  • Sending url params and POST body to a MVC 2 Controller

    - by Luiggi
    Hi, I'm having some issues trying to make a HTTP PUT (or POST) using WebClient against a MVC 2 controller. The exception is: The parameters dictionary contains a null entry for parameter 'total' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult Company(System.Guid, Int32, Int32, System.String)' The controller action is: [HttpPut] public ActionResult Company(Guid uid, int id, int total, string url) The route is: routes.MapRoute( "CompanySet", "job/active/{uid}/company/{id}", new { controller = "Job", action = "Company" } ); As you may see, what I want is to send the 'uid' and 'id' parameters via url, but the 'total' and 'url' parameters as part of the PUT or POST body. I've also tried to merge the latter parameters into a class (i.e., CompanySetMessage), doing it no longer raises an exception but I dont receive the values on the server side. Any ideas? Thank you!

  • PHP Captcha without session

    - by Anton N
    Ok, here is an issue: in the project i'm working on, we can't rely on server-side sessions for any functionality. The problem is that common captcha solutions from preventing robotic submits require session to store the string to match captcha against. The question is - is there any way to solve the problem without using sessions? What comes to my mind - is serving hidden form field, containing some hash, along with captcha input field, so that server then can match these two values together. But how can we make this method secure, so that it couldn't be used to break captcha easily.

  • How to use multiple database in a PHP web application?

    - by Harish
    I am making a PHP web Application in which i am using MySQL as database server, i want to make backup of some tables from one database to another database(with that tables in it). i have created two different connection, but the table is not updated. $dbcon1 = mysql_connect(DB_SERVER,DB_USER,DB_PASSWORD) or die(mysql_error()); $dbase1 = mysql_select_db(TEMP_DB_NAME,$dbcon)or die(mysql_error()); $query1=mysql_query("SELECT * FROM emp"); while($row = mysql_fetch_array($query1, MYSQL_NUM)) { $dbcon2 = mysql_connect(DB_SERVER,DB_USER,DB_PASSWORD) or die(mysql_error()); $dbase2 = mysql_select_db(TEMP_DB_NAME2,$dbcon)or die(mysql_error()); mysql_query("INSERT INTO backup_emp VALUES(null,'$row[1]',$row[2])"); mysql_close($dbcon2); } the code above is taking the data of emp from first database, and updataing it into another backup_emp table of another database. the code is not working properly, is there any other way of doing this...please help.

  • Spring @Value annotation not using defaults when property is not present

    - by garyj
    Hi All I am trying to use @Value annotation in the parameters of a constructor as follows: @Autowired public StringEncryptor( @Value("${encryptor.password:\"\"}") String password, @Value("${encryptor.algorithm:\"PBEWithMD5AndTripleDES\"}") String algorithm, @Value("${encryptor.poolSize:10}") Integer poolSize, @Value("${encryptor.salt:\"\"}") String salt) { ... } When the properties file is present on the classpath, the properties are loaded perfectly and the test executes fine. However when I remove the properties file from the classpath, I would have expected that the default values would have been used, for example poolSize would be set to 10 or algorithm to PBEWithMD5AndTripleDES however this is not the case. Running the code through a debugger (which would only work after changing @Value("${encryptor.poolSize:10}") Integer poolSize to @Value("${encryptor.poolSize:10}") String poolSize as it was causing NumberFormatExceptions) I find that the defaults are not being set and the parameters are in the form of: poolSize = ${encryptor.poolSize:10} or algorithm = ${encryptor.algorithm:"PBEWithMD5AndTripleDES"} rather than the expected poolSize = 10 or algorithm = "PBEWithMD5AndTripleDES" Based on SPR-4785 the notation such as ${my.property:myDefaultValue} should work. Yet it's not happening for me! Thank you

  • convert string to dict using list comprehension in python

    - by Pavel
    I have came across this problem a few times and can't seem to figure out a simple solution. Say I have a string string = "a=0 b=1 c=3" I want to convert that into a dictionary with a, b and c being the key and 0, 1, and 3 being their respective values (converted to int). Obviously I can do this: list = string.split() dic = {} for entry in list: key, val = entry.split('=') dic[key] = int(val) But I don't really like that for loop, It seems so simple that you should be able to convert it to some sort of list comprehension expression. And that works for slightly simpler cases where the val can be a string. dic = dict([entry.split('=') for entry in list]) However, I need to convert val to an int on the fly and doing something like this is syntactically incorrect. dic = dict([[entry[0], int(entry[1])] for entry.split('=') in list]) So my question is: is there a way to eliminate the for loop using list comprehension? If not, is there some built in python method that will do that for me?

  • Iterating over two arrays at a time in Javascript

    - by Ankur
    I want to iterate over two arrays at the same time, as the values for any given index i in array A corresponds to the value in array B. I am currently using this code, and getting 'undefined' when I call queryPredicates[i] or queryObjects[i], I know my array is populated as I print out the array prior to calling this, I haven't put all the other code in as it might be confusing, but if you think the problem is not evident from this I will edit the question: function getObjectCount(){ variables = queryPredicates.length; //the number of variables is found by the length of the arrays - they should both be of the same length queryString="count="+variables; for(var i=1; i<=variables;i++){ alert(queryPredicates[i]); alert(queryObjects[i]); } Thanks

  • Right floated div within a liquid-width div. How do I get this to work?

    - by DavidR
    I have a div, within the div is a name in an <h4> tag (it's semantically correct with the layout) and a div with some values describing that <h4> value. I want the nested div to be on the right side, and the only way I can get this to work is a fixed-width container and float: right;. As you can guess, the object breaks when the value of the <h4> causes the nested div to overflow. I've tried min-width, but it ends up stretching to the maximum size of the div containing the container div.

  • two HashMap iteration

    - by user431276
    I have two HashMaps and I can iterate both hashmaps with following code Iterator it = mp.entrySet().iterator(); while (it.hasNext()) { Map.Entry pairs = (Map.Entry)it.next(); String firstVal = pairs.getValue(); } Iterator it2 = mp2.entrySet().iterator(); while (it2.hasNext()) { Map.Entry pairs2 = (Map.Entry)it.next(); String SecondVal = pairs2.getValue(); } myFunction(firstVal, SecondVal) Is there anyway to iterate two hashmaps at the same time without using two loops? Currently, I have a method that accepts two parameters and each parameter value is stored in first and second hashmap. I have to iterate first hash then second to get values. I think there must be a good way to do it but I don't know :( P.S: there could be some errors in above code as this is just an example to explain my problem. Each iterator is a method in original program and accept one parameter. I couldn't copy past real time functions as they are HUGE !

  • mysql LAST_INSERT_ID() used with multiple records INSERT statement

    - by bogdan
    Hello, If i insert multiple records with a loop that executes a single record insert, the last insert id returned is, as expected, the last one... but if i do a multiple records insert statement: INSERT INTO people (name,age) VALUES('William',25),('Bart',15),('Mary',12); let's say the three above are the first records inserted in the table...after the insert statement i expected last insert id to return 3, but it returned 1...the first insert id for the statement in question... So can someone please confirm if this is the normal behavior of LAST_INSERT_ID() in the context of multiple records INSERT statements...so i can base my code on it thanks :)

  • Circular dock/menu in css or jquery

    - by sasidhar
    Is it possible to have a circular menu or dock using css or jquery.? I have a set of images as the dock items that need to be displayed as a circular dock... however the number of items in the dock are not constant and may vary.... so i cannot tend to use constant values for positioning each item in a pre-defined manner. Ajax loads some images into this particular div and i need to use css or jquery to style this so that they get displayed as circular dock items. Any idea on how this can be implemented..? I would like a browser in-specific implementation, but i also welcome if some one has some solutions specific to few browsers... UPDATE I don't think i exactly want a pie menu... it easily gets messed up as the number of dock items increase. I am looking for a spiral dock. and by spiral i mean that the menu items must be in the following alignment..

