  • Check if files in a directory are still being written in Windows Batch File

    - by FMFF
    Hello. Here's my batch file to parse a directory, and zip files of certain type REM Begin ------------------------ tasklist /FI "IMAGENAME eq 7za.exe" /FO CSV > search.log FOR /F %%A IN (search.log) DO IF %%~zA EQU 0 GOTO end for /f "delims=" %%A in ('dir C:\Temp\*.ps /b') do ( "C:\Program Files\7-Zip\cmdline\7za.exe" a -tzip -mx9 "C:\temp\Zip\%%A.zip" "C:\temp\%%A" Move "C:\temp\%%A" "C:\Temp\Archive" ) :end del search.log REM pause exit REM End --------------------------- This code works just fine for 90% of my needs. It will be deployed as a scheduled task. However, the *.ps files are rather large (minimum of 1GB) in real time cases. So the code is supposed to check if the incoming file is completely written and is not locked by the application that is writing it. I saw another example elsewhere, that suggested the following approach :TestFile ren c:\file.txt c:\file.txt if errorlevel 0 goto docopy sleep 5 goto TestFile :docopy However this example is good for a fixed file. How can I use that many labels and GoTo's inside a for loop without causing an infinite loop? Or is this code safe to be used in the For Loop? Thank you for any help.

  • Insert video clip in a lyx presentation and play it in GNU/Linux.

    - by Orjanp
    How can I insert a video clip into a presentation created in Lyx? Have seen http://www.latex-community.org/forum/viewtopic.php?f=19&t=48. It works, but there the video starts in the background in an external player. I would prefer it to be played in the presentation itself. If an external player is used it it should at least start in the foreground. But the presentation takes the foreground. Using evince in GNU/linux as pdf viewer. Beamer is used as a presentation template. Is it possible to play a video file in an embedded player in the presentation itself? Created an example presentation. The code is found below. \documentclass[english]{beamer} \usepackage{mathptmx} \usepackage[T1]{fontenc} \usepackage[latin9]{inputenc} \usepackage{amsmath} \usepackage{amssymb} \makeatletter %%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Textclass specific LaTeX commands. % this default might be overridden by plain title style \newcommand\makebeamertitle{\frame{\maketitle}}% \AtBeginDocument{ \let\origtableofcontents=\tableofcontents \def\tableofcontents{\@ifnextchar[{\origtableofcontents}{\gobbletableofcontents}} \def\gobbletableofcontents#1{\origtableofcontents} } \makeatletter \long\def\lyxframe#1{\@lyxframe#1\@lyxframestop}% \def\@lyxframe{\@ifnextchar<{\@@lyxframe}{\@@lyxframe<*>}}% \def\@@lyxframe<#1>{\@ifnextchar[{\@@@lyxframe<#1>}{\@@@lyxframe<#1>[]}} \def\@@@lyxframe<#1>[{\@ifnextchar<{\@@@@@lyxframe<#1>[}{\@@@@lyxframe<#1>[<*>][}} \def\@@@@@lyxframe<#1>[#2]{\@ifnextchar[{\@@@@lyxframe<#1>[#2]}{\@@@@lyxframe<#1>[#2][]}} \long\def\@@@@lyxframe<#1>[#2][#3]#4\@lyxframestop#5\lyxframeend{% \frame<#1>[#2][#3]{\frametitle{#4}#5}} \makeatother \def\lyxframeend{} % In case there is a superfluous frame end %%%%%%%%%%%%%%%%%%%%%%%%%%%%%% User specified LaTeX commands. \usetheme{Warsaw} \usepackage{hyperref} \makeatother \usepackage{babel} \begin{document} \title{Testing video} \makebeamertitle \lyxframeend{}\section{Testing video} \lyxframeend{}\subsection{Testing video} \lyxframeend{}\lyxframe{Testing video} \href{run:video.wmv}{Movie} \appendix \lyxframeend{} \end{document}

