Tools for managing code deployment/versioning for IIS / Windows enviroments

- by RizwanK

I've got a strong background in Linux and OSX, and just left a job where I was architecting systems based on those platforms. Now I've got a Windows Server running IIS that has a number of different websites that it hosts. Most of them are just a bunch of HTML, JS and Images, with some ASP for some customer tools. (Each website has a different set of customer tools, or they are the same tools, but with minor code changes between them.) I'm also adding a develop web server with the same code, but the 'bleeding edge' stuff. I need an effective way of managing changes and updates to the overall codebase (henceforth referring to both the images and the html and the asp, for all the sites). When a dev (or webmaster) checks in changes, I want it to show up automatically on the developer server, but should be manually pushed out to the live server. I'd be tempted to just make the websites SVN repositories, but I'd be concerned about the overhead of having the webdeveloper having to log into the server and trigger an SVN update via commandline/tortise (and heaven forbid, manage tags). Ideally I'd also manage IIS profile settings between the systems, but the major need is to be able to manage the process, and expose it to our ASP developer, and our webmaster, both of which are used to just FTPing up the files to the live site. So, any recommendations on tools (beyond some SVN hacking with BAT files + teaching the webmaster how to log into the server and do updates) or workflows that would help this out? I even considered an RPM type package (or some Windows equivalent, of course) to manage the live server, but that seems like a bit too much overhead. Thanks.

JQuery: Combine multiple pages into one

- by k_wave

I am developing an application by using phonegap and jQuery Mobile. Phonegap recommends a single document structure. As 5 divs or more in a document are pretty unclear, I'm trying to split up my pages (the div's) into multiple documents. As soon as phonegap loads the app, I want to insert these documents into the index.html. function loadPage(external_document) { var docname=external_document+".html"; $.get(docname, function(data) { console.log(docname+" loading"); $("body").append($(data).find("body")); $("head").append($(data).find("head")); console.log(docname+" loaded"); }); } document.addEventListener("deviceready", function(){ loadPage("DialogCredentials"); }, false); DialogCredentials.html <html> <head> <script type="text/javascript" src="js/DialogCredentials.js"></script> </head> <body> <div data-role="page" id="dlg_credentials"> <div data-role="header"><h1>Login</h1></div> <div data-role="content"> ... </div> </div> </body> </html> As soon as the loadPage gets executed there should be a <div id="dlg_credentials"… and the corresponding javascript tag in the dom of my main document. But it isn't. There are no errors shown in the web inspector. So what am I doing wrong here?

I am using the latest phonegap/cordova version 2.1. and my log in Eclipse logcat get polluted with code when i do var allItems = Item.all(); allItems.list(null, function (results) { results.forEach(function (r) { console.log(r.id+ " " + r.lat + " " + r.long + " " + r.state); }); }); I get a output like (for 100s of lines) 10-29 10:56:13.270: I/Web Console(5961): } function (value) { 10-29 10:56:13.270: I/Web Console(5961): if (value === undefined) { 10-29 10:56:13.270: I/Web Console(5961): return getterCallback(); 10-29 10:56:13.270: I/Web Console(5961): } else { 10-29 10:56:13.270: I/Web Console(5961): setterCallback(value); 10-29 10:56:13.270: I/Web Console(5961): return scope; 10-29 10:56:13.270: I/Web Console(5961): } 10-29 10:56:13.270: I/Web Console(5961): } function (value) { 10-29 10:56:13.270: I/Web Console(5961): if (value === undefined) { 10-29 10:56:13.270: I/Web Console(5961): return getterCallback(); 10-29 10:56:13.270: I/Web Console(5961): } else { 10-29 10:56:13.270: I/Web Console(5961): setterCallback(value); 10-29 10:56:13.270: I/Web Console(5961): return scope; 10-29 10:56:13.270: I/Web Console(5961): } 10-29 10:56:13.270: I/Web Console(5961): } function (value) { 10-29 10:56:13.270: I/Web Console(5961): if (value === undefined) { 10-29 10:56:13.270: I/Web Console(5961): return getterCallback(); 10-29 10:56:13.270: I/Web Console(5961): } else { 10-29 10:56:13.270: I/Web Console(5961): setterCallback(value); 10-29 10:56:13.270: I/Web Console(5961): return scope; 10-29 10:56:13.270: I/Web Console(5961): } 10-29 10:56:13.270: I/Web Console(5961): } at :1149822901

