Dear pyi,
i tried to put scrollbar, it seems this is not possible.
But other solution is that i can make picture control larger than the line co-ordinates. I am attaching the same vi with few modifications.
Hope it helps. Your feedbacks are welcome.

This is called panning and you can find an example in this thread - http://forums.ni.com/t5/LabVIEW/Move-picture-inside-of-the-picture-control/m-p/623697?view=by_date_d...
The Code Capture Tool also includes an example of this in its source code (the preview of the capture can be panned), which also demonstrates one way of handling only some of the mouse move events (which is important, because usually there are too many events and you want to discard some of them).

Scroll bar does not appear in some PDF files. How can I enable it?

Scroll bar does not appear in some PDF files. How can I enable it?

Scroll bars are supposed to appear when needed.
For example, scroll bars will appear when you zoom in on a page.
FAQ: How to zoom in/out on a page
Windows 8 automatically hides scroll bars after a few seconds of inactivity. Scroll bars will reappear when you touch the screen and move your finger (on a Touch-enabled device) or move your mouse.
Additionally, page navigation depends on the view mode (Single Page vs. Continuous Page).
In the Single Page mode, you can swipe left/right (horizontally) or click the left/right arrow button with your mouse to go to the previous/next page.
In the Continuous Page mode, you can swipe or scroll up/down (vertically) to go to the previous/next page.

Vertical Scroll bar does not appear in table control

Hi ,
I have a table control with both vertical and horizontal scroll bars.
The data which comes is always more than 50 and the visible line size is 8.The vertical scroll bar
does not appear at times..but if i run the program again, it appears..
Sometimes it appears and sometimes no vertical scroll bar comes thought the data is more than the visible lines.
Any suggestions ? why is this happening?
Regards,
Sharadha

You have inserted data in the internal table and not "informed" the table control
In the PBO, use a statement like
DESCRIBE TABLE <itab> LINES <control>-lines.

And in panel 2, the content is added dynamically, so it cannot control the width. Once it is very long, then the UI will not show all the data in panel2, and panel 3 also cannot display.
So i want to the window have a scroll bar. How can i do this?
Thanks.

Hi Timo.
Thanks for your replies.
I change the panel 2 like this:
<af:gridRow marginTop="5px" height="auto" id="gr2">
                              <af:gridCell marginStart="5px" marginEnd="5px"
                                           width="100%" halign="stretch"
                                           valign="stretch" id="gc2">
                                 <af:panelBox text="panel 2"
                                              id="pb2">
<af:panelGroupLayout id="pgl4" layout="scroll>
</af:panelGroupLayout>
                                 </af:panelBox>
                              </af:gridCell>
                           </af:gridRow>
But it still cannot display a scroll bar for the panel 2.
Thanks.

I have a new mac pro and can't get a side scroll bar. How can I get this?

The scroll bar is now set to appear automatically when you start scrolling with a trackpad or scroll wheel mouse. If you are using an mouse without a scrolling device, you should change a setting.
In System Preferences, click General, and in the Show Scroll Bars section, click the option for how you want it to work. If you want to see them all the time click "Always."

Is there a way to hide the horizontal and vertical scroll bar?

Hi,
I have report with customized page height and width and I am displaying it in the windows forms.
When I am resizing the form wherein the crviewer is dock in, the horizontal and vertical scroll bars appears.
Is there a way for me to suppress the those scrollbars?
Thanks in advance.

Couple of ways I've been able to find info about. E.g.; there is not straight API off os the viewer (CRviewer.ScrollBar = False ).
1) Add Panel control onto the page and add report viewer control into a Panel. Set Scrollbar, width, height property of Panel control.
2) See http://www.dotnetspider.com/forum/266932-Remove-Scrollbar-from-Crystal-report-Viewer.aspx for another idea.
If either of the above works for you, please let us know as I have not tested this yet.

Scroll bars don't appear on Droid or IPad...

