I am beginner of Android and there are so many things I confused.
For now, I want to know how to control system resources and services like bluetooth, SMS, phone contacts etc.
Honestly, i want to know how or what to do to control sms usage based on user behavior, block incoming call or change it to auto vibrate mode without user noticed like that.
Actually, I want it for my assignment about context aware access control paper.
I choose Android for implementation but i am afraid i
couldn't submit my paper in time if i study android from the beginning and all by myself.
Tutorials (especially with full sample code) would be fine for me.
No offense but I want to avoid errors.
I feel my head becomes swollen whenever "force close error" show as I need it urgent.
Thanks in advance!

I get the information and close this popup window, so now i am on my main window, then again I click on the link for that data entry form, so the popup window comes up but i lost the information that I have entered, it's because I am opening the popup window once again, and the new popup window will replace the existing popup with the same name.</p>

3,720,761 | 3,720,762 | C# Custom Attribute Alternatives | <p>Currently, I've created a class with ~30 properties to be set. This is done to build up a URL request later on(ie, "http://www.domain.com/test.htm?var1=a&var2=b...&var30=dd").</p>
<p>The issue I'm facing is the property names don't necessarily match the query variable names(this is intended to be different). For example, I may have a variable titled "BillAddress", whereas the query variable will need to be "as_billaddress".</p>
<p>I have no control over the query variable naming scheme as these are set at an external source.</p>
<p>One possible solution I've used is creating a custom attribute and decorating the properties with their respective query counterparts:</p>
<pre><code>[CustomQueryAttribute("as_billaddress")]
string BillAddress{get;set;}
</code></pre>
<p>To retrieve the attribute though, requires a little reflection and due to the larger number of properties, I was curious if there is a neater way to accomplish this functionality. Not so much as setting/retrieving custom attributes without reflection, but being able to tie an alternate string variable to any property.</p>
<p>I've also pondered about setting each variable up as a sort of KeyValuePair, with each key representing the query counterpart, but I didn't get too far in that thought.</p>
<p>To summarize/clarify my above backstory, what would you do to associate a string with a property(not the value of the property)?</p>
<p>As always, any comments are greatly appreciated.</p>

3,842,213 | 3,842,214 | how to catch the event when the particular application process is being suspended using task manager? | <p>I am developing a simple application where in we have predefined quotas on usage for each user on the system..
and if the quota is up..the system should logoff of the user account..
this will happen if the application is allowed to run..
but if the user is closing the application on his own ..the app should automaticaly logoff the account..</p>
<p>i did exactly that in writing forced logoff code in form-closing event..
but if we are closing the app/process using the taskmanager..
the form closing event is not being called.
and so the user is able to continue even if his quota of time is up..
can anybody helpme out with this..</p>

405,800 | 405,801 | Constructor help with const C-string array | <p>I have a simple class Name:</p>
<pre><code> class Name
{ private:
char nameStr[30];
public:
Name(const char * = "");
char * getName() const;
void print() const;
};
</code></pre>
<p>I am having two problems, which are just a bit difficult for me wrap my head around. The constructor is supposed to take an argument of <code>const char *</code> and copy that into the nameStr array. However, this is what I have tried and is not working:</p>
<pre><code>Name::Name(const char * setName)
{
&nameStr = setName;
}
</code></pre>
<p>It gives me the error "invalid lvalue in assignment". If I remove the reference in front of nameStr, it still errors, saying "incompatible types in assignment of 'const char*' to 'char[30]'". Not quite sure what I'm missing.</p>
<p>The other problem is the accessor method:</p>
<pre><code>char * Name::getName() const
{
return &nameStr[0];
}
</code></pre>
<p>I have the same problem, it errors "invalid conversion from 'const char*' to char*'" and I can't for the life of me figure out how to make it return a pointer to a const char... I've been searching to avail. Found plenty of info on const, but can't quite figure how to apply it to my situation. Any help would be greatly appreciated!</p>

757,229 | 757,230 | Setting padding of a shape resource / GradientDrawable in code | <p>I have an xml file with a selector in it that defines the different states for a button:</p>

<item android:state_pressed="true" android:drawable="@drawable/custom_green_button_selected_state" />
<item android:state_enabled="false" android:drawable="@drawable/custom_green_button_disabled_state" />
<item android:drawable="@drawable/custom_green_button_normal_state"/>
</selector>
</code></pre>
<p>Then in each of my drawable xmls I have information on how the button looks like this:</p>
<pre><code><shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient android:type="linear" android:gradientRadius="180"
android:startColor="#6b9f41" android:endColor="#598a3d" />

<padding android:left="15dp" android:right="15dp" android:top="10dp"
android:bottom="10dp" />
</shape>
</code></pre>
<p>For most of the buttons in my app I just apply the first xml as the background and everything works fine. For a specific button, I'd like to use the same xmls but make the button skinnier by changing the padding of the drawables. I thought I'd try creating a new StateListDrawable in my code and adding a mutate of each of the individual state's drawable xmls, however, these drawables show up as GradientDrawables which doesn't seem to give me access to their padding properties. Any ideas?</p>

841,468 | 841,469 | C# Get Name of Derived Type from Inside base Class | <p>I am troubleshooting a problem in handling a mouse event in a base class. Since breakpoints don't really work well for troubleshooting mouse events, I want to add some debug output in the event handler. However, it's important for me to include the name of the actual derived class in the debug info as the event handling code in the base class is shared by a large number of derived classes and only certain ones exhibit the problem. </p>
<p>I tried using this.GetType().Name but this simply returns the type of the base class. I can, of course start modifying the classes and, say, pass the derived class type to the base class constructor where it can store it but this is a lot of changes for what is obviously only a temporary need. Is there a simple way to get the type of the derived class from within the base class? </p>
