Velocity Input Curve Drawing Bug

Hi,
I'm trying to scale the midi velocity input of my controller by drawing a curve. However, when I draw the curve in the "velocity input" window, my trackpad pointer is offset. That is, it doesn't select where I click. Highly annoying bug. Any ideas?
Thanks

Multiple velocity inputs in a sequence of blended moves

I used the template 'Sequence of Blended Vector Moves' in order to synchronize two different motions on two different axes. I am trying, however, to input two different velocity vectors (one for each axis move) and can't seem to find a good way to input both of them as the velocity input only accepts a single input.
Thanks!
Lauren

Hello laf3g,
Have a look at the attached LabVIEW VI. I duped the “Load
Velocity in RPM” VI and allowed for the velocity specification of each axis.
Give this a shot and modify accordingly. I hope this helps

Can I control a stepper motor by a time varying velocity input?

I want to control the motion of the stepper motor by a velocity input that looks something like a Sine wave.The velocity is changing as a function of time. Can I change the velocity of the motor at a prescribed time interval?
Thanks in advance
Kevin

Thanks for getting back to me on this. The controller card that I have is the PCI-7342 controller card. The time of a cycle is about seven minutes. I want to ramp the RPM of the motor from zero up to a max value then return it to zero and then go in the opposite direction . A graph of the RPM vs Time is attached.
I thought that I could input an array of velocities into a Load RPM VI and specify the time for each input.I have not been able to do this as of yet, because the load RPM VI will not take an array input.
All these inputs would be made in labview so they are inputs for the controller card. I was under the impression that the controller card generates the steps and direction from the data entered in labview and sends the step and direction impulses to the driver. Do I have the method of operation right?
Do you think this is possible?
Thanks again

Time varying velocity input for servo motor

I 'm running a PXI-8145RT CPU with a 7344 motion controller.I want to load a time varying velocity profile for my servo motor.How can I do this? The "load velocity" tile does not have an input for such a profile,but only for a maximum velocity that will be reached after a certain time.

Are you using the Motion Assistant or a programming language like LabVIEW? If you are using the motion assistant, you can do a contoured move with a Position-Velocity-Time Profile. I have never done this, but it sounds to be what you are looking for. This assumes that you have a controller that can do contoured moves.
Hope that this helps,

Pen Tool - Curve drawing under Object Lock

How do you draw a smoother curved line as described in this tutorial in Steps 6 and 7?
http://design.tutsplus.com/articles/create-a-glowing-neon-sign-using-the-appearance-palett e--vector-3791

Thank you - As it turns out, I was using the tutorial here as a guide http://design.tutsplus.com/articles/create-a-glowing-neon-sign-using-the-appearance-palett e--vector-3791
I was trying to use Steps 6, 7, and 8 to draw lines with the Pen tool that traced the interior of letters to generate a neon sign effect to keep applying new strokes to build up the glowing effect.
I am having difficulty recreating smooth lines inside the trace of the letters – my lines look choppy and not at all like the tutorial suggests.
I was using the Appearance Palette, which stressed using simple paths that can be turned into vector artwork simply by using multiple fills and effects. The approach was to use the approach outlined to avoid having to use complicated Bezier curves or stacking multiple vector shapes on top of one another.

Lumia 900 Screen Draw bug

Found an interesting bug on a few lumia 900's (i have tried it on 4 and all show it) that may affect certain games, especially Harbor Master for me since it involved drawing lines to the screen edge.
The problem is that if you draw one straight line from the left edge of the screen to the right edge (or the other way around), the end of the right edge (about 1 cm wide) doesnt acknowledge the line drawing unless the line is drawn very slowly.
To reproduce the bug, open the nokia diagnostic tools and run the 'Touch' test. To get the diagnostics tool if you dont, just dial ##634# using the touchpad.
Draw a line fro the left edge to the right edge quickly and you will see what i mean. Or from the right to left. The same thing happens if drawn from top to bottom.

