  • How to draw a texture to a MS Terrain object - Farseer

    - by Brad
    I'm using Farseer to make a game in XNA and I can't seem to figure this out. I've decided to use MSTerrain for making my game's terrain because I wanted destructible terrain and MSTerrain seemed like the best bet. Unfortunately, I'm stumped on how to actually show the terrain. When I generate the terrain it's visible in debug view, but MSTerrain does not have a Draw method, so I'm wondering how it is supposed to be drawn to the screen? Is it worth pursuing? I'm starting to think that MSTerrain is more trouble than it's worth, is there another better way to do this with bodies? I appreciate any help you can give. Thanks.

  • regular expression to insert space beetween thousands and hundreds...

    - by pixelboy
    Regular expressions and I aren't quite good friends. So here's the really basic operation i'm trying to do using javascript (jQuery framwork that is). My calculation function return a number, unformated, and i'd like to separate thousands and hundreds by a white space ' '. I'm sure it's pretty easy for a regexp regular user... but for me... Thanks for the help.

  • Java Regular Expression. Check if String contains ONLY Letters

    - by user69514
    How do I check if a String contains only letters in java? I want to write an if statement that will return false if there is a white space, a number, a symbol or anything else other than a-z A-Z. My string must contain ONLY letters. I thought I could do it this way, but I'm doing it wrong: if( ereg("[a-zA-Z]+", $myString)) return true; else return false;

  • Can i have a negative value as constant expression in Scala?

    - by Klinke
    I have an Java-Annotation that return a double value: @Retention(RetentionPolicy.RUNTIME) @Target(ElementType.FIELD) public @interface DoubleValue { double value(); } When i try to attach the annotation to a field in a scala class and the value is negativ like here: class Test { @DoubleValue(-0.05) var a = _ } i get an compiler error with the message: "annotation argument needs to be a constant; found: 0.05.unary_-". I understood that i need a numerical literal and i looked into the Scala Language Specification and it seems, that the - sign is only used for the exponent but not for the mantissa. Does someone has an idea how i can have a negative value as runtime information using annotations? Thanks, Klinke

  • MS SQL : Can you help me with this query?

    - by rlb.usa
    I want to run a diagnostic report on our MS SQL 2008 database server. I am looping through all of the databases, and then for each database, I want to look at each table. But, when I go to look at each table (with tbl_cursor), it always picks up the tables in the database 'master'. I think it's because of my tbl_cursor selection : SELECT table_name FROM information_schema.tables WHERE table_type = 'base table' How do I fix this? Here's the entire code: SET NOCOUNT ON DECLARE @table_count INT DECLARE @db_cursor VARCHAR(100) DECLARE database_cursor CURSOR FOR SELECT name FROM sys.databases where name<>N'master' OPEN database_cursor FETCH NEXT FROM database_cursor INTO @db_cursor WHILE @@Fetch_status = 0 BEGIN PRINT @db_cursor SET @table_count = 0 DECLARE @table_cursor VARCHAR(100) DECLARE tbl_cursor CURSOR FOR SELECT table_name FROM information_schema.tables WHERE table_type = 'base table' OPEN tbl_cursor FETCH NEXT FROM tbl_cursor INTO @table_cursor WHILE @@Fetch_status = 0 BEGIN DECLARE @table_cmd NVARCHAR(255) SET @table_cmd = N'IF NOT EXISTS( SELECT TOP(1) * FROM ' + @table_cursor + ') PRINT N'' Table ''''' + @table_cursor + ''''' is empty'' ' --PRINT @table_cmd --debug EXEC sp_executesql @table_cmd SET @table_count = @table_count + 1 FETCH NEXT FROM tbl_cursor INTO @table_cursor END CLOSE tbl_cursor DEALLOCATE tbl_cursor PRINT @db_cursor + N' Total Tables : ' + CAST( @table_count as varchar(2) ) PRINT N'' -- print another blank line SET @table_count = 0 FETCH NEXT FROM database_cursor INTO @db_cursor END CLOSE database_cursor DEALLOCATE database_cursor SET NOCOUNT OFF

  • How can you connect to a password protected MS Access Database from a Spring JdbcTemplate?