  • Performance problem with System.Net.Mail

    - by Saif Khan
    I have this unusual problem with mailing from my app. At first it wasn't working (getting unable to relay error crap) anyways I added the proper authentication and it works. My problem now is, if I try to send around 300 emails (each with a 500k attachment) the app starts hanging around 95% thru the process. Here is some of my code which is called for each mail to be sent Using mail As New MailMessage() With mail .From = New MailAddress(My.Resources.EmailFrom) For Each contact As Contact In Contacts .To.Add(contact.Email) Next .Subject = "Accounting" .Body = My.Resources.EmailBody 'Back the stream up to the beginning orelse the attachment 'will be sent as a zero (0) byte file. attachment.Seek(0, SeekOrigin.Begin) .Attachments.Add(New Attachment(attachment, String.Concat(Item.Year, Item.AttachmentType.Extension))) End With Dim smtp As New SmtpClient("192.168.1.2") With smtp .DeliveryMethod = SmtpDeliveryMethod.Network .UseDefaultCredentials = False .Credentials = New NetworkCredential("username", "password") .Send(mail) End With End Using With item .SentStatus = True .DateSent = DateTime.Now.Date .Save() End With Return I was thinking, can I just prepare all the mails and add them to a collection then open one SMTP conenction and just iterate the collection, calling the send like this Using mail As New MailMessage() ... MailCollection.Add(mail) End Using ... Dim smtp As New SmtpClient("192.168.1.2") With smtp .DeliveryMethod = SmtpDeliveryMethod.Network .UseDefaultCredentials = False .Credentials = New NetworkCredential("username", "password") For Each mail in MainCollection .Send(mail) Next End With

  • Problems with Runt overlap? but *only* within Rails

    - by trisignia
    Martin Fowler's Runt library is really handy for date/time comparisons, and this code works great in an irb console: require 'runt' include Runt r_start = PDate.month(2010,12) r_end = PDate.month(2011,12) range = DateRange.new(r_start,r_end) o_start = PDate.month(2010,11) o_end = PDate.month(2012,2) o_range = DateRange.new(o_start,o_end) range.overlap?(o_range) but if I add the Runt gem to my Rails 2.3.5 app and try to run the same commands in script/console, I get this error: NoMethodError: undefined method `to_datetime' for Mon, 01 Nov 2010 00:00:00 +0000..Wed, 01 Feb 2012 00:00:00 +0000:Runt::DateRange from /Users/jacob/work/matchbook/vendor/gems/runt-0.7.6/lib/runt/sugar.rb:130:in method_missing' from /Users/jacob/work/matchbook/vendor/rails/activesupport/lib/active_support/core_ext/date_time/calculations.rb:120:in <=' from /Users/jacob/work/matchbook/vendor/gems/runt-0.7.6/lib/runt/pdate.rb:91:in <=>' from /Users/jacob/work/matchbook/vendor/gems/runt-0.7.6/lib/runt/daterange.rb:34:in member?' from /Users/jacob/work/matchbook/vendor/gems/runt-0.7.6/lib/runt/daterange.rb:34:in `overlap?' from (irb):10 Has anyone encountered this error before, or does anyone know how to begin debugging this? I've tried looking at the spaceship operator in the ActiveSupport calculations module, but I can't figure out how to pick apart the problem. Thanks very much for your help, Jacob

