• int[] to string c#

  - by Robin Webdev

  Hi I'm developing an client application in C# and the server is written in c++ the server uses: inline void StrToInts(int *pInts, int Num, const char *pStr) { int Index = 0; while(Num) { char aBuf[4] = {0,0,0,0}; for(int c = 0; c < 4 && pStr[Index]; c++, Index++) aBuf[c] = pStr[Index]; *pInts = ((aBuf[0]+128)<<24)|((aBuf[1]+128)<<16)|((aBuf[2]+128)<<8)|(aBuf[3]+128); pInts++; Num--; } // null terminate pInts[-1] &= 0xffffff00; } to convert an string to int[] in my c# client i recieve: int[4] { -14240, -12938, -16988, -8832 } How do I convert the array back to an string? I don't want to use unsafe code (e.g. pointers) Any of my tries resulted in unreadable strings.

• C++ MFC add combo box string item from a widget ID

  - by OzBarry

  I've added a combo box in the gui editor in MSVC 2010 pro in my MFC project. I have a list of strings I am grabbing from an external source and want to add them to my combo box. I've searched for a while, and every post seems to suggest I need to use the CComboBox class, however, I have no idea how to get the class variable from the resource ID of the combobox element in the gui editor. In summary, how do I add a string to my combo box, either using a macro (like CB_ADDSTRING(RESOURCE_ID, "my string");) or using CComboBOx (something like CComboBox::GetObject(RESOURCE_ID)->AddString("blah");). I do not do much win32 api/mfc programming, and just started fiddling around with it.

• iPhone FTP Connection

  - by collin

  I am working on an iPhone app for a client that needs to be able to manipulate directories on an arbitrary FTP server. Does anybody know of any FTP libraries, frameworks, sample code that can remove directories from an FTP server? NOTE I have thoroughly researched CFFTP and the SimpleFTP Sample code provided by Apple and it only supports half of the FTP protocol(I don't know why there is only half of the implementation).

• Convert Military time to string representation

  - by RRUZ

  I have an column declarated as int (called HourMil) wich store the time in military format. i need convert this values to an formated string (HH:MM) example HourMil = 710 -> must be 07:10 HourMil = 1305 -> must be 13:05 Actually i am using this code (and works ok) for convert the column HourMil to the string representation. SELECT SUBSTRING(LEFT('0',4-LEN(CAST(HourMil AS VARCHAR)))+CAST(HourMil AS VARCHAR),1,2)+':'+SUBSTRING(LEFT('0',4-LEN(CAST(HourMil AS VARCHAR)))+CAST(HourMil AS VARCHAR),3,2) FROM MYTABLE but I think this code can be improved.

• MVC for a desktop application, connection a view/controller pair with another one

  - by lcf

  Hello. I've had mostly experience with "server-side" mvc frameworks very popular in different languages like ASP.NET MVC or Zend Framework for php, Spring for Java etc. Some of them are also possible to use for desktop applications development but I never tried that. I fully understand that design patterns should not limit implementation, they should generally provide ideas and common rules that can be differently implemented. Now I'm playing with one of those mvc frameworks for usual Desktop Applications development (it does not have many tutorials or a decent quickstart) and I have some questions regarding to the mvc paradigm. Here is one of them: What are common ways to link different views / controllers? If I click a button, special controller for that button dispatches the event that is generated, does something with the model, changes view state. But what if I need to interact with another view? Like, when I click on a button, it changes a model, but also I need to open another window or change state of another window (hiding a button on another window let's say...), without changing actually the model. What are common ways here to address this? Should my first controller generate an event for the second controller (or second view)? Or should the second controller be handling events from first view? Some links or examples for any languages/frameworks would be really helpful, thanks!

• C# Sql Connection Best Practises 2013

  - by Pete Petersen

  With the new year approaching I'm drawing up a development plan for 2013. I won't bore you with the details but I started thinking about whether the way I do things is actually the 'correct' way. In particular how I'm interfacing with SQL. I create predominantly create WPF desktop applications and often some Silverlight Web Applications. All of my programs are very Data-Centric. When connecting to SQL from WPF I tend to use Stored Procedures stored on the server and fetch them using ADO.NET (e.g. SQLConnection(), .ExecuteQuery()). However with Silverlight I have a WCF service and use LINQ to SQL (and I'm using LINQ much more in WPF). My question is really is am I doing anything wrong in a sense that it's a little old fashioned? I've tried to look this up online but could find anything useful after about 2010 and of those half were 'LINQ is dead!' and the other 'Always use LINQ' Just want to make sure going forward I'm doing the right things the right way, or at least the advised way :). What principles are you using when connecting to SQL? Is it the same for WPF and Silverlight/WCF?

• Where to store: User connection information?

  - by TomTom

  ;) I am writing a .NET application wher ethe user connects to a given server. ALl information within the application is stored in the server. But I want / need to store the following information for the user: The server he connected to last The username he used to connect last (and no, no password, never ever). Any idea where to store this best? the application config file is not sensible (user != admin, application.config is write protected for him). So, my options are: In the registry. 2 keys under my own subkey. In a sort of ini file, stored in the user's data directory (AppData). This would possibly also allow later expansion (into like saving more information, some of which may not fit into the registry). Anyone a tip? Other alternatives? I tend so far to go for the AppData directory with my own subfolder - simply because it is a nice preparation for later to keep like a local copy of configuration etc.

• What is wrong in this json string?

