[0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1]
Is there an easier (or built-in) way to do this than the following:
function M = stairstep(v)
M = zeros(length(v),max(v));
v2 = [0 v];
for i = 1:length(v)
M(i,(v2(i)+1):v2(i+1)) = 1;

E.g. if it were a stock chart application, I would want my link to contain the symbol and then have the GWT app read that and make a request to some stock service. E.g. http://myapp/gwt/StockChart?symbol=GOOG would be the link to my StockChart GWT app and it would make a request to my stock info web service for the GOOG stock.
So far, I've been using the server-side code to add Javascript variables to the page and then I've read those variables using JSNI (JavaScript Native Interface).
For example:
In the host HTML:
<script type="text/javascript">
var stockSymbol = '<%= request.getParameter("symbol") %>';
</script>
In the GWT code:
public static native String getSymbol() /*-{
return $wnd.stockSymbol;
}-*/;
(Although this code is based on real code that works, I've modified it for this question so I might have goofed somewhere)
However, this doesn't always work well in hosted mode (especially with arrays) and since JSNI wasn't around in version 1.4 and previous, I'm guessing there's another/better way. | gwt | null | null | null | null | null | open | Best practice for parameterizing GWT app?

<pre>
/* Force a compilation error if condition is true */
#define BUILD_BUG_ON(condition) ((void)sizeof(char[1 - 2*!!(condition)]))
</pre>
So, in your code, if you have some structure which must be, say a multiple of 8 bytes in size, maybe because of some hardware constraints, you can do:
<pre>
BUILD_BUG_ON((sizeof(struct mystruct) % 8) != 0);
</pre>
and it won't compile unless the size of struct mystruct is a multiple of 8, and if it is a multiple of 8, no runtime code is generated at all.
Another trick I know is from the book "Graphics Gems" which allows a single header file to both declare and initialize variables in one module while in other modules using that module, merely declare them as externs.
<pre>
#ifdef DEFINE_MYHEADER_GLOBALS
#define GLOBAL
#define INIT(x, y) (x) = (y)
#else
#define GLOBAL extern
#define INIT(x, y)
#endif
GLOBAL int INIT(x, 0);
GLOBAL int somefunc(int a, int b);
</pre>
With that, the code which defines x and somefunc does:
<pre>
#define DEFINE_MYHEADER_GLOBALS
#include "the_above_header_file.h"
</pre>
while code that's merely using x and somefunc() does:
<pre>
#include "the_above_header_file.h"
</pre>
So you get one header file that declares both instances of globals and function prototypes where they are needed, and the corresponding extern declarations.
So, what are your favorite C programming tricks along those lines?

I was asking myself how to split my SQL records within groups of letters, like this example:
<b>A-----</b><br>
Andrew<br>
Arnold<br>
<b>B-----</b><br>
Bernard<br>
<b>C-----</b><br>
Carol<br>
Christine<br>
Costantine<br>
etc.
With few PHP rows I found a pretty simple solution.<br>-----------------------------------------------------------------<br>
*// keep track of previous letter<br>*
$prevLetter = '';
foreach($yourarray as $row) {
$letter = substr($row, 0,1);<br><br>
if($letter != $prevLetter) {<br>
$prevLetter = $letter;<br>
echo $letter
<br>;}
}
Hope you'll find this helpful in your projects!
Luke :)

So far, we have only gone over the very basics of C++. So basically, we know variables, assignment, and basic casting.
In the book I am having trouble with this portion of the problem:
* prompt the user to input a decimal number
* Convert that number to the **nearest** integer and print it to the screen
So I have the trivial code:
double n;
cout<<"Number: ";
cin >> n;
cout <<endl<<static_cast<int>(n)<<endl;
But I realized this does not work for me. It will always truncate the decimal so that 1.9 -> 1 rather than the expected 1.9 -> 2
How do I fix this using only what I "know"? (as in, without round() or if statements and such)
Is this a standards compliance problem? At school I *thought* I had something similar working with Visual C++ 2005 on Windows XP 32 bit, but now I'm at my home trying to do the same thing and it's not working. My home compiler is gcc 3.3.5 on OpenBSD 64bit. Or could this be a typo in the book? | c++ | homework | casting | null | null | null | open | Rounding with static_cast<int> ?

When the response comes back it has a refresh token, access token, expired_at, etc. I am then able to make API requests with the access code. But once that access code expires (after an hour), I believe I need to use the refresh token to get a new access token, correct?
But when I try to do that I get this:
@client.authorization.fetch_access_token!
ArgumentError Exception: Missing authorization code.
I see that in my @client object, @code=nil. I'm assuming that's what needs to be set, but I don't get a 'code' property returned from my initial request.
How do I get that code, or if I don't need it, what am I doing wrong?
Thanks!

then from the admin>index.php page i have created a link that goes to a page called 'create_hot_listing.php' which has just 1 php block for session start and to check that the manager is correctly logged in! in that i have a very simple form with a field for 'deal_name' and a text area for 'details' (which im going to add the tinyMCE wysiwyg form,) and a form action called 'hotdeal_parse.php'
Now for my parse script

My own hunch is that Excel needed to give people a way to get ranges from string addresses, and to get the value of named formulas, and just opening a portal to the expression evaluator was the easiest way. But of course you don't need the ability to evaluate arbitrary expressions just to do that. <code>Application.Evaluate</code> seems kind of...unfinished.

For some reason though when my program searches for non white pixels, its finding the ones i just set to white.
Why is it saying its not white when it is? I have an image that gets cropped and is saved to my hard drive. So im able to view the area it says isnt white, but when i open the image, its completely white as can be. So I'm at a lose as to why this isn't working. The program stops on the same pixel every time. It says the R value is 238 and I know that pixel was set to white because i stepped through the debugger and watched the pixel value go into the bmp.setpixal method.
This is the code for the "blanking" method:
void blankArea(int x, int y, int width, int height)
{
for (int i = y; i <= height+y; ++i)
for (int t = x; t <= width+x; ++t)
{
if (t == w)
break;
bmp.SetPixel(t, i, Color.White);
}
}
this is the code that says that pixel isn't white:
bool allWhiteColumn (int col)
{
for (int i = 5; i < h; ++i)
if (bmp.GetPixel(col - 1, i).R < 248 && bmp.GetPixel(col - 1, i).G < 248)
{

************** JIT Debugging ************** To enable just-in-time (JIT) debugging, the .config file for this application or computer
(machine.config) must have the jitDebugging value set in the
system.windows.forms section. The application must also be compiled
with debugging enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration> When JIT debugging is enabled, any unhandled exception will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box. and also to mention in

I have a TextBox control with OnTextChanged handler. The event handler is working fine most of the time, but when the user changed the text and press Enter in FF, the OnTextChanged event is called twice. I observed the problem in Firebug that the first request is actually canceled because of the second event.
So my question is, what's the best way to properly handle OnTextChanged event so that hitting enter in the textbox doesn't trigger double postback.

In my SSIS package I have a data flow task.
There's several different transforms, merges and conversions that happen in here.
At the end of the dataflow task, there is two datasets, one that contains two numbers that need to be compared, and another dataset that contains a bunch of records.
Idealy, I would like to have these passed onto a whole new data flow task (seperate sequence container) where I can do some validation work on it and seperate the logic.
I cant for the life of me figure out how to do it. Iv tried looking into scripting and storing the datasets as variables, but im not sure this is the right way to do it.
The next step is to export the large dataset as a spreadsheet, but before this happens i need to compare the two numbers from the other dataset and ensure they're correct.
can anyone suggest a solution for me ?
Cheers
