Error reading in date using Zoo in R

- by SASnewby

I am trying to use the Zoo package to read in daily observations which do not occur on each day. The date format looks like this, and it is in the first column of dataset: 25-May-07 The command I use is: z <- read.zoo("multiplier7.csv", sep = ";", header = TRUE, format="%d-%b-%y") I get this error: Error in strptime(x, format, tz = "GMT") : input string is too long First question is: 1. Is Zoo the right package to use if I want to use lm regression with a spline time dummy? The bs command does not work because I need to convert it into a time series. 2. Why is this error occurring and how to fix?

Reading a plist utf-8 value as utf-16

- by ennuikiller

I'm working on an iphone app that needs to display superscripts and subscripts. I'm using a picker to read in data from a plist but the unicode values aren't being displayed corretly in the pickerview. Subscripts and superscripts are not being recognized. I'm assuming this is due to the encoding of the plist as utf-8, so the question is how do a convert a plist string encoding from utf-8 to utf-16 ? Just a little more elaboration: If I do this it displays properly at least in a textfield: NSString *equation = @"x\u00B2 + y\u00B2 = z\u00B2" However if I define the same string in a plist and try to read it in and assign it to a string and display it on a pickerview it just displays the the encoding and not the superscripts. @Matt: thanks for your suggestion the unicode is being escaped that is \u00B2 = \u00B2. Googling for "escaped values in plists" returned no useful results, and I haven't been able to use the keyboard cmd-ctrl-shift-+ to work. Any further suggestions would be greatly appreciated!!

Reading text out of textbox in Radgrid

- by Christophe

I have a Radgrid with 2 Textboxes and 2 DatePickers. The idea is that I have a grid with a Property name, value, valid from and until. I'm filling the first Textbox myself, the user has to fill in the value, from and until. Filling in the propertynames: (In the pageload) foreach (String s in testProperties) { DataRow dr = dt.NewRow(); dr[0] = s; dr[1] = ""; dr[2] = ""; dr[3] = ""; dt.Rows.Add(dr); } When the user hit "Save" I have to read out all the data he filled in. (In the btnSave click) foreach (GridDataItem dataItem in RadGrid1.Items) { String[] str = new String[3]; str[0] = ((TextBox)dataItem["col2"].FindControl("TextBox2")).Text; str[1] = ((RadDatePicker)dataItem["col3"].FindControl("RadDatePicker1")).SelectedDate.ToString(); str[2] = ((RadDatePicker)dataItem["col4"].FindControl("RadDatePicker2")).SelectedDate.ToString(); properties.Add(((TextBox)dataItem["col1"].FindControl("TextBox1")).Text, str); } Now this is where I have the problem. When i read out the data all my 'str' have the value "" instead the data that the user fills in. Question is, how comes my values in the texboxes remain ""? Or is their a better way to read out the data?

[C#] Is variable assignment and reading atomic operation (threading)

- by AStrangerGuy

I was unable to find any reference to this in the documentations... Is assigning to a double (or any other simple type, including boolean) an atomic operation viewed from the perspective of threads? double value = 0; public void First() { while(true) { value = (new Random()).NextDouble(); } } public void Second() { while(true) { Console.WriteLine(value); } } In this code sample, first method is called in one thread, and the second in another. Can the second method get a messed up value if it gets its execution during assignment to the variable in another thread? I don't care if I recieve the old value, it's only important to receive a valid value (not one where 2 out of 8 bytes are set). I know it's a stupid question, but I want to be sure, cause I don't know how CLR actually sets the variables. Thanks

Reading status from Zebra Printer

- by pmoreira

Hi, I'm working on a project where we need to use a Zebra Printer for barcode labels. We're using C#, and we're doing OK on the printing side of things, sending raw ZPL strings to the printer (using winspool.drv). However, we also need to read from the printer, and no luck there. We need to get the status from the printer, which is the output to the ZPL command "~HS", so we can tell how many labels are in memory waiting to be printed. The EnumJobs() from winspool.drv only has jobs on the windows spool, and once they're sent to the printer, they're gone from that list. But that doesn't mean the label has been printed, since the printer has a peel sensor and only prints one label at a time, and we're obviously interested in sending batches of labels to the printer. I've tried something like (using the winspool.drv calls): OpenPrinter(szPrinterName, out hPrinter, IntPtr.Zero); WritePrinter(hPrinter, pBytes, dwCount, out dwWritten); // send the string "~HS" ReadPrinter(hPrinter, data, buff, out pcRead); But I get nothing on the ReadPrinter call. I don't even know if this is the right way of going at it. Anyone out there tackled this before? Thanks.

Lots of questions about file I/O (reading/writing message strings)

- by Nazgulled

Hi, For this university project I'm doing (for which I've made a couple of posts in the past), which is some sort of social network, it's required the ability for the users to exchange messages. At first, I designed my data structures to hold ALL messages in a linked list, limiting the message size to 256 chars. However, I think my instructors will prefer if I save the messages on disk and read them only when I need them. Of course, they won't say what they prefer, I need to make a choice and justify the best I can why I went that route. One thing to keep in mind is that I only need to save the latest 20 messages from each user, no more. Right now I have an Hash Table that will act as inbox, this will be inside the user profile. This Hash Table will be indexed by name (the user that sent the message). The value for each element will be a data structure holding an array of size_t with 20 elements (20 messages like I said above). The idea is to keep track of the disk file offsets and bytes written. Then, when I need to read a message, I just need to use fseek() and read the necessary bytes. I think this could work nicely... I could use just one single file to hold all messages from all users in the network. I'm saying one single file because a colleague asked an instructor about saving the messages from each user independently which he replied that it might not be the best approach cause the file system has it's limits. That's why I'm thinking of going the single file route. However, this presents a problem... Since I only need to save the latest 20 messages, I need to discard the older ones when I reach this limit. I have no idea how to do this... All I know is about fread() and fwrite() to read/write bytes from/to files. How can I go to a file offset and say "hey, delete the following X bytes"? Even if I could do that, there's another problem... All offsets below that one will be completely different and I would have to process all users mailboxes to fix the problem. Which would be a pain... So, any suggestions to solve my problems? What do you suggest?