    - by Tim Visher
    I need to connect to a password protected MS Access 2003 DB using the JDBC-ODBC bridge. I can't find out how to specify the password in the connect string, or even if that is the correct method of connecting. It would probably be relevant to mention that this is a Spring App which is accessing the database through a JdbcTemplate configured as a datasource bean in our application context file. Some relevant snippets: from application-context.xml <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate"> <property name="dataSource" ref="legacyDataSource" /> </bean> <bean id="jobsheetLocation" class="java.lang.String"> <constructor-arg value="${jobsheet.location}"/> </bean> <bean id="legacyDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="${jdbc.legacy.driverClassName}" /> <property name="url" value="${jdbc.legacy.url}"/> <property name="password" value="-------------" /> </bean> from our build properties jdbc.legacy.driverClassName=sun.jdbc.odbc.JdbcOdbcDriver jdbc.legacy.url=jdbc:odbc:Driver\={Microsoft Access Driver (*.mdb)};Dbq\=@LegacyDbPath@;DriverID\=22;READONLY\=true Any thoughts?

  • configure a Cisco ASA to use MS-CHAP v2 for RADIUS authentication

    - by DrStalker
    Cisco ASA5505 8.2(2) Windows 2003 AD server We want to configure our ASA (10.1.1.1) to authenticate remote VPN users through RADIUS on the Windows AD controller (10.1.1.200) We have the following entry on the ASA: aaa-server SYSCON-RADIUS protocol radius aaa-server SYSCON-RADIUS (inside) host 10.1.1.200 key ***** radius-common-pw ***** When I test a login using the account COMPANY\username I see the users credentials are correct in the security log, but I get the following in the windows system logs: User COMPANY\myusername was denied access. Fully-Qualified-User-Name = company.com/CorpUsers/AU/My Name NAS-IP-Address = 10.1.1.1 NAS-Identifier = <not present> Called-Station-Identifier = <not present> Calling-Station-Identifier = <not present> Client-Friendly-Name = ASA5510 Client-IP-Address = 10.1.1.1 NAS-Port-Type = Virtual NAS-Port = 7 Proxy-Policy-Name = Use Windows authentication for all users Authentication-Provider = Windows Authentication-Server = <undetermined> Policy-Name = VPN Authentication Authentication-Type = PAP EAP-Type = <undetermined> Reason-Code = 66 Reason = The user attempted to use an authentication method that is not enabled on the matching remote access policy. My assumption is that the ASA is using PAP authentication, instead of MS-CHAP v2; the credentials are confirmed, the proper Remote Access Policy is being used, but this policy is set to only allow MS-CHAP2. What do we need to do on the ASA to make it us MS-CHAP v2? In the ADSM GUI The "Microsoft CHAP v2 compatible" tickbox is enabled, but I don't know what this corresponds to in the config.

  • MS SQL to MySQL using MySQL Migration Toolkit: permission issue

    - by Zeno
    I have a MS SQL imported into SQL Server 2008 from a .bak and I set it to Mixed mode. I have a SQL user (called "test") that can correctly access the database using SQL Server. I need to convert this to a MySQL database, so I got the MySQL Migration Toolkit. I pick "MS SQL Server" and then it asks for the hostname/username/password/database. I'm not 100% sure on these, but I used "localhost" (running on same computer), left the port as is (1433) and the username/password ("test") for the SQL Server. And I used the database name for the SQL Server database I'm looking to import. I clicked next, enter my MySQL database details and then attempt to run it and I get this error: Connecting to source database and retrieve schemata names. Initializing JDBC driver ... Driver class MS SQL JDBC Driver Opening connection ...

