  • Conversion failed when converting datetime from character string. Linq To SQL & OpenXML

    - by chobo2
    Hi I been following this tutorial on how to do a linq to sql batch insert. http://www.codeproject.com/KB/linq/BulkOperations_LinqToSQL.aspx However I have a datetime field in my database and I keep getting this error. System.Data.SqlClient.SqlException was unhandled Message="Conversion failed when converting datetime from character string." Source=".Net SqlClient Data Provider" ErrorCode=-2146232060 Class=16 LineNumber=7 Number=241 Procedure="spTEST_InsertXMLTEST_TEST" Server="" State=1 StackTrace: at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj) I am not sure why when I just take the datetime in the generated xml file and manually copy it into sql server 2005 it has no problem with it and converts it just fine. This is my SP CREATE PROCEDURE [dbo].[spTEST_InsertXMLTEST_TEST](@UpdatedProdData nText) AS DECLARE @hDoc int exec sp_xml_preparedocument @hDoc OUTPUT,@UpdatedProdData INSERT INTO UserTable(CreateDate) SELECT XMLProdTable.CreateDate FROM OPENXML(@hDoc, 'ArrayOfUserTable/UserTable', 2) WITH ( CreateDate datetime ) XMLProdTable EXEC sp_xml_removedocument @hDoc C# code using (TestDataContext db = new TestDataContext()) { UserTable[] testRecords = new UserTable[1]; for (int count = 0; count < 1; count++) { UserTable testRecord = new UserTable() { CreateDate = DateTime.Now }; testRecords[count] = testRecord; } StringBuilder sBuilder = new StringBuilder(); System.IO.StringWriter sWriter = new System.IO.StringWriter(sBuilder); XmlSerializer serializer = new XmlSerializer(typeof(UserTable[])); serializer.Serialize(sWriter, testRecords); db.spTEST_InsertXMLTEST_TEST(sBuilder.ToString()); } Rendered XML Doc <?xml version="1.0" encoding="utf-16"?> <ArrayOfUserTable xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <UserTable> <CreateDate>2010-05-19T19:35:54.9339251-07:00</CreateDate> </UserTable> </ArrayOfUserTable>

  • help in the Donalds B. Johnson's algorithm, i cannot understand the pseudo code

    - by Pitelk
    Hi , does anyone know the Donald B. Johnson's algorithm which enumarates all the elementary circuits (cycles) in a Directed graph? link text I have the paper he had published in 1975 but I cannot understand the pseudo-code. My goal is to implement this algorithm in java. Some questions i have is for example what is the matrix Ak it refers to. In the pseudo code mentions that Ak:=adjacency structure of strong component K with least vertex in subgraph of G induced by {s,s+1,....n}; Does that mean i have to implement another algorithm that finds the Ak matrix? Another question is what the following means? begin logical f; Does also the line "logical procedure CIRCUIT (integer value v);" means that the circuit procedure returns a logical variable. In the pseudo code also has the line "CIRCUIT := f;" . Does this mean? It would be great if someone could translate this 1970's pseudocode to a more modern type of pseudo code so i can understand it in case you are interested to help but you cannot find the paper please email me at [email protected] and i will send you the paper. Thanks in advance

  • Is there a workaround for JDBC w/liquibase and MySQL session variables & client side SQL instructions

    - by David
    Slowly building a starter changeSet xml file for one of three of my employer's primary schema's. The only show stopper has been incorporating the sizable library of MySQL stored procedures to be managed by liquibase. One sproc has been somewhat of a pain to deal with: The first few statements go like use TargetSchema; select "-- explanatory inline comment thats actually useful --" into vDummy; set @@session.sql_mode='TRADITIONAL' ; drop procedure if exists adm_delete_stats ; delimiter $$ create procedure adm_delete_stats( ...rest of sproc I cut out the use statement as its counter-productive, but real issue is the set @@session.sql_mode statement which causes an exception like liquibase.exception.MigrationFailedException: Migration failed for change set ./foobarSchema/sprocs/adm_delete_stats.xml::1293560556-151::dward_autogen dward: Reason: liquibase.exception.DatabaseException: Error executing SQL ... And then the delimiter statement is another stumbling block. Doing do dilligence research I found this rejected MySQL bug report here and this MySQL forum thread that goes a little bit more in depth to the problem here. Is there anyway I can use the sproc scripts that currently exist with Liquibase or would I have to re-write several hundred stored procedures? I've tried createProcedure, sqlFile, and sql liquibase tags without much luck as I think the core issue is that set, delimiter, and similar SQL commands are meant to be interpreted and acted upon by the client side interpreter before being delivered to the server.