Reading audio with Extended Audio File Services (ExtAudioFileRead)

- by Paperflyer

I am working on understanding Core Audio, or rather: Extended Audio File Services Here, I want to use ExtAudioFileRead() to read some audio data from a file. This works fine as long as I use one single huge buffer to store my audio data (that is, one AudioBuffer). As soon as I use more than one AudioBuffer, ExtAudioFileRead() returns the error code -50 ("error in parameter list"). As far as I can figure out, this means that one of the arguments of ExtAudioFileRead() is wrong. Probably the audioBufferList. I can not use one huge buffer because then, dataByteSize would overflow its UInt32-integer range with huge files. Here is the code to create the audioBufferList: AudioBufferList *audioBufferList; audioBufferList = malloc(sizeof(AudioBufferList) + (numBuffers-1)*sizeof(AudioBuffer)); audioBufferList->mNumberBuffers = numBuffers; for (int bufferIdx = 0; bufferIdx<numBuffers; bufferIdx++ ) { audioBufferList->mBuffers[bufferIdx].mNumberChannels = numChannels; audioBufferList->mBuffers[bufferIdx].mDataByteSize = dataByteSize; audioBufferList->mBuffers[bufferIdx].mData = malloc(dataByteSize); } UInt32 numFrames = fileLengthInFrames; error = ExtAudioFileRead(extAudioFileRef, &numFrames, audioBufferList); Do you know what I am doing wrong here?

jQuery ajax doesn't seem to be reading HTML data in Chromium

Reading binary data from serial port using Dejan TComport Delphi component

- by johnma

Apologies for this question but I am a bit of a noob with Delphi. I am using Dejan TComport component to get data from a serial port. A box of equipment connected to the port sends about 100 bytes of binary data to the serial port. What I want to do is extract the bytes as numerical values into an array so that I can perform calculations on them. TComport has a method Read(buffer,Count) which reads DATA from input buffer. function Read(var Buffer; Count: Integer): Integer; The help says the Buffer variable must be large enough to hold Count bytes but does not provide any example of how to use this function. I can see that the Count variable holds the number of bytes received but I can't find a way to access the bytes in Buffer. TComport also has a methord Readstr which reads data from input buffer into a STRING variable. function ReadStr(var Str: String; Count: Integer): Integer; Again the Count variable shows the number of bytes received and I can use Memo1.Text:=str to display some information but obviously Memo1 has problems displaying the control characters. I have tried various ways to try and extract the byte data from Str but so far without success. I am sure it must be easy. Here's hoping.

The request is made with the DefaultHttpClient, but this is supposedly thread safe. What am I missing? If anything needs to be clarified just ask :) Cheers, Emil H

Can someone provide an example of seeking, reading, and writing a >4GB file using boost iostreams

I have read that boost iostreams supposedly supports 64 bit access to large files semi-portable way. Their FAQ mentions 64 bit offset functions, but there is no examples on how to use them. Has anyone used this library for handling large files? A simple example of opening two files, seeking to their middles, and copying one to the other would be very helpful. Thanks.

C# Multithreading File IO (Reading)

- by washtik

We have a situation where our application needs to process a series of files and rather than perform this function synchronously, we would like to employ multi-threading to have the workload split amongst different threads. Each item of work is: 1. Open a file for read only 2. Process the data in the file 3. Write the processed data to a Dictionary We would like to perform each file's work on a new thread? Is this possible and should be we better to use the ThreadPool or spawn new threads keeping in mind that each item of "work" only takes 30ms however its possible that hundreds of files will need to be processed. Any ideas to make this more efficient is appreciated.

Reading a WAV file into VST.Net to process with a plugin

- by Paul

Hello, I'm trying to use the VST.Net and NAudio frameworks to build an application that processes audio using a VST plugin. Ideally, the application should load a wav or mp3 file, process it with the VST, and then write a new file. I have done some poking around with the VST.Net library and was able to compile and run the samples (specifically the VST Host one). What I have not figured out is how to load an audio file into the program and have it write a new file back out. I'd like to be able to configure the properties for the VST plugin via C#, and be able to process the audio with 2 or more consecutive VSTs. Using NAudio, I was able to create this simple script to copy an audio file. Now I just need to get the output from the WaveFileReader into the VST.Net framework somehow. private void processAudio() { reader = new WaveFileReader("c:/bass.wav"); writer = new WaveFileWriter("c:/bass-copy.wav", reader.WaveFormat); int read; while ((read = reader.Read(buffer, 0, buffer.Length)) > 0) { writer.WriteData(buffer, 0, read); } textBox1.Text = "done"; reader.Close(); reader.Dispose(); writer.Close(); writer.Dispose(); } Please help!! Thanks References: http://vstnet.codeplex.com (VST.Net) http://naudio.codeplex.com (NAudio)