1. I notice it is when I go to unlick my phone there is a noticable lag. When I pres the first digit of the PIN it doesn't register until after I have tapped the second characetr of the PIN.
2a. When the phone is charging it is VERY laggy. This is especaiily noticable when scrolling the start screen. Instead of the buttery smooth scrolling it is very choppy.
2b. I have also noticed the slow response when plugging/unplugging the phone. Just today after I unplugged my phone it toook several minutes for it to acknowledge it had been unplugged. As long as that occurs I see the issua of 2a (choppy scrolling, etc.) as is if it were still plugged in.
3. The entire device seems to momentarily freeze when the brightness automatically adjusts.
4. At times the typing in any text box (email, text meassage, etc.) seems to fall behind. It is most noticable when first starting the message (maybe the brightness is changing?).
I have those EXACT Same issues too. Will also not that the brightness (when on auto) is SLOW to adjust to the lightting enviroment. The biggest pain is #1 - as i usually have to enter my PIN in twice..
I love my purple screen, 1/2 day battery, sketchy touch screen and $800 price tag - I call it my Lumia 900

Multiple Variable Inputs in Query- Bug in Bex??

Hi,
I have Multiple Variables I am using in a Query. After I Input a Value Range to suppose a date field, and then for another variable I use the drilldown box to select an Input for this variable, The First Value of My date field dissappears but the other value in the range still remains. Only If i make this Variable Mandatory with Interval, it does not dissapear.
This is not only applicable to Date Variable but also for Serail nbr, etc where I enter a range for the variable and when I input a second variable using the drilldown box feature, the first value dissapears from the earlier varaible input.
Please advice.
Thanks and Regards
Andy.

Hi Bhanu,
Suppose I enter a range for
Serial Nbr variable as CC22* and CC35*
and then use drilldown feature to Input another variable Prdtn year (2004).
The first value for Serial nbr (CC22*) dissapears..
Hope this helps...Or I can explain more..
Thanks ANdy

BI Beans: drawing bug (crosstab)

There is a small problem when drawing crosstab's column header with auto-wrapping (see http://softwarer.nm.ru/bi_beans_problem.gif) for screenshot.
There are really two problems. First: when drawing a multiline text, it's second line does not indented properly (I suppose it should be left-aligned with first line). Second: when cell width is near of longest word width, it draws an additional empty line at the top of the cell (see on the bottom of screenshot).

We will address this issue asap. Thanks

Graphics re-draw bug in main Hyperdraw window?

Hi there,
I'm struggling to explain this one clearly, but I'll give it a go....:
When moving or copying a multiple-selection of events in Hyperdraw (e.g. copying 2 bars of pitchbend), the ghost-outlines created to show the potential new position of the events (before you let go of the mouse) get repeatedly drawn across the grid (as you move the mouse around) without the 'old' ghost-outlines clearing, thus making it very tricky to know where you're dropping the copied events to because the entire grid-line is filled with ghostlines....
Can anyone else replicate this problem? It looks like a bug from where I'm sitting....
Thanks,
Jason

Curves adjustment Bug

I have PS 6.0.1. yes I know its an old version but it does everything i require so I have no need for upgrade.
One of the main function i use it for is adjusting curves. recently I have noticed when i open a jpg and select adjustment/curves. Photoshop automatically selects the eyedropper tool and the curves window is NOT displayed. When i attempt to do anything i get the windows error bell/noise. The only way i can carry on is by selecting escape on my keyboard.
This also happens if i attempt to add a curves adjustment layer. The eyedropper tool becomes selected and no curve adjustment window is displayed.
I couldn't find anything on google about this issue. Previously the curves adjustments worked fine for me and ive tried several different rgb images. I also tried resetting all tools.
Has anyone got any ideas what could be causing this.

Reset your prefs by holding out ctrl-alt-shift during startup. More than
likely the curves window is remembering its location, and it's off screen.
Nothing wrong with PS6. I keep it installed because it was the last
version before activation was instituted. This way, I am guaranteed some
Photoshop functionality in the event of an activation mishap when I do not
have access to the Internet.

