Black screen at application startup

Hi,

we are seeing a black screen on application startup with new build (Actipro 9.1.0503).
It was running fine with the previous build(ActiPro 4.5.0487).What may be the possible reason? do we need to set any property to solve this?

one more issue which we are facing with the new build is that after application startup,application captures the whole screen even the space of task bar. How to avoid this?

Thanks,
Bala

For questions like this, please make a simple sample project that shows the issue and email that to us instead. Also indicate exactly which products you are talking about (you didn't mention any) and which operating system and theme you use.

While there have been updates/enhancements made to our products since v4.5, we're not aware of any of the issues you are describing. Do you see them with our samples in the Sample Browser?

If not, perhaps you customized the controls in some way (styles/templates) that doesn't work with more recent updates? That would be a good place to start looking on your own if our samples work fine for you, but your app doesn't.

Hi,


We are using
Product WPF Studio 2009.1(build 0503)
Operating System Windows XP SP2
Theme Office2007Blue


We are unable to re-produce same issue in Sample Application.

We have got a work around for Black Screen Issue by setting AllowTransparancy = True but it is not the actual solution. We have not set this property in previous version and no issue of Black Screen was there. Are there any changes with the new build regarding this?

We are not able to get any work around for full screen issue. At application startup window opens in the full screen, after one time minimize and maximize it gets normal that it should be. Any idea about this ?


Thanks,

Hi,

We are using,

Product WPF Studio 2009.1(build 0503)
Operating System Windows XP SP2
Theme Office2007Blue


We are now able to re-produce both the issues.We have tried it with product sample.
To re-produce these issues, open following filepath.

Drive:\.....\Actipro Software\WPFStudio\v9.1.0503\SampleBrowser\ProductSamples\RibbonSamples\Demo\DocumentEditor\MainWindow.xaml

In MainWindow.xaml, if you add

WindowState="Maximized" in ribbon:RibbonWindow tag


than you will be able to see following two problems on application startup when you Run Ribbon->Document Editor-> Run External Sample:
1. Black Screen appears for a moment.
2. After window loaded, it overlaps TaskBar

We investigated on this and did a workaround like, remove ResizeMode="CanResizeWithGrip" from the MainWindow.xaml ribbon:RibbonWindow tag
and problem got solved but window did not have Grip to resize.

We want both, Grip and MaximizedState.It was not the problem with the previous build.
Please check for this and let us know.

Thanks,
Bala

Bala,

Thanks for telling us how to repro it. An update in build 501 caused it. We should have it fixed for the upcoming build 504.
