• C++/CLI: CA2123: Requires SecurityCriticalAttribute?

  - by TomTom

  I am a little lost on erros like that: Warning 7 CA2123 : Microsoft.Security : Add the following security attribute to 'RithmicConnector::Connect(String^)' in order to match a LinkDemand on base method 'IConnector::Connect(String^)': 'SecurityCriticalAttribute'. c:\work\nettecture\tradex\source\tradex.connectivity.rithmic\rithmicconnector.cpp 52 Tradex.Connectivity.Rithmic Where do I add the SecurityCriticalAttribute? I tried on the header file - but the error does not disappear. I have one of those pretty much on every exposed method of a (managed C++) interface DLL. And I want CA to run through. How do I fix those? Regards

• Streaming audio to mobile phones, what technology to use ?

  - by Alx

  I'm planning on building an application where audio media is going to be streamed to the mobile phone for the user to listen. The targets are smartphones: iPhone/Blackberry/Android/(J2ME ?). I see that streaming on iPhone has to be done with HTTP Live streaming, but I don't see it supported by other platforms. Should I broadcast the streams via rstp ? http ? Is there any way to use a unified solution for all the different mobile platform ? If anyone already had to go through this, help would be gratly appreciated.

• ADB crashes when device attached with eclipse

  - by user559592

  I am trying to get a development environment setup and having some problems with adb. I have eclipse installed and can create android projects and run/debug them in the emulator. But if I attached my device (HTC Evo) and try running on it, adb crashes. My device shows up so adb sees it. Everything is updated to the latest version. I even went and reinstalled my system so I had a clean start. It would still crash when I connect to the device. I restart adb but it just shuts right back down. Anyone have any suggestions on what I can do to fix this? Running on Windows 7.

• Unable to add Solution to TFS 2010 due to existing (invisible)binding

  - by Refracted Paladin

  I have a smallish utility library I made that I had created in TFS Beta 2 to test out TFS. I now have TFS rc1 installed(and Beta 2 uninstalled) and am trying to add my Solution to TFS. I get an error saying that it is already bound to my old TFS, which was on a different system then this one. Strangely, when I go into Source Control and look at the bindings it says there aren't any. Also, I manually deleted the .vss and .vsc files and it still does it. Ideas? I looked through the numerous other SO topics related to this but unless I missed one none of them are dealing with my issue. Ideas?

• printing long compilation lines with MS NMAKE

  - by Elazar Leibovich

  I have a legacy MS NMAKE Makefile I need to fix a few bugs in. There are some very long command lines I wish to debug that are being executed using the NMAKE trick of "inline files": dep: cmd @<<tmpfilename cmd_args.. << When changing the line to dep: echo cmd @<<tmpfilename cmd_args.. << NMAKE complains that the line is too long. Is there any other trick I can apply in order to view the command line NMAKE is actually executing?

• Compiler doesn't find methods from base class

  - by Paul

  I am having a problem with my virtual methods in a derived class. Here are my (simplified) C++ classes. class Base virtual method accept( MyVisitor1* v ) { /*implementation is here*/ }; virtual method accept( MyVisitor2* v ) { /*implementation is here*/ }; virtual method accept( MyVisitor3* v ) { /*implementation is here*/ }; class DerivedClass virtual method accept( MyVisitor2* v ) { /*implementation is here*/ }; The following use causes VS 2005 to give: "error C2664: 'DerivedClass::accept' : cannot convert parameter 1 from 'Visitor1*' to 'Visitor2 *'". DerivedClass c; MyVisitor1 v1; c.accept(v1); I was expecting the compiler to find and call Base::accept(MyVisitor1) for my DerivedClass as well. Obviously this is not working, but I don't understand why. Any ideas? Thanks, Paul

• Keeping the application state - deploy/install apk

  - by Buffalo

  I'm trying to have my application minimized when paused and then when it's resumed, it should be restored to its previous state, not recreated. This works perfectly when deploying the application on a device/emulator from Eclipse. The problem occurs when I get the apk (either from bin\ or from Project - Android tools - Export signed application package) and install it on a device with a file browser (Astro): the application is destroyed when paused and then recreated. I can call moveTaskToBack(true); in my activity, yet it will still be recreated when launching it. All the discussions around this are based on achieving the opposite: closing the application when minimizing it. Is there any way of achieving what I want?

  I have a complex inheritance structure in my data model. A majority of classes in my model (which is designed in VS 2010 with a DB generated by it after) are derived from 3 basic classes. And only these 3 classes can be found among the context members. How do I use all the derived classes at all?

