• Need to create regular expression in Javascript to check the valid conditional string

  - by user1796078

  I want to create the regular expression in javascript which will check the valid conditional string like -1 OR (1 AND 2) AND 1 -1 OR (1 AND 2) -1 OR 2 -1 OR 1 OR 1 -1 AND 1 AND 1 The string should not contain 'AND' and 'OR'. For example - 1 OR 2 AND 3 is invalid. -It should be (1 OR 2) AND 3 or 1 or (2 AND 3). I tried the following Regex. It works for most of the conditions but it is failing to check the above condition. /^(\s*\(\d+\s(AND|OR)\s\d+\)|\s*\d+)((\s*(AND|OR)\s*)(\(\d+\s(AND|OR)\s\d+\)|\s*\d+))*$/ Can anyone please help me to sort out the above problem.

• Conditional jump or move depends on uninitialised value - freeing a linked list

  - by user720491

  I want to free a linked list in C. All is working fine, but Valgrind is telling me Conditional jump or move depends on uninitialised value(s) at 0x401400: mtf_destroy Here's the code: list_elt *head; void mtf_init() { list_elt *current; head = malloc(sizeof(list_elt)); current = head; for (int i = 0; i < LIST_SIZE-1; i++) { current->value = (BYTE) i; current->next = malloc(sizeof(list_elt)); current = current->next; } current->value = LIST_SIZE-1; } void mtf_destroy(list_elt *elt) { if (elt->next != NULL) mtf_destroy(elt->next); free(elt); } How can I solve this? Thanks!

• How can I use "IF statements" in a postgres trigger

  - by Dan B

  I have a trigger function that I only want to fire on certain instances of INSERTS, in this case, if do_backup = true. If it fires in all instances, I get an infinite loop. The logic seems pretty simple to me, and the rest of the function works. But the trigger function does not seem to register my conditional and always runs, even when backup = true. CREATE OR REPLACE FUNCTION table_styles_backup() RETURNS TRIGGER AS $table_styles_backup$ DECLARE ... do_backup boolean; BEGIN SELECT backup INTO do_backup FROM table_details WHERE id=NEW.table_meta_id; IF (do_backup = true) THEN ... INSERT INTO table_styles_versions ( ... ) VALUES ( ... ); END IF; RETURN NULL; END; $table_styles_backup$ LANGUAGE plpgsql; CREATE TRIGGER table_styles_backup AFTER INSERT ON table_styles FOR EACH ROW EXECUTE PROCEDURE table_styles_backup();

• Conditional includes in Classic ASP - where the file may not exist on the server

  - by Brent

  I am currently in a situation where I have to make some additions to an application written in classic ASP using server-side JScript on IIS. The additions that I need to make involve adding a series of includes to the server-side code to extend the application's capabilities. However, the inc files may not exist on the server in all cases, so I need the application to fall back to the existing behavior (ignore the includes) if the files do not exist, rather than generating an error. I know that this can't be accomplished using if statements in the JScript code because of the way that SSI works, and have not come across any ways of dynamically including the code on the server side, where the files may not exist. Does anyone know of a way to accomplish this in classic ASP? Any help would be much appreciated.

• Google App Engine (python): TemplateSyntaxError: 'for' statements with five words should end in 'rev

  - by Phil

  This is using the web app framework, not Django. The following template code is giving me an TemplateSyntaxError: 'for' statements with five words should end in 'reversed' error when I try to render a dictionary. I don't understand what's causing this error. Could somebody shed some light on it for me? {% for code, name in charts.items %} <option value="{{code}}">{{name}}</option> {% endfor %} I'm rendering it using the following: class GenerateChart(basewebview): def get(self): values = {"datepicker":True} values["charts"] = {"p3": "3D Pie Chart", "p": "Segmented Pied Chart"} self.render_page("generatechart.html", values) class basewebview(webapp.RequestHandler): ''' Base class for all webapp.RequestHandler type classes ''' def render_page(self, filename, template_values=dict()): filename = "%s/%s" % (_template_dir, filename) path = os.path.join(os.path.dirname(__file__), filename) self.response.out.write(template.render(path, template_values))

• Suppressing NSLog statements for release?

  - by fuzzygoat

  I wonder if someone could help me setup a number of NSLog statements so they print to console when executing in "Debug Mode" but don't print in "Release Mode". I understand I need to add something like DEBUG = 1 to the debug config in Xcode but I can't find where. Also how do I utilise this in my code? NSLog(@"Print Always"); if(DEBUG) NSLog(@"Print only in debug"); Is there a simple way of doing this? EDIT: I tried following this but when I entered either: OTHER_CFLAGS or GCC_PREPROCESSOR_DEFINITIONS Xcode informed me that "theres already another key named .... " gary

• Conditional Operator in SQL Where Clause

  - by Marc

  I'm wishing I could do something like the following in SQl Server 2005 (which I know isnt valid) for my where clause. Sometimes @teamID (passed into a stored procedure) will be the value of an existing teamID, otherwise it will always be zero and I want all rows from the Team table. I researched using Case and the operator needs to come before or after the entire statement which prevents me from having a different operator based on the value of @teamid. Any suggestions other than duplicating my select statements. declare @teamid int set @teamid = 0 Select Team.teamID From Team case @teamid when 0 then WHERE Team.teamID > 0 else WHERE Team.teamID = @teamid end

• Building path independent mod_rewrite statements for generic .htaccess file

  - by Pekka

  Say I have three small web applications stored under a shared web root: www.example.com/app1/ www.example.com/app2/ www.example.com/app3/ www.example.com/app4/ each application has a .htaccess file containing some run-off-the-mill mod_rewrite statements to rewrite urls like RewriteCond %{REQUEST_URI} ^/app1/([^/]+)/([^/]+)\.html$ RewriteRule .* /app1/index.php?selectedProfile=%1&match=%2&%{QUERY_STRING} now, I would like to have a generic .htaccess file in each /app{n} directory. So, no RewriteBase and no /app{n} prefix in the RewriteConds. One idea I had was making the first level a wildcard directory as well: RewriteCond %{REQUEST_URI} ^/([^/]+)/([^/]+)/([^/]+)\.html$ seeing as the .htaccess file gets triggered only when the /app{n} directory is entered, this should work. Is this an acceptable solution? Are there other, better ones?

• How to get debugging statements for Android in Eclipse

  - by Gerry

  I've read the lame documentation, and checked other answers. I'd like my Android app to print some debug statements in the logcat window of Eclispe. If I use the isLoggable method on the various types of debug levels on the Log class, I find that WARN and INFO are returning true. Log.w, and Log.i do not produce any output. Does anyone know which gotchas I've missed? And just to vent, why should this be hard? I've published apps for iphone and bberry and while appreciate the use of java, the platform is reeking of too many "genuiuses" being involved. I suppose Activities and Intents are very flexible, but why? I just want to put up some screens, take some input and show some results. The bberry pushscreen and popscreen is a lot less pretentious. Thanks, Gerry

• Using PHP variables inside SQL statements?

  - by Homer

  For some reason I can't pass a var inside a mysql statement. I have a function that can be used for multiple tables. So instead of repeating the code I want to change the table that is selected from like so, function show_all_records($table_name) { mysql_query("SELECT * FROM $table_name"); etc, etc... } And to call the function I use show_all_records("some_table") or show_all_records("some_other_table") depending on which table I want to select from at the moment. But it's not working, is this because variables can't be passed through mysql statements?

• Dealing with multiple Javascript IF statements.

  Is it possible to put multiple IF statements in Javascript? If so, I'm having a fair amount of trouble with the statement below.

I want to add another if data =='concept') between the two. if (data == 'valid') { $("#file").slideUp(function () { $("#file").before('<div class="approvedMessage">WIN WIN WIN!</div>'); setTimeout(ApprovedProof, 5000); }); function ApprovedProof() { $("#file").slideDown(); $('.approvedMessage').fadeOut(); } } else { $("#file").slideUp(function () { $("#file").before('<div class="deniedMessage">NO NO NO!</div>'); setTimeout(DeniedProof, 5000); }); function DeniedProof() { $("#file").slideDown(); $('.deniedMessage').fadeOut(); } }

• SQL Server 2008 - Script Data as Insert Statements from SSIS Package

  - by Brandon King

  SQL Server 2008 provides the ability to script data as Insert statements using the Generate Scripts option in Management Studio. Is it possible to access the same functionality from within a SSIS package? Here's what I'm trying to accomplish... I have a scheduled job that nightly scripts out all the schema and data for a SQL Server 2008 database and then uses the script to create a "mirror copy" SQLCE 3.5 database. I've been using Narayana Vyas Kondreddi's sp_generate_inserts stored procedure to accomplish this, but it has problems with some datatypes and greater-than-4K columns (holdovers from SQL Server 2000 days). The Script Data function looks like it could solve my problems, if only I could automate it. Any suggestions?

