How can I calculate the count of each row and they are grouped in each mth?

hi, I need help on a database question. How can I count the number of record grouped by the last 12 months? I don't know any way to iterate the month one by one so that it return a table like this:
table_item
id item
1 A
2 B
3 C
4 D
table_record
item date
A 2006-01-01
A 2006-01-01
A 2006-01-01
B 2006-02-01
A 2006-03-01
C 2006-04-01
A 2006-04-01
D 2006-05-01
A 2006-05-01
A 2006-12-01
and I need a query to output following table:
item_count_in_2006
item 06-01 06-02 06-03 06-04 06-05 06-06 06-07 06-08 06-09 06-10 06-11 06-12
A 3 1 1
B 1
C 1
D 1
I tried so many way to do it.. I think SQL can't even product a table like that. Please give me some comments.
Thanks!

Hi, how can i break the value for a row and column once i have converted the image to the array???????

Hi, I would like to know how can i break the value for a row and column once i have converted the image to the array. I wanted to make some modification on the element of the array at a certain position. how can i do that?
At the moment (as per attachhment), the value of the new row and column will be inserted by the user. But now, I want to do some coding that will automatically insert the new value of the row and the column ( I will use the formula node for the programming). But the question now, I don't know how to split the row and the column. Is it the value of i in the 'for loop'? I've tried to link the 'i' to the input of the 'replace subset array icon' , but i'm unable to do it as i got some error.
Please help me!
For your information, I'm using LABView 7.0.

Hi,
Thanks for your reply.Sorry for the confusion.
I manage to change the array element by changing the row and column value. But, what i want is to allow the program to change the array element at a specified row and column value, where the new value is generated automatically by the program.
Atatched is the diagram. I've detailed out the program . you may refer to the comments in the formula node. There are 2 arrays going into the loop. If a >3, then the program will switch to b, where if b =0, then the program will check on the value of the next element which is in the same row with b but in the next column. But if b =45, another set of checking will be done at a dufferent value of row and column.
I hope that I have made the problem clear. Sorry if it is still confusing.
Hope you can help me. Thank you!!!!

How can I get the keyboard commands to do what they are spozed to do?

Some keyboard commands work OK. But some do unexpected things. For example, when I press the F11 key in InDesign, the page parts like a curtain opening leaving the empty desktop; the same key toggles the page back again. What the F11 key should do is open the Paragraph Style palette. Strangely, the "single-digit" commands -- F5, F6, etc. work OK. But those with 2 digits -- F11, F12 -- do not. (This is a G5 iMac with the original keyboard.) How can I fix this?
iMac G5 Mac OS X (10.4)

That's Apple's Exposé at work. To change the keys for that, go into System Preferences, then Dashbord & Exposé (top row, second in). You can change the keys, disable it, or assign corners of the screen to do it.
Conversely, you could go into InDesign -> Edit -> Keyboard Shortcuts and change the Paragraph style pallete (gotta dig for that) command to Command f-keys.
I'd actually do the second one, as easy access to Exposé just rules - once you get used to it, it will be second nature. It's especially helpful when you have a pile of Photoshop and InDesign windows open, and need to find one particular one, or need to see something on the desktop.

How can I calculate the request time ?

I have two apple id's because my hotmail account is no longer active. How can I delete the old one and use or update the new one? Every time I try it won't allow me and now my iPad thinks there are two accounts and they are arguing with each other. Help!

I have two apple id's because my hotmail account is no longer active. How can I delete the old one and use or update the new one? Every time I try it won't allow me and now my iPad thinks there are two accounts and they are arguing with each other. Help!

You can't merge accounts or copy content to a different account, so anything that you bought or downloaded via the old account is tied to that account - so any updates that those apps get you will only be able to download via that account. You can change which account is logged in on the iPad via Settings > Store

How can I get the photos on my pc onto my Macbook without emailing each one individually to myself?

How can I get the photos on my pc onto my Macbook without emailing each one individually to myself?

Welcome to Apple Support Communities.
Copy them from your PC to a flash drive or an external drive, then open iPhoto and select Import to Library.
Depending on your settings, iPhoto might open automatically and ask if you want to import them when the device (camera or flash drive or external drive) containing the images is connected.
At the end of the import, iPhoto will ask if you want to delete or keep the photos on the other device. Keep until you're absolutely certain all images are imported correctly and you've viewed them in iPhoto. It's always nice to have a backup.

