I (or rather, all of us...) need some code, and I've never really done any Javascript.
Could someone please code:
- Enable all controls on form 0 of a document.
- Walk through all the controls in order. For each control:
- Make a temporary string that holds the name of the control
- add a slash and the value of the control if it is a checkbox
- Walk through all the controls again
- Disable any controls:
- whose name is longer, but starts with the temp string above
- which are radiobuttons whose name is the temp-string
- done
This would disable any controls that do not apply when the user deselects a higher-level checkbox or radio-button, which would look much cleaner and cooler. I would have to spend most of today on this learning enough Javascript and fixing stupid beginner-bugs, and I would be disapointed if we don't have at least a few people here who can code this in 10 minutes.
Code can be tested by copying the form from the kitchen locally and creating a function to replace the submit placed at every checkbox or radiobutton control.
ok, consider this a beta
i did not follow your design in whole
but still i hope the functionality is the same
email me to [email protected] for any needed changes
my local time is 2:31 after midnight
uh uaah, good night
Code:
<html>
<head>
<script>
function setupDisable() {
var myForm = document.getElementById('myForm');
// enable all of them
for(var i=0; i<myForm.elements.length; i++) {
myForm.elements[i].disabled = false;
}
// foreach assign a tmpName
for(var i=0; i<myForm.elements.length; i++) {
var tmpName = myForm.elements[i].name;
if (myForm.elements[i].type == 'checkbox') {
// IMHO this is not needed and will break the functionality
// and this fact renders this whole cycle useless :)
// you can just use the name
// property in fuiction doDisable...
//tmpName += '/' + myForm.elements[i].value;
}
myForm.elements[i].tmpName = tmpName;
}
}
function doDisable(root) {
// disable all children
var myName = root.tmpName;
var myForm = document.getElementById('myForm');
if (!root.checked) {
alert('went off');
for(var i=0; i<myForm.elements.length; i++) {
var actName = myForm.elements[i].name;
if (actName.indexOf(myName) == 0 && actName != myName) {
myForm.elements[i].disabled = true;
}
}
} else {
alert('went on');
for(var i=0; i<myForm.elements.length; i++) {
var actName = myForm.elements[i].name;
if (actName.indexOf(myName) == 0 && actName != myName) {
myForm.elements[i].disabled = false;
}
}
}
}
</script>

