I have a set list of military times, i.e:
0030
0100
0130
0200

<p>All in half hour increments. How would I select the closest time to now.
For example.
User clicks on the button, php gets the time it is now, and selects the closest time variable. So if it's 0144, it would pick 0130. and if it's 0146, it would pick 0200.</p>

4,059,949 | 4,059,950 | Confused about activity lifecycle usage in the notepad example | <p>I am confused about activity lifecycle usage in the notepad example,notepad example use "edit in place" user model,inserting new record in onCreate method,
saving persistent state in onPause method,and save away the original text in onSaveInstanceState method.
I am a J2EE programer,I can not understand the logic described above. why not make things simple as following:</p>
<p>1.Not inserting new record in onCreate method.
2.When user pressing BACK,it is equal as pressing save button in the editorform,so execute inserting or updating in onPause method if activity.isFinishing() is true.
don't persiste use data if activity.isFinishing() is not true.
3.Not save the original text in onSaveInstanceState method,It is no necessary.If the activity is killed and back,restore user inputing data in the editorForm is adequately.</p>
<p>I think this logic is more traditional and natural.
Maybe I not understand the essence of the activity lifecycle.Please air your's opinion.</p>
<p>Thanks</p>

3,275,801 | 3,275,802 | Adding a color filter to a Drawable changes all Buttons using the same Drawable | <p>I have a screen where multiple Buttons use the same background Drawable. I have reusable code I use in various projects to add an OnTouch listener that adds a gray color filter while a button is being touched. That usually works fine, but in this case ALL the buttons are tinted when any of them is pressed.</p>
<p>I see an explanation in <a href="http://developer.android.com/guide/topics/graphics/2d-graphics.html" rel="nofollow">http://developer.android.com/guide/topics/graphics/2d-graphics.html</a>:</p>
<pre><code>Note: Each unique resource in your project can maintain only one state, no matter how many different objects you may instantiate for it. For example, if you instantiate two Drawable objects from the same image resource, then change a property (such as the alpha) for one of the Drawables, then it will also affect the other.
</code></pre>
<p>The suggested solution is to use a TweenAnimation, which does not seem to work with color filters.</p>
<p>I also saw <a href="http://stackoverflow.com/questions/7979440/android-cloning-a-drawable-in-order-to-make-a-statelistdrawable-with-filters">Android: Cloning a drawable in order to make a StateListDrawable with filters</a> which suggests using drawable.getConstantState().newDrawable(). This does not seem to make a difference. I'm guessing that as long as the same physical image file is used, all Drawables will be affected by a change to any other Drawable using the same resource.</p>
<p>What solution is there, other than creating a second background image to show the pressed state? It would be nice to have a simple programmatic solution I can add to my code and use in every project.</p>

5,418,148 | 5,418,149 | Can someone give me an overview of ASP.net and how it's different from technologies such as php? | <p>I've been doing the html and css for a site, sending it off to a guy to implement in a web server. I get a call from the designer freaking out about the progress, saying the clients aren't happy. He wants me to personally integrate my css with what's on the site. The site is done in ASP.net, time is short, and I'm a little in over my head. I have an understanding of how php works, but have never worked extensively with it.<br>
Looking at the stuff on the ftp, I can't even find equivalent of the index.html file (I know that when I go to the site itself, there is nothing after the base url, i.e., www.site.com/ brings me to the homepage.)</p>
<p>Can anyone give me a few tips or links as to what I am to do with this, or where to even being navigating this site? </p>
<p>EDIT: It's -not- a .Net Web Application, from the looks of it. </p>

5,359,316 | 5,359,317 | How to write a Loop | <p>I am working on something and I am stumped with 2 things. </p>
<p>The first is, I am trying to make a sort of counter that uses <code>PostMessage</code> to type from 0000 to 3600.
I need it to stop every few times it PostMessage the number and execute another part of the code, then after that code is done continue for another say 10 times then execute that same code, and so on. </p>
<p>Second: I need a function that will detect if a certain color is in a certain pixel, and if it is then it will execute some more code.</p>
<p>Here's the code that I tried, but failed with: </p>
<pre><code>void loop()
{
int start = Convert.ToInt32(textbox1.Text);
for (int i = start;i == 9999; i++)
if(i == 0004)
PostMessage(hWnd, WM_CHAR, i, 0);
}
</code></pre>
<p>Here's the last version, which also does not work:</p>
<pre><code>void function()
{
for (int i = 0000; i <= 3600; i++)
{
PostMessage(hWnd, WM_CHAR, i, 0); //PostMessage i
PostMessage(hWnd, WM_KEYDOWN, 0x0d, 0x1c0001); //Press Return
Sleep(1000); //System.Threading.Thread.Sleep
if ((i % 4) == 0)
{
Execute(); //My Code Block to execute after i tries 4 times.
}
}
}

4,265,185 | 4,265,186 | How to retweet a specific tweet? | <p>I wanna make a simple software that does the following:</p>
<ol>
<li>I tweet from a twitter account (eg 5 times a day)</li>
<li>The software should retweet my tweets from the accounts that I am following my primary account</li>
</ol>
<p>This is all.</p>
<p>What I did:</p>
<p>I made a software to tweet from it. Basicly you input, username password of primary account and your tweet that you wanna tweet. It will tweet on twitter, what you wrote (I made this just to have the text [tweet], not to search for the text in the twitter page). </p>
<p>So basicly, I have the tweet that I am looking for, but don't know how to tell him, search for that text, and click retweet.</p>
<p>Any ideeas ?</p>
<p>I made this in C# and I am doing it now in winautomation, will try my luck.</p>
<p>Any ideeas are appreciated.</p>
<p>Thanks</p>

<p>A user can only enter text in either inputs a or inputs b. </p>