Linear Fit Weight Input Modifying Control Input - Impossible? Bug?

I was having some strange data array issues with a program I was debugging and ended up distilling the issue to this. When "Linear Fit" is called twice it modifies the weight input array passed to it. Sounds crazy; but its true. I've been able reproduce this with a simple vi that I've attached.
The terrible thing is that if the weight array input is a control; its values will be modifed after calling Linear Fit. And if you've branched that wire and used its values for some other part of your program; the values on that wire will also change.
I'm using LV 8.5.1
I'd appreciate it if someone could verify this is happening on their machine. I'm too delirious from beating my head against the wall after tracking this down.

You can also patch the problem by inserting an "always copy" primitive right before the linear fit. See attached.

Hyper Draw Bug or Operator Bug?

When using HyperDraw, in an Arrange or Matrix Window, I try to Shift-Select (by shift-clicking or rubber banding) a non-contiguous number of nodes, I will mostly get all nodes in between as well but sometimes shift-clicking makes no selection at all.
This is quite different from the description in the manual.
Maybe I have overlooked some setting elsewhere preventing what I need to do? I hope so.
Any suggestions?
I am using LP7.2.3.
Thanks very much,
Marius

Aarrgghh. I know part of the problem is that I don't quite grok Aperture's model yet. But, still, something is not right.
I had created a new project called "Trips". In that project I created an album. If I selected photos from the "All Photos" smart album, I could put them in that album in that other project. But the photos still weren't in that other project. Just the album. This seems wrong, but I'm not sure.
So, instead of creating a project called Trips, I created a top-level folder. In that, I created an album for my one trip. Once again, I could select photos from another project. When I dragged them to the new album, I got a green "+". But when I dropped them, nothing happened. But, if I drag them from "All Photos" it works.
That can't be right. If I can put photos from any project into an album, I should be able to do it from anywhere. If I can't, I shouldn't be able to do it from "All Photos." If anyone knows which is right, let me know. Also, if anyone knows how to file a bug, let me know -- I will file this one with a good use case description.
Thanks,
tim

Screen draw bugs?

Has anybody experienced these bugs in Dreamweaver CSS for the
Macintosh:
a.) When you have multiple windows open at once and you "step
back" from them in Expose to view them all at once, some or all of
them display as blank white sheets.
b.) When you drag a window to reposition it on your screen,
it displays in both locations until you click on it in its new
location.
c.) Sometimes when you mousedown + drag your cursor over a
bit of text to highlight it, the highlighting fails to show on the
screen, although the text you have chosen is in fact selected and
can be cut, copied, etc.
d.) Suddenly and inexplicably a page of text will start
displaying in a different font than the one you chose, and you have
to quit and reopen the document to get the font back.
I'm curious to know if I am unique in experiencing these
problems, or whether they are common. I suspect the latter, since I
am using a Mac Pro that is pretty much out-of-box, with the
original graphics card and so forth. Or is there some other
software I could have on my computer that could possibly interfere
with DW working properly.

Pulling up another page based on input in a form

I have a simple website with a form & one field that is
for a drawing number. I want the user to input the drawing number
& pull the drawing up based on the drawing number after the
user hits "submit". I've tried several things & this should be
pretty easy.
Here is what I'm after: Enter Drawing NUmber:_______________
Once the form is submitted, the drawing number entered is
pulled up from another directory. I can attach to the directory and
pull the file up if I just use a hyperlink, but I don't want to use
a jumpmenu (because I don't want to SHOW the user the choices, I
want the user to input the drawing number).

hi,
you have to create a sub class of CL_UPWB_BSP_APPL i.e(create a class whose super class is CL_UPWB_BSP_APPL).
since the BSP Event Handlers are implemented in it
you can change accordingly.
check this for enhancement for web interface:
