• Passing $_GET or $_POST data to PHP script that is run with wget

  - by Matt

  Hello, I have the following line of PHP code which works great: exec( 'wget http://www.mydomain.com/u1.php /dev/null &' ); u1.php acts to do various types of maintenance on my server and the above command makes it happen in the background. No problems there. But I need to pass variable data to u1.php before it's executed. I'd like to pass POST data preferably, but could accommodate GET or SESSION data if POST isn't an option. Basically the type of data being passed is user-specific and will vary depending on who is logged in to the site and triggering the above code. I've tried adding the GET data to the end of the URL and that didn't work. So how else might I be able to send the data to u1.php? POST data preferred, SESSION data would work as well (but I tried this and it didn't pick up the logged in user's session data). GET would be a last resort. Thanks!

• A better solution than element.Elements("Whatever").First()?

  - by codeka

  I have an XML file like this: <SiteConfig> <Sites> <Site Identifier="a" /> <Site Identifier="b" /> <Site Identifier="c" /> </Sites> </SiteConfig> The file is user-editable, so I want to provide reasonable error message in case I can't properly parse it. I could probably write a .xsd for it, but that seems kind of overkill for a simple file. So anyway, when querying for the list of <Site> nodes, there's a couple of ways I could do it: var doc = XDocument.Load(...); var siteNodes = from siteNode in doc.Element("SiteConfig").Element("SiteUrls").Elements("Sites") select siteNode; But the problem with this is that if the user has not included the <SiteUrls> node (say) it'll just throw a NullReferenceException which doesn't really say much to the user about what actually went wrong. Another possibility is just to use Elements() everywhere instead of Element(), but that doesn't always work out when coupled with calls to Attribute(), for example, in the following situation: var siteNodes = from siteNode in doc.Elements("SiteConfig") .Elements("SiteUrls") .Elements("Sites") where siteNode.Attribute("Identifier").Value == "a" select siteNode; (That is, there's no equivalent to Attributes("xxx").Value) Is there something built-in to the framework to handle this situation a little better? What I would prefer is a version of Element() (and of Attribute() while we're at it) that throws a descriptive exception (e.g. "Looking for element <xyz> under <abc> but no such element was found") instead of returning null. I could write my own version of Element() and Attribute() but it just seems to me like this is such a common scenario that I must be missing something...

• Using parameterized function calls in SELECT statements. MS SQL Server

  - by geekzlla

  I have taken over some code from a previous developer and have come across this SQL statement that calls several SQL functions. As you can see, the function calls in the select statement pass a parameter to the function. How does the SQL statement know what value to replace the variable with? For the below sample, how does the query engine know what to replace nDeptID with when it calls, fn_SelDeptName_DeptID(nDeptID)? nDeptID IS a column in table Note. SELECT STATEMENT: SELECT nCustomerID AS [Customer ID], nJobID AS [Job ID], dbo.fn_SelDeptName_DeptID(nDeptID) AS Department, nJobTaskID AS JobTaskID, dbo.fn_SelDeptTaskDesc_OpenTask(nJobID, nJobTaskID) AS Task, nStandardNoteID AS StandardNoteID, dbo.fn_SelNoteTypeDesc(nNoteID) AS [Note Type], dbo.fn_SelGPAStandardNote(nStandardNoteID) AS [Standard Note], nEntryDate AS [Entry Date], nUserName as [Added By], nType AS Type, nNote AS Note FROM Note WHERE nJobID = 844261 xORDER BY nJobID, Task, [Entry Date] ====================== Function fn_SelDeptName_DeptID: ALTER FUNCTION [dbo].[fn_SelDeptName_DeptID] (@iDeptID int) RETURNS varchar(25) -- Used by DataCollection for Job Tracking -- if the Deptartment isnt found return an empty string BEGIN -- Return the Department name for the given DeptID. DECLARE @strDeptName varchar(25) IF @iDeptID = 0 SET @strDeptName = '' ELSE BEGIN SET @strDeptName = (SELECT dName FROM Department WHERE dDeptID = @iDeptID) IF (@strDeptName IS NULL) SET @strDeptName = '' END RETURN @strDeptName END ========================== Thanks in advance.

• Undefined test not working in javascript.

