  • ASP.NET variable scope

    - by c11ada
    hey all, im really new to ASP.Net and still havnt got my head round most of the concepts, im really having problems with variable, when creating a desktop application, any variable created in code for example int n = 10; this variable will be there until the program is running right. but in asp iv created variables which are supposed to last until the user gets of that page, so for example say i have a page which takes the users value ( call this variable n say the user type in 10) and every time the user presses the next button the code add 10 to this value. so the first time the user presses the next button n= n + 10; what i have found is no matter how many times i press the next button n will always equal 20, because the previous value is not saved !! these values are populated the first time the user enters that page, once the user clicks the next button the content of these values disappear! how can stop this from happening ?? hope this makes sense !! thanks

  • Biztalk - local variable in expression shape

    - by Jeremy Stein
    Sometimes when I'm writing XLANG/s code in an expression shape, it would be more readable if I could just use a temporary variable within the scope of that one code block. I hate to clutter up the entire orchestration with a variable declaration. Is there a way to declare a variable within an expression shape?

  • check date for variable value

    - by Leslie
    I have a variable in my Java class that needs to be set based on whether today is before or after 7/1. If today is before 7/1 then we are in fiscal year that is the current year (so today we are in FY10). If today is after 7/1 our new fiscal year has started and the variable needs to be the next year (so FY11). psuedo code: if today < 7/1/anyyear then BudgetCode = "1" + thisYear(YY) //variable will be 110 else BudgetCode = "1" + nextYear(YY) //variable will be 111 thanks!

  • NS2, Otcl: using a variable of an owned instance within a class

    - by Hussain
    Hello all, I'm using NS2 to create some new classes in C++ and then link them to otcl. The linkage and everything works, but when I try to use the otcl variables in an object, I'm having a trouble. For example, suppose I have a class "Node" with the variable X. In the code I want to set this value and later on use it in some if-statements. Setting the variable is no problem using this code: $node1 set x 4 Now the problem I'm having is when I try to use this variable x anywhere. In C++ we could use a general variable (i.e. y) and say "y=node.x and then use y in some if-statements. I have tried to look for a method to perform the same thing in otcl, but failed. Any help is appriciated. Thanks in Advance.

  • Stored Procedure: Variable passed from PHP alters second half of query string

    - by Stephanie
    Hello everyone, Basically, we have an ASP website right now that I'm converting to PHP. We're still using the MSSQL server for the DB -- it's not moving. In the ASP, now, there's an include file with a giant sql query that's being executed. This include sits on a lot of pages and this is a simple version of what happens. Pages A, B and C all use this include file to return a listing. In ASP, Page A passes through variable A to the include file - page B passes through variable B -- page C passes through variable C, and so on. The include file builds the SQL query like this: sql = "SELECT * from table_one LEFT OUTER JOIN table_two ON table_one.id = table_two.id" then adds (remember, ASP), based on the variable passed through from the parent page, Select Case sType Case "A" sql = sql & "WHERE LOWER(column_a) <> 'no' AND LTRIM(ISNULL(column_b),'') <> '' ORDER BY column_a Case "B" sql = sql & "WHERE LOWER(column_c) <> 'no' ORDER BY lastname, firstname Case "C" sql = sql & "WHERE LOWER(column_f) <> 'no' OR LOWER(column_g) <> 'no' ORDER BY column_g As you notice, every string that's added on as the second part of the sql query is different than the previous; not just one variable can be substituted out, which is what has me stumped. How do I translate this case / switch into the stored procedure, based on the varchar input that I pass to the stored procedure via PHP? This stored procedure will actually handle a query listing for about 20 pages, so it's a hefty one and this is my first major complicated one. I'm getting there, though! I'm also just more used to MySQL, too. Not that they're that different. :P Thank you very much for your help in advance. Stephanie

  • htaccess - rewrite rule issue - not able to get 10th variable

    - by sandeepan-nath
    I am not able to get the 10th variable. I am getting 1st variable appended with a 0(zero) instead.

I read in many places about this thing. Here http://www.digimantra.com/tutorials/advanced-htaccess-for-more-than-10-group-of-backtrack-references/, they have given a workaround for the problem - using %1 instead of $10, but that too is not working. Please help. I am completely blocked.

  • best practice on precedence of variable declaration and error handling in C

    - by guest
    is there an advantage in one of the following two approaches over the other? here it is first tested, whether fopen succeeds at all and then all the variable declarations take place, to ensure they are not carried out, since they mustn't have had to void func(void) { FILE *fd; if ((fd = fopen("blafoo", "+r")) == NULL ) { fprintf(stderr, "fopen() failed\n"); exit(EXIT_FAILURE); } int a, b, c; float d, e, f; /* variable declarations */ /* remaining code */ } this is just the opposite. all variable declarations take place, even if fopen fails void func(void) { FILE *fd; int a, b, c; float d, e, f; /* variable declarations */ if ((fd = fopen("blafoo", "+r")) == NULL ) { fprintf(stderr, "fopen() failed\n"); exit(EXIT_FAILURE); } /* remaining code */ } does the second approach produce any additional cost, when fopen fails? would love to hear your thoughts!

  • Python: How to make a cross-module variable?

    - by Dan Homerick
    The __debug__ variable is handy in part because it affects every module. If I want to create another variable that works the same way, how would I do it? The variable (let's be original and call it 'foo') doesn't have to be truly global, in the sense that if I change foo in one module, it is updated in others. I'd be fine if I could set foo before importing other modules and then they would see the same value for it.

  • What's the best way to reference a .DLL - as a normal reference or as a web service?

    - by dotnetdev
    Hi, What is the best way to reference an existing .NET dll (Class library)? Is there any benefit to expose web services from the class library and reference these as opposed to referencing the actual .dll (Although one benefit of the web service approach is the granularity and thus surface area exposed is up to you at coding time)? I am thinking with loose coupling in mind, as a criteria. Thanks

  • When does ref($variable) return 'IO'?

    - by Zaid
    Here's the relevant excerpt from the documentation of the ref function: The value returned depends on the type of thing the reference is a reference to. Builtin types include: SCALAR ARRAY HASH CODE REF GLOB LVALUE FORMAT IO VSTRING Regexp Based on this, I imagined that calling ref on a filehandle would return 'IO'. Surprisingly, it doesn't: use strict; use warnings; open my $fileHandle, '<', 'aValidFile'; close $fileHandle; print ref $fileHandle; # prints 'GLOB', not 'IO' perlref tries to explain why: It isn't possible to create a true reference to an IO handle (filehandle or dirhandle) using the backslash operator. The most you can get is a reference to a typeglob, which is actually a complete symbol table entry [...] However, you can still use type globs and globrefs as though they were IO handles. In what circumstances would ref return 'IO' then?

  • Remove leading whitespaces using variable length lookbehind in RegExp

    - by Shizhidi
    Hello, I'm wondering if variable length lookbehind assertions are supported in JavaScript's RegExp engine? For example, I'm trying to match the string "variable length" in the string "[a lot of whitespaces and/or tabs]variable length lookbehind", and I have something like this but it does not go well in various RegExp testers: ^(?<=[ \t]+).+(?= lookbehind) If it's an illegal pattern, what would be a good workaround to it? Thanks!
