  • java question: Is it a method?

    - by Stefan
    Hello, I'm no Java guy, so I ask myself what this means: public Button(Light light) { this.light = light; } Is Button a method? I ask myself, because it takes an input parameter light. But if it was a method, why would it begin with a capital letter and has no return data type? Here comes the full example: public class Button { private Light light; public Button(Light light) { this.light = light; } public void press() { light.turnOn(); } } I know, this question is really trivial. However, I have nothing to do with Java and haven't found a description for the Button thing above. I'm just interested.

  • Best way to manage a header navigation menu from within a template?

    - by Stefan Kendall
    I'm looking to put navigation in my GSP template, and I would like to set the active class on the navigation elements for each respective page. What's the best way to do this? I have several .gsp views merging with a single template that looks like this: <div id="bd" role="main"> <div role="navigation" class="yui-g"> <ul id="nav"><a href="index.gsp"><li class="active">Home</li></a><a href = "products.gsp"><li>Products</li></a><a href = "contacts.gsp"><li>Contact</li></a></ul> </div> <g:layoutBody/> </div>

  • Grails gdoc editor support (esp IntelliJ)

    - by Stefan
    Since Grails 1.2 there's a documentation engine included: gdoc. The documentation's syntax is based on the Textile format. Is there some editor support for this? My first choice would be a plugin for IntelliJ, second option on for vim or gedit. Any hints welcome. I am totally a aware that the format is very simple by itself but having code coloring and content assist would be really nice.

  • C#: Drag & Drop with right mouse button

    - by stefan.at.wpf
    Hello, I'd like to do Drag & Drop with the right mouse button instead with the left one. However calling DragDrop.DoDragDrop() from MouseRightButtonDown instead of MouseLeftButtonDown doesn't do the job - DragDrop.DoDragDrop looks for mouse movements while holding down the left mouse button. Any idea how to realise Drag & Drop using the right mouse button? Thanks for any hint!

  • Problem with passing parameters to SQL procedure using VBA

    - by Stefan Åstrand
    Hi, I am trying to pass @intDocumentNo and @intCustomerNo to a stored procedure using VBA but only @intCustomerNo is updated in dbo.tblOrderHead. I don't think the problem is with the procedure because if I enter the values manually it runs properly. What am I doing wrong? VBA Code: Private Sub intCustomerNo_Click() Dim cmdCommand As New ADODB.Command With cmdCommand .ActiveConnection = CurrentProject.Connection .CommandType = adCmdStoredProc .CommandText = "uspSelectCustomer" '@intDocumentNo .Parameters("@intDocumentNo").Value = Forms![frmSalesOrder].[IntOrderNo] '@intCustomerNo .Parameters("@intCustomerNo").Value = Me![intCustomerNo] .Execute End With DoCmd.Close Forms![frmSalesOrder].Requery End Sub Procedure: UPDATE dbo.tblOrderHead SET dbo.tblOrderHead.intCustomerNo = @intCustomerNo , dbo.tblOrderHead.intPaymentCode = dbo.tblCustomer.intPaymentCode, dbo.tblOrderHead.txtDeliveryCode = dbo.tblCustomer.txtDeliveryCode, dbo.tblOrderHead.txtRegionCode = dbo.tblCustomer.txtRegionCode, dbo.tblOrderHead.txtCurrencyCode = dbo.tblCustomer.txtCurrencyCode, dbo.tblOrderHead.txtLanguageCode = dbo.tblCustomer.txtLanguageCode FROM dbo.tblOrderHead INNER JOIN dbo.tblCustomer ON dbo.tblOrderHead.intCustomerNo = dbo.tblCustomer.intCustomerNo AND dbo.tblOrderHead.intOrderNo = @intDocumentNo

  • Disposing ActiveX resources owned by another thread

    - by Stefan Teitge
    I've got a problem problem with threading and disposing resources. I've got a C# Windows Forms application which runs expensive operation in a thread. This thread instantiates an ActiveX control (AxControl). This control must be disposed as it uses a high amount of memory. So I implemented a Dispose() method and even a destructor. After the thread ends the destructor is called. This is sadly called by the UI thread. So invoking activexControl.Dispose(); fails with the message "COM object that has been separated from its underlying RCW", as the object belongs to another thread. How to do this correctly or is it just a bad design I use? (I stripped the code down to the minimum including removing any safety concerns.) class Program { [STAThread] static void Main() { // do stuff here, e.g. open a form new Thread(new ThreadStart(RunStuff); // do more stuff } private void RunStuff() { DoStuff stuff = new DoStuff(); stuff.PerformStuff(); } } class DoStuff : IDisposable { private AxControl activexControl; DoStuff() { activexControl = new AxControl(); activexControl.CreateControl(); // force instance } ~DoStuff() { Dispose(); } public void Dispose() { activexControl.Dispose(); } public void PerformStuff() { // invent perpetuum mobile here, takes time } }

