I want to cut out a fragment of a vector file. What coordinates shall I use to specify its borders?

Alexander — Fri, 05 Sep 2008 07:04:03 +0000

To ensure correct operation of the application, borders of a vector file fragment in Cut Segment field shall be set using the same coordinate system as the one used for setting coordinates of points in the vector file. For vector layers with points coordinates set in LatLong system the Cut Segment field shall be used to specify minimal and maximal values of latitude and longitude of the fragment to be cut out. If coordinates of vector file points are set in meter coordinates then the fragment borders shall also be indicated in meter coordinates.

I have a group of vector files in ESRI format, Can I convert the group of files into MapInfo format in one go?

Alexander — Fri, 05 Sep 2008 07:03:19 +0000

Vector Converter application supports data batch processing therefore you can add all required vector files in the list of input files and perform their conversion in one go.

Can I combine two vector files in one layer?

Alexander — Fri, 05 Sep 2008 06:18:00 +0000

In order to combine two vector layers using Vector Converter application you need to give them the same name and add them to the list of input files. Then select Append in the drop-down list “If Exist” and press Convert.

Does ActiveX Compete with Java?

Alexander — Mon, 21 Apr 2008 12:12:48 +0000

"ActiveX is an integration technology, while Java is an Internet language."—GIGA Information Group, June 6, 1996

ActiveX and Java™ are complementary, not competing, technologies. First and foremost, Java is a programming language. Second, Java is a set of virtual machine bytecodes that can be executed on any platform running a Java Virtual Machine (VM). Third, Java is a set of programming interfaces that define the underlying services available from Java code.

ActiveX, on the other hand, provides a totally different set of benefits focused on integrating objects created in any language. That means that ActiveX makes Java more powerful by enabling it to access code written in any other language. This gives Web designers the flexibility to include multiple objects in a page (some built in Java, some in other languages) and have them communicate interactively.

Isn’t ActiveX Just a New Name for OLE?

Alexander — Mon, 17 Mar 2008 10:04:07 +0000

While Microsoft® ActiveX™ and OLE are both based on the Component Object Model (COM), they provide substantially different services to developers. COM provides the low-level object-binding mechanism that enables objects to communicate with each other. OLE uses COM to provide high-level application services such as linking and embedding to enable users to create compound documents. ActiveX, on the other hand, provides a substantially "slimmed down" infrastructure to enable controls to be embedded in Web sites and respond interactively to events. While OLE is optimized for end-user usability and integration of desktop applications, ActiveX is optimized for size and speed. ActiveX also adds a number of important innovations for the Internet, including a substantial (50 percent to 75 percent) reduction in size, support for incremental rendering and asynchronous connections.
