# Call this function to get back a list of the images in a given directory. # This makes the assumption that there are no subdirectories. It would be # easy to support that, though. # # Pass in the path to the directory that contains the images. sub getimages{ my($path) = @_; my(@images); print STDERR "Finding images in $path\n"; find(sub{ # Modify the next line to support file formats other than JPEG # if needed if($File::Find::name =~ /\/([^\/]*\.jpg)$/i){ push(@images, $1); } }, $path); return @images; } As discussed in its opening comment, the previous function gets a list of images from a directory. It s important to note that this includes all images in subdirectories as well. The follow option on the File::Find invocation allows Perl to follow symbolic links. # This function is similar to the above but returns a list of the # directories containing at least one image. # # Pass in the path to the parent directory sub getdirectories{ my($path) = @_; my(%directories); find({ wanted=>sub{ # Again, this needs to be tweaked if other image formats are # to be supported if($File::Find::name =~ /\/([^\/]*\.jpg)$/i){ # This is a horrible, horrible hack $directories{$File::Find::dir} = "yes"; } }, follow=>1 }, $path); return keys %directories; } qr code scanner for java free download How to Create a QR Code Reader for Your Mobile Website - SitePoint

2 Oct 2016 ... Curiously your code works for me, but I had to remove the follow hint. tmpHintsMap.put(DecodeHintType.PURE_BARCODE, Boolean.FALSE);. When my image ... In this recipe, I created an inline table UDF to retrieve employee address data based on the @EmployeeID value passed. The UDF started off just like a scalar UDF, only the RETURNS command uses a TABLE data type (which is what distinguishes it from a scalar UDF): CREATE FUNCTION dbo.udf_ReturnEmployeeAddress ( @EmployeeID int) RETURNS TABLE AS After the AS keyword, the RETURN statement is issued with a single SELECT statement in parentheses: RETURN ( SELECT AddressLine1, City, StateProvinceID, PostalCode FROM Person.Address a INNER JOIN HumanResources.EmployeeAddress e ON a.AddressID = e.AddressID WHERE e.EmployeeID = @EmployeeID ) GO After it has been created, the new inline UDF is then used in the FROM clause of a SELECT query. The @EmployeeID value of 2 is passed into the function in parentheses: SELECT AddressLine1, City, PostalCode FROM dbo.udf_ReturnEmployeeAddress(2) This function then returns a result set, just like when you are querying a view or a table. Also, just like a view or stored procedure, the query you create to define this function must be tuned as you would a regular SELECT statement. Using an inline UDF offers no inherent performance benefits over using a view or stored procedure. java qr code reader zxing QR Code Reader & Scanner for Java - Opera Mobile Store

Compile a sample application to ensure that GCC still works correctly. 10. Reboot. That is all there is to it! Depending on your system s configuration, the process might require relinking or rebuilding your system s library cache, but upgrading Glibc is nowhere nearly as complex as it was during some of the major Linux library upheavals, such as when Linux systems converted from using libc version 5 to version 6, or when the executable binary format of all Linux applications changed from a.out to ELF. You may also find that you need to relink or update some of the applications that you may have compiled for your system if they have dependencies on misfeatures of previous functions in the Glibc library or related libraries. Subsequent sections discuss these steps in more detail, walking you through all of the nuances of each stage. Sections where you might encounter a problem contain sidebars discussing these potential problems and provide workarounds. Multi-statement table UDFs are referenced in the FROM clause just like inline UDFs, but unlike inline UDFs, they are not constrained to use a single SELECT statement within the function definition. Instead, multi-statement UDFs can use multiple Transact-SQL statements in the body of the UDF definition in order to define that a single, final result set be returned. The basic syntax of a multi-statement table UDF is as follows: CREATE FUNCTION [ schema_name. ] function_name ( [ { @parameter_name [ AS ] [ type_schema_name. ] scalar_parameter_data_type [ = default ] } [ ,...n ] ] ) RETURNS @return_variable TABLE < table_type_definition > [ AS ] BEGIN function_body RETURN END Table 11-3 describes the arguments of this command.
