5,897,399 | 5,897,400 | Member-Function Pointers With Default Arguments | <p>I am trying to create a pointer to a member function which has default arguments. When I call through this function pointer, I do not want to specify an argument for the defaulted argument. This is disallowed according to the standard, but I have never before found anything that the standard disallowed that I could not do in some other conformant way. So far, I have not found a way to do this.</p>
<p>Here is code illustrating the problem I'm trying to solve:</p>
<pre><code>class MyObj

int bar(int val = 42) { return 2; }

typedef int (MyObj::*barptr2)();

198,465 | 198,466 | 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>

Javascript is relatively new to me, and this is the first time I've had to do this particular thing.</p>
<p>So, I'm trying to use a Modal to open an iframe - the page itself will have links to several modals, all of which need to be passed a different value. Rather than hardcode each of these, I'm trying to set it up in such a way that one function can be used and the links can pass the values as required.</p>
<p>The code I currently have successfully opens the modal, but a 404 error is inside it - plus the modal title shows + title + - so I guess I'm referencing it wrong (probably in the function?).</p>
<p>Heres what I've got, pointers in the right direction would be appreciated!</p>
<pre><code>function openIframe(title,url){
$.modal({
title: '+title+',
url: '+url+',
useIframe: true,
width: 600,
height: 400

<a href="http://ideone.com/KQytD" rel="nofollow">http://ideone.com/KQytD</a> </p>
<p>Scroll down output #2 worked properly but output #3 did not. Some how when I pushed the value back into the stack and when I popped it it had the +'43' because of the ASCII and I cannot seem to get it into a regular integer value so I can do these operations easily.</p>
<p>line 116 puts input into char postfix. NOTE: input must be in postfix notation line 117 puts the single integer value into final after it has run through the function.</p>
<p>convertPostfixToEvaluation works as such: I scroll through each index of postfix until I read in '=' then I output the total/sum. The first if statement pushed the operands (0-9) into a stack. The second if statement if it reads in an operator then it attempts to do the operation as such in lines 134-158. After the if statements I increase the index value by 1 so it can scan the entire array.</p>
<p>The issue lies within the switch where I try adding,subtracting,multiply, or dividing more than 3 operands. so the 3rd one i believe is still has the value (+43 because of the ASCII).</p>
<p>My outputs(on the bottom of my program) show what the awkwardness is.</p>

1,401,744 | 1,401,745 | how to refresh the datagridview when new rows has been added | <p>hi i am a student of c# and working in winform i have a problem here to refresh the datagridview with new values i have a mainform in which i have a datagridview the data in the datagridview is filled up with the code</p>
<p>i have a second form which is invoked from a button on the main form as <code>showdialog</code>and the main form is running behind and there is one more button on the second form which is submit button. there are some controls on the second form from then the data is inserted into the database table, the table which is connected to the datagridview of main form so i want when the form second is opened and data is filled then when submit button is pressed so after <code>this.hide();</code> when the main form is visible then the submitted data should be in the datagridview
i have searched and found that changing the datasource would result in the datagridview to refresh with new data so i tried this</p>
<pre><code>MAINSOFTWARE ms = new MAINSOFTWARE();
ms.dataGridView1.DataSource = null;
ms.dataGridView1.DataSource = ms.bindingSource1;
this.Hide();
</code></pre>
<p>but it is not refreshing the gridview with new submitted data so now is there any way to refresh?</p>

392,383 | 392,384 | Get the instance name of this | <p>Is this possible!!?!?!?!?</p>
<p>I'm trying to make a set of classes that model a number of different types of things. Properties of these things change over time, and I want my code to be easy to maintain, so I want to do something like the following:</p>
<pre><code>public class Cat
{
public string CatName { get; set; }
public Cat()
{
this.CatName = MAGICSTUFF.GetInstanceName(this);
}
}
</code></pre>
<p>Somewhere else, when I want to get at those cats, I want to be able to say:</p>
<pre><code>[TestMethod]
public void test_awesome_cats()
{
Cat Tiger = new Cat();
Assert.IsTrue(Tiger.CatName.Equals("Tiger"));
}
</code></pre>
<p>So, I'm trying to map my naming convention into object properties. The part I can't figure out is the MAGICSTUFF.GetInstanceName. Is that a thing?</p>
<p>I suspect this is impossible, so if that's the case hopefully somebody can give me some other ideas on clever ways to use convention for this type of scenario. I've been thinking of using attributes for the Cat class for a while, but I like this was a lot better if its possible.</p>

Can u imagine this: douring the period of those 20 seconds, you can 'accidentally' roll the mouse in and out at least 10 times.</p>
