• Javascript is called in IE and FF but not in Chrome, why?

  - by JPJedi

  I have the following code below for a button on an aspx page. When it is clicked it should call a javascript that will print the text in that div. Everything works great in IE & Firefox but when it is tried in chrome it is as if the OnClientClick is not kicking off the javascript. I receive no errors and it works in IE and FF now. Below is the code for the button that calls the javascript. <asp:Button ID="btnEULAPrint" Text="Print" runat="server" ValidationGroup="EULA" OnClientClick="javascript:CallPrint('EULA');return false;"/> Anyone have any ideas or links they could share to point me in a direction? Thanks

• Problem exporting SQL Server management Studio Express to Go Daddy

  - by brohjoe

  I'm having a terrible time exporting SQL Server Management Studio Express tables to the Go Daddy webserver. Go Daddy support can't help either. I started by using Microsoft Database Publishing Wizard for SQL Server thinking it would be 'easy'....not! I ran into user/password errors even though I was using the user and password that was created for the SQL database in the Go Daddy site. I called help desk support at Go Daddy and went through several iterations of processes to get the thing working but it didn't. Finally, the support guy acted like his phone went on the blip and scuttled away. There has got to be someway to upload SQL Server to a webserver without a lot of drama. Any suggestions?

• Problem with autocommit in ANT SQL task

  - by Alex Stamper

  I have an SQL script and want to apply it witn ANT task. This script clears out schema, creates new tables and views. The ANT defined task as follows: <sql driver="com.mysql.jdbc.Driver" url="jdbc:mysql://host:3306/smth" userid="smth" password="smth" expandProperties="false" autocommit="true" src="all.sql" > </sql> When this task launches, it shows in log that tables are cleared and created. But when it tries to create first view, it fails with: Failed to execute: CREATE VIEW component... AS SELECT component_raw.id AS MySQLSyntaxErrorException: Table 'component_raw' doesn't exist I have no idea why it fails here. Running this all.sql from MySQL query browser gives no errors. When I launched ANT with -v option, I didn't see any "COMMIT" messages.. Please, help to resolve the problem.

• nested if: too many arguments?

  - by FLX

  For some reason this code creates problems: source="/foo/bar/" destination="/home/oni/" if [ -d $source ]; then echo "Source directory exists" if [ -d $destination ]; then echo "Destination directory exists" rsync -raz --delete --ignore-existing --ignore-times --size-only --stats --progress $source $destination chmod -R 0755 $destination else echo "Destination directory does not exists" fi else echo "Source directory does not exists" fi It errors out with: Source directory exists /usr/bin/copyfoo: line 7: [: too many arguments Destination directory does not exists I used nested if statements in bash before without a problem, what simple mistake am I overlooking? Thanks!

• Use of COM object in IIS 7

  - by Wouter d.A.

  Hi all, I am currently moving an ASP.NET web-project from an IIS 6 to a IIS 7 hosting environment. Everything seems to be running OK, except my calls to a COM object. I can perfectly instantiate an object of the COM type, but when I call one of its methods, the IIS crashes. The event log reports an error code "0xc0000374", which indicates a heap corruption. When I run the application inside the visual studio development server, everything goes well and the COM object code gets executed without any errors. This is also the case when the application is hosted on an IIS 6 machine. I have looked through all settings of the IIS 7 and have not found anything configurable for COM objects, like security or ... I have been struggling with this for a while and I'm out of ideas. Does anyone have any experience deploying COM objects on IIS 7? Your help would be very appreciated!

• Garbage collecting at ColdFusion CFC

  - by Sergii

  Hello. I have a CFC as singletone object in Application scope. One of the methods is used for massive data processing and periodically causes the "Java heap space" errors. EDIT All variables inside the method are VAR-scoped, so they should not be kept in the object scope when invokation ended. It can be a bit dumb question for Java people, but I'd like to know how Java garbage collector cleans up the CFC methods memory: only when whole request ends, or maybe right after each method/function invokation? Second option is interesting because it can allow me to split my large method into the few, as one of the possible optimizations.

• How exactly is a PHP script executed?

  - by alex

  I was just thinking to myself "How exactly is a PHP script executed?" I thought it was parsed first for syntax errors etc, and then interpreted and executed. However, I don't know why I believe that is correct. I'm probably wrong. So, how exactly is a PHP file interpreted and executed? What stages does this involve? How do included files fit into the parsing of the script? This is just to help me get my head around it. I'm interested and can not find a good answer with Google. Thanks!

• XCode Syntax Coloring Broken

  - by sw12345

  XCode frequently seems to lose it's mind, and doesn't color code system classes or provide correct "code sense" suggestions. This is endlessly frustrating. The question has been asked on at least three other occasions: http://stackoverflow.com/questions/2263994/problems-with-xcode-syntax-highlighting http://stackoverflow.com/questions/1627033/xcode-code-sense-color-completion-not-working http://stackoverflow.com/questions/2138047/xcode-code-loses-syntax-coloring I have switched by project version to/from 3.1-compatiable and 3.2-compatiable, completely restarting XCode before and after each change with no effect. I have rebuilt the code sense indexes and completely restarted XCode with no change. I have built my project to make sure there are no errors and restarted. I have copied my files (sans .svn files) to a different location - same problem. I've already completely disabled the argument "placeholders" because they screw up my documents when i type too fast... all I'm asking for is for the "esc" key to display the correct list of properties and methods.

• Reference Error for property of Javascript Object

  - by Jeremy Petzold

  I have built an object in Javascript on the Google Apps Script engine and every time I run my script I get a reference error saying uName is not defined. Here is the relivant code: function DataSet() { this.uName = ""; this.dFeild = ""; this.qUrl = "http://api.bfbcs.com/api/pc?players="+uName+"&fields="+dFeilds; this.data = ""; this.dQuery = dQuery; this.execQuery = execQuery; According to all sources I have found, I should not need to use the keyword var, and when I do include that, it throws other errors. What could be going on? Thanks

• How do I test ActionFilterAttributes that work with ModelState?

  - by Tomas Lycken

  As suggested by (among others) Kazi Manzur Rashid in this blog post, I am using ActionFilterAttributes to transfer model state from one request to another when redirecting. However, I find myself unable to write a unit test that test the behavior of these attributes. As an example, this what I want the test for the ImportModelStateAttribute to do: Setup the filterContext so that TempData[myKey] contains some fake "exported" ModelState (that is, a ModelStateDictionary I create myself, and add one error to) Make ModelState contain one model error. Call OnActionExecuting. Verify the two dictionaries are merged, and ModelState now contains both errors. I'm at a loss already on the second step.

• How to configure tomahawk and trinidad to work together

  - by ashtaganesh

  Hi, I am new to JSF. I want to use inputListOfValues component from Trinidad in my application which also uses Tomahawk. I have added the required jars for Trinidad and before getting inputListOfValues I tried one simple inputText to be printed on browser using Trinidad. I was not getting any configuration errors but it was not printing the corresponding text on browser. So I wonder if I can use tomahawk and trinidad together ? If yes, is there any configuration setting we need to do for this ? Any help will be greatly appreciated. Thanks, Ganesh.

• Difference between piping a file to sh and calling a shell file

  - by Peter Coulton

  This is what was trying to do: $ wget -qO- www.example.com/script.sh | sh which quietly downloads the script and prints it to stdout which is then piped to sh. This unfortunately doesn't quite work, failing to wait for user input a various points, aswell as a few syntax errors. This is what actually works: $ wget -qOscript www.example.com/script.sh && chmod +x ./script && ./script But what's the difference? I'm thinking maybe piping the file doesn't execute the file, but rather executes each line individually, but I'm new to this kind of thing so I don't know.

• Can't set default value of string property to "" in the Xcode CoreData model designer

  - by glenc

  I have an entity in my datamodel with a string property that is currently optional, and I'd like to convert this property to a required property with a default value of the empty string. As others have discovered, leaving the default value blank results in validation errors (since the designer interprets this as NULL), but trying '', "", or @"" as the default value results in those literal characters being interpreted as the default, rather than the empty zero-length string, as desired. I did find this thread on Google, however, apart from the solution being really ugly (model definition split between the .xcdatamodel and objc source), it also doesn't work for lightweight migrations because those migrations are done solely based on the .xcdatamodel files and the objc logic from your entity implementations isn't loaded. Is there any way to achieve this in the data model designer?

• What's the best way to detect web applications attacks ?

  - by paulgreg

  What is the best way to survey and detect bad users behavior or attacks like deny of services or exploits on my web app ? I know server's statistics (like Awstats) are very useful for that kind of purpose, specially to see 3XX, 4XX and 5XX errors (here's an Awstats example page) which are often bots or bad intentioned users that try well-known bad or malformed URLs. Is there others (and betters) ways to analyze and detect that kind of attack tentative ? Note : I'm speaking about URL based attacks, not attacks on server's component (like database or TCP/IP).

• python appengine form-posted utf8 file issue

  - by khany

  hi, i am trying to form-post a sql file that consists on many INSERTS, eg. INSERT INTO `TABLE` VALUES ('abcdé', 2759); then i use re.search to parse it and extract the fields to put into my own datastore. The problem is that, although the file contains accented characters (see the e is a é), once uploaded it loses it and either errors or stores a bytestring representation of it. Heres what i am currently using (and I have tried loads of alternatives): form = cgi.FieldStorage() uFile = form['sql'] uSql = uFile.file.read() lineX = uSql.split("\n") # to get each line and so on. has anyone got a robust way of making this work? remember i am on appengine so access to some libraries is restricted/forbidden

• struts validation problem in IE

  - by user265201

  I am using Struts 2.1.8 and facing validation problem in IE. I am getting the following error An exception occurred: Error. Error message: Invalid argument. I tried out to figure out the cause and found the following. My generated javascript code is: field = form.elements['district.name']; var error = "Enter only alphabets for district"; if (continueValidation && field.value != null && !field.value.match("^[a-zA-Z ]*$")) { addError(field, error); errors = true; } I tried to mock up by putting the same code in a function and calling it in onclick event. The method addError() throws the exception and the reason is field variable. If I change it to field[0], it works fine. How to fix this error?

• Can I get build warnings from a custom build step in Qt Creator?

  - by Derick

  I have the following script that I run as a custom build step in Qt Creator: git ls-files . | egrep "\.cpp$|\.h$" | xargs vera++ Which then gives output: foo/bar.cpp:1: no copyright notice found Another script I also use is: cppcheck . --template gcc -q --enable=style,unusedFunctions With the output: apple.h:8: style: The class 'MyPie' has no constructor. Member variables not initialized. I would love to double-click on the error and go to the source in the Compile Output window. It seems that only gcc errors are detected and these custom ones are ignored even though they have the same format.

• VB.Net variable declaration

  - by dcp

  I notice that both of these compile without any compiler warnings or errors, even with Option Strict and Option Explicit both turned on: Dim x As Exception = New Exception("this is a test") Dim y = New Exception("this is another test") My question is, is it more proper to use the first way (see variable x) or the second way (see variable y)? My guess is that VB doesn't need the As clause since the variable is being initialized in place, so the compiler can infer the type. I tend to like the first way as it just "feels" right and is more consistent with other languages like C#, just wondered if there was some good reason for one way over the other. I guess it's really personal choice.

• 500 error for long url iis7

  - by Chris Porter

  I was getting 404 errors for some long URLs on a website I'm developing. After a bit of digging I discovered that this occurs when the length of certain aspects of the URL exceed configurable limits in IIS7. In this case the maxQueryString attribute of the requestLimits property needed to be increased in the web.config <system.webServer> <security> <requestFiltering> <requestLimits maxQueryString="4096" maxAllowedContentLength="4096" maxUrl="8192" > </requestLimits> </requestFiltering> </security> This fixed the problem instantly on my development server but on the remote server I now get: 500 - Internal server error. There is a problem with the resource you are looking for, and it cannot be displayed. And that's all the information it gives me.

• Multi-Threading - Cleanup strategy at program end

  - by weismat

  What is the best way to finish a multi-threaded application in a clean way? I am starting several socket connections from the main thread in seperate sockets and wait until the end of my business day in the main thread and use currently System.Environment.Exit(0) to terminate it. This leads to an unhandled execption in one of the childs. Should I stop the threads from the list? I have been reluctant to implement any real stopping in the childs yet, thus I am wondering about the best practice. The sockets are all wrapped nicely with proper destructors for logging out and closing, but it still leads to errors.

• Connecting to multiple firebird Databases via Delphi

  - by Branden

  I am integrating a system with 2 other applications, 1 using a Firebird database whilst the other BIS (using ADO). My delphi application uses Firebird. I need to read data from my database, insert it into both the BIS database and the other application firebird database. I have created seperate data modules for each. Sending data to the ADO works fine, but when writing to the other Firebird DB (my db still open) I get strange errors. I have managed to isolate the problem to the second firebird DB. Small data writes seems fine. The data structures are completly different, so un able to use a synch tool. is there a way to overcome this by using multi threading or seperate memory space each Firebird instance uses?
