Import images to document handling

I have managed to get to the point where I can get a stream created from my file from url. Having trouble figuring out how I can create the docuref and docuvalue table records from my stream. I have debugged the DocumentUpload form however the critical part of code is handled by the Uploadcontrol and I can't seem to get to the code that is actually sending the file to azure and getting back an id.

I have also looked at DocumentFileHelper::attachDocumentAsUser() however I'm having an issue with it wanting a string for documentcontents. Does anyone have an example of this being used to attach a jpeg?

Here is my code that generates the stream:

public void importFile()

{

System.IO.Stream newImage;

FileUploadTemporaryStorageResult result;

FileUploadTemporaryStorageStrategy strategy = new FileUploadTemporaryStorageStrategy();

//FileUploadTemporaryStorageResult result = File::GetFileFromUser() as FileUploadTemporaryStorageResult

//newImage = File::UseFileFromURL("C:\\Users\\axlocaladmin\\Downloads\\zhp710_P2.jpg");// as FileUploadTemporaryStorageResult;

newImage = File::UseFileFromURL("C:\\Users\\Public\\Documents\\zhp710_P21.jpg");

//result = strategy.uploadFile(newImage,"zhp710_P2","image/jpeg","jpg");

//File::SendFileToUser(newImage,"zhp710_P2","FileUploadTemporaryStorageStrategy");

}

You can see that I've played around with various options to no avail.

Thanks,

Don

You can use DocumentManagement.attachFile() (one of its arguments is a stream).

It looks like that will work. I was attemping to use DocumentFileHelper.attachDocumentAsUser() but DocumentManagement::AttachFile() appears to work and be easier to manage.

This method is working. I am able to get the proper DocuRef and DocuValue records created with this method using this line of code:

DocuRef = DocuManagement::AttachFile(tablenum(InventTable),22565437142,curExt(),'Image',newImage,'image.jpg','Image','image.jpg','image notes'); where "newImage" is the file stream. I am able to print the image on my report however.

My only issue is that the preview in Document management doesn't work. I am able to open the image so I assume it is stored properly. Thanks for the input. I will debug further tomorrow to try and discover why the preview doesn't work.

Hi Don Shields,

File::UseFileFromURL("C:\\Users\\Public\\Documents\\zhp710_P21.jpg"); works great with local files, but how are you going to use it in production environment ?

To attach image use next code

DocuRef docuRef = DocumentManagement::attachFile( inventTable.TableId, inventTable.RecId, curext(), DocuType::typeImage(), memoryStream, fileName, null, description); if (docuRef) { EcoResProductImage::create(docuRef); }

Yes that part of the code works. I am actually already using the EcoResProdcutImage::create and that works as well. As you said, File::UseFileFromURL("C:\\Users\\Public\\Documents\\zhp710_P21.jpg"); Works with the local drive. In production I will have to have an actual URL. I'm still working on that part.

I recently did similar modification and used Azure File storage for files, so users simply dumped files to file share and provide a spreadsheet where they mapped itemId to file path. It's quite easy to change code from File::UseFileFromURL to CloudFile.DownloadToStream, you can read about here

That looks like what I had in mind. I'm going to give it shot. I'll post back the results. Thanks!
