  • XPath find element based on ancestor element

    - by martymcfly
    Hi, again I have Java AST which is created from public class Test { String o = new String("hh"); public void wrong1() { synchronized(o) { // huhu } } } I try to create a XPath query which finds the synchronized block in which the defined String variable o is used. As the definition is above it is an ancestor of the SynchronizedStatement, but I dont get it working //SynchronizedStatement[Expression/PrimaryExpression/PrimaryPrefix/Name[@Image=ancestor::ClassOrInterfaceBody[ClassOrInterfaceBodyDeclaration/FieldVariableDeclaratorId/@Image]]] I know that /SynchronizedStatement[Expression/PrimaryExpression/PrimaryPrefix/Name[@Image= is correct, my problem is how to address the ancestor ClassOrInterfaceBody part. Hope its clear what i mean ;-) Thanks

  • Excel VBA SQL Import

    - by user307655
    Hi All, I have the following code which imports data from a spreadsheet to SQL directly from Excel VBA. The code works great. However I am wondering if somebody can help me modify the code to: 1) Check if data from column A already exists in the SQL Table 2) If exists, then only update rather than import as a new role 3) if does not exist then import as a new role.

  • DataTable to JSON

    - by Joel Coehoorn
    I recently needed to serialize a datatable to JSON. Where I'm at we're still on .Net 2.0, so I can't use the JSON serializer in .Net 3.5. I figured this must have been done before, so I went looking online and found a number of different options. Some of them depend on an additional library, which I would have a hard time pushing through here. Others require first converting to List<Dictionary<>>, which seemed a little awkward and needless. Another treated all values like a string. For one reason or another I couldn't really get behind any of them, so I decided to roll my own, which is posted below. As you can see from reading the //TODO comments, it's incomplete in a few places. This code is already in production here, so it does "work" in the basic sense. The places where it's incomplete are places where we know our production data won't currently hit it (no timespans or byte arrays in the db). The reason I'm posting here is that I feel like this can be a little better, and I'd like help finishing and improving this code. Any input welcome. public static class JSONHelper { public static string FromDataTable(DataTable dt) { string rowDelimiter = ""; StringBuilder result = new StringBuilder("["); foreach (DataRow row in dt.Rows) { result.Append(rowDelimiter); result.Append(FromDataRow(row)); rowDelimiter = ","; } result.Append("]"); return result.ToString(); } public static string FromDataRow(DataRow row) { DataColumnCollection cols = row.Table.Columns; string colDelimiter = ""; StringBuilder result = new StringBuilder("{"); for (int i = 0; i < cols.Count; i++) { // use index rather than foreach, so we can use the index for both the row and cols collection result.Append(colDelimiter).Append("\"") .Append(cols[i].ColumnName).Append("\":") .Append(JSONValueFromDataRowObject(row[i], cols[i].DataType)); colDelimiter = ","; } result.Append("}"); return result.ToString(); } // possible types: // http://msdn.microsoft.com/en-us/library/system.data.datacolumn.datatype(VS.80).aspx private static Type[] numeric = new Type[] {typeof(byte), typeof(decimal), typeof(double), typeof(Int16), typeof(Int32), typeof(SByte), typeof(Single), typeof(UInt16), typeof(UInt32), typeof(UInt64)}; // I don't want to rebuild this value for every date cell in the table private static long EpochTicks = new DateTime(1970, 1, 1).Ticks; private static string JSONValueFromDataRowObject(object value, Type DataType) { // null if (value == DBNull.Value) return "null"; // numeric if (Array.IndexOf(numeric, DataType) > -1) return value.ToString(); // TODO: eventually want to use a stricter format // boolean if (DataType == typeof(bool)) return ((bool)value) ?

  • How to access "Custom" or non-System TFS workitem fields using PowerShell?

    - by DaBozUK
    When using PowerShell to extract information from TFS, I find that I can get at the standard fields but not "Custom" fields. I'm not sure custom is the correct term, but for example if I look at the Process Editor in VS2008 and edit the Work Item type, there are fields such as listed below, with Name, Type and RefName: Title String System.Title State String System.State Rev Integer System.Rev Changed By String System.ChangedBy I can access these with Get-TfsItemHistory: Get-TfsItemHistory "$/path" -Version "D01/12/10~" -R | Select -exp WorkItems | Format-Table Title, State, Rev, ChangedBy -Auto So far so good. However, there are also some other fields in the WorkItem type, which I'm calling "Custom" or non-System fields, e.g.: Activated By String Microsoft.VSTS.Common.ActivatedBy Resolved By String Microsoft.VSTS.Common.ResolvedBy And the following command does not retrieve the data, just spaces. Get-TfsItemHistory "$/path" -Version "D01/12/10~" -R | Select -exp WorkItems | Format-Table ActivatedBy, ResolvedBy -Auto I've also tried the names in quotes, the fully qualified refname, but no luck. How do you access these "non-System" fields? Thanks Boz UPDATE: From Keith's answer I can get the fields I need: Get-TfsItemHistory "$/Hermes/Main" -Version "D01/12/10~" -Recurse ` | Select ChangeSetId, Comment -exp WorkItems ` | Select ChangeSetId, Comment, @{n='WI-Id'; e={$_.Id}}, Title -exp Fields ` | Where {$_.ReferenceName -eq 'Microsoft.VSTS.Common.ResolvedBy'} ` | Format-Table ChangesetId, Comment, WI-Id, Title, @{n='Resolved By'; e={$_.Value}} -Auto

