• Subversion repo upgrade makes repository unusable.

  - by Mike C.

  Hi, I recently upgraded my subversion server from 1.4.6 to 1.6.11. The repos all seem to work correctly after this. I then try to upgrade a repo by issuing the svnadmin update command, and it produces no errors and says the update is complete. However, I am unable to open the repository after this. I get the following error when trying to open the repo: Could not open the requested SVN filesystem. I am using Apache, not SVNServe. Any help would be appreciated!

• including a string as a parameter to a function in a header file? c++

  - by Nara

  hello everyone, total newbie is here :) i have this header file, zeeheader.h, and i wrote some classes in it, i'm having problems giving a string as a parameter to one of the functions: class DeliTest { public: void DeliCheck(Stack*,string); void ComCheck (unsigned,string); bool EofCheck (unsigned,string); }; as i was implementinng it in the cpp file, i added #include to it, it seemed to be working, for example : as i was writing the "data." i got the "length()" appear by the intellisense, so i thought that it was working, but it wasn't. i got errors like: syntax error : identifier 'string' overloaded member function not found in 'DeliTest' this is one of the fucntions in the cpp file: bool DeliTest::EofCheck(unsigned i, string data) { if (i == data.length()-1) return 1; return 0; } am i supposed to be adding something to the header file??

• VS2010 (older) installer project - two or more objects have the same target location.

  - by Hamish Grubijan

  This installer project was created back in 2004 and upgraded ever since. There are two offending dll files, which produce a total of 4 errors. I have searched online for this warning message and did not find a permanent fix (I did manage to make it go away once until I have done something like a clean, or built in Release, and then in Debug). I also tried cleaning, and then refreshing the dependencies. The duplicated entries are still in there. I also did not find a good explanation for what this error means. Additional warnings are of this nature: Warning 36 The version of the .NET Framework launch condition '.NET Framework 4' does not match the selected .NET Framework bootstrapper package. Update the .NET Framework launch condition to match the version of the .NET Framework selected in the Prerequisites Dialog Box. So, where is this prerequisites box? I want to make both things agree on .Net 4.0, just having a hard time locating both of them.

• Makefile won't copy .o to obj/ and target to bin/ folders

  - by about blank

  I'm trying to write a Makefile which will copy its target and objects to bin/ and obj/ directories, respectively. Yet, when I try to run it I get the following error: nasm -f elf64 -g -F stabs main.asm -l spacelander.lst ld -o spacelander obj/main.o ld: cannot find obj/main.o: No such file or directory make: *** [spacelander] Error 1 Why is this happening? Update I noticed when I posted the error that it was due to white spacing errors. After taking care of those, I still get the new error I replaced with the old one I mentioned prior. What is this?? Update 2 Posted -d flag output below Makefile source. Source ASM := nasm ARGS := -f FMT := elf64 OPT := -g -F stabs SRC := main.asm OBJDIR := obj TARGETDIR := bin OBJ := $(addprefix $(OBJDIR)/,$(patsubst %.asm, %.o, $(wildcard *.asm))) TARGET := spacelander .PHONY: all clean all: $(OBJDIR) $(TARGET) $(OBJDIR): mkdir $(OBJDIR) $(OBJDIR)/%.o: $(SRC) $(ASM) $(ARGS) $(FMT) $(OPT) $(SRC) -l $(TARGET).lst $(TARGET): $(OBJ) ld -o $(TARGET) $(OBJ) clean: @rm -f $(TARGET) $(wildcard *.o) @rm -rf $(OBJDIR) make -d Output - NOTE: output is too many characters for body, thus is pastebinned http://pastebin.com/3bctGJxs

• Datepicker (1.8rc3) not transferring date in IE6

  - by brianjcohen

  Using jquery-1.4.2 and jquery-UI 1.8rc3, I instantiated a datepicker on a text input with showOn: 'focus'. The datepicker appears correctly. However when I click on a date, the datepicker doesn't disappear and the dateStr doesn't get transferred to the text input. I tried adding an onClose: handler that calls alert(dateStr). The event fires but no dateStr has been set. Everything works fine in Firefox. I have Microsoft Script Debugger installed but no script errors were detected. I did report this as a potential problem at the jQuery UI forums but my message has been sitting there awaiting moderation for hours and I figured someone here might have a suggestion. $().ready(function() { $(".date").datepicker({ showOn: 'focus', onClose: function(dateText) { alert(dateText); } }); });

• JavaScript: filter() for Objects

  - by AgileMeansDoAsLittleAsPossible

  ECMAScript 5 has the filter() prototype for Array types, but not Object types, if I understand correctly. How would I implement a filter() for Objects in JavaScript? Let's say I have this object: var foo = { bar: "Yes" }; And I want to write a filter() that works on Objects: Object.prototype.filter = function(predicate) { var result = {}; for (key in this) { if (this.hasOwnProperty(key) && !predicate(this[key])) { result[key] = this[key]; } } return result; }; This works when I use it in jsfiddle (http://jsfiddle.net/MPUnL/4/), but when I add it to my site that uses jQuery 1.5 and jQuery UI 1.8.9, I get JavaScript errors in FireBug.

