Is there anything that stops the DateTime AddDays() method that doesn't run within a while loop. I have this simple bit of code;
DateTime last_day = monthCalendar2.SelectionRange.End;
DateTime first_day = new DateTime(year, month, day);
//Insert dates into vector
while (first_day != last_day)
{
dates.Add(first_day);
first_day.AddDays(1);
}
I step through the program and first_day never changes, anyone know why?!

This (similar version from old link) works in SQL Server 2008, however, Oracle is giving me trouble:
MERGE INTO wdm_test
USING ( select '10000000000000000000000000000000' Guid from DUAL ) val
ON ( wdm_test.Guid = val.Guid )
WHEN MATCHED THEN UPDATE SET test_column = null
WHEN NOT MATCHED THEN
INSERT (Guid, test_column)
VALUES ('10000000000000000000000000000000', null)
OUTPUT $action;
SQL Error: ORA-00933: SQL command not properly ended
Does Oracle not support OUTPUT $action;? If not, is there an alternative?
I'm running windows xp and I've got MiniMagick and ImageMagick installed (latest versions). I'm now using the console to test out that everything works. Using the ms command prompt image magick works no problem. I'm testing this by using the identify command. Now, when I try to use MiniMagick from the console by entering
image = MiniMagick::Image.new('image.jpg')
It returns
MiniMagickError, "ImageMagick command ("identify \"input.jpg\"") failed: {:status_code = #"'identify' is not recognized as an internal or external command,\noperable program or batch file.\n"}
Can anybody help?
I created an .png image from a video using ffmpeg tool and i want to how to insert that image into the db which has a blob field and also i want to know how can i recollect that image from the db to display as a image again?
I am looking for a best practice while uploading images to amazon s3 server and serving from there.
We need four different sizes of an image. So just after image upload we convert the image and scale in 4 different widths and heights. And then we send them to the amazon s3 using official php api.
// ...
// image conversions, bucket setting, s3 initialization etc.
$sizes= array("", "48", "64", "128");
foreach($sizes as $size) {
$filename = $upload_path.$dest_file.$size.$ext;
$s3->batch()->create_object($bucket, , array(
'fileUpload' => $filename,
'acl' => AmazonS3::ACL_PUBLIC,
));
}
But for a 1M image the client sometimes wait up to 30 seconds which is a very long time.
Instead of sending images immediately to S3, it may be better to add them to a job queue. But the user should see the uploaded image immediately.
Hi,
I am doing a project in which i require btree or b+tree data structure. but its not an important part of project. it would take my time to write a code for it. I googled it but didn't get anything....
So, can anyone provide java code for btree or b+tree implementation (with insert, delete, search algorithms)??????
it should accept string as input and form btree or b+tree of these string.

