• What's the best way to access a MS Access database using PHP?

  - by Jack Roscoe

  Hi, I need to access some data from an MS Access database and retrieve some data from it using PHP. I've looked around the web, and found the following line which seems to correctly connect to the database: $conn->Open("DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=C:\wamp\www\data\MYDB.mdb"); However, I have tried to retrieve some data in the following way: $query = "SELECT pageid FROM pages_table"; $result = mysqli_query($conn, $query); $amount_of_pages = 0; if(mysqli_num_rows($result) <= 0) echo "No results found."; else while($row = mysqli_fetch_array($result, MYSQL_ASSOC)) $amount_of_pages++; And was presented with the following errors: Warning: mysqli_query() expects parameter 1 to be mysqli, object given in C:\wamp\www\data\index.php on line 19 Warning: mysqli_num_rows() expects parameter 1 to be mysqli_result, null given in C:\wamp\www\data\index.php on line 23 No results found. I don't really understand the connection to the Access database, is there something I should be doing differently? Thanks in advance for any help.

• python interactive mode module import issue

  - by Jeff

  I believe I have what would be called a scope issue, perhaps name space. Not too sure I'm new to python. I'm trying to make a module that will search through a list using regular expressions. I'm sure there is a better way of doing it but this error that I'm getting is bugging me and I want to understand why. here's my code: class relist(list): def __init__(self, l): list.__init__(self, l) def __getitem__(self, rexp): r = re.compile(rexp) res = filter(r.match, self) return res if __name__ == '__main__': import re listl = [x+y for x in 'test string' for y in 'another string for testing'] print(listl) test = relist(listl) print('----------------------------------') print(test['[s.]']) When I run this code through the command line it works the way I expect it to; however when I run it through python interactive mode I get the error >>> test['[s.]'] Traceback (most recent call last): File "<stdin>", line 1, in <module> File "relist.py", line 8, in __getitem__ r = re.compile(rexp) NameError: global name 're' is not defined While in the interactive mode I do import re and I am able to use the re functions, but for some reason when I'm trying to execute the module it doesn't work. Do I need to import re into the scope of the class? I wouldn't think so because doesn't python search through other scopes if it's not found in the current one? I appreciate your help, and if there is a better way of doing this search I would be interested in knowing. Thanks

• fastest way to check to see if a certain index in a linq statement is null

  - by tehdoommarine

  Basic Details I have a linq statement that grabs some records from a database and puts them in a System.Linq.Enumerable: var someRecords = someRepoAttachedToDatabase.Where(p=>true); Suppose this grabs tons (25k+) of records, and i need to perform operations on all of them. to speed things up, I have to decided to use paging and perform the operations needed in blocks of 100 instead of all of the records at the same time. The Question The line in question is the line where I count the number of records in the subset to see if we are on the last page; if the number of records in subset is less than the size of paging - then that means there are no more records left. What I would like to know is what is the fastest way to do this? Code in Question int pageSize = 100; bool moreData = true; int currentPage = 1; while (moreData) { var subsetOfRecords = someRecords.Skip((currentPage - 1) * pageSize).Take(pageSize); //this is also a System.Linq.Enumerable if (subsetOfRecords.Count() < pageSize){ moreData = false;} //line in question //do stuff to records in subset currentPage++; } Things I Have Considered subsetOfRecords.Count() < pageSize subsetOfRecords.ElementAt(pageSize - 1) == null (causes out of bounds exception - can catch exception and set moreData to false there) Converting subsetOfRecords to an array (converting someRecords to an array will not work due to the way subsetOfRecords is declared - but I am open to changing it) I'm sure there are plenty of other ideas that I have missed.

• How to parse multiple dates from a block of text in Python (or another language)

  - by mlissner

  I have a string that has several date values in it, and I want to parse them all out. The string is natural language, so the best thing I've found so far is dateutil. Unfortunately, if a string has multiple date values in it, dateutil throws an error: >>> s = "I like peas on 2011-04-23, and I also like them on easter and my birthday, the 29th of July, 1928" >>> parse(s, fuzzy=True) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/pymodules/python2.7/dateutil/parser.py", line 697, in parse return DEFAULTPARSER.parse(timestr, **kwargs) File "/usr/lib/pymodules/python2.7/dateutil/parser.py", line 303, in parse raise ValueError, "unknown string format" ValueError: unknown string format Any thoughts on how to parse all dates from a long string? Ideally, a list would be created, but I can handle that myself if I need to. I'm using Python, but at this point, other languages are probably OK, if they get the job done. PS - I guess I could recursively split the input file in the middle and try, try again until it works, but it's a hell of a hack.

