reporting services - How to make objects inside a rectangle NOT move in SSRS? -

-
Image
i have rectangle , background image screenshot of form. i have placed many gauge panels on rectangle check marks need be. based on logic, gauge panel visible or not. the problem if gauge panels on left side hidden, moves gauge panels on right side. here's screenshot during design mode: and here's when run it: i'm assuming has moved because there no visible "yes" check mark. how should go making sure these panels fixed inside rectangle? edit - i tried putting items inside rectangles , i'm running same problem: place gauges inside fixed rectangles when they're not visible, container rectangles still take space in report on left side , not interfere checks on right hand side. my general rule of thumb when trying fixed layouts in ssrs use lot of rectangles, rendered absolute divs , therefore bend whim bit more in terms of heights, widths, , positioning.

regex - Regular expression to match a line that doesn't contain a word? -

-
i know it's possible match word , reverse matches using other tools (e.g. grep -v ). however, i'd know if it's possible match lines don't contain specific word (e.g. hede) using regular expression. input: hoho hihi haha hede code: grep "<regex 'doesn't contain hede'>" input desired output: hoho hihi haha the notion regex doesn't support inverse matching not entirely true. can mimic behavior using negative look-arounds: ^((?!hede).)*$ the regex above match string, or line without line break, not containing (sub)string 'hede'. mentioned, not regex "good" @ (or should do), still, is possible. and if need match line break chars well, use dot-all modifier (the trailing s in following pattern): /^((?!hede).)*$/s or use inline: /(?s)^((?!hede).)*$/ (where /.../ regex delimiters, i.e., not part of pattern) if dot-all modifier not available, can mimic same behavior character class [\...

i have tcp server setup receives strings of text clients. data = new byte[1024]; recv = client.receive(data); string recvconv = encoding.ascii.getstring(data, 0, recv); i can detect string , example: if (recvconv == "l") { console.writeline(encoding.ascii.getstring(data, 0, recv)); console.writeline("l printed..."); } however need detect part of string. example, "name:programmer". need able detect "name:" part, , assign "programmer" part of string variable. i not sure how this. have tried using substring, , other string techniques have no idea doing. you can use string.split method. https://msdn.microsoft.com/en-us/library/system.string.split%28v=vs.110%29.aspx data = new byte[1024]; recv = client.receive(data); string recvconv = encoding.ascii.getstring(data, 0, recv); string[] results = recvconv.split(':'); foreach (string result in results) { console.writeline(result); }

-
i have following json structure: { "communication": { "office": { "email": "test@example.com" }, "private": { "email": "test2@example.com" }, } } i want query dynamically email based on type e.g. office or private. when use following command: @query(value = "{ 'communication.?0.email' : ?1 }") object findbyemail(string type, string email); the 'communication.?0.email' is converted to 'communication."office".email' and mongo didn't find entry. how can avoid quotes before , after office? simple answer spring mongo doesn't supports looking for. why not passing parameter rather below. @query(value = "{ 'communication.?0.email' : ?1 }") object findbyemail(string type, string email); where email value should type= "communication." + type + ".email"

ocaml - Warning 8: Incomplete pattern matching warning in a let statement -

-
i pattern matching in let statement, know shape of result. clear cannot expect compiler infer knowledge, perhaps there's more idiomatic way in concise way. as example, please @ following code: type foo = of int | b of string let x = (true, 0) let (b, i) = x in + 2 which correctly warns me, result of (_, b _) not matched. possible way explicitly handle missing case in: let (b,i) = match x | (a, j) -> (a,j+2) | _ -> failwith "implementation error!" but obscures actual computation. there more concise alternative? edit: jeffrey scofield remarked in case without nesting, explicit conversion function work out well. there version nested type matching? if sure right case , using ocaml 4.02 or higher, can add [@@warning "-8"] declaration. see the ocaml manual more details on attributes. on previous versions of ocaml, can disable warning respect whole file (this depends on building workflow) or use explicit pattern matchi...

Generic Sequences -

i have following snippet. second variable declaration not compile though: type coin = ref object pen = ref object let yes : seq[ref object] = @[coin(), coin(), coin()] #compiles no : seq[ref object] = @[coin(), pen(), coin()] #does not compile is possible in nim have generic seqs, java's list ? nim sequences are generic, not putting same kind of objects in them. in java non-primitive types (including arrays) inherit either directly or indirectly object superclass , therefore having list<object> type can put in it. in nim not has have same root, , in case, while objects same, treated different types. need create class hierarchy java: type baseref = ref object of tobject coinref = ref object of baseref penref = ref object of baseref let test1: seq[baseref] = @[(baseref)coinref(), coinref(), coinref()] test2: seq[baseref] = @[(baseref)coinref(), penref(), coinref()] note @[] list constructor still needs prodding in correct dire...

ios - NSMutableDictionary treats NSString value as NSNumber -

-
Image
i have following value in nsmutabledictionary - see image i'm attempting @ "a" thus: let = dictionary.objectforkey("a") as! string the app crashes @ point with could not cast value of type '__nscfnumber' (0x...) 'nsstring' (0x...). other numbers inside "" treated strings numbers outside of strings cast string without issue. can let me know what's going on? , how @ these values easily? the value nsnumber , not nsstring . can use stringvalue convert it: if let = d["a"] as? nsnumber { let astring = a.stringvalue println(astring) // -1 } else { // either d doesn't have value key "a", or d value not nsnumber } if you're sure exists , nsnumber , can use forced unwrapping, forced casting, , string interpolation: let = d["a"]! as! nsnumber let astring = "\(a)"

list allows duplicates write logic dis-allow duplicates in list import java.util.*; class altest { public static void main(string[] args) { arraylist al=new arraylist(); al.add("a"); al.add("b"); al.add("a"); al.add(10); al.add(20); al.add("list"); system.out.println(al); } } here duplicated should not duplicate the easiest way use linkdhashset instead. prevent duplicates, , can still iterate on elements in same order added set.
