• How to marshal a COM-Parameter as VT_ARRAY of VT_RECORD

  - by Oliver Japes

  I've already done some extensive search, but I can't seem to find anything matching my problem. The task I'm currently working on is to create a WCF-Wrapper for some DCOM-Objects. This already works great for the most parts, but now I'm stuck with one invocation that expects a VT_ARRAY containing VT_RECORD-Objects. Marshalling as VT_ARRAY is not a problem, but how can I tell COM that the elements in this array are VT_RECORDs? This is the invocation as I current use it. InitTestCase(testCaseName, parameterFileName, testCase, cellInfos.ToArray()); The parameter I'm talking about is the last one. It's defined as List<CellInfo>, CellInfo itself is already attributed with Guid("7D422961-331E-47E2-BC71-7839E9E77D39") and ComVisible(true). It's not a struct but a class. This is the condition failing on the native side: if (VT_RECORD == varCellConfig.vt)... Because of old software using these interfaces, changing the native side is not an option Any idea?

• jQuery ajax() function is ignoring dataType parameter in Firefox

  - by ccleve

  I'm trying to use jQuery.ajax() to fetch some html, but Firefox is giving me a "junk after document element" error message. As explained here and here the problem seems to be that Firefox is expecting XML from the server, and when it doesn't parse correctly it throws the error. Here's my ajax code: jQuery.ajax({ url: name, dataType: "html", success: function(result) { console.log(result); }, error: function (jqXHR, textStatus, errorThrown) { console.log(errorThrown); } }); The server returns the html with these response headers: Accept-Ranges bytes Content-Length 2957 Last-Modified Tue, 02 Jul 2013 16:16:59 GMT Note that there's no content-type header. I'm sure that adding one would solve the problem, but that's not an option. The real problem is that Firefox appears to be ignoring the dataType: parameter in the ajax call. I've also tried adding contentType: and accepts: parameters, but it doesn't help. What am I missing here? How do I force Firefox to process the response as plain text?

• RPX API Call auth_info is returning "missing parameter" error

  - by James Lawruk

  I cannot get the RPX auth_info API call to work. It keeps returning the error: "Missing parameter: apiKey" I am using the C# RPX Helper Class provided on their Wiki:RPX Helper Class Below is my code in my Page_Load method. The RPX service works by sending a POST to a Url that I specify. My code gets the token from the post data shown below. Then I call the AuthInfo API method. string token = Request.Params["token"]; string apiKey = "xxxxxxxxxxxxxxx"; //my API key Rpx rpx = new Rpx(apiKey, "http://rpxnow.com"); XmlElement xmlElement = rpx.AuthInfo(token); Everything looks good. The token is populated. Within their code, the "apiKey" value pair is added to the post data written to the Request stream. Has anyone had luck with this? Any ideas why this is not working? Thanks.

• How to validate parameter values against a data source in Crystal Reports 2008

  - by mjh41

  I have a report designed in Crystal 2008. The report has a parameter field called "Member ID" that I want to use to get a string input from the user running the report. However, I want to do some sort of validation to ensure that the ID they entered is valid (it exists in a database table that I already have set up). Is there any way to do this? I know you can set up dynamic parameters that would give the user a dropdown list of Member ID values to choose from based on the data stored in my database table. But I don't want to make the user sort through thousands of IDs in a dropdown. I just want them to manually enter an ID and then have the report check the entered value against a database table. Is this possible?

• Set query FROM table using report parameter in BIRT

  - by Adam

  Hi, I am using the BIRT report writer, and I have multiple tables with the same data structure. In my report design, I want to select the table my query uses as a report parameter (as part of a mysql query in the data set) -- but I can't figure it out. When I create the data set, it's great that I can use parameters in the form of SELECT * FROM WHERE ?, and set these to report parameters, but I get an error if I set the ? to the table, such as: SELECT * FROM ? WHERE 1 Is there another way I can do this? As it's java, I assume the syntax follows that of a PreparedStatement. In BIRT 2.5 there is a property binding option under the data set dialog... and I've tried setting my query as: "SELECT * FROM "+params["DataTable"].value+" WHERE 1", but that was also results in an error.