  • The woes of (sometimes) storing "date only" in datetimes

    - by Heinzi
    We have two fields from and to (of type datetime), where the user can store the begin time and the end time of a business trip, e.g.: From: 2010-04-14 09:00 To: 2010-04-16 16:30 So, the duration of the trip is 2 days and 7.5 hours. Often, the exact times are not known in advance, so the user enters the dates without a time: From: 2010-04-14 To: 2010-04-16 Internally, this is stored as 2010-04-14 00:00 and 2010-04-16 00:00, since that's what most modern class libraries (e.g. .net) and databases (e.g. SQL Server) do when you store a "date only" in a datetime structure. Usually, this makes perfect sense. However, when entering 2010-04-16 as the to date, the user clearly did not mean 2010-04-16 00:00. Instead, the user meant 2010-04-16 24:00, i.e., calculating the duration of the trip should output 3 days, not 2 days. I can think of a few (more or less ugly) workarounds for this problem (add "23:59" in the UI layer of the to field if the user did not enter a time component; add a special "dates are full days" Boolean field; store "2010-04-17 00:00" in the DB but display "2010-04-16 24:00" to the user if the time component is "00:00"; ...), all having advantages and disadvantages. Since I assume that this is a fairly common problem, I was wondering: Is there a "standard" best-practice way of solving it? If there isn't, have you experienced a similar requirement, how did you solve it and what were the pros/cons of that solution?

  • Improving Performance of Crystal Reports using Stored Procedures

    - by mjh41
    Recently I updated a Crystal Report that was doing all of its work on the client-side (Selects, formulas, etc) and changed all of the logic to be done on the server-side through Stored Procedures using an Oracle 11g database. Now the report is only being used to display the output of the stored procedures and nothing else. Everything I have read on this subject says that utilizing stored procedures should greatly reduce the running time of the report, but it still takes roughly the same amount of time to retrieve the data from the server. Is there something wrong with the stored procedure I have written, or is the issue in the Crystal Report itself? Here is the stored procedure code along with the package that defines the necessary REF CURSOR. CREATE OR REPLACE PROCEDURE SP90_INVENTORYDATA_ALL ( invdata_cur IN OUT sftnecm.inv_data_all_pkg.inv_data_all_type, dCurrentEndDate IN vw_METADATA.CASEENTRCVDDATE%type, dCurrentStartDate IN vw_METADATA.CASEENTRCVDDATE%type ) AS BEGIN OPEN invdata_cur FOR SELECT vw_METADATA.CREATIONTIME, vw_METADATA.RESRESOLUTIONDATE, vw_METADATA.CASEENTRCVDDATE, vw_METADATA.CASESTATUS, vw_METADATA.CASENUMBER, (CASE WHEN vw_METADATA.CASEENTRCVDDATE < dCurrentStartDate AND ( (vw_METADATA.CASESTATUS is null OR vw_METADATA.CASESTATUS != 'Closed') OR TO_DATE(vw_METADATA.RESRESOLUTIONDATE, 'MM/DD/YYYY') >= dCurrentStartDate) then 1 else 0 end) InventoryBegin, (CASE WHEN (to_date(vw_METADATA.RESRESOLUTIONDATE, 'MM/DD/YYYY') BETWEEN dCurrentStartDate AND dCurrentEndDate) AND vw_METADATA.RESRESOLUTIONDATE is not null AND vw_METADATA.CASESTATUS is not null then 1 else 0 end) CaseClosed, (CASE WHEN vw_METADATA.CASEENTRCVDDATE BETWEEN dCurrentStartDate AND dCurrentEndDate then 1 else 0 end) CaseCreated FROM vw_METADATA WHERE vw_METADATA.CASEENTRCVDDATE <= dCurrentEndDate ORDER BY vw_METADATA.CREATIONTIME, vw_METADATA.CASESTATUS; END SP90_INVENTORYDATA_ALL; And the package: CREATE OR REPLACE PACKAGE inv_data_all_pkg AS TYPE inv_data_all_type IS REF CURSOR RETURN inv_data_all_temp%ROWTYPE; END inv_data_all_pkg;

