[ D2 | D3 | D4 | D5 ]
TDragSelect subclasses a target TWinControl descendant such as a form, panel, or scrollbox and intercepts the WM_LButtonDown, WM_LButtonUp, and WM_MouseMove messages. It uses these messages to control a click-and-drag focus rectangle of variable line thickness for the purpose of selecting an area within the target control. Upon completion, an OnSelect event is fired with the coordinates of the selected rectangle relative to the target control.

TDateTimePickerLink is a non visual Component, that is linking two DateTimePicker controls. If the value of the first DateTimePicker control is higher than the value of the second DateTimePicker control a message is shown and the changed value will be set to the value of the other DateTimePicker control. The message text is a published property. With the property MaxFromToValue it is possible to set a maximum value for the period of time. For a date the unit is 'day' and for time the unit is 'minute'. The message text displayed when exceeding the period is the published property MaxMessageText.

[ enablegp.zip ] [ 11,237 bytes ] [ Freeware ] [ With Source ]
[ D5 ]
I have often needed to enable/disable a number of components at once or open/close a number of tables/queries at once. To do it as a list of statements in your program is clumsy and open to errors if you change the number/names of the components. This archive holds two components: TEnableGroup and TEnableData that allow the grouping of components. Once grouped, common properties can be set with a single statement. The base component TCustomEnableGroup is also in the unit allowing many other "grouping" components to be defined.

[ fishotke.zip ] [ 2,415 bytes ] [ Freeware ] [ With Source ]
[ D2 | D3 | D4 | D5 | C3 | C4 ]
This component registers a system-wide key combination to the operating system. When the key combination is created anywhere in the operating system, this component will get the keypress first and call the OnHotKey event. The application does not have to be active or visible for the OnHotKey event to be fired. The HotKey property in our implementation consists of a TShortcut so that any key combination you can register in a normal shortcut, you can also register as a HotKey.
