Hi !
I'm using VB6 and i try to find a way to show a PNG file on the screen with transparency as a splash screen...
I've found a method to make transparent some colors on a form but not to show a PNG (with levels of transparency)...
In fact i wish to "simply"
 show a PNG (with transparency) on the top of the screen, like Windows Live Mail : It is real PNG with levels of transparency :
 Any idea ?

Hi, You could use a popupcontrol for this. You can set the transparency as well. Adding icons, buttons and hyperlinks is an option. It's worth trying |

Thanks, but i think on popcontrol you can only use one level of transparency.
In fact a need many levels of transparency on the same form at the same time (0% on center and more on borders).
I found a way (api) to use a color which would be transparent (pink for example) but no way to use levels of transparency (like in a png file). I'll keep searching and tell you if i find something.
Regards,

Hi,
Try this:
wndPopupControl.SetSize 300, 500
wndPopupControl.Bottom = Screen.Height / Screen.TwipsPerPixelY / 2 + wndPopupControl.Height / 2 wndPopupControl.Right = Screen.Width / Screen.TwipsPerPixelX / 2 + wndPopupControl.Width / 2 Note: setting a different display resolution your "splashscreen" size has to be adjusted to fit the display (if size of splashscreen is bigger than display resolution)

Hi,
I was playing around with the popupcontrol myself and if I may say so myself, its a splendid idea. It could be a nice feature for all of us having a transparent splashscreen. When using a background image the borders are even transparent, so you are able to make an irregelar shaped splashscreen !!!! and you can even drag the splashscreen !!!!
Now, this is for Oleg:
To make it even nicer could it be possible to have the option to add CUSTOM items. I think the same way as you attach a control to a commandbardropdown. If this is too much to ask, could we have just the progressbar option.
In my case the startup takes some time to load all the data and I want to show the user that there's something happening and I think I'm not alone with this.

I agree ! It's a splendid idea :)
Now that I have exactly what I wanted I looks forward to the release of official V12 to deploy. Let us hope that it will not be long any more!
Thank you for everything.

Hi,
When you have to build a splashscreen from scratch it will be difficult to get the buttons and images on the right place. But maybe this will give you an example how to create a splashwindow.
Start application will show splashscreen and after 10 sec the splashscreen will fade and application will be closed.
Adjust the controls in frmSplash and see what happens or add labels / pictureboxes (don't forget to load an image)

Hello !
I've just noticed a problem about this...
The popup control reacted like a... popup control and not really like a splash screen...
For example, if you let the cursor on the "splash screen" the popup control will never unload... try with the "layer" sample in the samples folder.
Any ideas ?

I've found a solution by using a timer calling the "close" function of the popup control. Not perfect but it works...
It will be great if CJ can add a "Enabled" (or other...) in order to disable the "mouse over" detection...

I agree with Lodep59 as there is another problem - not only will the control not close automatically, but it will go to 0% transparency on mouse over...this can cause a distracting flicker when the image fades in if the mouse is over the picture area. Some way to turn off the mouse detection is required for splash screen use. ------------- Product: Xtreme SuitePro (ActiveX) version 16.2.6 Platform: Windows XP - SP3 Language: Visual Basic 6.0 SP6 |

It would be great if we had a property to ignore mouse-over on the PopupControl so that it will not jump to 0% transparency for use in splash screens. Any chance of this for 12.1? ------------- Product: Xtreme SuitePro (ActiveX) version 16.2.6 Platform: Windows XP - SP3 Language: Visual Basic 6.0 SP6 |

Using PopUp Control as a Splash screen. This works well -- thanks Aaron. When run under the IDE, the PopUp form reacts to mouseOver -- transparency goes to zero and the buttons light up. But when compiled the form does not react to mouse over. As if it was not enabled So the buttons do not work. Has anyone else found this difference between IDE and compiled program.? ------------- Chris (Manchester, UK) -- www.abc6.co.uk ---- Using CodeJock ActiveX Suite 13.1.0 with Windows8, VB6 SP6 |

In my tests the popupcontrol transparency goes to zero even in the compiled program, and I find this behaviour very distracting for the purposes of a splash screen. Any chance that we can either: 1) Have a property to ignore the mouse over transparency change, or 2) Have access to the Hwnd so that we can subclass the PopupControl and consume the mouse messages?

Pretty please with sugar on top? It can't be more than an IF block and a boolean property declaration to get this to work can it? ------------- Product: Xtreme SuitePro (ActiveX) version 16.2.6 Platform: Windows XP - SP3 Language: Visual Basic 6.0 SP6 |

Hi All!
I vote for this little feature to be implemented. I tried to use the Region of the FormExtender control for this reason but it generates an error if we select a png file. ------------- Product: Xtreme SuitePro (ActiveX) version 15.2.1 Platform: Windows XP SP2 Language: Visual Basic 6 SP6 |
