I am developing a PHP app that runs on an XDA2 PocketPC. It is for use by field engineers to book themselves to jobs whilst on-site, and it will update our internal stock system etc.
The need has arisen for signature capture, whereby a signature area is embedded into a web page and when the client signs the screen, it is transferred safely into a database at our offices.
I have looked at various possibilities but they all seem to rely on ASP/VBSCRIPT.
Has anyone ever come across something that will integrate with my PHP web app?
In a nutshell: Signature region in web page, user signs screen,signature data sent to a SQL database back at base.
Any ideas? :shock:
Hi limepickle
The webbrowser in WM2003 is really quite primitive in comparison to it's desktop counterparts these days. For that reason, i really do not think that you will find a way to do this in the browser.
I write software similar to that which you are talking about using .NET and i've considered using web pages once or twice for simpler apps, but signature capture was always the sticking point which I could never think of a way to acheive...
Sorry to disappoint you :roll:

Click to expand...
Click to collapse
your gonna get stuck with a php version since the pocket IE isnt that great,
perhaps you can find a flash based signature capture and has flash on the pocket pcs?
this is our solution:
i created a custom application to do this for our company,
its developed using the OpenNet Compact Framework.
its a fullscreen signature app and when the rep is ready to upload the signature they click the send button that transfers it to a ASP.NET web service. this then saves the image as Jpeg to a shared folder and also to SQL for archiving,
check out:

Yes, I think you're right, Flash will probably be the way to go, seeing as everyone seems to to be .NET / ASP crazy!!!!
LOL
PS. thanks Pope and djrm, I do appreciate you trying to help, its just that anything to do with .net vb etc, may as well be Urdu.
asp.net web signature capture control
You can try out http://mysignature.brinkster.net for this
Don't Necro old threads for shamelesly plugging your software..
Hallo,
I want to select preferred network operators automatically from device.
After I search for it, I found following:
Code:
final int EVENT_AUTO_SELECT_DONE = 300;
Message msg = mHandler.obtainMessage(EVENT_AUTO_SELECT_DONE);
phone.setNetworkSelectionModeAutomatic(msg);
So I need an instance of class "Phone". I tried this:
Code:
String phoneFactoryName = "com.android.internal.telephony.PhoneFactory";
String phoneName = "com.android.internal.telephony.Phone";
Class phoneFactoryClass = Class.forName(phoneFactoryName);
Class phoneClass = Class.forName(phoneName);
Method getDefaultPhone = phoneFactoryClass.getMethod("getDefaultPhone");
Object phoneObject = getDefaultPhone.invoke(null);
But the method "getDefaultPhone" can only called by looper.
Next I tried this:
Code:
String phoneAppName = "com.android.phone.PhoneApp";
Class phoneAppClass = Class.forName(phoneAppName);
Method getInstanceMethod = phoneAppClass.getMethod("getInstance");
Object phoneObject = getInstanceMethod.invoke(null);
But I get a ClassNotFoundException.
Can anybody help me, please?
sorry ,i can't help you
Yes it can be instantiated. But you have to overcome a couple of hurdles:
In your AndroidManifest.xml set
Code:
android:sharedUserId="android.uid.phone"
within the manifest-Tag. This is required to prevent a SecurityException from being thrown when protected Intents are sent by the methods you may invoke (like android.intent.action.SIM_STATE_CHANGED).
Set
Code:
android:process="com.android.phone"
in your application-Tag. This is required to allow the invocation of getDefaultPhone / makeDefaultPhone.
To do all this your app must be signed with the system signature key.
Hi!
I am trying to develop an android app with a google map v2, location service and some control buttons.
But I don't want to put all these things inside one MainActivity class. So I thought I could split all the code into some more classes. The MainActivity shall controll all the GUI things and react on map or location events...
Now I have the following problem. Inside my onCreate I instanziate the additional classes:
Code:
// Preferences as singleton
pref = Prefs.getInstance(this.getApplicationContext());
pref.loadSettings();
// Set up the location
loc = new Locations(pref);
loc.setCallback(this);
map = new MyMap(pref);
It seems to work fine. But inside the MyMap class every time I start the app a null pointer exception is thrown. When I am calling MyMap() the following code will be executed:
Code:
[...]
private Prefs pref;
private GoogleMap mMap;
[...]
public MyMap(Prefs prefs) {
pref = (Prefs) prefs;
if (mMap == null) {
FragmentManager fmanager = getSupportFragmentManager();
mMap = ((SupportMapFragment) fmanager.findFragmentById(R.id.map)).getMap();
[...]
}
The line with the findFragmentById is the one that causes the exception.
If I write
Code:
SupportMapFragment f = ((SupportMapFragment) fmanager.findFragmentById(R.id.map));
f is allways null. But how can I access the fragments and view elements defined within my MainActivity?
It works if I put the code inside my MainAcitivity.
Every class extends "android.support.v4.app.FragmentActivity"
I tried to save the application context within my Prefs() class, so that I can access it from everywhere.
But I don't know how to use it inside my additional classes.
How to share the "R" across all my classes?
Can someone help me please?
Thank you very much!!
Thorsten
Are you having trouble adding a Map to a Fragment? If so, then you may take a look at this tutorial. I haven't tried it myself since I couldn't install Google Play Services on my development device. If it helps, do write back, as I am definitely going to try it myself soon.
Hi all,
I build a software for myself that read from Whatsapp db (that stored on my android device)..
I trying to read from thumb_image column but cannot find the correct way ...
I write this software on c# language... and the code for read its column as follows:
//thumbImage is the value that stored in thumb_image column.
byte[] encodedbytes = System.Text.Encoding.Unicode.GetBytes(thumbImage);
string encoded = System.Convert.ToBase64String(encodedbytes);
byte[] utf8Decoded = System.Text.Encoding.UTF8.GetBytes(encoded);
File.WriteAllBytes("Images\\" + mdeiaName, utf8Decoded);
but it's not working, so i trying to use IronPython as following:
string pythonScript = @"import base64
class DecryptString(object):
def Decrypt(self, str):
return base64.b64encode(str).decode(""utf-8"")";
ScriptEngine engine = Python.CreateEngine();
ScriptSource source = engine.CreateScriptSourceFromString(pythonScript);
ScriptScope scope = engine.CreateScope();
source.Execute(scope);
dynamic DecryptString = scope.GetVariable("DecryptString");
dynamic decryptString = DecryptString();
var result = decryptString.Decrypt(thumbImage);
File.WriteAllText("Images\\" + mdeiaName, result);
but without success...
Can somebody help me?
This is my code.
Code:
Process p = Runtime.getRuntime().exec("su");
InputStream inputStream = p.getInputStream();
OutputStream outputStream = p.getOutputStream();
outputStream.write("screencap\n".getBytes());
outputStream.flush();
sleep(1000);
byte[] b = new byte[inputStream.read()];
inputStream.read(b);
System.out.println(b.length);
But b is empty.
I can get back by running screencap with adb. And I don't need to save to disk; I need to identify the image content.