    Hi ! I made a user interface in VBA with many textbox. I read an excel sheet and I put all the value of this one in all the textbox of my user inteface. So the user can modify the values and then save it in the excel sheet.

I tried to use tag or tabindex property but I don't find the good way to proceed .... Is someone know an easy way to solve this !!! Thanks

  • C# Design a class with interface?

    - by Haroon
    I am having a bit of trouble understanding how I will design a class. My class will have 3 methods ICollection<Field> GetFields(); //perform validation internally - return back the object T UpdateFields(ICollection<Field> fields); //pass in model object with values on it, set up fields, then pass back all fields ICollection<Field> GetFieldsWithValues(T object); What is the best way to construct/design such a class keeping in mind: 1. The model object I pass in will be one of 3 or 4 tables, however when I call GetFIelds - internally for each object I know what fields will be there i.e. list.add(new Field{name = "id", value = "5"}); list.add(new Field{name = "nameofcompany", value = "super guys"});

  • HD Crash SQL server -> DBCC - consistency errors in table 'sysindexes'

    - by Julian de Wit
    Hello A client of mine has had an HD crash an a SQL DB got corrupt : They did not make backups so they have a big problem. When I tried (an ultimate measure) to DBCC-repair I got the following message. Can anybody help me with this ? Server: Msg 8966, Level 16, State 1, Line 1 Could not read and latch page (1:872) with latch type SH. sysindexes failed. Server: Msg 8944, Level 16, State 1, Line 1 Table error: Object ID 2, index ID 0, page (1:872), row 11. Test (columnOffsets->IsComplex (varColumnNumber) && (ColumnId == COLID_HYDRA_TEXTPTR || ColumnId == COLID_INROW_ROOT || ColumnId == COLID_BACKPTR)) failed. Values are 2 and 5. The repair level on the DBCC statement caused this repair to be bypassed. CHECKTABLE found 0 allocation errors and 1 consistency errors in table 'sysindexes' (object ID 2). DBCC execution completed. If DBCC printed error messages, contact your system administrator.

  • Why does Python's __import__ require fromlist?

    - by ieure
    In Python, if you want to programmatically import a module, you can do: module = __import__('module_name') If you want to import a submodule, you would think it would be a simple matter of: module = __import__('module_name.submodule') Of course, this doesn't work; you just get module_name again. You have to do: module = __import__('module_name.submodule', fromlist=['blah']) Why? The actual value of fromlist don't seem to matter at all, as long as it's non-empty. What is the point of requiring an argument, then ignoring its values? Most stuff in Python seems to be done for good reason, but for the life of me, I can't come up with any reasonable explanation for this behavior to exist.

  • Scala loop returns as Unit and compiler points to "for" syntax?

    - by DeLongey
    Seems like Unit is the theme of my troubles today. I'm porting a JSON deserializer that uses Gson and when it comes to this for loop: def deserialize(json:JsonElement, typeOfT:Type, context:JsonDeserializationContext) = { var eventData = new EventData(null, null) var jsonObject = json.getAsJsonObject for(entry <- jsonObject.entrySet()) { var key = entry.getKey() var element = entry.getValue() element if("previous_attributes".equals(key)) { var previousAttributes = new scala.collection.mutable.HashMap[String, Object]() populateMapFromJSONObject(previousAttributes, element.getAsJsonObject()) eventData.setPreviousAttributes(previousAttributes) eventData } else if ("object".equals(key)) { val `type` = element.getAsJsonObject().get("object").getAsString() var cl = objectMap.get(`type`).asInstanceOf[StripeObject] var `object` = abstractObject.retrieve(cl, key) eventData.setObject(`object`) eventData } } } The compiler spits out the error type mismatch; found : Unit required: com.stripe.EventData and it points to this line here: for(entry <- jsonObject.entrySet()) Questions Confirm that it is indeed the Gson method entrySet() appearing as unit? If not, what part of the code is creating the issue? I've set return types/values for eventData class methods Is there a workaround for the Gson Unit issue? Thanks!