Array, change color, as3

- by pixelGreaser

Hi Thanks for the help Yesterday, but I have on more question. How can I change color of text on certain words? My animation plays the text animation of THIS SALE IS RED HOT!!! I want RED HOT it to be red. It seems the array can be indexed in such a way to switch the color from Blue to Red. MY BANNER ADD var myArray:Array = ["THIS","SALE","IS","RED HOT!!!",]; var tm:Timer = new Timer(500); tm.addEventListener(TimerEvent.TIMER, countdown); function countdown(event:TimerEvent) { tx.text = myArray[(tm.currentCount-1)%myArray.length]; } tm.start(); tx.textColor = 0x0000FF; Cont...PSEUDO CODE //var myArray:Array = ["This","Sale","is","RED HOT!!!",]; var spliceRedhot = myArray.splice(-1); //trace(myArray[2]); trace(spliceRedhot); function mySplice(e:Event):void{ if (spliceRedhot = 4){ //Make RED HOT!!! red tx.textColor = 0xFF0000; } else{ //Text is Blue again tx.textColor = 0x0000FF; } }

C++ MFC server app with sockets crashes and I cannot find the fault, help!

- by usermeister

My program has one dialog and two sockets. Both sockets are derived from CAsyncSocket, one is for listening, other is for receiving data from client. My program crashes when client tries to connect to server application and server needs to initialize receiving socket. This is my MFC dialog class. class CFileTransferServerDlg : public CDialog { ... ListeningSocket ListenSock; ReceivingSocket* RecvSock; void OnAccept(); // called when ListenSock gets connection attempt ... }; This is my derived socket class for receiving data that calls parent dialogs method when event is signaled. class ReceivingSocket : public CAsyncSocket { CFileTransferServerDlg* m_pDlg; // for accessing parent dialogs controls virtual void OnReceive(int nErrorCode); } ReceivingSocket::ReceivingSocket() { } This is dialogs function that handles incoming connection attempt when listening socket gets event notification. This is where the crash happens. void CFileTransferServerDlg::OnAccept() { RecvSock = new ReceivingSocket; /* CRASH */ } OR void CFileTransferServerDlg::OnAccept() { ReceivingSocket* tmpSock = new ReceivingSocket; tmpSock->SetParentDlg(this); CString message; if( ListenSock.Accept(*tmpSock) ) /* CRASH */ { message.LoadStringW(IDS_CLIENT_CONNECTED); m_txtStatus.SetWindowTextW(message); RecvSock = tmpSock; } } My program crashes when I try to create a socket for receiving file sent from client application. OnAccept starts when Listening socket signals incoming connection attempt, but my application then crashes. I've tried running it on another computer and connection attempt was succesful. What could be wrong? Error in debug mode: Unhandled exception at 0x009c30e1 in FileTransferServer.exe: 0xC0000005: Access violation reading location 0xccccce58.

Passing Object From Controller to JavaScript JQuery

- by TMan

This is driving me crazy. All I'm trying to do is to pass in a Id to a ActionMethod which is working and have an Object be returned to the javascript. Then in javascript, I want to be able to say something like..Objec.Property, ie/ Student.Name, or Student.GPA. Any help is appreciated. I tried json but couldn't get that to work either. ActionResult: [AcceptVerbs(HttpVerbs.Get)] public Epic GetEpicPropertyDetails(int id) { var Epictemplist = epicRepository.Select().Where(x => x.Id.Equals(id)); return Epictemplist.SingleOrDefault(); } javascript: <script type="text/javascript"> $(document).ready(function () { $(".ListBoxClass").click(function (event) { var selectedid = $(this).find("option:selected").val(); event.preventDefault(); $.get("/Estimate/GetEpicPropertyDetails", { id: selectedid }, function (result) { $(".TimeClass").val(result); }); }); }); </script> result.Name is obviously wrong I just dont know how to call this the right way.

