  • Do I lose the benefits of macro recording if I develop Excel apps in Visual Studio?

    - by DanM
    I've written lots of Excel macros in the past using the following development process: Record a macro. Open the VBA editor. Edit the macro. I'm now experimenting with a Visual Studio 2008 "Excel 2007 Add-In" project (C#), and I'm wondering if I will have to give up this development process. Questions: I know I can still record macros using Excel, but is there any way to access the resulting code in Visual Studio? Or do I just have to copy and paste then C#-ize it? What happens with my "Personal Macro Workbook"? Can I use the macros I have stored in there within C#? Or is there some way to convert them to C#? If there is some support for opening and editing VBA macros in Visual Studio, can you provide a very brief summary of how it works or point me to a good reference? Do you have any other tips for transitioning from writing macros in VBA using Excel's built-in editor to writing them in C# with Visual Studio?

  • Is MS Access still the most efficient RAD tool for small-scale custom apps?

    - by FastAl
    Of the many other development tools I've used, nothing holds a candle to the 'Functionality to Development Effort' ratio of MS Access. The reason I am asking is that I have been out of the language selection process for a few years, working on a large .Net system, and am only anecdotally familiar with the latest development tools outside the .Net world. I'm well aware of the limitations of Access, but for a limited concurrency (usually only 1 user at a time), small business, custom app, has anybody found a comparable end-to-end solution or combination that comes close? It doesn't have to be free, open source, or even Windows based. It just has to allow the same speed of development and maintenance, and maybe even provide some additional amenities like seamless autointegration with a server-based DB Engine (like Access does with its own 'Jet' dbms), better web support, and a file format more compatible with source control. I don't want to miss out on anything. Please share your development experience with your suggestions. Thanks.

  • Not sure what happens to my apps objects when using NSURLSession in background - what state is my app in?

    - by Avner Barr
    More of a general question - I don't understand the workings of NSURLSession when using it in "background session mode". I will supply some simple contrived example code. I have a database which holds objects - such that portions of this data can be uploaded to a remote server. It is important to know which data/objects were uploaded in order to accurately display information to the user. It is also important to be able to upload to the server in a background task because the app can be killed at any point. for instance a simple profile picture object: @interface ProfilePicture : NSObject @property int userId; @property UIImage *profilePicture; @property BOOL successfullyUploaded; // we want to know if the image was uploaded to out server - this could also be a property that is queryable but lets assume this is attached to this object @end Now Lets say I want to upload the profile picture to a remote server - I could do something like: @implementation ProfilePictureUploader -(void)uploadProfilePicture:(ProfilePicture *)profilePicture completion:(void(^)(BOOL successInUploading))completion { NSUrlSession *uploadImageSession = ..... // code to setup uploading the image - and calling the completion handler; [uploadImageSession resume]; } @end Now somewhere else in my code I want to upload the profile picture - and if it was successful update the UI and the database that this action happened: ProfilePicture *aNewProfilePicture = ...; aNewProfilePicture.profilePicture = aImage; aNewProfilePicture.userId = 123; aNewProfilePicture.successfullyUploaded = NO; // write the change to disk [MyDatabase write:aNewProfilePicture]; // upload the image to the server ProfilePictureUploader *uploader = [ProfilePictureUploader ....]; [uploader uploadProfilePicture:aNewProfilePicture completion:^(BOOL successInUploading) { if (successInUploading) { // persist the change to my db. aNewProfilePicture.successfullyUploaded = YES; [Mydase update:aNewProfilePicture]; // persist the change } }]; Now obviously if my app is running then this "ProfilePicture" object is successfully uploaded and all is well - the database object has its own internal workings with data structures/caches and what not. All callbacks that may exist are maintained and the app state is straightforward. But I'm not clear what happens if the app "dies" at some point during the upload. It seems that any callbacks/notifications are dead. According to the API documentation- the uploading is handled by a separate process. Therefor the upload will continue and my app will be awakened at some point in the future to handle completion. But the object "aNewProfilePicture" is non existant at that point and all callbacks/objects are gone. I don't understand what context exists at this point. How am I supposed to ensure consistency in my DB and UI (For instance update the "successfullyUploaded" property for that user)? Do I need to re-work everything touching the DB or UI to correspond with the new API and work in a context free environment?