  • Javascript Detect Control Key Held on Mouseup

    - by Michael Mikowski
    I've searched a good deal, and can't seem to find a satisfactory solution. I hope someone can help. While I am using jQuery, I am also writing many thousands of lines of Javascript. So a "pure" javascript solution is just fine. I'm trying to determine if the control key is physically held down on a mouseup event. That's it; there are no other preconditions. Does anyone know how to do this reliably, cross-browser? I've tried storing this in a state variable by noting when the key is pressed and released: // BEGIN store control key status in hash_state $().bind('keydown','ctrl',function( arg_obj_e ){ hash_state.sw_ctrldn = true; console.debug( hash_state.sw_ctrldn ); }); $().bind('keyup','ctrl',function( arg_obj_e ){ hash_state.sw_ctrldn = false; console.debug( hash_state.sw_ctrldn ); }); // END store control key status in hash_state However, this really doesn't work. If you test this using firebug and watch the console, you will see that auto-repeat seems to happen, and the value toggles. I inspected the mouseup event to see if there is anything useful there, but to no avail: var debugEvent = function( arg_obj_e ){ var str = ''; for ( var attr in arg_obj_e ){ str += attr + ': ' + arg_obj_e[attr] + '\n'; } console.debug(str); } Any help would be appreciated.

  • Proxy is created, and interceptor is in the __interceptors array, but the interceptor is never calle

  • Problem with oracle stored procedure - parameters

    - by Nicole
    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 I tried with the datetime and was not the problem, I eve tried with no input parameters and just the output and still got the same error. Aparently the problem is with the output parameter. I already tried putting p_Detalle OUT VARCHAR2 instead of p_Detalle OUT LIQUIDACION.FILADETALLE%TYPE but it didn't work either I hope my post is understandable.. thanks!!!!!!!!!!

  • C# using consts in static classes

    - by NickLarsen
    I was plugging away on an open source project this past weekend when I ran into a bit of code that confused me to look up the usage in the C# specification. The code in questions is as follows: internal static class SomeStaticClass { private const int CommonlyUsedValue = 42; internal static string UseCommonlyUsedValue(...) { // some code value = CommonlyUsedValue + ...; return value.ToString(); } } I was caught off guard because this appears to be a non static field being used by a static function which some how compiled just fine in a static class! The specification states (§10.4): A constant-declaration may include a set of attributes (§17), a new modifier (§10.3.4), and a valid combination of the four access modifiers (§10.3.5). The attributes and modifiers apply to all of the members declared by the constant-declaration. Even though constants are considered static members, a constant-declaration neither requires nor allows a static modifier. It is an error for the same modifier to appear multiple times in a constant declaration. So now it makes a little more sense because constants are considered static members, but the rest of the sentence is a bit surprising to me. Why is it that a constant-declaration neither requires nor allows a static modifier? Admittedly I did not know the spec well enough for this to immediately make sense in the first place, but why was the decision made to not force constants to use the static modifier if they are considered constants? Looking at the last sentence in that paragraph, I cannot figure out if it is regarding the previous statement directly and there is some implicit static modifier on constants to begin with, or if it stands on its own as another rule for constants. Can anyone help me clear this up?

  • Multi-base conversion - using all combinations for URL shortener

    - by Guffa
    I am making an URL shortener, and I am struggling with the optimal way of encoding a number (id) into a character string. I am using the characters 0-9,A-Z,a-z so it will basically be a base-62 encoding. That is pretty basic, but it doesn't make use of all possible codes. The codes that it would produce would be: 0, 1, ... y, z, 10, 11, ... zy, zz, 100, 101, ... Notice that the codes 00 to 0z is not used, the same for 000 to 0zz, and so on. I would like to use all the codes, like this: 0, 1, ... y, z, 00, 01, ... zy, zz, 000, 001, ... It would be some combination of base-62 and base-63, with different bases depending on the position... Using base-62 is easy, for example: create procedure tiny_GetCode @UrlId int as set nocount on declare @Code varchar(10) set @Code = '' while (@UrlId > 0 or len(@Code) = 0) begin set @Code = substring('0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz', @UrlId % 62 + 1, 1) + @Code set @UrlId = @UrlId / 62 end select @Code But I haven't yet managed to make a multi-base conversion out of it, to make use of all the codes.

