I'm currently trying to send an image through JDA but can't get it to work. The only thing I can find on Google is the addFile (java.io.File) method, which is no longer available in the most recent version of JDA. I am currently struggling to find a solution using the addFiles() method.
This is my current attempt.
byte[] buffer = ((DataBufferByte)(img).getRaster().getDataBuffer()).getData();
FileUpload upload = new FileUpload(new ByteArrayInputStream(buffer));
c.sendMessage("Image:").addFiles(upload).complete();
I am getting this error message in my IDE, but I don't know what to make of it.
thanks guys.
You have to use the factory method FileUpload.fromData:
FileUpload upload = FileUpload.fromData(buffer, "image.png");
Make sure you properly encode the image to something like JPG or PNG, otherwise this will not work.

iam new here and hope someone can help me out.
iam trying to convert a html string to a pdf version in net5. We had it running in net core 2.2 without any problems. Now we are trying to migrate everything to net5. Well the only part which is not working anymore is converting html string to pdf document.
We are using following nuget package: Select.HtmlToPdf.NetCore
As soon we try the convert the html string with "ConvertHtmlString" we get following Exception.
System.ArgumentNullException: 'Value cannot be null. Arg_ParamName_Name'
here is a simple snippet to repdoruce the problem:
var htmlString = "<html><head></head><body>Test me out!</body></html>";
var converter = new HtmlToPdf();
converter.Options.PdfPageSize = PdfPageSize.Letter;
converter.Options.AutoFitWidth = HtmlToPdfPageFitMode.AutoFit;
converter.Options.AutoFitHeight = HtmlToPdfPageFitMode.AutoFit;
converter.Options.PdfPageOrientation = PdfPageOrientation.Landscape;
SelectPdf.PdfDocument doc = converter.ConvertHtmlString(htmlString);
doc.Save("C:\\Temp\\test.pdf");
doc.Close();
Thanks.

Ok thx for the hint in the comment..
before i posted my question i did some standard stuff i always do before researching deeper..
Clean solution, restarted VisualStudio and so on.. nothing worked.
Ive checked my nuget packages and i had the correct one installed.
I removed the package and reinstalled it again and well it works now. Cant exactly say what the problem was but.. it works now.
I am using laravel-snappy to generate pdfs and show them in the browser. I am getting a blank page in return.The code I am using is this.
return PDF::loadView('emails.flightInvoice', $data)->inline();
I used the below code to save the PDF and it is working.
PDF::loadView('emails.flightInvoice', $data')->save('invoice.pdf');
can anyone please help me with this?
The inline() method requires a filename
Try
return PDF::loadView('pdf.invoice', $data)->inline('filename.pdf');
My app uses Google API client library for .NET to send emails with attachments.
When using Send(), I'm facing some limitations when it comes to file size of the attachments. So, I guess switching to Resumable upload as upload method may help. But it's pretty much undocumented.
Looking into source code, I guess using different Send() overload may be the way forward, but I can't figure out how to use it properly.
So, instead of attaching the files into message and calling it like this:
var gmailResult = gmail.Users.Messages.Send(new Message
{
Raw = base64UrlEncodedMessage
}, "me").Execute();
I should not attach the files to message and do something like following?
var gmailResult = gmail.Users.Messages.Send(new Message
{
Raw = base64UrlEncodedMessage
}, "me", fileStream, contentType).Upload();
The second version does not return any API error, but does nothing. I'm obviously missing something here.
How do I attach more than one attachment?
This is kind of an old question, but putting an answer here just in case anyone else needs it:
I was able to achieve this by converting my mime message into a stream (attachment(s) included), and then calling this overload on Send:
UsersResource.MessagesResource.SendMediaUpload googleSendRequest = service.Users.Messages.Send(null, "youremail#gmail.com", mimeMessageStream, "message/rfc822");
IUploadProgress created = googleSendRequest.Upload();
This will upload all of the attachments with the email message content and then send it off. I was able to send two 5 megabyte attachments in an email. Previously I was not able to send even one of those via the other Send method that takes in a base64 encoded mime message.
I want to get thumbnail of a video file which uri or path is given. I have searched for api in windows phone developer site bt with no success. If anybody have does this please help me.
There is a method GetThumbnailAsync in class StorageFile which intended to retrieve thumbnail of image and video files. So despite the fact that MSDN states that this method throws exception and not supported for Windows Phone 8, actually this method works when invoked with parameter ThumbnailMode = ListView. But I seems that using this method requires ID_CAP_MEDIALIB_PHOTO_FULL.
var files = await KnownFolders.CameraRoll.GetFilesAsync(); // Throw UnauthorizedAccessException without ID_CAP_MEDIALIB_PHOTO_FULL
var storageFile = files.First();
var thumbnail = await storageFile.GetThumbnailAsync(ThumbnailMode.ListView);
Video Thumbnail code in c# windows phone
First we use capturesource.completed then after we create the thumbnail and use that thumbnail
and we use capturesource.Imageasync()
And this is the only way to generate the thumbnail image from video file.
I'm developing an app for Windows Phone 7 and I'm using a Phonegap template for it.
Everything looks perfect, but now I’m stuck trying to open a PDF file in the browser.
I tried the following but that doesn’t work because the url of the PDF exceeds the 2048 character limit (it’s a data url). This code runs after the deviceReady event was fired.
var ref = window.open('http://www.google.com', '_blank', 'location=no');
ref.addEventListener('loadstart', function () { alert(event.url); });
Now, I'm trying to save the PDF file to storage and then I'm trying to have it opened by the browser, but the browser doesn't show anything. I'm editing the InAppBrowser.cs code from cordovalib and I added the following lines before calling browser.Navigate(loc);
private void ShowInAppBrowser(string url)
{
IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForApplication();
FileStream stream = store.OpenFile("test.pdf", FileMode.Create);
BinaryWriter writer = new BinaryWriter(stream);
var myvar = Base64Decode("the big data url");
writer.Write(myvar);
writer.Close();
if (store.FileExists("test.pdf")) // Check if file exists
{
Uri loc = new Uri("test.pdf", UriKind.Relative);
...
}
}
This code is returning the following error:
Log:"Error in error callback: InAppBrowser1921408518 = TypeError: Unable to get value of the property 'url': object is null or undefined"
I don’t wanna use ComponentOne.
Any help would be greatly appreciated!
You cannot open pdf files from the isolated storage in the default reader for PDF files. If the file is online e.g. it has a URI for it, you can use WebBrowserTask to open it since that will download and open the file in Adobe Reader.
On Windows Phone 8 you actually can open your own file in default file reader for that extension, but I am not sure how that will help you since you target PhoneGap and Windows Phone 7.
Toni is correct. You could go and try to build your own viewer (which would be the same thing as using C1, but with more time involved). I worked on a port of iTextSharp and PDFSharp for WP7, but neither of which are PDF Viewers. They are good for creating PDFs and parsing them some (but to render them there is more work involved). This has been a personal quest of mine, but honestly the best I have gotten is to be able to extract some images from the PDF (and none of the text)
try this
var installedLocation = Windows.ApplicationModel.Package.Current.InstalledLocation;
var assets = await installedLocation.GetFolderAsync("Assets");
var pdf = await assets.GetFileAsync("metro.pdf");
Windows.System.Launcher.LaunchFileAsync(pdf);
This worked correctly on my Device.
