• How do you open a second WPF window without creating a new one.

  - by Daniel

  In the program I am trying to build, I have a menu button that opens a second window. The user puts information into the second window, presses the "Done" button, and the information is transfered into the main window. The problem I am having is opening the second window. I have both windows build in xaml files in Visual Studio but I can't find a way to show the second window. Using "Window window = new Window" does not fit my needs because 1) I already have the second window built and 2) I have tried this and I cannot figure out how to add children to the window; there is no window.children nor any grid to put the children into. Thank you in advance!

• How to find which existing .NET solutions contain a project?

  - by Daniel Daranas

  I am exploring a structure of folders with C# projects such as the following: Projects ProjectA ProjectB ProjectC ProjectD Scattered around in the same folders as the .csproj files, there are several solution (.sln) files. Is there a fast way to find all the solutions that contain ProjectD.vsproj? I can open them one by one and see what they contain, but I would like a feature such as "find all the solutions containing this project".

• get next available integer using LINQ

  - by Daniel Williams

  Say I have a list of integers: List<int> myInts = new List<int>() {1,2,3,5,8,13,21}; I would like to get the next available integer, ordered by increasing integer. Not the last or highest one, but in this case the next integer that is not in this list. In this case the number is 4. Is there a LINQ statement that would give me this? As in: var nextAvailable = myInts.SomeCoolLinqMethod(); Edit: Crap. I said the answer should be 2 but I meant 4. I apologize for that! For example: Imagine that you are responsible for handing out process IDs. You want to get the list of current process IDs, and issue a next one, but the next one should not just be the highest value plus one. Rather, it should be the next one available from an ordered list of process IDs. You could get the next available starting with the highest, it does not really matter.

• What kind of work benifits from OpenCL

  - by Daniel

  Hey All First of all: I am well aware that OpenCL does not magically make everything faster I am well aware that OpenCL has limitations So now to my question, i am used to do different scientific calculations using programming. Some of the things i work with is pretty intense in regards to the complexity and number of calculations. SO i was wondering, maybe i could speed things up bu using OpenCL. So, what i would love to hear from you all is answers to some of the following [bonus for links]: *What kind of calculations/algorithms/general problems is suitable for OpenCL *What is the general guidelines for determining if some particular code would benefit by migration to OpenCL?

• DIV inside TD to make it appear correctly

  - by Daniel Svensson

  Hi, I have a <table> generated from code-behind and now facing a problem. In one of the TD i need to have a DIV that is setup with JQuery so that when i click a link the DIV slideToggles. Now i need the TD belonging to that TR not to expand the TR. To solve this i have used an old trick that is to place the JQuery DIV inside another surrounding DIV with height 1px and make the TR not expanding with the heigth of the DIV that slides out. In IE the sliding DIV is partially under the table and in Firefox the DIV appears over the table but it's trasparent, the text from the data in the table shows thru. I have tried to alter the Z-index in various ways but it's no good. Anyone that has an idea or alternatively solution that has worked for them. HtmlGenericControl containerDiv = new HtmlGenericControl("div"); containerDiv.ID = "containerDiv"; containerDiv.Style.Add(System.Web.UI.HtmlTextWriterStyle.Width, "100%"); containerDiv.Style.Add(System.Web.UI.HtmlTextWriterStyle.Height, "1px"); containerDiv.Style.Add(System.Web.UI.HtmlTextWriterStyle.ZIndex, "999"); HtmlGenericControl innerDiv = new HtmlGenericControl("div"); innerDiv.ID = System.Guid.NewGuid().ToString() + "_annualDiv"; inner.Style.Add(System.Web.UI.HtmlTextWriterStyle.Width, "100%"); innerDiv.Style.Add(System.Web.UI.HtmlTextWriterStyle.Height, "300px"); innerDiv.Style.Add(System.Web.UI.HtmlTextWriterStyle.ZIndex, "1000"); innerDiv.Style.Add(System.Web.UI.HtmlTextWriterStyle.BorderStyle, "solid"); innerDiv.Style.Add(System.Web.UI.HtmlTextWriterStyle.BorderColor, "Black"); innerDiv.Style.Add(System.Web.UI.HtmlTextWriterStyle.BorderWidth, "1px"); innerDiv.Style.Add(System.Web.UI.HtmlTextWriterStyle.BackgroundColor, "white"); innerDiv.InnerHtml = "Here is a list of links coming later"; conDiv.Controls.Add(innerDiv);

• What is Java Message Service (JMS) for?

