I am managing to send mails just fine with send grid, attachment too no issues. But I am having problems embedding images into the body of the HTML mail
Here is the code that I am using, put together after reading various examples on this issue. Anyone know where I am going wrong, regards...
MemoryStream msLogo = new MemoryStream(obj.logo);
Bitmap b = new Bitmap(msLogo);
ImageConverter ic = new ImageConverter();
Byte[] ba = (Byte[])ic.ConvertTo(b, typeof(Byte[]));
MemoryStream logo = new MemoryStream(ba);
AlternateView htmlView = AlternateView.CreateAlternateViewFromString(sBody, null, "text/html");
LinkedResource imageResource = new LinkedResource(logo);
var imagelink = new LinkedResource(logo, "image/png");
imagelink.ContentId = string.Format("logo", myMessage);
imagelink.TransferEncoding = TransferEncoding.Base64;
b.Save(logo, ImageFormat.Jpeg);
logo.Position = 0;

I am using Mvc.Net API with open XML. I need to replace multiple images in .docx file.I replace the images in current scenario but I don't get any Id or Name of the Image at my code side so facing difficulties to replace those images.
Here is my code
List<ImagePart> imgPartList = doc.MainDocumentPart.ImageParts.ToList();
foreach(ImagePart imgPart in imgPartList)
{
string Id=doc.MainDocumentPart.GetIdOfPart(imgPart);
byte[] imageBytes = File.ReadAllBytes(ImagePath);
BinaryWriter writer = new BinaryWriter(imgPart.GetStream());
writer.Write(imageBytes);
writer.Close();
}
Can I get the name of Image in ImagePart?
I would do something like this:
List<ImagePart> imgPartList = doc.MainDocumentPart.ImageParts.ToList();
foreach(ImagePart imgPart in imgPartList)
{
var imageId = document.MainDocumentPart.GetIdOfPart(imgPart.Id);
byte[] imageBytes = File.ReadAllBytes(ImagePath);
BinaryWriter writer = new BinaryWriter(imgPart.GetStream());
writer.Write(imageBytes);
writer.Close();
}

I am trying to do this on ASP.NET MVC 4:
MemoryStream mem = new MemoryStream();
using (WordprocessingDocument wordDoc =
WordprocessingDocument.Create(mem, DocumentFormat.OpenXml.WordprocessingDocumentType.Document, true))
{
// instantiate the members of the hierarchy
Document doc = new Document();
Body body = new Body();
Paragraph para = new Paragraph();
Run run = new Run();
Text text = new Text() { Text = "The OpenXML SDK rocks!" };
// put the hierarchy together
run.Append(text);
para.Append(run);
body.Append(para);
doc.Append(body);
//wordDoc.Close();
///wordDoc.Save();
}
return File(mem.ToArray(), "application/vnd.openxmlformats-officedocument.wordprocessingml.document", "ABC.docx");
However the ABC.docx opens as corrupted and it wouldn't open even after fixing it.
Any ideas?
Linked Qs:
Streaming In Memory Word Document using OpenXML SDK w/ASP.NET results in "corrupt" document
Apparently the problem comes from missing this 2 lines:
wordDoc.AddMainDocumentPart();
wordDoc.MainDocumentPart.Document = doc;
Updated the code to below and it now works flawlessly, even without any extra flushing, etc necessary.
MemoryStream mem = new MemoryStream();
using (WordprocessingDocument wordDoc =
WordprocessingDocument.Create(mem, DocumentFormat.OpenXml.WordprocessingDocumentType.Document, true))
{
wordDoc.AddMainDocumentPart();
// instantiate the members of the hierarchy
Document doc = new Document();
Body body = new Body();
Paragraph para = new Paragraph();
Run run = new Run();
Text text = new Text() { Text = "The OpenXML SDK rocks!" };
// put the hierarchy together
run.Append(text);
para.Append(run);
body.Append(para);
doc.Append(body);
wordDoc.MainDocumentPart.Document = doc;
wordDoc.Close();
}
return File(mem.ToArray(), "application/vnd.openxmlformats-officedocument.wordprocessingml.document", "ABC.docx");
For public link it works fine, but in my case I need upload a image file from local disk. I converted the image into base64 format, and write the html file into local disk as well, that html file can be opened in browser with image showing, but the document in google doc just an empty file, even I drag that html file into google docs the image still not there. My code is below:
DocsService client = new DocsService("testappv3");
client.setUserCredentials("username", "password");
File file = new File("c:/test.bmp");
ByteArrayOutputStream out = new ByteArrayOutputStream();
BufferedInputStream in = new BufferedInputStream(new FileInputStream(file));
int read;
byte[] buff = new byte[1024];
while ((read = in.read(buff)) > 0)
{
out.write(buff, 0, read);
}
out.flush();
String base64 = Base64.encode(out.toByteArray());
String mimeType = DocumentListEntry.MediaType.fromFileName(file.getName()).getMimeType();
String html = "<html><body><img src=\"data:" + mimeType + ";base64," + base64 + "\"/></body></html>";
URL destFolderUrl = new URL("https://docs.google.com/feeds/default/private/full/<FOLDER_ID>/contents");
DocumentEntry newDocument = new DocumentEntry();
newDocument.setTitle(new PlainTextConstruct("test"));
newDocument.setMediaSource(new MediaByteArraySource(html.getBytes(), "text/html"));
newDocument = client.insert(destFolderUrl, newDocument);
Look my experience level is only a few years so I could well be wrong but .... My understanding is that you can no longer use
client.insert(destFolderUrl, newDocument);// but now must use ResumableGDataFileUploader
new ResumableGDataFileUploader.Builder(client, new URL(uploadLink), mediaFile, null )
hopefully someone with more knowledge will confirm or deny

This looks like a bug, we are trying to fix it, and I will get back to you when we have a fix.
Thanks for your patience.
I have some files in IsolatedStorage in my application. The file types are different, say doc,xls,ppt,pdf,mp3,mov,jpg,png etc.. I need to open these files. How can I do this.
Try to open it with name and its extensions
byte[] data;
using (IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication())
{
using (IsolatedStorageFileStream isfs = isf.OpenFile(image.jpg, FileMode.Open, FileAccess.Read))
{
data = new byte[isfs.Length];
isfs.Read(data, 0, data.Length);
isfs.Close();
}
}
MemoryStream ms = new MemoryStream(data);
BitmapImage bi = new BitmapImage();
bi.SetSource(ms);
Image img = new image();
img.source = bi
if it is an image try to set the source of a bitmap image as memory stream ms.
