JADE Environment Development Ideas

.Net Control built to allow drag and drop, the files + directory is now natively supported in Jade 2018 but the drag and drop email is not. See - // drag and drop from embedded attachment in email

// this event fires when the drop has occurred

private void DropTarget_DragDrop(object sender, DragEventArgs e)

{

// drag and drop from file system

if (e.Data.GetDataPresent(DataFormats.FileDrop))

{

// support multiple drag and drop from file system

string[] files = (string[])e.Data.GetData(DataFormats.FileDrop);

foreach (string file in files)

{

// call our internal OnDropEvent -> this will test if we have a Jade event handler assigned

OnDropEvent(file);

}

}

// drag and drop from embedded attachment in email

else if (e.Data.GetDataPresent("FileGroupDescriptor"))

{

Stream stream = (Stream)e.Data.GetData("FileGroupDescriptor");

// no nice api here that I could find.. very crude

// let's find the fileName

byte[] fileGroupDescriptor = new byte[512];

stream.Read(fileGroupDescriptor, 0, 512);

StringBuilder fileName = new StringBuilder("");

for (int i = 76; fileGroupDescriptor[i] != 0; i++)

{ fileName.Append(Convert.ToChar(fileGroupDescriptor[i])); }

string theFile = fileName.ToString();

// delete the file if it exists in your %temp% folder

FileInfo tempFile = new FileInfo(Path.Combine(Path.GetTempPath(), theFile));

if (File.Exists(tempFile.FullName))

{

tempFile.Delete();

}

// read the file contents into a memory stream and save it to disk

// e.g C:\Users\DurajM\AppData\Local\Temp\<fileName>

MemoryStream memoryStream = (MemoryStream)e.Data.GetData("FileContents", true);

Byte[] binary = new Byte[memoryStream.Length];

memoryStream.Position = 0;

memoryStream.Read(binary, 0, (int)memoryStream.Length);

FileStream fileStream = new FileStream(tempFile.FullName, FileMode.CreateNew);

fileStream.Write(binary, 0, (int)memoryStream.Length);

fileStream.Close();

// always good to make sure we actually created the file

if (File.Exists(tempFile.FullName))

{

// call our internal OnDropEvent -> this will test if we have a Jade event handler assigned

OnDropEvent(tempFile.FullName);

// delete the file from your %temp% folder

tempFile.Delete();

}

}
