• How to view the GDTR's value ?

  - by Mehdi Asgari

  Hi In the book "Rootkit Arsenal" page 84 (Chapter 3) mentions: ..., we can view the contents of the target machine's descriptor registers using the command with the 0x100 mask: kd rM 0x100 and a paragraph below: Note that the same task can be accomplished by specifying the GDTR components explicitly: kd r gdtr .... I run Windbg on my Win XP (inside VMWare) and choose the Kernel Debug - Local. My problem is in case of first command, windbg errors with: lkd rM 0x100 ^ Operation not supported in current debug session 'rM 0x100' and in the second command: lkd r gdtr ^ Bad register error in 'r gdtr' Can anyone guide me ?

• How do I overflow text to the left in a table?

  - by remack

  I have a table with fixed layout. On overflow, the contents of cells should clip from the left instead of the right. That is, if the width of the TD is less than the width of the text, the cell below should display "67890" instead of "12345". This needs to work in IE7+ at minimum. Is there a way to do this in css without any JavaScript? <table style="table-layout:fixed"> <tr> <TD> 12334567890 </TD> </tr> </table>

• Uploading files using HTTP Post Request

  - by Nakago

  Hi All, I want to upload files to a server which is also owned by me. I could think of two ways, of how this can be achieved. Method1: Use HTTP POST request to upload the files. The standard way of uploading files. Method2: Its a two step process. First the client does a POST request with all the details of the file, to the server. Then the server issues Get request(s) onto the client to get the contents of the file. Here method2 seems to be more secure, as the server is in control. The server can request data from the server only when the server feels it to be appropriate, and restrict the amount of data that needs to be transferred. Still i am confused as i am not an expert in this area. Anyone with more hindsight thoughts on this can you please share. Thanks

• Noob Python Question: List Confusion

  - by potatocubed

  I'm trying to transfer the contents of one list to another, but it's not working and I don't know why not. My code looks like this: list1 = [1, 2, 3, 4, 5, 6] list2 = [] for item in list1: list2.append(item) list1.remove(item) But if I run it my output looks like this: >>> list1 [2, 4, 6] >>> list2 [1, 3, 5] My question is threefold, I guess: Why is this happening, how do I make it work, and am I overlooking an incredibly simple solution like a 'move' statement or something?

• Should an edit of a comment be sent through POST or PUT?

  - by the_drow

  I have the following URI: Posts/{postId}/Comments/{commentId} I would like to enable users to edit a comment through my API, should the edit be done with POST or PUT? One one hand, POST updates the contents of a resource so that makes sense but on the other hand PUT replaces it with a new one. So if I understand correctly with POST I need to send only what needs to be updates and with PUT I send the whole resource. Usually in edit forms, the whole resource is loaded anyway so what's the point of using POST? If I take one approach or the other, what are the differences?

• UiScrollView with scrolling content

  - by objektivs

  I have a detail page of type UIScrollView. On it I want an optional UIImageView and a mandatory UITextView. If no image is available then the image view should not take any space. The text for the text view can be of varying sizes. When the view is loaded with, say, the image and the text I need to be able to scroll through all the contents. So the image slips off the top of the screen. I just can't get this work and I feel it ought to be easy. Any ideas?

• Reading from a file into an array in c

  - by NaNa21

  My file contains a series of numbers (integer, float, integer, float ....), each written on a separate line. The numbers of columns are different from one line to another i.e. 1 2.45 3 1.75 5 3.45 7 2.55 9 3.25 6 1.75 4 3.55 6 2.55 9 2.45 The program should read the contents of the entire file and place the data into an array of type float with an entry for each line. Here is my basic solution, but this is only suitable if I have fixed no of columns. float Read(FILE *pFile) { char line[50]; char letter[5]; fi = fopen("file.txt", "r"); while (fgets(line,200,fi)!=NULL) { sscanf(line,"%f %f %f",&a[i], &a2[i],&a3[i]); printf("%2.0f %2.5f %2.0f\n",a[i],a2[i],a3[i]); } fclose(fi); return a[i]; } Please HELP.

