嵌入一​​个简单的ActiveX控件得到Class not Registered错误

Question

我刚刚开发了一个非常简单的ActiveX控件（使用VS.NET向导，甚至不更改一行），并编译它。运行“regsvr32 ax1.ocx”后，我创建了一个新的C＃WinFrom项目并将ActiveX控件拖到表单中。然后我构建并运行它，错误说：

Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))

内线：

((System.ComponentModel.ISupportInitialize)(this.axax11)).EndInit();

整个功能是：

    private void InitializeComponent()
    {
        System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(Form1));
        this.axax11 = new Axax1Lib.Axax1();
        ((System.ComponentModel.ISupportInitialize)(this.axax11)).BeginInit();
        this.SuspendLayout();
        // 
        // axax11
        // 
        this.axax11.Enabled = true;
        this.axax11.Location = new System.Drawing.Point(103, 90);
        this.axax11.Name = "axax11";
        this.axax11.OcxState = ((System.Windows.Forms.AxHost.State)(resources.GetObject("axax11.OcxState")));
        this.axax11.Size = new System.Drawing.Size(100, 50);
        this.axax11.TabIndex = 0;
        // 
        // Form1
        // 
        this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
        this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
        this.ClientSize = new System.Drawing.Size(284, 262);
        this.Controls.Add(this.axax11);
        this.Name = "Form1";
        this.Text = "Form1";
        ((System.ComponentModel.ISupportInitialize)(this.axax11)).EndInit();
        this.ResumeLayout(false);

    }

我假设您在非托管C ++代码中编写了ActiveX控件。您需要创建此控件的64位版本，或者需要强制使用它的.NET程序以32位模式运行。后者是更快的修复，Project + Properties，Build选项卡，Platform Target = x86。
