problem when you try to rename the images uploaded by using the value of the session

Hello

I have a form where 9 images are downloaded into thumbnail size and then stored in a file. What I m trying to do is to rename these vignettes of their original name for username_0, username_1, username_2 etc. for each of the 9 inches. The user name is the registration form on the same page. I created a session for the username variable and tries to use it to change the name of the image, while my pictures are for download and resize the rest as the original and not as the new number name of $ username_. I have pasted the code below, and would be very grateful for any help with this:

<? PHP session_start();

...................

Check that the form has been sent and this name is not empty and has no errors
If ($_POST & &! empty($_POST['directusername'])) {}
Set session variable
$_SESSION ['directusername'] = $_POST ['directusername'];
}
define a constant to the maximum download size
define ('MAX_FILE_SIZE', 5120000);
If (array_key_exists ('upload', $_POST)) {}
define constant for file transfer
define ('UPLOAD_DIR ',' J: / xampp/htdocs/propertypages/uploads /');
convert the maximum size in KB
$max = number_format (MAX_FILE_SIZE/1024, 1). ' KB ';
create an array of allowed MIME types
$permitted = array (' image/gif ',' image/jpeg ',' image/pjpeg ',' image/png');
foreach ($_FILES ['photo'] ['name'] as $number = > $file) {}
replace all the spaces in the file name with underscores
$file = str_replace (' ', '_', $file);
Start by assuming that the file is unacceptable
$sizeOK = false;
$typeOK = false;
Verify that the file is within the allowed size
If ($_FILES ['photo'] ['size'] [$number] > 0 & & $_FILES ['photo'] ['size'] [$number] < = MAX_FILE_SIZE) {}
$sizeOK = true;
}
Verify that the file is a permitted MIME type

Problems when you try to move the 3 stepper motors

Hello

I have problems when I Isaiah to compile a 3 stepper motors control program.

I have 3 steepest motors and controller (3 SMCP33 + SMCP33-EVA) nanotec.com, they also provide an example of Vi to control a motor that works successfully, but problems happen when I try to adapt the program to try to start the 3 Motors. The final application for this is going to be a Cartesian robot XYZ so finally I need to program coordinates to move the 3 Motors.

I am new to LabVIEW, so what I do is try to adapt the nanotec example to order 3 engine as follows.

-J' I assign each engine a different address, doing so that I can run each engine separately. But when I try to run 3 programs at the same time, they work but all moving them the engine (the first that has been run).

-If I try to make a sort of sub - VI is the same thing, only one motor is driven.

-Moreover, I get a warning when I try this, I have attached a screenshot of this.

I have attached the Vi and texture it to improve my description.

I woul be grateful if someona can help aport.

Kind regards.

Thanks for posting the original. By comparing the two screws immediately gives an indication of what might happen.

In the picture you posted you circled two places where you changed the address of the reader. In the Example.vi - Nanotec address of the player is connected to about 14 seats. So when you try to run the other engines in your modified program, the 12 places, you have not changed the address of the player are always preset to motor 1.

What you need to do is to divide the example VI in at least three parts. The first part initialization. The next part moves the engine. The last part ensures that the engine is stopped and made any required another stop. Each party becomse a separate Subvi. Each Subvi has the address of the reader as input. The initialization and shutdown parts are placed before and after a while loop. The movement parts are inside the loop. You can use three of each sub - VI for the three engines or a Subvi combined with subVIs move three to manage all three engines.

I can't say what approach might be better without knowing more about how you plan to order the engines - one at a time or all three at the same time, what kind of feedback is used, how management mistakes and other topics.

OfficeJet 6500 more e a-> HP - DQEX5.exe problem when you try to install the CD

I bought above mentioned printer.

REF: CN557A

SN: [personal information]

I use Windows XP

Follow the start-up procedure quick and everything worked well. I'm at the stage now where I had to put the CD, follow the configuration steps.

I deleted the old HP software (from my HP printer) previous first. Then I tried to install it and whenever I get an error after awhile, saying there is a problem with HP-DQEX5. EXE. He closes the Setup program.

I tried several times, but it does not work. Today, I deleted the first update HP (I think it was installed last night, when I was trying as well). Then started again, but without success.

