Forcing a JWindow to pack/validate and resize

Hi,
I'm using a JWindow with some JComponents in it and I'm trying to set the font of this window and all of its components. After setFont() (which works) I want the JWindow to resize because the label sizes etc. changed with the new font.
I tried JWindow's pack() and validate() methods but the window keeps its old now incorrect size.
What can I do to recalculate the layout and to resize the window correctly?
Thanks
Frank

Your example works for me, too. But when I try (nearly) the same in my application
System.out.println(myPanel);
System.out.println(myWindow);
dialog.setFont(font);
myWindow.pack();
System.out.println(myPanel);
System.out.println(myWindow);
I get the following results:
JPanel[,0,0,113x149,invalid,hidden,layout=com.jgoodies.forms.layout.FormLayout,alignmentX=null,alignmentY=null,border=javax.swing.border.EtchedBorder@1be1041,flags=9,maximumSize=,minimumSize=,preferredSize=]
JWindow[win0,0,0,113x149,invalid,hidden,layout=java.awt.BorderLayout,rootPaneCheckingEnabled=true]
JPanel[,0,0,113x149,invalid,hidden,layout=com.jgoodies.forms.layout.FormLayout,alignmentX=null,alignmentY=null,border=javax.swing.border.EtchedBorder@1be1041,flags=9,maximumSize=,minimumSize=,preferredSize=]
JWindow[win0,0,0,0x-1,hidden,layout=java.awt.BorderLayout,rootPaneCheckingEnabled=true]
The panel seems to resized but in strange way. When I make it visible it has the old size.
myPanel is a panel in myWindow. I use myPanel from myWindow to show it in the ModalLayer of a dialog so one of myWindows panels has been added to the modal layer of dialog.

After moving and resizing control, some controls don't redraw properly as the cursor passes over them.

I have a top-level VI with three panes (two splitters). One of the panes contains nested tab controls. One of the tab pages contains six XY-graphs, a table and some decorations.
I use a subVI to resize and relocate the tabs and contained controls. All this is working fine, and everything looks fine after the resizing is complete.
The problem is when the cursor passes over certain controls (the chart legends and the table column headers for example), they redraw with gray boxes. The problem only occurs after enlarging the window from its minimum size. It goes away if the window is resized back down to minimum.
Anything that causes the window to redraw, like another resize or minimize/restore, properly refreshes the screen.
Has anyone seen this problem, and have a workaround?
The problem exists in development environment or built in LV 9.01 or LV 2010.
Thanks!

Thanks again for taking a look at my problem.
force redraw - This is apparently only available in LV2010. I did give at a try, but it did not prevent the problem, nor did it correct the problem once the gray boxes appeared.
disable updates (on a graph) - This apparently only applies to 3-D graphs, which is not what I am using in this case.
disable front panel updates - I tried disabling updates before moving/resizing the front panel controls, then re-enabling updates afterwards. The problem is exactly the same as before. Once the move/resize is complete, passing the mouse over the table column headers or the graph plot legend results in the gray boxes.
I would appreciate any other suggestions you may have.
Again... the problem is not that the moving and resizing don't work. They work fine. But once the resizing is complete, passing the mouse over the legend or table column headers causes gray boxes to appear.
Thanks!

ORADC problem on Windows 2000 with Service pack 1 and service pack 2

Hi,
I have a VB application running on NT4.0 workstations. It uses
ORADC control to talk to ORACLE 7.3 When I load it on Windows
2000 with service pack 1 or service pack 2, I encounter some
problems.
The ORADC control is used in most of the VB forms and the
Refresh method of the ORADC conrol is used to refresh the APEX
TRUE DBGRID PRO control. When this action is executed, I receive
a run time error
"Method Refresh of object '_DORADC' failed Err#: -2147417848
It works fine when no service pack is applied on Win2K.
Can anyone tell me what's going on?
Thanks

What is the best way to move and resize layers?

When I click on a layer to move and resize it in Elements 8 in Windows 7, it disappears. After I go to Edit/Undo, it reappears. What should I do?

I have PSEv.8 and Windows 7, and the Editor works like a charm for me.
Try the following:
Open picture 1, duplicate the background layer.
Open picture 2, make a selection of something in the picture with one of the selection tools, and then go to Edit>copy. This puts the selection on the clipboard.
Go back to to picture 1, go to Edit>paste, and the selection will be on its own layer
Use the move tool to position and resize the selection.
The middle layer can be dragged to the top. Here, this process will obscure visibility of Layer 1, but you can drag the layer structure back, of course.

I opened a picture of the house on the lake, copied/pasted the "Slick Rock Divide" sign as per above. The layer structure is represented in the print screen.
You should note that it is best if the resolution of the picture files is the same, or close to it.

Photoshop CC: Have a template that I moved image into. Image is too small. How do I resize the image while in the template? Or must I go to original image file and resize there again and again until I get the right fit?

I have a template that I am able to plug different pictures into at different times. The problem is that when I plug an image into that template, I find that the image is either too big or too small. Is there a way to plug the image into the template and resize the image (and not the template itself) OR will I have to go to the file with the original image and resize it there and then try to plug it in to the template to see if it fits------and if it does not fit, go back to the original file with the image and resize it again and see if that fits---and so on and so on...........? I have tried the" image size" option but it's hit or miss------mostly miss!
Thanks!

Read up on Smart Objects. It looks like you have no idea as to how to create and use them.
Jut create a Smart Object from the layer containing whatever it image it is that you are "plugging into your template". But you do need to learn the application at its most basic levels.
Photoshop is a professional level application that makes no apologies for its very long and steep learning curve. You cannot learn Photoshop in a forum, one question at a time.
Or is it possible that you don't even have Photoshop proper but the stripped-down Photoshop Elements?"
If the latter is the case, you're in the wrong forum. This is not the Elements forum.
Here's the link to the forum you would want if you're working in Elements.:

If you do have Photoshop proper, please provide the exact version number of that application and of your OS.

How to enable Validate and Export in FDM task

Hi everyone
I am working with setting up an FDM Task to Import, Validate and Export data to HFM.
The Task is able to import data to FDM, but I cannot make the process start the Validate and Export functions. If I do the process manually, then data is imported to HFM succesfully.

Found the solution.
The variable lngProcessLevel should be set to "12" to execute the full Import, Validate and Export.

Firefox 4 Beta has problem when printing shipping pages from Amazon Marketplace, it shows and prints strange symbols instead of the packing slip and the label. Do you have any idea why is that?

Well, I installed it 2 days ago and yesterday when I tried to print a packing slip and a label for Amazon customers it printed so many strange symbols that were nothing like what they are supposed to be, not even close. When I printed it with another browser it was all fine, so it is obviously a problem of the new version of my favorite browser. Probably something with the encoding, but since I'm not a computer geek, I cannot give more info. :(

'''If you go the the menu and click "Print Preview" then it will show normally, and will print correctly from there. You must do it this way the first time you try to print though, if you try to print (using the print command) and it is messed up, then it shows it messed up in the preview. It's not a cure, but works for now until this bug is fixed.'''

Upload and Resize Image not inserting filename in database

I have a form that I created using the insert record form wizard. One of the fields is a file field and my form enctype is set to multipart/form-data. I then used the upload and resize image behavior and set the parameters. When testing the form the file uploads to the correct directory but no entry is made into the database for that particular field. The other fields are entered into the database just fine. If it helps, here is the code generated before the tag:
 
