• VS 2008 SP1 text editor flickering over remote desktop connection

  - by AltairDusk

  I am connecting from a Windows 7 x64 machine to my dev machine running Windows XP SP3 using the built in remote desktop client. For most apps it works fine with no problems, for Visual Studio whenever I am typing the entire text editor keeps redrawing. I stumbled across this question: http://stackoverflow.com/questions/873849/vs-2008-sp1-over-remote-desktop-constant-repainting and I have tried all of the suggestions in it to no effect, including resetting all VS settings back to default then disabling the suggested settings. Has anyone found a reliable solution to this? I feel like I'm going insane with the screen constantly refreshing when I'm working from home. Some additional information: Remote Desktop is set to run at 1680x1050, 15bit color, Low-speed broadband for the experience setting with all but Visual styles and Persistent bitmap caching unchecked. Visual Studio 2008 Team System is running on the dev machine with Service Pack 1 and Power Commands installed.

• Is there a way to have customised text instead of subject in Thunderbird's inbox list?

  - by peterp

  I am getting a lot of informational emails like "You've got a new message from ..." or "Notification of Donation Received", which often do not contain any information in the subject so that I have to open the email to see who sent the message or who donated which amount. I'd love to be able to make TB parse incoming emails and then display something interesting instead of the original subject, e.g. by defining a regular expression pattern. I know how to write regular expressions, but I do not know whether there is a way or an addon to modify the displayed text in the messages view. EDIT for clarification: I would like donation notifications from Paypal not to be displayed as original Notification of Donation Received but rather Paypal: John Doe has donated 50$

• How can I do an "insert" statement from MS SQL -> MYSQL using linked servers

  - by bvandrunen

  Is it possible to do an "insert" statement through linked servers. I know it is possible by using MSDTC...but does this work between MS SQL and MYSQL? Any help would be greatly appreciated. As of right now...I can update and select between the 2 databases but it gives me an error when I try to run an insert statement. OLE DB provider "MSDASQL" for linked server "******" returned message "Query-based insertion or updating of BLOB values is not supported.". Msg 7343, Level 16, State 2, Line 1 The OLE DB provider "MSDASQL" for linked server "******" could not INSERT INTO table "[*********]...[******_options]".

• JDBC CallableStatement and Oracle SYS_REFCURSOR IN parameters?

  - by deebo

  Pretty much what it says in the title, how the hell is this supposed to be done? Basically i need to pass a null (empty?) ref cursor as an IN parameter to a stored procedure. /** spring's PreparedStatementSetter#setValues(...) */ public void setValues(PreparedStatement ps) throws SQLException { CallableStatement cs = (CallableStatement) ps; cs.setString(1,"constant"); //this is the IN param cs.setNull(2, OracleTypes.CURSOR); //this is the OUT param cs.registerOutParameter(3, OracleTypes.CURSOR); } And this fails with: caused by: java.sql.SQLException: Unsupported feature: sqlType=-10 at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112) at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:146) at oracle.jdbc.driver.OraclePreparedStatement.setNullCritical(OraclePreparedStatement.java:4399) at oracle.jdbc.driver.OraclePreparedStatement.setNullInternal(OraclePreparedStatement.java:4161) at oracle.jdbc.driver.OracleCallableStatement.setNull(OracleCallableStatement.java:4472) I'm at a loss here, tried several different ways to do this, but I couldn't find any examples about this and have no idea how to do it properly.

• How do I set ORDER BY params using prepated PDO statement?