• How do I Put Several Select Statements into Different Columns

  - by Russ Bradberry

  I basically have 7 select statement that I need to have the results output into separate columns. Normally I would use a crosstab for this but I need a fast efficient way to go about this as there are over 7 billion rows in the table. I am using the vertica database system. Below is an example of my statements: SELECT COUNT(user_id) AS '1' FROM event_log_facts WHERE date_dim_id=20100101 SELECT COUNT(user_id) AS '2' FROM event_log_facts WHERE date_dim_id=20100102 SELECT COUNT(user_id) AS '3' FROM event_log_facts WHERE date_dim_id=20100103 SELECT COUNT(user_id) AS '4' FROM event_log_facts WHERE date_dim_id=20100104 SELECT COUNT(user_id) AS '5' FROM event_log_facts WHERE date_dim_id=20100105 SELECT COUNT(user_id) AS '6' FROM event_log_facts WHERE date_dim_id=20100106 SELECT COUNT(user_id) AS '7' FROM event_log_facts WHERE date_dim_id=20100107

• Write a function in c that includes the following sequence of statements [Wont Compile]

  - by Cody

  There is a question in my programming languages textbook that is as follows: Write a C function that includes the following sequence of statements: x = 21; int x; x = 42; Run the program and explain the results. Rewrite the same code in C++ and Java and compare the results. I have written code, and played with it in all three languages but I can not even get it to compile. This includes declaring x above the three lines as well as in the calling function (as this question is obviously attempting to illustrate scoping issues) I'd like to explain the results and do the comparisons on my own, as it is an assignment question but I was wondering if anyone had any insight as to how to get this code to compile? Thanks

• R: simple and short if clauses for combind statements

  - by jorgusch

  Hello, TRUE/FALSE if clauses are easily and quickly done in R. However, if the argument gets more complex, it also gets ugly very soon. For instance: I might want to execute different operations for a row(foo) dependent on the value in one cell (foo[1]). Let the intervals be 0:39 and 40:59 and 60:100 Something like does not exit: (if foo[1] "in" 40:60){... In fact, I only see ways of at least two if clauses and two else statements and the action for the first interval somewhere at the bottom of the code. With more intervals(or any other condition) it is getting more complex. Is there a best practice (for this purpose or others) with a simple construction and nice design to read? Thanks a lot!

• Conditional Batch file renaming with mysql data

  - by Paul Stevens

  Hello, I wonder if anyone knows how could I rename multiple files, all of them originally named with same structure, and add some data extracted from a mysql DB according to specifics rules. For example I have 500 files named with this vars: ID NAME ADDRESS PHONE.wav = 1234567 PAULSIMON WESTDR122 9942213456.wav Now I need to rename files taking some data from the databases for each file, and append the data from a query appended to the filename. For example add the data resulting from a query Where some conditions match, and the data to build the query is taked from original file name, as ID or NAME. i other words, lets say that I want to build a query taking ID & NAME from file 1234567 PAULSIMON WESTDR123 9942213456.wav as WHERE statements to take another value as BirthDATE and add this to new filename, so final result should be: ID NAME ADDRESS PHONE BIRTHDATE.wav I will appreciate any help on this. I need this to be done on a LINUX server.

• Excel 2007 Format Row of Cells containing certain text

  - by paradox

  I am attempting to perform conditional formatting in Excel 2007 by checking if a cell has a specific string in it and therefore highlighting the entire row corresponding to the text. However, Excel 2007's Conditional Formatting only allows me to highlight that specific cell. Is there a workaround to this without having to get my hands dirty with VBA?

• Pyjamas import statements

  - by Gordon Worley

  I'm starting to use Pyjamas and I'm running into some annoyances. I have to import a lot of stuff to make a script work well. For example, to make a button I need to first from pyjamas.ui.Button import Button and then I can use Button. Note that import pyjamas.ui.Button and then using Button.Button doesn't work (results in errors when you build to JavaScript, at least in 0.7pre1). Does anyone have a better example of a good way to do the import statements in Pyjamas than what the Pyjamas folks have on their site? Doing things their way is possible, but ugly and overly complicated from my perspective, especially when you want to use a dozen or more ui components.

• VBScript - using IF statements in a mail script?

  - by Kenny Bones

  I really need some quick tips here. I've got this VBScript script which sends an e-mail. And I want to do several checks to see if an attribute is true and if it is, write an additional line in the mail. How can I do this? This is part of the script: obMessage.HTMLBody = ""_ & "<MENU>"_ & "<LI type = square>This is a line</i>."_ I want something which looks like this: obMessage.HTMLBody = ""_ & "<MENU>"_ If statement1 = true Then & "<LI type = square>This is an additional line</i>."_ end if Preferrably, could some select statements be made? I don't really mind what the code looks like, I just want it to work as soon as possible :)

• Oracle 10g multiple DELETE statements

  - by bmw0128

  I'm building a dml file that first deletes records that may be in the table, then inserts records. Example: DELETE from foo where field1='bar'; DELETE from foo where fields1='bazz'; INSERT ALL INTO foo(field1, field2) values ('bar', 'x') INTO foo(field1, field2) values ('bazz', 'y') SELECT * from DUAL; When I run the insert statement by itself, it runs fine. When I run the deletes, only the last delete runs. Also, it seems to be necessary to end the multiple insert with the select, is that so? If so, why is that necessary? In the past, when using MySQL, I could just list multiple delete and insert statements, all individually ending with a semicolon, and it would run fine.
