Nitpicking newbie frustrations

Greetings,

I did some C, Javascript, VB, Python programming. A bit rusty now, but I intend to develop a few fairly simple BB apps. Got started with the installation of Eclipse (the all-in-one download).

I have a problem that is getting me down. I made Hello world, and a couple of tutorial relies on the web: Tip Calculator, connect dialog box. They work. The basics of the IDE are understandable.

NOW, I'm following a tutorial that uses 4 classes and when I try to launch it, I get only "My Title" on the screen of the Simulator, and an eclipse warning that the main method in the Application class is not invoked:

WARNING! : 'org.mobiledev.bb.fallingFruits.FFmainApp.app (String [])' method not invoked.

I spent hours and hours with Google searches, and/or implemented subtle changes in my code or structure of package and names, try to resolve it.

BTW, I don't understand why most names package that saw him begin with "com" but, I don't think that's the key. The tutorial that I work through them has starting with "org."

http://mobile-development.org/index.php/BlackBerry/introduction-to-BlackBerry-game-development-part-...

Here is my current code of the Main App:

package org.mobiledev.bb.fallingFruits;
Import net.rim.device.api.ui.UiApplication;
SerializableAttribute public class FFmainApp extends UiApplication {}
          
public FFmainApp() {}
Utility.pushScreen (new StartScreen());
}
          
public static void app (String [] args) {}
FFmainApp app = new FFmainApp();
app.enterEventDispatcher ();
}
}

I had an another weird prob. I was in one of the tutorials to add a .png image. Apparently never, even if I took pains to make it good:

BitmapField bitmapField;
public UiFunMainScreen() {}
Bitmap logoBitmap = Bitmap.getBitmapResource("res/img/self_portrait_tiny.png");
bitmapField = new BitmapField (logoBitmap, Field.FIELD_HCENTER);
Add (bitmapField);
...

Please help me clear up. I hope that my problems will look pretty stupid, once identified.

Thank you!

I think I know what is happening with Eclipse... who have now implemented a new workspace and a project name, and the package...

Eclipse automatically creates a package named mypackage. I've been following tutorials and create a package as directed, usually starting with com.something.something. But the original mypackage is still there, which, I think, was for a good reason.

When I did a tutorial with the name of the package from org.something.something, it appeared listed alphabetically AFTER mypackage. Apparently, the two packages are running, and the primary method in which runs first, in alphabetical order, is the one that is active and visible, while the other is not.

Then, get rid of mypackage and all is well. Right? I hope that's not there for some esoteric reason, I still don't understand!

So, it works on the following problem...

  • Lag - lost newbie desperate and a bit frustrated

    So I just download Premiere Pro the first time yesterday for a school project. This is my first time using something more advanced than Windows Movie Maker, so I was watching YouTube tutorials on how to use everything.

    I feel really terrible lag with audio and video and I can't understand how to fix it. I saw another thread to it a few years ago, where some suggested making audio, and I tried, but nothing improved.

    Since I'm still new to this any suggestions of solutions would be appreciated, especially if explained in a way thorough (and honestly pretty dumbed-down), because I'm totally lost, but I'm trying to power through.

    I don't know if this is essential information, but I'm working on an HP laptop.

    Any help is appreciated great. Thank you!

    Your computer is average to low-power to run Premiere Pro.

    Please do scroll down and read the articles here:

    I suggest that you try to use Premiere Elements instead, but even that can be a struggle:

  • Newbie questions

    Greetings

    After nearly 40 years, using Windows, I ordered an iMac 27 "(renovated)."  I had an Apple II at the end of the 1970s beginning in the 1980s and had an iPhone 4 and still have an iPad 2, but my office has always been a windows box.  So I'm really a newbie on the Mac.  My main job is as an image maker and photographer, using Adobe products. I am become familiar with the software and the new terms and had a few questions.

    My Windows workstation had 4 screens and would like to have 3 screens, on the iMac.  I understand the port Thunderbolt is what I would use, but don't know if I should get some sort of converter hub and put a Thunderbolt port or run each monitor on its own Port. I don't know, what other material may be used on the stroke, if you want advice from other users.  Even if my PC monitors are near the resolution of the iMac, and most of my image work will be done on the main screen, other screens will be used for e-mail, research on the web and others.