  • ORGetValue from Offline Registry - ERROR_MORE_DATA

    - by user314749
    I am trying to create an offline registry in memory using the offreg.dll provided in the windows ddk 7 package. You can find out more information on the offreg.dll here: MSDN Currently, while attempting to read a value from an open registry hive / key I receive the following error: 234 or ERROR_MORE_DATA Here is the .h code that contains ORGetValue: DWORD ORAPI ORGetValue ( __in ORHKEY Handle, __in_opt PCWSTR lpSubKey, __in_opt PCWSTR lpValue, __out_opt PDWORD pdwType, __out_bcount_opt(*pcbData) PVOID pvData, __inout_opt PDWORD pcbData ); Here is the code that I am using to pull the data [DllImport("offreg.dll", CharSet = CharSet.Auto, EntryPoint = "ORGetValue", SetLastError = true, CallingConvention = CallingConvention.StdCall)] public static extern uint ORGetValue(IntPtr Handle, string lpSubKey, string lpValue, out uint pdwType, out string pvData, out uint pcbData); IntPtr myHive; IntPtr myKey; string myValue; uint pdwtype; uint pcbdata; uint ret3 = ORGetValue(myKey, "", "DefaultUserName", out pdwtype, out myValue, out pcbdata); The goal is to be able to read myValue as a string. I am not sure if I need to use marshaling... or a second call with an adjusted buffer.. Or really how to adjust the buffer in C#. Any help or pointers would be greatly appreciated. Thank you.

  • Why is my Map broken?

    - by Kirk
    Scenario: Creating a server which has Room objects which contain User objects. I want to store the rooms in a Map of some sort by Id (a string). Desired Behavior: When a user makes a request via the server, I should be able to look up the Room by id from the library and then add the user to the room, if that's what the request needs. Currently I use the static function in my Library.java class where the Map is stored to retrieve Rooms: public class Library { private static Hashtable<String, Rooms> myRooms = new Hashtable<String, Rooms>(); public static addRoom(String s, Room r) { myRooms.put(s, r); } public static Room getRoomById(String s) { return myRooms.get(s); } } In another class I'll do the equivalent of myRoom.addUser(user); What I'm observing using Hashtable, is that no matter how many times I add a user to the Room returned by getRoomById, the user is not in the room later. I thought that in Java, the object that was returned was essentially a reference to the data, the same object that was in the Hashtable with the same references; but, it isn't behaving like that. Is there a way to get this behavior? Maybe with a wrapper of some sort? Am I just using the wrong variant of map? Help?

  • operator<< cannot output std::endl -- Fix?

    - by dehmann
    The following code gives an error when it's supposed to output just std::endl: #include <iostream> #include <sstream> struct MyStream { std::ostream* out_; MyStream(std::ostream* out) : out_(out) {} std::ostream& operator<<(const std::string& s) { (*out_) << s; return *out_; } }; template<class OutputStream> struct Foo { OutputStream* out_; Foo(OutputStream* out) : out_(out) {} void test() { (*out_) << "OK" << std::endl; (*out_) << std::endl; // ERROR } }; int main(int argc, char** argv){ MyStream out(&std::cout); Foo<MyStream> foo(&out); foo.test(); return EXIT_SUCCESS; } The error is: stream1.cpp:19: error: no match for 'operator<<' in '*((Foo<MyStream>*)this)->Foo<MyStream>::out_ << std::endl' stream1.cpp:7: note: candidates are: std::ostream& MyStream::operator<<(const std::string&) So it can output a string (see line above the error), but not just the std::endl, presumably because std::endl is not a string, but the operator<< definition asks for a string. Templating the operator<< didn't help: template<class T> std::ostream& operator<<(const T& s) { ... } How can I make the code work? Thanks!

  • Using the Antenna and J2ME Polish preprocessors interchangeably and setting a variable value

    - by walter
    I have J2ME code, which I want to be able to compile using the J2ME Polish preprocessor or the wtkpreprocessor (antenna). They mostly use the same directives so it usually works, but ... When I want to insert an URL value in the Java code this gives a problem. In Antenna the code would look like this: //#ifdef my.url //# System.out.println("My Url"); //#expand String location = "%my.url%"; //#else System.out.println("Default"); String location = "http://www.some.default.url.com"; //#endif and in J2ME Polish it would look like this: //#ifdef my.url:defined //# System.out.println("My Url"); //#= String location = "${my.url}"; //#else System.out.println("Default"); String location = "http://www.some.default.url.com"; //#endif I want some way in which I can use the preprocessors interchangeably and still be able to set the url in the build.xml, any ideas?