So I have a div on my webpage that has the Positioning -> Overflow set to Auto so that a scroll bar appears when the text overflows...the scroll bars work fine in Mozilla and IE, but when the site is viewed on a Droid or IPad, the scroll bars to not appear and the content in the div is simply cut off. Has anyone dealt with or seen this issue before? And are there any fixes? Thanks for any help in advance!
Also, is there a way to preview droid and ipad sites in Dreamweaver? Is there a download or add-on that will make those an option in Device Central??

Hi
First as I have previously said you never use floats on a page for mobiles.
The scroll bar you mention does not appear on mobile devices because if it did it would be totally unusable for almost everyone, (this is common on all mobile browsers).
Designing for mobiles requires a completely different approach than designing for a standard desktop browser, as one must remember that such things as the scroll-bar you mention would not have the required 'area' to be used by touch-screens or any way of getting focus in order to be used by a d-pad.
Even though media-queries are not recognized by older none smart-phone devices, their use would enable you to 'style' your content in order for viewing and usability on mobiles. Another example is that your main menu, (and entire home page) is virtually unusable without using zoom, (something many will not do) even on the Opera mobile browser, (the most popular browser in use for mobiles).
People use mobile devices 'on-the-move' even when browsing web sites, this means that in general only one hand is used, and the time taken to navigate is much more important than on a desktop, (were the user can use a mouse) thus the reluctance to use the zoom facility.

I am not quite sure if I understand what you are trying to do.
Sounds like you are trying to implement the zoom feature (increasing/decreasing the size of the picture inside a picture control, but not the size of the picture control itself). If this is what you are trying to do, then there is a property node in LabVIEW 7.0 that supports this feature (This property did not exist in LabVIEW 6.1). Please download the LabVIEW 7.0 evaluation version and run the attached VI.
Please let me know if this is not what you are trying to do.
Sincerely,
Feroz

How do I get the Adobe PDF navigation bar to automatically appear at the top of my screen again instead of when I move my mouse?

Before I upgraded my computer to Windows 7 and updated Firefox to the latest version, when I opened a PDF document online, the PDF navigation/menu bar would automatically appear at the top of the screen. Now it only appears at the bottom in a blue bar when I move my mouse around.

cor-el, thanks for the tip. While I certainly scoured Adobe's preference settings to look for something relating to that exact thing, I never went to their help site until I got your post. I found out that the floating toolbar appears because the PDF opens in'' Read Mode'', which you can turn off for all future documents by doing this:
* Quit your internet browser
* Launch Acrobat (or Reader)
* Choose Edit>Preferences
* Click on the Internet category on the left
* Deselect “Display in Read Mode by default”
* Click the OK button.
* Relaunch Acrobat
Something important to note, if you have both Adobe Acrobat and Adobe Reader, you need to do the above in both programs (same steps).

How to add a scroll bar within a view window ?I want to display x and y axis outside the scoll window and keep those axis static and move the graph within scroll area

how to add a scroll bar within a view window ?I want to display x and y axis outside the scoll window and keep those axis static and move the graph within scroll area
ananya

Hey Ananya,
I believe what you want to do is possible, but it will not be
easy. If you want to add a scroll bar that will scroll the graph
back and forth but keep the axis set, you would want to add a
horizontal or vertical scrollbar. Then you would create an event
handler for the scroll event. You would have to manually plot
different data within this scroll event. Unfortunately, there is
not really a built in way to do this with the Measurement Studio plot
control.

How could I possibly remove the default picture in the picture control?

I've been using the picture control and a bit of code to create a zoom effect on a picture. It all works great however I get a labview picture when the Vi is first loaded. I'm trying to get a blank area instead cause it doesn't look really tidy!
I've attached a picture and my code.
Thanks for your help
Solved!

Picture Zoom.vi ‏100 KB

The image is configured to be the default value of "Picture". In other words: you have to get rid of the default. You can do this by either:
a) Delete "Picture" and create it again. Disadvantage: You have to recreate all property nodes connected to this control.
b) Load an empty picture and then select "Data Operations >> Make Current Value Default".
hope this helps,

I haven't used the OpenGL CVI addition for years, but IIRC there is (was?)
no callback associated to it. Meaning that some actions are defined within
the OpenGL control, such as rotation/zoom, but that's it.