  - by James South

  I'm getting the error 'foo' is undefined. in my script when i test my function with an undefined parameter. As far as I understand, This shouldn't be happening. My calling code: //var foo var test = peachUI().stringIsNullOrEmpty(foo) ; My function (part of a larger framework). stringIsNullOrEmpty: function (testString) { /// <summary> /// Checks to see if a given string is null or empty. /// </summary> /// <param name="testString" type="String"> /// The string check against. /// </param> /// <returns type="Boolean" /> var $empty = true; if (typeof testString !== "undefined") { if (testString && typeof testString === "string") { if (testString.length > 0) { $empty = false; } } } return $empty; } Any ideas? Please note. I've had a good read of other similar questions before posting this one.

• How can i initialise a server on startup?

  - by djerry

  Hey all, I need to make some connections on startup of a server. I'm using the wcf technology for this client-server application. The problem is that the constructor of the server isn't called at any time, so for the moment, i initialize the connections when the first client makes a connection. But this generates problems in a further part. This is my server setup: private static ServiceHost _svc; static void Main(string[] args) { NetTcpBinding binding = new NetTcpBinding(SecurityMode.Message); Uri address = new Uri("net.tcp://localhost:8000"); _svc = new ServiceHost(typeof(MonitoringSystemService), address); publishMetaData(_svc, "http://localhost:8001"); _svc.AddServiceEndpoint(typeof(IMonitoringSystemService), binding, "Monitoring Server"); _svc.Open(); Console.WriteLine("Listener service gestart op net.tcp://localhost:8000/Monitoring"); Console.ReadLine(); } private static void publishMetaData(ServiceHost svc, string sEndpointAddress) { ServiceMetadataBehavior smb = svc.Description.Behaviors.Find<ServiceMetadataBehavior>(); if (smb != null) { smb.HttpGetEnabled = true; smb.HttpGetUrl = new Uri(sEndpointAddress); } else { smb = new ServiceMetadataBehavior(); smb.HttpGetEnabled = true; smb.HttpGetUrl = new Uri(sEndpointAddress); svc.Description.Behaviors.Add(smb); } } How can i start the server without waiting for a client to logon so i can initialize it. Thanks in advance.

• WCF operationcontract with List type unavailable in (Silverlight) client

  - by Dave

  This is the first time I have tried returning a List of data to a Silverlight client, so I'm having trouble getting the client to recognize this operationcontract. All others are fine. I have a method on the server called ReadOwFileData that needs to return a List. ReadOwFileDataCompletedEventArgs shows up in the Object Browser in the client, but not ReadOwFileDataAsync. What I want is similar to the tutorial here. The Dictionary collection type on the client is set to System.Collections.Generic.List. I tried deleting and recreating the service reference. Web.Config on the server is using basicHttpBinding. Here is the operationcontract on the server: [OperationContract] public List<OwFileData> ReadOwFileData(string OrderID) { DataClasses1DataContext db = new DataClasses1DataContext(); var dFileData = (from p in db.OwFileDatas where p.OrderID == OrderID select p).ToList(); List<OwFileData> x = new List<OwFileData>(dFileData); return x; } Incidently, this works fine: [OperationContract] public Customer GetShippingAndContactInfo(string login, string ordernum) { DataClasses1DataContext db = new DataClasses1DataContext(); Customer dInfo = (from p in db.Customers where p.Login == login select p).Single(); return dInfo; } I would like to read this data in the client and place it into an object I created called ObservableCollection. But that obviously can't happen until the client can see the method on the server. I do not know if this is an acceptable start, but this is what is on the client so far. The ReadOwFileDataAsync object is null: void populatefilesReceivedDataSource(string OrderID) { ArtUpload.ServiceReference1.UploadServiceClient client = new ArtUpload.ServiceReference1.UploadServiceClient(); var myList = client.ReadOwFileDataAsync(OrderID); // can I just itterate thru the list instead of 'binding' }