• Load a dll library on Java

  - by crimson_king

  I need to load a library written in C on java. I have only dlls and header files. Since I didn't understand how to translate pointers or other derivated types from JNI documentation I tried to use an automating tool for this, gluegen and SWIG, but I couldn't manage on how to use them. I tried to create an interface file for SWIG but it only gives errors. Is there an example on how to load a dll to a java program using ANY tool that works and can generate translated C function and types from .h files ?

• Creating problem-sets with answers in Latex

  - by ARV

  Hello everyone. I want to typeset Mathematical problem-sets in Latex. My requirements are as follows: When I type them in, I want the questions and the answers to be next to each other in the source-code so that fixing errors, etc. can be done easily. However, when the document is typeset, I want the answers to appear in a separate "Answers" section just the way they do in textbooks. Does anyone know of a way to do this? Many thanks in advance!

• Are there any alternative to the header(); function ?

  - by Simon

  The thing is, I have a log-in page. And, when user enters Username & Password, they must be re-directed to success/failure page. Now, I have placed a "header('location:welcome.php');" after mysql rows are returned. But, it is giving me Header already sent errors, and I don't know much about PHP to do anything about it, let alone understand why it is happening. So, how to you transfer a user to another page after log-in data is verified? Same problem is happening with register, post, comment and search functions in my site.

• Why does var evaluate to System.Object in "foreach (var row in table.Rows)"?

  - by DanM

  When I enter this foreach statement... foreach (var row in table.Rows) ...the tooltip for var says class System.Object I'm confused why it's not class System.Data.DataRow. (In case you're wondering, yes, I have using System.Data at the top of my code file.) If I declare the type explicitly, as in... foreach (DataRow row in table.Rows) ...it works fine with no errors. Also if I do... var numbers = new int[] { 1, 2, 3 }; foreach (var number in numbers) ...var evaluates to struct System.Int32. So, the problem is not that var doesn't work in a foreach clause. So, there's something strange about DataRowCollection where the items don't automatically evaluate to DataRow. But I can't figure out what it is. Does anyone have an explanation?

• g++ library search failure

  - by Frederick

  I have a directory structure as below: / | +--- /lib | libsomething.a | libsomething.so | +----/obj anObjFile.o When I run the following command from within the obj directory: g++ -L../lib -lsomething anObjFile.o I get undefined reference errors. Apparently gcc is failing to locate libsomething.a. But now if I delete libsomething.so and then rerun the command, linking succeeds. As per gcc documentation -lsomething should expand to libsomething.a. Then why is presence of libsomething.so causing the library search to fail? Also, how can I resolve this problem? I'm on Linux Mint 12 with gcc version 4.6.1.

• Can't type anything in inputs or textareas

  - by dev reactive.by

  Hello, I have a problem: I've add a Jquery UI drag-n-drop widget to my page, but after that I can't type anything into inputs or textareas. I use jQuery 1.4.2 and jQuery UI 1.8rc3, and tiny_mce for convert textareas into WYSIWUG editor (I've tried to disable tiny_mce). When I put $("input").click( function(){ alert('clicked!'); }); - it's working(I have an alert). When I get focused to any input I even can't refresh page by F5 and go to the next element by Tab key. There's a page: http://cms.reactive.by/test.htm (click to clip2net.com/clip/m7787/1269022358-clip-3kb.png to see that jQuery UI is workong) And yes.. there's no errors in FireBug. I hope You can help me to understand what's wrong with this code.

• mysql_close(): supplied argument is not a valid MySQL-Link resource

  - by maxedison

  I'm trying to get the hang of using custom session handlers to store session data in a MySQL database. However, I keep getting the following warning: mysql_close(): supplied argument is not a valid MySQL-Link resource Here's the code I'm using, which I got from here: function _open(){ global $_sess_db; $_sess_db = mysql_connect("localhost", "root", "******"); if ($_sess_db) { return mysql_select_db('style', $_sess_db); } return false; } function _close(){ global $_sess_db; return mysql_close($_sess_db); //error happens here } The full text of the error message ultimately points to the final "return mysql_close($_sess_db);" line. I can confirm that the mysql_connect info does in fact work, and I do have the rest of the session handler functions defined as well. And in case it helps, I get these errors immediately upon page load, without actually calling any of the session handler functions, and without having any current sessions open.

