How can I create a "print" button that will check the required fields before printing?

I have a form that is almost ready to be published. There are a few required fields to fill out. I have a Setup button print and check the required fields using this JavaScript:

var emptyFields = [];

for (var i = 0; i < this.numFields; i ++) {}

var f = this.getField (this.getNthFieldName (i));

If (f.type! = "button" & & f.required ") {}

If ((f.type=="text" & & f.value== "") |) (f.type=="checkbox" & & f.value=="Off")) emptyFields.push (f.name);

}

}

If (emptyFields.length > 0) {}

App.Alert ("error! ("You must fill in the following fields: \n" + emptyFields.join ("\n"));

}

Its form current you can click on the button and the required fields, the error message, but it still shows the form. Is there to allow printing not until all required fields are filled? I work in Adobe Acrobat X Pro.

Thank you!

In the end, use this:

If {(emptyFields.length>0)}

App.Alert ("error! ("You must fill in the following fields: \n" + emptyFields.join ("\n"));

} {This}

This.Print ();

}

  • How can I create a new Style that can be applied to an object?

    To the active menu there is a tab called "Styles".  My question is how can I create a new Style that I can apply to an object?  A link to a tutorial or something like that would be helpful, because I can't find anything!    Thanks in advance for helping me eliminate this frustration!

    What I want to do is create a style library, which are basically photos of different Woods.

    There are two approaches you can try.

    Clipping paths

    1. draw the shape of the part as a closed path.

    2 position the wood grain image above or below the shape where you want it positioned.

    3. cut

    4. Select the closed path.

    5. glue on the inside.

    See: Using FreeHand MX > content > work with objects > working with clipping paths

    Fillings in mosaic

    1. use the autotrace to vectorize the image of wood fiber, using many colors.

    Using FreeHand MX > content > work of imported using the > Tracing bitmaps > image vectorization

    2. the group the paths (but not the picture) and create a tiled fill,

    The less you have to run all the time, most things you want to run will perform:

    Use Autoruns to understand this all starts when your computer's / when you log in.  Look for whatever it is you do not know using Google (or ask here.)  You can hopefully figure out if there are things from when your computer does (or connect) you don't not need and then configure them (through their own built-in mechanisms is the preferred method) so they do not - start using your resources without reason.

    You can download and use Process Explorer to see exactly what is taking your time processor/CPU and memory.  This can help you to identify applications that you might want to consider alternatives for and get rid of all together.

  • How can I design a custom button that has three lines of text in the button itself?

    A matter of design, which is a good implementation of the following? I need to create a custom button that looks like:

     -----------
    | Header    |
    | Subheader |
    | Text      |
     -----------
    

    I know that I can not add a VerticalFieldManager or add any field of a ButtonField, but if I create a custom, button how I would create three lines of text similar to having three LabelFields lined up in a VerticalFieldManager?

    Thank you.

    You can create a focusable multiline field label creation with the bit style FOCUSABLE and with newline characters in its text. It is possible to work a bit like a button field (substitute navigationClick / navigationUnclick to perform the action or, better yet, to call fieldChangeNotify so that you can plug into the field with a FieldChangeListener).

    Use RichTextField rather than LabelField if you want to play with fonts (say, "BOLD" underlined header; italic subheader; normal text).

    If you want rounded corners and other effects, override the paintBackground method or painting of the field (don't forget to call the super.paint, if you go with the latter).

    That being said - that there is no single best design, so feel free to browse the forums (research of "multiline" or "multiline" yields quite a few results) and come up with your own ideas.

  • How can I create VI with inputs that run immediately when the update?

    I'm using LabView for controlling stepper motors. I would create a VI with a front panel that has 4 arrows, 2 per engine. My goal is to be able to run the VI and then press a button to move the engine.

    I created separate VI for each funcition of engines - one vi to set current operations, to determine the current travel, another to move up by a certain amount and so on. Work of these vi and I can move and adjust engines, but only by running separate VI.

    How can I combine them into a single VI and make them run to the pressure of a button or the change of a property? An example would be to establish a new current holding company and place the operation current vi run immediately and send the order to the engine. Then continue to press the arrow keys without having to hit 'run' on an another vi.

    Thank you very much

    I don't know how to create this type of form online that include as this fields

    If someone has answered this question, it would be appreciated

    Thank you

    Nehr

    You just need to make the field. Another is a box and you can have a text corresponding to this field.

    You can style that you need and if you know javascript you can take a step further and show that this field when you check the 'other '.

    As a note: If you make the options that you want only a single option, you must use radio not check boxes for the fields.

  • How can I create a new layer that is a gradient?

    Hi, I'm very new to scripting photoshop and have some difficulty.

    I am looking for a way to take a picture I have and configure it to have a gradient opacity as he approaches middle, my thought on how to do was simply to create a layer that is a gradient from the upper left to lower right and secure then as a vector mask.

    Any ideas on how I could create this gradient layer of script or a better method to do this opacity gradient?

    Thanks in advance,

  • How can I make a button that will move the mail that I consult to a specific folder?

    I'm moving to Eudora, where I had several buttons that I had added to top to move e-mails in specific folders, such as invoices, orders, Support, etc. I see that I can customize the top bar in Thunderbird, but I can't seem to find a way to make buttons to automate the movement of e-mails in specific folders. Is there a way to do them in this program?

    I'll assume you are using Microsoft Outlook.

    For 2007, go to the Menu bar at the top, tools-> Options-> Mail Format tab at the top-> Signatures and then create your signature you want.

    For 2003, it is almost the same process.
