View 1 RepliesSince I am answering 2 threads about communication between 2 applications and that I talk about memoryMapFile in these posts I am posting this for those that can be interested Even if the MemoryMapFile exist since a long time in the native code world, it is new with the framwork4 in managed code.I would start by saying that if you look at the examples showed in the documentation, the control is done using Mutex ... It is what you DON'T want to do The right way is to use window message to automate The example here is: 2 applications, one with 2 buttons and a label.
Button1 ask the second application to start Notepad and Button2 ask the second application to stop it When the second application has executed the command asked by the first application, it send back a string that the first application show in the label The buttons are only enabled when both application have show that they are ready for the communication

View 2 RepliesI am starting a new project in VB, a card game modelled to be similar to a real card game.
I have the majority of the program planned out and have even started coding parts of it; my problem comes with the networking.This is a real-time card game (not turn-based) and I want to be able to play with real people (family mostly, so over LAN is what I'm after).
I have tried searching for code samples but I everything I have found seems more complicated than I feel is required for the task, introducing a lot of new concepts and not explaining them.
What I'm after is a simple way to exchange the information in real-time, I don't care so much for efficiency (at the moment) just ease of use - though if I need to wade through a heap of documentation I will. A perfect answer would tell me what the names of some of the controls/methods that would be appropriate are, even if it just re-affirms a bit of the complexity, you do not have to detail anything if you don't want to I just feel a bit at loss as to what exactly it is I am looking for!
Ok i know theres a program called eclipse for which you can download android plugins that let you develop application for the Android MObile Phones using the Android SDK.Is there any similar interface/plugins or anyway what so ever, that will allow you to develop apps for the android using say vb.Net 2008??

I have a .Net WCF Rest service returning Json to be consumed by an Android app.
In debug, the WCF service correctly has the return value (Json) as:
{"BaseLoyaltyPoints":1480,"BonusLoyaltyPoints":0,"BrandId":1414, [etc...] }
Also in debug, when it returns to Notepad, the return value has changed to:

We are using a .net wizard control for a mobile website. Everything works great except on android devices when the user exits the browser to take a call or send a text message. When the user returns to out web page the android browser is refreshing the web page. Our problem is when the web page refresh the wizard is losing the view state So if they are in the middle of the wizard there previous work is lost. how to combat this. Is there a way to persist the wizard even if the user refreshes the webpage? I basically want to make my asp.net wizard control truly stateless.
View 1 RepliesWe are developing an Android Application (Java) that reads an image, encode the bytes in base64 to send them over HTTP (via GET) to a WebService written in VB.NET.On .NET side, they are using this :

How can I pass the correct string to them to correctly decode the image from Java encoding (unsigned) to .NET decoding (signed)?

I have an ArrayList in android that I'm trying to convert to a Base64 String, then passing that to a wcf service though JSON and the wcf service inserts the string into a database. Then I need to be able to read that from the database and deserialize it in a .NET application.
This is how I am serializing the ArrayList in android:
private String convertByteArrayToSave(byte[] b){
if(b != null){
return Base64.encodeToString(b,0,b.length,Base64.DEFAULT);
}else{

The ultimate goal is to be able to be able to create a list of these shapes in the .NET app or android app and be able to read the list in the .NET app and android app no matter where it was created from. I'm able to it when you create the Shape from .NET and read it into android using WCF but creating it in android.

View 1 RepliesThe situation is this. I have an application written in vb.net. it consists or two parts. One on a PC and the other on a handheld windows mobile 6 device . The desktop program transfers a SQLServer compact database to and from the handheld device using activesync via USB. Potentially we want to look into having android handheld devices also supported by this application. Now I know I can use SQLite with .net. I know I can use ADB to push and pull data (and therefore the database files) to and from the device.
What I need to know is can I access ADB directly from VB.NET as an API or SDK rather than having to do it manually.
Unless of course I'm missing something and I can copy databases to and from the device in some other way?
I have used .NET and ShDocVw for years to grab data off webpages without any issues I couldn't overcome. This website has me beat though. It seems like such as easy task to grab the titles and other information off a library search page, but I can't see the data to be able to grab it. Usually, I just look in the DOM, but the data wasn't there. I did a view source, but the data wasn't there.
