Sometimes users cannot install Image Uploader ActiveX due to security restrictions applied on their computers by security policies of companies. As a solution we suggest enable installation progress which can detect this situation and give users information how to work it around (they need to download resditributable package of Image Uploader and install it manually). The details on this approach can be found in the Using Image Uploader Installation Progress topic.

The sample in this article gives another approach. If Image Uploader ActiveX cannot be installed standard HTML form (with “browse” and “upload” buttons) is displayed allowing users upload files one by one using standard browser functionality.

Additionally this sample demonstrates two more features. Here are full set of features demonstrated by this sample:
  1. How to upload entire folders with subfolders to the server.
  2. How to determine if the user fails to install ActiveX and show a basic upload fields instead of Image Uploader.
  3. How to configure automatic resume of the upload if it is interrupted.

I've made improvements for the previous demo. Now you do not need to manually set instructionsHtml property:
// Add "Browse" fields which will be shown if ActiveX fails.
writer.instructionsHtml = '<div><input type="file" name="file" /><input type="submit" value="Upload" name="submitButton" /></div>';

Instead you only need to put fallback content inside SimpleUploadPanel panel:
<asp:Panel runat="server" ID="SimpleUploadPanel">
    <asp:FileUpload ID="FileUpload1" runat="server" />
    <asp:Button ID="Button1" runat="server" Text="Upload" onclick="Button1_Click" />

And this content will be shown if ActiveX installation fails.
