"Concatenate int and byte",
"First, I am very new to c#, so please, bear with me. I am trying to set 3 ints and 4 bytes to a computer via UDP. I've used this thread to help with concatenating my variables Best way to combine two or more byte arrays in C#. Currently, I am having an error trying to BlockCopy the bytes into an array. My array is 12 bytes long and I need bytes 9, 4, 5 and 6. My code is \n\nbyte[] UDPPacket = new byte[16];\nBuffer.BlockCopy(button[9],0,UDPPacket,0,1);\n\n\nand it is erroring with\n\n(parameter)byte[]buttons\n\n\nI believe the BlockCopy method works for a bytewise copy of one array to the other. Any insight into what I'm doing wrong?"

"Create a List of objects with for nicely",
"I was wondering what is the nicest way to create a List of objects.\n\nWhat I was able to come up with is either converting the used Range to List:\n\nval objs: List[String] =\n for (i <- 1.to(100).toList)\n yield new String(\"\" + i)\n\n\nor to convert the whole result wit toList:\n\nval objs: List[String] =\n (for (i <- 1 to 100 )\n yield new String(\"\" + i)).toList\n\n\nBut none of them looks smooth enough for me. Is there any easier way to do this? The variable must be of type List because it is used elsewhere in the code I'm playing with. Thanks in advance!"

"How to update timestamp column moving date forward",
"what I am looking for is some help with a query.\n\nI have a MySql field with unixtime in it representing a date in each of the next few dozen months. I have to move the dates forward to the first day of the next month for each entry in the table.\n\nThe dates are all the 20th of each month, and so I want to move June 20 to July 1, July 20 to August 1, and so on. I can't just add 11 days, because that wouldn't be the first day of the next month when considering months with 31 days and February.\n\nI have been playing with ideas like this:\n\nupdate table set column = UNIX_TIMESTAMP(column + MONTH(column)+1,DAY(1)) where index_column = '1234'\n\n\nbut I am pretty sure that won't work. I could use something like this to convert it, then try to convert it back:\n\nupdate table set column = DATEFORMAT(column,'%Y-$c-%d %H:%i:%s') where index_column == '1234'\n\n\nI still think there has to be a better way. Frankly, I would update the few dozen manually, but I know this will come up frequently, and don't want to have to do it manually every time. \n\nI prefer not to use code, but would instead like to just do it directly into MySql. I hope there is someone out there that can help me figure this out.\n\nThank you in advance."

"How to scroll PyGTK ScrolledWindow to a certain row of a nested table?",
"I have a program in PyGTK which has a ScrolledWindow and a Table nested in it. The table rows can be of a different height. What I'm trying to find is a way to scroll the view so it begins from the selected row. I know how to move the scrollbar to a certain position using the scrolled_window.get_vadjustment().set_value(), but I do not know how to find the scroll position of the table rows.\n\nAlternatively, maybe I'm using wrong widget and someone can point me to the right one? I'm trying to achieve the following behaviour: the screen shows the rows of a table, the top row is the currently selected object, when the user presses up or down buttons, the whole table scrolls down or up, so the previous or the next row becomes the top row."