• How can I create an Assembly program WITHOUT using libraries?

  - by Newbie

  Hello. I've literally only just started looking to learn Assembly language. I'm using the NASM assembler on Windows Vista. Usually, when I begin to learn a new language, I'll copy someone else's Hello World code and try to understand it line-by-line. However, I'm finding it suprisingy difficult to find a Hello World program that doesn't reference other libraries! You see, there's no point trying to understand each line of the code if it is closely linked with a whole library of additional code! One of the reasons I want to learn Assembly is so that I can have near complete control over the programs I write. I don't want to be depending on any libraries. And so my question is this: Can anyone give me NASM-compatible Assembly code to a completely stand-alone Hello World program that can output to the Windows Vista console? Alternatively, I appreciate that a library may be required to tell the pogram WHERE to print the output (ie. the Windows console). Other than that, I can't see why any libraries should be required. Am I overlooking anything?

• How do I make a lock that allows only ONE thread to read from the resource ?

  - by mare

  I have a file that holds an integer ID value. Currently reading the file is protected with ReaderWriterLockSlim as such: public int GetId() { _fileLock.EnterUpgradeableReadLock(); int id = 0; try { if(!File.Exists(_filePath)) CreateIdentityFile(); FileStream readStream = new FileStream(_filePath, FileMode.Open, FileAccess.Read); StreamReader sr = new StreamReader(readStream); string line = sr.ReadLine(); sr.Close(); readStream.Close(); id = int.Parse(line); return int.Parse(line); } finally { SaveNextId(id); // increment the id _fileLock.ExitUpgradeableReadLock(); } } The problem is that subsequent actions after GetId() might fail. As you can see the GetId() method increments the ID every single time, disregarding what happens after it has issued an ID. The issued ID might be left hanging (as said, exceptions might occur). As the ID is incremented, some IDs might be left unused. So I was thinking of moving the SaveNextId(id) out, remove it (the SaveNextId() actually uses the lock too, except that it's EnterWriteLock). And call it manually from outside after all the required methods have executed. That brings out another problem - multiple threads might enter the GetId() method before the SaveNextId() gets executed and they might all receive the same ID. I don't want any solutions where I have to alter the IDs after the operation, correcting them in any way because that's not nice and might lead to more problems. I need a solution where I can somehow callback into the FileIdentityManager (that's the class that handles these IDs) and let the manager know that it can perform the saving of the next ID and then release the read lock on the file containing the ID. Essentialy I want to replicate the relational databases autoincrement behaviour - if anything goes wrong during row insertion, the ID is not used, it is still available for use but it also never happens that the same ID is issued. Hopefully the question is understandable enough for you to provide some solutions..

• Managing a log stream in C++ in a cout-like notation

  - by Andry

  Hello! I have a class in c++ in order to write log files for an application of mine. I have already built the class and it works, it is something like this: class Logger { std::string _filename; public: void print(std::string tobeprinted); } Well, it is intuitive that, in order to print a line in the log file, for an object of Logger, it is simply necessary to do the following: Logger mylogger("myfile.log"); mylogger.print(std::string("This is a log line")); Well. Using a method approach is not the same as using a much better pattern like << is. I would like to do the following: Logger mylogger("myfile.log"); mylogger << "This is a log line"; That's all. I suppose I must overload the << operator... But overloading using this signature (the classic one): ostream& operator<<(ostream& output, const MyObj& o); But I do not have a ostream... So, should I do as follows? Logger& operator<<(Logger& output, const std::string& o); Is this the right way? Thanks

• Execute external program from Java

  - by Saurabh Lalwani

  Hi, I am trying to execute a program from the Java code. Here is my code: public static void main(String argv[]) { try { String line; Process p = Runtime.getRuntime().exec( "/bin/bash -c ls > OutputFileNames.txt"); BufferedReader input = new BufferedReader( new InputStreamReader(p.getInputStream())); while ((line = input.readLine()) != null) { System.out.println(line); } input.close(); } catch (Exception err) { err.printStackTrace(); } } My OS is Mac OS X 10.6. If I remove the "> OutputFileNames.txt" from the getRuntime().exec() method, all the file names are printed on the console just fine. But I need it to be printed to a file. Also, if I change the command to: Process p = Runtime.getRuntime().exec( "cmd \c dir > OutputFileNames.txt"); and run it on Windows, it runs and prints the results in the file perfectly fine too. I have read the other posts for executing another application from Java but none seemed to relate to my problem. I would really appreciate any help I can get. Thanks,