• Problem reading in file written with xdr using c

  - by Inga

  I am using Ubuntu 10.4 and have two (long) C programs, one that writes a file using XDR, and one that uses this file as input. However, the second program does not manage to read in the written file. Everything looks perfectly fine, it just does not work. More spesifically it fails at the last line added here with the error message xdr_string(), which indicates that it can not read in the first line of the input file. I do no see any obvious errors. The input file is written out, have a content and I can see the right strings using stings -a -n 2 "inputfile". Anyone have any idea what is going wrong? Relevant parts of program 1 (writer): /** * create compressed XDR output stream */ output_file=open_write_pipe(output_filename); xdrstdio_create(&xdrs, output_file, XDR_ENCODE); /** * print material name */ if( xdr_string(&xdrs, &name, _POSIX_NAME_MAX) == FALSE ) xdr_err("xdr_string()"); Relevant parts of program 2 (reader): /** * open data file */ input_file=open_data_file(input_filename, "r"); if( input_file == NULL ){ ERROR(input_filename); exit(EXIT_FAILURE); } /** * create input XDR stream */ xdrstdio_create(&xdrs, input_file, XDR_DECODE); /** * read material name */ if(xdr_string(&xdrs, &name, _POSIX_NAME_MAX) == FALSE) XDR_ERR("xdr_string()");

• Split a Large File In C++

  - by wdow88

  Hey all, I'm trying to write a program that takes a large file (of any time) and splits it into many smaller "chunks". I think I have the basic idea down, but for some reason I cannot create a chunk size over 12,000 bites. I know there are a few solutions on google, etc. but I am more interested in learning what the origin of this limitation is then actually using the program to split files. //This file splits are larger into smaller files of a user inputted size. #include<iostream> #include<fstream> #include<string> #include<sstream> #include <direct.h> #include <stdlib.h> using namespace std; void GetCurrentPath(char* buffer) { _getcwd(buffer, _MAX_PATH); } int main() { // use the function to get the path char CurrentPath[_MAX_PATH]; GetCurrentPath(CurrentPath);//Get the current directory (used for displaying output) fstream bigFile; string filename; int partsize; cout << "Enter a file name: "; cin >> filename; //Recieve target file cout << "Enter the number of bites in each smaller file: "; cin >> partsize; //Recieve volume size bigFile.open(filename.c_str(),ios::in | ios::binary); bigFile.seekg(0, ios::end); // position get-ptr 0 bytes from end int size = bigFile.tellg(); // get-ptr position is now same as file size bigFile.seekg(0, ios::beg); // position get-ptr 0 bytes from beginning for (int i = 0; i <= (size / partsize); i++) { //Build File Name string partname = filename; //The original filename string charnum; //archive number stringstream out; //stringstream object out, used to build the archive name out << "." << i; charnum = out.str(); partname.append(charnum); //put the part name together //Write new file part fstream filePart; filePart.open(partname.c_str(),ios::out | ios::binary); //Open new file with the name built above //Check if near the end of file if (bigFile.tellg() < (size - (size%partsize))) { filePart.write(reinterpret_cast<char *>(&bigFile),partsize); //Write the selected amount to the file filePart.close(); //close file bigFile.seekg(partsize, ios::cur); //move pointer to next position to be written } //Changes the size of the last volume because it is the end of the file else { filePart.write(reinterpret_cast<char *>(&bigFile),(size%partsize)); //Write the selected amount to the file filePart.close(); //close file } cout << "File " << CurrentPath << partname << " produced" << endl; //display the progress of the split } bigFile.close(); cout << "Split Complete." << endl; return 0; } Any ideas? Thanks!

• Extended Zend_Db_Table_Row_Abstract does not return values

  - by WesleyE

  Hi, I'm quite new to Zend and the database classes from it. I'm having problems mapping a Zend_Db_Table_Row_Abstract to my rows. The problem is that whenever I try to map it to a class (Job) that extends the Zend_Db_Table_Row_Abstract class, the database data is not receivable anymore. I'm not getting any errors, trying to get data simply returns null. Here is my code so far: Jobs: class Jobs extends Zend_Db_Table_Abstract { protected $_name = 'jobs'; protected $_rowsetClass = "Job"; public function getActiveJobs() { $select = $this->select()->where('jobs.jobDateOpen < UNIX_TIMESTAMP()')->limit(15,0); $rows = $this->fetchAll($select); return $rows; } } Job: class Job extends Zend_Db_Table_Row_Abstract { public function getCompanyName() { //Gets the companyName for this row (Is on another table), just for example } } Controller: $oJobs = new Jobs(); $aActiveJobs = $oJobs->getActiveJobs(); foreach ($aActiveJobs as $value) { var_dump($value->jobTitle); } When I remove the "protected $_rowsetClass = "Job";" line, so that the table row is not mapped to my own class, I get all the jobTitles perfectly. What am I doing wrong here? Thanks in advance, Wesley

• How do I call a variable from another class?