"Live Audio Streaming from Webpage",
"I am working on a Swing radio project in which the user types in a URL, and my Java Program will take live audio from the given link and play it live for the user. The issue is that the user may type in a live radio URL that may not be formatted as an .mp3/.wav/.aiff file, it could just be a website-link that plays audio when launched through an online media player, such as in BBC Radio One (http://www.bbc.co.uk/radio/player/bbc_radio_one). \n\nI have tried the Java Sound API, however, it only supports URLs that are directed to music files (ex. foo.com/bar.wav/). The sound API cannot support URLs such as http://www.bbc.co.uk/radio/player/bbc_radio_one because they are not audio files. If you were to go to the BBC Radio One link, you would find that it automatically starts playing live audio. That live audio is what I'd like to have played in my Java program. \n\nOn StackOverflow, I had found people who had similar issues to mine, but they were using .mp3/.wav/.aiff/ etc URLs, which is good, but does not work for me.\n\nI had also found a page on Program Creek that had shown multiple methods of playing audio through URLs. I had tried to use many of the examples on there, but none of them would work because of either the format of my URL or Stream Errors. For instance, I had slightly modified one of the methods (from example 4 on Program Creek):\n\n /**\n * Plays the audio file specified in the 'url' parameter.\n * @param url URL for Audio Loading\n */\npublic void play(final String url) {\n try {\n InputStream in = getClass().getResourceAsStream(url);\n InputStream buf = new BufferedInputStream(in);\n AudioInputStream ain = AudioSystem.getAudioInputStream(buf);\n AudioFormat format = ain.getFormat();\n DataLine.Info info = new DataLine.Info(Clip.class, format);\n Clip clip = (Clip) AudioSystem.getLine(info);\n clip.open(ain);\n clip.start();\n } catch (Exception e) {\n e.printStackTrace();\n }\n}\n\n\nAnd I'd get the following error (here) when I'd give the BBC Radio One URL (http://www.bbc.co.uk/radio/player/bbc_radio_one) for it to play.\n\nIs there any way I could either get rid of this IOException error, or use a non-audio-file URL to receive a live audio stream a different way? Would you be able to lead me into the right path to figuring this out?\n\nThanks."

Whatever change made in the parent table will reflect in the child table. For example, if previous one row in the parent table is harry True Happy is changed to Harry True Sad, the child tables will also be changed . Also if a record in the parent table is deleted, the corresponding rows in the child tables will also be deleted. A new record in the parent table is created, the child table will also generate one row of record reflecting the update. \n\nI think the one-to-one relationship in Access will be a good way to achieve that.

"Python list comprehension: return value matching multiple if statements, else return other value",
"I'm working on list comprehension in python, and am having difficulty condensing my code into a single list comprehension statement.\n\nI'm writing a function to search a list of movie dictionaries that looks like this:\n\n movies = [\n {\n \"name\": \"Usual Suspects\", \n \"imdb\": 7.0,\n \"category\": \"Thriller\"\n },\n {\n \"name\": \"Hitman\",\n \"imdb\": 6.3,\n \"category\": \"Action\"\n },\n {\n \"name\": \"Dark Knight\",\n \"imdb\": 9.0,\n \"category\": \"Adventure\"\n }\n ]\n\n\nI'm trying to write a function that takes in an input of a movie name, checks the imdb score, and returns True if the score > 5.5, but returns false if the score doesn't meet this criteria. \n\nWriting in traditional code, I accomplished this like the following:\n\n def good_movie(movie_name):\n for m in movies: #for each item in movies...\n if m[\"name\"] == movie_name: #see if movie_name == \"name\", if it does...\n if m[\"imdb\"] > 5.5: # See if the movie's score is greater than 5.5...\n return \"True\" # If it is, return \"true\"\n else: #otherwise\n return \"False\" #return false\n\n\nI've been able to write this in list comprehension to return true, but can't get the function to work if I also want to return false when the movie doesn't meet the proper score criteria.\n\nThe short version that works is:\n\n def good_movie(movie_name):\n return [\"True\" for m in movies if m[\"name\"] == movie_name if m[\"imdb\"] > 5.5]\n\n\nHowever, I'd like to be able to return a value of False if the movie_name doesn't meet both of the if statements listed here. I've tried it a few different ways, but can't figure out how to make it work. \n\nSomething like this DOESN'T work:\n\n def good_movie(movie_name):\n return [\"True\" if m[\"imdb\"] > 5.5 and if m[\"name\"] == movie_name else \"False\" for m in movies]\n\n\nI thought maybe adding the \"and\" between the if statements would help (otherwise, it would think of the if statements as independent, rather than connected). \n\nI've worked with this back and forth a number of times, but any assistance anyone could provide would help me better understand how these sorts of list comprehensions work in the future.\n\nThanks for your help!\n\nEDIT: Thanks everyone for your replies. This was my first post on stack overflow, and I'm already blown away by the amount of response I've gotten for my small request. I understand that list comprehension is not the best way to address this problem in a real-world application, I am just in the process of learning list comprehension, and wanted to see how I could solve this problem in normal python, without importing pandas, etc. Thank you again to everyone who contributed!"

