The Click event is invalid for this ActiveX control

I use a proprietary IDE that is part of a large software package. At its core, however, C# is used as the language. Most .Net components and classes can be used. I can use it to create my own functions / WinForms, which are then integrated into an ERP system. This means that you can expand this system yourself. This is quite well implemented but there is no documentation and the support is also poor at this point. That's why I'm trying my luck here. Maybe someone can help.
I am currently programming a WinForms window that contains a WebBrowser control (wb). I'm pretty sure this is IE. I can programmatically create and include HTML code via MemoryStream (ms):
ms.Write(bytes, 0, bytes.Length);
wb.DocumentStream = ms;
It all works very well. Now I want to get events from the browser and have had the IDE create event handlers for this:
try {
wb.Click += new EventHandler(wb_Click);
...} etc.
public void wb_Click (object sender, EventArgs e)
{ }
The compiler shows no errors. During the execution I get the error message: The Click event is invalid for this ActiveX control. What could trigger this error? W. Wolf

Thanks for your tips! I was able to solve this with the following code:
...
HtmlElementCollection elements = wb.Document.GetElementsByTagName("span");
for (int n = 0; n < elements.Count;n++)
{
elements[n].Click += new HtmlElementEventHandler(el_Click);
}
...
public void el_Click (object sender, HtmlElementEventArgs e)
{
HtmlElement el = (HtmlElement) sender;
ShowInfo(el.Id);
}
I can continue to work with it.

c# idm using 'batch download from clipboard'(one of idm's functions)

I want to make a program using C# (Windows Forms App) that if I click a button, assume that there are some addresses that I want to download in my clipboard already, then using 'batch download from clipboard' function, start downloading with IDM.
Anybody please help me to make it.
Batch download from clipboard

you should let operating system to decide which program to run. it will open a default browser and if the address has some file to download it will open your IDM.in "if" section, you can add some checking to see if the address ends with the extension you wanna download . The code-behind will be something like this
private void button1_Click(object sender, EventArgs e)
{
var clipboard = Clipboard.GetText();
if (clipboard.StartsWith("http://"))
{
System.Diagnostics.Process.Start(clipboard);
}
}

Sharing from Windows Phone 8

I am working on a Windows Phone 8 app and am trying to share content through the DataTransferManager. The Windows API documentation says it is supported in Windows Phone but when the DataTransferManager.GetForCurrentView() function is called I get an exception
System.NotSupportedException was unhandled by user code
HResult=-2146233067
Message=Specified method is not supported.
Source=Windows
InnerException:
I have been searching for an answer and can't find anyone else with the same issue, any help would be appreciated. All samples on this topic seem to be Windows 8 specific, but Phone 8 does include these functions. Here's sample code from my app.
protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
DataTransferManager dataTransferManager = DataTransferManager.GetForCurrentView();
dataTransferManager.DataRequested += new TypedEventHandler<DataTransferManager, DataRequestedEventArgs>(dataTransferManager_DataRequested);
}
private void dataTransferManager_DataRequested(DataTransferManager sender, DataRequestedEventArgs e)
{
DataPackage requestData = e.Request.Data;
requestData.Properties.Title = "Share Text Example";
requestData.Properties.Description = "An example of how to share text.";
requestData.SetText("Hello World!");
}
private void Button_Tap_1(object sender, System.Windows.Input.GestureEventArgs e)
{
DataTransferManager.ShowShareUI();
}
Again, the exception is shown when the page loads on the DataTransferManager.GetForCurrentView(); function so it doesn't get to the other lines, but included them anyway. I've tried adding/removing permissions and assemblies but must be missing something. I've also tried putting the function in different events (such as the onTap function) with the same results.
If anyone is interested in trying this on their own here is some documentation:
DataTransferManager
DataRequested
DataPackage
GetForCurrentView()
UPDATE
Although it may not be the best solution given the context of this question, I am implementing the Email/Sms/Link Tasks as described below rather than using the DataTransferManager. It seems that DataTransferManager may not be accessible in WP8 and although the tasks will take a number of different functions they seem to be the best way to perform the intended functionality.