How can i calculate the average in java

how can i calculate the avergae mark out of two marks for instance in like exam mark out
of two other ones
thanks for considering this message

Average or Mean:
sum_of_N/N
Here N is the number of marks.
sum_of_N is the total sum of n(all marks added together)
public int average(int[] marks) {
int sum;
sum = 0;
for(int i=0;i < marks.length;i++) {
sum=marks[i]+sum; // keep adding to the total
return average = sum/marks.length;
// warning- using an int here can be a pitfall(we could have a decimal outcome).

How can I calculate the waveform integral in a defined time interval?

Hi:
I need your help. How can I calculate the waveform integral in a defined time interval? For example: from "0" to "2pi"?!
Thanks.

Hello Clecio,
You might want to try the Integral x(t) VI. The documentation for this VI notes:
Performs the discrete integration of the sampled signal X. Integral x(t) calculates a definite integral. The value of the output array at any value x is the area under the curve of the input array between 0 and x.
You would pass the samples of the waveform that fall between your particular window, then pass 1/number of samples for the d(t) parameter.
Hope that helps.

How can I calculate the total time in java?

Hello!
I need to calculate the total time!
For example I have start time:
          Format formatter1;
          Date date1 = new Date();
          formatter1 = new SimpleDateFormat("hh:mm:ss");
          String startTime = formatter1.format(date1);
          //startTime = "14:20:40";
And I have finish time:
          Format formatter2;
          Date date2 = new Date();
          formatter2 = new SimpleDateFormat("hh:mm:ss");
          String finishTime = formatter2.format(date2);
          //finishTime = "08:30:55";
So, after manually calculating, I get total time: "18:10:15"
How can I calculate the total time in java? (Using formatter1 and formatter2 I suppose)
What I need is to print "total 18:10:15"
Thanks!

I did the following but, I think something is wrong here:
I defined before: Date date1 = new Date(); Date date2 = new Date();
And it should be exactly 5 seconds between them.
I found delta between date1 and date2:
Format formatter = new SimpleDateFormat("HH:mm:ss");
          long timeInMilliFromStart = date1.getTime() - date2.getTime() ;
          Date date3 = new Date(timeInMilliFromStart);
          String timeInSecFromStart = formatter.format(date3);
and I get always
//timeInSecFromStart = 02:00:05
But it should be exactly 00:00:05.
What can be a problem?Because, like I said, a Date measure an instant in time, not a duration. So when you have 5000 ms, and you turn that into a Date, that means 5 sec. after the epoch, which works out to 1/1/1970 00:00:05.000 GMT.
As I mentioned, if you're not currently in GMT, then you have to set the TZ of the DateFormat to GMT. Right now, it's showing you the time in your TZ. If you included the date in your SimpleDateFormat, you'd see either 1/1/1970 or 12/31/1969, depending on which TZ you're in.
Bottom line: You're trying to use these classes in a way they're not meant for, and while you can get the results you want for a limited set of inputs if you understand what these classes do and how to work with that, it's a brittle approach and comes with all kinds of caveats.

Text on path: How can I calculate the text length?

Hi
I have a text on path (spline item). Now I need the length of this text and the length of the spline item.
I try to calculate the text length using IWaxLine::GetWidth(), but this is always 0.
- How can I calculate the length of this text?
- How can I calculate the length of the spline item?
Thanks
Hans

It would be interesting if you could describe the purpose of your "length", but I don't have an answer anyway. Would the bounding box be sufficient?
Considering that TOP may be combined with arbitrary spline paths, this could become an exercise in higher math. I haven't yet encountered a function that returns the mathematical length of such a spline.
Otherwise it could be solved if you iterate and sum up the relevant points of the bounding box (ascender, descender, baseline?) of individual glyphs.
Be warned that the whole TOP looks alien, as if it were a transplant from a different program. Experience also shows that documented and actually used interfaces / commands are completely different animals ...

How can I change the counter symbols for the slideshow templates in Muse?

How can I change the counter symbols for the slideshow templates in Muse? Currently they are obviously normal text characters. So, how can I change them to filled circles, for example?

Hi Aish,
Thank you very much. This was very helpful. I am still new to Muse and try to find my way through all the features and possibilities. I like it very much so far.
Does Muse support ‘liquid” design as well?
Thank you !
Best regards,

I recently had to completely restore my laptop, so I lost the music on my itunes. It's still on my iphone, but how can I keep the music I already have and continue to add more music from the newly set up itunes again? Is there actually a way to do this? I can't help but wonder what the stupid icloud is for if my music is still somewhere in the 'cloud' but it's zero help for restoring music when it's lost on a computer....any help even a site that get's around apple would be great!

It has always been very basic to always maintain a backup copy of your computer.
Have you failed to do this?
If so, not good, you can transfer itunes purchases from the iphone to your computer. File>Devices>Transfer Purchases
You can also redownload some itunes purchases in some countries:
