HOW DO I
Compare PicturesData HandlingThe function returns "true" or "false" depending on the result.
It also builds a mask that shows you the differences between the pictures you compare.
Database EventsDatabaseThe new events supported by this new method apply to background or foreground application moves.
File Management EnhancementData Handling- COPY DOCUMENT
- CREATE FOLDER
- DOCUMENT LIST
- System folder
- Select document
This "How Do I" covers all of the above commands.
Get DigestData HandlingPart of this functionality was previously available in 4D Pack, using the MD5 algorithm and applied only to documents.
The new 4D command will be able to use two different algorithms (MD5 digest and SHA1 digest) and apply it to variables.
Here you have an example of how it works on a variable and how to manipulate it on a document.
Get List Item ParametersDevelopment EnvironmentPrevious to 4D v13, to retrieve a parameter value, you had to know the parameter name and use the GET LIST ITEM PARAMETER command.
With the new GET LIST ITEM PARAMETER ARRAYS command, you can retrieve all parameter names and parameter values.
Get Query DestinationDevelopment EnvironmentWe added the command GET QUERY DESTINATION to allow you to know where the result of the current query has been placed for the current process, and the command GET QUERY LIMIT that lets you know whether or not there is a limit for the query.
We've also added a new parameter for the command SET QUERY DESTINATION: A pointer to the local variable, when the destination type is a variable.
Get Text KeywordsDevelopment EnvironmentGET TEXT KEYWORDS(theText ; the TextArray) fills an array with all words within the text.
GET TEXT KEYWORD(theText ; the TextArray ; *) fills an array with all unique words within the text.
Getters and SettersDevelopment EnvironmentThis demo shows you how to use these new getters and setters and their associations.
HTTP ClientConnectivityThis "How Do I" covers the various commands that are used with the new HTTP client.
Picture Names in PicturesMetadataWhen you drop or import a picture into a 4D variable or field, 4D reminds you of the name of the original file.
This name will be used by default in the system "save file" dialog when the command "Save picture file" will be called or when using the contextual "Save as..." menu.
The file name saved inside the picture can be modified or simply read using the new commans PICTURE SET FILENAME and Picture get filename.
Progress BarUser InterfaceThis demonstration shows you how to use the progress bar component that is included as of 4D v13.
Selection to ArrayDevelopment EnvironmentThis demo shows you how to use them.
Stats FunctionsProductivityThis "How Do I" demonstrates how to use statistical functions on arrays.
Web Get Body PartConnectivityThis demonstrates how to use this command to get a file via the browser.
Webkit IntegrationInternet & MobilityAs a result, Web pages will have the same appearance and behavior on both platforms, ignoring Internet Explorer on Windows.
This demo shows how web interfaces look under the Webkit rendering engine.
Windows EnhancementUser InterfaceThis allows you to move a specified window to the passed coordinates and set it as a foreground window. The command now accepts a * parameter to keep the window in the background.
XPS Print PreviewProductivityThis "How Do I" gives you an example of a direct print preview.
On Windows, if a print job is launched with the Print Preview checkbox selected, 4D redirects printing to the Microsoft XPS viewer.
Please note: Under Windows XP, Microsoft's .Net framework is required.