Exceptions over remote methods

- by Andrei Vajna II

What are the best practices for exceptions over remote methods? I'm sure that you need to handle all exceptions at the level of a remote method implementation, because you need to log it on the server side. But what should you do afterwards? Should you wrap the exception in a RemoteException (java) and throw it to the client? This would mean that the client would have to import all exceptions that could be thrown. Would it be better to throw a new custom exception with fewer details? Because the client won't need to know all the details of what went wrong. What should you log on the client? I've even heard of using return codes(for efficiency maybe?) to tell the caller about what happened. The important thing to keep in mind, is that the client must be informed of what went wrong. A generic answer of "Something failed" or no notification at all is unacceptable. And what about runtime (unchecked) exceptions?

How to get a checkout-able revision info from subversion?

- by zhongshu

I want to check a svn url and to get the latest revision, then checkout it, I don't want to use HEAD because I will compare the latest revision to others. so I use "svn info" to get the "Last Changed Rev" for the url like this: D:\Project>svn info svn://.../branches/.../path Path: ... URL: svn://.../branches/.../path Repository Root: svn://yt-file-srv/ Repository UUID: 9ed5ffd7-7585-a14e-96b2-4aab7121bb21 Revision: 2400 Node Kind: directory Last Changed Author: xxx Last Changed Rev: 2396 Last Changed Date: 2010-03-12 09:31:52 +0800 but, I found the 2396 revision is not checkout-able, because this path is in a branch copied from trunk, and the 2396 is the revision modified in the trunk. so when I use svn checkout -r 2396, I will get a workcopy for the path in the trunk, then I can not do checkin for the branch. D:\Project>svn checkout svn://.../branches/.../path -r 2396 workcopy ..... ..... D:\Project>svn info workcopy Path: workcopy URL: svn://.../trunk/.../path Repository Root: svn://yt-file-srv/ Repository UUID: 9ed5ffd7-7585-a14e-96b2-4aab7121bb21 Revision: 2396 Node Kind: directory Schedule: normal Last Changed Author: xxx Last Changed Rev: 2396 Last Changed Date: 2010-03-12 09:31:52 +0800 So, my question is how to get a checkout-able revision for the branch path, for this example, I want to get 2397 (because 2397 is the revision which copy occur). And I know "svn log" can get the info, but "svn log" output maybe very long and parse it will be difficult than "svn info". I just want know which revision is the latest checkout-able revision for the path.

Concurrent connections in C# socket

- by Chu Mai

There are three apps run at the same time, 2 clients and 1 server. The whole system should function as following: The client sends an serialized object to server then server receives that object as a stream, finally the another client get that stream from server and deserialize it. This is the sender: TcpClient tcpClient = new TcpClient(); tcpClient.Connect("127.0.0.1", 8888); Stream stream = tcpClient.GetStream(); BinaryFormatter binaryFormatter = new BinaryFormatter(); binaryFormatter.Serialize(stream, event); // Event is the sending object tcpClient.Close(); Server code: TcpListener listener = new TcpListener(IPAddress.Parse("127.0.0.1"), 8888); listener.Start(); Console.WriteLine("Server is running at localhost port 8888 "); while (true) { Socket socket = listener.AcceptSocket(); try { Stream stream = new NetworkStream(socket); // Typically there should be something to write the stream // But I don't knwo exactly what should the stream write } catch (Exception e) { Console.WriteLine("Exception: " + e.Message); Console.WriteLine("Disconnected: {0}", socket.RemoteEndPoint); } } The receiver: TcpClient client = new TcpClient(); // Connect the client to the localhost with port 8888 client.Connect("127.0.0.1", 8888); Stream stream = client.GetStream(); Console.WriteLine(stream); when I run only the sender and server, and check the server, server receives correctly the data. The problem is when I run the receiver, everything is just disconnected. So where is my problem ? Could anyone point me out ? Thanks

How to understand "if ( obj.length === +obj.length )" Javascript condition statement?