  • Function pointers in Objective-C

    - by Stefan Klumpp
    I have the following scenario: Class_A - method_U - method_V - method_X - method_Y Class_B - method_M - method_N HttpClass - startRequest - didReceiveResponse // is a callback Now I want to realize these three flows (actually there are many more, but these are enough to demonstrate my question): Class_A :: method_X -> HttpClass :: startRequest:params -> ... wait, wait, wait ... -> HttpClass :: didReceiveResponse -> Class_A :: method_Y:result and: Class_A :: method_U -> HttpClass :: startRequest:params -> ... wait, wait, wait ... -> HttpClass :: didReceiveResponse -> Class_A :: method_V:result and the last one: Class_B :: method_M -> HttpClass :: startRequest:params -> ... wait, wait, wait ... -> HttpClass :: didReceiveResponse -> Class_B :: method_N:result Please note, that the methods in Class_A and Class_B have different names and functionality, they just make us of the same HttpClass. My solution now would be to pass a C function pointer to startRequest, store it in the HttpClass and when didReceiveResponse gets called I invoke the function pointer and pass the result (which will always be a JSON Dictionary). Now I'm wondering if there can be any problems using plain C or if there are better solutions doing it in a more Objective-C way. Any ideas?

  • Is VisualAssistX's autorenaming reliable?

    - by Stefan Monov
    I'm using the VS addon called VisualAssistX. Using it for C++ only. In particular i'm using the feature "rename this entity projectwide", mainly for class names and function names. My question is: does this use fuzzy heuristics, or does it actually reliably implement C++ semantics so there's no false negatives/false positives? Has it ever renamed something wrong for you?

  • Objective-C: when does an assigned object get deallocated

    - by Stefan Klumpp
    If I have a instance method and within this method I do something like this: NSString *peopleString = [peopleList componentsJoinedByString: @", "]; ... UILabel *likeLabel = [[UILabel alloc] initWithFrame:CGRectMake(16.0+6.0f, 4.0f, 252.0f, 12.0f)]; [likeLabel setText:peopleString]; [likeLabel setFont:[UIFont fontWithName:@"Arial" size:12]]; [likeRow addSubview:likeLabel]; [likeLabel release]; The componentsJoinedByString doesn't contain a new, copy or alloc, thus I don't have to release it. What I'm wondering though is, when my peopleString gets deallocated. Might it happen to early? Meaning, before I can set the text in my label. Should I better use a [[NSString alloc] initWithString:[peopleList componentsJoinedByString: @", "]]; and release it at the end of this method?

  • Database design: How should I add an information which can apply to several tables

    - by Stefan
    I am constructing a database System using Mysql, this will be an application of about 20 tables. The system contains information on farmers, we work with organic certification and need to record a lot of info for that. In my system, there are related parent-child tables for farmers, producing years and fields/areas - it's a simple representation of the real world in which farmers farm crops on their fields. I now need to add several status flags for each one of these levels: a farmer can be certified, or his field can be, or the specific year can be; each of these flags has several states and can occur a number of times. The obvious solution to this would be to add a child table to every one of these tables, and define the states there. What I wonder if there is an easier way to do this to avoid getting to many tables? Where/how would be best practise to keep that data?

  • How to log C++ exception if running outside debugger, otherwise rethrow

    - by Stefan Monov
    I wanna do something like this: int main() { try { runApp(); } catch(std::exception const& ex) { if(runningInDebugger()) throw; // let the IDE show me what went wrong else displayMsgBox("Something went wrong! " + ex.what()); } } Needs to work at least in VS2008 but the more debuggers it supports, the better. I want it to check for a debugger at runtime. I don't want to do "#ifdef NDEBUG", because I prefer not to do release builds at all (can't be bothered). So what should I use as a "runningInDebugger()" check?

  • When to release a class with delegates

    - by Stefan Mayr
    A quick question to delegates. Lets say, CLASSA has a delegate defined: @protocol MyDelegate -(void) didFinishUploading; @end In CLASSB I create an instance of CLASS A -(void) doPost { CLASSA *uploader = [[CLASSA alloc] init]; uploader.delegate = self; // this means CLASSB has to implement the delegate uploader.post; } and also in CLASSB: -(void)didFinishUploding { } So when do I have to release the uploader? Because when I release it in doPost, it is not valid anymore in didFinishUploading. Thanks