  - by Marlorn

  I'm having problems using params in the ORDER BY section of my SQL. It doesn't issue any warnings, but prints out nothing. $order = 'columnName'; $direction = 'ASC'; $stmt = $db->prepare("SELECT field from table WHERE column = :my_param ORDER BY :order :direction"); $stmt->bindParam(':my_param', $is_live, PDO::PARAM_STR); $stmt->bindParam(':order', $order, PDO::PARAM_STR); $stmt->bindParam(':direction', $direction, PDO::PARAM_STR); $stmt->execute(); The :my_param works, but not :order or :direction. Is it not being internally escaped correctly? Am I stuck inserting it directly in the SQL? Like so: $order = 'columnName'; $direction = 'ASC'; $stmt = $db->prepare("SELECT * from table WHERE is_live = :is_live ORDER BY $order $direction"); Is there a PDO::PARAM_COLUMN_NAME constant or some equivalent? Thanks!

• Matlab: how do I force ode45 to take steps of exactly 0.01 on the T axis?

  - by Gravitas

  I'm using Matlab to solve a differential equation. I want to force ode45 to take constant steps, so it always increments 0.01 on the T axis while solving the equation. How do I do this? ode45 is consistently taking optimized, random steps, and I can't seem to work out how to make it take consistent, small steps of 0.01. Here is the code: options= odeset('Reltol',0.001,'Stats','on'); %figure(1); %clf; init=[xo yo zo]'; tspan=[to tf]; %tspan = t0:0.01:tf; [T,Y]=ode45(name,tspan,init,options);

• Why is a fixed size buffers (arrays) must be unsafe?

  - by brickner

  Let's say I want to have a value type of 7 bytes (or 3 or 777). I can define it like that: public struct Buffer71 { public byte b0; public byte b1; public byte b2; public byte b3; public byte b4; public byte b5; public byte b6; } A simpler way to define it is using a fixed buffer public struct Buffer72 { public unsafe fixed byte bs[7]; } Of course the second definition is simpler. The problem lies with the unsafe keyword that must be provided for fixed buffers. I understand that this is implemented using pointers and hence unsafe. My question is why does it have to be unsafe? Why can't C# provide arbitrary constant length arrays and keep them as a value type instead of making it a C# reference type array or unsafe buffers?

• Is there a best-practice approach for internationalization of an application?

  - by Lee Warner

  We need to have our apps be translated into other languages. This entails renaming the .text properties of our visible controls as well as other literals found within our apps to whatever language we need to translate into. Is this something that can easily be accomplished with .resx files? I was thinking of creating a master resx key/value list where the key would be the fully qualified name of the control/variable/constant etc. and then refactor our apps to look into this file to get their values based on the cultureinfo found at runtime? Is there a standard or simpler approach to this problem?

• Microsoft Visual C++ Runtime error when viewing JPEG files in Explorer

  - by Prince Kitts

  I am getting the following error each time I view JPG files in the windows explorer in Detailed view. Microsoft Visual C++ Runtime Library Assertion failed! Program: C:\Windows\Explorer.EXE File: multimedia\photos\metadatahandler\util.cpp Line: 4706 Expression: MinutesFraction < 1.0 For information on how your program can cause an assertion failure, see the Visual C++ documentation on asserts (Press Retry to debug the application - JIT must be enabled) These pictures were taken from a Nikon Coolpix AW110 camera. I think it is related to some EXIF data that is a date/time. I have tried reinstalling the Visual C++ 2013 and 2008 Run time library and restarting and the problem is still there.

  I need a hidden input to contain the value passed by the querystring via a JSP's URL. The URL looks like... http://nowhere.com/myapp/blah.jsp?key=12345 The JSP looks like... <html> <body> <input id="key" type="hidden" value="<%=request.getParameter('key')%>" /> </body> </html> This causes a 500 error...

• Data structure in c for fast look-up/insertion/removal of integers (from a known finite domain)

  - by MrDatabase

  I'm writing a mobile phone based game in c. I'm interested in a data structure that supports fast (amortized O(1) if possible) insertion, look-up, and removal. The data structure will store integers from the domain [0, n] where n is known ahead of time (it's a constant) and n is relatively small (on the order of 100000). So far I've considered an array of integers where the "ith" bit is set iff the "ith" integer is contained in the set (so a[0] is integers 0 through 31, a[1] is integers 32 through 63 etc). Is there an easier way to do this in c?