- by humanityANDpeace

I have run across a condition statement which I have some difficulties to understand. It looks like (please note the +-sign on the right-hand-side) this: obj.length === +obj.length. Can this condition and its purpose/syntax be explained? Looking at the statement (without knowing it) provokes the impression that it is a dirty hack of some sort, but I am almost certain that underscore.js is rather a well designed library, so there must be a better explanation. Background I found this statement used in some functions of the underscore.js library (underscore.js annotated source). My guesswork is that this condition statement is somehow related to testing for a variable obj to be of Array type? (but I am totally unsure). I have tried to test this using this code. var myArray = [1,2,3]; testResult1 = myArray.length === +myArray.length; console.log( testResult1 ); //prints true var myObject = { foo : "somestring", bar : 123 }; testResult2 = myObject.length === +myObject.length; console.log( testResult2 ); //prints false

How should I lock the table in this VB6 / Access application?

- by Brian Hooper

I'm working on a VB6 application using an Access database. The application writes messages to a log table from time to time. Several instances of the application may be running simultaneously and to distinguish them they each have their own run number. The run number is deduced from the log table thus... Set record_set = New ADODB.Recordset query_string = "SELECT MAX(RUN_NUMBER) + 1 AS NEW_RUN_NUMBER FROM ERROR_LOG" record_set.CursorLocation = adUseClient record_set.Open query_string, database_connection, adOpenStatic, , adCmdText record_set.MoveLast If IsNull(record_set.Fields("NEW_RUN_NUMBER")) Then run_number = 0 Else run_number = record_set.Fields("NEW_RUN_NUMBER") End If command_string = "INSERT INTO ERROR_LOG (RUN_NUMBER, SEVERITY, MESSAGE) " & _ " VALUES (" & Str$(run_number) & ", " & _ " " & Str$(SEVERITY_INFORMATION) & ", " & _ " 'Run Started'); " database_connection.Execute command_string Obviously there is a small gap between the calculation of the run number and the appearance of the new row in the database, and to prevent another instance getting access between the two operations I'd like to lock the table; something along the lines of SET TRANSACTION READ WRITE RESERVING ERROR_LOG FOR PROTECTED WRITE; How should I go about doing this? Would locking the recordset do any good (the row in the record set doesn't match any particular row in the database)?

Return a Const Char* by reading an @property NSString in separate class

- by Andrew

I'm probably being an idiot here, but I cannot for the life of me find the answer that I'm looking for. I have an array of CalEvents returned from a CalendarStore query, and for other reasons I am finding the first location of any upcoming event for today that is not an all-day or multi-day event. +(const char*) suggestFirstiCalLocation{ CalCalendarStore *store = [CalCalendarStore defaultCalendarStore]; NSPredicate *allEventsPredicate = [CalCalendarStore eventPredicateWithStartDate:[NSDate date] endDate:[[NSDate date] initWithTimeIntervalSinceNow:3600] calendars:[store calendars]]; NSArray *currentEventCalendarArray = [store eventsWithPredicate:allEventsPredicate]; for (int i = 0; i< [currentEventCalendarArray count]; i++){ if (![[currentEventCalendarArray objectAtIndex:i] isAllDay]){ //Now that other events are cleared, check for multi-day NSDate *startOnDate = [[currentEventCalendarArray objectAtIndex:i] startDate]; NSDate *endOnDate = [[currentEventCalendarArray objectAtIndex:i] endDate]; if ([endOnDate timeIntervalSinceDate:startOnDate ] < 86400.0){ NSString * iCalLocation = [[currentEventCalendarArray objectAtIndex:i] location]; return [iCalLocation UTF8String]; } } } return ""; } For other reasons, I am returning a const char with the value of the location that is found. However, I cannot seem to return "iCalLocation" at all. The compiler fails on the line where I am initializing the "iCalLocation" variable: "Cannot convert to pointer type" Being frank: I am new to Objective-C, and I am still trying to figure points, properties, and such out.

