I have a ActiveX control which is controlling a specific machine.
For recycling this ActiveX control, our machine vendor uses winform in C#

If I attach this ActiveX control to Winform in C#, it is well operated
and also easy job.

Please refer below code

private void InitializeComponent()
        {
            System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(Form1));
            this.traceView = new AxHxTraceViewLib.AxHxTraceView();
            this.runControl = new AxHXHSLRUNCONTROL2Lib.AxHxHSLRunControl();
            this.button1 = new System.Windows.Forms.Button();
            ((System.ComponentModel.ISupportInitialize)(this.traceView)).BeginInit();
            ((System.ComponentModel.ISupportInitialize)(this.runControl)).BeginInit();
            this.SuspendLayout();
            // 
            // traceView
            // 
            this.traceView.Enabled = true;
            this.traceView.Location = new System.Drawing.Point(156, 18);
            this.traceView.Name = "traceView";
            this.traceView.OcxState = ((System.Windows.Forms.AxHost.State)(resources.GetObject("traceView.OcxState")));
            this.traceView.Size = new System.Drawing.Size(638, 249);
            this.traceView.TabIndex = 3;
            // 
            // runControl
            // 
            this.runControl.Enabled = true;
            this.runControl.Location = new System.Drawing.Point(26, 12);
            this.runControl.Name = "runControl";
            this.runControl.OcxState = ((System.Windows.Forms.AxHost.State)(resources.GetObject("runControl.OcxState")));
            this.runControl.Size = new System.Drawing.Size(96, 198);
            this.runControl.TabIndex = 0;
            // 
            // button1
            // 
            this.button1.Location = new System.Drawing.Point(652, 273);
            this.button1.Name = "button1";
            this.button1.Size = new System.Drawing.Size(142, 21);
            this.button1.TabIndex = 4;
            this.button1.Text = "Load Method";
            this.button1.UseVisualStyleBackColor = true;
            this.button1.Click += new System.EventHandler(this.button1_Click);
            // 
            // Form1
            // 
            this.AutoScaleDimensions = new System.Drawing.SizeF(7F, 12F);
            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
            this.ClientSize = new System.Drawing.Size(806, 306);
            this.Controls.Add(this.button1);
            this.Controls.Add(this.traceView);
            this.Controls.Add(this.runControl);
            this.Name = "Form1";
            this.Text = "Form1";
            this.Load += new System.EventHandler(this.Form1_Load);
            ((System.ComponentModel.ISupportInitialize)(this.traceView)).EndInit();
            ((System.ComponentModel.ISupportInitialize)(this.runControl)).EndInit();
            this.ResumeLayout(false);
        }

Unfortunately It is not that I want to do.
As you know, Winform have UI element(it has form)
But I don't want to show UI element when I use this ActiveX Control.

I think it would be console code.

Are there anyone who knows a solution for this problem??

Detailed source is good.
But just simple keywords of technic or subject are OK.

Please Help me.

I appreciate this question.

Really, why not using an ActiveX control without a UI?
This is a general problem, that there are too many components created as controls only to please the addicts of design-time developers, even though the functionality takes no space in the graphical layout.

You may or may not be able to use your control without UI; it depends on the features of the component you want to use. At least you can try. The idea is to make an interop ActiveX assembly (one can do it manually using AxImp tool) reference it in your project and instantiate the object(s) in a regular way, without making it a child of a form.