  • Slow Windows Explorer on Windows 7

    - by MadBoy
    I have Laptop with i7 (4 cores), 8GB ram and SSD OCZ Vertex 3 MaxIOPS which in testing that I did just now does 400mb/s+ read/write. However the responsiveness of Windows Explorer is far from being perfect. Opening up Computer, Documents, going into folders is very slow (1-5seconds). I don't have any viruses or spyware and I have tried changing properties to optimize view for General Items. I tried disabling Search Indexer but it made search in Outlook 2010 crawl and didn't bring any other effect. Even double clicking on file takes some time to open things up (like clicking a Word document). I don't have any drives mapped, my computer is not joined to domain. I have multiple VPN connections that I connect to but they all have disabled default gateways. I tried using CC Cleaner or some Windows 7 Tweaks app to disable some things. I am power user using Visual Studio, Tortoise SVN and other developer/administration apps. Any non obvious ideas? Edit: So I've been trying to pinpoint where the issue comes from and it seems that straight after reboot Windows Explorer opens very fast, when I load 3-4 programs (Royal TS, Visual Studio, Outlook) it's noticeably slower and the more programs I have it gets worse. After I start closing programs it starts working better and if I leave 2 open it's fast again. I tried doing some research with DiskMon and other programs from sysinternals but couldn't find anything suspicious. Below are stats during normal usage with a lots of programs open: - Ram usage with a lot of programs open and no swap file (i disabled it for testing): 6.95GB - CPU usage: 15%, none of the cores takes more then 50% (I have VS 2010 open x 4) HD Tune Pro: OCZ-VERTEX3 MI Benchmark Test capacity: full Read transfer rate Transfer Rate Minimum : 363.9 MB/s Transfer Rate Maximum : 505.5 MB/s Transfer Rate Average : Access Time : Burst Rate : CPU Usage : HD Tune Pro: OCZ-VERTEX3 MI File Benchmark Drive C: Transfer rate test File Size: 500 MB Sequential read 484102 KB/s Sequential write 444714 KB/s Random read 7779 IOPS Random write 16888 IOPS Random read (queue depth = 32) 73007 IOPS Random write (queue depth = 32) 69790 IOPS HD Tune Pro: OCZ-VERTEX3 MI Random Access Test capacity: full Read test Transfer size operations / sec avg. access time max. access time avg. speed 512 bytes 3260 IOPS 0.306 ms 2.106 ms 1.592 MB/s 4 KB 4161 IOPS 0.240 ms 2.006 ms 16.256 MB/s 64 KB 2382 IOPS 0.419 ms 2.367 ms 148.934 MB/s 1 MB 449 IOPS 2.225 ms 4.197 ms 449.407 MB/s Random 809 IOPS 1.235 ms 6.551 ms 410.527 MB/s HD Tune Pro: OCZ-VERTEX3 MI Extra Tests Test capacity: full Random seek 3975 IOPS 0.252 ms 1.941 MB/s Random seek 4 KB 4245 IOPS 0.236 ms 16.583 MB/s Butterfly seek 4086 IOPS 0.245 ms 1.995 MB/s Random seek / size 64 KB 3812 IOPS 0.262 ms 58.606 MB/s Random seek / size 8 MB 120 IOPS 8.348 ms 485.737 MB/s Sequential outer 4524 IOPS 0.221 ms 282.721 MB/s Sequential middle 4429 IOPS 0.226 ms 276.818 MB/s Sequential inner 5504 IOPS 0.182 ms 344.000 MB/s Burst rate 4472 IOPS 0.224 ms 279.475 MB/s

  • Any Application to bind various documents

    - by Codeslayer
    I communicate with the client using various tools such as MS Outlook,Mailing through Google/ Yahoo accounts, sending Word or Excel documents as attachments through this mail. What I am looking at is there any tool which will help me in binding all these documents so that I may be able to virtually bind all these documents of a particular client. For example all these documents were sent to Client A 2 Outlook mails without attachment 2 Web mails with MS-Word attachment 1 Web Mail with Excel attachment Now I wish I had a document which would bind the Outlook mail bodies as text files MS-Word documents Excel document Previous versions of MS-Office had Office Binder. Is there something similar to this Thanx.

  • Preg Expression to identify classes/ids in a CSS file that have no contents

    - by dclowd9901
    I'm in the process of updating some old CSS files in our systems, and we have a bunch that have lots of empty classes simply taking up space in the file. I'd love to learn how to write Regular expressions, but I just don't get them. I'm hoping the more I expose myself to them (with a little more cohesive explanation), the more I'll end up understanding them. The Problem That said, I'm looking for an expression that will identify text followed by a '{' (some have spaces in between, and some do not) and if there are no letters or numbers between that bracket and '}' (spaces don't count), it will be identified as a matching string. I suppose I can trim the whitespace out of the doc before I run a regular expression through it, but I don't want to change the basic structure of the text. I'm hoping to return it into a large <textarea>. Bonus points for explaining the characters and their meanings, and also an expression identifying lines in the copy without any text or numbers, as well. I will likely use the final expression in PHP script. tl;dr: Regular Expression to match: .a_class_or #an_id { /* if there aren't any alphanumerics in here, this should be a matching line of text */ }

  • Visual Studio expression containing a term named "by" cannot be evaluated in the watch window

