I've used boost::gregorian::date a bit now.
I can see that there are the related months & years & weeks duration types.
I can see how to use known durations to advance a given date.
Qu: But how can I get the difference between two dates in months (or years or weeks) ?
I was hoping to find a function like:
template<typename DURATION>
DURATION date_diff<DURATION>(const date& d1,const date& d2);
There would need to be some handling of rounding too.
I know the standard Major.Minor.Build.Revision but there's several considerations for us that are somewhat unique
-We do internal releases almost daily, occasionally more than once a day.
-Windows Installer doesn't check Revision so that's almost moot for our purposes.
-Major and Minor numbers ideally are only updated for public releases and should be done manually.
-That leaves the Build # that needs to be automatically updated.
-We want internal releases to be able to be performed from any developer's machine so that leaves out using x.x.* in Visual Studio because different numbers could be generated from different machines and each build isn't guaranteed to be larger than the previous.
-We have about 15 or so projects as part of the product so saving the version numbers in SVN isn't ideal since every release we'd have commit all those files.
Given those criteria I can't really come up with a good versioning scheme. The last 2 criteria could be dropped but meeting all of those seems ideal. A date stamp is insufficient because we might do more than one a day, and given the max size of Uint32 (around 64000) (Actually using WiX it complains about numbers higher than Int32.MaxValue) a date/time won't fit.
Columns Words, WordsCount
For each value of Words "x y z" update wordscount with 3 , "a b" with 2, "a b c d" with 4 and etc...
How can I do it with/without .Net program ?
I work in Javascript with integer numbers only (mainly adding numbers and shifting them). I wonder how big they can be without loosing any bits.
For example, how big X can be such that 1 << X will represent 2^X ?
Assign the following 25 scores to a one dimensional int array called "temp"
34,24,78,65,45,100,90,97,56,89,78,98,74,90,98,24,45,76,89,54,12,20,22,55,66
Move the scores to a 2 dimensional int array called "scores" row wise
-- meaning the first 5 scores go into row 0 etc
I am trying to figure out how to manage a Datagrid based on an XML object like this:
<matrix rows="5" columns="5">
<column>
<row>0.5</row>
<row>0.21</row>
</column>
<column>
<row>0.6</row>
<row>0.9</row>
</column>
<column>
<row>0.5</row>
<row>0.5</row>
</column>
<column>
<row>0.8</row>
<row>0.4</row>
</column>
</matrix>
I will need to populate the Datagrid column names based on a different XML object and use the above XML to populate each of the column's rows. I currently am able to create the Datagrid and populate its column headers but I am unsure as to how to how to add the rows for each column. The above XML will be update with new row and column elements added and deleted. This, of course, will be bound to the Datagrid to show updates.
Thanks in advanced for your help.
So, I basically would like to test to see if a string contains a range of alphanumeric characters. It's to be used as a client-side validation and I don't want to prevent users from entering whatever they want. Best to give examples of what should/should not pass validation:
So to be specific, the expression I'm looking for is to test to make sure string contains anywhere from 3 to 10 alphanumeric characters. I'd like to plug into an ASP.NET client side validator.
NOTE: quotes not part of input (but could be!)
" f o o " should pass since there are 3 chars
"f_0_0" should pass
" fo " should not
"F......o......o......b.....a......r" should pass
thx
I have an List<int> which contains 1,2,4,7,9 for example.
I have a range from 0 to 10.
Is there a way to determine what numbers are missing in that sequence?
I thought LINQ might provide an option but I can't see one
In the real world my List could contain 100,000 items so performance is key
I'd like to know whether it's possible to have phone numbers converted
into international format when a call is outgoing.
For instance, if a french user (sorry it's the only format i know i
won't make a mistake :-) try to call with the national format :
01.47.12.34.56 then a method will convert it into international format
like this : +33.1.47.12.34.56
I've looked into the doc of the PhoneNumberUtils but i don't know if
there is a method doing what i want.
We are working on a WebView (not WKWebView, yet) app, are are observing that the app runs extremely slow on iOS 8. The same app runs smooth on lower versions of OS like iOS7 and iOS6. So we tried it in safari on iOS8 and the performance is similar to iOS6 and 7.
The app is filled with images and many are high resolution. While trying to trace the issue (trial and error!) we reduced the sizes and resolutions of the images and the performance improved, but it is still not at par with versions 6 and 7.
We are unable to find any such issues reported elsewhere and are stuck. It would be great if we could get some pointers on this one.
