This sample shows how to create images and move it with the mouse.

This is a sample arise a long time ago in the forums of a typical problem, in which a bottom image exists (Map) and are due to positione on this one others images as a "elements" (a pub and the tables, the plant of a hospital and the beds, a plane of a terminal and the positioning of machines...). It's a system to create objects and (in execution) to move using them the mouse.

This's a simple use sample of the API LockFile to detect active instances of an application. If you use a application in a network and you want to kwon wath instance of this application are running, this's a simple method.

Each aplication/station have a ID assigned (Integer) and you must use a shared file and the LockFile API to detect are runnig. It's very simple and effective.

Advantages:

• If a station/application terminate abnormally (CTRL+ALT+SUPR) the system release automaticaly their lock. No code is needed.
• The lock file always will have size 0 (bytes).

Components > Grids > Power Grids

Description

It allow to modify some aspects in the visualization of a standard Grid. It does not derive from the Grid, if not that works as complement to the standard component of Delphi.

Automatically can paint Boolean and memo columns like text and checkbox.

The Flat property allows to modify the aspect of the DBGrid.

In addition it provides events to modify colors of the DBGrid:

• OnPaintCell: In order to paint cells of a certain color.
• OnPaintCellExt: BIS of the previous one with more parameters.
• OnPaintColumn: It allows to paint a color column.
• OnPaintRow: It allows to paint one row out of color.
• OnPaintCellImage: It allows to paint images in a cell.
• OnChangeTitleCell: To modify the cells of title.

These events are independent and compatible with which it has defined the DBGrid. It is enough with loosen the control in the form, assigning the Grid to him and to activate it.

It allows to save the position and size from all components in a form.

The component uses a file INI. It is enough with placing the component in the form and activate it; When the application is closed save position/size and when returning to execute it restore the values to the controls automaticaly.

It's the perfect complement for the component TSelectOnRuntime (for move and resize components at runtime).

NOTE: The version 1.4 add the event OnNotExistComponent for made easy the work with components created at runtime. Now support added for Delphi 2005/2006.

NOTE: The version 1.3 allow the user add TStrings type properties like Lines, Items...