  • Problem with date parameter - Oracle

    - by Nicole
    Hi everyone! I have this stored procedure: CREATE OR REPLACE PROCEDURE "LIQUIDACION_OBTENER" ( p_Cuenta IN NUMBER, p_Fecha IN DATE, p_Detalle OUT LIQUIDACION.FILADETALLE%TYPE ) IS BEGIN SELECT FILADETALLE INTO p_Detalle FROM Liquidacion WHERE (FILACUENTA = p_Cuenta) AND (FILAFECHA = p_Fecha); END; and my c# code: string liquidacion = string.Empty; OracleCommand command = new OracleCommand("Liquidacion_Obtener"); command.BindByName = true; command.Parameters.Add(new OracleParameter("p_Cuenta", OracleDbType.Int64)); command.Parameters["p_Cuenta"].Value = cuenta; command.Parameters.Add(new OracleParameter("p_Fecha", OracleDbType.Date)); command.Parameters["p_Fecha"].Value = fecha; command.Parameters.Add("p_Detalle", OracleDbType.Varchar2, ParameterDirection.Output); OracleConnectionHolder connection = null; connection = this.GetConnection(); command.Connection = connection.Connection; command.CommandTimeout = 30; command.CommandType = CommandType.StoredProcedure; OracleDataReader lector = command.ExecuteReader(); while (lector.Read()) { liquidacion += ((OracleString)command.Parameters["p_Detalle"].Value).Value; } the thing is that when I try to put a value into the parameter "Fecha" (that is a date) the code gives me this error (when the line command.ExecuteReader(); is executed) Oracle.DataAccess.Client.OracleException : ORA-06502: PL/SQL: numeric or value error ORA-06512: at "SYSTEM.LIQUIDACION_OBTENER", line 9 ORA-06512: at line 1 the thing is that te date in the data base is saved like a date but it's format is "2010-APR-14" and the value I send is a datetime that has this format: "14/04/2010 00:00:00" could it be that??? I hope my post is understandable.. thanks!!!!!!!!!!

  • delphi 2010 variant to unicode problem

    - by Crudler
    Please advise how I can achieve this. I am working in a dll in delphi 2010. This dll has a exported procedure that receives an array of variants. I want to be able to take one of these variants, and convert it into a string, but i keep getting ????? I cannot change the input variable - it HAS to be an array of variants. The host app that calls the dll cannot be changed. It is written in Delphi2006. sample dll's code is: Procedure TestArr(ArrUID : array of variant);stdcall; var i : integer; s:string; begin s:= string(String(Arruid[0])); showmessage(s); end; obviously in D2006 my dll works fine. I have tried using VartoStr - no luck. When I try test the VaType I am getting a varString Any suggestions?

