• Do you have any recommendations on Blend/XAML books/tutorials for designers?

  - by Lenik

  There are a lot of WPF resources that are aiming developers. We are trying to get our designer up-to speed, and I have been researching some of the options on the market. The only two reasonable options that I found were "Expression Blend Unleashed" and "APress Foundation Expression Blend 2 Building Applications in WPF and SilverLight". Do people have any recommendations on blend/xaml books/tutorials for designers?

• COMException when trying to use a Library

  - by sarkie

  Hi Guys, I have an ASP.net WebService which uses a Library, this has a dependency on some third party .dlls. If I add a reference to the Library to my webservice, I get a COMException and I can't load the site. I thought it may be to do with aspnet user credentials, so I have tried impersonating and using processModel in machine.config but nothing seems to work. The .dlls are for communicating with hardware so I am not even using them on the server just other parts of the library, is there any way I can fix this? I'm running on Windows XP Pro SP3 with Visual 2008 SP1 and .net 3.5. I am thinking the only way of fixing it, is to split up the library into hardware and non-hardware based. Cheers, Sarkie The specified procedure could not be found. (Exception from HRESULT: 0x8007007F) Description: An unhandled exception occurred during the execution of the current web request.

• Multiple Conditions in Lambda Expressions at runtime C#

  - by Ryan

  Hi, I would like to know how to be able to make an Expression tree by inputting more than one parameter Example: dataContext.Users.Where(u => u.username == "Username" && u.password == "Password") At the moment the code that I did was the following but would like to make more general in regards whether the condition is OR or AND public Func<TLinqEntity, bool> ANDOnlyParams(string[] paramNames, object[] values) { List<ParameterExpression> paramList = new List<ParameterExpression>(); foreach (string param in paramNames) { paramList.Add(Expression.Parameter(typeof(TLinqEntity), param)); } List<LambdaExpression> lexList = new List<LambdaExpression>(); for (int i = 0; i < paramNames.Length; i++) { if (i == 0) { Expression bodyInner = Expression.Equal( Expression.Property( paramList[i], paramNames[i]), Expression.Constant(values[i])); lexList.Add(Expression.Lambda(bodyInner, paramList[i])); } else { Expression bodyOuter = Expression.And( Expression.Equal( Expression.Property( paramList[i], paramNames[i]), Expression.Constant(values[i])), Expression.Invoke(lexList[i - 1], paramList[i])); lexList.Add(Expression.Lambda(bodyOuter, paramList[i])); } } return ((Expression<Func<TLinqEntity, bool>>)lexList[lexList.Count - 1]).Compile(); } Thanks

• SQL: Return "true" if list of records exists?

  - by User

  An alternative title might be: Check for existence of multiple rows? Using a combination of SQL and C# I want a method to return true if all products in a list exist in a table. If it can be done in all in SQL that would be preferable. I have written a method that returns whether a single productID exists using the following SQL: SELECT productID FROM Products WHERE ProductID = @productID If this returns a row, then the c# method returns true, false otherwise. Now I'm wondering if I have a list of product IDs (not a huge list mind you, normally under 20). How can I write a query that will return a row if all the product id's exist and no row if one or more product id's does not exist? (Maybe something involving "IN" like: SELECT * FROM Products WHERE ProductID IN (1, 10, 100))

• Objective-C : BOOL vs bool

  - by santoni

  Hi, I'm new to objective-c and I saw the "new type" BOOL (YES, NO). I read that this type is almost like a char. For testing I did : NSLog(@"Size of BOOL %d", sizeof(BOOL)); NSLog(@"Size of bool %d", sizeof(bool)); Good to see both display 1 (sometimes in C++ bool just an int and sizeof is 4) So I was just wondering I there were some issues with the bool type or something ? Can I just use bool (that seems to work) without loosing speed? Thanks for answers

• Static analysis of multiple if statements (conditions)

  - by koppernickus

  I have code similar to: if conditionA(x, y, z) then doA() else if conditionB(x, y, z) then doB() ... else if conditionZ(x, y, z) then doZ() else throw ShouldNeverHappenException I would like to validate two things (using static analysis): If all conditions conditionA, conditionB, ..., conditionZ are mutually exclusive (i.e. it is not possible that two or more conditions are true in the same time). All possible cases are covered, i.e. "else throw" statement will never be called. Could you recommend me a tool and/or a way I could (easily) do this? I would appreciate more detailed informations than "use Prolog" or "use Mathematica"... ;-)

