    - by Vineel Kumar Reddy
    Hi All I am working with win32 API and my language of choice is pure C and no C++. Assume I have a project A that is present in Solution S in visual studio I want to add another project B(which has some common utility functions) in to S Now I want to reference Project B in Project A... So that I can use those utility functions from Project B source code level. I dont want it be used against dll of Project B assume project B contains some math related functions and i want to call the functions from Project A or project B contains come data structures and i want to make use of them in Project A How to achieve this.... thanks in advance

  • Merging elements inside a xml.etree.ElementTree

    - by theAlse
    I have a huge test data like the one provided below (and yes I have no control over this data). Each line is actually 6 parts and I need to generate an XML based on this data. Nav;Basic;Dest;Smoke;No;Yes; Nav;Dest;Recent;Regg;No;Yes; Nav;Dest;Favourites;Regg;No;Yes; ... Nav;Dest using on board;By POI;Smoke;No;Yes; Nav;Dest using on board;Other;Regg;No;Yes; The first 3 elements on each line denotes "test suites"-XML element and the last 3 element should create a "test case"-XML element. I have successfully converted it into a XML using the following code: # testsuite (root) testsuite = ET.Element('testsuite') testsuite.set("name", "Tests") def _create_testcase_tag(elem): global testsuite level1, level2, level3, elem4, elem5, elem6 = elem # -- testsuite (level1) testsuite_level1 = ET.SubElement(testsuite, "testsuite") testsuite_level1.set("name", level1) # -- testsuite (level2) testsuite_level2 = ET.SubElement(testsuite_level1, "testsuite") testsuite_level2.set("name", level2) # -- testsuite (level3) testsuite_level2 = ET.SubElement(testsuite_level2, "testsuite") testsuite_level2.set("name", level3) # -- testcase testcase = ET.SubElement(testsuite_level2, "testcase") testcase.set("name", "TBD") summary = ET.SubElement(testcase, "summary") summary.text = "Test Type= %s, Automated= %s, Available=%s" %(elem4, elem5, elem6) with open(input_file) as in_file: for line_number, a_line in enumerate(in_file): try: parameters = a_line.split(';') if len(parameters) >= 6: level1 = parameters[0].strip() level2 = parameters[1].strip() level3 = parameters[2].strip() elem4 = parameters[3].strip() elem5 = parameters[4].strip() elem6 = parameters[5].strip() lines_as_list.append((level1, level2, level3, elem4, elem5, elem6)) except ValueError: pass lines_as_list.sort() for elem in lines_as_list: _create_testcase_tag(elem) output_xml = ET.ElementTree(testsuite) ET.ElementTree.write(output_xml, output_file, xml_declaration=True, encoding="UTF-8") The above code generates an XML like this: <testsuite name="Tests"> <testsuite name="Nav"> <testsuite name="Basic navigation"> <testsuite name="Set destination"> <testcase name="TBD"> <summary>Test Type= Smoke test Automated= No, Available=Yes</summary> </testcase> </testsuite> </testsuite> </testsuite> <testsuite name="Nav"> <testsuite name="Set destination"> <testsuite name="Recent"> <testcase name="TBD"> <summary> Test Type= Reggression test Automated= No, Available=Yes </summary> </testcase> </testsuite> </testsuite> </testsuite> </testsuite> ... This is all correct, but as you can see I have created a whole tree for each line and that is not what I need. I need to combine e.g. all testsuite with the same name into one testsuite and also perform that recursively. So the XML looks like this instead: <testsuite name="Tests"> <testsuite name="Nav"> <testsuite name="Basic navigation"> <testsuite name="Set destination"> <testcase name="TBD"> <summary>Test Type= Smoke test Automated= No, Available=Yes</summary> </testcase> </testsuite> <testsuite name="Recent"> <testcase name="TBD"> <summary> Test Type= Reggression test Automated= No, Available=Yes </summary> </testcase> </testsuite> </testsuite> </testsuite> </testsuite> I hope you can understand what I mean, but level1, level2 and level3 should be unique with testcases inside. How should I do this? Please do not suggest the use of any external libraries! I can not install new libraries in customer site. xml.etree.ElementTree is all I have. Thanks