  - by squeezemylime

  I have a class called 'Constants' that I am storing a String variable in. This class contains a few global variables used in my app. I want to be able to reference this class and call the variable (called profileId) in other Views of my app. I looked around and found a few examples, but am not sure how to do this. Currently my setup is: Constants.h @interface Constants : UIViewController { NSString *profileId; } @property (nonatomic, retain) NSString *profileId; @end Constants.m #import "Constants.h" @implementation Constants @synthesize profileId; - (void)dealloc { [profileId release]; [super dealloc]; } And I am trying to call the variable profileId in a new View via this way: NewView.h file @class Constants; NewView.m file NSLog(@"ProfileId is:", [myConstants profileId]); Is there something I'm missing? It is coming up null, even though I am properly storing a value in it in another function via this way: Constants *Constant; Constant = [[Constants alloc] init]; Constant.profileId = userId;

• BlackBerry 5.0 causing full menu to show on navigationClick

  - by jwadsack

  I have a BlackBerry app that is built for 4.5.x SDK. The first page of the app shows a list of fields and each field can be highlighted and clicked. The click action shows a new view with additional information about the field. This all works fine in 4.5, 4.6 and 4.7 and on the sim with 5.0. On a real 9000 running 5.0, when clicking the trackball on an item in the list, the full menu is showing rather than the click event getting consumed (or even fired) for the field. The view is derived from MainScreen and looks something like this: public class ListView extends MainScreen { public ItemCollection list = new ItemCollection; protected void sublayout( int maxWidth, int maxHeight ) { int i = 1; while(( item == (Item)list.nextElement()) != null) { ItemField field = new ItemField(item, i++); add(field); } } } This class does not consume navigationClick, but shouldn't need to, right? The field class does consume navigationClick event: public class ItemField extends Field { protected boolean navigationClick(int status, int time) { controller.showDeal(item.id, Session.current); return true; } } Is there something that changed in 5.0 that I need to add to have this app work the same for all platforms?

• JSF getter methods called BEFORE beforePhase fires

  - by Bill Leeper

  I got a recommendation to put all data lookups in the beforePhase for a given page, however, now that I am doing some deeper analysis it appears that some getter methods are being called before the beforePhase is fired. It became very obvious when I added support for a url parameter and I was getting NPEs on objects that are initialized in the beforePhase call. Any thoughts? Something I have set wrong. I have this in my JSP page: <f:view beforePhase="#{someController.beforePhaseSummary}"> That is only the 5th line in the JSP file and is right after the taglibs. Here is the code that is in the beforePhaseSummary method: public void beforePhaseSummary(PhaseEvent event) { logger.debug("Fired Before Phase Summary: " + event.getPhaseId()); if (event.getPhaseId() == PhaseId.RENDER_RESPONSE) { HttpServletRequest request = (HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest(); if (request.getParameter("application_id") != null) { loadApplication(Long.parseLong(request.getParameter("application_id"))); } /* Do data fetches here */ } } The logging output above indicates that an event is fired. The servlet request is used to capture the url parameters. The data fetches gather data. However, the logging output is below: 2010-04-23 13:44:46,968 [http-8080-4] DEBUG ...SomeController 61 - Get Permit 2010-04-23 13:44:46,968 [http-8080-4] DEBUG ...SomeController 107 - Getting UnsubmittedCount 2010-04-23 13:44:46,984 [http-8080-4] DEBUG ...SomeController 61 - Get Permit 2010-04-23 13:44:47,031 [http-8080-4] DEBUG ...SomeController 133 - Fired Before Phase Summary: RENDER_RESPONSE(6) The logs indicate 2 calls to the getPermit method and one to getUnsubmittedCount before the beforePhase is fired.