• Purpose of dereferencing a pointer as a parameter in C.

  - by Leif Andersen

  I recently came along this line of code: CustomData_em_free_block(&em->vdata, &eve->data); And I thought, isn't: a->b just syntactic sugar for: (*a).b With that in mind, this line could be re-written as: CustomData_em_free_block(&(*em).vdata, &(*eve).data); If that's the case, what is the point of passing in &(*a), as a parameter, and not just a? It seems like the pointer equivalent of -(-a) is being passed in in, is there any logic for this? Thank you.

• Parse Complex WSDL Parameter Information in C#

  - by jaws

  I am attempting to parse WSDL, along the lines of the example given here. The author notes, in the comments, that the example is not capable of drilling down into complex data types. And in fact, when I run the example, it does not appear to even handle simple data types. I have poked around in System.Web.Services.Description.ServiceDescription class, which is used in the example, but cannot find any actual parameter or return type information at run-time. I gather that I may need to do some manual parsing of an xsd file? Both google and stackoverflow appear to lack a complete example of how to drill down into complex types programmatically, so... how should I do this?

• pow doesn't accept the second parameter to be a variable on gcc

  - by Daziplqa

  pow doesn't accept the second parameter to be a variable on gcc The following code works fine on VC++10 // file test.cc #include "stdafx.h" #include <stdio.h> #include <math.h> int main(void) { double x = 10; int y = 20; printf("%f\n", pow(x, y)); return 0; } But the following code doesn't not work on gcc: // test.c #include <stdio.h> #include <math.h> int main(void) { double x = 10; int y = 20; printf("%f\n", pow(x, y)); // error here, says no such function, however when pass the second argument in `pow` for the code runs by gcc, It works fine! return 0; }

• Autocomplete and Dynamic Parameter Passing

  - by abcParsing

  The code below works fine using jQuery UI 1.8 and jQuery 1.4.2 $("#sid_entry_box").autocomplete( {source:"autocomplete_sid.php?database="+database_name, minLength:4, delay:1000, enable:true, cacheLength:1 }); The database name is passed as a get parameter of the php call. In this application, I have two databases selected by a radio button. Since jQuery loads and assigns this function when the document is loaded, the database name is whatever was checked at that momemnt. What I really need to pass to the php call is the following: database=$("input[name=rf_database_option]:checked").val(); Is ther ean easy to understand way to be able to pass a dynamic dom value?

• Tuples of unknown size/parameter types

  - by myahya

  I need to create a map, from integers to sets of tuples, the tuples in a single set have the same size. The problem is that the size of a tuple and its parameter types can be determined at runtime, not compile time. I am imagining something like: std::map<int, std::set<boost::tuple> > but not exctly sure how to exactly do this, bossibly using pointers. The purpose of this is to create temporary relations (tables), each with a unique identifier (key), maybe you have another approach.

• Resolving the metadata token of a generic type parameter

  - by 280Z28

  Is there any way the .NET 4.0 (or earlier) reflection API to resolve a generic type parameter? See the two lines after my ArgumentException comment for my current attempt. [TestMethod] public void TestGenericParameterTokenResolution() { Type genericParameter = typeof(List<>).GetGenericArguments()[0]; Assert.IsTrue(genericParameter.IsGenericParameter); int metadataToken = genericParameter.MetadataToken; // make sure the metadata token is a GenericParam Assert.AreEqual(metadataToken & 0xFF000000, 0x2A000000); Module module = typeof(List<>).Module; // the following both throw an ArgumentException. Type resolvedParameter = module.ResolveType(metadataToken); resolvedParameter = (Type)module.ResolveMember(metadataToken); Assert.AreSame(genericParameter, resolvedParameter); }

