Kann mein Formular im Formular-Designer nicht anzeigen

Question

Ich habe eine neue Klasse zu meinem C# -Projekt hinzugefügt. Sehr einfach und basiert auf vielen Beispielen habe ich gefunden:

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 
using System.Windows.Forms; 

namespace GENIO_Viewer 
{ 
    class DBTableLayoutPanel : TableLayoutPanel 
    { 
     public DBTableLayoutPanel() : base() 
     { 
      DoubleBuffered = true; 
     } 
    } 
} 

ich bearbeitet dann die Designer Klassendatei die überarbeitete Objekt zu verwenden (Code abgeholzt):

private void InitializeComponent() 
{ 
    this.tableLayoutPanel = new DBTableLayoutPanel(); 
    // tableLayoutPanel 
    // 
    this.tableLayoutPanel.AutoSize = true; 
    this.tableLayoutPanel.BackColor = System.Drawing.Color.Black; 
    this.tableLayoutPanel.ColumnCount = 1; 
    this.tableLayoutPanel.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent, 50F)); 
    this.tableLayoutPanel.Cursor = System.Windows.Forms.Cursors.Cross; 
    this.tableLayoutPanel.Dock = System.Windows.Forms.DockStyle.Fill; 
    this.tableLayoutPanel.Location = new System.Drawing.Point(0, 24); 
    this.tableLayoutPanel.Name = "tableLayoutPanel"; 
    this.tableLayoutPanel.RowCount = 1; 
    this.tableLayoutPanel.RowStyles.Add(new System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Percent, 50F)); 
    this.tableLayoutPanel.Size = new System.Drawing.Size(555, 359); 
    this.tableLayoutPanel.TabIndex = 4; 
} 

Es kompiliert OK. Aber wenn ich gehe teh Form im Editor angezeigt bekomme ich ein Problem:

Warum ist das? Ich kann nicht herausfinden, was ich tun muss, um es zu reparieren.

Update:

Dies ist voll Formulardefinition für die Designer-Datei. Es funktioniert nur, wenn ich die DBTableLayoutPanel Zeilen auskommentiere und durch die auskommentierten Zeilen ersetze. Verwirrt. :

using System;

{ 
    partial class GENIO_Viewer_Form 
    {

     protected override void Dispose(bool disposing) 
     { 
      if (disposing && (components != null)) 
      { 
       components.Dispose(); 

       m_moduleTD_Tb.Dispose(); 
       m_hostApp.Dispose();

Answer 1

ich auf diese Frage kam:

Cannot Place User Control on Form

In einem der Antworten, die es über das Ändern der Build-Modus sprach. Ich hatte es auf x64 Bit-Build-Modus wegen der DLL-Dateien festgelegt, von denen meine Anwendung abhängt. Wenn auf Jede CPU Ich erhalte diese Fehler zu bauen:

This mismatch may cause runtime failures. Please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the processor architectures between your project and references, or take a dependency on references with a processor architecture that matches the targeted processor architecture of your project.

So ist es fiel mir ein, die Anwendung zurück zu Any CPU zu setzen, führen Sie eine saubere und neu zu erstellen, und voila, kann ich jetzt meine Formulare bearbeiten. Aber ich muss es danach auf x64 zurücksetzen. Es ist nervig. Aber ich sehe keinen anderen Weg.