I've been beating my head against the wall on this, so it's time to ask for help.
I've ported my game engine from iPhone to Windows CE (it actually started out many years ago as a WinCE engine, so I've developed it with portability in mind). I've also maintained a Windows build (full windows) all along for development.
I'm having problems initializing OpenGL ES on the HTC Touch Pro 2. Now what is maddening is that one of the builds worked fine, but I can't reproduce that success.
For starters, I'm linking to the Vincent OGLES implementation. If I use the Vincent libGLES_CM.DLL on a Dell x50v then it renders fine using software (so it's very slow - I haven't begun to see about using the GLES lite hardware implementation on that device yet). So is using the Vincent implementation without the software renderer DLL the correct method on a device like the TP2?
I tried this OpenGL ES SDK:
http://www.khronos.org/message_boards/viewtopic.php?f=11&t=1433
But it crashes on the first call to any OGLES API (eglGetDisplay). So I assume the linker lib is not mapping correctly to the TP2's DLL.
With Vincent it is failing at eglCreateContext, which returns EGL_BAD_ATTRIBUTE. If I do not specify an attribute list (which I see is how many other implementations call that routine) then it crashes. If I send an attribute array just containing EGL_NONE then it also crashes. It has to have at least one actual attribute to not crash.
I'm using attributes that are valid, and have tried many, many combinations, but it still returns EGL_BAD_ATTRIBUTE.
Any suggestions would be greatly appreciated.
Here's the code. I've tried calling eglCreateContext before and after eglCreateWindowSurface, because I've seen implementations do it both ways, but it made no difference.
Code:
g_hMainDC = GetDC(hWnd);
EGLConfig* configs = NULL;
const EGLint configAttribs[] =
{
EGL_RED_SIZE, 5,
EGL_GREEN_SIZE, 6,
EGL_BLUE_SIZE, 5,
EGL_ALPHA_SIZE, EGL_DONT_CARE,
EGL_DEPTH_SIZE, 16,
EGL_STENCIL_SIZE, EGL_DONT_CARE,
EGL_SURFACE_TYPE, EGL_WINDOW_BIT,
EGL_NONE
};
glesDisplay = eglGetDisplay(g_hMainDC);
if (!glesDisplay) {
return false;
}
if (!eglInitialize(glesDisplay, NULL, NULL)) {
return false;
}
EGLint num_configs = 0;
if (!eglGetConfigs(glesDisplay, NULL, 0, &num_configs)) {
return false;
}
if (num_configs==0) {
return false;
}
configs = new EGLConfig[num_configs];
eglGetConfigs(glesDisplay,configs,sizeof(EGLConfig),&num_configs);
EGLConfig config = NULL;
if (!eglChooseConfig(glesDisplay, configAttribs, &config, 1, &num_configs)) {
return false;
}
if (num_configs==0) {
return false;
}
if (config==NULL) {
return false;
}
// Let’s create our rendering context
glesContext=eglCreateContext(glesDisplay, config, EGL_NO_CONTEXT, configAttribs);
if(!glesContext) {
return false;
}
glesSurface = eglCreateWindowSurface(glesDisplay, config, hWnd, NULL);
if (!glesSurface) {
return false;
}
Okay. Finally got a handle on this. You can't pass attributes to eglCreateContext or eglCreateWindowSurface or it will always return EGL_BAD_ATTRIBUTE. It has to be an empty array or a NULL pointer.
My app was running out of memory on the stack, and it would fail in eglCreateContext. I increased the stack size in the link settings and that fixed it. I had played around with the stack size earlier, and reverted my settings because it did not appear that had anything to do with the OGL ES initialization problems I was having.
Try to google the Xperia SDK which come with workable OpenGL ES samples.
I'm currently playing with SMS Backgroud task sample(Windows 8) sample application
I'm trying to display the Received SMS message onto the form but it is being processed on another "Project properties SMSbackgroundTask" which contains no form and my main form in project properties "Smsbackgroundtasksample"
I created this in SMSbackgroundtask
Code:
setSMSBody(smsTextMessage.Body);
Under
async void DisplayToastAsync(IBackgroundTaskInstance taskInstance, ManualResetEvent manualEventWaiter)
and
Code:
public void setSMSBody(string bodyy)
{
string body;
body = bodyy;
}
All in the backgroundtask(no form)
I'm trying to read it from the form project (SMSBackgroundTasksample) but i cant read it even tho its public..
I did this because i didnt know where i can intercept the MEssage from in the main page which i believe because it havent been processed at the main SMSbackgroundtask.
The following is the codes in backgroundtask (if you know where to intercept)
Code:
(SMSbackgroundtask)
using System;
using System.Diagnostics;
using System.Threading;
using Windows.ApplicationModel.Background;
using Windows.Storage;

//
public void Run(IBackgroundTaskInstance taskInstance)
{
//
// Associate a cancellation handler with the background task.
//
taskInstance.Canceled += new BackgroundTaskCanceledEventHandler(OnCanceled);
ManualResetEvent manualEventWaiter = new ManualResetEvent(false);
manualEventWaiter.Reset();
//
// Do the background task activity.
//
DisplayToastAsync(taskInstance, manualEventWaiter);
//
// Wait till the async operation is done. We need to do this else the background process will exit
//
manualEventWaiter.WaitOne(5000);
Debug.WriteLine("Background " + taskInstance.Task.Name + ("process ran"));
}
async void DisplayToastAsync(IBackgroundTaskInstance taskInstance, ManualResetEvent manualEventWaiter)
{
SmsReceivedEventDetails smsDetails = (SmsReceivedEventDetails)taskInstance.TriggerDetails;
SmsDevice smsDevice = (SmsDevice)await SmsDevice.FromIdAsync(smsDetails.DeviceId);
SmsBinaryMessage smsEncodedmsg = (SmsBinaryMessage)await smsDevice.MessageStore.GetMessageAsync(smsDetails.MessageIndex);
SmsTextMessage smsTextMessage = Windows.Devices.Sms.SmsTextMessage.FromBinaryMessage(smsEncodedmsg);
XmlDocument toastXml = ToastNotificationManager.GetTemplateContent(ToastTemplateType.ToastText02);
XmlNodeList stringElements = toastXml.GetElementsByTagName("text");
stringElements.Item(0).AppendChild(toastXml.CreateTextNode(smsTextMessage.From));
stringElements.Item(1).AppendChild(toastXml.CreateTextNode(smsTextMessage.Body));
ToastNotification notification = new ToastNotification(toastXml);
ToastNotificationManager.CreateToastNotifier().Show(notification);
setSMSBody(smsTextMessage.Body);
manualEventWaiter.Set();
}
public void setSMSBody(string bodyy)
{
string body;
body = bodyy;
}
//
// Handles background task cancellation.