  i have an asp.net website where i need to use URL re-write so i have written an HTTP module and i have implemented it and it works correctly the only problem is when the page redirect to its corresponding address the images and the styles are not loaded. here is the http module: // Your BeginRequest event handler. private void Application_BeginRequest(Object source, EventArgs e) { HttpApplication application = (HttpApplication)source; string URL = application.Request.Url.ToString(); //int pid = Convert.ToInt32(application.Request.QueryString["pid"]); if ((URL.ToLower().Contains(".aspx")) || (URL.ToLower().Contains(".js")) || (URL.ToLower().Contains(".css")) || (URL.ToLower().Contains(".gif")) || (URL.ToLower().Contains(".png")) || (URL.ToLower().Contains(".jpeg")) || (URL.ToLower().Contains(".jpe")) || (URL.ToLower().Contains(".jpg")) || (URL.ToLower().Contains(".ashx"))) return; else { string mname = URL.Substring(URL.LastIndexOf("/") + 1).ToString(); Merchand ms = merchantDB.GetMerchant(mname); HttpContext context = application.Context; if (ms != null) { string url = "~/pages/Merchant.aspx?mid=" + ms.MerchandID + "&catid=" + ms.MainCategory + "&subcatid=0"; context.RewritePath(VirtualPathUtility.ToAppRelative(url)); } else { //(""); string url = "~/pages/default.aspx"; context.RewritePath(VirtualPathUtility.ToAppRelative(url)); } } } when i open the page from it normal URL it opens fine, but when i use the url rewrite it open but with out images or styles. when i open firebug i get an error that the css and the javascript are not found

• Can you explain this generics behavior and if I have a workaround?

  - by insta

  Sample program below: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace GenericsTest { class Program { static void Main(string[] args) { IRetrievable<int, User> repo = new FakeRepository(); Console.WriteLine(repo.Retrieve(35)); } } class User { public int Id { get; set; } public string Name { get; set; } } class FakeRepository : BaseRepository<User>, ICreatable<User>, IDeletable<User>, IRetrievable<int, User> { // why do I have to implement this here, instead of letting the // TKey generics implementation in the baseclass handle it? //public User Retrieve(int input) //{ // throw new NotImplementedException(); //} } class BaseRepository<TPoco> where TPoco : class,new() { public virtual TPoco Create() { return new TPoco(); } public virtual bool Delete(TPoco item) { return true; } public virtual TPoco Retrieve<TKey>(TKey input) { return null; } } interface ICreatable<TPoco> { TPoco Create(); } interface IDeletable<TPoco> { bool Delete(TPoco item); } interface IRetrievable<TKey, TPoco> { TPoco Retrieve(TKey input); } } This sample program represents the interfaces my actual program uses, and demonstrates the problem I'm having (commented out in FakeRepository). I would like for this method call to be generically handled by the base class (which in my real example is able to handle 95% of the cases given to it), allowing for overrides in the child classes by specifying the type of TKey explicitly. It doesn't seem to matter what parameter constraints I use for the IRetrievable, I can never get the method call to fall through to the base class. Also, if anyone can see an alternate way to implement this kind of behavior and get the result I'm ultimately looking for, I would be very interested to see it. Thoughts?

• Difference dynami static 2d array c++

  - by snorlaks

  Hello, Im using opensource library called wxFreeChart to draw some XY charts. In example there is code which uses static array as a serie : double data1[][2] = { { 10, 20, }, { 13, 16, }, { 7, 30, }, { 15, 34, }, { 25, 4, }, }; dataset-AddSerie((double *) data1, WXSIZEOF(dynamicArray)); WXSIZEOF ismacro defined like: sizeof(array)/sizeof(array[0]) In this case everything works great but in my program Im using dynamic arrays (according to users input). I made a test and wrotecode like below: double **dynamicArray = NULL; dynamicArray = new double *[5] ; for( int i = 0 ; i < 5 ; i++ ) dynamicArray[i] = new double[2]; dynamicArray [0][0] = 10; dynamicArray [0][1] = 20; dynamicArray [1][0] = 13; dynamicArray [1][1] = 16; dynamicArray [2][0] = 7; dynamicArray [2][1] = 30; dynamicArray [3][0] = 15; dynamicArray [3][1] = 34; dynamicArray [4][0] = 25; dynamicArray [4][1] = 4; dataset-AddSerie((double *) *dynamicArray, WXSIZEOF(dynamicArray)); But it doesnt work correctly. I mean point arent drawn. I wonder if there is any possibility that I can "cheat" that method and give it dynamic array in way it understands it and will read data from correct place thanks for help

• Java JNI leak in c++ process.