  • ADO.NET Commands and SQL query plans

    - by ingredient_15939
    I've been reading up on query plans and how to minimise duplicate plans being created by SQL Server for the same basic query. For example, if I understand correctly, sending both these query strings will result in 2 different query plans: "SELECT FirstName FROM Members WHERE LastName = 'Lee'" "SELECT FirstName FROM Members WHERE LastName = 'MacGhilleseatheanaich'" Using a stored procedure avoids this, as the query plan is the same, and "LastName" is passed as a variable, eg: CREATE PROCEDURE sp_myStoredProcedure @LastName varchar(100) AS SELECT FirstName FROM Members WHERE LastName = @LastName Go Now, my question is whether the same applies to the Command object (eg. SQLClient.SQLCommand in ADO.NET). The reason I ask is that string parameters don't have a defined max length, as in the code above. Take the following code: MyCmd.CommandText = "SELECT FirstName FROM Members WHERE LastName = @LastName" MyCmd.Parameters.AddWithValue("@LastName", "Lee") Then later: MyCmd.Parameters.Clear() MyCmd.Parameters.AddWithValue("@LastName", "MacGhilleseatheanaich") Since @LastName hasn't been declared to SQL Server as having a defined maximum length, will SQL Server create a new query plan for every different value when I execute the command this way?

  • How to rewrite the URL

    - by Kalpana
    I have a small application built using Seam 2.2, Richfaces 3.3, JBoss 5.1. Most of the page navigation adds the request parameters to the target URL. I would like to hide parameters to be hidden to the customer who is using the application (e.g. I would expect the URL to be something like "http://localhost:8080/books/Book.seam". The parameters (userId, orderId and cmId) are currently mapped to the backend bean via Book.page.xml. How do I prevent the request parameters from showing up in the browser URL, as it also allows the customer to manipulate the URL. We did look at seam URL re-writing feature, it talked about manipulating say the primary key id in a REST format, not sure how to accomplish something more complex like the above use case in a elegant fashion.

  • Frustration with generics

    - by sbi
    I have a bunch of functions which are currently overloaded to operate on int and string: bool foo(int); bool foo(string); bool bar(int); bool bar(string); void baz(int p); void baz(string p); I then have a bunch of functions taking 1, 2, 3, or 4 arguments of either int or string, which call the aforementioned functions: void g(int p1) { if(foo(p1)) baz(p1); } void g(string p1) { if(foo(p1)) baz(p1); } void g(int p2, int p2) { if(foo(p1)) baz(p1); if(bar(p2)) baz(p2); } void g(int p2, string p2) { if(foo(p1)) baz(p1); if(bar(p2)) baz(p2); } void g(string p2, int p2) { if(foo(p1)) baz(p1); if(bar(p2)) baz(p2); } void g(string p2, string p2) { if(foo(p1)) baz(p1); if(bar(p2)) baz(p2); } // etc. (The implementation of the g() family is just a placeholder. actually they are more complicated.) More types than the current int or string might have to be introduced at any time. The same goes for functions with more arguments than 4. The current number of identical functions is barely manageable. Add one more variant in either dimension and the combinatoric explosion will be so huge, it might blow away the application. In C++, I'd templatize g() and be done. I understand that .NET generics are different. <sigh> But I have been fighting them for two hours trying to come up with a solution that doesn't involve too much copy&paste of code. To no avail. Surely, C#/.NET/generics/whatever won't require me to type out identical code for a family of functions taking five arguments of either of three types? So what am I missing here?

  • Does changing the order of class private data members breaks ABI

    - by Dmitry Yudakov
    I have a class with number of private data members (some of them static), accessed by virtual and non-virtual member functions. There's no inline functions and no friend classes. class A { int number; string str; static const int static_const_number; public: // got virtual and non-virtual functions, working with these memebers virtual void func1(); void func2(); // no inline functions or friends }; Does changing the order of private data members breaks ABI in this case? class A { string str; static const int static_const_number; int number; // <-- integer member moved here ... };

