如何抑制由代码，我不能改变显示一个对话框？(How to suppress a dialog box

我有一个第三方的一个进程内COM服务器。其中一个我称之为如果它捕获特定类型的错误会显示一个错误消息对话框的功能。这个问题是我想在批量处理数据，而我使用的数据源导致该错误对话框弹出了很多。这不会是一个问题，如果它产生了1000个对话框，而是它块和函数不返回，直到按下OK。

我怎样才能抑制从显示出来的对话框中，或以编程方式按OK？

这里是调用堆栈的副本，因为它是在等我按OK

我怀疑这将有助于（没有选项来禁用消息框，事件订阅，或其他重载的功能），但这里是调用代码。

for (int i = 1; i <= recordCount; i++)
{
    //If the dialog shows up the following line blocks till you press OK.
    var values = _comServer.GetValues(fileHandle, i); 

    sqlDataConsumer.LoadRow(values);
}

Answer 1:

一个消息框泵消息循环。这是东西，你可以利用的，它可以让你与注入Control.BeginInvoke（，一旦出现消息框上运行的代码）。然后，您可以使用该代码查找对话窗口并关闭它。添加一个新类到您的项目并粘贴此代码：

using System;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;

public class DialogCloser : IDisposable {
    public DialogCloser() {
        if (Application.OpenForms.Count == 0) throw new InvalidOperationException();
        Application.OpenForms[0].BeginInvoke(new Action(() => {
            // Enumerate windows to find dialogs
            if (cancelled) return;
            EnumThreadWndProc callback = new EnumThreadWndProc(checkWindow);
            EnumThreadWindows(GetCurrentThreadId(), callback, IntPtr.Zero);
            GC.KeepAlive(callback);
        }));
    }

    public void Dispose() {
        cancelled = true;
    }

    private static bool checkWindow(IntPtr hWnd, IntPtr lp) {
        // Checks if <hWnd> is a Windows dialog
        StringBuilder sb = new StringBuilder(260);
        GetClassName(hWnd, sb, sb.Capacity);
        if (sb.ToString() == "#32770") {
            // Close it by sending WM_CLOSE to the window
            SendMessage(hWnd, 0x0010, IntPtr.Zero, IntPtr.Zero);
        }
        return true;
    }

    private bool cancelled;

    // P/Invoke declarations
    private delegate bool EnumThreadWndProc(IntPtr hWnd, IntPtr lp);
    [DllImport("user32.dll")]
    private static extern bool EnumThreadWindows(int tid, EnumThreadWndProc callback, IntPtr lp);
    [DllImport("kernel32.dll")]
    private static extern int GetCurrentThreadId();
    [DllImport("user32.dll")]
    private static extern int GetClassName(IntPtr hWnd, StringBuilder buffer, int buflen);
    [DllImport("user32.dll")]
    private static extern IntPtr SendMessage(IntPtr hWnd, int msg, IntPtr wp, IntPtr lp);
}

用法示例：

private void button1_Click(object sender, EventArgs e) {
    using (new DialogCloser()) {
        // Replace this with the call to the COM server method:
        MessageBox.Show("you never see this");
    }
}