Write to PDF using PHP from android device

I am trying to write to a pdf file on php server. I have sent variables to the server, create the pdf document, then have my phone download the document to view on device. The variables seem not to write on the php file. I have my code below public void postData() { try { Calculate calc = new Calculate(); HttpClient mClient = new DefaultHttpClient(); StringBuilder sb=new StringBuilder("myurl.com/pdf.php"); HttpPost mpost = new HttpPost(sb.toString()); String value = "1234"; List nameValuepairs = new ArrayList(1); nameValuepairs.add(new BasicNameValuePair("id",value)); mpost.setEntity(new UrlEncodedFormEntity(nameValuepairs)); } catch (UnsupportedEncodingException e) { Log.w(" error ", e.toString()); } catch (Exception e) { Log.w(" error ", e.toString()); } } And my php code to write the variable "value" onto the pdf document: //code to reverse the string if($_POST[] != null) { $reversed = strrev($_POST["value"]); $this->SetFont('Arial','u',50); $this->Text(52,68,$reversed); } I am just trying to write the variable in a random spot, but the variable the if statement is always null and I do not know why. Thanks. Sorry if it is a little sloppy.

Append to the end of a Char array in C++

- by Taylor Huston

Is there a command that can append one array of char onto another? Something that would theoretically work like this: //array1 has already been set to "The dog jumps " //array2 has already been set to "over the log" append(array2,array1); cout << array1; //would output "The dog jumps over the log"; This is a pretty easy function to make I would think, I am just surprised there isn't a built in command for it. *Edit I should have been more clear, I didn't mean changing the size of the array. If array1 was set to 50 characters, but was only using 10 of them, you would still have 40 characters to work with. I was thinking an automatic command that would essentially do: //assuming array1 has 10 characters but was declared with 25 and array2 has 5 characters int i=10; int z=0; do{ array1[i] = array2[z]; ++i; ++z; }while(array[z] != '\0'); I am pretty sure that syntax would work, or something similar.

tracking the position of dragview

- by user262325

Hello everyone I put a dragview on an UIView, I hope when I drag the dragview, its superview (UIView) tracks the position of the dragview and moves itself to the position where to keep dragview at the original position on the UIView. The codes show below: #import <UIKit/UIKit.h> @interface DragView : UIImageView { CGPoint startLocation; } @end #import "DragView.h" @implementation DragView - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { // Initialization code } return self; } - (void)drawRect:(CGRect)rect { // Drawing code } -(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent*)event { CGPoint pt=[[touches anyObject] locationInView:self]; startLocation=pt; [[self superview] bringSubviewToFront:self]; } -(void) touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { CGPoint pt=[[touches anyObject] locationInView:self]; CGRect frame=[self frame]; frame.origin.x+=pt.x-startLocation.x; frame.origin.y+=pt.y-startLocation.y; CGRect frame1=[[self superview] frame];//superview of the dragview frame1.origin.x+=frame.origin.x; //tracks the postion of dragview frame1.origin.y+=frame.origin.y; [[self superview] setFrame: frame1 ]; //move to new position [self setFrame:frame]; } my problem is that the UIView moved but lagged to the movement of the drageview(RED BLOCK).

Prompting for authentication from a wxPython program and passing it along to IIS?

