can some one help me find the errors on this program
Public Class DemoUpper
Private Sub btnDisplay_Click(sender As Object, e As EventArgs) Handles btnDisplay.Click
Const strLowerCase As String = "visual basic"
strLowerCase = strLowerCase.ToUpper
txtOutput.Text = strLowerCase
End Sub
End Class
Try using the CODE tags around the text so it gets formatted correctly. Or paste it here and post the link http://pastebin.com/

You've declared "strLowerCase" as constant, so you can't assign a value to it, you can only read it. So, the working code should look like this:
Code:
Public Class DemoUpper
Private Sub btnDisplay_Click(sender As Object, e As EventArgs) Handles btnDisplay.Click
Dim strLowerCase1 as string
Const strLowerCase As String = "visual basic"
strLowerCase1 = strLowerCase.ToUpper
txtOutput.Text = strLowerCase1
End Sub
End Class
But also you can make it shorter like this:
Code:
Public Class DemoUpper
Private Sub btnDisplay_Click(sender As Object, e As EventArgs) Handles btnDisplay.Click
Const strLowerCase As String = "visual basic"
txtOutput.Text = strLowerCase.ToUpper
End Sub
End Class

I'm wondering if anyone can give any pointers...
I'm trying to wake my TyTN from it's slumber in c#... after a few hours research I found an example in the MSDN that will set my "Beep" program to run at a certain time buy using CeRunAppAtTime. The problem is that although it works ... if the phones sleeping the screen doesn't activate ... (cont below)
Code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using HowDoI.Examples;
namespace DemoRunAppAtTimeCS
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void menuTest_Click(object sender, EventArgs e)
{
DateTime startTime = DateTime.Now + new TimeSpan(0, 0, 30);
long fileStartTime = startTime.ToFileTime();
long localFileStartTime = 0;
Win32.FileTimeToLocalFileTime(ref fileStartTime, ref localFileStartTime);
SystemTime systemStartTime = new SystemTime();
Win32.FileTimeToSystemTime(ref localFileStartTime, systemStartTime);
Win32.CeRunAppAtTime(@"\Windows\Beep.exe", systemStartTime);
}
}
}
Not a problem ... I know the programs activating so I thought if I mess about with the BKL1: and set it to "on" using DevicePowerState my test app will activate and the screen and speaker will then kick into life.
The problem is that it activates ... the screen comes on and then starts flashing or locks on so you can't turn it off without a reset. The speaker doesn't activate at all..... Can anyone shed anylight?? I'm not bothered about the screen but would love the speaker to activate to I can play a alarm.
Cheers

It's late so I can't be arsed trying this, but it looks like you haven't PInvoked the API call properly...
Try this
Code:

static extern int SetSystemPowerState(string psState, int StateFlags, int Options);
const int POWER_STATE_ON = 0x00010000;
const int POWER_STATE_OFF = 0x00020000;
const int POWER_STATE_SUSPEND = 0x00200000;
const int POWER_FORCE = 4096;
const int POWER_STATE_RESET = 0x00800000;
#endregion
internal static void PowerOn()
{
SetSystemPowerState(null, POWER_STATE_ON, POWER_FORCE);
}
P.S. Check PInvoke.net and MSDN On SetSystemPowerState for more info.

Cheers Dave,
I'll give it a try tomorrow ... got a bottle of plonk in me and busy cooking a fish finger sandwich!!

You're a star Dave ... ... changed my test program as per your advice and it works a treat!!! It wakes up even when locked, screen active, speaker active.
Thanks again for your help Dave ... I spent 10 hours on it yesterday with no joy!! Below's the code so maybe it'll help someone else.

If anyone every wonders how ... if you've set an application to run at a certain time, you can cancel the request by setting the run date/time to null
Win32.CeRunAppAtTime(@"\Windows\Beep.exe", null);

Hi guys,
Would we be able to alter the Quick Setting menu in Sense 2.1 and create an extra setting for Auto Rotate?
I'm sure it would be possible.
If anyone has some idea on how to do it, please reply.
I'm not very experienced with android. I'm just starting to learn.
But I'm sure we could team up to try and create a simple Quick Setting like this.
I already decompiled Rosie.apk and had a look inside, but didn't get anywhere.
Hope to hear from you guys.

I would grab a SystemUI.apk that already has the mod, the stock apk they used as a base and compare the two. Should give you a better understanding.

Sorry for the deadness... Didn't have time, to busy being on a holiday.
Anyhoo. I decompiled a Stock SytemUI.apk from HTC Sense 2.1.
This also has code in the SystemUI.apk for autorotate in the quick settings.
It seems like it has already been written but somehow it is not activated.
In the smali/com/android/systemui/statusbar/preference/ folder,
There are smali's for Brightness, BT, GPS, Hotspot, Rotation, Setting, Mobile Network, WiFi, Quick Settings and some more.
What do these files do?
Some of the names show up in the Quick Settings menu, but (i.e.) Brightness and Rotation do not.
How do we add these features, any ideas?
Cheers,
Daan

Ive tried out a few of them working as they should. But seems hes updating to a new base...dont know if they are gonna work after that.
Will this work on HTC Hero (GSM) with this sense 2.1 rom HEROINE++??
Hiya,
So I have the hook I need, but I need to get a context. The object I'm in doesn't have a Context member, but it does have an ActivityManager object, and ActivityManager has a context.
The problem is that ActivityManager is an internal class, so I can't do this:
Code:
ActivityManager am = (ActivityManager) XposedHelpers.getObjectField(param.thisObject, "mAm");
Context context = (Context) XposedHelpers.getObjectField(am, "mContext");
I tried this, on a hunch:
Code:
Context context = (Context) XposedHelpers.getObjectField(param.thisObject, "mAm$mContext");
but that didn't work either.
Is there a way to get a field from a nested, internal object?
Thanks!
Ryan
Nevermind. Dumb question. Obviously, you do this:
Code:
Object am = (Object)XposedHelpers.getObjectField(param.thisObject, "mAm");
Context context = (Context) XposedHelpers.getObjectField(am, "mContext");
I've been using Android Studio for a while, and it's one of the (if not the) most powerful IDE's I've used.
There is one thing I can't find though.
If you have a list like this:
Code:
private String username = null;
private String userAvatarURL = null;
private String bio = null;
private String birhtdate = null;
private String gender = null;
private String location = null;
private String twitter = null;
private String externalURL = null;
private String urlIFLprofile = null;
private String urlIFLwallpapers = null;
private List<Integer> wallpaperIdArray = null;
How do you change private to public without changing them one by one?
Thanks for the tip!

such as
