如何诊断原因、修复或处理与adobe activex/com相关的错误0x80004005?

好吧,回去回答我自己的问题。

该问题与“首选项”>“Internet”中的“在浏览器中显示PDF”设置直接相关。 选中此选项后,问题就消失了。如果不检查,它就会回来。

下面是我们建议如何以编程方式处理它:

    private string defaultPdfProg()
    { //Returns the default program for opening a .pdf file; On Fail returns empty string. 
      // (see notes below) 
        string retval = "";

        RegistryKey pdfDefault = Registry.ClassesRoot.OpenSubKey(".pdf").OpenSubKey("OpenWithList");
        string[] progs = pdfDefault.GetSubKeyNames();
        if (progs.Length > 0)
        {
            retval = progs[1];
            string[] pieces = retval.Split('.'); // Remove .exe

            if (pieces.Length > 0)
            {
                retval = pieces[0];
            }
        }

        return retval;
    }

    private void browserIntegration(string defaultPdfProgram)
    { //Test if browser integration is enabled for Adobe Acrobat (see notes below)
        RegistryKey reader = null;
        string[] vers = null;

        if (defaultPdfProgram.ToLower() == "acrobat")
        { //Default program is Adobe Acrobat
            reader = Registry.LocalMachine.OpenSubKey("Software").OpenSubKey("Adobe").OpenSubKey("Adobe Acrobat");
            vers = reader.GetSubKeyNames();
        }
        else if (defaultPdfProgram.ToLower() == "acrord32")
        { //Default program is Adobe Acrobat Reader
            reader = Registry.LocalMachine.OpenSubKey("Software").OpenSubKey("Adobe").OpenSubKey("Acrobat Reader");
            vers = reader.GetSubKeyNames();
        }
        else
        {
            //TODO: Handle non - adobe .pdf default program
        }

        if (vers.Length > 0)
        {
            string versNum = vers[vers.Length - 1].ToString();
            reader = reader.OpenSubKey(versNum);
            reader = reader.OpenSubKey("AdobeViewer",true);

            Boolean keyExists = false;
            Double keyValue = -1;
            foreach(string adobeViewerValue in reader.GetValueNames())
            {
                if (adobeViewerValue.Contains("BrowserIntegration"))
                {
                    keyExists = true;
                    keyValue = Double.Parse(reader.GetValue("BrowserIntegration").ToString());
                }
            }

            if (keyExists == false || keyValue < 1)
            {
                string message = "This application requires a setting in Adobe to be changed. Would you like to attempt to change this setting automatically?";
                DialogResult createKey = MessageBox.Show(message, "Adobe Settings", MessageBoxButtons.OKCancel, MessageBoxIcon.Question, MessageBoxDefaultButton.Button1);
                if (createKey.ToString() == "OK")
                {
                    reader.SetValue("BrowserIntegration", 1, RegistryValueKind.DWord);
                    //test to make sure registry value was set
                }
                if (createKey.ToString() == "Cancel")
                {
                    //TODO: Provide instructions to manually change setting
                }
            }
        }
    }

需要注意的几点:

• 根据这两篇文章,密钥可能位于注册表中的两个不同位置(Originals vs Adobeviewer): http://support.adobe.com/devsup/devsup.nsf/docs/51722.htm http://support.adobe.com/devsup/devsup.nsf/docs/53556.htm

是否有人知道这些位置是否在所有版本中都可以互换,或者根据Acrobat的特定版本,注册表项是否在不同的位置?读者和杂技演员遵循同样的逻辑吗?

• 除了windows文件关联,adobe是否使用其他方法来确定“打开pdf文件的默认adobe应用程序”?我这样问是因为,如果您有一个非Adobe产品,例如作为默认文件关联应用程序安装的Foxit,但是在同时安装了Reader和Acrobat的计算机上使用ActiveX控件for Adobe,则使用什么逻辑来决定COM对象将与哪个应用程序对话?

对于我的系统(WindowsXP,AdobeReader9.3.2),你的解决方案没有成功(但是给了我足够的灵感,谢谢!!)

private void browserIntegration(string defaultPdfProgram)
    {
        try
        {
            RegistryKey reader = null;
            string[] vers = null;

            #region Walters Versuch
            reader = Registry.CurrentUser.OpenSubKey("Software").OpenSubKey("Adobe");
            reader = reader.OpenSubKey("Acrobat Reader");
            vers = reader.GetSubKeyNames();
            if (vers.Contains<string>("9.0"))
            {
                reader = reader.OpenSubKey("9.0");
                reader = reader.OpenSubKey("Originals", true);
                if (reader.GetValueNames().Contains<string>("bBrowserIntegration"))
                    reader.SetValue("bBrowserIntegration", 1, RegistryValueKind.DWord);
                // wenn der Key fehlt ist Browserintegration auch angeschaltet
                // alternativ: reader.DeleteSubKey("bBrowserIntegration", false);
            }
            else
                MessageBox.Show(
                    "In case you run into problems later, please make sure yourself to select\n'Show PDF in Browser' in Acrobat Reader's Settings"
                    , "Unknown Version of Acrobat Reader");

            #endregion
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message + "\n" + ex.StackTrace
                + "\nIn case you run into problems later, please make sure yourself to select\n'Show PDF in Browser' in Acrobat Reader's Settings"
                , "Error while switching on 'Browserintegration' in 'Acrobat Reader'");
        }
}

非常感谢!

我只想补充一点,我也可以用Adobe Reader Xi来再现行为。 (Windows XP 32位-VB.NET 2005。)

注册表项是(*):

HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\11.0\Originals\bBrowserIntegration

如果该键值为1,则ActiveX组件已正确实例化。如果该键值为0,则在表单实例化时会出现异常。

我无法在Adobe Reader XI Internet属性页中找到浏览器集成选项。
