Error on InsertImage

[CindyB]

Hello, I’m doing mailmerge with regions using Aspose.Words for .NET, and I’m getting a “WebException occurred” error when calling

builder.InsertImage(imageFileName, width, height);

The specific error is: The remote server returned an error: (404) Not Found.

I need to programmatically return false if the image cannot be found or is not successfully inserted. I’ve tried using a try block and if/else statements with no luck. How can I capture and handle the 404 error?

Thank you in advance!

Hi

Thanks for your request. You can try using the following code:

public void Test064()
{
    Document doc = new Document();
    DocumentBuilder builder = new DocumentBuilder(doc);
    InsertImageFromURL(builder, "http://www.aspose.com/Images/aspose-logo.jpg", 250, 100);
    doc.Save(@"Test064\out.doc");
}

private void InsertImageFromURL(DocumentBuilder builder, string url, double width, double height)
{
    try
    {
        //Prepare the web page we will be asking for
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
        request.Method = "GET";
        request.ContentType = "image/JPEG";
        request.UserAgent = "Mozilla/4.0+(compatible;+MSIE+5.01;+Windows+NT+5.0";
        //Execute the request
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
        //We will read data via the response stream
        Stream resStream = response.GetResponseStream();
        //Write content into the MemoryStream
        BinaryReader resReader = new BinaryReader(resStream);
        MemoryStream imgStream = new MemoryStream(resReader.ReadBytes((int)response.ContentLength));
        //Insert image into the document
        builder.InsertImage(imgStream, width, height);
    }
    catch (WebException ex)
    {
        //Handle web exceptions
    }
    catch (Exception ex)
    {
        //Handle other exceptions
    }
}

You can parse ex.Status. Please see the following link for more information.

Hope this helps.

Best regards.

Thank you for the quick response and help. The problem was actually a flag set in VS 2005 to throw an error for all CLR exceptions. Turning the flag off thru Debug | Exceptions… allowed me to capture and handle exceptions in the ‘catch’.

Thank you again,