  • Conditional macro expansion

    - by Dave DeLong
    Heads up: This is a weird question. I've got some really useful macros that I like to use to simplify some logging. For example I can do Log(@"My message with arguments: %@, %@, %@", @"arg1", @"arg2", @"arg3"), and that will get expanded into a more complex method invocation that includes things like self, _cmd, __FILE__, __LINE__, etc, so that I can easily track where things are getting logged. This works great. Now I'd like to expand my macros to not only work with Objective-C methods, but general C functions. The problem is the self and _cmd portions that are in the macro expansion. These two parameters don't exist in C functions. Ideally, I'd like to be able to use this same set of macros within C functions, but I'm running into problems. When I use (for example) my Log() macro, I get compiler warnings about self and _cmd being undeclared (which makes total sense). My first thought was to do something like the following (in my macro): if (thisFunctionIsACFunction) { DoLogging(nil, nil, format, ##__VA_ARGS__); } else { DoLogging(self, _cmd, format, ##__VA_ARGS__); } This still produces compiler warnings, since the entire if() statement is substituted in place of the macro, resulting in errors with the self and _cmd keywords (even though they will never be executed during function execution). My next thought was to do something like this (in my macro): if (thisFunctionIsACFunction) { #define SELF nil #define CMD nil } else { #define SELF self #define CMD _cmd } DoLogging(SELF, CMD, format, ##__VA_ARGS__); That doesn't work, unfortunately. I get "error: '#' is not followed by a macro parameter" on my first #define. My other thought was to create a second set of macros, specifically for use in C functions. This reeks of a bad code smell, and I really don't want to do this. Is there some way I can use the same set of macros from within both Objective-C methods and C functions, and only reference self and _cmd if the macro is in an Objective-C method?

  • Managing multiple AJAX calls to PHP scripts

    - by relativelycoded
    I have a set of 5 HTML dropdowns that act as filters for narrowing results returned from a mySQL database. The three pertinent filters are for "Province", "Region", and "City" selection, respectively. I have three functions: findSchools(), which runs when any of the filters (marked with CSS class .filter) are changed, and fetches the results via AJAX from a PHP script. Once that is done, two other functions are called... changeRegionOptions(), which, upon changing the "Province" filter, and updates the available options using the same method as the first function, but posting to a different script. changeCityOptions(), which runs if the "Region" filter was changed, and updates options, again using the same method. The problem is that since I want these AJAX functions to run simultaneously, and they by nature run asynchronously, I've tried using $.when to control the execution of the functions, but it doesn't fix the problem. The functions run, but the Region and City filters return blank (no options); the FireBug report shows absolutely no output, even though the POST request went through. The posted parameter for filter_province gets sent normally, but the one for region gets cut off at the end -- it sends as filter_region=, with no value passed. So I'm presuming my logic is wrong somewhere. The code is below: // When any of the filters are changed, let's query the database... $("select.filter").change(function() { findSchools(); }); // First, we see if there are any results... function findSchools() { var sch_province = document.filterform.filter_province.value; var sch_region = document.filterform.filter_region.value; var sch_city = document.filterform.filter_city.value; var sch_cat = document.filterform.filter_category.value; var sch_type = document.filterform.filter_type.value; $.post("fetch_results.php", { filter_province : sch_province, filter_region : sch_region, filter_city : sch_city, filter_category : sch_cat, filter_type : sch_type }, function(data) { $("#results").html(""); $("#results").hide(); $("#results").html(data); $("#results").fadeIn(600); } ); // Once the results are fetched, we want to see if the filter they changed was the one for Province, and if so, update the Region and City options to match that selection... $("#filter_province").change(function() { $.when(findSchools()) .done(changeRegionOptions()); $.when(changeRegionOptions()) .done(changeCityOptions()); }); }; This is just one of the ways I've tried to solve it; I've tried using an IF statement, and tried calling the functions directly inside the general select.filter.change() function (after findSchools(); ), but they all return the same result. Any help with this would be great!

    Hi I had added the Stored procedure in my Entity framework and i also imported the functions in the edmx. Is it must to add all the three functions insert, update, and delete functions to a table. I had tried with insert alone and also with all, but why can't i get the name of the stored procedure in the connection string. Let me know what i done clearly. I had added the sp i had imported the functions in the model browser. i had also mapped the insert, update and delete function to the table with return type only for insert and update. Still i can't get the name of SP in the connection string. Please let me know how could i resolve this issue. Thanks in Advance, Kamal.