I'm looking to count the dates covered (inclusive) between two DateTimes (not .TotalDays)
For example:
2012-2-1 14:00 to 2012-2-2 23:00 -> 2
2012-2-1 14:00 to 2012-2-2 10:00 -> 2
2012-2-1 14:00 to 2012-2-1 15:00 -> 1
2012-1-1 00:00 to 2012-12-31 23:59 -> 366
I can get this functionality with the code below:
DateTime dt1 = new DateTime(2000,1,2,12,00,00);
DateTime dt2 = new DateTime(2000,1,3,03,00,00);
int count = 0;
for (DateTime date = dt1; date.Date <= dt2.Date; date = date.AddDays(1))
count++;
return count;
Is there a better way?
How can I insert all dates in an year(or more) in a table using sql
My dates table has following structure
dates(date1 date);
Suppose I want to insert dates between "2009-01-01" to "2010-12-31" inclusive.
Is there any sql query for the above?
can any one please let me know, i need to set the "Total Price" value to be in two decimal point value like "56.35". Now its showing more fraction values like "56.3566666". I need it to be format it by musql "SELECT" query.
I want to insert n elements into a map where n is known ahead of time. I do not want memory allocation at each insertion. I want all memory allocation at the beginning. Is there a way to do this? If so, how? Will writing some sort of memory allocator help?
I have a list, with each element being a character vector, of differing lengths
I would like to bind the data as rows, so that the column names 'line up' and if there is extra data then create column and if there is missing data then create NAs
Below is a mock example of the data I am working with
x <- list()
x[[1]] <- letters[seq(2,20,by=2)]
names(x[[1]]) <- LETTERS[c(1:length(x[[1]]))]
x[[2]] <- letters[seq(3,20, by=3)]
names(x[[2]]) <- LETTERS[seq(3,20, by=3)]
x[[3]] <- letters[seq(4,20, by=4)]
names(x[[3]]) <- LETTERS[seq(4,20, by=4)]
The below line would normally be what I would do if I was sure that the format for each element was the same...
do.call(rbind,x)
I was hoping that someone had come up with a nice little solution that matches up the column names and fills in blanks with NAs whilst adding new columns if in the binding process new columns are found...
So I have a question.
I have chatting/IM website that I am working on and I was making a user profile page. I wanted to show how many posts that user had.
Another issue I had earlier was that when I called a certain value it would return a 'Resource #1' type string. But I got that working by using
$totalposts=mysql_query("SELECT * FROM `posts` WHERE Username='" . $username . "'");
$totalposts = mysql_fetch_row($totalposts);
$totalposts = $totalposts[0];
But that just returns the last postID of the most recent post. I thought that mysql_num_rows would work. But this code returns an error (example with numbers):
29: $totalposts=mysql_query("SELECT * FROM `posts` WHERE Username='" . $username . "'");
30: $totalposts = mysql_num_rows($totalposts);
31: $totalposts =mysql_fetch_row($totalposts);
32: $totalposts = $totalposts[0];
That returns this error:
Warning: mysql_fetch_row(): supplied argument is not a valid MySQL result resource in /home/a9091503/public_html/im/user.php on line 31
Thanks guys. :) I hope you can figure this out. :D
Best to use an example to describe the problem. Lets say I have a decimal value 100.227273.
100.227273 * X = Y
I need to find the smallest possible integer X that gives integer Y.
I am looking for a one liner to pull out the first comment block in any file. The comment blocks look like this:

I've been trying to play with sed, but just can't get it to work right. Help?
Hi,
I am trying to display country codes(+91, +60, +01) in the combobox. Although the dataprovider(array) contains + sign but is removed. I am not getting how to show it with sign.
<mx:Array id="countryArray">
<mx:Object label="India" data="+91" />
<mx:Object label="Malaysia" data="+60" />
<mx:Object label="Usa" data="+01" />
</mx:Array>
Is this the problem with dataprovider? How can I treate them as text not numbers?
Please help.
Thanks in advance.
Hi All,
I got one problem while doing one TAPI application based project in C#. I'm using ITAPI3.dll
My problem is.. i'm not getting incoming call information. To get the incoming call information, i'm using the getcallinfo function, but it is showing empty message.
I'm working on a large ERP project which has database model with about 2100 tables. With "only" 500 tables mapped with Hibernate, application deployed on the web server takes about 3GB of working memory.
Is there any way to reduce Hibernate's metamodel memory footprint when using that many tables in one persistence unit? Or should I just give up on ORMs and go with plain old JDBC (or even jOOQ)?
Right now I'm using Hibernate 4.1.8, Spring 3.1.3, JBoss AS 7.1 and working with MSSQL database.
Edit:
JavaMelody memory histogram output - with 2000 generated test tables that are a bit smaller in scope from the original db model (hence 'only' 1.3GB of spent memory)
Is there a way to set a limit on how many menu items users can add to Primary Links menu? I'm working on a Drupal site and I have a horizontal primary links nav bar. There is only room for no more than 7-8 links in the nav bar. I don't want the future maintainer of the site to add more than 8 items to the menu. Is there a way I can set a limit on that? Some module or override function?
Thanks,