• Javascript Getting specific element (of parent) by name

  - by Fluidbyte

  I'm using custom tags to define sections in an application, so I have something like this: <mysection> <form> <input name="myfield"> </form> </mysection> I'm using the following and able to get the tag (printed to console, everything is groovy) var parent = document.getElementsByTagName('mysection'); The issue I'm having is finding the child field by name: var myfield = parent.getElementsByName("myfield"); ...as I don't want to pick up on any other 'sections' that might have an input with the name 'myfield'. EDIT: var parent = document.getElementsByTagName('mysection')[0]; was suggested and returns to console the section contents, however, getElementsByName throws an error: Uncaught TypeError: Object #<NodeList> has no method 'getElementsByName'

• Manipulate DOM before it is shown to the user?

  - by user246114

  Hi, I'm not too familiar with javascript, is there a way to manipulate the DOM before the page is displayed to the user? I'm using GWT which makes you create the page elements via javascript. This is kind of convenient, but it appears that all the javascript code is executed after the page is first shown to the user. This has the effect of showing the page as a blank white screen, then all the UI elements popping onto screen. The effect is really apparent when switching between pages. If I were using php or jsp, it looks like the page ui elements are already prerendered and the browser won't show a blank white screen before display. So is there any hook in javascript where we can manipulate the DOM before the browser clears out the contents of the last page shown? Thanks

• "Inlining" (kind of) functions at runtime in C

  - by fortran

  Hi, I was thinking about a typical problem that is very JIT-able, but hard to approach with raw C. The scenario is setting up a series of function pointers that are going to be "composed" (as in maths function composition) once at runtime and then called lots and lots of times. Doing it the obvious way involves many virtual calls, that are expensive, and if there are enough nested functions to fill the CPU branch prediction table completely, then the performance with drop considerably. In a language like Lisp, I could probably process the code and substitute the "virtual" call by the actual contents of the functions and then call compile to have an optimized version, but that seems very hacky and error prone to do in C, and using C is a requirement for this problem ;-) So, do you know if there's a standard, portable and safe way to achieve this in C? Cheers

• Pointers in C with binary file

  Hi All, I am reading the contents of the file using fread into an char array. But I am not sure why it is not getting printed in the output. Here is the code: void getInfo(FILE* inputFile) { char chunk[4]; int liIndex; for (liIndex = 0 ; liIndex < 4 ; liIndex++) { fread(chunk, sizeof(char), 4, inputFile); } printf("\n chunk %s", chunk); } Output prints nothing at all. Where am I going wrong? Regards , darkie

• Trying to exlcude VTI* paths in MSIDXS sql select statement

  - by Catdirt

  Hi, using a c# asp.net page, building a SQL query string to run against an index server catalog: string SQL = "SELECT doctitle, vpath, Path, Write, Size, Rank "; SQL += "FROM \"" + strCatalog + "\"..SCOPE() "; SQL += "WHERE"; SQL += " CONTAINS(Contents, '" + strQP + "') "; SQL += "AND NOT CONTAINS(Path, '\"_vti_\"') "; SQL += "AND NOT CONTAINS(FileName, '\".ascx\" OR \".config\" OR \".css\"') "; SQL += "ORDER BY Rank DESC"; Seems to work fine, except it will return results in the _vti_ directories which I am trying to avoid. Edit: All but asked question, so to be technical: How can I search the index and have it not return files from the vti folders? Switching to use an ixsso query object is possible, but i'd rather avoid it for this particular instance.

• How do I get back results running a VB Script from C#?

  - by Tom

  I want to be able to call VB scripts from C#, which is easy enough, but I need to be able to get back the results from these scripts at times. Should I use the method referenced with something to read back, or should I use a different method? I've found a method to getting data back from powershell scripts using Runspaces and Pipelines, but I don't know enough about this technology to know if it will work with VB scripts as well. Ideally, I'd like to do something similar to the powershell method where I can just pass in the contents of the script without needing to reference an external file and get back the results. Can anyone tell me how to do this? Thanks.

• Changing populated DataTable column data types

  - by TonE

However, the column data types of the DataTable need to be changed to match the schema of the target database table, handling null values. I am not very familiar with ADO.NET so have been search for a clean way of doing this? Thanks.