• scrollTop issue on constant moving div

  - by joe

  I have a FLASH object that I mouse over which in turn calls the following function to scroll a div. It works but due to the constant high speed scrolling it would throw up NULLS. This in turn caused IE to open a new page through my FLASH ActionScript 2.0 I found that by creating the SC variable and throwing in the condition "if it exists" keeps FLASH from causing IE to open a new page. However, it still creates an error behind the scenes of "Object Required". Although my application works I do not want load up memory with errors. Any thoughts? var SC; function pP(PT){ SC=document.getElementById('P'+PT).offsetTop; if(SC){document.getElementById('CBOX').scrollTop=SC;} }

• Why does php's file_get_contents incorrectly retrieve json files from xkcd?

  - by hally

  In writing a PHP script to download xkcd comics, i incurred errors when trying to get specific comics (as opposed to the latest one). Specifically, pointing file_get_contents at the following url: xkcd.com/$COMIC_NUM/info.0.json inexplicably retrieved the xhtml version of the comic's page on xkcd.com, and not a JSON file. However, if i request the exact same url in my browser, the correct JSON file is downloaded. I'm not sure why this is happening, but i suspect it has something to do with the request headers being sent. Please help! :S

• Error including errno.h

  - by TechWiz

  Every time I try to compile a project that includes errno.h in linux, I get issues using the error codes. GCC spits out errors saying the error codes aren't declared and I get the same issue with 3rd party projects that are, of course, known to compile. I have the Linux headers for my kernel installed. Any suggestions as to what else it could be? edit: Snippet at error code: if ((res != 0) && (errno == EEXIST)) Snippet of includes: ... #include <dirent.h> #include <errno.h> #include <stdarg.h> ... as is with no ifdef edit: Well I'm convinced my system's Linux headers are hosed somehow... that, or I'm missing some environment vars.

• Git pull: error: Entry foo not uptodate. Cannot merge.

  - by yuit

  I'm trying to update my repo from a remote branch and keep getting this error when I do a "git pull". I haven't made any local changes, and even if I have I don't need to keep them. I've tried: git reset --hard and I get the same problem The only thing that seems to work is deleting the offending file and try a git pull again. I've also tried "git stash" followed by a "git pull". No go. edit: using PortableGit-1.6.4-preview20090729 so any previous bugs with spurious errors should be fixed.

• (Rails) How do I reference resources from non-restful views...?

  - by humble_coder

  Hi All, How do you ensure that your javascript includes get included properly for all files everywhere using a particular layout? Basically I have some non-restful actions that I've added. I haven't added any ROUTES for them, however, using normal text rendering works fine. It's when I start requiring different "swf" and "js" files (files which are properly placed in PUBLIC) that things get hairy. I start receiving "406 Not Acceptable" errors telling me that it's looking for the files in a subdirectory of the current controller. As it stands I'm in including the JS in "application" layout file. It works for the INDEX action, but doesn't seem to work for any of the non-restful actions. Thoughts?

• Strings in ASP?

  - by TSL

  Hi All, I have some APSX code that I am trying to modify for a programmer that is out on medicaly leave. I am not an ASP guy, but rather C++ So what I want to do is delare a string, check the first 4 characters and if it is 'http' do something, if not, something else. Here is what I have: string strYT= Left(objFile, 4); if (strYT=="http") { pnlYT.Visible = true; pnlIntro.Visible = false; pnlVideo.Visible = false; } else { pnlYT.Visible = false; pnlIntro.Visible = false; pnlVideo.Visible = true; PrintText(objFile); } But I get errors like: Compiler Error Message: CS0103: The name 'Left' does not exist in the class or namespace 'ASP.zen_aspx' My googling turns up many examples of doing it just like this.....

• C# method contents validation

  - by user258651

  I need to validate the contents of a C# method. I do not care about syntax errors that do not affect the method's scope. I do care about characters that will invalidate parsing of the rest of the code. For example: method() { /* valid comment */ /* <-- bad for (i..) { } for (i..) { <-- bad } I need to validate/fix any non-paired characters. This includeds /* */, { }, and maybe others. How should I go about this? My first thought was Regex, but that clearly isn't going to get the job done.

• Does 'throw' or 'try...catch' hinder performance?

  - by Richard

  I've been reading all over the place (including here) about when exception should / shouldn't be used. I now want to change my code that would throw to make the method return false and handle it like that, but my question is: Is it the throwing or try..catch-ing that can hinder performance...? What I mean is, would this be acceptable: bool method someMmethod() { try { // ...Do something catch (Exception ex) // Don't care too much what at the moment... { // Output error // Return false } return true // No errors Or would there be a better way to do it? (I'm bloody sick of seeing "Unhandled exception..." LOL!)
