I am new to Xamarin. Can someone point me to a way to read existing SMSs using Xamarin Forms.
I know we can do it using Android specific libraries (and probably with iOS specific libraries as well). But, I want to use a library that will help me avoid using platform specific library.
You will have to use platform specific code for this. Remember; all libraries out there actually are platform specific code but just offer you an abstraction. This includes Xamarin.Forms itself.
As mentioned by Jason in the comments, you aren't going to be able to do this on iOS altogether, they do not allow to read or sends texts directly. So you should probably rethink what you are trying to do.
I need to convert applications wrote in Delphi XE3 to use it on a Mac OSX.
I use for this applicatiopn database SQLite but i cannot found firemonkey compatible components that i can use to connect with my databases.
How can i do?
Thank you
If you are talking about the high-level Delphi database components, then I cannot help you, but if it is about low level database access, without using the Delphi database components, here is what I did:
There is a SQLite interface included with Firemonkey. Include "System.Sqlite", in your uses section. I have only focused on iOS, which does not allow dynamic libraries, so the Firemonkey implementation comes in handy, as it automatically links the SQLite libraries into the executable.
I re-used and modified the SQLite3Wrap.pas, from my previous SQLite wrapper, to use the Firemonkey library and to make it work with NEXTGEN. So far it seems to work.
If you need to connect from Delphi XE3 to SQLite on Mac OSX, then you can use LiteDAC for this because these components are fully compatible with Firemonkey and support Mac OSX.
Hello friends I want to develop database application in windows phone using sqlite.I just want to know whether sqlmetal can be used in wp7 and also want to know does it supports .net v4.0 or any alternative solution is there. When I googled I came across using dblinq in sqlite. Please provide some sample for this.
I can't seem to find an example of using LINQ over SQLite on MonoDroid. Is there one available anywhere?
The sqlite-net library works well with Mono for Android and provides some LINQ support. I have a post here describing how to use it in Mono for Android applications.
I would like to build a graphical application that must work on at least Windows, Linux and MacOS. I would like to know what do you suggest I should use.
I have some experience with Java and C++ but I thought about using Java Swing first. What do you think or further suggest (like maybe tools or frameworks)? I also may be needing to connect to a PostgreSQL database to store data.
Java is probably the simplest way to get your application working on all 3 platforms as well as to add database support. All of these are equally possible in C++, but it definitely involves more work because you need to learn to use a cross-platform widget toolkit. Also, C++ database drivers usually have wildly varying designs but Java presents a unified interface via JDBC - this also means that you can change your underlying DB at any time without having to change your code.
I would use the Qt platform from Nokia. It supports all the OSes that you've mentioned and has also database connectors for PostgreSQL but also for MySQL, SQLite, etc.
It also has a very nice IDE, the QT Creator that you can use should you pick Qt.
I would suggest Qt too. Qt has seen very good development recently, their examples and documentation base is quite large, and the LGPL license is flexible too, for creating proprietary software. It has a good Qt Creator IDE, a Qt GUI Designer. Plus is has quite a number of modules, enabling it to be used in conjunction with other language developed apps/libraries. And, it is used in commercial/public apps like Google Earth, Skype (maybe only the linux version). So, it has a good history of reliability. And yeah, for Database, it has modules, like Qt-Sql. Another advantage you get over java is speed.
wxWidgets does cross-platform easily enough, using available native toolkits. You could probably use a ORM for the database part, but I don't have enough experience using them under C++ to provide an actual informed opinion there.
GTK is cross-platform. Pidgin uses it and manages to get away with being generally considered a fully-cross-platform app. The installer size is a problem, though.