    - by Andrei Pana
    Consider my C++ code below: int _tmain(int argc, _TCHAR* argv[]) { int by = 10; printf("%d\n", by); int bx = 20; printf("%d\n", (by + bx)); return 0; } which works fine. The funny thing is with the "by" variable. If I try to add a watch for a simple expression that contains by, the result will be CXX0030: Error: expression cannot be evaluated. For example, on a breakpoint on return 0, if I add the following watches I get the results mentioned: by : 10 bx : 20 by + 5 : CXX0030: Error: expression cannot be evaluated bx + 5 : 25 by + bx : CXX0030: Error: expression cannot be evaluated (by) + bx : 30 by + (bx) : CXX0030: Error: expression cannot be evaluated bx + (by) : CXX0014: Error: missing operrand This happens on VS2010, VS2008 on multiple computers. So, more out of curiosity, what is happening with "by"? Is it some kind of strange operator? Why doesn't bx get the same treatment? (I've tried google on this but it is quite difficult to get some relevant hits with terms like "by")

  • Determining whether values can potentially match a regular expression, given more input

    - by Andreas Grech
    I am currently writing an application in JavaScript where I'm matching input to regular expressions, but I also need to find a way how to match strings to parts of the regular expressions. For example: var invalid = "x", potentially = "g", valid = "ggg", gReg = /^ggg$/; gReg.test(invalid); //returns false (correct) gReg.test(valid); //returns true (correct) Now I need to find a way to somehow determine that the value of the potentially variable doesn't exactly match the /^ggg$/ expression, BUT with more input, it potentially can! So for example in this case, the potentially variable is g, but if two more g's are appended to it, it will match the regular expression /^ggg$/ But in the case of invalid, it can never match the /^ggg$/ expression, no matter how many characters you append to it. So how can I determine if a string has or doesn't have potential to match a particular regular expression?

  • Help with Linq Expression - INotifyPropertyChanged

    - by Stephen Patten
    Hello, I'm reading the source code from the latest Prism 4 drop and am interested in solving this problem. There is a base class for the ViewModels that implements INotifyPropertyChanged and INotifyDataErrorInfo and provides some refactoring friendly change notification. protected void RaisePropertyChanged<T>(Expression<Func<T>> propertyExpresssion) { var propertyName = ExtractPropertyName(propertyExpresssion); this.RaisePropertyChanged(propertyName); } private string ExtractPropertyName<T>(Expression<Func<T>> propertyExpresssion) { if (propertyExpresssion == null) { throw new ArgumentNullException("propertyExpression"); } var memberExpression = propertyExpresssion.Body as MemberExpression; if (memberExpression == null) { throw new ArgumentException("The expression is not a member access expression.", "propertyExpression"); } var property = memberExpression.Member as PropertyInfo; if (property == null) { throw new ArgumentException("The member access expression does not access property.","propertyExpression"); } if (!property.DeclaringType.IsAssignableFrom(this.GetType())) { throw new ArgumentException("The referenced property belongs to a different type.", "propertyExpression"); } var getMethod = property.GetGetMethod(true); if (getMethod == null) { // this shouldn't happen - the expression would reject the property before reaching this far throw new ArgumentException("The referenced property does not have a get method.", "propertyExpression"); } if (getMethod.IsStatic) { throw new ArgumentException("The referenced property is a static property.", "propertyExpression"); } return memberExpression.Member.Name; } and as an example of it's usage private void RetrieveNewQuestionnaire() { this.Questions.Clear(); var template = this.questionnaireService.GetQuestionnaireTemplate(); this.questionnaire = new Questionnaire(template); foreach (var question in this.questionnaire.Questions) { this.Questions.Add(this.CreateQuestionViewModel(question)); } this.RaisePropertyChanged(() => this.Name); this.RaisePropertyChanged(() => this.UnansweredQuestions); this.RaisePropertyChanged(() => this.TotalQuestions); this.RaisePropertyChanged(() => this.CanSubmit); } My question is this. What would it take to pass an array of the property names to an overloaded method (RaisePropertyChanged) and condense this last bit of code from 4 lines to 1? Thank you, Stephen

  • What is the regular expression for valdating a 'price' in a jtextfield

    - by wniroshan
    I want to validate a jtextfield as user inputs a price of some item. I have a perfectly working code which beeps and discard if user inputs some character that doesnt match the regular expression.(for regular expression "[0-9]+" it accepts any number of digits and beeps if a letter is given as input) But the problem is I want to validate an input like "12500.00". Format should be any number of digits before decimal point and two digits after the decimal point. eg: ddd.dd I tried the following regular expression. But the i doesnt allow user to input "." character. It allows user to input any number of digits but when "." key is pressed input is not accepted. here is the regular expression I used. "[0-9]+ | [0-9]+. | [0-9]+.[0-9]{1} | [0-9]+{2}" important: user input is validated character by character as the user inputs them to the jtextfield.