- by MetaHyperBolic

I have a client (written in Python, with a wxPython front end in dead-simple wizard style) which communicates a website running IIS. A python script receives requests and does the usual client-server dance. I would have written this as a browser application, but for the requirement that certain things happen on the local PC that the web can't help with (file manipulation, interfacing with certain USB hardware, etc.) Right now, I am simply using the logon credentials, compounded as a string from os.environ['USERDOMAIN'] and os.environ['USERNAME'], to pass along to the server, which connects to Active Directory and enumerates the members of the group, looking for those logon credentials. It's an ugly hack, but it works. Obviously, I could make people log out of the generic helper accounts and log back into Windows using specific accounts. However, I wondered how feasible it would be to provide some kind of logon prompt wherein the user can type in a name and password, then some kind of authorization token could be passed on to IIS. This seems like something I would not want to do myself, given that amateurs almost always make huge security mistakes. Now you can see why I am wishing this was purely web-based. What's a good way to handle this?

How to send java.util.logging to log4j?

- by matt b

I have an existing application which does all of its logging against log4j. We use a number of other libraries that either also use log4j, or log against Commons Logging, which ends up using log4j under the covers in our environment. One of our dependencies even logs against slf4j, which also works fine since it eventually delegates to log4j as well. Now, I'd like to add ehcache to this application for some caching needs. Previous versions of ehcache used commons-logging, which would have worked perfectly in this scenario, but as of version 1.6-beta1 they have removed the dependency on commons-logging and replaced it with java.util.logging instead. Not really being familiar with the built-in JDK logging available with java.util.logging, is there an easy way to have any log messages sent to JUL logged against log4j, so I can use my existing configuration and set up for any logging coming from ehcache? Looking at the javadocs for JUL, it looks like I could set up a bunch of environment variables to change which LogManager implementation is used, and perhaps use that to wrap log4j Loggers in the JUL Logger class. Is this the correct approach? Kind of ironic that a library's use of built-in JDK logging would cause such a headache when (most of) the rest of the world is using 3rd party libraries instead.

Capture data from jQuery Mobile GUI / form elements like sliders, or the flip switch/toggle, and store in a var?

I have this code, which executes without error, it shows "** slider change **" in the debug console every time the slider changes. But I cannot figure out how to capture the value of the slider so I can store it in a var. Can you help, I'm hoping it's a simple thing. $( '#page4_Options' ).live( 'pageinit', function(event){ var slideTime = userOptions.getSlideTime() / 1000; // userOptions is my Object to get/set params from localStorage. $("input[id='slider']").val(slideTime).slider("refresh"); // set default slide time when page init's. console.log("userOptions.getSlideTime()", userOptions.getSlideTime() ); $( "#slider" ).bind( "slidestop", function(event, ui) { console.log("** slider change **"); // How do I capture the new slider value into a var? }); }); Here's the HTML with the slider, it's in a tag: <div data-role="fieldcontain"> <label for="slider">Slide Duration (seconds):</label> <input type="range" name="slider" id="slider" value="2" min="0" max="60" /> </div>

Can this line of code really throw an IndexOutOfRange exception?

- by Jonathan M

I am getting an IndexOutOfRange exception on the following line of code: var searchLastCriteria = (SearchCriteria)Session.GetSafely(WebConstants.KeyNames.SEARCH_LAST_CRITERIA); I'll explain the above here: SearchCriteria is an Enum with only two values Session is the HttpSessionState GetSafely is an extension method that looks like this: public static object GetSafely(this HttpSessionState source, string key) { try { return source[key]; } catch (Exception exc) { log.Info(exc); return null; } } WebConstants.KeyNames.SEARCH_LAST_CRITERIA is simply a constant I've tried everything to replicate this error, but I cannot reproduce it. I am beginning to think the stack trace is wrong. I thought perhaps the exception was actually coming from the GetSafely call, but it is swallowing the exceptions, so that can't be the case, and even if it was, it should show up in the stack trace. Is there anything in the line of code above that could possible throw an IndexOutOfRange exception? I know the line will throw an NullReferenceException if GetSafely returns null, and it will also throw an InvalidCastException if it returns anything that cannot be cast to SearchCriteria, but an IndexOutOfRange exception? I'm scratching my head here. Here is the stack trace: $LOG--> 2010-06-11 07:01:33,814 [ERROR] SERVERA (14) Web.Global - Index was outside the bounds of the array. System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.IndexOutOfRangeException: Index was outside the bounds of the array. at IterateSearchResult(Boolean next) in C:\Projects\Web\UserControls\AccountHeader.ascx.cs:line 242 at nextAccountLink_Click(Object sender, EventArgs e) in C:\Projects\Web\UserControls\AccountHeader.ascx.cs:line 232

JavaScript: Replacement for XMLSerializer.seralizeToString()?