  - by bala3569

  My json string looks like this, {"id" : "38","heading" : "Can you also figure out how to get me back the 10 hours I sp.....","description" : "Im having a very similar problem with the Login control - again it always generates a default style containing border -collapse -only in this case .....","img_url" : "~/EventImages/ EventImages1274014884460.jpg","catogory" : "News","doe" : "15-05-2010 "} But get the error, unterminated string literal.... EDIT: I used this but it didn't work, var newjson = cfreturn( """" & ToString( HfJsonValue ).ReplaceAll( "(['""\\\/\n\r\t]{1})", "\\$1" ) & """" ) ; var jsonObj = eval('(' + newjson + ')'); Error: missing ) after argument list Source Code: var newjson = cfreturn( """" & ToString( HfJsonValue ).ReplaceAll( "(['""\\\/\n\r\t]{1})", "\\$1" ) & """" ) ;

• replace nth occurence of string in each line of a text file

  - by dnkb

  I have large text files with space delimited strings (2-5). The strings can contain "'" or "-". I'd like to replace say the second space with a pipe. What's the best way to go? Using sed I was thinking of this: sed -r 's/(^[a-z'-]+ [a-z'-]+\b) /\1|/' filename.txt Any other/better/simpler ideas? Thank you

• Connection between Properties of Entities in Data Oriented Design

  - by sharethis

  I want to start with an example illustrating my question. The following way it is done in the most games. class car { vec3 position; vec3 rotation; mesh model; imge texture; void move(); // modify position and rotation void draw(); // use model, texture, ... }; vector<car> cars; for(auto i = cars.begin(); i != cars.end(); ++i) { i->move(); i->draw(); } Data oriented design means to process the same calculation on the hole batch of data at once. This way it takes more advantage out of the processor cache. struct movedata { vec3 position; vec3 rotation; }; struct drawdata { mesh model; imge texture; }; vector<movedata> movedatas; vector<drawdata> drawdatas; for(auto i = movedatas.begin(); i != movedatas.end(); ++i) { // modify position and rotation } for(auto i = drawdatas.begin(); i != drawdatas.end(); ++i) { // use model, texture, ... } But there comes a point where you need to find other properties according to an entity. For example if the car crashes, I do not need the drawdata and the movedata any more. So I need to delete the entries of this entity in all vectors. The entries are not linked by code. So my question is the following. How are properties of the same entity conceptually linked in a data oriented design?

• appending text to all files that starts with a string

  - by learner135

  How do I append a string to all the files in a directory that starts with a particular string? I tried, cat mysig >> F* But instead of appending contents of mysig to all files starting with F, it creates a file named "F*". Obviously wildcard doesn't seem to work. Any alternatives? Thanks in advance. Edit: Also how do I delete this newly created file "F*" safely?. Using rm F* would delete all the files starting with F which I wouldn't want.

  Hello I have created Qt tree control( and its nodes ) in different thread than the main thread. In the main thread I want to show context menu for the clicked node, so I am connectiong the actions in the menu with appropriate slots in the main thread. The connect function returns true , but slot is never executed. If I explicitly say in connect function that this is Qt :: DirectConnection then everything works fine. Why is this ? I I create my tree in main thread, everything also works fine , without having to say that this is Qt::DirectConnection .

• Using nsIZipWriter or other to compress a string as a string?

  - by Daniel

  I need to be able to take a javascript string, compress it using any fast and available means and get back a binary string/blob. Background: The extension I'm developing needs to send various large content to my server. It does this conveniently by dynamically creating a form, adding fields to the form and posting it. Some of these fields are just too big bandwidth wise for multiple use. I'd like to be able to compress them before adding them and then maybe base64'ing them if the characters cause a problem in the message. Any ideas? I could use nsiZipWriter with temporary files on disk but that is quite ugly and probably sluggish.

• Format MySQL code inside PHP string

  - by JohnA

  Is there any program IDE or not that can format MySQL code inside PHP string e.g. I use PHPStorm IDE and it cannot do it. It does that for PHP and MYSQL but not for MYSQL inside php string. I am ready to use new IDE because now i have to manually format hundreds of database requests that are one line and not readable. Only criteria for my choice is that ide can do that automatically. <?php ... $request1 = "select * from tbl_admin where admin_id= {$_SESSION['admin_id']} and active= 1 order By admin_id Asc"; ... ?> should become <?php ... $request1 = "SELECT * FROM tbl_admin WHERE admin_id = {$_SESSION['admin_id']} AND active = 1 ORDER BY admin_id ASC"; ... ?>

• Reading bytes from JavaScript string

  - by Jan

  I have a string containing binary data in JS. Now I want to read, for example, an integer from it. So I get the first 4 characters, use charCodeAt, do some shifting etc. to get an integer. Problem is that strings in JS are UTF-16 (instead of ASCII) and charCodeAt often returns values higher than 256. The Mozilla reference states that "The first 128 Unicode code points are a direct match of the ASCII character encoding." (what about ASCII values 128?) How can I convert the result of charCodeAt to an ASCII value? Or is there a better way to convert a string of four characters to a 4 byte integer?

• Connection Timeout Linked Server

  - by Wade73

  I have created a linked server from one SQL Server 2005 to Another 2005. When I run an update query through the SQL Server Management Studio (SSMS), it runs in under a second. If I run the query through a asp webpage it times out. I ran SQL Profiler to see if I noticed anything as well as the Activity Monitor in SSMS and all I found was that a lock was being created (Wait type LOCK_M_U), but I can't find what is locking it. Any help would be appreciated. Wade