 <?php require_once('../../Connections/test.php'); ?>
 <?php // Load the common classes require_once('../../includes/common/KT_common.php'); // Load the tNG classes require_once('../../includes/tng/tNG.inc.php'); // Make a transaction dispatcher instance $tNGs = new tNG_dispatcher("../../"); // Make unified connection variable $conn_test = new KT_connection($test, $database_test); // Start trigger $formValidation = new tNG_FormValidation(); $tNGs->prepareValidation($formValidation); // End trigger //start Trigger_ImageUpload trigger //remove this line if you want to edit the code by hand function Trigger_ImageUpload(&$tNG) { $uploadObj = new tNG_ImageUpload($tNG); $uploadObj->setFormFieldName("picture"); $uploadObj->setDbFieldName("picture"); $uploadObj->setFolder("../images/"); $uploadObj->setResize("true", 120, 0); $uploadObj->setMaxSize(1500); $uploadObj->setAllowedExtensions("gif, jpg, jpe, jpeg, png, bmp"); $uploadObj->setRename("auto"); return $uploadObj->Execute(); } //end Trigger_ImageUpload trigger // Make an insert transaction instance $ins_team = new tNG_insert($conn_test); $tNGs->addTransaction($ins_team); // Register triggers $ins_team->registerTrigger("STARTER", "Trigger_Default_Starter", 1, "POST", "KT_Insert1"); $ins_team->registerTrigger("BEFORE", "Trigger_Default_FormValidation", 10, $formValidation); $ins_team->registerTrigger("END", "Trigger_Default_Redirect", 99, "../team.php"); $ins_team->registerTrigger("AFTER", "Trigger_ImageUpload", 97); // Add columns $ins_team->setTable("team"); $ins_team->addColumn("id", "NUMERIC_TYPE", "POST", "id"); $ins_team->addColumn("sort", "NUMERIC_TYPE", "POST", "sort"); $ins_team->addColumn("name", "STRING_TYPE", "POST", "name"); $ins_team->addColumn("title", "STRING_TYPE", "POST", "title"); $ins_team->addColumn("description", "STRING_TYPE", "POST", "description"); $ins_team->addColumn("picture", "FILE_TYPE", "FILES", "picture"); $ins_team->setPrimaryKey("id", "NUMERIC_TYPE"); // Execute all the registered transactions $tNGs->executeTransactions(); // Get the transaction recordset $rsteam = $tNGs->getRecordset("team"); $row_rsteam = mysql_fetch_assoc($rsteam); $totalRows_rsteam = mysql_num_rows($rsteam); ?>

If the reason is about memory, warning message should be happened when upload the image, because "show thumbnail" means resize at second time, how come you failed to resize the picture that system let it upload succeed at the first time by the same resize process?
upload procedure
a.jpg: 2722x1814, 1.2mb
upload condition: fixed width 330px, 1.5mb
"upload and resize" a.jpg -> file upload -> "resize engine" -> passed (but not work and no warning message)
"show thumbnail" a.jpg -> "resize engine" -> failed (not enough memory)
it doesn't make sense.
and you miss an important key point, I upload the same picture myself, and resize work, so I said it happened at random, and that's why I am so worried.

Use of Java Swing +Applescript to move and resize Mac OS X windows using

Here is an interesting use of Java on Mac OS X and Applescript to
enable moving and resizing of windows using mouse and keyboard:
[MoveResize tool|http://code.google.com/p/sandipchitalesmacosxstuff/#Move_and_resize_windows_on_Mac_OS_X]
How it works:
The implementation uses Applescript to get the front most window and
it's bounds. It sends the bounds rectangle to a server implemented in
Java over a socket connection. The Java server takes the screen shot
of the full Desktop and uses it as the Image label (a JLabel with
ImageIcon) as the content pane of an undecorated JFrame which has the
same bounds as the Desktop. A JPanel with semitransparent background
and a dark rounded rectangular border is given the same bounds that
were received over the socket. This JPanel is added to the
PALETTE_LAYER of the JFrame's layered pane - which makes it appear
floating in front of the front window. A Mouse and a Key listener
added to the JPanel allow moving and resizing of the JPanel. When the
user types the ENTER key the JFrame is hidden and the new bounds of
the JPanel are sent back to the Applescript over the socket connection
which moves and resizes the front most window.
Enjoy!

Copy the /Home/Documents/ folder to the NAS drive. That drive needs to support AFP or you may run into filename problems and/or other file related problems due to filesystem differences.
Once the folder has been moved to the NAS select the folder on the NAS and CTRL- or RIGHT-click. Select Make Alias from the drop down menu. You should now have an alias named "Documents alias." On the Mac put the /Home/Documents/ folder in the Trash but don't delete it. Copy the alias file from the NAS to the /Home/ folder. Rename it to simply "Documents." Double-click on it to be sure it opens the folder on the NAS. If so you can empty the Trash. You're done.

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
If you are running 64-bit Windows and the above steps haven't helped try installing the version of iTunes that can be downloaded from this support document. iTunes 12.1 for Windows (64-bit — for older video cards)
If you still have no luck try reinstalling iTunes 12.0, links in the user tip.
