  • PHP eval() code in between <?php ?> from database

    - by kr1zmo
    Some of you may be annoyed with this question, and claim it's unsafe blah blah. I want to be able to put php into the database and run it. I have to do this because I store page layouts in the database and each our different for each other, however in some cases I want to use dynamic content for some of the pages. assume $query_from_db is the string returned from the database. php should only eval() the code in between <?php and ?> $query_from_db = '<div> <?php //php to run function dosomething() { //bleh } ?> </div> '; php echo eval($query_from_db);

  • Java - Need help with binary/code string manipulation

    - by ShrimpCrackers
    For a project, I have to convert a binary string into (an array of) bytes and write it out to a file in binary. Say that I have a sentence converted into a code string using a huffman encoding. For example, if the sentence was: "hello" h = 00 e = 01, l = 10, o = 11 Then the string representation would be 0001101011. How would I convert that into a byte? <-- If that question doesn't make sense it's because I know little about bits/byte bitwise shifting and all that has to do with manipulating 1's and 0's.

  • Grabbing Data From Controls In Code Behind

    - by MKell43
    Hopefully this is a pretty simple question for someone to answer. I have a drop down list control that I need to pull the value from in the code behind of the page, modify it and redisplay it. The modifying and redisplaying I've got no problem with, it's grabing the value from the drop down control. Examples in C# would be appreciated as this web app I've been handed is already coded that way. I'm pretty new to .Net so be gentle and I already did some searching via Google and a little bit on the site here, but couldn't find anything that stood out as being the direction to go in to do this.

  • Javascript: Make a static code, dynamic - List of inputs

    - by BoDiE2003
    I have this code, that checks some ids and enable others, the javascript is pretty clear about what it does, but since it corresponds to some specific id ranges, I cant do just a look until it finishes, but I'm looking a way to do this dynamic and save 40 lines of code (or more), since its not the best way. function loopGroup1() { var a = 0; do { $$('.selectedAuthorities-3_' + a).each(function(chk1) { // watch for clicks chk1.observe('click', function(evt) { dynamicCheckbox1(); }); dynamicCheckbox1(); }); a++; } while (a < 4); } function dynamicCheckbox1() { // count how many of group_first are checked, // doEnable true if any are checked var doEnable = ($$('.selectedAuthorities-3_0:checked').length > 0) ? true : false; var doEnable1 = ($$('.selectedAuthorities-3_1:checked').length > 0) ? true : false; var doEnable2 = ($$('.selectedAuthorities-3_2:checked').length > 0) ? true : false; // for each in group_second, enable the checkbox, and // remove the cssDisabled class from the parent label var i = 0; do { $$('.selectedAuthorities-4_' + i).each(function(item) { if (doEnable || doEnable1 || doEnable2) { item.enable().up('li').removeClassName('cssDisabled'); } else { item.disable().up('li').addClassName('cssDisabled'); } }); i++; } while (i < 4); }; /* * * Loop Group 2 * * */ function loopGroup2() { var a = 0; do { $$('.selectedAuthorities-5_' + a).each(function(chk1) { // watch for clicks chk1.observe('click', function(evt) { dynamicCheckbox2(); }); dynamicCheckbox2(); }); a++; } while (a < 4); } function dynamicCheckbox2() { // count how many of group_first are checked, // doEnable true if any are checked var doEnable3 = ($$('.selectedAuthorities-5_0:checked').length > 0) ? true : false; // for each in group_second, enable the checkbox, and // remove the cssDisabled class from the parent label var i = 0; do { $$('.selectedAuthorities-6_' + i).each(function(item) { if (doEnable3) { item.enable().up('li').removeClassName('cssDisabled'); } else { item.disable().up('li').addClassName('cssDisabled'); } }); i++; } while (i < 4); }; /* * * Loop Group 3 * * */ function loopGroup3() { var a = 0; do { $$('.selectedAuthorities-6_' + a).each(function(chk1) { // watch for clicks chk1.observe('click', function(evt) { dynamicCheckbox3(); }); dynamicCheckbox3(); }); a++; } while (a < 4); } function dynamicCheckbox3() { // count how many of group_first are checked, // doEnable true if any are checked var doEnable4 = ($$('.selectedAuthorities-6_0:checked').length > 0) ? true : false; var doEnable5 = ($$('.selectedAuthorities-6_1:checked').length > 0) ? true : false; // for each in group_second, enable the checkbox, and // remove the cssDisabled class from the parent label var i = 0; do { $$('.selectedAuthorities-7_' + i).each(function(item) { if (doEnable4 || doEnable5) { item.enable().up('li').removeClassName('cssDisabled'); } else { item.disable().up('li').addClassName('cssDisabled'); } }); i++; } while (i < 4); }; /* * * Loop Group 4 * * */ function loopGroup4() { var a = 0; do { $$('.selectedAuthorities-9_' + a).each(function(chk1) { // watch for clicks chk1.observe('click', function(evt) { dynamicCheckbox4(); }); dynamicCheckbox4(); }); a++; } while (a < 4); } function dynamicCheckbox4() { // count how many of group_first are checked, // doEnable true if any are checked var doEnable6 = ($$('.selectedAuthorities-9_0:checked').length > 0) ? true : false; var doEnable7 = ($$('.selectedAuthorities-9_1:checked').length > 0) ? true : false; // for each in group_second, enable the checkbox, and // remove the cssDisabled class from the parent label var i = 0; do { $$('.selectedAuthorities-10_' + i).each(function(item) { if (doEnable6 || doEnable7) { item.enable().up('li').removeClassName('cssDisabled'); } else { item.disable().up('li').addClassName('cssDisabled'); } }); i++; } while (i < 4); };

