1,909,193 | 1,909,194 | Using regex to avoid if elifs | <p>I'm new to Python, which I'm using to do an ugly little put-this-tabular-data-into-a-db conversion. The program looks at the data, creates a table in MySQL, and then reads the data into the table. In this section, header row text is checked to make some decision about data typing. I had an idea that I could be clever and do this with a single regex rather than if/elifs. My solution works for this case at least, where I don't have to worry about multiple matches. What I'm asking is, is there any real merit to this approach in terms of efficiency?</p>
<pre><code>def _typeMe(self, header_txt):
# data typing
colspecs = {
'id':'SMALLINT(10)',
'date':'DATE',
'comments':'TEXT(4000)',
'flag':'BIT(1)',
'def':'VARCHAR(255)'
}
# regex to match on header text e.g. 'Provisioner ID'
r = re.search(re.compile('(ID$)|(Date)|(Comments$)|(FLAG$)', re.IGNORECASE), header_txt)
checktype = lambda m: max(m.groups()).lower() if m else 'def'
return colspecs[checktype(r)]

I'm trying to render this as an image so I thought it would be a good idea to try to convert it to an image object and then use the save function for images to save the image to a path on my computer. However, every time I run it I get an argument exception error. Before I was catching the error it said my parameter was invalid, but I don't understand how that's the case because I'm pretty sure my syntax is right and I filled my "sorted" byte array in the program so I don't get how it could be invalid... Any help would be appreciated- Plus I haven't even gotten to my save method yet because it keeps on breaking so I don't know if this works at all!</p>

(Manually you can change this setting in 'Sound & Display Settings')</p>
<p>Changing e.g. the airplane mode can be done with the following code:</p>
<pre><code>private void setAirplaneMode(boolean bOn)
{
Settings.System.putInt(getContentResolver(),
Settings.System.AIRPLANE_MODE_ON,
bOn ? 1 : 0);
Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
intent.putExtra("state", bOn ? 1 : 0);
sendBroadcast(intent);
}
</code></pre>
<p>However, for 'haptic feedback' this does not work because I don't find a corresponding intent.</p>
<p>Simply</p>
<pre><code>private void setHapticFeedbackMode(boolean bOn)
{
Settings.System.putInt(getContentResolver(),
Settings.System.HAPTIC_FEEDBACK_ENABLED,
bOn ? 1 : 0);
}
</code></pre>
<p>does not work (I guess a broadcast of an intent is really necessary).</p>
<p>I am not interested in things like <code>setHapticFeedbackEnabled</code>, because in that way you are only changing the way how the calling app/view is handling haptic feedback.
I am looking for a way to change the global setting. (Like if you were checking/unchecking the checkbox in 'Sound & Display Settings' manually.)</p>

I've heard of ADODB, ODBC, DB2, and OLEDB. Can someone show me an example of the syntax for getting one of these methods to work? I'd prefer to use a method that isn't dependent on having certain software such as client access, and am trying to avoid using something like ODBC due to the fact you have to configure the DSN.

<p>I spoke to the developers of Sygic and they told me this is the expected result for the activity (obviously not the expected behavior of an android activity) and they do not seem very willing to change this (I suspect its bad programming on their part).</p>
<p>What I have been trying to do all day is figure out a way where I can either override the finish() method, I have tried casting to Activity and calling finish but that didnt seem to work.</p>
<p>I have looked at instead of calling finish, starting the main menu activity from within the sygic activity with a number of flags set, but I think android is still calling finish on the sygic activity.</p>
<p>So does anyone know how to override the finish method, or "minimize" an activity so that it doesn't ever actually close.</p>

Conceptually, all I understand is that a method "does" something and that a class is a "blueprint". I've read all the analogies, but the only thing that really makes sense to me so far is:
Loops,if then, variable assignments, primitive data types, and the basic syntax.</p>