It would be nice if you could also teach me how to send using this library

Thanks. I believe it would greatly improve my skills. Hope you could help me out. Thank you
For some reason, my MTCD unit with Malaysk Rom did not allow me to set long press function to a steering wheel button set for volume. Not sure if it is Malaysk rom or factory rom, or MCU not is causing this issue.
So, in order to fix this problem, I used an Arduino to interpret steering wheel button inputs and send different signal for short press and long press to the head unit.
Also, my car does not have steering wheel radio buttons, so I utilized cruise control buttons.
I'm sure it would be possible to do the same in the head unit's firmware it self, but I did not know where to begin, so I chose the path I know will work.
I check long press for buttons I will be using for volume only (Up and down) and other buttons are just passed to reflect actual button status.

This is the circuit I have built. Very simple circuit with a digital potentiometer to send different resistance for each button press.
This is the after soldering parts. Ignore wires at the bottom. I didn't realized copied version of Arduino pro mini did not come with bootloader preloaded, so I had to tap into some pins to program the chip directly first using avr programmer.
Added a 100 ohm resistor to a relay in order to protect it from higher voltage normally present in an automobile. The absolute maximum voltage of the relay I used was 15V and normal operating voltage is 12V. I did not want risk breaking it.
This button allows me to select between cruise control and remote control. This is what controls the relay in the circuit.
Hook up everything, and it is good to go. I used ACC power to power the circuit, since there is no reason to keep it running when radio is not on.
Up -> Volume Up
Long Up (1 sec) -> Previous
2+ Sec Up -> Repeat Long Up every sec
Down -> Volume Down
Long Down (1 sec) -> Next
2+ Sec Down -> Repeat Long Down every sec
Pull -> Play/Pause
Push -> Mode
Long Push -> Home (Using head unit's built in long press button assignment).
Following is my code. I'm sure it is not the best code, but it works.

Dude... That is f** awesome!! But I hardly doubt that anyone will be willing to go through the same just to get the long-press function =)) I ll keep waiting for the software solution
Kudos!! Awesome job and very simple - but you just have to come up with the idea.
Respect!

It is actually quiet simple. Whole thing cost me about $6 to make because I already had switches and relay. Chinese copy version of Arduino pro mini is only around $3 or less. Digital potentiometer is around $3 as well, but this can be replaced with resistor array and using 5 digital IO pins.
Digital potentiometer just makes it easier to change resistance values.

I wish someone cracks MCU of our device. Our device have great potential, but software is made to just barely functioning.
Hi guys i would ask your help. I have an Alfa Romeo Giulietta, Installed in the dash a nexus 7 2013 and I want use the steering wheel buttons. The car use the protocol is 15765-4 29bit and I have on Bluetooth obd reader. Can you please help me out? Thanks in advance.