• .NET Lambda Pass Method Parameter

  - by RM

  Hi All, I hope i'm missing something obvious, but I'm having some troubles defining a method that takes a parameter of a method to fetch the method information for the passed method. I do NOT want actually execute the method. I want to be able to do: busObject.SetResolverMethod<ISomeInterface>(x=>x.GetNameById); Where GetNameById is a method defined on the interface ISomeInterface. In this case, an example of the method being passed in's signature would be: MyVarA GetNameById(int id){ .... } In the above example, the SetResolverMethod's body should be able to return / store the string "GetNameById". There is no standard signature the method being passed in will conform to (except that it will always return an object of some kind). Currently I'm setting the method as a string (i.e. "GetNameById"), but I want it to be compile time checked, hence this question.

• Parameter for BPEL process

  - by Hubidubi

  Hi I use OpenESB + BPEL. I would like to use some parameter to set system specific settings (path, string constants, etc.). I tried to use a properties file that a simple java class should read up and use with this method (http://wiki.open-esb.java.net/Wiki.jsp?page=BPELSEHowToCallJavaMethods). The problem is that I can't create properties file in BPEL project (not supported). So I created a file by hand. But this file is not included in the deployed app. Is there any working solution for including property file or is there any other method to set parameters on BPEL process? Thanks, Hubidubi

• Double pointer as Objective-C block parameter

  - by George WS

  Is it possible (and if so, safe) to create/use a block which takes a double pointer as an argument? For instance: - (void)methodWithBlock:(void (^)(NSError **error))block; Additional context, research, and questions: I'm using ARC. When I declare the method above and attempt to call it, XCode autocompletes my method invocation as follows: [self methodWithBlock:^(NSError *__autoreleasing *error) {}]; What does __autoreleasing mean here and why is it being added? I presume it has something to do with ARC. If this is possible and safe, can the pointer still be dereferenced in the block as it would be anywhere else? In general, what are the important differences between doing what I'm describing, and simply passing a double pointer as a method parameter (e.g. - (void)methodWithDoublePointer:(NSError **)error;)? What special considerations, if any, should be taken into account (again assuming this is possible at all)?

• switch between two cursors based on parameter passed into stored procedure

  - by db83

  Hi, I have two cursors in my procedure that only differ on the table name that they join to. The cursor that is used is determined by a parameter passed into the procedure if (param = 'A') then DECLARE CURSOR myCursor IS SELECT x,y,z FROM table1 a, table2 b BEGIN FOR aRecord in myCursor LOOP proc2(aRecord.x, aRecord.y, aRecord.z); END LOOP; COMMIT; END; elsif (param = 'B') then DECLARE CURSOR myCursor IS SELECT x,y,z FROM table1 a, table3 b -- different table BEGIN FOR aRecord in myCursor LOOP proc2(aRecord.x, aRecord.y, aRecord.z); END LOOP; COMMIT; END; end if I don't want to repeat the code for the sake of one different table. Any suggestions on how to improve this? Thanks in advance

Any idea why I can't use getdate() in this context? Thanks.

• Compilers behave differently with a null parameter of a generic method

  - by Eyal Schneider

  The following code compiles perfectly with Eclipse, but fails to compile with javac: public class HowBizarre { public static <P extends Number, T extends P> void doIt(P value) { } public static void main(String[] args) { doIt(null); } } I simplified the code, so T is not used at all now. Still, I don't see a reason for the error. For some reason javac decides that T stands for Object, and then complains that Object does not conform to the bounds of T (which is true): HowBizarre.java:6: incompatible types; inferred type argument(s) java.lang.Number,java.lang.Object do not conform to bounds of type variable (s) P,T found : <P,T>void required: void doIt(null); ^ Note that if I replace the null parameter with a non-null value, it compiles fine. Which of the compilers behaves correctly and why? Is this a bug of one of them?