• XPath expression with condition on multiple ancestors

  - by Rest Wing

  The application I am developing receives an XML structure similar to following: <Root> <Valid> <Child name="Child1" /> <Container> <Child name="Child2" /> </Container> <Container> <Container> <Child name="Child3"/> <Child name="Child4"/> </Container> </Container> <Wrapper> <Child name="Child5" /> </Wrapper> <Wrapper> <Container> <Child name="Child19" /> </Container> </Wrapper> <Container> <Wrapper> <Child name="Child6" /> </Wrapper> </Container> <Container> <Wrapper> <Container> <Child name="Child20" /> </Container> </Wrapper> </Container> </Valid> <Invalid> <Child name="Child7" /> <Container> <Child name="Child8" /> </Container> <Container> <Container> <Child name="Child9"/> <Child name="Child10"/> </Container> </Container> <Wrapper> <Child name="Child11" /> </Wrapper> <Container> <Wrapper> <Child name="Child12" /> </Wrapper> </Container> </Invalid> </Root> I need to get a list of of Child elements under following conditions: Child is n generation descendant of Valid ancestor. Child may be m generation descendant of Container ancestor which is o generation descendant of Valid ancestor. Valid ancestors for Child element are Container elements as m generation ancestors and Valid element as first generation ancestor. where m, n, o are natural numbers. I need to write following XPath expressions Valid/Child Valid/Container/Child Valid/Container/Container/Child Valid/Container/Container/Container/Child ... as a single XPath expression. For provided example, the XPath expression would return only Child elements having name attribute equal to Child1, Child2, Child3 and Child4. The closest I have come to solution is following expression. Valid/Child | Valid//*[self::Container]/Child However, this would select Child element with name attribute equal to Child19 and Child20. Does XPath syntax supports either optional occurrence of an element or setting condition similar to self in previous example to all ancestors between Child and Valid elements?

• missing value true / false: error in loop not in one-off

  I am new on R and I have a problem with a test in a loop that I want to code. With a data frame (tabetest) like the one here after: Date 25179M103 1 14977 77.7309 2 14978 77.2567 3 14979 77.7507 I have: if(tabetest[3,"Date"]-tabetest[1,"Date"]1){print("ok")} [1] "ok" But: j=1 > position = 1 > price=tabetest for (i in 1:nrow(tabetest)-position){if(tabetest[i+position,"Date"]-tabetest[position,"Date"]>20){price[i+position,j]=price[i+position,j]/price[position,j]-1};position=position+1} Returns an error. R says that there is a missing value where true/false is required in: if (tabetest[i + position, "Date"] - tabetest[position, "Date"] > I have spent quite some time on that error but still don't understand where it comes from.

• Why overload true and false instead of defining bool operator?

  - by Joe Enos

  I've been reading about overloading true and false in C#, and I think I understand the basic difference between this and defining a bool operator. The example I see around is something like: public static bool operator true(Foo foo) { return (foo.PropA > 0); } public static bool operator false(Foo foo) { return (foo.PropA <= 0); } To me, this is the same as saying: public static implicit operator bool(Foo foo) { return (foo.PropA > 0); } The difference, as far as I can tell, is that by defining true and false separately, you can have an object that is both true and false, or neither true nor false: public static bool operator true(Foo foo) { return true; } public static bool operator false(Foo foo) { return true; } //or public static bool operator true(Foo foo) { return false; } public static bool operator false(Foo foo) { return false; } I'm sure there's a reason this is allowed, but I just can't think of what it is. To me, if you want an object to be able to be converted to true or false, a single bool operator makes the most sense. Can anyone give me a scenario where it makes sense to do it the other way? Thanks

• Why am I getting such random results when checking DNS?

  - by animuson

  The code is as follows: $domain = "fosajfjdkgdajfhsd.com"; $check1 = checkdnsrr($domain, "MX"); $check2 = checkdnsrr($domain, "A"); $check3 = (checkdnsrr($domain, "MX") || checkdnsrr($domain, "A")); $check4 = !(checkdnsrr($domain, "MX") || checkdnsrr($domain, "A")); die("{$check1} - {$check2} - {$check3} - {$check4}"); However when I check the output to see what it's returning, I get this: - 1 - 1 - The domain obviously wouldn't exist, so I don't understand why checking the A record is return true and checking the MX result doesn't give me anything at all. I don't understand what's going wrong here.

• Logical equality in C

  [It seems odd this doesn't exist, so apologies in advance if it's a duplicate] I want to test for logical equality in C. In other words, I want to know whether two values would be equal if both were converted in the normal way associated with logical expressions. In C99, I think that (bool)a == (bool)b gives what I want. Is that correct? What is the normal way of writing this in traditional C?

• How to access a list in OCaml

  - by Erik

  I want to write a function that could check every item in a list is true or false. If at least one element is false, it will return true, so that: assert_eq "checkFalse [true; false; true]" (checkFalse [true; true; true]) false; assert_eq "checkFalse [false; false]" (checkFalse [false; true]) true; I am an absolute beginner in OCaml and I don't know how to approach this. I tried using a for loop, something like: let rec checkFalse (bools: bool list) : bool = for i = 0 to bools.length do if bools.length == false then false else... (I don't know how to continue) Then it said "Unbound record field...." I also tried using find like: if (find false bools != Not_found) then true else false But my ways did not work. I came from a Java background. Thank you very much!
