Changer le fond d'écran windows

Bonjour,
Je cherche à changer le fond d'écran windows en dynamique dans un VI.
En clair si l'utilisateur fait tel ou telle action, son fond d'écran windows change.
Quelqu'un connaitrait-il une librairie ou une méthode pour cela?
Merci d'avance

I'm confused but it might be because of my limited French. You want to change the wallpaper of the Windows desktop or a VI front panel? The first is done using a Windows API call
SystemParametersInfo(SPI_SETDESKWALLPAPER,0, pathp, SPIF_UPDATEINIFILE);
See here for a ready made VI to do this.
The second is done using a VI Server property.

    If I read the translation properly, I think that the iPad may have switched app stores when you updated the iOS. If that is what happened, change to store to your store.
    Launch the App Store app and swipe to the bottom of the screen in the featured tab. Tap on your Apple ID. Then tap on View Apple ID in the window that pops up. Enter your password. Then go to Country/Region in the next pop up window and tap the flag in that line to take you to a window where you can change to your country's store.

  • How to change fonts in the Finder window

    How does one change change fonts in the Finder Window?
    I've done it before and I know it's different in the Side Bar and for the fonts in Column View or List View.
    It doesn't seem to be in Finder Preferences.
    I can't find in in System Preferences.
    It's not in Font Book.
    Where is it???
    TIA

    If you click the Action Gear you have the option to change font sizes. I am not sure if changing the font per se is possible without a system hack which I do not recommend.

  • How to change background color in AutoComplete window ?

    Is it possible to change background color in AutoComplete window ?

    Bob, A.Ankit, you're both chasing a ghost here.
    The screenshot shows an autocomplete enabled textbox with its dropdown list of autocomplete values to choose from. There is no property defining its backcolor. Not in the textbox nor in any class, neither any other baseclass nor _combobox of _base.vcx
    The only way to chnage that color is not recommended, via changing windows theme colors. That would effect any window and control.
    If you need another color even turning off themes won't help as VFP doesn't offer any property controlling that color, so you really would need to implement the autocomplete feature yourself, if you want the specify this backcolor.

  • CS3 - Change magnification of Source/Program windows?

    I'm working in Premiere Pro CS3 and I've successfully imported some video.  I can change the size of the windows themselves (50%, fit, etc).  However, the image itself inside the windows continues to display at 100%.  This means that at the "fit" windowsize, I'm seeing the top left corner of the image only.
    When I stop the video playback and click on the video itself, I see a set of scale controls over the image, which looks perfectly scaled to the window size.  But as soon as I engage playback, the video blows up to 100% size inside a small window, leaving me without a clear look at my full footage.
    I'm a Photoshop person and I'm looking for the equivalent of the Zoom tool to get a larger or smaller view of the full video.  Is there a way to change this, or is my only option to open out the panels as large as possible to see the whole picture?
    Thanks, I hope this makes sense.

    MandyRose,
    With a Project Preset of Desktop (Custom) set to 640 x 480 PAR = 1.0 (Square Pixels) and matching source footage, which the info in Project Panel verifies, this should not be happening. Going back to your Project Preset, can you check one more time that you have chosen Desktop, with the above specs. ? What you show is what one would get with a mismatch between the Project Preset and the source footage. That's why I'm bothering you with that one bit. I've thought that I had chosen properly, experienced similar, only to find that I had clicked one selection above, or below, or forgot to change my Frame Size in the dialog screen. In the Toolbar, you can go to Project>Project Settings and display the General settings chosen for the Project.
    if I set my view to something larger than my screen can display (for example, 75% or 100%) it stretches and distorts the image within the size of the panel.
    That other magnifications show only a portion of the source footage's Frame Size is correct. Depending on the size of the Program Monitor, one would have to scroll around higher magnifications, when they are chosen, instead of Fit. That it "stretches and distorts" is not.
    I realize this just might be a limitation of Premiere that it always displays this way, but it just seems as though it should show me the full clip (reduced to fit the window) while I'm working with it.
    PrPro's Program Monitor is an emulation, albeit a pretty good one. This is not normal behavior. That is why I'm looking for one setting that is not correct.
    In the Timeline, Rt-click on the Clip, and check whether Scale to Frame is checked. If so, what happens if you uncheck it?
    One other place to check would be the Effects Control Panel and twirl-down Motion, looking at Scale, to make sure that nothing has been applies there. Scale should be set to 100%.
    That is all that I can think of at this moment. I'm sure that I am missing other places to check. If I can come up with any, I'll post them back with more questions.
    Good luck,
    Hunt

  • [ dwm ] How to change the wallpaper and make windows transparent ?

    How do I change the wallpaper and make windows transparent ( ~ 20% ) ?
    Have been Googl'ing for a while now but still have no clue on how to achieve it

    What terminal do you use? urxvt can set transparency in the Xdefaults file.

    Or, if you don't like fiddling with Xdefaults file, you can simply make urxvt transparent by executing it like "urxvt -tr -sh 20", where the number represents the transparency level. However, this is only pseudo transparency, but I like it better than resource-consuming compositing.
    Will give it a try. I'm not against .Xdefaults - just haven't used it that much and know only the basics ( color schemes )

    "You have to change your router's IP address to be able to access it. It will not give you the internet."
    I'm not sure what that means Richard, but I did change the router's IP address from 192.168.1.1 to 192.168.5.1- isn't that what you meant in your first post. I know that isn't reflected in my screen capture that I took last night, but I did do that this morning after I read your post.
    "Log on to your router and change two settings.
    Change the setting in Setup from PPPoE to Automatic Configuration-DHCP and click on save.
    Click on Advance Routing and change the setting from Gateway to Router then click on save."
    I did this and still same results as far as I can tell. Can't get online through the router.
    "Click on MAC address clone under setup tab ... click enable & click clone ...click save settings ... Check the IPaddress under WAN page ....
    If getting IP in public range .... try going online ...."
    I tried this- at least to the part about checking the IP address under WAN. I assume you mean the WAN page in the modem setup- nothing looked any different after trying what you suggested, and I'm not really sure where I would be "getting IP in public range" or what that means.
    I'm about to give up and just buy a new router to see if I can get the same lack of results with a different one. My ISP maintains that everything is set up correctly on their end and really can't do anything more for me. The Modem works and is set up correctly and they can give tech support for a router.
    Here's what my basic setup looks like now:

  • How do i change the color of the window background?

    How do I change the color of the window background? When I create a new document on indesign sometimes the blackground is white, sometimes black or gray and I d'ont know why. Thanks for help.

    THis sounds like you are viewing is different modes. "Normal" or layout mode uses a white pasteboard whre you can store objects that you might want to use, but don't want on your pages currently. When you switch to "Preview" mode the pasteboard and any guides and non-printing objects disappear and the background goes gray. In Presentation Mode the backbround is black and the tools and panels will disappear.
    Hitting the W key when you don't have the Text tool active will toggle normal and preview modes. Shift + W will take you to Prensetation Mode, and Esc will take you back out.