    I also use a mouse from the ball on my PC (usb) and I was wondering if it will work on the material of the iMac.  I have a little of magic, as seems to be quite an easy and intuitive interface.

    In any case, I'm sure it's frustrating for users of long-time Mac products to meet a beginner, but advice, links or suggestions would be greatly appreciated.

    Thank you very much.

    You can use any external screen mini display port. Plug the cable from port mini display on the Thunderbolt on Mac ports, and then you're in business. Connection of external monitors an iMac is extremely simple to do. Apple explains in OS x: how to use several displays with your Mac in Lion mountain and even before - Apple Support. Although this letter of advice is a bit outdated, it should still work properly with your new iMac.

    Insofar as your new magic Track Pad, it may take a little 'getting used to' However, after a week or two, you will get the hang of it. You can find the gestures to use multi-touch on your Mac - Apple Support useful too.

    There is a plethora of information available for Windows users, go on a Mac. I would like to start with https://www.apple.com/support/macbasics/

    Furthermore, to make your messages more readable, use paragraph breaks. We would appreciate that.

  • new newbie question

    A few background questions: I'm new cs4, Web page design, so I decided to give it a go and have a bit of frustration but love all the DW. I did not any computer of programming since the BACK on a commodore 128 in high school... Although w3schools, adobe tv and youtube are moving me... lol

    I use 3 columns locked with header and footer

    1. I added a table to the my content, just below the title of the content and three photos.  Each photo (jpg) is taken from my site images folder and inserted in the top row.  They were previously seen on the design and mode live view and preview in the browser but now just shows Design view and does not appear in mode live view or seen by Preview in the browser. I deleted and reinserted them without change and I've debugged and have no problem but me being a novice... what I am doing wrong or is - it a bug and some simple, easy for a guy not experienced to understand?

    2. can you use the panels reducible spry in a table?  I tried earlier and my site got weird on me, so I removed it.  I already have my nav, so it would be more than a list of data in the area of the environment page?  Can I use the data list instead?  I like the idea that it is reducible to a type of menu.

    I have also read through the forums and hats help for us newbies

    Thank you

    I can't see your pictures so I have no way of knowing which ones shows and those who don't.  This is why it is so much better for us if you download the page to the web server and that you post a URL for us to see.

    In your code, I see problems with path. You have this in the header:

    Followed by here later on (notice the first slash images before?):

    airportpic
    

    and this in your footer (no slash leader before the images):

    I hope that this will put you on the right PATH.

  • Frustration with updates: what about emoticons

    As a student at the University of Texas Tech, I am frustrated with the change of the emoji barrel of a gun to fire squirt. While your intentions may have been good, end gun violence based on a change of a single emoji clearly won't happen. The spirit of our school is hampered online because we can is no longer ' Let's raise our guns! Other schools, like the OSU and customers are frustrated. I request a review. How is someone supposed to take the Texas Tech Almighty seriously if I put a gun to squirt on my post of the day of the game?

    Hello.

    On my laptop, I see that the Apple Music Playlist Dance Workout is there but I can't add it to my Ipod. How can I listen to that without the help of my phone? That's what I bought an Ipod for and I pay every month. Its no use to me here. How can I add it to my playlist? Help! Very frustrated.

    Apple's music is not compatible with the iPod nano. See the notes at the bottom of:

    http://www.Apple.com/music/

    1. Apple's music is not available on iPod nano and iPod shuffle.

    The reason is that the Apple's music is a subscription service, so if you have to cancel, you don't get to keep the music you downloaded while you had it. The iPod nano has no Internet capability so there is no way to check the status of your subscription.

  • I can't get videos play in Firefox until I close Firefox and reopen it. Super frustrating!

    I keep Firefox open at almost any time and when I load a new page and try and play a video, that this is on youtube, Facebook or another source, it will not play. He stays right on the loading circle all the time. The only time where things happen is when I completely quit Firefox and re - start. It's pretty frustrating for me because I often have several tabs open with I'm working on other things that I don't want to close. I would appreciate any advice. Thank you

    These are going to close, and then restart Firefox, reload of the current session.

    Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem.

  • Y at - it app in option for Photos?  This application is the application of most frustrating I've ever used

    Photos app frustrates me.  I can't do simple things such as importing a photo in an email without having to open the Photos app and drag and drop a picture in an open email.  Cannot even name a file.  It only adds a tag.  I want something like the photo app in Windows.

    Many, many, many alternatives - look in the App store on internet or on MacUpdate or other Mac software site

    But since you have not bothered to learn to use pictures, it is likely that any attempt to software to use without worrying to learn yu will also be all or most frustrating

    attaching photos to send is well documented and trivial - pictures called a pure help in the menu featured bar - open it and check out the Photos

    help on using Apple Mail

    Use e-mail to share photos

    You can use Mail to send photos directly from Photos. When you use E-mail to send pictures in e-mail, Photos sends the first account in your Mail preferences. If you have other e-mail accounts configured in Mail preferences, you can select which e-mail account to send email when you send it.

    Note: When you use E-mail to send a live picture, the Live Photo is transferred as a still image only.

    Tip: If you have a lot of files or files to send, you can use the mailbox to send. You must have an iCloud account to use the mailbox. You can use the mailbox to send attachments up to 5 GB in size directly from Mail on your Mac, or icloud.com/mail on your Mac or PC. All file types are supported and attachments do not count against your storage iCloud.

    Open pictures for me

    1. Select the photos you want to send. You can send photos from your photo library or an album, but not a slideshow or a project (for example, a book, card, or calendar).
    2. Click on the Share button in the toolbar and choose Mail.Mail opens a message with attached photos.
    3. Type the e-mail address of the recipient in the field, and then type a subject line in the subject field.
    4. Type a message if you want, and then click Send.
    5. Or other programs

    Share items with other applications and websites

    You can easily share your photos on a third party Web site by adding an extension for the site to your menu to share.

    When you open the share menu, you see a list of extensions that already uses pictures. To share with other applications, you can download the apps (and their sharing extensions) from the Mac App Store, then activate the extensions in the menu share.

    Open pictures for me

    1. Click on the Share button on the toolbar. The share menu opens and displays the pictures extensions already uses.
    2. Choose, share more in the menu. The Extensions of the system preferences pane opens.
    3. Click the share Menu on the left.
    4. Check the box next to each extension you want to add to the drop action.

    After you add the extension in the menu share, you can select photos and share them with third-party application or website.

  • When I try to highlight text on any page why it automatically scrolls to the top? Very frustrating problem just occurred, was not there before.

    Curiously, an error just for me that was not there until tonight (I have nothing new installed on my firefox). When I try to highlight text on any page why it automatically scrolls to the top? Very frustrating problem, no matter whether on gmail on an email, facebook or a web page regular when I try to select my browser text is now scroll upward on its own literally as soon as I'm going to highlight, that means I end up selecting everything on the page when it scrolls upward. Can anyone shed some light on how I can solve this problem suddenly?

  • Since the download 29.0.1 I can no longer cut, copy and paste. So frustrating!

    Often, I copy and paste items in the forums of the site without problem. However, since I upgraded to 29.0.1 I can do is no longer only and it's so frustrating. I tried to do the extra steps click on your copy and paste items, but it does not help. I even tried downloading the AllowClipboard Helper, but that no longer works. I never needed this add-on in the past.

    Hi karenbills, in fact, the fox icon is part of the title bar. To display the title bar, you can use customize and click the button at the bottom left of the title bar.

  • Ads pop up on the new MacBook Air. Very frustrating.

    I just plug a new MacBook Air on the weekend. I used help migration to transfer my files from one to the other. I think that it might cause a problem because whenever I try to use Safari and click a link, or anywhere on a page, it opens a new tab for a page popup for a betting site or similar. This was also a problem on my old MacBook. I was told that it was just slow. I understand there are a lot of these questions, but I can't find an answer which is quite recent. How can I solve this... Very frustrating and obviously it shouldn't be a virus/malware on a new product so could come from the former? Help!