- by NRaf

I'm developing a website using the Seam framework and the RichFaces AJAX library (these isn't really all that important to the problem at hand - just some background). I seem to have uncovered a bug, however, in RichFaces which, in certain instances, will cause AJAX-based updating to fail in IE8 (see here for more info: http://community.jboss.org/message/585737). The following is the code where the exception is occurring: var anchor = oldnode.parentNode; if(!window.opera && !A4J.AJAX.isWebkitBreakingAmps() && oldnode.outerHTML && !oldnode.tagName.match( /(tbody|thead|tfoot|tr|th|td)/i ) ){ LOG.debug("Replace content of node by outerHTML()"); if (!Sarissa._SARISSA_IS_IE || oldnode.tagName.toLowerCase()!="table") { try { oldnode.innerHTML = ""; } catch(e){ LOG.error("Error to clear node content by innerHTML "+e.message); Sarissa.clearChildNodes(oldnode); } } oldnode.outerHTML = new XMLSerializer().serializeToString(newnode); } The last line (the one with XMLSerializer) is where the exception is occurring in IE. I was wondering if anyone knows of any replacement method / library / etc I could use there (only on IE is fine). Thanks.

WinForms: How to determine if window is no longer active (no child window has focus)?

- by Marek

My application uses multiple windows I want to hide one specific window in case the application loses focus (when the Active Window is not the application window) source I am handling the Deactivate event of my main form. private void MainForm_Deactivate(object sender, EventArgs e) { Console.WriteLine("deactivate"); if (GetActiveWindow() == this.Handle) { Console.WriteLine("isactive=true"); } else { Console.WriteLine("isactive=false"); } } [DllImport("user32.dll")] static extern IntPtr GetActiveWindow(); The output is always deactivate isactive=true I have observed the same behavior if a new window within my application receives focus and also if I click into a different application. I would expect GetActiveWindow to return the handle of the new active window when called from the Deactivate handler. Instead it always returns the handle of my application window. How is this possible? Is the Deactivate event handled "too soon"? (while the main form is still active?). How can I detect that my application has lost focus (my application window is not the active window) and another application gained it without running GetActiveWindow on a timer?

OnClickListener on Tabs not working

- by Aracos

Greetings, I am trying to get the Click - event when clicking on the currently selected tab of my TabActivity. The onTabChangedHandler is only called whenever the tab is changed, not if the currently active Tab is clicked. The debugger tells me i have the onClickListener Registered for the TabWidget within my TabHost. Am i registering for the wrong View? Also, I am unable to create a Context Menu for the Tabs, only for its content, is this problem related? public class TestDroidViewTab extends TabActivity implements TabContentFactory , OnTabChangeListener, OnClickListener { private static final String LOG_KEY = "TEST"; ListView listView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); final TabHost tabHost = getTabHost(); TabHost.TabSpec ts = tabHost.newTabSpec("ID_1"); ts.setIndicator("1"); ts.setContent(this); tabHost.addTab(ts); ts = tabHost.newTabSpec("ID_2"); ts.setIndicator("2"); ts.setContent(this); tabHost.addTab(ts); ts = tabHost.newTabSpec("ID_3"); ts.setIndicator("3"); ts.setContent(this); tabHost.addTab(ts); tabHost.setOnClickListener(this); tabHost.setOnTabChangedListener(this); } public void onClick(View v) { Log.d(LOG_KEY, "OnClick"); } public void onTabChanged(String tabId) { Log.d(LOG_KEY, "OnTabChanged"); }
