I just knew about one more type of keyboard layout and made a research on this from Wikipedia (http://en.wikipedia.org/wiki/AZERTY[^])
But wouldn't such diversified standards be daunting for frequent business travellers?

Hi,
there are a lot of different keyboard layouts, in Europe there is a specific one
for half of the countries. Belgium and France have AZERTY, Germany has QWERTZU, etc.
Major reason is the existence and usage of accented characters (needed all the time
in French, Spanish, etc); the Netherlands have a 27th letter; etc.
Frequent business travellers are advised to carry their own laptop!
Only one keyboard really suits programmers if you ask me, and that's QWERTY,
with unshifted digits (AZERTY has them shifted!), easily accessible square brackets, etc.

hi friend's
yesterday i said a question about how to write a program by parallel programming method.
and i recieve many replies from my friend's.
but i am confusing still...
i read a bool that say me to work with multi-pascal for learning parallel programming. in this software that simulate the multi proccessor OS, allow you to change your code from sequential into parallel code.such as use forall instead of for command.
but this software just is a simulate software and do not work really on a multi proccessor OS.so i say my question again:
i have a loop in my program with for statement and this loop run for 1000,000 times. i want to create 10 process that each process perform 100,000 action.so please guide me to do it.
thank you very mutch

I believe parallel programming libraries use multiple or multi-core chips. Currently, the .NET languages have multi-threading code which is not adequate for parallel programming. The Professional VS version of native C++ has a library called OpenMP to do parallel programming: http://msdn2.microsoft.com/en-us/library/tt15eb9t(VS.80).aspx[^].

I am creating a Log On page where I am trying to extract UserName and Password from a StoredProcedure. This code below is trying to return a boolean value.
But no matter what UserName and Password I enter I always get access to the FileManager.aspx file. It gives access to anybody who logson. Where should I change the code to make it work??
try
{
sqlconSource.Open();
if (sqlcmdSource.ExecuteScalar().ToString() == "0")
Response.Redirect("AccessDenied.aspx");
}
catch
{
}
finally
{
Response.Redirect("FileManager.aspx");
sqlconSource.Close();
}
}

Not sure what the query is in your stored procedure, but maybe this snippet from MSDN will shed some light for you...
SqlCommand.ExecuteScalar executes the query, and returns the first column of the first row in the result set returned by the query. Additional columns or rows are ignored.<br />
<br /> So, the only way you will be redirected to AccessDenied.aspx is if the first column in the first row of the results provided by your stored procedure evaluates to "0".

Hi everyone, i need a regular expression that can extract the name and content section from each class in a css file...
.Data1{color:#000000}
.Data2{ color:#111111
}
.Data3{
color:#222222
}
the regexp should extract :
.Data1 => color:#000000
.Data2 => color:#111111
.Data3 => color:#222222
Without the { or } chars
Ive tried but nothing seems to work....im only be able to parse .Data1{color:#000000} using this expression (\.(.+){(.+)})
Thanks in advance.

Allow for line breaks inside the brackets. Also you need to make your quantifiers non-greedy, or you will be cathing everything in the first match.
(\.(.+?){\s*(.+?)\s*})
If the content contains line breaks, a period doesn't match that.
(\.(.+?){\s*([\w\W]+?)\s*})

How big is a bool value?
For example an int is 4byes...
Common sense tells me its just one bit, either a 0 or a 1... but id like to know for sure. Thanks ^^

bool is also 4 bytes

No, it's one byte.

The size of a bool is one byte.
How much memory that is needed to store a bool depends on where you store it. Variables in a class or struct are generally aligned on a four byte boundary, but if you have bools that are declared next to each other, they are aligned inside the same four byte boundary.
Example:
struct A12ByteStruct {
bool test1;
int test2; bool test3;
}
struct An8ByteStruct {
bool test1;
bool test3;
int test2; }

Wouldn't the compiler be smart enough to recognize this and align the bools inside the same boundary?
|
|

One would think so, but appearently it doesn't. Perhaps it will in future versions.

Well, it shouldn't rearrange the fields.
|
|
|
|
|
Hmmm...I thought that in the managed world you weren't guaranteed the order in a struct. That is why most structs used for P/Invoke calls needs the [StructLayout(LayoutKind.Sequential)] attribute so it told the compiler not to rearrange the fields.
|
|
|
|

I concur.
The order is not specified, unless you use LayoutKind.Sequential or explicit offsets.
AFAIK the padding is also not specified.
Nevertheless there must be some mechanism to let different CLR languages work together
on the same structs. Do they all use the same conventions, or is the JIT taking into
account some available metadata ?

Apparently, I was only partially correct. According to the MSDN docs:The members of the object are laid out sequentially, in the order in which they appear when exported to unmanaged memory. The members are laid out according to the packing specified in StructLayoutAttribute.Pack, and can be noncontiguous.
And the docs for StuctLayoutAttribute.Pack say:This field indicates the packing size that should be used when the LayoutKind.Sequential value is specified. The value of Pack must be 0, 1, 2, 4, 8, 16, 32, 64, or 128. A value of 0 indicates that the packing alignment is set to the default for the current platform.
The default packing size is 8, except for unmanaged structures that typically have a default packing size of 4. So, it sounds like as long as the struct stays inside managed code, the fields are packed along an 8 byte boundary, but if the struct is exported to unmanaged code and has LayoutKind.Sequential set it is exported in the order in which they appear in the definition.