  - by user662056

  Hi all.. I am beginner in Java. My problem is: I am calling a Java class's method from c++. For this i am using JNI. Everythings works correct, but i have some memory LEAKS in the process of c++ program... So.. i did simple example.. 1) I create a java machine (jint res = JNI_CreateJavaVM(&jvm, (void**)&env, &vm_args);) 2) then i take a pointer on java class (jclass cls = env-FindClass("test_jni")); 3) after that i create a java class object object, by calling the constructor (testJavaObject = env-NewObject(cls, testConstruct);) AT THIS very moment in the process of c++ program is allocated 10 MB of memory 4) Next i delete the class , the object, and the Java Machine .. AT THIS very moment the 10 MB of memory are not free ................. So below i have a few lines of code c++ program void main() { { //Env JNIEnv *env; // java virtual machine JavaVM *jvm; JavaVMOption* options = new JavaVMOption[1]; //class paths options[0].optionString = "-Djava.class.path=C:/Sun/SDK/jdk/lib;D:/jms_test/java_jni_leak;"; // other options JavaVMInitArgs vm_args; vm_args.version = JNI_VERSION_1_6; vm_args.options = options; vm_args.nOptions = 1; vm_args.ignoreUnrecognized = false; // alloc part of memory (for test) before CreateJavaVM char* testMem0 = new char[1000]; for(int i = 0; i < 1000; ++i) testMem0[i] = 'a'; // create java VM jint res = JNI_CreateJavaVM(&jvm, (void**)&env, &vm_args); // alloc part of memory (for test) after CreateJavaVM char* testMem1 = new char[1000]; for(int i = 0; i < 1000; ++i) testMem1[i] = 'b'; //Creating java virtual machine jclass cls = env->FindClass("test_jni"); // Id of a class constructor jmethodID testConstruct = env->GetMethodID(cls, "<init>", "()V"); // The Java Object // Calling the constructor, is allocated 10 MB of memory in c++ process jobject testJavaObject = env->NewObject(cls, testConstruct); // function DeleteLocalRef, // In this very moment memory not free env->DeleteLocalRef(testJavaObject); env->DeleteLocalRef(cls); // 1!!!!!!!!!!!!! res = jvm->DestroyJavaVM(); delete[] testMem0; delete[] testMem1; // In this very moment memory not free. TO /// } int gg = 0; } java class (it just allocs some memory) import java.util.*; public class test_jni { ArrayList<String> testStringList; test_jni() { System.out.println("start constructor"); testStringList = new ArrayList<String>(); for(int i = 0; i < 1000000; ++i) { // ??????? ?????? testStringList.add("TEEEEEEEEEEEEEEEEST"); } } } process memory view, after crating javaVM and java object: testMem0 and testMem1 - test memory, that's allocated by c++. ************** testMem0 ************** JNI_CreateJavaVM ************** testMem1 ************** // create java object jobject testJavaObject = env->NewObject(cls, testConstruct); ************** process memory view, after destroy javaVM and delete ref on java object: testMem0 and testMem1 are deleted to; ************** JNI_CreateJavaVM ************** // create java object jobject testJavaObject = env->NewObject(cls, testConstruct); ************** So testMem0 and testMem1 is deleted, But JavaVM and Java object not.... Sow what i do wrong... and how i can free memory in the c++ process program.

• javascript style.visibility doesn't seem to work....

  - by Pandiya Chendur

  In my aspx page i have a tr which is set visible="false" by default... But on a selected index of a dropdown i make it visible="true" ..... On the form submit i am validating the control within the tr but couldn't find whether the tr is visinle or not using javascript... My aspx: <tr id="MeasurementTr" runat="server" visible="false"> <td> &nbsp;</td> <td class="table_label"> Measurement</td> <td> &nbsp;</td> <td> <asp:DropDownList ID="DlMeasurement" runat="server"> </asp:DropDownList> </td> <td> &nbsp;</td> </tr> and my javascript, alert(document.getElementById("ctl00_ContentPlaceHolder1_MeasurementTr").style.visibility); if (document.getElementById("ctl00_ContentPlaceHolder1_MeasurementTr").style.visibility=="visible"){ if (document.getElementById("ctl00_ContentPlaceHolder1_DlMeasurement").selectedIndex == 0) { document.getElementById("ctl00_ContentPlaceHolder1_ErrorMsg").innerHTML = "Please Select Your Measurement"; document.getElementById("ctl00_ContentPlaceHolder1_DlMeasurement").focus(); return false; } } But my alert shows nothing... It didnt show null or undefined...