I think I have found most of what I was looking for with Launchers... Rather than just using the Windows 8 general sharing functionality I can be specific with Tasks/Launchers.
Unfortunately it doesn't have as many sharing options as the charm does, I will be implementing several functions for email/sms/social but so far this is the best solution.
Here are the functions that I will be implementing
private void ShareLink(object sender, System.Windows.Input.GestureEventArgs e)
{
ShareLinkTask shareLinkTask = new ShareLinkTask()
{
Title = "Code Samples",
LinkUri = new Uri("http://msdn.microsoft.com/en-us/library/windowsphone/develop/ff431744(v=vs.92).aspx", UriKind.Absolute),
Message = "Here are some great code samples for Windows Phone."
};
shareLinkTask.Show();
}
private void ShareEmail(object sender, System.Windows.Input.GestureEventArgs e)
{
EmailComposeTask emailComposeTask = new EmailComposeTask()
{
Subject = "message subject",
Body = "message body",
To = "recipient#example.com",
Cc = "cc#example.com",
Bcc = "bcc#example.com"
};
emailComposeTask.Show();
}
private void ShareSMS(object sender, System.Windows.Input.GestureEventArgs e)
{
SmsComposeTask smsComposeTask = new SmsComposeTask()
{
Body = "Try this new application. It's great!"
};
smsComposeTask.Show();
}

Share Link Task

According to my API reference, DataTransferManager is reserved for native apps only. Windows Phone API Quickstart.

Have you tried using the fully qualified method? It would be something like this:
DataTransferManager dataTransferManager = indows.ApplicationModel.DataTransfer.DataTransferManager.getForCurrentView();
Also, make sure your target is Windows Phone 8.

The Windows 8 Share Contract isn't supported on WP8. There isn't even a Share charm on WP8. Why are you trying to use the DataTransferManager?
Instead of using the Share Contract, most usecases can work just fine with WP8 app2app custom protocols and file extensions. Using WP8 app you can transfer files and data across apps. Althrough the standardized contract of the Share Contract is gone, apps can create their own contracts using custom protocols and file extensions.
Here for example you can learn more about a real-world 3rd party implementation of Nokia Music custom protocols.

Cannot display webcam Using Aforge.NET in C#

I am currently working on a project where I need to simply display the users webcam on a
asp.image object. I am using the Aforge frame work and have gotten it to work on a windows app. In the windows app I would set up the video source variable equal to the image property of a picture box
In other words:
samplepicturebox1.image = videosource
The problem is, for asp there is only a asp:image object and the only property is .imageurl
imgSource.imageurl = ???
How would I go forth and link a video stream object to the image url or what other object would I use to display the stream? I have looked into putting an output on a seperate aspx.cs file so I could just use that as a imageurl but had no luck.
Here is my code to specify:
//using AForge.Video;
//using AForge.Video.DirectShow;
//using System.Drawing.Imaging;
public partial class WebForm1 : System.Web.UI.Page
{
private FilterInfoCollection VideoCaptureDevices;
private VideoCaptureDevice FinalVideo;
protected void Page_Load(object sender, EventArgs e)
{
drpSource.Items.Clear();
VideoCaptureDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice);
foreach (FilterInfo VideoCaptureDevice in VideoCaptureDevices)
{
drpSource.Items.Add(VideoCaptureDevice.Name);
}
drpSource.SelectedIndex = 0;
}
protected void btnStart_Click(object sender, EventArgs e)
{
FinalVideo = new VideoCaptureDevice(VideoCaptureDevices[drpSource.SelectedIndex].MonikerString);
FinalVideo.NewFrame +=new NewFrameEventHandler(FinalVideo_NewFrame);
FinalVideo.Start();
}
void FinalVideo_NewFrame(object sender, NewFrameEventArgs deventArgs)
{
imgSource.ImageUrl=(FinalVideo.ToString());
}
}
I have also populated a combo box with the user's different video source. That also displays correctly
I really appreciate any help. This will translate into communications. I want to be able to stream between users just like Omegle and Chatroulette. If anyone would recommend a better framework to look into I'm open, I've only looked into Aforge and Touchless as two C# frameworks that support video streaming.
I've seen many use flash and I do know a bit of ActionScript, but to be completely honest, I'd rather not mess too much with flash as ActionScript is quite the pain and from my opinion in some aspects, flash slowly withering and dieing.