  • Classic ASP to WCF using the Service Moniker

    - by Jab
    I am trying to consume a WCF logging service from classic ASP without deploy a Com wrapper. I found a method of doing so here. Here is the vb script, simplified. Dim addr addr = "service:mexAddress=""net.pipe://localhost/Services/Logging/LoggingManager/Mex""," _ & "address=""net.pipe://localhost/Services/Logging/LoggingManager/classic/""," _ & "contract=""ILoggingManagerClassic"", contractNamespace=""http://Services.Logging.Classic/""," _ & "binding=""NetNamedPipeBinding_ILoggingManagerClassic"", bindingNamespace=""http://Services.Logging.Classic/""" set objErrorLogger = GetObject(addr) Dim strError : strError = objErrorLogger.LogError("blahblah") This works on Server 2008, but fails with this error on Server 2003. Failed to do mex retrieval:Metadata contains a reference that cannot be resolved: net.pipe://localhost/Services/Logging/LoggingManager/Mex.. Only when running through ASP does it fail, a sample VBS file on the same machine using the same code works fine. I think it may be permission related, but don't know where to begin. Anyone have any ideas? EDIT - let me clarify that the WCF host is a windows service running as NETWORK SERVICE. If this belongs on server fault, a moderator can move it. I have an account there as well.

  • Problem counting item frequency on T-SQL

    - by Raúl Roa
    I'm trying to count the frequency of numbers from 1 to 100 on different fields of a table. Let's say I have the table "Results" with the following data: LottoId Winner Second Third --------- --------- --------- --------- 1 1 2 3 2 1 2 3 I'd like to be able to get the frequency per numbers. For that I'm using the following code: --Creating numbers temp table CREATE TABLE #Numbers( Number int) --Inserting the numbers into the temp table declare @counter int set @counter = 0 while @counter < 100 begin set @counter = @counter + 1 INSERT INTO #Numbers(Number) VALUES(@counter) end -- SELECT #Numbers.Number, Count(Results.Winner) as Winner,Count(Results.Second) as Second, Count(Results.Third) as Third FROM #Numbers LEFT JOIN Results ON #Numbers.Number = Results.Winner OR #Numbers.Number = Results.Second OR #Numbers.Number = Results.Third GROUP BY #Numbers.Number The problem is that the counts are repeating the same values for each number. In this particular case I'm getting the following result: Number Winner Second Third --------- --------- --------- --------- 1 2 2 2 2 2 2 2 3 2 2 2 ... When I should get this: Number Winner Second Third --------- --------- --------- --------- 1 2 0 0 2 0 2 0 3 0 0 2 ... What am I missing?

  • Storing PLSQL stored-procedure values in Oracle memory caches for extended periods

    - by Ira Baxter
    I am collecting runtime profiling data from PLSQL stored procedures. The data is collected as certain stored procedures execute, but it needs to accumululate across multiple executions of those procedures. To minimize overhead, I'd like to store that profiling data in some PLSQL-accessable Oracle memory-resident storage somewhere for the duration of the data collection interval, and then dump out the accumulated values. The data collection interval might be seconds or hours; its ok not to store this data across system boots. Something like session state in web servers would do. What are my choices for storing such data? The only method I know about are contexts in dbms_sessions: procedure set_ctx (value in varchar8) as begin dbms_session.set_context ( 'Test_Ctx', 'AccumulatedValue', value, NULL, 'ProfilerSessionId' ); end set_ctx; This works, but takes some 50 milliseconds(!) per update to the accumulated value. What I'm hoping for is a way to access/store an array of values in some Oracle memory using vanilla PLSQL statements, with access times typical of array accesses made to package-local arrays.

