1,398,892 | 1,398,893 | asp.net: moving from session variables to cookies | <p>My forms are losing session variables on shared hosting very quickly (webhost4life), and I think I want to replace them with cookies. Does the following look reasonable for tracking an ID from form to form:</p>
<pre><code>if(Request.Cookies["currentForm"] == null)
return;
projectID = new Guid(Request.Cookies["currentForm"]["selectedProjectID"]);
Response.Cookies["currentForm"]["selectedProjectID"] = Request.Cookies["currentForm"]["selectedProjectID"];
</code></pre>
<p>Note that I am setting the Response cookie in all the forms after I read the Request cookie. Is this necessary? Do the Request cookies copy to the Response automatically?</p>
<p>I'm setting no properties on the cookies and create them this way:</p>
<pre><code>Response.Cookies["currentForm"]["selectedProjectID"] = someGuid.ToString();
</code></pre>
<p>The intention is that these are temporary header cookies, not persisted on the client any longer than the browser session. I ask this since I don't often write websites.</p>

5,957,809 | 5,957,810 | Java escaped sequence syntax error | <p>I'm trying to create a string array with lines of codes, so that the program can over-write a portion of existing code once it hits a mark. My problem comes on this line:</p>
<pre><code>var finalTitle = (str.replace("()", ("(" + num + ")")));
</code></pre>
<p>As I am attempting to convert that line into a valid string, I understand that the quotation mark can be somewhat tricky to parse. This is what I have so far:</p>
<pre><code>"var finalTitle = (str.replace(\"()\", (\"(\" + num + \")\")));"
</code></pre>
<p>However, eclipse will not stop complaining that the syntax of this line is incorrect. Does anyone know how to correctly format this line? Or possibly more specifically, how to parse quotation marks into a string?</p>
<p>Here is an example of the string array I am filling. I am going to loop through it with each iteration writing a new line to the .js file:</p>
<pre><code>String[] lines = {"var patientTree = getPatientMenuTree();", "var rootNode = patientTree.getNodeById('Patients');", "var str = rootNode.title;", "var num = patientArray.length;", "var finalTitle = (str.replace(\"()\", (\"(\" + num + \")\")));" };

4,418,728 | 4,418,729 | uint vs int in C# | <p>I have observed for a while that C# programmers tend to use int everywhere, and rarely resort to uint. But I have never discovered a satisfactory answer as to why.</p>
<p>If interoperability is your goal, uint shouldn't appear in public APIs because not all CLI languages support unsigned integers. But that doesn't explain why int is so prevalent, even in internal classes. I suspect this is the reason uint is used sparingly in the BCL.</p>
<p>In C++, if you have an integer for which negative values make no sense, you choose an unsigned integer.</p>
<p>This clearly signifies that negative numbers are not allowed or expected, and the compiler will do some checking for you. I also suspect in the case of array indices, that the JIT can easily drop the lower bounds check.</p>
<p>However, when mixing int and unit types, extra care and casts will be needed.</p>
<p>Should uint be used more? Why?</p>

2,838,008 | 2,838,009 | Selective Service permissions, binding only | <p>Is it possible to restrict access to a <code>Service</code> such that a client can only bind to it? For example, I want clients to access the service's AIDL API, but do not want them to be able to call <code>startService()</code> or, more importantly, <code>stopService()</code> on the service.</p>
<p>I have tried using the <code>android:permission</code> attribute within the <code><service></code> tag of the manifest. This works for restricting access to <code>startService()</code> and <code>stopService()</code> but binding to the Service configured in this way results in:</p>
<blockquote>

<p>Any thoughts?</p>

5,403,699 | 5,403,700 | How to decide when to introduce a new type instead of using list or tuple? | <p>I like to do some silly stuff with python like solving programming puzzles, writing small scripts etc. Each time at a certain point I'm facing a dilemma whether I should create a new class to represent my data or just use quick and dirty and go with all values packed in a list or tuple. Due to extreme laziness and personal dislike of <code>self</code> keyword I usually go with the second option. </p>
<p>I understand than in the long run user defined data type is better because <code>path.min_cost</code> and <code>point.x, point.y</code> is much more expressive than <code>path[2]</code> and <code>point[0], point[1]</code>. But when I just need to return multiple things from a function it strikes me as too much work.</p>
<p>So my question is what is the good rule of thumb for choosing when to create user defined data type and when to go with a list or tuple? Or maybe there is a neat pythonic way I'm not aware of?</p>

<p>I am thinking to pass a collection structure of some kind in order for the methods to be able to build the group by's and the where clauses. </p>
<p>Let's say a list containing the field and the value for the group by or where.</p>
<p>Am I going to the right direction?</p>
<p>Update:</p>
<p>I dont have code yet but let me try to explain better:</p>
<ol>
<li>We have a form with 10 dropdownlists and a checkmark beside them.</li>
<li>Also we have adatagrid on the form.</li>
<li><p>Every dropdownlist corresponds to a field in a table.</p>
<ul>
<li><p>If a dropdownlist has its checkbox checked means that it must be part of the group by clause in the select statement.</p></li>
<li><p>The value of the dropdownlist must be part of the where clause.</p></li>
</ul></li>
</ol>
<p>*<strong>note: *</strong> Another application could have different numbers of dropdownboxes and different corresponding fields.</p>
<p>I want to create a common method that will retrieve data with user selectable group by and where clauses.</p>
<p>So what i think is to pass to the method 2 lists.</p>
<ul>

2,775,384 | 2,775,385 | What is the most efficient way to save game status in Android? | <p>I have a game app that save game status in the onPause() function of the game board activity.</p>
<p>That seems very wasteful, because the user might be briefly switching to another app and return to play later. But if they never return, my app could be garbage collected and the status gets lost, so I save it just in case. </p>
<p>I think status gets saved many times for every time it gets read. Is there a better way to lazily save the status when I know they are leaving the app? </p>
<p>Does anybody know of a guaranteed callback that I could use? e.g. if I move the save status code to onDestroy(), it might never get called. </p>
<p>Is there a way to leverage onSaveInstanceState() to help?</p>

<p>For the purposes of my of the EXE running in the process, I can just call <code>Process.Close()</code> to exit without any side-effects, but the <code>Process</code> object is only known to the <code>worker_DoWork()</code> method, so I'll need to keep track of the <code>Process</code> instance for cancellation purposes... that's why I'm hoping there might be a better way.</p>