  • How do I force my std::map to deallocate memory used?

    - by monkeyking
    I'm using a std::map, and I can't seem to free the memory back to the OS. It looks like, int main(){ aMap m; while(keepGoing){ while(fillUpMap){ //populate m } doWhatIwantWithMap(m); m.clear(); //flush some buffered values into map for next iteration flushIntoMap(m); } } Each (fillUpmap) allocates around 1gig, so I'm very much interested in getting this back to my system before it eats up all my memory. Ive experienced the same with std::vector, but there I could force it to free by doing a swap with an empty std::vector. This doesn't work with map. When I use valgrind it says that all memory is freed, so its not a problem with a leak, since everything is cleared up nicely after a run.

  • I'm having a problem identifying a floating point exception.

    - by Peter Stewart
    I'm using c++ in visual studio express to generate random expression trees for use in a genetic algorithm type of program. Because they are random, the trees often generate (I'll call them exceptions, I'm not sure what they are) Thanks to a suggestion by George, I turned the mask _MCW_EM on so that hardware interrupts are turned off. (the default) So, the program runs uninterrupted, but some of the values returned are: -1.#INF, -1.#NAN, -1.#INV. I don't know how to identify these so that I can throw an exeption: if ( variable == -1.#INF) ?? DigitalRoss in this post seemed to have the solution, but as I understood it I couldn't make it work. I've been looking all over the place for this simple bit of code, that I assumed would be used all the time, but have had no luck. thanks

  • Querying a perimeter around a Geocode-Location (Lat/Lon)

    - by Tim
    Hi, how can I search for geo-objects in a certain perimeter ? E.g. I have several objects with Lat/Lon coordinates stored in my DB. Now I want to retrieve all the objects which lie in a specific perimeter (10 miles or 20 miles) around a given point. I guess what I would have to do is to form some query like: SELECT * FROM objects o where o.lat < (myPositionLat+x) AND o.lon < (myPositionLon+y) Is this right? How do I determine/set the values for x and y?

  • Is it OK to mixed NumberLong and normal integers in the same field in MongoDB?

    - by Nicholas Tolley Cottrell
    I have been using Morphia to persistent objects from Java. I have also been running some batch processes from the console. I just realised that some values are now stored as NumberLong and number as plain Javascript numbers. I have an index on this field. Everything seems to be ok, but if I query: {f: 100} from the console it still returns the object even if it actually contains {f: NumberLong(100)} Is this true of all the drivers? It is best practice to avoid NumberLong is I can fit the value inside 32-bit? Will I save a lot of data and index space if I convert all NumberLongs to basic numbers?

  • UIImageView is clipping a pixel of the bottom of my UIImage...?

    - by akaii
    I'm not sure what might be causing this, but UIImageView occasionally clips off about a pixel or 2 from the bottom of some square/rectangular UIImages I'm using as subviews for UITableViewCells. These UIImageViews are well within the borders of the cell, so it shouldn't be due to cliptobounds. There seems to be no consistency or pattern to which images are being clipped, nor when they're clipped, other than that it only happens to (or is only noticable in) square/rectangular icons, and only ones that are parented to UITableViewCells (or their subclasses). I'm having trouble reproducing the problem consistently, which is why I haven't posted any code this time. Has anyone encountered something similar to this before? I've encountered a similar bug that involved floating point values for origin/size being interpreted weirdly... but that doesn't seem to be the cause of this particular problem. I don't need a specific solution at this point, I'm just making sure I haven't missed any well-known bugs or documented problems that involve UIImageView.
