Description

Validate makes data validation much easier.  This control allows you to collect all of the data validation code for a form into one event procedure.  This results in smaller and more maintainable code.

Validate only works with controls that have an hWnd property.

FAQ - How does Validate work?
How does Validate work?

Frequently Asked Questions

Validate uses the fact that when the focus of an object changes in Windows, two objects are relevant -- the object that had the focus and the object that is about to receive the focus.

The Validate control works by monitoring a list of objects that are defined by the AddControl method. When the focus of an object is about to change AND the object that has the focus is part of the validation list, the Validate event is fired. The Validate event has three arguments:

CtrlValidate - this is the object that has the focus and is about to lose the focus.

CtrlWantsFocus - this is the object that did not previously have the focus, but is about to receive the focus, assuming this object had been added to the list via the AddControl method. If the object that is about to receive focus had not been previously added to the list, then CtrlWantsFocus will be the same object as CtrlValdate.

Action - this can be used to intercept the request to change focus and return the focus to the object specified by CtrlValidate.


FAQ - Could you please clarify "CtrlWantsFocus.Name" for me?
Could you please clarify "CtrlWantsFocus.Name" for me?

Frequently Asked Questions

When a data type is defined as an object (as are both CtrlValidate and CtrlWantsFocus), all of the object's properties can also be referenced. CtrlWantsFocus.Name would be the Name property of the object that is about to receive the focus (assuming this object was added to the list with the AddControl method).


FAQ - Is CtrlWantsFocus the control that has focus when the validate event is fired?
Is CtrlWantsFocus the control that has focus when the validate event is fired?

Frequently Asked Questions

No. The event is fired before the focus changes.  The CtrlValidate is the object that currently has the focus, and the CtrlWantsFocus is the object that is about to receive the focus.

AddControl Method


AddControl Method

See Also            Frequently Asked Questions

Description

Adds a control to the list of controls to validate.

Syntax

object.AddControl control

The syntax of the AddControl method has these parts:

Part	   	Description

object	Required. A Validate control.

control	Required. A control for the Validate Control to monitor (must have an hWnd property).

Remarks

Use this method to add a control to the list of controls that the Validate control will watch.  The Validate control will do nothing unless controls are added.  The Validate control will fire the Validate event when the watched control loses focus (such as when the user presses the Tab key or uses the mouse to switch controls).

Typically you should add edit boxes, list boxes, check boxes, etc. (i.e., add input controls).  Labels, picture boxes, etc. should not be added.

Only controls with an hWnd property should be added.


Validate Event

See Also            Frequently Asked Questions

Description

Fires when focus is lost from one of the watched controls.

Syntax

Sub object_Validate([index As Integer,] CtrlValidate As Object, CtrlWantsFocus As Object, Action As Long)

The syntax of the Validate event has these parts:

Part	   	Description

object	A Validate control.

index	An integer that identifies a control if it's in a control array.

CtrlValidate	The control that needs data validation.

CtrlWantsFocus	The control where focus will shift.

Action	A boolean expression that determines if focus remains with ctrlvalidate.

Remarks

This event fires when one of the watched controls (see AddControl Method).  The control that currently has focus is specified by CtrlValidate.  This is the control on which you should perform validation.

The control that is about to gain focus is specified by CtrlWantsFocus.  If this control is a command button, you may need to do some special processing in the button's Click event to prevent processing.

If you do not want focus to switch from CtrlValidate to CtrlWantsFocus then set the Action to True.  This will force the focus to return to CtrlValidate.  Otherwise, focus will switch normally to CtrlWantsFocus.

Note: If the user switches focus from a control that's being watched (validating) to one that is not, CtrlWantsFocus will be the same as CtrlValidate.


Version Property

Frequently Asked Questions

Description

Shows the version of the control.

Syntax

object.Version

The syntax of the Version property has these parts:

Part	   	Description

object	A Validate control.

Remarks

This property holds the current version of the control.  It is read-only and available at both design-time and run-time.

Licensing Information

Legalese Version

Mabry Software grants a license to use the enclosed software to the original purchaser.  Copies may be made for back-up purposes only.  Copies made for any other purpose are expressly prohibited, and adherence to this requirement is the sole responsibility of the purchaser.

Customer written executable applications containing embedded Mabry products may be freely distributed, without royalty payments to Mabry Software, provided that such distributed Mabry product is bound into these applications in such a way so as to prohibit separate use in design mode, and that such Mabry product is distributed only in conjunction with the customers own software product.  The Mabry Software product may not be distributed by itself in any form.

Neither source code for Mabry Software products nor modified source code for Mabry Software products may be distributed under any circumstances, nor may you distribute .OBJ, .LIB, etc. files that contain our routines. This control may be used as a constituent control only if the compound control thus created is distributed with and as an integral part of an application.  Permission to use this control as a constituent control does not grant a right to distribute the license (LIC) file or any other file other than the control executable itself. This license may be transferred to a third party only if all existing copies of the software and its documentation are also transferred.

This product is licensed for use by only one developer at a time.  Mabry Software expressly prohibits installing this product on more than one computer if there is any chance that both copies will be used simultaneously.  This restriction also extends to installation on a network server, if more than one workstation will be accessing the product.  All developers working on a project which includes a Mabry Software product, even though not working directly with the Mabry product, are required to purchase a license for that Mabry product.

This software is provided as is.  Mabry Software makes no warranty, expressed or implied, with regard to the software.  All implied warranties, including the warranties of merchantability and fitness for a particular use, are hereby excluded.

MABRY SOFTWARE'S LIABILITY IS LIMITED TO THE PURCHASE PRICE.  Under no circumstances shall Mabry Software or the authors of this product be liable for any incidental or consequential damages, nor for any damages in excess of the original purchase price.

English Version

We require that you purchase one copy of a control per developer on a project.  If this is met, you may distribute the control with your application royalty free.  You may never distribute the LIC file.  You may not change the product in any way that removes or changes the requirement of a license file.

We encourage the use of our controls as constituent controls when the compound controls you create are an integral part of your application.  But we don't allow distribution of our controls as constituents of other controls when the compound control is not part of an application.  The reason we need to have this restriction is that without it someone might decide to use our control as a constituent, add some trivial (or even non-trivial) enhancements and then sell the compound control.  Obviously there would be little difference between that and just plain reselling our control.

If you have purchased the source code, you may not re-distribute the source code either (nor may you copy it into your own project).  Mabry Software retains the copyright to the source code.

Your license is transferable.  The original purchaser of the product must make the transfer request.  Contact us for further information.

The sample versions of our products are intended for evaluation purposes only.  You may not use the sample version to develop completed applications.
