, please help me fix this.

Thanks

Hi Elena,

Most likely you uninstalled the product before you clean up the form which uses it. This will confuse the designer as it is not able to find all types referenced by the form. To fix this you need to manually clean up all designer generated code and resources related to the control found in Form.Designer.cs (or the like). Typically the code you need to delete looks like:

this.nChartControl1 = new Nevron.Chart.WinForm.NChartControl();
...
//
// nChartControl1
//
this.nChartControl1.AutoRefresh = false;
this.nChartControl1.BackColor = System.Drawing.SystemColors.Control;
this.nChartControl1.InputKeys = new System.Windows.Forms.Keys[0];
this.nChartControl1.Location = new System.Drawing.Point(12, 5);
this.nChartControl1.Name = "nChartControl1";
this.nChartControl1.Size = new System.Drawing.Size(461, 318);
this.nChartControl1.State = ((Nevron.Chart.WinForm.NState)(resources.GetObject("nChartControl1.State")));
this.nChartControl1.TabIndex = 1;
this.nChartControl1.Text = "nChartControl1";

...
this.Controls.Add(this.nChartControl1);
...

private Nevron.Chart.WinForm.NChartControl nChartControl1;

In addition you can view the resource file generated by the designer (like Form1.resx) and remove all appearances of nChartControl(N).State there.

As a last resort you can simply recreate the form.
