Hello,

I am using Codejock SuiteX (SuiteControls), and I am trying to change the BackColor property of the Preview control. However, no matter what value I set, the background always stays white. Unhappy

IDE: Visual Basic 6.0 with SP6
OS: Windows Vista both Windows 11

Is there a known issue with the Preview control’s BackColor property, or is there an additional step required to make the background color change take effect?

Thank you in advance for your help. Smile

Hello,

I'm glad to inform you that the issue has been addressed and fixed. The fix will be available in the next beta or final release.

At now you can change color by VB6 options

Dear Artem,

Thank you for the update and for fixing the .BackColor issue in the December 31st release! I've confirmed that the background color now updates correctly.

I have one follow-up question below, regarding the Preview control.

Once a file or image has been loaded, I'm not sure how to properly "unload" it to revert the control to its original empty state.
Could you please let me know the best way to:

Clear/Unload the current content from the viewer?
(To bypass this, I'm loading a minimal dummy file (a.jpg) of the same background color into the Preview control to act as a reset.)

I want to make sure the control is completely reset and the memory is cleared before loading the next file.

In addition to the above, I would like to request a property that indicates the control's current state: specifically, a Boolean property (True/False) to determine if a file is currently loaded, or a property that returns the full file path if a file is present.

Any advice or a quick code snippet for VB6 would be greatly appreciated!

Best regards,

Norika