Also every time an element from the input string is consumed, the DFA only provides if the current state is success or not.\n\nfor (int i = 0; i < input.length; i++) {\n int _index = this.events.indexOf((char) input[i]);\n\n if (_index == -1) {\n for (int j = 0; j < this.events.length(); j++) {\n for (int k = 0; k < this.events.length(); k++) {\n dfaMatrix[j][k].startTraversal(input[i]);\n dfaMatrix[k][j].startTraversal(input[i]);\n }\n }\n } \n else {\n for (int j = 0; j < this.events.length(); j++) {\n dfaMatrix[_index][j].startTraversal(input[i]);\n dfaMatrix[j][_index].startTraversal(input[i]);\n\n if (dfaMatrix[_index][j].isSuccess()) {\n count[_index][j] += 1;\n flag = true;\n break;\n } else if (dfaMatrix[j][_index].isSuccess()) {\n count[j][_index] += 1;\n flag = true;\n break;\n }\n }\n if (flag) {\n for (int k = 0; k < this.events.length(); k++) {\n for (int m = 0; m < this.events.length(); m++) {\n dfaMatrix[k][m].reinitialize();\n dfaMatrix[m][k].reinitialize();\n }\n }\n flag = false;\n for (int j = 0; j < this.events.length(); j++) {\n dfaMatrix[_index][j].startTraversal(dfaMatrix[_index][j].getDfat(), input[i]);\n dfaMatrix[j][_index].startTraversal(dfaMatrix[j][_index].getDfat(), input[i]);\n }\n }\n }\n }\n\n\nMy expected results are:\n\n[A][A] : 1\n[A][B] : 0\n[A][C] : 0\n[B][A] : 0\n[B][B] : 0\n[B][C] : 0\n[C][A] : 2\n[C][B] : 0\n[C][C] : 0\n\n\nBut I'm getting\n\n[A][A] : 2\n[A][B] : 0\n[A][C] : 0\n[B][A] : 0\n[B][B] : 0\n[B][C] : 0\n[C][A] : 1\n[C][B] : 0\n[C][C] : 0\n\n\nFor some reason when the DFA is consuming the second C, the DFA is not reinitialising where logically it should be reaching error state. Can anyone tell me where I'm going wrong?"

"C# - Generalized SQL Server stored procedure calls",
"I'm trying something new (for me, at least) and, rather than having specific functions for calling individual stored procedures (1-to-1 ratio of data access functions to stored procedures), I'm trying to write generalized functions that are passed a stored procedure name, as well as string arrays of parameter names and parameter values as arguments.\n\nFor example:\n\npublic DataTable CallQuery(string spName, string[] paramNames, string[] paramValues, string connString)\n{\n DataTable dt = new DataTable();\n SqlConnection conn = new SqlConnection(connString);\n\n try\n {\n //create a command and assign it to the passed stored procedure name\n SqlCommand cmd = new SqlCommand();\n cmd.Connection = conn; // new SqlConnection(connString); ;\n cmd.CommandText = spName;\n\n //add any and all parameters to the command\n for(int i = 0; i < paramNames.Length; i++)\n {\n SqlParameter temp = new SqlParameter(paramNames[i], paramValues[i]);\n cmd.Parameters.Add(temp);\n //cmd.Parameters.AddWithValue(paramNames[i], paramValues[i]);\n }\n\n //get the data and return it\n SqlDataAdapter da = new SqlDataAdapter(cmd);\n da.Fill(dt);\n\n return dt;\n }\n catch (Exception)\n {\n return dt;\n }\n}\n\n\nUnfortunately, for some reason, when I call this function with parameter values (i.e. paramNames[0] = \"@Provider\" and paramValues[0] = \"AT&T\") and make the database call, I catch an exception saying that the stored procedure was expecting the parameter @Provider.\n\nI've stepped through and verified that the parameters are being added with their values, but I'm still getting the same exception. Am I missing something simple here?\n\nThe reason I'm passing in the string arrays is because there could be anywhere from 0 to 5 parameters per stored procedure (so far...)."
