**Debug &gt; Delete All Breakpoints**

or

**Shortcut** : &lt;kbd&gt;CTRL&lt;/kbd&gt; + &lt;kbd&gt;SHIFT&lt;/kbd&gt; + &lt;kbd&gt;F9&lt;/kbd&gt;

This works in *Debug mode* as well.

I personally find it easier to hold ALT, and double-press D.  
Which translates to &lt;strong&gt;D&lt;/strong&gt;ebug menu, &lt;strong&gt;D&lt;/strong&gt;elete All Breakpoints.


In Excel 2007, how do I add a description and parameter hints to a user-defined function? When I start typing a function invocation for a built-in function, Excel shows a description and parameter list--a tooltip. I&#39;d like to do the same for the functions I define.

Not just for the formula insert wizard, but in the formula box, so if I key `&quot;=myFun(&quot;`, at the `&quot;(&quot;` the tooltip pops up just like it does for `&quot;=average(&quot;`

There&#39;s no help in VBA Help, none on MSDN and none on any of the Excel and VBA dedicated forums I can find, so this is clearly a long shot.

How to put a tooltip on a user-defined function

What&#39;s the difference between `ob_flush()` and `flush()` and why must I call both?

The [`ob_flush()` reference][1] says:
&gt; This function will send the contents of the output buffer (if any).

The [`flush()` reference][2] says: 
&gt; Flushes the write buffers of PHP and whatever backend PHP is using (CGI, a web server, etc).

However, it continues to say:
&gt; [it] may not be able to override the buffering scheme of your web server…


So, seems to me that I could just use `ob_flush()` all of the time. However, I get strange results when I do that.  Could someone explain in simple terms what&#39;s going on here?

I come from a C++ background, so apologies if this is a non-C# way of thinking, but I just need to know. :)

In C++ if I have two pointers, and I want to know if they point to the same thing, I can look in the memory/watch window and see their value - to see if they are pointing to the same memory space.

In C#, I haven&#39;t been able to find something along those lines.  One reference type with exactly the same values could in fact be the exact same object, or it could be something wildly different.

Is there a way for me to see this kind of information in C#?  Perhaps some kind of equivalent to the &amp; operator for the watch window or some such?

Uniquely Identifying Reference Types in the Debugger

Summary:

memcpy seems unable to transfer over 2GB/sec on my system in a real or test application. What can I do to get faster memory-to-memory copies?

Full details:

As part of a data capture application (using some specialized hardware), I need to copy about 3 GB/sec from temporary buffers into main memory. To acquire data, I provide the hardware driver with a series of buffers (2MB each). The hardware DMAs data to each buffer, and then notifies my program when each buffer is full. My program empties the buffer (memcpy to another, larger block of RAM), and reposts the processed buffer to the card to be filled again. I am having issues with memcpy moving the data fast enough. It seems that the memory-to-memory copy should be fast enough to support 3GB/sec on the hardware that I am running on. Lavalys EVEREST gives me a 9337MB/sec memory copy benchmark result, but I can&#39;t get anywhere near those speeds with memcpy, even in a simple test program.

I have isolated the performance issue by adding/removing the memcpy call inside the buffer processing code. Without the memcpy, I can run full data rate- about 3GB/sec. With the memcpy enabled, I am limited to about 550Mb/sec (using current compiler).

In order to benchmark memcpy on my system, I&#39;ve written a separate test program that just calls memcpy on some blocks of data. (I&#39;ve posted the code below) I&#39;ve run this both in the compiler/IDE that I&#39;m using (National Instruments CVI) as well as Visual Studio 2010. While I&#39;m not currently using Visual Studio, I am willing to make the switch if it will yield the necessary performance. However, before blindly moving over, I wanted to make sure that it would solve my memcpy performance problems.

Visual C++ 2010: 1900 MB/sec

NI CVI 2009: 550 MB/sec

While I am not surprised that CVI is significantly slower than Visual Studio, I am surprised that the memcpy performance is this low. While I&#39;m not sure if this is directly comparable, this is much lower than the EVEREST benchmark bandwidth. While I don&#39;t need quite that level of performance, a minimum of 3GB/sec is necessary. Surely the standard library implementation can&#39;t be this much worse than whatever EVEREST is using!

What, if anything, can I do to make memcpy faster in this situation?

		__int64 duration = stop.QuadPart - start.QuadPart;

How to increase performance of memcpy

Every time I edit a resource file in VS, it regenerates the corresponding code and sets the class access modifier to internal.  
It&#39;s a pain to Ctrl-F -&gt; ReplaceAll every time I edit the resx. Is there a property/setting so that I can default this to public?


    internal class MyResource {

         internal static global::System.Resources.ResourceManager ResourceManager {...}

    }

I need all those &lt;code&gt;internal&lt;/code&gt; to be &lt;code&gt;public&lt;/code&gt; all the time.

In my project I&#39;m using some third-party libraries. I include them using the references folder in Visual Studio.

But where should I save the DLL files? They are referenced from a path in the file system, but it would be nice if I can include it into the project. But how?


Where to store external DLL files?

I have a form that takes user input and then let the user get connected to the sql server.
This is happening on button click.But where can I set the property Default button so that the user when clicks enter do the work of that button.
