  • For Qt 4.6.x, how to auto-size text to fit in a specified width?

    - by darenchow
    Inside of my QGraphicsRectItem::paint(), I am trying to draw the name of the item within its rect(). However, for each of the different items, they can be of variable width and similarly names can be of variable length. Currently I am starting with a maximum font size, checking if it fits and decrementing it until I find a font size that fits. So far, I haven't been able to find a quick and easy way to do this. Is there a better, or more efficient way to do this? Thanks! void checkFontSize(QPainter *painter, const QString& name) { // check the font size - need a better algorithm... this could take awhile while (painter->fontMetrics().width(name) > rect().width()) { int newsize = painter->font().pointSize() - 1; painter->setFont(QFont(painter->font().family(), newsize)); } }

  • Problem in passing arrays from C# to C++

    - by Rakesh K
    Hi, I have an application in which I need to pass an array from C# to a C++ DLL. What is the best method to do it? I did some search on Internet and figured out that I need to pass the arrays from C# using ref. The code for the same: status = IterateCL(ref input, ref output); The input and output arrays are of length 20. and the corresponding code in C++ DLL is IterateCL(int *&inArray, int *&outArray) This works fine for once. But if I try to call the function from C# in a loop the second time, the input array in C# is showing up as an array of one element. Why is this happening and please help me how I can call this function iteratively from C#. Thanks, Rakesh.

  • How to sum up an array of integers in C#

    - by Filburt
    Is there a better shorter way than iterating over the array? int[] arr = new int[] { 1, 2, 3 }; int sum = 0; for (int i = 0; i < arr.Length; i++) { sum += arr[i]; } clarification: Better primary means cleaner code but hints on performance improvement are also welcome. (Like already mentioned: splitting large arrays). It's not like I was looking for killer performance improvement - I just wondered if this very kind of syntactic sugar wasn't already available: "There's String.Join - what the heck about int[]?".

  • By passing div id, can i change target of text replacement?

    - by crosenblum
    I am using the code below to replace text inside a div. But I need to loop through a specific div, instead of everything on the page, that is the div's text nodes... I just do not understand how to refer to the div in the code below. (function (parent) { var childs = parent.childNodes; // if there are children to this if (childs && childs.length) { // loop through each text node for (var i = 0, node; node = childs[i]; i++) {

  • To remove garbage characters from a string using regex...

    Hi I want to remove characters from a string other then a-z, and A-Z. Created following function for the same and it works fine. public String stripGarbage(String s) { String good = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz"; String result = ""; for (int i = 0; i < s.length(); i++) { if (good.indexOf(s.charAt(i)) >= 0) { result += s.charAt(i); } } return result; } Can anyone tell me a better way to achieve the same. Probably regex may be better option. Regards Harry

  • How can I change or remove HttpRequest input arguments in a HttpModule

    - by Eric Gunn
    Is it possible to change or remove http request form inputs in an httpmodule? My goal is to create a security IHttpmodule that will check the request for reasonable values, such as limits on acceptable input and query parameter length, or use the AntiXSS Sanitizer to remove threats, log potential hack attempts, etc. before a request is passed on to a processor. Because this is a cross cutting concern I'd prefer to find a solution that applies to all requests and affects all ways request values could be accessed, Reqest.Form, Action(model), Action(FormCollection), HttpContext.Current.Request.Form, etc. I'm using MVC and have considered creating custom model binders to clean the data before creating the model instance. But that would be application specific, require remembering to register every model binder and only apply to Action(model).

  • How to add values to a JSON object?

    - by Damiano
    Hello everybody, I have created an array with: var msg = new Array(); then, I have a function that add values to this array, this function is: function add(time, user, text){ var message = [time, user, text]; if (msg.length >= 50) msg.shift(); msg.push(message); } As you can see, if the array has 50 or more elements I remove the first with .shift(). Then I add an array as element. Ok, the code works perfectly, but now I have to loop the msg array to create a JSON obj. The JSON object should has this format: var obj = [ {'time' : time, 'user' : user, 'text' : text}, {'time' : time, 'user' : user, 'text' : text}, {'time' : time, 'user' : user, 'text' : text} ] I mean...i have to loop msg array and then store all the values inside the JSON object. I do not know how to "concatenate" the element of the array inside json obj. Could you help me? Thank you very much in advance!