  • bitshift large strings for encoding QR Codes

    - by icekreaman
    As an example, suppose a QR Code data stream contains 55 data words (each one byte in length) and 15 error correction words (again one byte). The data stream begins with a 12 bit header and ends with four 0 bits. So, 12 + 4 bits of header/footer and 15 bytes of error correction, leaves me 53 bytes to hold 53 alphanumeric characters. The 53 bytes of data and 15 bytes of ec are supplied in a string of length 68 (str68). The problem seems simple enough - concatenate 2 bytes of (right-shifted) header data with str68 and then left shift the entire 70 bytes by 4 bits. This is the first time in many years of programming that I have ever needed to do something like this, I am a c and bit shifting noob, so please be gentle... I have done a little investigation and so far have not been able to figure out how to bitshift 70 bytes of data; any help would be greatly appreciated. Larger QR codes can hold 2000 bytes of data...

  • VS2010 is removing code from designer without warning - causing issues

    - by schmoopy
    I have a WinForm with a pretty complex layout (has lots of controls, panels, etc.) Whenever i open the form the file is automatically checked out from source control and it removes anything in the designer file that refereces my menustrip or statusstrip ie: the following get removed (w/o warning) Me.MyMenuStip.SuspendLayout() Me.MyStatusStrip.SuspendLayout() Me.MyMenuStrip.ResumeLayout(False) Me.MyMenuStrip.PerformLayout() Me.MyStatusStrip.ResumeLayout(False) Me.MyStatusStrip.PerformLayout() The code still builds, but there are no Menu or Status items rendered. Any ideas on what i can do? I do not want to just remove/add the menustrip for instance cause i would loose all of my menu items (and there are a lot) Thanks in advance!

  • Explain this O(n log n) algorithm for the Cat/Egg Throwing Problem

    - by ripper234
    This problem (How many cats you need to throw out of a building in order to determine the maximal floor where such a cat will survive. Quite cruel, actually), has an accepted answer with O(n^3) complexity. The problem is equivalent to this Google Code Jam, which should be solvable for N=2000000000. It seems that the O(n^3) solution is not good enough to solve it. From looking in the solutions page, jdmetz's solution (#2) seems to be O(n log n). I don't quite understand the algorithm. Can someone explain it? Edit

  • How to get all n sets of three consecutives elements in an array or arraylist with a for statement ?

    - by newba
    Hi, I'm trying to do a convex hull approach and the little problem is that I need to get all sets of three consecutive vertices, like this: private void isConvexHull(Ponto[] points) { Arrays.sort(points); for (int i = 0; i <points.length; i++) { isClockWise(points[i],points[i+1],points[i+2]); } //... } I always do something that I don't consider clean code. Could please help me find one or more ways to this? I want it to be circular, i.e., if my fisrt point of the a set is the last element in the array, the 2nd element will be the 3rd in the list and the 3rd in that set will be the the 2nd element in the list, and so on. They must be consecutive, that's all.

  • iPython in Emacs. Quick code evaluation

    - by AmV
    Hi all, I would like to "send" code snippets to a iPython interpreter in Emacs 23.2 (Linux). I have two related questions about this: Q1: I have learned that Emacs provides ('shell-command-on-region') to run selected regions in a shell. I have set setq shell-file-name to my iPython path, but when I run M-| after selecting a region, Emacs prompts me the following: Shell command on region: and if I then type RET, I get the iPython man page on the *Shell Command Output* buffer, without the region being executed. Why? Q2: Assuming that I have already started an iPython shell in some other buffer in Emacs, is there a way of selecting a region in another buffer and "sending" this region to the already-started iPython shell? Thanks!

  • Help me understand Dispose() implementation code from MSDN

    - by Benny
    the following code is from MSDN: Idisposable pattern protected virtual void Dispose(bool disposing) { // If you need thread safety, use a lock around these // operations, as well as in your methods that use the resource. if (!_disposed) { if (disposing) { if (_resource != null) _resource.Dispose(); Console.WriteLine("Object disposed."); } // Indicate that the instance has been disposed. _resource = null; _disposed = true; } } why the following statement: _resource = null; _disposed = true; are not enclosed by if (disposing) statement block? for me i would probably write like this: if (disposing) { if (_resource != null) { _resource.Dispose(); _resource = null; _disposed = true; } Console.WriteLine("Object disposed."); } anything wrong with my version?

  • Why Doesn't This Java Code Skip Lines with #?

    - by Nathan
    I'm trying to allow an external .txt file that is read by a Java script be able to have some comments in the beginning of the file so others can easily edit it and add more to it. But if the file contains # (the sign designated for a line that is a comment) it just returns the error that there is a "Format Error in file" (the IOException - so it is getting past that first "IF"...) Can someone help? Here's the portion of the code that deals with commenting lines out of the .txt file being called earlier in the script: while ((line = br.readLine()) != null) { line = line.trim(); if (line.length() < 1 || line.charAt(0) == '#') { // ignore comments continue; } final String[] parts = line.split("="); if (parts.length != 2) { throw new IOException("Format error in file " + JLanguageTool.getDataBroker().getFromRulesDirAsUrl(getFileName()) + ", line: " + line); }

  • MVC Html Layout C# code formatting

Html layout looks more clear to me after that. Do you apply C# formatting rules to <% % html injections "}" should be on a new line or manage layout in different way? Thank you in advance!

  • Analyzing Python Code: Modulus Operator

    - by Bhubhu Hbuhdbus
    I was looking at some code in Python (I know nothing about Python) and I came across this portion: def do_req(body): global host, req data = "" s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect((host, 80)) s.sendall(req % (len(body), body)) tmpdata = s.recv(8192) while len(tmpdata) > 0: data += tmpdata tmpdata = s.recv(8192) s.close() return data This is then called later on with body of huge size, as in over 500,000 bytes. This is sent to an Apache server that has the max request size on the default 8190 bytes. My question is what is happening at the "s.sendall()" part? Obviously the entire body cannot be sent at once and I'm guessing it is reduced by way of the modulus operator. I don't know how it works in Python, though. Can anyone explain? Thanks.

  • code folding in Visual Studio for F#

    - by Yin Zhu
    I find that I tend to write long source files in F#. Some open source projects in F# also have long source files, e.g. FPersec and F# for excel. So it would be very helpful if code folding (even very limited support) is available in VS for F#. E.g. in a module, we can fold out functions that are stable, only leave functions that are subject to change unfold. Is this feature easy to be supported, e.g. by a third party vendor?

  • Add code before initialization of units in Delphi

    - by Alan Clark
    Is there a place where I can add code that will be executed before unit initialization? The reason I want to do this is I need to change the DecimalSeparator, this has to be done before the initialization of some units. I have put it in the project source, before Application.Initialize but it is too late by then. As I see it the only choice I have is to put it in the initialization of the unit that needs the DecimalSeparator to be changed, is this the case? Thanks in advance for any advice.
