View 14 RepliesI'm getting the following error when decoding a creation date:A first chance exception of type 'System.ArgumentOutOfRangeException'occurred in mscorlib.dll Hour, Minute, and Second parameters describe an un-representable DateTime.
I'm doing pdfdate.decode(xdoc.info("creationdate"))
Here's the info from the PDF file:
/CreationDate (D:191010319150120)
/Producer (Acrobat Distiller Daemon 3.01 for Solaris 2.3 and later
(SPARC))
/Creator (tif_convert_2_ps())
/Title (/tardir/tiffs/a386689.tiff)
/ModDate (D:20010320070957)
The Modification date seems to be a valid date, but, the creation date looks kinda weird to me. More intriguing is that when I get the properties of this file using ADOBE Reader it shows a valid date for the creation date field.

I am writing some rest calls to the LinkedIn API using web request and have hit an encoding issue.The LinkedIn API takes requires an encoded URI as one of the parameters on the lookup i am trying to run.
We are calling the api through .Net's WebRequest.Create; and when we pass in the URI it decodes it and as a result we can't get the data from the call. Im trying to open a URI like this[URL]..Is there a mechanism in the webrequest class to stop it decoding the passed in URI; or a work around for this?

2.Create a mp3 player by use of a decoder for playing this mp3 file.
I want some help from the best audio programmer who can explain me the decoding logic used to play the mp3 file(Programatically) I am aware of the bit patterns and the data chunks of mp3.I have the knowledge of the data chunks used in mp3 and wav files .I have also used winmm.dll file earlier to ascend into and descend out of the data chunks of wave files.But don't know how the bits are played in a player.Now I need to convert the wav file into mp3 format by use of some encoder program.I came to know about some lame encoder program but am unable to get how to start understanding it's code.

The error is Value of type '1-dimensional array of string' cannot be converted to 'String'.
I am trying to write a thread safe application that contains 3 threads : -
1 - Data acquisition and decoding
2- Data graphing
3 - FFT and filtering
Thread 1 is collecting bytes from the serial port and converting them int integers (so taking two bytes) after is has captured 64 Bytes and converted into 32 integers, it then needs to pass the array to the graphing thread.
The graphing thread then plots the data and waits for more data.
Thread 3 also waits until thread one has collected 2023 integers and takes these and performs some FFT calculations (which take time).
My question is how do i share the arrays between the three threads without deadlocking the program? as the serial thread will be flying around reasonable fast (1000 bytes per second) so it will synclock onto the shared buffers for most of the time.
Originally i was going to use two synchronised queues, so when thread 1 has collected 32 bytes it queues the data into the graph queue, and once it has collected 2023 it queues the data into the FFT queue.
Then thread 2 and 3 can simple dequeue the data.
However using queues has the overhead of casting the data in and out, and as i know the data type i was planning on using two arrays :-
Dim GraphArray() as ushort
Dim FFTArray() as ushort
Then Thread 1 adds data to each thread, and thread 2 and 3 simple wait until the correct amount of data is available before removing the data. my question is there an array type that allows me to remove x amount of data from an array?
Because i cannot do this easily with the ararys defined as above (GraphArray, FFTArray), as i was planning on making them 1mByte and allowing thread 1 to fill them Knowing they should never overflow and then let thread 2 and 3 remove x amout of bytes at a time unless there is a better way of doing it
So, imagine I have a RichTextBox control and a few buttons to allow the user to change the font size, set/unset bold, italic etc, and perhaps change the colour. Not much more than that. Can I then - in code - loop through the contents of the RichTextBox and determine which words are in bold or red or whatever, and where paragraphs start and end?