  • call lynx from jsp script

    - by Piero
    Hi, I have an execute(String cmd) in a jsp script that calls the exec method from the Runtime class. It works when I call a local command, like a php script stored on the server. for example: /usr/bin/php /path/to/php/script arg1 arg2 So I guess my execute command is ok, since it is working with that. Now when I try to call lynx, the text-based web browser, it does not work. If I call it in a terminal, it works fine: /usr/bin/lynx -dump -accept_all_cookies 'http://www.someurl.net/?arg1=1&arg2=2' But when I call this from my execute command, nothing happens... Any idea why? This is my execute method: public String execute(String cmd){ Runtime r = Runtime.getRuntime(); Process p = null; String res = ""; try { p = r.exec(cmd); InputStreamReader isr = new InputStreamReader(p.getInputStream()); BufferedReader br = new BufferedReader(isr); String line = null; //out.println(res); while ((line = br.readLine()) != null) { res += line; } p.waitFor(); } catch (Exception e) { res += e; } System.out.println(p.exitValue()); return res; }

  • jQuery Ajax posting Arrays instead of simple data

    Hey, I've tried to update jQuery to its latest version on a system I'm working and I'm having this issue: I have a file that posts data to a .php: $.post( 'ajax_Save.php', { id: [$('#service_id').val()], number: [$('#number').val()] }, function(data){ ... }); On ajax_Save.php var_dump($_POST) gives: array(26) { ["id"]=> array(1) { [0]=> string(5) "18204" } ["number"]=> array(1) { [0]=> string(5) "18250" }... With jQuery version 1.2.2 the result is: array(26) { ["id"]=> string(5) "18204" ["order_number"]=> string(5) "18250" Which is OK. Any clues? Thx

  • CustomValidatation control that fire on multiple control events

    - by George
    I am trying to create a UserControl that is a composite control for entering Dates. It involves 2 drop down controls (one for month and one for day) and a text box for year. It also has a CustomValidation control that I would like the user of the UserControl to be able to set the ClientValidationFunction property and have it triggered whenever the value in any of the 3 date part controls changes. To hook up each of the 3 controls to the validation control, I use teh AJAX ValidatorHookupControlID method. If I hard code the following code directly in my aspx page that houses the usercontrol, my Client Validation Function is successfulluy called when any of the 3 date part control values are changed: <script type="text/javascript"> //<![CDATA[ debugger; alert('hooking up'); ValidatorHookupControlID("ctl00_phPageContent_dtmPassportExpirationDate_txtYear", document.all("ctl00_phPageContent_dtmPassportExpirationDate_CustomValidator1")); ValidatorHookupControlID("ctl00_phPageContent_dtmPassportExpirationDate_ddlDate", document.all("ctl00_phPageContent_dtmPassportExpirationDate_CustomValidator1")); ValidatorHookupControlID("ctl00_phPageContent_dtmPassportExpirationDate_ddlMonth", document.all("ctl00_phPageContent_dtmPassportExpirationDate_CustomValidator1")); //]]> However, I would like my usercontrol to emit this Javascript, so I added the following Code. Public Property ClientValidationFunction() As String Get Return CustomValidator1.ClientValidationFunction End Get Set(ByVal value As String) CustomValidator1.ClientValidationFunction = value End Set End Property Public Property EnableClientScript() As Boolean Get Return CustomValidator1.EnableClientScript End Get Set(ByVal value As Boolean) CustomValidator1.EnableClientScript = value End Set End Property Protected Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender If Me.ClientValidationFunction.Trim <> "" AndAlso Me.EnableClientScript Then RegisterValidationScript() End If End Sub Private Sub RegisterValidationScript() Dim Key As String = Me.ClientID & "_ClientValidate" If Not Page.ClientScript.IsClientScriptBlockRegistered(Key) Then Page.ClientScript.RegisterClientScriptBlock(GetType(String), Key, GetJavascript, True) End If End Sub Private Function GetJavascript() As String Dim Out As String = "" Const Quote As String = Chr(34) Out &= "debugger;" & vbCrLf Out &= "ValidatorHookupControlID(" & Quote & txtYear.ClientID & Quote & ", document.all(" & Quote & CustomValidator1.ClientID & Quote & "));" & vbCrLf Out &= "ValidatorHookupControlID(" & Quote & ddlDate.ClientID & Quote & ", document.all(" & Quote & CustomValidator1.ClientID & Quote & "));" & vbCrLf Out &= "ValidatorHookupControlID(" & Quote & ddlMonth.ClientID & Quote & ", document.all(" & Quote & CustomValidator1.ClientID & Quote & "));" & vbCrLf Return Out End Function Unfortunately, when the ValidatorHookupControlID method is called, the second parameter (the one that locates the validation control) always evaluates to null and the method fails. ValidatorHookupControlID("ctl00_phPageContent_DateSelector21_txtYear", document.all("ctl00_phPageContent_DateSelector21_CustomValidator1")); Can you tell me how to correct this error?