  • SQL decimal conversion error

    - by jakesankey
    Hey, my app parses numerous txt files in a directory that are almost all formatted identically, then inserts the values into columns of my sql db. However, there are a few files that the app has come across where a value is 'blank' instead of '0.0', so the application fails stating that it cannot convert that value to numeric. Is there a way I could change the following code to say what says AND also add 'IF value is blank, then import 0.0 instead? foreach (SqlParameter parameter in insertCommand.Parameters) { parameter.Value = null; } string[] values = line.Split(new[] { ',' }); for (int i = 0; i < values.Length - 1; i++) { // if (i = "" || i = null) continue; SqlParameter param = insertCommand.Parameters[i]; if (param.DbType == DbType.Decimal) { decimal value; param.Value = decimal.TryParse(values[i], out value) ? value : 0; } else { param.Value = values[i]; } }

  • Confused about GNU `sort(1)` of a numerical sub field

    - by Chen Levy
    I wish to sort a space separated table, with the numerical value that found on the 2nd field. I can assume that the 2nd field is always fooN but the length of N is unknown: antiq. foo11 girls colleaguing foo2 Leinsdorf Cousy foo0 Montgomeryville bowlegged foo1 pollack Chevrier foo10 ill-conceived candlebomb foo3 seventieths autochthony foo101 re-enable beneficiate foo100 osteometric I read man sort(1) and played with all sort of options. On my system I found the line: sort -n -k2.5 table to work. My question is why? According to the man page: -k, --key=POS1[,POS2] start a key at POS1, end it at POS 2 (origin 1) ... POS is F[.C][OPTS], where F is the field number and C the characterposition in the field. OPTS is one or more single-letter ordering options, which override global ordering options for that key. If no key is given, use the entire line as the key. So why sort -n -k2.4 table don't work and sort -n -k.5 does?

  • How should I handle searching through byte arrays in Java?

    - by Zombies
    Preliminary: I am writting my own httpclient in Java. I am trying to parse out the contents of chunked encoding. Here is my dilema: Since I am trying to parse out chunked http transfer encoding with a gzip payload there is a mix of ascii and binary. I can't just take the http resp content and convert it to a string and make use of StringUtils since the binary data can easily contain nil characters. So what I need to do is some basic things for parsing out each chunk and its chunk length (as per chunked transfer/HTTP/1.1 spec). Are there any helpful ways of searching through byte arrays of binary/part ascii data for certain patterns (like a CR LF) (instead of just a single byte) ? Or must I write the for loops for this?

  • C#: Why am I getting "the process cannot access the file * because it is being used by another proce

    - by zxcvbnm
    I'm trying to convert bmp files in a folder to jpg, then delete the old files. The code works fine, except it can't delete the bmp's. DirectoryInfo di = new DirectoryInfo(args[0]); FileInfo[] files = di.GetFiles("*.bmp"); foreach (FileInfo file in files) { string newFile = file.FullName.Replace("bmp", "jpg"); Bitmap bm = (Bitmap)Image.FromFile(file.FullName); bm.Save(newFile, ImageFormat.Jpeg); } for (int i = 0; i < files.Length; i++) files[i].Delete(); The files aren't being used by another program/process like the error indicates, so I'm assuming the problem is here. But to me the code seems fine, since I'm doing everything sequentially. This is all that there is to the program too, so the error can't be caused by code elsewhere.

  • Using VirtualMode on a DataGridView when the number of rows/columns isn't known

    - by Nathan Baulch
    I need to display an unknown length sequence of dictionaries with unknown keys efficiently in a data grid. This sequence is the result of a potentially slow LINQ query that could contain any number of results. At first I thought that VirtualMode on DataGridView was what I was looking for but it appears that the number of rows and columns must be known upfront. I tried adding a single row and column then adding more as needed from the CellValueNeeded event but this doesn't work. Is this even possible with VirtualMode? Or do I need to estimate how many rows are visible on the screen and manually build up the rows/columns? And if so, how do I ensure that a vertical scrollbar is present and react appropriately when a user uses it?