I NOT connected the USB cable, as the manual says not to do so until the installation program tells me to do.

Could someone please try to help me?

I get very upset, frustrated and so on. Plug-and-play said. Care Yes, don't play yet. = o)

Thanking you in advance.

The old printer may have some components behind which can be erased using a normal life to left uninstall method. What printer model was your old printer?

Problem when you try to update the database

The problem I have is that whenever I try to change a certain element of customer information it always modifies a totally different number that has no meaning. in the database. For example, an island of customer id is 3 and I want to change it to 12, the number that indicates the database after you have clicked on update is 40430. I am at a loss and have no idea why he did such a thing. Here is the file change to make the changes accordingly.
= Edit file =.
<!-insert or update? ->
< cfset EditMode = IsDefined "(FORM. BusinessID") >

So you're saying that if you do a CFDUMP and CFABORT just before your update request then Form.IslandID is, for example, 4; but he actually wrote a number 5 digit to the database? Because it's all just ridiculous. Are you absolutely sure that you have not named two identical form fields? If you do this, CF will concatenate their values by commas that CFQuery will almost certainly do everything right in the database because it assumes that it is what you want.

Oh and read about CFQueryparam.

"Not enough memory is available to process your order" when you try to install the drivers

Recently, I have problems when you try to install the drivers for a USB mouse that I have. When I plug the mouse, it detects it and tries to install the software but it gives me an error saying he found the software but can't install it because "not enough memory is available to process your order."

I spent a bit of time, search tries to find a solution to this problem, and I tried a lot of things without success.

I tried the things:

-Manually installed the drivers. While I can install them, Windows does not recognize the drivers as being installed and the mouse still not working.

-The fix IRPStackSize. It was not in the registry, so I thought this might be the solution, but it does not solve my problem.

-Troubleshooting and repair of Windows Update. I had a memory leak problem with Windows Update, so I thought fix which would cure the problem. I was able to d/l an update that corrects this problem, but it does not solve the driver problem.

Anyone have any ideas on how to solve this problem? Thanks in advance.

Lightroom is not in the expected location that he thinks that the photos are in the photos.

This can happen because you have (perhaps accidentally) moved, renamed or deleted photos or folders containing them outside of Lightroom.

The solution is to use your operating system to find the new location of the photos. Take note of where they are. Then in Lightroom, you can reconnect to them through these instructions: Adobe Lightroom - find folders and files moved or missing

As an alternative, if the files were simply moved (and not renamed or deleted), you can use your operating system to move towards where Lightroom is expected to make them.

Portfolio crashes when you try to build the cover page of an image imported via Lightroom sync project.

The title says it all. While you can import images into a new project through Lightroom mobile sync when you try to create a cover image for the project, you can select one of the imported images, but when you try to apply the portfolio crashes. The only way to go beyond this stage is to import them separately a jpeg.
Another problem with imported via Lightroom photos mobile sync, it's that the display full screen obtained by double clicking on the image in the project is not centered on being right-justified display. There seems to be no way to change this behavior.
How to overcome those problems?

Just tried again this morning and guess what it worked perfectly. Only difference I can see is that Lightroom is running and who claims to be always sync when I had the problem and this morning when the problem went away Lightroom was off. Incidentally, if you want to report bugs that you must go to the portfolio help page and ask a question.

Hello
I use Lightroom 5.7.1 on a 'Late 2012 iMac' with Yosemite OS X.
I installed Yosemite first and then Lightroom 5.
After that I encountered the first problem (no preview images shown the import module when you try to import new images, the central part of the screen remains black, now shaded not extracted, nothing, no possible to import at all), I tried all possible changes to checkboxes and preference settings.
After reading dozens of Internet Forum articles on very similar problems seem to many other users, I even deleted all preference setting files in the OS X Finder (a recommendation that has been said to succeed), however, the problem remains.
Also, I completely deleted the software entirely from my iMac (including all the system and setting files), downloaded the latest version (5.7.1) Adobe, rebooted the system, installed new Lightroom, even restarted again, WITHOUT SUCCESS.
What could I do? As I can't work at all with Lightroom, I would be very happy to get any help on this issue.
Best regards
Thomas.