  • Optimizing a lot of Scanner.findWithinHorizon(pattern, 0) calls

    - by darvids0n
    I'm building a process which extracts data from 6 csv-style files and two poorly laid out .txt reports and builds output CSVs, and I'm fully aware that there's going to be some overhead searching through all that whitespace thousands of times, but I never anticipated converting about about 50,000 records would take 12 hours. Excerpt of my manual matching code (I know it's horrible that I use lists of tokens like that, but it was the best thing I could think of): public static String lookup(List<String> tokensBefore, List<String> tokensAfter) { String result = null; while(_match(tokensBefore)) { // block until all input is read if(id.hasNext()) { result = id.next(); // capture the next token that matches if(_matchImmediate(tokensAfter)) // try to match tokensAfter to this result return result; } else return null; // end of file; no match } return null; // no matches } private static boolean _match(List<String> tokens) { return _match(tokens, true); } private static boolean _match(List<String> tokens, boolean block) { if(tokens != null && !tokens.isEmpty()) { if(id.findWithinHorizon(tokens.get(0), 0) == null) return false; for(int i = 1; i <= tokens.size(); i++) { if (i == tokens.size()) { // matches all tokens return true; } else if(id.hasNext() && !id.next().matches(tokens.get(i))) { break; // break to blocking behaviour } } } else { return true; // empty list always matches } if(block) return _match(tokens); // loop until we find something or nothing else return false; // return after just one attempted match } private static boolean _matchImmediate(List<String> tokens) { if(tokens != null) { for(int i = 0; i <= tokens.size(); i++) { if (i == tokens.size()) { // matches all tokens return true; } else if(!id.hasNext() || !id.next().matches(tokens.get(i))) { return false; // doesn't match, or end of file } } return false; // we have some serious problems if this ever gets called } else { return true; // empty list always matches } } Basically wondering how I would work in an efficient string search (Boyer-Moore or similar). My Scanner id is scanning a java.util.String, figured buffering it to memory would reduce I/O since the search here is being performed thousands of times on a relatively small file. The performance increase compared to scanning a BufferedReader(FileReader(File)) was probably less than 1%, the process still looks to be taking a LONG time. I've also traced execution and the slowness of my overall conversion process is definitely between the first and last like of the lookup method. In fact, so much so that I ran a shortcut process to count the number of occurrences of various identifiers in the .csv-style files (I use 2 lookup methods, this is just one of them) and the process completed indexing approx 4 different identifiers for 50,000 records in less than a minute. Compared to 12 hours, that's instant. Some notes (updated): I don't necessarily need the pattern-matching behaviour, I only get the first field of a line of text so I need to match line breaks or use Scanner.nextLine(). All ID numbers I need start at position 0 of a line and run through til the first block of whitespace, after which is the name of the corresponding object. I would ideally want to return a String, not an int locating the line number or start position of the result, but if it's faster then it will still work just fine. If an int is being returned, however, then I would now have to seek to that line again just to get the ID; storing the ID of every line that is searched sounds like a way around that. Anything to help me out, even if it saves 1ms per search, will help, so all input is appreciated. Thankyou! Usage scenario 1: I have a list of objects in file A, who in the old-style system have an id number which is not in file A. It is, however, POSSIBLY in another csv-style file (file B) or possibly still in a .txt report (file C) which each also contain a bunch of other information which is not useful here, and so file B needs to be searched through for the object's full name (1 token since it would reside within the second column of any given line), and then the first column should be the ID number. If that doesn't work, we then have to split the search token by whitespace into separate tokens before doing a search of file C for those tokens as well. Generalised code: String field; for (/* each record in file A */) { /* construct the rest of this object from file A info */ // now to find the ID, if we can List<String> objectName = new ArrayList<String>(1); objectName.add(Pattern.quote(thisObject.fullName)); field = lookup(objectSearchToken, objectName); // search file B if(field == null) // not found in file B { lookupReset(false); // initialise scanner to check file C objectName.clear(); // not using the full name String[] tokens = thisObject.fullName.split(id.delimiter().pattern()); for(String s : tokens) objectName.add(Pattern.quote(s)); field = lookup(objectSearchToken, objectName); // search file C lookupReset(true); // back to file B } else { /* found it, file B specific processing here */ } if(field != null) // found it in B or C thisObject.ID = field; } The objectName tokens are all uppercase words with possible hyphens or apostrophes in them, separated by spaces. Much like a person's name. As per a comment, I will pre-compile the regex for my objectSearchToken, which is just [\r\n]+. What's ending up happening in file C is, every single line is being checked, even the 95% of lines which don't contain an ID number and object name at the start. Would it be quicker to use ^[\r\n]+.*(objectname) instead of two separate regexes? It may reduce the number of _match executions. The more general case of that would be, concatenate all tokensBefore with all tokensAfter, and put a .* in the middle. It would need to be matching backwards through the file though, otherwise it would match the correct line but with a huge .* block in the middle with lots of lines. The above situation could be resolved if I could get java.util.Scanner to return the token previous to the current one after a call to findWithinHorizon. I have another usage scenario. Will put it up asap.