• Java/Python: Integration, problem with looping updating text

  - by Jivings

  Hello! Basically I have a script in Python that grabs the text from an open window using getWindowText() and outputs it to the screen. The python loops so as the text in the window changes, it outputs the changes, so the output of the python will always be up to date with the window text. I'm trying to access this text in my Java program by executing the python script as a process and reading the text it outputs using a buffered reader. For some reason this works fine for the first block of text, but will not read any more after this, it wont read any updates to the text as the python outputs it. Can someone shed some light on this? I'm about to try and use Jython, but I'd really like to know what the problem is here... try { Runtime r = Runtime.getRuntime(); Process p = r.exec("cmd /c getText.py"); BufferedReader br = new BufferedReader( new InputStreamReader(p.getInputStream())); int line; while (true) { line = br.read(); System.out.print((char) line); } } catch (Exception e) { e.printStackTrace(); }

• SVG text - total length changes depending on zoom

  - by skco

  In SVG (for web-browsers), if i add a <text>-element and add some text to it the total rendered width of the text string will change depending on the scale of the text. Lets say i add "mmmmmmmmmmmmmmmmmmmmmmmmmmA" as text, then i want to draw a vertical line(or other exactly positioned element) intersecting the very last character. Works fine but if i zoom out the text will become shorter or longer and the line will not intersect the text in the right place anymore. The error can be as much as +/- 5 characters width which is unacceptable. The error is also unpredictable, 150% and 160% zoom can add 3 characters length while 155% is 2 charlengths shorter. My zoom is implemented as a scale-transform on the root element of my canvas which is a <g>. I have tried to multiply the font-size with 1000x and scale down equally on the zoom-transform and vice versa in case it was a floating point error but the result is the same. I found the textLength-attribute[1] which is supposed to adjust the total length so the text always end where i choose but it only works in Webkit. Firefox and Opera seems to not care at all about this value (haven't tried in IE9 yet). Is there any way to render text exactly positioned without resorting to homemade filling of font-outlines? [1] http://www.w3.org/TR/SVG11/text.html#TextElementTextLengthAttribute Update Snippet of the structure i'm using <svg> <g transform="scale(1)"> <!--This is the root, i'm changing the scale of this element to zoom --> <g transform="scale(0.014)"> <!--This is a wrapper for multi-line text, scaling, other grouping etc --> <text font-size="1000" textLength="40000">ABDCDEFGHIJKLMNOPQRSTUVXYZÅÄÖabcdefghijklmnopqrstxyzåäö1234567890</text> </g> </g>

• Sharepoint 2010 start workflow programmatically error

  - by user522429

  I have a workflow associated with a content type. I try to kick it off from code from within the event receiver on the same content type, so when an item is updated, if there is a certain condition (status = ready for review) I start it. //This line does find the workflow association var assoc = properties.Web.ContentTypes["Experiment Document Set"].WorkflowAssociations.GetAssociationByName("Experiment Review Workflow", ultureInfo.CurrentUICulture); //I had tried to use this line from something I found online, but it would return null //var assoc = properties.Web.WorkflowAssociations.GetAssociationByName("Experiment Review Workflow", CultureInfo.CurrentUICulture); var result = properties.Web.Site.WorkflowManager.StartWorkflow(properties.ListItem, assoc, string.Empty, SPWorkflowRunOptions.Synchronous); //The line above gives me this error: System.ArgumentException: Workflow failed to start because the workflow is associated with a content type that does not exist in a list. Before re-starting the workflow, the content type must be added to the list. To check this, I was looking at the content type of the list item being updated and it is correct properties.ListItem.ContentType.Name "Experiment Document Set" So basically I have a workfow associated with the content type "Experiment Document Set". When I try to start a workflow from an event receiver in "Experiment Document Set", I get an error saying the content type "Experiment Document Set" does not exist in the list which doesn't make sense.

• Permission Denied error in IE when closing popups

  - by Kenia

  Hi everyone! I have a simple web testing application which is supposed to open and close several popups by itself (without user interaction). For this purpose i have a javascript function to access the variable where the popup reference is stored and close it if it´s not null, fairly simple. However I get random errors in IE (in FF it works as expected, all popups are closed correctly) like Message: No such interface supported Line: 86 Char: 3 Code: 0 URI: http://10.10.0.61:10000/savmailer/adm/tests/common_tests_code.js and Message: Permission denied Line: 86 Char: 3 Code: 0 URI: http://10.10.0.61:10000/savmailer/adm/tests/common_tests_code.js The line 86 references exactly the point at which I do popup.close(); in the following function function closePopupWindow(popup){ if (popup != null) { popup.close(); popup = null; } } I have googled and it seems this permission denied error is quite common to come through among IE developers, however there´s no clear solution for it, it´s just a matter of changing the code slightly "to please" IE, so to speak. However i have no idea how to change mine since it´s just 3 lines! Tried also to change the security browser settings by adding my domain to the trusted zone, but nothing, doesn't help either. If anyone has any helpful idea or notices something i might be forgetting, please, reply to this! Thanks in advance, Kenia