• jQuery hover function

  - by Daniel Hertz

  So I have a hover function that is supposed to move an arrow under the corrent the link that someone hovers over. The problem is, the arrow never returns to the current link when the person stops hovering over the link. However, if I set the left properly with a constant value it works. Anyone have any ideas? var currentId = '#' + $('body').attr('id') + '_link'; var xCordCurrent = $(currentId).offset().left - ($('#arrow').width() / 2); var xCordHover = $(event.target).offset().left + ($(event.target).width() / 2) - ($('#arrow').width() / 2); $('#arrow').animate( { left: xCordHover }, { duration: 'slow', easing: 'easeOutBack' }) }, function(event) { $('#arrow').animate( { left: xCordCurrent }, { duration: 'slow', easing: 'easeOutBack' }) });

• Is Stopwatch really broken?

  - by Jakub Šturc

  At MSDN page for Stopwatch class I discovered link to interesting article which makes following statement about Stopwatch: However there are some serious issues: This can be unreliable on a PC with multiple processors. Due to a bug in the BIOS, Start() and Stop() must be executed on the same processor to get a correct result. This is unreliable on processors that do not have a constant clock speed (most processors can reduce the clock speed to conserve energy). This is explained in detail here. I am little confused. I've seen tons of examples of using Stopwatch and nobody mention this drawbacks. How serious is this? Should I avoid using Stopwatch?

• How to set JtextArea to keep fixed no of rows?

  - by Hippo

  How can i keep no of rows constant in text area. I need to create a console window for my application. If rows exceeds predefined no of rows first rows must get disposed. As if first written row will be destroyed first when i append anything which exceeds no of rows set. One more thing , i need to keep vertical scroll bar. That means no of rows must not be the whatever rows are visible when text area it opened. For example : - no of visible rows on view port are 30. It should keep 120 rows information, which will can be seen with the help of scroll bar.

• B-Tree Revision

  - by stan

  Hi, If we are looking for line intersections (horizontal and vertical lines only) and we have n lines with half of them vertical and no intersections then Sorting the list of line end points on y value will take N log N using mergesort Each insert delete and search of our data structue (assuming its a b-tree) will be < log n so the total search time will be N log N What am i missing here, if the time to sort using mergesort takes a time of N log N and insert and delete takes a time of < log n are we dropping the constant factor to give an overal time of N log N. If not then how comes < log n goes missing in total ONotation run time? Thanks

• How to sort in-place using the merge sort algorithm?

  - by eSKay

  I know the question is too open. All I want is someone to tell me how to convert a normal merge sort into an in-place merge sort (or a merge sort with constant extra space overhead). All I can find (on the net) is pages saying "it is too complex" or "out of scope of this text". "The only known ways to merge in-place (without any extra space) are too complex to be reduced to practical program." (from here) Even if it is too complex, can somebody outline the basic concept of how to make the merge sort in-place?

• Can I configure NUnit so that Debug.Fail doesn't show a message box when I run my tests?

  - by panamack

  I have this property: public SubjectStatus Status { get { return status; } set { if (Enum.IsDefined(typeof(SubjectStatus), value)) { status = value; } else { Debug.Fail("Error setting Subject.Status", "There is no SubjectStatus enum constant defined for that value."); return; } } } and this unit test [Test] public void StatusProperty_StatusChangedToValueWithoutEnumDefinition_StatusUnchanged() { Subject subject = new TestSubjectImp("1"); // assigned by casting from an int to a defined value subject.Status = (SubjectStatus)2; Assert.AreEqual(SubjectStatus.Completed, subject.Status); // assigned by casting from an int to an undefined value subject.Status = (SubjectStatus)100; // no change to previous value Assert.AreEqual(SubjectStatus.Completed, subject.Status); } Is there a way I can prevent Debug.Fail displaying a message box when I run my tests, but allow it to show me one when I debug my application?