  • Calling function dynamically by using Reflection

    - by Alaa'
    Hi, I'm generating dll files contain code like the following example : // using System; using System.Collections; using System.Xml; using System.IO; using System.Windows.Forms; namespace CSharpScripter { public class TestClass : CSharpScripter.Command { private int i=1; private int j=2; public int k=3; public TestClass6() { } public void display (int i,int j,int k) { string a = null; a= k.ToString(); string a1 = null; a1= this.i.ToString(); string a2 = null; a2= j.ToString(); MessageBox.Show(" working! "+ "k="+ a +" i="+a1 + " j="+ a2); } public void setValues(int i,int j,int k1) { this.i=i; this.j=j; k=k1; } // I'm compiling the pervious code, then I execute an object from the dll file. So, in the second part of the code ( Executing part), I'm just calling the execute function, It contains a call for a function, I named here: display. For that I need to set values in the declaration by a setValue function. I want it to been called dynamically (setValues ), which has declaration like : public void(Parameter[] parameters) { //some code block here } For this situation I used Reflection. // Type objectType = testClass.GetType(); MethodInfo members = objectType.GetMethod("setValues"); ParameterInfo[] parameters = members.GetParameters(); For) int t = 0; t < parameters.Length; t++) { If (parameters[t]. ParameterType == typeof()) { object value = this.textBox2.Text; parameters.SetValue)Convert.ChangeType(value,parameters[t].ParameterType), t); } } // But it throws an casting error" Object cannot be stored in an array of this type." at last line, in first parameter for (setValue) methode. What is the problem here? And How I can call the method Dynamically after the previous code, by( Invoke) or is there a better way? Thanks.

  • Ajax function partially fails when alert removed

I have a problem in the following code: //quesry the db for image information function queryDB (parameters) { var parameters = "p="+parameters; alert ("hello"); if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { // use the info alert (xmlhttp.responseText); } } xmlhttp.open("POST", "js/imagelist.php", true); //Send the proper header information along with the request xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); xmlhttp.setRequestHeader("Content-length", parameters.length); xmlhttp.setRequestHeader("Connection", "close"); xmlhttp.send(parameters); } When I remove the alert statement 4 lines down I hit problems. This function is being called by a loop, and without the alert, I only get results for the last value sent to the statement. With it, I get everything I was expecting and really I'm at a loss to know why. I've heard that this may be a timing issue as I'm sending new requests before the old one is finished. I also heard polling being mentioned, but I can't find any information detailed enough. I'm new to synchronous services and I'm not really aware of the issues.

  • AS3: Adding get/set methods to a class via prototype

    - by LiraNuna
    I'm looking for a way to extend a class via prototype by adding a get and set functions. The following code will add a function to the class' prototype: MyClass.prototype.newMethod = function(... args) { }; However I want to add both a get and set functions. I tried: MyClass.prototype.fakeProperty = get function(... args) { }; MyClass.prototype.fakeProperty = set function(... args) { }; But that seem to throw compile errors. Is this even possible? Is there some 'internal' naming convention for get/set functions? I am not looking for answers such as 'create a new class and new get/set functions there'.

  • Fastest method for SQL Server inserts, updates, selects from C# ASP.Net 2.0+

    - by Ian
    Hi All, long time listener, first time caller. I use SPs and this isn't an SP vs code-behind "Build your SQL command" question. I'm looking for a high-throughput method for a backend app that handles many small transactions. I use SQLDataReader for most of the returns since forward only works in most cases for me. I've seen it done many ways, and used most of them myself. Methods that define and accept the stored procedure parameters as parameters themselves and build using cmd.Parameters.Add (with or without specifying the DB value type and/or length) Assembling your SP params and their values into an array or hashtable, then passing to a more abstract method that parses the collection and then runs cmd.Parameters.Add Classes that represent tables, initializing the class upon need, setting the public properties that represent the table fields, and calling methods like Save, Load, etc I'm sure there are others I've seen but can't think of at the moment as well. I'm open to all suggestions.

  • Unit testing - how do I test a function that returns random output?

    - by Extrakun
    I have a function which takes in two parameters, and returns one or the other 50% of the time. The unit test for this should determine that both parameters could be returned. Luckily, I don't need to prove that the probability for each is 50% but I do need to show that both parameters are possible to be returned. How do I write a test case for this function?

  • Endianness manipulation - is there a C library for this?

    - by Malvineous
    Hi all, With the sort of programs I write (working with raw file data) I often need functions to convert between big and little endian. Usually I write these myself (which is covered by many other posts here) but I'm not that keen on doing this for a number of reasons - the main one being lack of testing. I don't really want to spend ages testing my code in a big endian emulator, and often just omit the code for big endian machines altogether. I also would rather make use of faster functions provided by various compilers, while still keeping my programs cross-platform. The only things I can find are socket calls like htons() but they require different #include files on each platform, and some GPL code like this, however that particular file, while comprehensive, seems to miss out on some of the high performance functions provided by some compilers. So, does anyone know of a library (ideally just a .h file) that is well tested and provides a standard set of functions for dealing with endianness across many compilers and platforms?