  • SQL Server insert with XML parameter - empty string not converting to null for numeric

    - by Mayo
    I have a stored procedure that takes an XML parameter and inserts the "Entity" nodes as records into a table. This works fine unless one of the numeric fields has a value of empty string in the XML. Then it throws an "error converting data type nvarchar to numeric" error. Is there a way for me to tell SQL to convert empty string to null for those numeric fields in the code below? -- @importData XML <- stored procedure param DECLARE @l_index INT EXECUTE sp_xml_preparedocument @l_index OUTPUT, @importData INSERT INTO dbo.myTable ( [field1] ,[field2] ,[field3] ) SELECT [field1] ,[field2] ,[field3] FROM OPENXML(@l_index, 'Entities/Entity', 1) WITH ( field1 int 'field1' ,field2 varchar(40) 'field2' ,field3 decimal(15, 2) 'field3' ) EXECUTE sp_xml_removedocument @l_index EDIT: And if it helps, sample XML. Error is thrown unless I comment out field3 in the code above or provide a value in field3 below. <?xml version="1.0" encoding="utf-16"?> <Entities> <Entity> <field1>2435</field1> <field2>843257-3242</field2> <field3 /> </Entity> </Entities>

  • Detect click on URL in RichEdit

    - by Tofig Hasanov
    I am trying to update RichEdit so that it detects URL and enables clicking on it to open in the browser. Detecting URL is easy, I just use the following code from http://www.scalabium.com/faq/dct0146.htm mask := SendMessage(MNote.Handle, EM_GETEVENTMASK, 0, 0); SendMessage(MNote.Handle, EM_SETEVENTMASK, 0, mask or ENM_LINK); SendMessage(MNote.Handle, EM_AUTOURLDETECT, Integer(True), 0); but the second part doesn't work for me. They give the following code to capture EN_LINK message and processing it: type TForm1 = class(TForm) protected procedure WndProc(var Message: TMessage); override; end; ... procedure TForm1.WndProc(var Message: TMessage); var p: TENLink; strURL: string; begin if (Message.Msg = WM_NOTIFY) then begin if (PNMHDR(Message.LParam).code = EN_LINK) then begin p := TENLink(Pointer(TWMNotify(Message).NMHdr)^); if (p.msg = WM_LBUTTONDOWN) then begin SendMessage(RichEdit1.Handle, EM_EXSETSEL, 0, LongInt(@(p.chrg))); strURL := RichEdit1.SelText; ShellExecute(Handle, 'open', PChar(strURL), 0, 0, SW_SHOWNORMAL); end end end; inherited; end; When I run the program, URL is detected, but clicking on it doesn't do anything. Using debug I found out that Message.Msg = WM_NOTIFY is not true when I click on URL. I then tried to override TRichEdit's WndProc, but result is the same. Any suggestions?

  • Improve speed of own debug visualizer for Delphi 2010

    - by netcodecz
    I wrote Delphi debug visualizer for TDataSet to display values of current row, source + screenshot: http://delphi.netcode.cz/text/tdataset-debug-visualizer.aspx . Working good, but very slow. I did some optimalization (how to get fieldnames) but still for only 20 fields takes 10 seconds to show - very bad. Main problem seems to be slow IOTAThread90.Evaluate used by main code shown below, this procedure cost most of time, line with ** about 80% time. FExpression is name of TDataset in code. procedure TDataSetViewerFrame.mFillData; var iCount: Integer; I: Integer; // sw: TStopwatch; s: string; begin // sw := TStopwatch.StartNew; iCount := StrToIntDef(Evaluate(FExpression+'.Fields.Count'), 0); for I := 0 to iCount - 1 do begin s:= s + Format('%s.Fields[%d].FieldName+'',''+', [FExpression, I]); // FFields.Add(Evaluate(Format('%s.Fields[%d].FieldName', [FExpression, I]))); FValues.Add(Evaluate(Format('%s.Fields[%d].Value', [FExpression, I]))); //** end; if s<> '' then Delete(s, length(s)-4, 5); s := Evaluate(s); s:= Copy(s, 2, Length(s) -2); FFields.CommaText := s; { sw.Stop; s := sw.Elapsed; Application.MessageBox(Pchar(s), '');} end; Now I have no idea how to improve performance.

  • Joining on a common table, how do you get a FULL OUTER JOIN to expand on another table?

    - by stimpy77
    I've scoured StackOverflow and Google for an answer to this problem. I'm trying to create a Microsot SQL Server 2008 view. Not a stored procedure. Not a function. Just a query (i.e. a view). I have three tables. The first table defines a common key, let's say "CompanyID". The other two tables have a sometimes-common field, let's say "EmployeeName". I want a single table result that, when my WHERE clause says "WHERE CompanyID = 12" looks like this: CompanyID | TableA | TableB 12 | John Doe | John Doe 12 | Betty Sue | NULL 12 | NULL | Billy Bob I've tried a FULL OUTER JOIN that looks like this: SELECT Company.CompanyID, TableA.EmployeeName, TableB.EmployeeName FROM Company FULL OUTER JOIN TableA ON Company.CompanyID = TableA.CompanyID FULL OUTER JOIN TableB ON Company.CompanyID = TableB.CompanyID AND (TableA.EmployeeName IS NULL OR TableB.EmployeeName IS NULL OR TableB.EmployeeName = TableA.EmployeeName) I'm only getting the NULL from one matched table, I'm not getting the expansion for the other table. In the above sample, I'm basically only getting the first and third rows and not the second. Can someone help me create this query and show me how this is done correctly? BTW I already have a stored procedure that looks very clean and populates an in-memory table, but that isn't what I want. Thanks.

  • SQL Full-Text Indexing Issue

    - by Phil
    UPDATE: I have figured out a way using a form of dynamic sql to fix this problem, thanks anyway for any help. Hi, there is something that I need to accomplish with the use of Full-Text Indexing. This is it: The fact of the matter is when I run a query (with a stored procedure) that looks like (with a parameter (@name) that was obviously defined above (not shown here), this parameter is sent to the stored procedure by an asp.net page, from user input): SELECT Name FROMdbo.UsersTable WHERE FREETEXT(Name, @name) Well, the fact of the matter is that a query like this will return values if, say the parameter @name's value is Joe, and say, there are 10 records of names with Joe in them, but if @name's value is just Jo, then it returns nothing, and this is the problem. Say that there are other records in this table that have Jo in them, like for example, Jole, or John. So the real question is, how do I get it to return values that are not full words, or phrases, but just from part of the word/phrase (like I said above)? Like FREETEXT(Name, @name*), which is not allowed to be used as a query, but, you get the idea. Is there a way to accomplish this? I'm sure there must be, I need to figure this out. Thanks for any help.

  • Sharepoint: Integrity of lookup fields after a list import

    - by driAn
    Hi there I got a question about the behavior of lookup fields when importing data. I wonder how the lookup fields behave when the list they point to is being replaced/imported. To explain the issue, I will provide a quick example below: As example, assume we have these two sharepoint lists: Product Types ------------- + Type Name + Code Nr + etc Products -------- + Product Name + Product Type (Lookup field to list "Product Types") + etc In my scenario, the Products List contains production data on the production Sharepoint platform. It is filled with data by the business users. However the Product Types list contains rather static data and is maintained by the developer. Now after a development cycle, the developer wants to deploy his new webparts and his new data (product types list). The developer performs the following procedure: On the dev machine: Export "product type" list using stsadm On the production machine: Delete all items in the "product type" list On the production machine: Import the "product type" list using stsadm This means we basically replace the "product type" list on the production server while keeping the "product" list as it is. Now the question: Is this safe? Will the lookup references break under certain circumstances? Any downside of this import/export procedure? What happens if someone accesses a "product" during the import? Will the (now invalid) reference clear its own content (become a null value). What happens if the schema of the "product type" list changes (new column)? Will this cause any troubles? Thanks for all feedback and suggestions!

  • Generating the SQL query plan takes 5 minutes, the query itself runs in milliseconds. What's up?

    - by TheImirOfGroofunkistan
    I have a fairly complex (or ugly depending on how you look at it) stored procedure running on SQL Server 2008. It bases a lot of the logic on a view that has a pk table and a fk table. The fk table is left joined to the pk table slightly more than 30 times (the fk table has a poor design - it uses name value pairs that I need to flatten out. Unfortunately, it's 3rd party and I cannot change it). Anyway, it had been running fine for weeks until I periodically noticed a run that would take 3-5 minutes. It turns out that this is the time it takes to generate the query plan. Once the query plan exists and is cached, the stored procedure itself runs very efficiently. Things run smoothly until there is a reason to regenerate and cache the query plan again. Has anyone seen this? Why does it take so long to generate the plan? Are there ways to make it come up with a plan faster?

  • ASP Classic, SQL 2008, XML Output, and DSN vs DSN-Less Produces Chinese Letters

    - by RoLYroLLs
    I've been having a problem for the past month and can't seem to figure out what is wrong. Here's the setup and a little background. Background: I have a web-host who was running my website on Windows Server 2003 and SQL Server 2000. One of my webpages returned a result set from a stored procedure from the SQL server as xml. Below is the code: Stored Procedure: select top 10 1 as tag , null as parent , column1 as [item!1!column1!element] , column2 as [item!1!column2!element] from table1 for XML EXPLICIT ASP Page: index.asp Call OpenConn Set cmd = Server.CreateObject("ADODB.Command") With cmd .ActiveConnection = dbc .CommandText = "name of proc" .CommandType = adCmdStoredProc .Parameters.Append .CreateParameter("@RetVal", adInteger, adParamReturnValue, 4) .Parameters.Append .CreateParameter("@Level", adInteger, adParamInput, 4, Level) End With Set rsItems = Server.CreateObject("ADODB.Recordset") With rsItems .CursorLocation = adUseClient .CursorType = adOpenStatic .LockType = adLockBatchOptimistic Set .Source = cmd .Open Set .ActiveConnection = Nothing End With If NOT rsItems.BOF AND NOT rsItems.EOF Then OutputXMLQueryResults rsItems,"items" End If Set rsItems = Nothing Set cmd = Nothing Call CloseConn Sub OpenConn() strConn = "Provider=SQLOLEDB;Data Source=[hidden];User Id=[hidden];Password=[hidden];Initial Catalog=[hidden];" Set dbc = Server.CreateObject("ADODB.Connection") dbc.open strConn End Sub Sub CloseConn() If IsObject(dbc) Then If dbc.State = adStateOpen Then dbc.Close End If Set dbc = Nothing End If End Sub Sub OutputXMLQueryResults(RS,RootElementName) Response.Clear Response.ContentType = "text/xml" Response.Codepage = 65001 Response.Charset = "utf-8" Response.Write "" Response.Write "" While Not RS.EOF Response.Write RS(0).Value RS.MoveNext WEnd Response.Write "" Response.End End Sub Present: All was working great, until my host upgraded to Windows Server 2008 and SQL Server 2008. All of the sudden I was getting results like this: From Browser: From View Source: However, I found that if I use a DSN connection strConn = "DSN=[my DSN Name];User Id=[hidden];Password=[hidden];Initial Catalog=[hidden];" it works perfectly fine! My current host is not going to support DSN any longer, but that's out of scope for this issue. Someone told me to use an ADO.Stream object instead of a Recordset object, but I'm unsure how to implement that. Question: Has anyone run into this and found a way to fix it? What about that ADO.Stream object, can someone help me with a sample that would fit my code?

EDIT: I'm asking this, because when I do the same, onExecute I access AContext.Data , and sometimes (when in same time is connecting many clients) AContext.Data is empty, access violation appears.

  • Bubble sort algorithm implementations (Haskell vs. C)

    - by kingping
    Hello. I have written 2 implementation of bubble sort algorithm in C and Haskell. Haskell implementation: module Main where main = do contents <- readFile "./data" print "Data loaded. Sorting.." let newcontents = bubblesort contents writeFile "./data_new_ghc" newcontents print "Sorting done" bubblesort list = sort list [] False rev = reverse -- separated. To see rev2 = reverse -- who calls the routine sort (x1:x2:xs) acc _ | x1 > x2 = sort (x1:xs) (x2:acc) True sort (x1:xs) acc flag = sort xs (x1:acc) flag sort [] acc True = sort (rev acc) [] False sort _ acc _ = rev2 acc I've compared these two implementations having run both on file with size of 20 KiB. C implementation took about a second, Haskell — about 1 min 10 sec. I have also profiled the Haskell application: Compile for profiling: C:\Temp ghc -prof -auto-all -O --make Main Profile: C:\Temp Main.exe +RTS -p and got these results. This is a pseudocode of the algorithm: procedure bubbleSort( A : list of sortable items ) defined as: do swapped := false for each i in 0 to length(A) - 2 inclusive do: if A[i] > A[i+1] then swap( A[i], A[i+1] ) swapped := true end if end for while swapped end procedure I wonder if it's possible to make Haskell implementation work faster without changing the algorithm (there's are actually a few tricks to make it work faster, but neither implementations have these optimizations)

    Hi! Im using NSXMLParser to dissect a xml package, I'm receiving &apos inside the package text. I have the following defined for the xmlParser: [xmlParser setShouldResolveExternalEntities: YES]; The following method is never called - (void)parser:(NSXMLParser *)parser foundExternalEntityDeclarationWithName:(NSString *)entityName publicID:(NSString *)publicID systemID:(NSString *)systemID The text in the field before the &apos is not considered by the parser. Im searching how to solve this, any idea???

  • RadAjaxManager problem when showing/hiding control on page loading

    - by Lukasz Lysik
    I have the webform with dropdown list, label and textbox. Like below: <asp:DropDownList ID="ddlTest" runat="server" AutoPostBack="true"> </asp:DropDownList> <asp:Label ID="lblTest" runat="server" Text="Some text"> </asp:Label> <asp:TextBox ID="edtTest" runat="server"> </asp:TextBox> I want to show/hide label and text box depending on the value selected on dropdown list. So I've added RadAjaxManader: <rad:RadAjaxManager ID="RadAjaxManager1" runat="server"> <AjaxSettings> <rad:AjaxSetting AjaxControlID="ddlTest"> <UpdatedControls> <rad:AjaxUpdatedControl ControlID="lblTest" /> <rad:AjaxUpdatedControl ControlID="edtTest" /> </UpdatedControls> </rad:AjaxSetting> </AjaxSettings> </rad:RadAjaxManager> and procedure "SetupVisibility" which takes value from the dropdown list, does some walidations and desides whether to show or hide the label and the text box. When I use the procedure like this: Protected Sub ddlTest_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlTest.SelectedIndexChanged SetupVisibility() End Sub it works good, but now I want to call SetupVisibility when the page is loaded: Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init SetupVisibility() End Sub The problem occurs in such a scenario: SetupVisibility() hides textbox and label while page is loaded. I change value on ddlTest dropdown list. SetupVisibility() wants to show textbox and label, but then I get the error: Microsoft JScript - runtime error: Cannot update control with ID: ctl00_CPH1_lblTest. The control does not exist. Where is the problem?

  • MS Access Interop - How to set print filename?

    - by Ryan
    Hi all, I'm using Delphi 2009 and the MS Access Interop COM API. I'm trying to figure out two things, but one is more important than the other right now. I need to know how to set the file name when sending the print job to the spooler. Right now it's defaulting to the Access DB's name, which can be something different than the file's name. I need to just ensure that when this is printed it enters the print spool using the same filename as the actual file itself - not the DB's name. My printer spool is actually a virtual print driver that converts documents to an image. That's my main issue. The second issue is how to specify which printer to use. This is less important at the moment because I'm just using the default printer for now. It would be nice if I could specify the printer to use, though. Does anyone know either of these two issues? Thank you in advance. I'll go ahead and paste my code: unit Converter.Handlers.Office.Access; interface uses sysutils, variants, Converter.Printer, Office_TLB, Access_TLB, UDC_TLB; procedure ToTiff(p_Printer: PrinterDriver; p_InputFile, p_OutputFile: String); implementation procedure ToTiff(p_Printer: PrinterDriver; p_InputFile, p_OutputFile: String); var AccessApp : AccessApplication; begin AccessApp := CoAccessApplication.Create; AccessApp.Visible := False; try AccessApp.OpenCurrentDatabase(p_InputFile, True, ''); AccessApp.RunCommand(acCmdQuickPrint); AccessApp.CloseCurrentDatabase; finally AccessApp.Quit(acQuitSaveNone); end; end; end.