#KeithNicholas is correct. A web application is not the same as a client/winforms application. A web app is run in the webserver and not in the web browser.
It got no access to the user's webcam. You need to use a client side technology like flash or silverlight to be able to use the webcamera from the server.

Is it possible to open a PDF inside a c# application with Acrobat.dll?

I know that I can display a PDF file in my c# executable (not web app) with:
private AxAcroPDFLib.AxAcroPDF axAcroPDF1;
axAcroPDF1.LoadFile(#"somefile.pdf");
axAcroPDF1.Show();
But that is the regular pdf viewer like in the browser. I don't want that. I want full Adobe Standard or Professional functionality in my C# application using the Adobe controls. For example, if I use the code above, it loads in the C# app and I can see the adobe toolbar (print, save, etc.) But it is useless to me because I need things like save which cannot be done with the activex viewer above. Specifically, you cannot save, just as you cannot within the broswer.
So, I referenced the acrobat.dll and am trying to use:
Acrobat.AcroAVDocClass _acroDoc = new Acrobat.AcroAVDocClass();
Acrobat.AcroApp _myAdobe = new Acrobat.AcroApp();
Acrobat.AcroPDDoc _pdDoc = null;
_acroDoc.Open(myPath, "test");
pdDoc = (Acrobat.AcroPDDoc)(_acroDoc.GetPDDoc());
_acroDoc.SetViewMode(2);
_myAdobe.Show();
It opens adobe acrobat but it opens it outside of my c# application. I need it to open in my c# application like the activex library does. Can it be done with these libraries?
If I cannot open it in my c# application I would like to be able to "hold" my c# app tied to it so the c# app knows when I close the adobe app. At least that way I'd have some measure of control. This means I would hit open, the adobe app opens. I close the adobe app, my C# app is aware of this and loads the newly changed doc with the activex library (because I don't need change ability anymore, just displaying.)
I have the full versions of adobe acrobat installed on my computer. It is not the reader.
Thank you for any help.
edit:
There is an example in vb in the adobe acrobat sdk. I believe it is called activeview.

you can check out ABCpdf. I dont know if it has this capability but we have used it for several of our apps

Using a webbrowser control would be an option to display the content.

IText# may help you out.
You can create PDF's and I believe you can use it to read and modify them.
As for displaying in the app..... I am not sure how to display them with iText or if it is possible (have not tried this yet), sorry. iText does let you convert to RTF which may be one approach.

Best option is to write a listener which tells your calling code when Adobe.exe is no longer running. Something like the following (with tweaks for your uses) should work:
public void Open(string myPath)
{
Acrobat.AcroAVDocClass _acroDoc = new Acrobat.AcroAVDocClass();
Acrobat.AcroApp _myAdobe = new Acrobat.AcroApp();
Acrobat.AcroPDDoc _pdDoc = null;
_acroDoc.Open(myPath, "test");
_pdDoc = (Acrobat.AcroPDDoc) (_acroDoc.GetPDDoc());
_acroDoc.SetViewMode(2);
_myAdobe.Show();
NotifyAdobeClosed += new EventHandler(Monitor_NotifyAdobeClosed);
MonitorAdobe();
}
private void Monitor_NotifyAdobeClosed(object sender, EventArgs e)
{
NotifyAdobeClosed -= Monitor_NotifyAdobeClosed;
//Do whatever it is you want to do when adobe is closed.
}
private void MonitorAdobe()
{
while(true)
{
var adcount = (from p in Process.GetProcesses()
where p.ProcessName.ToLower() == "acrobat"
select p).Count();
if (adcount == 0)
{
OnNotifyAdobeClosed();
break;
}
}
}
public event EventHandler NotifyAdobeClosed;
public void OnNotifyAdobeClosed()
{
if (NotifyAdobeClosed != null)
NotifyAdobeClosed(this, null);
}
