How to stop the Dialog from being dragged

I was hoping that someone could tell me when calling a Dialog from Jframe, a how to stop the Dialog from being dragged
while a dialog is showing.
When it is visible I can still click and drag the Dialog
I want to set it so you can not drag it until the dialog has be closed.

If you don't have access to the parent frame, a "hack" that usually works:
Frame frame = Frame.getFrames()[0];
if (null != frame && frame instanceof JFrame){
JFrame jf = (JFrame)frame;
JDialog jd = new JDialog(jf, "title");
... code here ...
As each JFrame (or Frame) is opened, its stored in the array of Frames that you can get. Same thing with Dialog.getDialogs(). Almost always, at least so far for me I've never had this problem, the [0] index is the main window opened, or the parent/top frame. I'd put the check in there to be safe and make sure its a JFrame and usually you'll only have the one JFrame.

How can I stop the cursor from being dragged outside the bounds of an intensity graph in LV 7.1?

Currently, an intensity graph cursor can be dragged outside the graph bounds, and the cursor position continues to change as if the graph had no bounds.

You can maintain the cursor (and the graph scales...) between defined boundaries programmatically, using an attribute node. Not a very elegant solution, since there is some quivering. See the example.vi.
Of course, if the user need to modify the scales (zoom in/out...), there will be some additional work ! :-)
Hope this help.

How to stop the Calendar from editing your input?

How to stop the Calendar from editing your input?

I am constantly finding that Calendar Version 8.0 thinks it knows what I want to type but it incorrectly takes numbers and days and times out of my input and changes my appointments. I hate this new supposedly "smart" feature. Even when I edit my event correctly a second or third time it rewrites my input incorrectly again. I have to use my iPhone to override the annoying editing on my mac. I am ready to find a new calendar program unless Apple allows users to input what they want without their information being incorrectly edited.

How to stop an idoc from being processed further

Hi Experts,
I have a requirement where i have to stop the idoc from being processed in an user exit.
I have to stop the idoc and give a suitable status message over there.
It would be highly helpful if anybody tells me how to stop the idoc abruptly and giv the status messsage.
Thanks in advance.
Praveen.

Hi,
Check the below link

You need to find aproper EXIT.
The avaliable options for you in the exit is
IDOC_DATA
Now if i pick the segment having shiped qty from the data record and check the same with the delivery qty your objective is half done.
When the condition fails you need to update the IDOC with Error 51 saying that this is not possible .
for that you need to bring your logic as
LOOP AT IDOC_CONTROL.
PERFORM LOGIC...
ENDLOOP.
FOR LOGIC .
All the criteria and then update the status of the IDOC then error is generated and updated to the IDOc.
PERFORM updatestatusidoc.
endform logic.
like this in
form updatestatusidoc.
IF subrc = 0 .
t_idoc_status-docnum = f_idoc_contrl-docnum.
t_idoc_status-status = c_idoc_status_ok.
t_idoc_status-msgty = 'S'. -
>denotes success
t_idoc_status-msgid = 'ZXXX'.
t_idoc_status-msgno = '000'. "
t_idoc_status-msgv1 = itab-field.
APPEND t_idoc_status.
ELSEIF subrc = 1.
t_idoc_status-docnum = f_idoc_contrl-docnum.
t_idoc_status-status = c_idoc_status_error.
t_idoc_status-msgty = 'E'. "denotes --->error
t_idoc_status-msgid = 'ZXXX'.
t_idoc_status-msgno = '001'. "
t_idoc_status-msgv1 = itab-field.
APPEND t_idoc_status.
endif.
endform.
this has to be done to make the idoc to trigger error mode.

How to stop volume icon from being displayed randomly

How to stop volume icon from being displayed randomly

Thanks for the quick response.
I have a number of slides which act as a training module. The quiz follows this. All the answers to the quiz are in the module slides. I'd like the user to be able to see which questions they're failing on, but not be shown the answers, as, if they are failing the quiz, the whole module needs to be reviewed and the test retaken.
If this isn't possible, I'll probably just remove the review option, thereby meaning my retake button can stay, and the user can just go back and re-read the module slides to learn the answers.
Thanks

How to stop the users from changing User Profile

Hai,
It is not possible to restrict SU3 to display, because it has only S_TCODE has the authorization object.
If you really want to restrict users from changing their profile you have to remove the SU3 access and give SU1 or SU2 which gives access only to Personnel details and Parameters.
Hope this helps.

How to stop the dock from showing all hidden images when hiding then showing applications

How to stop the dock from showing all hidden images when hiding then showing applications

It's not really something to snap a screen shot of. I believe it would need to be a video clip. For instance, when I am working on multiple images in Photoshop, I often need many images open at the same time, but I only have one image viewable and active. The hero image is active on screen while I hide the other images in the dock by hitting the yellow - button on the images. Then I "Hide" Photoshop to do something in the Finder. When I go back to Photoshop, every image that is hidden in the dock will pop open again in the active window, not just the image I was currently working on. I want these images to stay in the dock until I need them, no matter how many times I Hide the Show Photoshop.

How to stop an email from being sent after I hit send?

How can I immediately stop an email from being sent after clicking "send"?
I can't seem to find any info on this. I am assuming that it is impossible. Correct?

When sending the emails with larger attachments that take a little time to actually upload and get out, you can open the activity viewer by pressing command-0 (or is it command-o?--)--it may also be under the window menu at the top--I'm not at my Mac right now to check. The activity viewer has a stop button on it. After you stop it, you should be able to either delete the email from the outgoing mail folder or drag that email to another folder, such as the drafts folder. I've done this a few times without a problem.

Anyone know how to stop the slideshow from looping?

Does anyone know which file to edit in order to stop the slideshow from looping? Where the code would be or, what code to add.
I am not aware of a setting from within iweb itself.
I assumed it was the slideshow.js file but I didn't find anything in there.
Such as a loop "true"
HELP

That worked great.
I assume what we are doing is copying and editing the
.mac slideshow file,
and then pointing to it's location in the folder. How
Yes, that's exactly it.
did you know what the code would be? I guess you must
be very Java savy, because it definetly wasn't an
obvious one.
It took me two days to reverse engineered dot mac slideshow
Is there a way to get the slideshow window to close
after it's finished? What I get is a freeze frame on
the last photo of the show.
I know you gonna ask that yes, change the added line in slideshow.js to this:
if (count == ((imgs.length) - 1)) { this.pause(); setTimeout("window.close()", 5000); }; // close window after 5 sec, change 5000 to whatever you like.