  • How to print the address an ada access variable points to?

    - by georg
    I want to print the address of an access variable (pointer) for debugging purposes. type Node is private; type Node_Ptr is access Node; procedure foo(n: in out Node_Ptr) is package Address_Node is new System.Address_To_Access_Conversions(Node); use Address_Node; begin Put_Line("node at address " & System.Address_Image(To_Address(n))); end foo; Address_Image returns the string representation of an address. System.Address_To_Access_Conversions is a generic package to convert between addresses and access types (see ARM 13.7.2), defined as follows: generic type Object(<>) is limited private; package System.Address_To_Access_Conversions is -- [...] type Object_Pointer is access all Object; -- [...] function To_Address(Value : Object_Pointer) return Address; -- [...] end System.Address_To_Access_Conversions; gnat gives me the following errors for procedure foo defined above: expected type "System.Address_To_Access_Conversions.Object_Pointer" from instance at line... found type "Node_Ptr" defined at ... Object_Pointer ist definied as access all Object. From my understanding the type Object is Node, therefore Object_Ptr is access all Node. What is gnat complaining about? I guess my understanding of Ada generics is flawed and I am not using System.Address_To_Access_Conversions correctly. EDIT: I compiled my code with "gnatmake -gnatG" to see the generic instantiation: package address_node is subtype btree__clear__address_node__object__2 is btree__node; type btree__clear__address_node__object_pointer__2 is access all btree__clear__address_node__object__2; function to_address (value : btree__clear__address_node__object_pointer__2) return system__address; end address_node; btree__node is the mangled name of the type Node as defined above, so I really think the parameter type for to_address() is correct, yet gnat is complaining (see above).

  • Problem with ASP.NET Authentication

    - by Niels Bosma
    I'm having problem with our login procedure. Some customers complain that they can't login. I can see in our logs that their login is successful and that they are redirected from the login page to the member area. But there somehow the login isn't detected and they are bounced back to the login page. I've asked customers to check if cookies are supported (http://www.html-kit.com/tools/cookietester/) but problem remains even if this test returns true. This is how I've implemented the login procedure (simplyfied): protected void Login(string email, string password) { FormsAuthentication.SignOut(); Guid clientId = /* Validate login by checking email and password, if fails display error otherwise get client id */ FormsAuthentication.SetAuthCookie(clientId.ToString(), true); HttpContext.Current.Response.Redirect("~/Members.aspx"); } On the member page I check for authentication by in Page_Load function: public static void IsAuthenticated() { if (!HttpContext.Current.User.Identity.IsAuthenticated) { HttpContext.Current.Response.Redirect("~/Login.aspx", true); } } Maybe I'm using FormsAuthentication completely wrong? I've asked this before but still haven't been able to figure this out, I'd appreciate any help.

  • Delphi Application using COMMIT and ROLLBACK for Multiple SQL Updates

    - by Matt
    Is it possible to use the SQL BEGIN TRANSACTION, COMMIT TRANSACTION, ROLLBACK TRANSACTION when embedding SQL Queries into an application with mutiple calls to the SQL for Table Updates. For example I have the following code: Q.SQL.ADD(<UPDATE A RECORD>); Q.ExecSQL; Q.Close; Q.SQL.Clear; Q.SQL.ADD(<Select Some Data>); Q.Open; Set Some Variables Q.Close; Q.SQL.Clear; Q.SQL.ADD(<UPDATE A RECORD>); Q.ExecSQL; What I would like to do is if the second update fails I want to roll back the first transaction. If I set a unique notation for the BEGIN, COMMIT, ROLLBACK so as to specify what is being committed or rolled back, is it feasible. i.e. before the first Update specify BEGIN TRANSACTION_A then after the last update specify COMMIT TRANSACTION_A I hope that makes sense. If I was doing this in a SQL Stored Procedure then I would be able to specify this at the start and end of the procedure, but I have had to break the code down into manageable chunks due to process blocks and deadlocks on a heavy loaded SQL Server.