• Python Beautiful Soup .content Property

  - by Robert Birch

  What does BeautifulSoup's .content do? I am working through crummy.com's tutorial and I don't really understand what .content does. I have looked at the forums and I have not seen any answers. Looking at the code below.... from BeautifulSoup import BeautifulSoup import re doc = ['<html><head><title>Page title</title></head>', '<body><p id="firstpara" align="center">This is paragraph <b>one</b>.', '<p id="secondpara" align="blah">This is paragraph <b>two</b>.', '</html>'] soup = BeautifulSoup(''.join(doc)) print soup.contents[0].contents[0].contents[0].contents[0].name I would expect the last line of the code to print out 'body' instead of... File "pe_ratio.py", line 29, in <module> print soup.contents[0].contents[0].contents[0].contents[0].name File "C:\Python27\lib\BeautifulSoup.py", line 473, in __getattr__ raise AttributeError, "'%s' object has no attribute '%s'" % (self.__class__.__name__, attr) AttributeError: 'NavigableString' object has no attribute 'name' Is .content only concerned with html, head and title? If, so why is that? Thanks for the help in advance.

• How to calculate how many lines (or records) can fit in the given page size

  - by devcoder

  My problem is to calculate the data (string) that can fit into the given page size (in inches). I have an application which creates plain vanilla HTML report without using any reporting controls. Now I have to provide paging support in this report. the report is dynamic in nature i.e. columns are decided at run time. Depending upon the page width, I want to wrap columns in multiple lines. For example, if the page width is 8", i want to fit only first 'n' columns in first line and rest columns can be displayed in second line (or more lines if required). For this I need to calculate how much data can fit in a 8" wide line. Similarly, I want to calculate the height of data that can fit into the given height of page. To summarize, how can I calculate how much data can fit into the given page size in inches. Note: The calculation should also consider the font as it is decided at run time.

• How can I execute a Java program within a php script?

  - by user450775

  I am writing a simple web upload script. The goal is to upload a file using php, and then calling a java program to process this file. I have done the work for uploading the file, but I cannot get a java program to be successfully run from within the php script. I have tried exec(), shell_exec(), and system() with no results. For the command, I have used "java Test", "java < directory /Test", "/usr/bin/java < directory /Test", I have even set up the application as a jar file with no results. The actual line of code I have used is: echo shell_exec("java Test"); Usually there is no output. However, if I have just shell_exec("java"), then the last line of the help from java ("show splash screen with specified image") is displayed, which shows that the command has been executed. If I use, for example, shell_exec("whoami") I get "nobody" returned, which is correct. The only thing the java file does is create a file so that I can see that the application has been successfully run (the application runs successfully if I run it on the command line). I have set the permissions for the java file to 777 to rule out any possibility of permission errors. I have been struggling with this for a while trying all sorts of options with no results - the file is never created (the file is created with an absolute path so it's not being created and I just can't find the file). Does anyone have any ideas? Thanks.

• please help me to solve problem

  - by davit-datuashvili

  first of all this is not homework and nobody tag it as homewrok i did not understand this porblem can anybody explain me?this is not english problem it is just misunderstanding what problem say Consider the problem of neatly printing a paragraph on a printer. The input text is a sequence of n words of lengths l1 , l2 , . . . , ln , measured in characters. We want to print this paragraph neatly on a number of lines that hold a maximum of M characters each. Our criterion of “neatness” is as follows. If a given line contains words i through j , where i = j , and we leave exactly one space between words, the number of extra space characters at the end of the line is M - j + i -(k=i,k< j,k++) lk , which must be nonnegative so that the words fit on the line. We wish to minimize the sum, over all lines except the last, of the cubes of the numbers of extra space characters at the ends of lines. Give a dynamic-programming algorithm to print a paragraph of n words neatly on a printer. Analyze the running time and space requirements of your algorithm.

• How can I quickly parse large (>10GB) files?