  • How can I communicate between Windows 8 and WP8 apps using ssl?

    - by Clay Shannon
    I'm considering using either raw notifications (WNS) or sockets for communication between a Windows 8 and WP8 app. I've found some samples for using sockets but my question[s] here are: does WP8 support sending/receiving messages over ssl and, if so, how is it done? Something I need to be true or find a workaround for is that the Windows 8 app has a permanent IPAddress to which the phone app will send its updates. Typically, a tablet will be running Windows 8 app, always listening for incoming messages; the phone app will periodically send messages.

  • Sharing code between two or more rails apps... alternatives to git submodules?

    - by jtgameover
    We have two separate rails_app, foo/ and bar/ (separate for good reason). They both depend on some models, etc. in a common/ folder, currently parallel to foo and bar. Our current svn setup uses svn:externals to share common/. This weekend we wanted to try out git. After much research, it appears that the "kosher" way to solve this is using git submodule. We got that working after separating foo,bar,common into separate repositories, but then realized all the strings attached: Always commit the submodule before committing the parent. Always push the submodule before pushing the parent. Make sure that the submodule's HEAD points to a branch before committing to it. (If you're a bash user, I recommend using git-completion to put the current branch name in your prompt.) Always run 'git submodule update' after switching branches or pulling changes. All these gotchas complicate things further than add,commit,push. We're looking for simpler ways to share common in git. This guy seems to have success using the git subtree extension, but that deviates from standard gitand still doesn't look that simple. Is this the best we can do given our project structure? I don't know enough about rails plugins/engines, but that seems like a possible RoR-ish way to share libraries. Thanks in advance.

  • why does the gingerbread emulator orientation gets stuck in apps?

    - by tabjsina
    At first I thought this was a problem with my app, but it seems to be happening in any app (though interestingly, not the home screen) in the gingerbread emulator. To replicate my issue, open eclipse and fire up the android emulator for gingerbread (I'm using the "Google APIs - API Level 9" as my target) So the procedure to duplicate once the emulator loads is press LCtrl-F11 to shift orientation to landscape, then again to switch to portrait Result: In the homescreen: The view rotates to landscape, and then back to portrait, as expected In any app (i've tried browser, calculator, maps, and the app i'm currently working on): the view rotates to landscape, and then nothing, it stays in landscape even the emulator is displaying the phone in landscape mode (see below) http://i54.tinypic.com/2ake06v.jpg Has anyone else had this issue, or have I installed the emulator in some incorrect way - this hasn't been an issue with any of the previous emulators

  • How do I have my apps dialog box pop up and take focus from the current running app?

    - by simba
    I know this type of thing is looked negatively upon but I write software for people with disabilities and sometimes good gui practices don't make sense. In this case, the user interacts with a assistive interface and under certain conditions, my control app needs to prompt the user with a question. My background process creates a dialog (I'm using wxwidgets wxDialog class) and calls Show(). The dialog box appears but it does not have focus (the application that the user was previously using keeps it). Since my users can't use mice, they can't simply click on the window. I've tried calling show and then followed by SetFocus(HWND) but that doesn't do it. What's the problem? Is this even possible? Window7. I'm thinking that it might have something to do with it being a dialog and not a full window (wxFrame). Any help is greatly appreciated.

  • What the best multi-thread application debugger for C++ apps.

    - by Coredumped
    I'm looking for a good multi-thread-aware debugger, capable of showing performance charts of application threads on Linux, don't know if such a thing exists, perhaps as a Eclipse plugin. The idea would be to track per thread memory allocation a CPU usage as well as being able to interrupt a thread and examine its stack trace, local vars, etc. It does not have to be an eclipse plugin or a free tool, do any of you have heard of something similar?

  • See socket options on existing sockets created by other apps?

    - by nailer
    I'd like to test whether particular socket options have been set on an existing socket. Ie, pretty much everything you can see in: #!/usr/bin/env python '''See possible TCP socket options''' import socket sockettypelist = [x for x in dir(socket) if x.startswith('SO_')] sockettypelist.sort() for sockettype in sockettypelist: print sockettype Anyone know how I can see the options on existing sockets, ie those created by other processes? Alas nearly all the documentation I read on Python socket programming is about making new sockets.

  • does Apple allow template style apps to pass review?

