LabVIEW Binary File from Database to .rtf in .Net control
I have one vi where I save a .rtf file to a database like so:
Later, I get the file from the database and save it as an .rtf before I open it with another vi (rtf viewer.vi):
However, Although rtf viewer.vi will work with files that are not uploaded to the database, it cannot read these files. Opening a file in Notepad++ gets me the following:
Ā萀ĀĀ ᄠĀ

The file does save, however, it's not able to be read by my viewer vi
Edit:
The issue is on the download side when writing to the binary file, I've been able to eliminate it by formatting the variant as a string before writing. However, that's added a '/00' char after every byte which I eliminate from the string after writing:
The Real problem here is that the LabVIEW string uploads to the Database as an array of I 32 values so each char is padded. As a result, we need to convert the string into a u8 array for the LabVIEW database upload vi to work correctly as such:
