  I wrote a simple javascript function for validating to fields in a aspx page function validate() { if (document.getElementById("<%=tbName.ClientID%>").value=="") { alert("Name Feild can not be blank"); document.getElementById("<%=tbName.ClientID%>").focus(); return false; } if (document.getElementById("<%=ddlBranch.ClientID%>").value=="SelectBranch") { alert("Branch Should Be Selected"); document.getElementById("<%=ddlBranch.ClientID%>").focus(); return false; } } Everything worked fine. Later I linked it to aspx page like a external js file. Now its giving error "Microsoft JScript runtime error: Object required". I'm unable to know where I went wrong.

• What CPAN module can summarize Perl error logs?

  - by mithaldu

  I'm maintaining some website code that will soon dump all its errors and warnings into a log file. In order to make this a bit more pro-active I plan to parse this log file daily, summarize the warnings and errors (i.e. count the occurrence of each specific one and group by either warning/error) and then email this to the devs on the project. This would likely admittedly be rather trivial with a hash and some further fiddling, I wondered if there is a suitable module on CPAN that I could use to do this task. It would either be one that summarizes specifically Perl error/warnings logs or one that summarizes arbitrary text files. Any suggestions?

• sql and pooled connection error

  - by user319075

  Dear all, Kindly look at the following code as this sample code gives an error when i hosted it on Hostexcellence , but locally it runs perfect, and the error is as the following: Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached SqlDataSource1.SelectCommand = "Select Top (3) * from News Order by NewsID Desc"; SqlDataSource1.DataSourceMode = SqlDataSourceMode.DataReader; SqlDataReader r_News = (SqlDataReader)SqlDataSource1.Select(DataSourceSelectArguments.Empty); DataGrid_News.DataSource = r_News; r_News.Close(); DataGrid_News.DataBind(); So What's wrong with that code ??

• "No architectures" error when compiling objective flickr for iphone device

  - by user176723

  I'm getting the following error when I attempt to compile my XCode project to debug on my device. No architectures to compile for (ARCHS=x86_64, VALID_ARCHS=armv6 armv7). I've included ObjectiveFlickr in my project just as the readme describes. I've gone through the process several times and redownloaded objectiveFlickr a few times to start over. I've gotten objectiveFlickr to work on devices in the past. I don't know why I am suddenly having trouble. Can anybody point me to something that might hold the clue I need? Any other info I need to provide? I made only changes to my project that are specified by the OF documentation. I also get this error when compiling the included snap-n-run example project provided with OF. So I must be missing something beneath my project. Thanks, Charlie

• .Net Designer assemblies, C++\C# error

  - by greggorob64

  I'm working on an designer-heavy application (using Visual C++ 2.0, but a C# solution should still be relevant). My setup is this: I have a UserControl named "Host" I'm attempting a UserControl named "Child" Child contains a property to a class whose type is defined in a different dll entirely, named "mytools.dll" Child works just fine in the designer. However, when I go to drag "child" onto "host" from the designer, I get the following error: Failed to create component 'Child'. The error message follows: 'System.io.filenotfoundexception: could not load file or assembly MyTools, Version XXXXXX, Culture=neutral ..... {unhelpful callstack} If I comment out the property in "child" that points to the class in mytools.dll, everything designs just peachy. I have the property marked with "Browsable(false), and DesignerSerializable(hidden), and it does not help. Is there a way for me to explicitly say "Don't load this dll, you won't need it in design time", or some way for me to force a dll to load from the designer programmatically? Thanks!

• PHP: System Timezone Setting error

  - by marknt15

  Hi, I'm trying to use PHP in the terminal under MAMP but I got an error related to the system's timezone settings. How can I fix this error? $/Applications/MAMP/bin/php5/bin/php echo.php PHP Strict Standards: PHP Startup: It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Asia/Manila' for 'PHT/8.0/no DST' instead in Unknown on line 0 Thanks

• Foolproof way to check for nonzero (error) return code in windows batch file

  - by Pat

  Intro There's a lot of advice out there for dealing with return codes in batch files (using the ERROLEVEL mechanism), e.g. Get error code from within a batch file ERRORLEVEL inside IF Some of the advice is to do if errorlevel 1 goto somethingbad, while others recommend using the %ERRORLEVEL% variable and using ==, EQU, LSS, etc. There seem to be issues within IF statements and such, so then delayedexpansion is encouraged, but it seems to come with quirks of its own. Question What is a foolproof (i.e. robust, so it will work on nearly any system with nearly any return code) way to know if a bad (nonzero) code has been returned? My attempt For basic usage, the following seems to work ok to catch any nonzero return code: if not errorlevel 0 ( echo error level was nonzero )

• C2360 compiler error on TFS build, but not on desktop

  - by pdmaguire

  A c++ code snippet similar to the code below caused our TFS build to fail with a C2360 compiler error. switch (i) { case 0 : for each (int n in a) System::Console::WriteLine(n.ToString()); break; case 1 : System::Console::WriteLine("n is not in scope here"); break; } This is fixed by using {} brackets within the body of case 0, as below: switch (i) { case 0 : { for each (int n in a) System::Console::WriteLine(n.ToString()); } break; case 1 : System::Console::WriteLine("n is not in scope here"); break; } The developer had successfully compiled the code on their desktop before committing the changes. A cursory look at versions of things like compilers, Visual Studio etc on the server and desktop suggest they are the same. The source code is the same, obviously. What is the difference between a desktop build and TFS build that would smother a compiler error like this?

• Windows Phone 7 HttpRequest Unable to see true Error Code and response details

  - by Bob

  I have to call a somewhat broken API from a Windows Phone 7 application. The API returns a 302 error and a cookie to the authentication request. I've tried every way I've been able to find in the MSDN documentation for using ClientHTTP instead of BrowserHTTP (registering the prefix, using the call to explicitly create a ClientHTTP using Request), but the 302 is getting translated to a 404 and I'm not seeing the cookies on the response. I've tried a WebClient, I've tried an HttpRequest and it is always the translated error message. If I allocate a CookieContainer for the HttpRequest, I get a null argument exception when the client stack is parsing the returned message. I can see that the response is coming back as expected via Fiddler.