  - by Andrew

  Hi - I have to process text files 10-20GB in size of the format: field1 field2 field3 field4 field5 I would like to parse the data from each line of field2 into one of several files; the file this gets pushed into is determined line-by-line by the value in field4. There are 25 different possible values in field2 and hence 25 different files the data can get parsed into. I have tried using Perl (slow) and awk (faster but still slow) - does anyone have any suggestions or pointers toward alternative approaches? FYI here is the awk code I was trying to use; note I had to revert to going through the large file 25 times because I wasn't able to keep 25 files open at once in awk: chromosomes=(1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25) for chr in ${chromosomes[@]} do awk < my_in_file_here -v pat="$chr" '{if ($4 == pat) for (i = $2; i <= $2+52; i++) print i}' >> my_out_file_"$chr".query done

• Grab two parts of a single, short string

  - by TankorSmash

  I'm looking to fill a python dict with TAG:definition pairs, and I'm using RegExr http://gskinner.com/RegExr/ to write the regex My first step is to parse a line, from http://www.id3.org/id3v2.3.0, or http://pastebin.com/VJEBGauL and pull out the ID3 tag and the associated definition. For example the first line: 4.20 AENC [#sec4.20 Audio encryption] would look like this myDict = {'AENC' : 'Audio encryption'} To grab the tag name, I've got it looking for at least 3 spaces, then 4 characters, then 4 spaces: {3}[a-zA-Z0-9]{4} {4} That part is easy enough. The second part, the definition, is not working out for me. So far, I've got (?<=(\[#.+?)) A Which should find, but not include the [# as well as an indeterminded set of characters until it finds: _A, but it's failing. If I remove .+? and replace _A with s it works out alright. What is going wrong? *The underscores represent spaces, which don't show up on SO. How do I grab the definition, ie,(Audio encryption) of the ID3v2 tag from the line, using RegEx?

• How can I use Perl to determine whether the contents of two files are identical?

  - by Zaid

  This question comes from a need to ensure that changes I've made to code doesn't affect the values it outputs to text file. Ideally, I'd roll a sub to take in two filenames and return 1or return 0 depending on whether the contents are identical or not, whitespaces and all. Given that text-processing is Perl's forté, it should be quite easy to compare two files and determine whether they are identical or not (code below untested). use strict; use warnings; sub files_match { my ( $fileA, $fileB ) = @_; open my $file1, '<', $fileA; open my $file2, '<', $fileB; while (my $lineA = <$file1>) { next if $lineA eq <$file2>; return 0 and last; } return 1; } The only way I can think of (sans CPAN modules) is to open the two files in question, and read them in line-by-line until a difference is found. If no difference is found, the files must be identical. But this approach is limited and clumsy. What if the total lines differ in the two files? Should I open and close to determine line count, then re-open to scan the texts? Yuck. I don't see anything in perlfaq5 relating to this. I want to stay away from modules unless they come with the core Perl 5.6.1 distribution.

• The type or namespace name 'WebControls' could not be found (are you missing a using directive or an assembly reference?)

  - by user1467175

  I encountered this error: The type or namespace name 'WebControls' could not be found (are you missing a using directive or an assembly reference?) Source Error: Line 28: Login Login1 = (WebControls.Login)LoginView1.FindControl("Login1"); // here the error code Line 29: TextBox UserName = (TextBox)Login1.FindControl("UserName"); Line 30: TextBox FailureText = (TextBox)Login1.FindControl("FailureText"); I did some research and the solution was to add this into the source code: System.Web.UI.WebControls.Login but I have no idea where this code can be add into. At first I tried putting it as a namespace, but it was wrong. Anyone can tell me where should I place this code at?? EDIT protected void Login1_LoginError(object sender, System.EventArgs e) { //Login Login1 = (WebControls.Login).LoginView1.FindControl("Login1"); Login Login1 = (System.Web.UI.WebControls.Login)LoginView1.FindControl("Login1"); TextBox UserName = (TextBox)Login1.FindControl("UserName"); TextBox FailureText = (TextBox)Login1.FindControl("FailureText"); //There was a problem logging in the user //See if this user exists in the database MembershipUser userInfo = Membership.GetUser(UserName.Text); if (userInfo == null) { //The user entered an invalid username... FailureText.Text = "There is no user in the database with the username " + UserName.Text; } else { //See if the user is locked out or not approved if (!userInfo.IsApproved) { FailureText.Text = "When you created your account you were sent an email with steps to verify your account. You must follow these steps before you can log into the site."; } else if (userInfo.IsLockedOut) { FailureText.Text = "Your account has been locked out because of a maximum number of incorrect login attempts. You will NOT be able to login until you contact a site administrator and have your account unlocked."; } else { //The password was incorrect (don't show anything, the Login control already describes the problem) FailureText.Text = string.Empty; } } }