  - by Daniel

  I am currently evaluating JMS and I don't get what I could use it for. Currently, I believe this would be a Usecase: I want to create a SalesInvoice PDF and print it when an SalesOrder leaves the Warehouse, so during the Delivery transaction I could send a transactional print request which just begins when the SalesOrder transaction completes successfully. Now I found out most JMS products are standalone server. Why would a need a Standalone Server for Message Processing, vs. e.g. some simple inproc processing with Quartz scheduler? How does it interact with my application? Isn't it much too slow? What are Usecases you already implemented successfully?

• Why do I have to explicitly cast sometimes for varargs?

  - by Daniel Lew

  I've got a Class that uses reflection a lot, so I wrote a method to help out: private <T> T callMethod(String methodName, Class[] parameterTypes, Object[] args) { try { Class c = mVar.getClass(); Method m = c.getMethod(methodName, (Class[]) parameterTypes); return (T) m.invoke(mVar, args); } // Insert exception catching here [...] } This worked well for any method that had parameters, however I had to explicitly cast parameterTypes to Class[] in order for this to work for methods with no parameters (e.g., callMethod('funName', null, null);). I've been trying to figure out why this is the case. It seems to me that if parameterTypes, when null, had no concept of what type it is (Class[]), then I'd need to cast it for getMethod(). But if that's the case, why is getMethod() able to tell the difference between null, and (Class[]) null when the method is invoked?

• PHP Foreach statement issue. Multiple rows are returned

  - by Daniel Patilea

  I'm a PHP beginner and lately i've been having a problem with my source code. Here it is: <html> <head> <title> Bot </title> <link type="text/css" rel="stylesheet" href="main.css" /> </head> <body> <form action="bot.php "method="post"> <lable>You:<input type="text" name="intrebare"></lable> <input type="submit" name="introdu" value="Send"> </form> </body> </html> <?php //error_reporting(E_ALL & ~E_NOTICE); mysql_connect("localhost", "root", "") or die(mysql_error()); mysql_select_db("robo") or die(mysql_error()); $intrebare=$_POST['intrebare']; $query = "SELECT * FROM dialog where intrebare like '%$intrebare%'"; $result = mysql_query($query) or die(mysql_error()); $row = mysql_fetch_array($result) or die(mysql_error()); ?> <div id="history"> <?php foreach($row as $rows){ echo "<b>The robot says: </b><br />"; echo $row['raspuns']; } ?> </div> It returns me the result x6 times. This problem appeared when I've made that foreach because I wanted the results to stuck on the page one by one after every sql querry. Can you please tell me what seems to be the problem? Thanks!

• 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.

• Is O_LARGEFILE needed just to write a large file?

  - by Daniel Trebbien

  Is the O_LARGEFILE flag needed if all that I want to do is write a large file (O_WRONLY) or append to a large file (O_APPEND | O_WRONLY)? From a thread that I read titled "Cannot write 2gb index file" on the CLucene-dev mailing list, it appears that O_LARGEFILE might be needed to write large files, but participants in that discussion are using O_RDWR, not O_WRONLY, so I am not sure.

• How to skip certain tests with Test::Unit

  - by Daniel Abrahamsson

  In one of my projects I need to collaborate with several backend systems. Some of them somewhat lacks in documentation, and partly therefore I have some test code that interact with some test servers just to see everything works as expected. However, accessing these servers is quite slow, and therefore I do not want to run these tests every time I run my test suite. My question is how to deal with a situation where you want to skip certain tests. Currently I use an environment variable 'BACKEND_TEST' and a conditional statement which checks if the variable is set for each test I would like to skip. But sometimes I would like to skip all tests in a test file without having to add an extra row to the beginning of each test. The tests which have to interact with the test servers are not many, as I use flexmock in other situations. However, you can't mock yourself away from reality. As you can see from this question's title, I'm using Test::Unit. Additionally, if it makes any difference, the project is a Rails project.

