• SSRS run SQL/DataSet conditionally

  - by MikeTWebb

  Hello.... I have an SSRS report that contains several subreports. The user has the ability to select/deselect which subreports they want to produce using several Boolean parameters. If a subreport is deselected then it is not rendered by setting the Visibility property. However, the DataSet associated with the de-selected subreport still executes causing the execution time to take longer than expected. Is there any way to tell a dataset on a subreport or Tablix not to execute based on a Parameter selection? Thanks

• Why is MenuItem.AdapterContextMenuInfo null when my list view has a custom adapter?

  - by gregm

  My question: Before I go and use an OnLongClickListener, is there a better way to pass the "what was clicked to create this context menu" information when your list view has a custom adapter? Here are some details: Normally, my code can just do something like this: public boolean onContextItemSelected(MenuItem item) { AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo(); and then go on and be happy. However, ever since I introduced a custom adapter, item.getMenuInfo() is null. This is a big problem, because my code no longer knows which item was clicked. (My custom Adapter makes each list row a checkbox and a text view) I tried this but failed: Created my own special AdapterContextMenuInfo (called "HasAViewMenuInfo"), but when I pass it in this method, it ends up being null in the menu public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) { super.onCreateContextMenu(menu, v, new HasAViewMenuInfo(v));

• Regex for Date DD-MM-YYYY

  - by Josh M

  I have the following expression which will be used as date validation in the HTML5 "pattern" attribute. ?:0[1-9]|1[0-9]|2[0-9])|(?:(?!02)(?:0[1-9]|1[0-2])-(?:30))|(?:(?:0[13578]|1[02])-31))-(?:(?:0[1-9]|1[0-2])-(?:19|20)[0-9]{2} I want it to allow only valid dates, using "-" as a separator. This means up to 29th in February if it's a leap year, and 30/31 for other months respectively. Currently, it only allows years starting with 2 (2012) and months up to 12 (December). But it limits the day to 29 regardless of which month. Can anybody help me fix it?

• How can I test if an input field contains foreign characters?

  - by zeckdude

  I have an input field in a form. Upon pushing submit, I want to validate to make sure the user entered non-latin characters only, so any foreign language characters, like Chinese among many others. Or at the very least test to make sure it does not contain any latin characters. Could I use a regular expression for this? What would be the best approach for this? I am validating in both javaScript and in PHP. What solutions can I use to check for foreign characters in the input field in both programming languages?

• boost test case for function taking user input

  - by oadams

  I have a function that takes in user input via std::cin: std::getline(std::cin, in); and creates a corresponding data structure by matching it with a regular expression. The function then returns this data structure. I'm using boost.test and I want to create a unit test to check that the output data type is correct given some inputs. However I don't know how to go about it since the input isn't passed as an argument to the function. EDIT: Is there a simple way to create a boost test case that feeds the function a string via standard input?

• PHP editors for Ubuntu

  - by mepo

  What are the Light weight PHP editors available for ubuntu? And is there a ubuntu version of the Notepad++ editor. For those who haven't used Notepad++, do not confuse it with Notepad.exe. Notepad.exe is the lightweight Windows editor by Microsoft. Notepad++ is an Open Source programmer's text editor for Windows based on SciTE. It has syntax highlighting, code collapsing, language recognition, macro recording, regular expression search and replace across line breaks and in files on disk, copy filenames and paths to clipboard, and many other advance text editing tools. Only the more full-featured editors for Linux would be likely to be suitable replacements for Notepad++. Thanks

• Is it possible to use the values method for a HashMap if the values are ArrayLists?

  - by Denman

  I'm stuck trying to get something to work in an assignment. I have a HashMap<Integer, ArrayList<Object>> called sharedLocks and I want to check whether a certain value can be found in any ArrayList in the HashMap. The following code obviously wouldn't work because Object[] can't be cast to ArrayList[], but it is a demonstration of the general functionality that I want. ArrayList[] values = (ArrayList[]) sharedLocks.values().toArray(); boolean valueExists = false; for (int i = 0; i < values.length; i++) { if (values[i].contains(accessedObject)) { valueExists = true; } } Is there a way for me to check every ArrayList in the HashMap for a certain value? I'm not sure how to use the values method for HashMaps in this case. Any help would be much appreciated.