• jQuery "growl-like" effect in VB.net

  - by StealthRT

  Hey all, i have made a simple form that mimiks the jQuery "GROWL" effect seen here http://www.sandbox.timbenniks.com/projects/jquery-notice/ However, i have ran into a problem. If i have more than one call to the form to display a "Growl" then it just refreshes the same form with whatever call i send it. In other words, i can only display one form at a time instead of having one drop down and a new one appear above it. Here is my simple form code for the "GROWL" form: Public Class msgWindow Public howLong As Integer Public theType As String Private loading As Boolean Protected Overrides Sub OnPaint(ByVal pe As System.Windows.Forms.PaintEventArgs) Dim pn As New Pen(Color.DarkGreen) If theType = "OK" Then pn.Color = Color.DarkGreen ElseIf theType = "ERR" Then pn.Color = Color.DarkRed Else pn.Color = Color.DarkOrange End If pn.Width = 2 pe.Graphics.DrawRectangle(pn, 0, 0, Me.Width, Me.Height) pn = Nothing End Sub Public Sub showMessageBox(ByVal typeOfBox As String, ByVal theMessage As String) Me.Opacity = 0 Me.Show() Me.SetDesktopLocation(My.Computer.Screen.WorkingArea.Width - 350, 15) Me.loading = True theType = typeOfBox lblSaying.Text = theMessage If typeOfBox = "OK" Then Me.BackColor = Color.FromArgb(192, 255, 192) ElseIf typeOfBox = "ERR" Then Me.BackColor = Color.FromArgb(255, 192, 192) Else Me.BackColor = Color.FromArgb(255, 255, 192) End If If Len(theMessage) <= 30 Then howLong = 4000 ElseIf Len(theMessage) >= 31 And Len(theMessage) <= 80 Then howLong = 7000 ElseIf Len(theMessage) >= 81 And Len(theMessage) <= 100 Then howLong = 12000 Else howLong = 17000 End If Me.opacityTimer.Start() End Sub Private Sub opacityTimer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles opacityTimer.Tick If Me.loading Then Me.Opacity += 0.07 If Me.Opacity >= 0.8 Then Me.opacityTimer.Stop() Me.opacityTimer.Dispose() Pause(howLong) Me.loading = False Me.opacityTimer.Start() End If Else Me.Opacity -= 0.08 If Me.Opacity <= 0 Then Me.opacityTimer.Stop() Me.Close() End If End If End Sub Public Sub Pause(ByVal Milliseconds As Integer) Dim dTimer As Date dTimer = Now.AddMilliseconds(Milliseconds) Do While dTimer > Now Application.DoEvents() Loop End Sub End Class I call the form by this simple call: Call msgWindow.showMessageBox("OK", "Finished searching images.") Does anyone know a way where i can have the same setup but would allow me to add any number of forms without refreshing the same form over and over again? Like always, any help would be great! :) David

• adapting combination code for larger list

• DebuggerDisplay attribute does not work as expected!

  - by mark

  Dear ladies and sirs. I know that this attribute should work in C# and yet, in my case it does not. I have a class with a lazy property Children. Accessing this property may have a side effect of roundtripping to the server. So, naturally, I do not want this to happen when I just watch it in the debugger watch window. Omitting all the irrelevant details the source looks pretty ordinary: [DebuggerDisplay("(Frozen) {m_children}")] public IList<IEntityBase> Children { get { if (m_children == null) { m_children = FetchChildrenFromDB(this); } return m_children; } } And yet, when I watch the object and expand this in the watch window I do not see (Frozen) in the display, meaning the debugger simply ignores the attribute. Provided the image link is still valid it should be visible below: http://i28.tinypic.com/2zxo9s5.jpg The attribute is really there, according to Reflector. I use VS2008. Any ideas?

• Is java.util.Scanner that slow?

  - by Cristian Vrabie

  Hi guys, In a Android application I want to use Scanner class to read a list of floats from a text file (it's a list of vertex coordinates for OpenGL). Exact code is: Scanner in = new Scanner(new BufferedInputStream(getAssets().open("vertexes.off"))); final float[] vertexes = new float[nrVertexes]; for(int i=0;i<nrVertexFloats;i++){ vertexes[i] = in.nextFloat(); } It seems however that this is incredibly slow (it took 30 minutes to read 10,000 floats!) - as tested on the 2.1 emulator. What's going on? I don't remember Scanner to be that slow when I used it on the PC (truth be told I never read more than 100 values before). Or is it something else, like reading from an asset input stream? Thanks for the help!

• Effective Method to Manage and Search Through 100,000+ Objects Instantly? (C#)

  - by Kirk

  I'm writing a media player for enthusiasts with large collections (over 100,000 tracks) and one of my main goals is speed in search. I would like to allow the user to perform a Google-esque search of their entire music collection based on these factors: Song Path and File Name Items in ID3 Tag (Title, Artist, Album, etc.) Lyrics What is the best way for me to store this data and search through it? Currently I am storing each track in an object and iterating over an array of these objects checking each of their variables for string matches based on given search text. I've run into problems though where my search is not effective because it is always a phrase search and I'm not sure how to make it more fuzzy. Would an internal DB like SQLlite be faster than this? Any ideas on how I should structure this system? I also need playlist persistence, so that when they close the app and open the app their same playlist loads immediately. How should I store the playlist information so it can load quickly when the application starts? Currently I am JSON encoding the entire playlist, storing it in a text file, and reading it into the ListView at runtime, but it is getting sluggish over 20,000 tracks. Thanks!

• Best approach to show big amount of "grid" data

  - by Jorge Ramírez

  Hello all. I am building an application for Android (1.5) that, after quering a webservice, shows to the user a big amount of data that should be displayed in a "grid" or "table" style. I must show a result of about 7 columns and 50 rows (for example a customer list with names, adresses, telephone number, sales amount last year and so). Obviously, the 7 columns will not fix in the screen and I would like the user would be able to scroll up/down and LEFT/RIGHT (important because of the number of columns) to explore the grid results. cell selection level is NOT necessary, as much I would need row selection level. What is the best approach to get this interface element? Listview / GridView / TableLayout? Thanks

• Implement subitem in SQLite

  - by Mohit Deshpande

  How could I implement a sub item where the item would have a parent to that of the same item. For example, I have a database that holds tasks/todos. Each todo has a title(TEXT), completed(INTEGER [1 if true, 0 if false]), and due date(TEXT) column. I would like to add functionality to have subtasks, where a task could possibly have a parent task. How would I implement this in SQLite for Android? NOT IN SQL! So no foreign keys (triggers are allow, though)! Could I just have a separate table (subtask) and have a foreign key trigger to link subtask(INTEGER parent) to task(INTEGER PRIMARY KEY AUTOINCREMENT _id)? Or should I add a column to my original task table(INTEGER parent)? How could I implement this?

Thanks!

Have anybody know how I can do this? Thanks!
