Hi,

I have to implement a new class derived to CExtButton with a AutoRepeat function.

This function shuld enable the button to send a message continuously when its pressed and stops when its released.

I use this function in a program that controls and modify the colors of a bitmap, I use AutoReapet function to allow the users

to modify the property of a bitmap (RGB colors, contrast, ecc...).

Is there a simple way to implement it in your tools?

thanks for the answer and congratulation for the tool and the forum.

Thank you for the interesting question. Neither standard button common control nor our CExtButton extension provides ready-to-use support for continuously pressed button events similar to the up-down control attached to the numeric edit control. If you want this kind of button, then it should be implemented in the CExtButton-derived class where the mouse/keyboard processing is written from scratch. We can help you to code this button. Or we will just add this feature to our TO-DO list.

We also wonder how the color value would be changed when the user keeps this kind of button pressed? Typically the color parameters can be changed using up-down controls like up-down grid cells in the following sample application: http://www.prof-uis.com/download/samples/CompoundProperties-m.zip