    - by user1159677
    I have an app which will go to our clients and then they can have their clients install it. Meaning there would be multiple versions of the master app but with customization per client. example 200 of our clients get the master app and then can customize it (text and images only via web) Will Apple allow something like this? Is there another way to get around this distribution model? I guess a good example of it would be a real estate agent having an app that's customized and on the app store but it's still Brand XYZ's app. thanks in advance

  • Is there an off the shelf CMS that can be used as a back end for smartphone travel guide apps?

    - by eamonncarey
    I'm wondering if there's an off the shelf CMS available that is similar to something like Mobile Roadie - ie: it will allow you to create multiple versions of one application? I'm looking to develop some mobile travel guides for iPhone/Android/Blackberry etc, and rather than get a CMS built, I'd like to see if there's something out there is similar to Wordpress in that it will allow us to input text, images, Google Maps details, phone numbers, email addresses and potentially some audio/video content. If anyone knows of anything, I'd love to hear about it. Also, if you have any ideas regarding pricing, that would be extremely helpful! Thanks in advance for your assistance.

  • SVN update a working copy when parents are updated

    - by ruckuus
    I have two SVN branches and I plan to partially copy the first working copy to another. I did this: Libs /home/user/projects/libs/{lib1, lib2, lib3} Core /home/user/projects/Apps/{libs,core} svn copy --parents /home/user/projects/libs/lib1/* /home/user/projects/Apps/libs/1 svn copy --parents /home/user/projects/libs/lib2/* /home/user/projects/Apps/libs/2 svn copy --parents /home/user/projects/libs/lib3/* /home/user/projects/Apps/libs/3 The question: My peers are still working on /home/user/projects/libs/lib1, and when this repository is updated with new codes, I want my /home/user/projects/Apps/libs also updated. Is there any way to do that "automatically"? I tried to do with the same svn copy command, and of course it fails with: svn: Path '/home/user/projects/Apps/libs/1' already exists

  • 8 Things You Can Do In Android’s Developer Options

    - by Chris Hoffman
    The Developer Options menu in Android is a hidden menu with a variety of advanced options. These options are intended for developers, but many of them will be interesting to geeks. You’ll have to perform a secret handshake to enable the Developer Options menu in the Settings screen, as it’s hidden from Android users by default. Follow the simple steps to quickly enable Developer Options. Enable USB Debugging “USB debugging” sounds like an option only an Android developer would need, but it’s probably the most widely used hidden option in Android. USB debugging allows applications on your computer to interface with your Android phone over the USB connection. This is required for a variety of advanced tricks, including rooting an Android phone, unlocking it, installing a custom ROM, or even using a desktop program that captures screenshots of your Android device’s screen. You can also use ADB commands to push and pull files between your device and your computer or create and restore complete local backups of your Android device without rooting. USB debugging can be a security concern, as it gives computers you plug your device into access to your phone. You could plug your device into a malicious USB charging port, which would try to compromise you. That’s why Android forces you to agree to a prompt every time you plug your device into a new computer with USB debugging enabled. Set a Desktop Backup Password If you use the above ADB trick to create local backups of your Android device over USB, you can protect them with a password with the Set a desktop backup password option here. This password encrypts your backups to secure them, so you won’t be able to access them if you forget the password. Disable or Speed Up Animations When you move between apps and screens in Android, you’re spending some of that time looking at animations and waiting for them to go away. You can disable these animations entirely by changing the Window animation scale, Transition animation scale, and Animator duration scale options here. If you like animations but just wish they were faster, you can speed them up. On a fast phone or tablet, this can make switching between apps nearly instant. If you thought your Android phone was speedy before, just try disabling animations and you’ll be surprised how much faster it can seem. Force-Enable FXAA For OpenGL Games If you have a high-end phone or tablet with great graphics performance and you play 3D games on it, there’s a way to make those games look even better. Just go to the Developer Options screen and enable the Force 4x MSAA option. This will force Android to use 4x multisample anti-aliasing in OpenGL ES 2.0 games and other apps. This requires more graphics power and will probably drain your battery a bit faster, but it will improve image quality in some games. This is a bit like force-enabling antialiasing using the NVIDIA Control Panel on a Windows gaming PC. See How Bad Task Killers Are We’ve written before about how task killers are worse than useless on Android. If you use a task killer, you’re just slowing down your system by throwing out cached data and forcing Android to load apps from system storage whenever you open them again. Don’t believe us? Enable the Don’t keep activities option on the Developer options screen and Android will force-close every app you use as soon as you exit it. Enable this app and use your phone normally for a few minutes — you’ll see just how harmful throwing out all that cached data is and how much it will slow down your phone. Don’t actually use this option unless you want to see how bad it is! It will make your phone perform much more slowly — there’s a reason Google has hidden these options away from average users who might accidentally change them. Fake Your GPS Location The Allow mock locations option allows you to set fake GPS locations, tricking Android into thinking you’re at a location where you actually aren’t. Use this option along with an app like Fake GPS location and you can trick your Android device and the apps running on it into thinking you’re at locations where you actually aren’t. How would this be useful? Well, you could fake a GPS check-in at a location without actually going there or confuse your friends in a location-tracking app by seemingly teleporting around the world. Stay Awake While Charging You can use Android’s Daydream Mode to display certain apps while charging your device. If you want to force Android to display a standard Android app that hasn’t been designed for Daydream Mode, you can enable the Stay awake option here. Android will keep your device’s screen on while charging and won’t turn it off. It’s like Daydream Mode, but can support any app and allows users to interact with them. Show Always-On-Top CPU Usage You can view CPU usage data by toggling the Show CPU usage option to On. This information will appear on top of whatever app you’re using. If you’re a Linux user, the three numbers on top probably look familiar — they represent the system load average. From left to right, the numbers represent your system load over the last one, five, and fifteen minutes. This isn’t the kind of thing you’d want enabled most of the time, but it can save you from having to install third-party floating CPU apps if you want to see CPU usage information for some reason. Most of the other options here will only be useful to developers debugging their Android apps. You shouldn’t start changing options you don’t understand. If you want to undo any of these changes, you can quickly erase all your custom options by sliding the switch at the top of the screen to Off.