    Hi, I have this task and i can't figure out how to do it. I need to find persons age in days, there are given birth and death dates, there's data file: 8 Albertas Einšteinas 1879 03 14 1955 04 18 Balys Sruoga 1896 02 02 1947 10 16 Antanas Vienuolis 1882 04 07 1957 08 17 Ernestas Rezerfordas 1871 08 30 1937 10 17 Nilsas Boras 1885 10 07 1962 11 18 Nežiniukas Pirmasis 8 05 24 8 05 25 Nežiniukas Antrasis 888 05 25 888 05 25 Nežiniukas Treciasis 1 01 01 125 01 01 and there's how result file should look like: 1879 3 14 1955 4 18 27775 1896 2 2 1947 10 16 18871 1882 4 7 1957 8 17 27507 1871 8 30 1937 10 17 24138 1885 10 7 1962 11 18 28147 8 5 24 8 5 25 1 888 5 25 888 5 25 0 1 1 1 125 1 1 45260 Few things to notice: all februarys have 28 days.

    Hi, I have a list<struct sockaddr_in> _peers I'd like to use for sendto() the list is filled this way struct hostent *hp; hp = gethostbyname(hostname); sockaddr_in sin; bzero(&sin, sizeof(sin)); sin.sin_family = AF_INET; sin.sin_port = htons(port); sin.sin_addr.s_addr = *(in_addr_t *)hp->h_addr; _peers.push_front(sin); and here's how I try to send: for (list<struct sockaddr_in>::iterator it = _peers.begin(); it != _peers.end(); ++it) { if (sendto(_s, "PING", 5, 0, (struct sockaddr *)&(*it), sizeof(struct sockaddr_in)) < 0) perror("sendto"); } outputs: sendto: Invalid argument If I create the struct sockaddr_in right before sendto(), everything works fine, so I guess I fail at using the list properly ... I also tested using &_peers.front() directly and still get the same error ... what am I doing wrong? Thanks in advance,

    I remember coming across an article on I think CodeProject quite some time ago regarding an antivirus or antimalware some guy was writing where he hooked into the Windows API to be able to catch whenever a new process was started and was prompting he user before allowing the process to start. I can no longer find the article, and would actually like to be able to implement something like this. Currently, we have a custom browser built on Gecko that we've integrated access restrictions to sites based on our internal employee security levels, etc. We prevent any other browser from running with a timer and a call to Process.GetProcessesByName() from a list of the browsers we don't allow. What we want to accomplish is, instead of just blocking these browsers, where there is a small delay between the other browser starting and it being killed by our service, we'd like to be able to display a dialog instead of the process launching at all, explaining that the program isn't in the allowed list. This way, we can generate a list of "allowed" processes and just block everything else (we haven't yet had a problem with outside apps being installed, but you can never be too careful). Unfortunately, we don't do much Windows API programming from C#, so I'm not sure where to begin looking for what calls we need to hook. Even just a starting point of what to read up on would be helpful.

  • Algorithm to match list of regular expressions

    - by DSII
    I have two algorithmic questions for a project I am working on. I have thought about these, and have some suspicions, but I would love to hear the community's input as well. Suppose I have a string, and a list of N regular expressions (actually they are wildcard patterns representing a subset of full regex functionality). I want to know whether the string matches at least one of the regular expressions in the list. Is there a data structure that can allow me to match the string against the list of regular expressions in sublinear (presumably logarithmic) time? This is an extension of the previous problem. Suppose I have the same situation: a string and a list of N regular expressions, only now each of the regular expressions is paired with an offset within the string at which the match must begin (or, if you prefer, each of the regular expressions must match a substring of the given string beginning at the given offset). To give an example, suppose I had the string: This is a test string and the regex patterns and offsets: (a) his.* at offset 0 (b) his.* at offset 1 The algorithm should return true. Although regex (a) does not match the string beginning at offset 0, regex (b) does match the substring beginning at offset 1 ("his is a test string"). Is there a data structure that can allow me to solve this problem in sublinear time? One possibly useful piece of information is that often, many of the offsets in the list of regular expressions are the same (i.e. often we are matching the substring at offset X many times). This may be useful to leverage the solution to problem #1 above. Thank you very much in advance for any suggestions you may have!

