  • A way to automatically organize #imports in Xcode

    - by Arrel
    I love the "Organize Imports" command in Eclipse to implicitly add and remove classes imported into a source file (as in Java or ActionScript). Is there a command in Xcode to update the #import directives at the top of.m Objective-C files based on the classes referenced within the file?

  • Android Progress Dialog not showing

    - by ilomambo
    This is the handler, in the main Thread, which shows and dismisses a progress dialog. public static final int SHOW = 0; public static final int DISMISS = 1; public Handler pdHandler = new Handler() { @Override public void handleMessage(Message msg) { Log.i(TAG, "+ handleMessage(msg:" + msg + ")"); switch(msg.what) { case SHOW: pd = ProgressDialog.show(LogViewer.this, "", getText(R.string.loading_msg), true); break; case DISMISS: if(pd != null) { pd.dismiss(); pd = null; } break; } } }; The message to show the progress is: pdHandler.sendMessage(pdHandler.obtainMessage(SHOW)); The message to dismiss it is: pdHandler.sendMessage(pdHandler.obtainMessage(DISMISS)); It works well when I call it before I start an AsyncTask, the AsyncTask onPostExecute() dismisses it. But when it runs within a runnable (runOnUiThread), the dialog does not show. Examining the pd variable on the debugger, it shows that is is created, it is running and it is visible, but in practice it is not visible. Any suggestion? UPDATE: I did the obvious test I should have done in the first place. I commented the DISMISS message. And the progress dialog did show up. It appeared too late, after the runnable was finished. I undestand now that the DISMISS message did dismiss the not-yet-visible ProgressDialog, that's why I did not see it. The question becomes now: I need the ProgressDialog to show BEFORE the runnable code is executed. And it is not so straight forward. My call hierarchy is like this: onScrollEventChanged --> runOnUiThread ( --> checkScrollLimits --> if need to scroll show ProgressDialog "Loading" get new data into table dismiss ProgressDIalog ) I tried something like this: onScrollEventChanged --> checkScrollLimits --> if need to scroll show ProgressDialog "Loading" --> runOnUiThread ( get new data into table dismiss ProgressDIalog ) But still the dismiss message got there before the ProgressDialog could show. According to Logcat there is a five second interval between the arrival of the SHOW message and the arrival of the DISMISS message. UPDATE II: I though I will use the isShowing() method of ProgressDIalog pd = ProgressDialog.show(...) while(!pd.isShowing()); But it does not help at all, it returns true even if the dialog is not showing yet.

  • Transaction within IF THEN ELSE doesn't commit

    - by boris callens
    In my TSQL script I have an IF THEN ELSE structure that checks if a column already exists. If not it creates the column and updates it. IF NOT EXISTS( SELECT 1 FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'tableName' AND COLUMN_NAME = 'columnName')) BEGIN BEGIN TRANSACTION ALTER TABLE tableName ADD columnName int NULL COMMIT BEGIN TRANSACTION update tableName set columnName = [something] from [subquery] COMMIT END This doesn't work because the column doesn't exist after the commit. Why doesn't the COMMIT commit?

  • How to obtain the correct physical size of the monitor?

    - by KindDragon
    How can I get the size of the display in centimeters or inches? This code does not always works correctly: HDC hdc = CreateDC(_T("DISPLAY"),dd.DeviceName,NULL,NULL); int width = GetDeviceCaps(hdc, HORZSIZE); int height = GetDeviceCaps(hdc, VERTSIZE); ReleaseDC(0, hdc) Especially for multi-monitor configuration. Update: I need to get the size just for ordinary monitors, which have a constant physical size.

  • Large transactions causing "System.Data.SqlClient.SqlException: Timeout expired" error?

    - by Michael
    My application requires a user to log in and allows them to edit a list of things. However, it seems that if the same user always logs in and out and edits the list, this user will run into a "System.Data.SqlClient.SqlException: Timeout expired." error. I've read comments about increasing the timeout period but I've also read a comment about it possibly caused by uncommitted transactions. And I do have one going in the application. I'll provide the code I'm working with and there is an IF statement in there that I was a little iffy about but it seemed like a reasonable thing to do. I'll just go over what's going on here, there is a list of objects to update or add into the database. New objects created in the application are given an ID of 0 while existing objects have their own ID's generated from the DB. If the user chooses to delete some objects, their IDs are stored in a separate list of Integers. Once the user is ready to save their changes, the two lists are passed into this method. By use of the IF statement, objects with ID of 0 are added (using the Add stored procedure) and those objects with non-zero IDs are updated (using the Update stored procedure). After all this, a FOR loop goes through all the integers in the "removal" list and uses the Delete stored procedure to remove them. A transaction is used for all this. Public Shared Sub UpdateSomethings(ByVal SomethingList As List(Of Something), ByVal RemovalList As List(Of Integer)) Using DBConnection As New SqlConnection(conn) DBConnection.Open() Dim MyTransaction As SqlTransaction MyTransaction = DBConnection.BeginTransaction() Try For Each SomethingItem As Something In SomethingList Using MyCommand As New SqlCommand() MyCommand.Connection = DBConnection If SomethingItem.ID > 0 Then MyCommand.CommandText = "UpdateSomething" Else MyCommand.CommandText = "AddSomething" End If MyCommand.Transaction = MyTransaction MyCommand.CommandType = CommandType.StoredProcedure With MyCommand.Parameters If MyCommand.CommandText = "UpdateSomething" Then .Add("@id", SqlDbType.Int).Value = SomethingItem.ID End If .Add("@stuff", SqlDbType.Varchar).Value = SomethingItem.Stuff End With MyCommand.ExecuteNonQuery() End Using Next For Each ID As Integer In RemovalList Using MyCommand As New SqlCommand("DeleteSomething", DBConnection) MyCommand.Transaction = MyTransaction MyCommand.CommandType = CommandType.StoredProcedure With MyCommand.Parameters .Add("@id", SqlDbType.Int).Value = ID End With MyCommand.ExecuteNonQuery() End Using Next MyTransaction.Commit() Catch ex As Exception MyTransaction.Rollback() 'Exception handling goes here End Try End Using End Sub There are three stored procedures used here as well as some looping so I can see how something can be holding everything up if the list is large enough. Other users can log in to the system at the same time just fine though. I'm using Visual Studio 2008 to debug and am using SQL Server 2000 for the DB.

  • Providing unique layout for specific resolution in Android 2.3.3

    - by user1384991
    I need to use specific xml-layouts based on screen resolution, not size. So, the first design is used for resolution <= 480x800, and the second - for resolution = 480x800. How is it done ? update. Possible solution: Display display = ((WindowManager) getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay(); final int height = display.getHeight(); final int width = display.getWidth();

  • Is is faster to filter and get data or filter then get data ?

    - by remi bourgarel
    Hi I have this kind of request : SELECT myTable.ID, myTable.Adress, -- 20 more columns of all kind of type FROM myTable WHERE EXISTS(SELECT * FROM myLink WHERE myLink.FID = myTable.ID and myLink.FID2 = 666) myLink has a lot of rows. Do you think it's faster to do like this : SELECT myLink.FID INTO @result FROM myLink WHERE myLink.FID2 = 666 UPDATE @result SET Adress = myTable.Adress, -- 20 more columns of all kind of type FROM myTable WHERE myTable.ID = @result.ID

  • PHP ORM's, multiple tables and efficiency

    - by sunwukung
    Let's say I have a data mapper function that aggregates multiple tables and generates an object instance from that data. The mapper has a typical save() method which delegates to update/insert. When the mapper executes save - ideally it isolates object fields that have been modified, thus preventing the code from blanket bombing the database. How would you go about this?

  • How to change file contents in PHP ?

    - by Misha Moroshko
    I save in a file some info about users (like number of times user passed the login page, last visited time, and so on). I want to read this info from the file, and update it (add 1 to the counter, and change the last visited time). My question is: can I do it without opening the file twice ? I open the first time to read the contents, and then open it again to overwrite the contents with the updated ones. Thanks !
