You asked for more information about web processes to better identify requests that might be slowing down or blocking your server. We heard you and in 4D v17 R5, we’ve added information about the URL used by web processes. This information can be retrieved two ways: via the 4D Server Administration Window or via the 4D language with the Get process activity command.
Typically, 4D View Pro requires that you identify the cell being worked with and where data will be entered (the active cell). You may also need to select some cells and then perform an action, such as formatting or entering values in them. 4D v17 R5 provides a new set of commands to help you manage both the active cell and cell selections.
Custom headers are useful to add information that may not be supported with standard properties. In 4D v17 R5, we’re not only giving you a set of predefined headers, but also a way to declare customized headers to the mail object.
You asked for a way to run multiple clients on the same computer AND simultaneously connect them to the same 4D Server. We not only heard you, we’re giving you even more with 4D v17 R5! Each connection now includes a separated cache folder containing the connection’s IP address, port, and a hash code. Thanks to this, you can now also connect several clients from the same machine to multiple servers on different machines. There’s no configuration necessary, just launch and watch it work!
In addition to the existing toolbar, we’re proud to announce the addition of a very powerful ribbon-style toolbar to enhance the 4D View Pro user interface. Just select an option in the Property List and you’re off and running!
As promised in a previous post, each R-release includes more advances related to email functionality, unlocking its hidden power.
4D v17 R5 provides an interesting new feature for email logs. Sometimes during development everything works fine but when you deploy to the customer, there’s a problem delivering emails. Discovering where the failure occurs can be difficult, since the communication is encrypted and you often don’t have access to the SMTP server log files. The problem is very likely related to your SMTP server, but how can you be sure? Simply start the SMTP log in your application! This log contains a record of all the actions performed, including those stopping the connection. Even better, this log shows the communications with the SMTP server in plain, non-encrypted text, making it easier to analyze.
4D v17 R4 is on the way with a cool new 4D View Pro feature: named ranges and formulas. If you need to use formulas with references to cell(s) or constant(s), this feature can be a great help!
With these new commands, your formulas are more readable and easily accessible with 4D View Pro’s automatic completion.
Preemptive processes are very useful for performing extensive calculations in parallel, using all of the cores in your CPU, but sometimes you need to delegate tasks to a cooperative process (e.g., using a non-preemptive command). With the New signal command, you can pause a process and wait for the response from another process!
The ability to interact with a document via programming is an important part of using 4D View Pro. Now you can fill your documents by programming. You can set data as labels, database fields, or formulas in your document. Of course, if you can set, you can get too! You can also retrieve cell formulas or values entered by your users.
4D v17 R4 brings new features to 4D View Pro and one of them is the creation of ranges with code.
First, you need to define a range object to manipulate your cells by programming. You can do this in 4D View Pro with the following new commands: VP Cell, VP Cells, VP Column, VP Row, VP All and VP Combine ranges.