• Question in Flex (parser)

  - by shkk

  Hello... I want to ask you a question about Flex, the program for parsing code. Supposing I have an instruction like this one, in the rules part: "=" BEGIN(attribution); <attribution>{var_name} { fprintf(yyout, "="); ECHO; } <attribution>";" BEGIN(INITIAL); {var_name} is a regular expression that matches a variable's name, and all I want to do is to copy at the output all the attribution instructions, such as a = 3; or b = a; My rule though cannot write with fprintf the left member of the attribution, but only = 3; or =a; One solution for that might be that, after I make the match "=" and I am in the attribution state, to go 2 positions back as to get the left operand as well. How can I do that in Flex?

• which type is best for three radiobuttons?

  - by Manog

  Maybe you consider this question trivial but im just curious what is your opinion. I have three radiobuttons. "Show blue", "Show red" and "Show all". I did it with nullable boolean. There is collumn in database where blue is 0 and red is 1 so in metode i have to translate bool to int to compare those values (i do it in c#).Of course it works, but i wonder if it is the best solution. And question is wich type is best in this case? nullable bool, int, or maybe string?

• F# match char values

  - by rwallace

  I'm trying to match an integer expression against character literals, and the compiler complains about type mismatch. let rec read file includepath = let ch = ref 0 let token = ref 0 use stream = File.OpenText file let readch() = ch := stream.Read() let lex() = match !ch with | '!' -> readch() | _ -> token := !ch ch has to be an int because that's what stream.Read returns in order to use -1 as end of file marker. If I replace '!' with int '!' it still doesn't work. What's the best way to do this?

• Nesting arrays into NSDictionary object (Objective-C)

  - by antalbud

  I would like to define tasks using NSDictionary, which I'd like to save in a plist file (I didn't have much luck with Core Data so far), but got stuck at two points: -- When using initWithObjectsAndKeys: I can change the data type to number or boolean, using NSDate's numberWithInt: and numberWithBool: methods, respectively. I can't seem to find the method to change the type to date though. I couldn't find anything like that in the documentation. -- The second problem I ran into was with the nested arrays. How can I add them to the dictionary? I have uploaded a picture to here of what I am trying to achieve. Thank you in advance!

• [VB.NET] Same name methods in different modules cause ambiguity.

  - by smwikipedia

  I have 2 modules. Each contains a Sub with the same name. See below: Module moduleA Public Sub f(ByVal arg1 As myType) Console.WriteLine("module A") End Sub End Module Module moduleB Public Sub f(ByVal arg1 As myType, ByVal arg2 As Boolean) Console.WriteLine("module B") End Sub End Module But the compiler complains that there's ambiguity between moduleA and moduleB. How could this be? I have totally different signatures. However, if I put the 2 methods into the same module, there's no ambiguity at all. Could someone tell me why? Many thanks.

• Erlang bit syntax variable issue

  Is there any way to format this so it's a valid expression, without adding another step? <<One:8,_:(One*8)>> = <<1,9>>. * 1: illegal bit size These work <<One:8,_:(1*8)>> = <<1,9>>. <<1,9>> <<Eight:8,_:Eight>> = <<8,9>>. <<8,9>> I'm trying to parse a binary with nested data with list comprehensions instead of stacking accumulators.

• What does this method's return statement return?

  - by Kevin

  I saw a method written in C# that returns a boolean value. The method's return statement looks like this: return count > 0; If I'm reading this correctly, it returns a value if count is greater than zero. What happens if the value of 'count' is not greater than 0? What gets returned? Zero? If that's the case, couldn't the return statement just say: return count;

• Bash, Concatenating 2 strings to reference a 3rd variable

  I have a bash script I am having some issues with concatenating 2 variables to call a 3rd. Here is a simplification of the script, but the syntax is eluding me after reading the docs. server_list_all="server1 server2 server3"; var1 = "server"; var2 = "all"; echo $(($var1_list_$var2)); This is about as close as I get to the right answer, it acknowledges the string and tosses an error on tokenization. syntax error in expression (error token is "server1 server2 server3.... Not really seeing anything in the docs for this, but it should be doable. EDIT: Cleaned up a bit

• Some pro regular expressions help needed here

  - by Camran

  I need a special regular expression, have no experience in them whatsoever so I am turning to you guys on this one: I need to validate a classifieds title field so it doesn't have any special characters in it, almost. Only letters and numbers should be allowed, and also the swedish three letters å, ä, ö, and also not case sensitive. Besides the above, these should also be allowed: The "&" sign. Parenthesis sign "()" Mathematical signs "-", "+", "%", "/", "*" Dollar and Euro signs Accent sign or whatever it's called, for example in "coupé" the apostrophe above the "e". Double quote and singel quote signs. The comma "," and point "." signs Thanks

• Why is Hibernate not loading a column?

  - by B.R.

  I've got an entity with a few properties that gets used a lot in my Hibernate/GWT app. For the most part, everything works fine, but Hibernate refuses to load one of the properties. It doesn't appear in the query, despite being annotated correctly in the entity. The relevant portion of the entity: @Column(name="HasSubSlots") @Type(type="yes_no") public boolean hasSubSlotSupport() { return hasSubSlotSupport; } And the generated SQL query: Hibernate: /* load entities.DeviceModel */ select devicemode0_.DevModel as DevModel1_0_, devicemode0_.InvModelName as InvModel2_1_0_ from DeviceModels devicemode0_ where devicemode0_.DevModel=? Despite the fact that I refer to that property, it's never loaded, lazily or not, and the getter always returns false. Any ideas on how I can dig deeper into this, or what might be wrong?

• Regex: Match opening/closing chars with spaces

  - by Israfel

  I'm trying to complete a regular expression that will pull out matches based on their opening and closing characters, the closest I've gotten is ^(\[\[)[a-zA-Z.-_]+(\]\]) Which will match a string such as "[[word1]]" and bring me back all the matches if there is more than one, The problem is I want it to pick up matchs where there may be a space in so for example "[[word1 word2]]", now this will work if I add a space into my pattern above however this pops up a problem that it will only get one match for my entire string so for example if I have a string "Hi [[Title]] [[Name]] [[surname]], How are you" then the match will be "[[Title]] [[Name]] [[surname]]" rather than 3 matches "[[Title]]", "[[Name]]", "[[surname]]". I'm sure I'm just a char or two away in the Regex but I'm stuck, How can I make it return the 3 matches. Thanks

• Delayed evaluation in Clojure

  - by StackedCrooked

  I'm having some trouble understanding how the delay macro works in Clojure. It doesn't seem to do what expect it to do (that is: delaying evaluation). As you can see in this code sample: ; returns the current time (defn get-timestamp [] (.getTime (java.util.Date.))) ; var should contain the current timestamp after calling "force" (def current-time (delay (get-timestamp))) However, calling current-time in the REPL appears to immediately evaluate the expression, even without having used the force macro: user=> current-time #<Delay@19b5217: 1276376485859> user=> (force current-time) 1276376485859 Why was the evaluation of get-timestamp not delayed until the first force call?

• Creating Slugs from Titles?

  - by James Jeffery

  I have everything in place to create slugs from titles, but there is one issue. My RegEx replaces spaces with hyphens. But when a user types "Hi     there" (multiple spaces) the slug ends up as "Hi-----there". When really it should be "Hi-there". Should I create the regular expression so that it only replaces a space when there is a character either side? Or is there an easier way to do this?

• what is the accepted naming convention for int, string, array, list, object, etc...

  - by RJ

  The company I work for now uses a set naming convention for their C# variables such as iSomeName for int, sSomeName for string, aSomeName for arrays, bSomeName for boolean, dSomeName for datetime and so on. My previous employer did not use the i, s, a, b and d prefixes and just named the variables a good understandable name. My impression is that these prefixes lost favor a while ago and from what I read it is not the current trend. It seems fine to me either way as long as the variable is descriptive enough to understand what it is doing but I was wondering what the now-a-day accepted practice is for naming variables?