  • How to validate a form with jQuery?

    - by vlad
    I tried to find the answer in other questions but actually nothing worked -.- Somehow I hate JavaScript ... Anyway! My Code looks like: function validate() { if ($(":input").length == 0) { $(":input").addClass("notvalid"); return false; } else { $(":input").removeClass("notvalid"); return true; } return true; } $(":input").blur(validate()); $(":input").keyup(validate()); $("#customForm").submit(function(){ if(validate()){ return true; } else { return false; } }); I just want to test every tag to be not empty. The test should be done when the focus is lost or after every key type. And of course after the submit button has been clicked. It doesn't work. Firefox error console says something like: unknown pseudoclass or pseudoelement 'input'. What does this mean?

  • Java how to copy part of a file

    - by user3479074
    I have to read a file and depending of the content of the last lines, I have to copy most of its content into a new file. Unfortunately I didn't found a way to copy first n lines or chars of a file in java. The only way I found, is copying the file using nio FileChannels where I can specifiy the length in bytes. However, therefore I would need to know how many bytes the stuff I read needed in the source-file. Does anyone know a solution for one of these problems?

  • OracleDataAdapter returns no rows, but the query string works in SQLDeveloper

    - by belzebu
    visual studion 2008 oracle db 11.1.0.7 oracle client for .NET I have a relatively simple query, that selects the rows from across multiple tables (up to 4) using joins. OracleDataAdapter returns no rows for the only dataset's table, but if I copy and paste that query in SQLDeveloper then I get the desired results. I can get the data from other tables using the adapter with no problem, but it seems like it struggles with the bit longer selection query (string length is ~ 300 (not that much at all)) Connection string for the connection is 100% correct. Any ideas? thank you...

  • nHibernate Linq Projection

    - by Craig
    I am using the version 1.0 release of Linq for nHibernate. When I run the following linq statements I receive the error not a single-length projection: Surname I can find very few references to this on the web and looking into the source it says it should never occur! ClientID is a Int type and Surname is a string. When I comment out all the string fields in the projection and just leave ClientID it runs ok, but as soon as I add surname back it errors. var context = m_ClientRepository.Linq; var result = (from client in context from address in client.Addresses from contact in client.Contacts where client.Surname.StartsWith(surname) && client.GivenName.StartsWith(givenName) && contact.Value.StartsWith(phoneNumber) group client by new { client.ClientID, client.Surname, client.GivenName } into clientGroup select new ClientSearchDTO() { ClientID = clientGroup.Key.ClientID, Surname = clientGroup.Key.Surname, GivenName = clientGroup.Key.GivenName, Address = clientGroup.Max(x => x.Addresses.FirstOrDefault().Address), PhoneNumber = clientGroup.Max(x => x.Contacts.FirstOrDefault().Value) }) .Skip(Paging.FirstRecord(pageNumber)) .Take(5);

  • just-in-time list

    - by intuited
    I'd like to know if there is a class available, either in the standard library or in pypi, that fits this description. The constructor would take an iterator. It would implement the container protocol (ie _getitem_, _len_, etc), so that slices, length, etc., would work. In doing so, it would iterate and retain just enough values from its constructor argument to provide whatever information was requested. So if jitlist[6] was requested, it would call self.source.next() 7 times, save those elements in its list, and return the last one. This would allow downstream code to use it as a list, but avoid unnecessarily instantiating a list for cases where list functionality was not needed, and avoid allocating memory for the entire list if only a few members ended up being requested. It seems like a pretty easy one to write, but it also seems useful enough that it's likely that someone would have already made it available in a module.

    Hi all, I'm having a scrollview as the detailedview of tableview cell. There are multiple views on the detailedview like labels, buttons etc. which I'm creating through interface builder. What I'm creating through interface builder is static. I'm putting everything on a view of height 480. A label on my detailedview is having dynamic text which can extend to any length. The problem is that I need to set the scrollview's content size for which I need its height. How shall I set scrollview's height provided the content is dynamic?