Amazing work.... Many thanks
Wow a nice, clean, elegant and simple solution.
I've done it little bit different (Old Style) as my car model didn't had factory Steering wheel, so I made steering wheel upgrade that left me with 6 Wires to play with (3 for 6 Media Commands and 3 for 4 Cruise control). So I ended up with dismantle steering wheel commands setting up each command different by 20kOhm in parallel to outputs So I have 6 Main commands and any combination of two+ keys simultaneously for additional commands as I get 1/2 of sum Ohm of the commands pressed. and o the other side 4 Cruise control commands (do not have cruise control in Car) both commands Directly connected GND+KEY1 for Media Controls and GND+KEY2 for cruise control.
Now I only need to think how to emulate keyboard commands so that I can navigate Home Screen and emulate Swipe.
FYI I have not seen any ROM to allow Vol +/- long press as it is reserved for Vol Repeat mode
Works great for me, just so others may also take advantage of this code, I used the below for a Honda Jazz/Fit 2010 with a Kenwood Android Auto Head Unit, I only used the CH+/- and MODE for long press as I did not want to mess with volume triggers and 8 total controls is enough for me (just), not sure if anyone else had an issue but for me the lower resistance (higher potentiometer values) were the only ones that would work with my head unit.
Code:
// Car Steering Wheel Rmote w/ Cruise Control Buttons
// lambition
// 10/31/2016
// Using SPI controlled Microchip MCP41100 100K Digital Potentiometer for Output.
// Resistance Value calculated
// Termianl W => Ground, Terminal A => Head Unit Key Input, Terminal B => Leave open
// R_WA: Resistance between Wiper and terminal A.
// R_AB: Resistance between terminal A and B. (100k)
// R_W: Wiper resistance. 125 for 100k chip.
// R_WA(D_n) = ((R_AB * (256-D_n))/256+R_W
// 390.6 ohms per step (100k/256).
// Pin connections
// CS(1) -> 10 (CS)
// SCK(2) -> 13 (SCK)
// SI(3) -> 11 (MOSI)
// Vss (4) -> GND
// PA (5) -> Head Unit Key 1
// PW (6) -> GND
// PB (7) -> Open
// Vdd (8) -> 5V
// First byte is command, Second byte is data. MSB first.
// Command Byte
// X X C1 C0 X X P1 P0
// C1,C0 = 0,1: Write Data, 1,0: Shutdown, Ignore others.

My car is hyundai santafe 2010 with steering wheel button, I measure the Resistance Value between button and ground by pressing each button, the result are:
- Mode: 2.10 K ohm
- Up: 434 ohm
- Down: 1.12 K ohm
- Volume Up: 4.60 K ohm
- Volume Down: 6.81 K ohm
- Map: 10.72 K ohm
- Phone On: 41.00 K ohm
- Phone Off: 18.99 K ohm
I replace the other head unit (10" monitor of Suzuki XL7), so I want to use the steering wheel control of my Santafe to control the Suzuki XL7 head unit
The Suzuki XL7 head unit use Resistance Value for each steering wheel button are:
- Mute: 56 +- 0.6 Ohm
- Volume +: 131 +- 1.3 Ohm
- Volume -: 241 +- 2.4 Ohm
- Next: 1571 +- 15.7 Ohm
- Prev: 751 +- 7.5 Ohm
- Mode: 421 +- 4.2 Ohm
I read this thread many times and prepare
- Arduino Nano.
- resistor: 1K ohm
- MCP41100
- Converter 12v to 5V.
but I still not understand some code and parameter.
sparky3387, lambitioncan you explain more detail for me
the diagram of MCP41100 to Arduino and head unit key?
// MCP41100 8 Pin connections
// CS(1) -> D10 (Arduino)
// SCK(2) -> D13 (Arduino)
// SI(3) -> D11 (Arduino)
// Vss (4) -> GND
// PA (5) -> Head Unit Key 1
// PW (6) -> GND
// PB (7) -> Open
// Vdd (8) -> 5V
The value of INPUT_KEY is voltage or Resistance Value
// Input Key Voltages with 1k pull up resistor
// Change these values to what ever your switch is giving.
#define INPUT_KEYUP_V 315
#define INPUT_KEYDOWN_V 115
#define INPUT_KEYUP_CH 691
#define INPUT_KEYDOWN_CH 501
#define INPUT_KEY_MODE 839
Do I must change the value:
#define TOLERANCE_V 20
#define OFFSET 0.05
Can you add code to measure the value ò INPUT_KEY like this link:
