ERRORPROVIDER BLINK RATE HOW TO

ERRORPROVIDER BLINK RATE CODE

I check if the error is to be set or removed depending on the length.

When SetError is called on the ColoredErrorProvider: This is indirectly manipulated through the public property BlinkCount. The BlinkCountArray contains only one entry. If somebody would enlighten me about a better way to do this, it would be great.

ERRORPROVIDER BLINK RATE HOW TO

I didn't know how to change the value of a primitive type that is a member of a structure and which is returned as a key's value from the HashTable. The BlinkCountArray is a hack workaround.

ERRORPROVIDER BLINK RATE CODE

Since all derivatives of the Control class will have a BackColor property, we override the CanExtend method to return true if the object is a Control:Д¬opy Code private Hashtable originalControlColors = new Hashtable() A visual designer can then call CanExtend to determine which objects in a container should receive the extender properties'. MSDN says 'Any component that provides extender properties must implement IExtenderProvider.

The ColoredErrorProvider extends a Control and implements IExtenderProvider which is necessary to implement your own extender provider. I will not be walking you through this code.

settleColor: The background color of the control when the blinking is over.Д¬lass Form1 is the example application form.

blinkColor: The color that is the background color when the control blinks.

The string itself is NOT displayed to the user like ErrorProvider does. If it is empty then it will not display the error.

value: If it is not empty then the control will blink.

control: The Control on which the error must be applied.

While setting the error, one can specify:

blinkInterval: The time in milliseconds between each blink.

blinkCount: The number of times the control will blink before it settles on the settle color.

While creating the ColoredErrorProvider, one can specify: Change the number of characters in this text field and take focus away from it to see the effect of the ColoredErrorProvider class. If it contains more than 10 chars, the error is set.

Clicking the 'Toggle Error' button sets/unsets the errors on the controls in the groupbox. The sample contains a small program with a few components that illustrate using this class. And of course, to learn how to write an Extender Provider. I wrote this because the icon I had to display using ErrorProvider could not be placed in any convenient location the icon overlapped with some other control or went out of the bounds of the form. What has been changed is that the error/warning is indicated to the user by flashing the control's background color. The class in this example is similar to the ErrorProvider class.

allow verification to be handled during processing.

This is very convenient considering that the alternative would be to: The ErrorProvider is a pretty neat control that allows you to display an error icon next to controls if the data in them is invalid. ToolTip1.SetToolTip( this.button1, ' this is a button') ToolTip1.SetToolTip( this.label1, ' This is a label')