• Source Insight: Show me Enum Values

  - by JXG

  I'm programming in C and using Source Insight. I have an enum type with a lot of constants (like 100). I have debug prints that print out variable values, but they (of course) print out as integers. What I'd like to do is click on the name of an enum constant, and see its numeric value displayed somewhere. (I've seen this done in a Visual Studio plugin, so it must be possible.) That is, assume I have enum colors { ORANGE, PURPLE, PINK }; I want to click on (or select, or something) PURPLE and see the value 1 somewhere visible (ideally, the symbol window or context window, but I'm not particular). Is there an easy way to do this in Source Insight? Is there a difficult way, at least (such as writing a macro)?

• How to ignore CDATA tags?

  - by Petre

  I'm trying to make an html parser, but when I load the html I get warnings like this Warning: DOMDocument::loadHTML() [domdocument.loadhtml]: Invalid char in CDATA 0x1C in Entity, line: 1302 Here is the code I use class Parser { public $url=null; public $html=null; public $tidy=null; public $head=null; public $head_xpath=null; function __construct($url){ $this->url=$url; $this->html=file_get_contents($this->url); $this->tidy=tidy_parse_string($this->html); $this->head=new DOMDocument(); $this->head->loadHTML($this->tidy->head()); $this->head_xpath= new DOMXPath($this->head); } } $x=new Parser("http://www.guardian.co.uk/politics/2012/mar/24/vince-cable-coalition-banking-row"); I searched around and found the LIBXML_NOCDATA constant, but I don't know how to set it. So how could i completely ignore CDATA?

• Objective C - Constants with behaviour

  - by Akshay

  Hi, I'm new to Objective C. I am trying to define Constants which have behavior associated with them. So far I have done - @interface Direction : NSObject { NSString *displayName; } -(id)initWithDisplayName:(NSString *)aName; -(id)left; // returns West when North -(id)right; // return East when North @end @implementation Direction -(id)initWithDisplayName:(NSString *)aName { if(self = [super init]) { displayName = aName; } return self; } -(id)left {}; -(id)right {}; @end Direction* North = [Direction initWithDisplayName:@"North"]; // error - initializer element is not constant. This approach results in the indicated error. Is there a better way of doing this in Objective C.

• How to define enum in as3?

  - by Nava Carmon

  Is there a way to define an enum in AS3 in a way we do it in other languages? I can define constants with defined values like that: private const CONST_1:int = 0; private const CONST_2:int = 1; private const CONST_3:int = 2; and so on. If I want to insert some other constant between 3 these I need to move all values like that: private const CONST_1:int = 0; private const CONST_2:int = 1; private const CONST_2A:int = 2; private const CONST_3:int = 3; while in other language I would end up with only adding a new member to enum closure like that: enum { CONST_1 = 0, CONST_2, CONST_2A, CONST_3 } MyConstEnum; Does AS3 has something similar? Thanks

• Why doesn't GCC produce a warning when assigning a signed literal to an unsigned type?

  - by maerics

  Several questions on this website reveal pitfalls when mixing signed and unsigned types and most compilers seem to do a good job about generating warnings of this type. However, GCC doesn't seem to care when assigning a signed constant to an unsigned type! Consider the following program: /* foo.c */ #include <stdio.h> int main(void) { unsigned int x=20, y=-30; if (x > y) { printf("%d > %d\n", x, y); } else { printf("%d <= %d\n", x, y); } return 0; } Compilation with GCC 4.2.1 as below produces no output on the console: gcc -Werror -Wall -Wextra -pedantic foo.c -o foo The resulting executable generates the following output: $ ./foo 20 <= -30 Is there some reason that GCC doesn't generate any warning or error message when assigning the signed value -30 to the unsigned integer variable y?

The part that is confusing me is that ASP.ASP_AIRSPACE_NM is being right joined to a constant.