• PHP export to excel

  - by user1865240

  I'm having a trouble that I can't export japanese texts to excel (xls). I used the following codes: header('Content-type: application/ms-excel;charset=UTF-8'); header('Content-Disposition: attachment; filename='.$filename); header("Pragma: no-cache"); echo $contents; But in the excel file, the text changed to funny characters like this: é™?定ç‰? ã?¨ã??ã?¯ã??ã?£ã?†ã?ªã?¢å??犬ã?®ã?Œæ??ã? ’è??ã??ã?Ÿã?†ã?£ã??ã??ã??ã?? ï?? Currently, I'm using hostingmanager and I tried on the different server using the same codes and there's no problem. What could be the problem. Because of the PHP version?? Please help me. Thank you, Aino

When I do a print_r($matches), it shows the right results but when I use $matches[1], it browser tells me that there is no such index.

• Simple: replace div with ajax content (jquery)

  - by user469110

  I followed this thread. I now have: <a href="#" onclick="$('#gc').load('test');">reload</a>... </span> <div id="gc"> empty </div> This is what I am getting: Uncaught exception: TypeError: Cannot convert '$('#gc')' to object Error thrown at line 1, column 0 in <anonymous function>(event): $('#gc').load('test'); What is that? I thought I would be able to select a div and replace the contents with load()?

• PHP - Get values from Array

  - by danit

  I am trying to get a record from a database using an sql lookup (sql1). This then returns as an array which is fine, but I need to use part of the array for my next stage. $opt=get_records_sql($sql1); //Diags for SQL content print_object($opt); $n = count($opt); if (empty($opt)) { echo 'No options selected'; } else { $optno = $opt["subjectid"]; // Diags of $optno echo '<br>$optno = '.$optno; As you can see, I tried to use this: $opt["subjectid"] as subjectid is the fieldname that I am trying to access and I was under the impression that this was correct for accessing an array, but I get the following error: Notice: Undefined index: subjectid Array contents: Array ( [1] => stdClass Object ( [uname] => JHollands06 [tutor] => M LSt [subjectid] => 1 [year] => 2010 [optid] => 1 ) )

• Ruby - overriding/enabling multiple assignment (e.g. `a, b, c = d, e, f`)

  - by nicholaides

  In ruby, you can do this: d = [1, 2, 3] a, b, c = d a, b, and c, will receive the values 1, 2, and 3, respectively. d, in this case in an Array and ruby knows to assign it's contents to a, b, and c. But, if d were a Fixnum, for example, only a would be assigned to the value of d while b and c would be assigned nil. What properties of d allow it to be used for multiple assignment? In my exploring so far, I've only been able to make instances of subclasses of Array behave in this way.

  With a query such as: SELECT * FROM images WHERE id IN (12,9,15,3,1) is it possible to order the results by the contents of the IN clause? The result I'm looking for would be something like: [0] => Array ( [id] => 12 [file_name] => foo ) [1] => Array ( [id] => 9 [file_name] => bar ) [2] => Array ( [id] => 15 [file_name] => baz ) ...

• QuickPdf - Memory leak

  - by Lonzo

  I have a method containing code to create a pdf doc using the QuickPdf library. Inside the method, I instantiate a QuickPdf object, create the pdf doc and save it to a file. I then call this method for each file to be generated. Now my problem is that the pdf docs' sizes are increasing with each call to the method even though the contents are basically the same . I am suspecting a memory leak but I cant see where exactly, since the QuickPdf object is being created and disposed each time on each call.

• How can I get the file extensions from relative links in HTML text using Perl?

  - by Structure

  For example, scanning the contents of an HTML page with a Perl regular expression, I want to match all file extensions but not TLD's in domain names. To do this I am making the assumption that all file extensions must be within double quotes. I came up with the following, and it is working, however, I am failing to figure out a way to exclude the TLDs in the domains. This will return "com", "net", etc. m/"[^<>]+\.([0-9A-Za-z]*)"/g Is it possible to negate the match if there is more than one period between the quotes that are separated by text? (ie: match foo.bar.com but not ./ or ../) Edit I am using $1 to return the value within parentheses.

• Python if statement not working as expected

  - by Chris Esposito

  I'm searching for a string in a website and checking to see if the location of this string is in the expected location. I know the string starts at the 182nd character, and if I print temp it will even tell me that it is 182, however, the if statement says 182 is not 182. Some code f = urllib.urlopen(link) #store page contents in 's' s = f.read() f.close() temp = s.find('lettersandnumbers') if (htmlsize == "197"): #if ((s.find('lettersandnumbers')) == "182"): if (temp=="182"): print "Glorious" doStuff() else: print "HTML not correct. Aborting." else: print htmlsize print "File size is incorrect. Aborting."