• Git 1.7.10 asks me for github username and password

  - by Daniel Ruf

  Since I have the new version it doesnt ask me anymore for the password I set in my ssh key file. It asks now directly for a github username and password when I push every time. Is this a new feature of git or changed it in the past or is there something what changed on github? I tried to authenticate using ssh and the email and password from my ssh ke file and it worked. Github changed to smartftp and also changed the instructions for setting up repos https://github.com/blog/1104-credential-caching-for-wrist-friendly-git-usage https://help.github.com/articles/create-a-repo Saw it later, they use now https instead of the git protocol

• Display web page from another site in asp page.

  - by Daniel

  hi all, Our customer has a requirement to extend the functionality of their existing large government project. It is an ASP.NET 3.5 (recently upgraded from 2.0) project. The existing solution is quite a behemoth that is almost unmaintainable so they have decided that they want to provide the new functionality by hosting it on another website that is shown within the existing website. As to how this is best to be done I'm not quite sure right now and if there is any security issues preventing it or that need to be considered. Essentially the user would log on to the existing web site as normal and when cliicking on a certain link the page would load as normal with some kind of frame or control that has within it the contents of the page from the other site. IE. They do not want to simply redirect to the other site they want to show it embedded within the current one such that the existing menus etc are still available. I believe if information needed to be passed to the embedded page it would be done using query strings as I'm not sure if there is even another way to accomplish this. Can anyone give me some pointers on where to start at looking to implement this or any potential pitfalls I should be aware of. Thanks

• Big time Leaking in Objective-C Category

  - by Daniel Amitay

  I created a custom NSString Category which lets me find all strings between two other strings. I'm now running into the problem of finding that there are a lot of kBs leaking from my script. Please see code below: #import "MyStringBetween.h" @implementation NSString (MyStringBetween) -(NSArray *)mystringBetween:(NSString *)aString and:(NSString *)bString; { NSAutoreleasePool *autoreleasepool = [[NSAutoreleasePool alloc] init]; NSArray *firstlist = [self componentsSeparatedByString:bString]; NSMutableArray *finalArray = [[NSMutableArray alloc] init]; for (int y = 0; y < firstlist.count - 1 ; y++) { NSString *firstObject = [firstlist objectAtIndex:y]; NSMutableArray *secondlist = [firstObject componentsSeparatedByString:aString]; if(secondlist.count > 1){ [finalArray addObject:[secondlist objectAtIndex:secondlist.count - 1]]; } } [autoreleasepool release]; return finalArray; } @end I admit that I'm not super good at releasing objects, but I had believed that the NSAutoreleasePool handled things for me. The line that is leaking: NSMutableArray *secondlist = [firstObject componentsSeparatedByString:aString]; Manually releasing secondlist raises an exception. Thanks in advance!

• A better name for INeedSomething... ?

  I was trying pick a name for an interface through which I can pass something into an object like: If the object is INeedX then SetX(some x) method will be called; If the object is INeedY then SetY(some y) method will be called; and so on. (funny as hell, I know :) ) I try to find a different name for this kind of interfaces but I can't figure this out. Does anybody have an idea how to name the INeedSomething interface ?

• Key logger wont record key strokes without console

  - by Daniel Gopar

  I created a small basic key logger in C++. For some reason when I compile and run the program with the console displayed, it will record every key stroke I make in whatever program I am using such as a browser and store it in a text file. However when I make it so that it WON'T display a console window, it will not record anything and it's just a process in the background doing nothing. Here is the link to my code: http://pastebin.com/4wqQyLJ9 The function that is giving me trouble with hiding the console, is the Stealth() function. Any suggestions, tips or hints will be helpful. Thanks.

• Rewriting simple C# nested class

• Call Single StrConn from Multiple Pages

  I have a ocnnection to SQL Server set up in my vba code. The format is: strConn = "ODBC;Driver=SQL;Server=SQL1;Database=DB1;Uid=1;Pwd=1" I have this in 4 sheets, but there will be times when I will want to change it to call from SQL2 or SQL3, and instead of changing the code on each sheet 4 times, I want to change it only once. Is there a way to set up that line to run by calling it from somewhere else or by passing in a string into the ""?