  • Make an ActiveX control work without a form?

    - by Earlz
    We are using Topaz Signature pads. They provide their APIs in the from of an ActiveX control which is to be put on a Winform control. Well, the way our project will work we do not want to have a form(at least not visible). We just want for the signature ActiveX control to get an image in the background. static AxSigPlus sig = new AxSIGPLUSLib.AxSigPlus(); public static void Begin() { ((System.ComponentModel.ISupportInitialize)(sig)).BeginInit(); sig.Name = "sig"; sig.Location = new System.Drawing.Point(0, 0); sig.Size = new System.Drawing.Size(0, 0); sig.Enabled = true; sig.TabletState = 1; //error here sig.SigCompressionMode = 0; } Ok so I get an error at the marked line. The exception is Exception of type 'System.Windows.Forms.AxHost+InvalidActiveXStateException' was thrown. What do I do to solve this problem? Would it just be easier to create a new hidden form and put the control on it so it's invisible?

  • SL 3 navigation not working!

    - by Silver Gun
    Hey Guys I converted all my existing Silverlight app UserControls to Pages so I could use the Navigation Framework. Anyway so I created a UserControl called MyFrame, which would host all the pages. In my App.xaml.cs I have the following to make sure that MyFrame is loaded when the App loads: private void Application_Startup(object sender, StartupEventArgs e) { this.RootVisual = new MyFrame(); } My UriMapper class resides in App.xaml and looks like the following: <navcore:UriMapper x:Key="uriMapper"> <navcore:UriMapping Uri="Login" MappedUri="Login.xaml"> </navcore:UriMapper> Within my 'MyFrame' class, I have the following <StackPanel Orientation="Horizontal"> <StackPanel Orientation="Vertical"> <HyperlinkButton Tag="Login" Content="Login" Click="HyperlinkButton_Click" /> </StackPanel> <StackPanel Orientation="Vertical"> <navigation:Frame x:Name="ContentFrame" Style="{StaticResource ContentFrameStyle}" /> </StackPanel> </StackPanel> And within the callback for my HyperlinkButton's event handler, I have the following: private void HyperlinkButton_Click(object sender, RoutedEventArgs e) { ContentFrame.Navigate(new Uri((sender as HyperlinkButton).Tag.ToString(), UriKind.Relative)); } The Login.xaml file is in my root folder (right under Project). This navigation does not seem to work! The exception I get reads like so: Navigation is only supported to relative URIs that are fragments, or begin with '/', or which contain ';component/'. Parameter name: uri The Login page does not load. There is no problem with Login.xaml as when I set this.RootVisual = new Login(); the page loads just fine. I also tried setting the NavigateUri attribute of the HyperlinkButton to "Login." No cigar. I'll appreciate any help! Thanks a lot in advance

  • PostgreSQL: Rolling back a transaction within a plpgsql function?

    - by jamieb
    Coming from the MS SQL world, I tend to make heavy use of stored procedures. I'm currently writing an application uses a lot of PostgreSQL plpgsql functions. What I'd like to do is rollback all INSERTS/UPDATES contained within a particular function if I get an exception at any point within it. I was originally under the impression that each function is wrapped in it's own transaction and that an exception would automatically rollback everything. However, that doesn't seem to be the case. I'm wondering if I ought to be using savepoints in combination with exception handling instead? But I don't really understand the difference between a transaction and a savepoint to know if this is the best approach. Any advice please? CREATE OR REPLACE FUNCTION do_something( _an_input_var int ) RETURNS bool AS $$ DECLARE _a_variable int; BEGIN INSERT INTO tableA (col1, col2, col3) VALUES (0, 1, 2); INSERT INTO tableB (col1, col2, col3); VALUES (0, 1, 'whoops! not an integer'); -- The exception will cause the function to bomb, but the values -- inserted into "tableA" are not rolled back. RETURN True; END; $$ LANGUAGE plpgsql;
