Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: wixui Group: v3.0 Status: Open Resolution: None Priority: 4 Private: No Submitted By: Simon Harrison (ssmmhh) Assigned to: Bob Arnson (barnson) Summary: Irritating flicker when launching an installer with WIXUI Initial Comment: I don't know if this is specific to Win2k3 (which I'm running it on). I took the latest version and modified wix\examples\first\product.wxs, added WIXUI_INSTALLDIR property and UIRef element. You could live with it for the odd open-source project, but I think for any commercial use this would be unacceptable. The flicker is still there in v3 but different in nature. ---------------------------------------------------------------------- Comment By: Mike Green (ferrysoft) Date: 2007-02-10 00:17 Message: Logged In: YES user_id=1108842 Originator: NO I think the all too brief display of the two modeless dialogs that Bob describes will occur, even on installers with a realistic number of files. For example, I’ve got an installer containing about 120 files. I can offer two example experiences, using that installer: On a 450 MHz PC with 256 MB RAM, only the first dialog displays its text, long enough to read. It is quite easy to discern the first dialog as it is a different size to the second dialog. The second dialog is indistinguishable from the modal dialog and there is just a fleeting feeling that some text has been displayed and then been blanked out. I’d still describe the visual appearance of that as a ‘flicker’. On a faster 2 GHz PC with 1 GB RAM, the first dialog is just discernable by its different size but the text isn’t displayed long enough to read. The second dialog is too fast to even generate a ‘flicker’. So, in the real world, I’d suggest that there will be a range of installation scenarios. At one end will be some that flash up the modeless dialogs almost too quickly to notice, and leave you feeling as though the installer is buggy. At the other end will be some that display the modeless dialogs long enough to comfortably read them. The challenge is to make the WiX modeless dialog behave reasonably across that wide range. Perhaps the WiX modeless dialog could have a minimum display time. Better still, perhaps it could only appear if the process that it is covering will take longer than a certain threshold time. ---------------------------------------------------------------------- Comment By: Simon Harrison (ssmmhh) Date: 2007-02-09 22:45 Message: Logged In: YES user_id=775521 Originator: YES Yes, flicker, was perhaps not the ideal choice of words. Once I had added extra files to the installer, I then got to read the dialogs, so I guess that's the work-around. Since there will be very few installers that will be so small in size, I guess it's not really a bug. Might be worth a FAQ entry, to re-assure people trying out wix for the first time though. ---------------------------------------------------------------------- Comment By: Bob Arnson (barnson) Date: 2007-02-09 18:28 Message: Logged In: YES user_id=26581 Originator: NO There are two modeless dialogs that appear in a typical WixUI installer before the "hi, I'm the wizard" modal dialog with a Next button. The first comes from MSI and says "preparing to install." MSI shows it while it opens the .msi and determines what kind of UI is authored (and many other things). The second is a "preparing" dialog that stays up during AppSearch, costing, and so forth. With fast IO (e.g., local drive -v- network) or a small package, those dialogs appear and close quickly. I wouldn't call it flicker but the preparing dialog and the first modal page have a similar layout, so making them look very different might help prevent it looking like it's one dialog. I'll keep this bug open for future work. ---------------------------------------------------------------------- Comment By: Mike Green (ferrysoft) Date: 2007-02-09 12:14 Message: Logged In: YES user_id=1108842 Originator: NO I’ve noticed this issue as well. I think it is due to the text in the initial setup window changing very quickly. Initially it displays: "Please wait while the Setup Wizard prepares to guide you through the installation. Computing space requirements" That text is then replaced with: "The Setup Wizard will install <Application Name> on your computer. Click Next to continue or Cancel to exit the Setup Wizard." On my system, the text changes almost instantaneously. It happens so quickly that it took me several attempts to capture a screen image of the initial text. The rapidity of the text change produces a flicker effect from the user’s perspective. ---------------------------------------------------------------------- Comment By: Bob Arnson (barnson) Date: 2007-02-09 06:16 Message: Logged In: YES user_id=26581 Originator: NO I can't really comment about the problem without more detail. What flickers? ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=642714&aid=1655432&group_id=105970 ------------------------------------------------------------------------- Using Tomcat but need to do more?