  • SQLAuthority News – Android Efficiency Tips and Tricks – Personal Technology Tip #003

    - by pinaldave
    I use my phone for lots of things.  I use it mainly to replace my tablet – I can e-mail, take and edit photos, and do almost everything I can do on a laptop with this phone.  And I am sure that there are many of you out there just like me.  I personally have a Galaxy S3, which uses the Android operating system, and I have decided to feature it as the third installment of my Technology Tips and Tricks series. 1) Shortcut to your favorite contacts on home screen Access your most-called contacts easily from your home screen by holding your finger on any empty spot on the home screen.  A menu will pop up that allows you to choose Shortcuts, and Contact.  You can scroll through your contact list and then just tap on the name of the person you want to be able to dial with a single click. 2) Keep track of your data usage Yes, we all should keep a close eye on our data usage, because it is very easy to go over our limits and then end up with a giant bill at the end of the month.  Never get surprised when you open that mobile phone envelope again.  Go to Settings, then Data Usage, and you can find a quick rundown of your usage, how much data each app uses, and you can even set alarms to let you know when you are nearing the limits.   Better yet, you can set the phone to stop using data when it reaches a certain limit. 3) Bring back Good Grammar We often hear proclamations about the downfall of written language, and how texting abbreviations, misspellings, and lack of punctuation are the root of all evil.  Well, we can show all those doomsdayers that all is not lost by bringing punctuation back to texting.  Usually we leave it off when we text because it takes too long to get to the screen with all the punctuation options.  But now you can hold down the period (or “full stop”) button and a list of all the commonly-used punctuation marks will pop right up. 4) Apps, Apps, Apps and Apps And finally, I cannot end an article about smart phones without including a list of my favorite apps.  Here are a list of my Top 10 Applications on my Android (not counting social media apps). Advanced Task Killer – Keeps my phone snappy by closing un-necessary apps WhatsApp - my favorite alternate to Text SMS Flipboard - my ‘timepass’ moments Skype – keeps me close to friends and family GoogleMaps - I am never lost because of this one thing Amazon Kindle – Books my best friends DropBox - My data always safe Pluralsight Player – Learning never stops for me Samsung Kies Air – Connecting Phone to Computer Chrome – Replacing default browser I have not included any social media applications in the above list, but you can be sure that I am linked to Twitter, Facebook, Google+, LinkedIn, and YouTube.
