>>>>>>I went a lot further. Please download my version:

>>>>>>
>>>>>>
>>>>>>Here are the main changes:
>>>>>>
>>>>>>- Allow the mouse to slide in horizontal and vertical
>>>>>>- Added the Value property
>>>>>>- Added the "Scrolled" event, to make it compatible with the ActiveX from CTL32 (This will eliminate "ValueChanged")
>>>>>>- Recreated the Track images, making it much taller / wider, in order to keep the appearance when the control is big.
>>>>>>- Value assignments. Now you can assign a value directly to the control, and the slidebar will automatically update its position.
>>>>>>
>>>>>>
>>>>>>- Some other various minor tweaks.

>>>>>>
>>>>>>There are still some things missing:
>>>>>>
>>>>>>1 - to code the horizontal lines
>>>>>>2 - To enable "Small Change / BigChange"

>>>>>Very nice. I'll do the horizontal lines now.

>>>>>As far as the Small/Big change, I have already added a property called iIncrementStyle, where

>>>>>I'm also going to put code in the MouseEnter and MouseLeave to change the color of

>>>I noticed that you added a Value property, with Access and Assign methods. I'm guessing

>>>Sound Ok?

>>
>>Yes, I noticed that.

>>I replaced the iValue for "Value" just to make it compatible with the CTL32 ActiveX.

>>Also, I removed the event "ValueChanged", and replaced it with "Scrolled" that is the name that the CTL32 Control uses.
>>
>>They all do the same thing...
>>Choose the way you prefer.

>>Another point to think:
>>The way aI coded, Value / iValue can be range only between 0 and 100. Maybe the best is to allow the user to define the ranges, and the control will automatically update itself.

I just fixed a couple of bugs. Please redownload the ZIP
Everything makes sense in someone's mind

In addition, an integer field is not for irrational people
