To use this fun c tion simply provide file path to external file. This fun c tion uses System. Modify the ex c eption handling se c tion to as your proje c t requirements. The obje c t is a dynami c ally c reated Ex c el workbook. As per my understanding an obje c t c an be written and read from a stream Only if it's serialized. Here is c ode What i must supposed to do to read ex c el file from byte array without saving it?
Any idea? Fuat Tatar responded If you want to add a new line while using the VBA MsgBox you c an use any of the above three c onstants that we have dis c ussed.. ReadAllBytes String is an inbuilt File class method that is used to open a specified or created binary file and then reads the contents of the file into a byte array and then closes the file.
If I didn't make it clear, let me know. The My. FileSystem object provides the ReadAllBytes method for reading from binary files. To read from a binary file Use the ReadAllBytes method, which returns the contents of a file as a byte array. Converting excel byte array data into datatable C API How to convert an excel file into byte array and perform Using c to read Excel workbook data into an array, and ReadByte Method System.
The original file from the client is sent via TCP and then received by a server. The received stream is read to a byte array and then sent to be processed by this class. This is mainly to ensure that the receiving TCPClient is ready for the next stream and separate the receiving end from the processing end.
The FileStream class does not take a byte array as an argument or another Stream object which does allow you to write bytes to it. I'm aiming to get the processing done by a different thread from the original the one with the TCPClient. Based on the first sentence of the question: "I'm trying to write out a Byte[] array representing a complete file to a file. Edit: Oops, forgot the finally part You can use the FileStream.

Todd Moses Todd Moses What's the point of using a BufferedStream when you're reading the whole thing at once? He asked for the best performance not to read the file at once. Performance is measurable in the context of an operation. Additional buffering for a stream that you're reading sequentially, all at once, to memory is not likely to benefit from an extra buffer.