I have a domain class that can have a nullable one-to-many field. When using dynamic scaffolding, the view will insert a value from the foreign table (usually the first one in the list) even if i don't want to set this field.
Does GetVolumeNameForVolumeMountPoint() return the GUID of a volume in c++?
GetVolumeNameForVolumeMmountPoint()
{
LPCTSTR lpszvolumeMountPoint,
LPTSTR lpszVolumeName,
DWORDcchBufferLength,
}
I mean if I am using a removeable disk. will the lpszVolumeName remained the same on the same computer?
Does it return a certain ID for a certain volume everytime I insert the disk on my computer' USBport.
And Make sure different disk's volumes will get different result?
Many Thanks!
I have a table with 42 million records. 32 million have a null value and I would like to generate a new guid for each one. Should I do this in batches?
Also, going forward, I would like a new guid added to the field on the insert of a new record. What is the best way to do this?
The field is not the primary key, which is an auto-incrementing integer.
it cause from i insert UIViewController to subview of UITabBarController.
once i want to set UIViewController shouldAutorotateToInterfaceOrientation and it not possible because it will call only in UITabBarController.
how can i forward message from UITabBarController to call shouldAutorotateToInterfaceOrientation of each UIViewController instead of call UITabBarController only?
I am exploring a possibility to write a kind of a notebook analogue that would reproduce the look and feel of using a traditional notebook, but with the added benefit of customizing the page in ways you can't do on paper - ask the program to lay ruled paper here, grid paper there, paste an image, insert a recording from the built-in camera, try to do handwriting recognition on the tablet input, insert some latex for neat formulas and so on. I'm pretty interested in developing it just to see if writing notes on computer can come anywhere close to the comfort plain paper + pencil offer (hard to do IMO) and can always turn it in as a university C++ project, so double gain there.
Coming from the type of project there are certain requirements for the user interface:
the user will be able to zoom, move and rotate the notebook as he wishes and I think it's pretty sensible delegate it to OpenGL, so the prospective GUI needs to work well with OGL (preferably being rendered in it)
the interface should be navigable with as little of keyboard input as user wishes (incorporating some sort of gestures maybe) up to limiting the keyboard keys as modifiers to the pen movements and taps; this includes tablet and possible multitouch support
the interface should keep out of the way where not needed and come up where needed and be easily layerable
the notebook sheet itself will be a container for objects representing the notebook blurbs, so it would be nice if the GUI would be able to overlay some frames over the exact parts of the OpenGL-drawn sheet to signify what can be done with given part (like moving, rotating, deleting, copying, editing etc.) and it's extents
In terms of interface it's probably going to end up similar to Alias' Sketch Book Pro: [picture][http://1.bp.blogspot.com/_GGxlzvZW-CY/SeKYA_oBdSI/AAAAAAAAErE/J6A0kyXiuqA/s400/Autodesk_Alias_SketchBook_Pro_2.jpg]
As far as toolkits go I'm considering Qt and nui, but I'm not really aware how well would they match up the requirements and how well would they handle such an application.
As far as I know you can somehow coerce Qt into doing widget drawing with OpenGL, but on the other hand I heard voices it's slot-signal framework isn't exactly optimal and requires it's own preprocessor and I don't know how hard would be to do all the custom widgets I would need (say color-wheel, ruler, blurb frames, blurb selection, tablet-targeted pop-up menu etc.) in the constraints of Qt. Also quite a few Qt programs I've had on my machine seemed really sluggish, but it may be attributed to me having old PC or programmers using Qt suboptimally rather to the framework itself.
As for [nui][http://www.libnui.net/] I know it's also cross-platform and all of the basic things you would require of a GUI toolkit and what is the biggest plus it is OpenGL-enabled from the start, but I don't know how it is with custom widgets and other facets and it certainly has smaller userbase and less elaborate documentation than Qt.
The question goes as this:
Does any of these toolkits fulfill (preferably all of) the requirements or there is a well fitting toolkit I haven't come across or maybe I should just roll up my sleeves, get SFML (or maybe Clutter would be more suited to this?) and something like FastDelegates or libsigc++ and program the GUI framework from the ground up myself?
I would be very glad if anyone had experience with a similar GUI project and can offer some comments on how well these toolkits hold up or is it worthwhile to pursue own GUI toolkit in this case.
Sorry for longwindedness, duh.

How could i fix this? Thanks.
I want to store the last 3 items in an MySQL database in an efficient way. So when the 4th item is stored the first should be deleted.
The way I do this not is first run a query getting the items. Than check what I should do then insert/delete.
There has to be a better way to do this. Any suggestions?
I have a requirement to copy whatever data is getting inserted or updated to a log table to show who updated and when. I was thinking of using triggers for the same. The reason being the insert needed not be only stored procedure but can also be packages. Can I use extended events for the same ?.
Hello All,
I dont know how to copy table data from
one server - database - table
TO
other sever - database - table.
If it is with in the same server and different databases, i have used the following
SELECT * INTO DB1..TBL1 FROM DB2..TBL1 (to copy with table structure and data)
INSERT INTO DB1..TBL1(F1, F2) SELECT F1, F2 FROM DB2..TBL1 (copy only data)
Now my question is copy the data from SERVER1 -- DB1-- TBL1 to SERVER2 -- DB2 --TBL2
Thanks in advance!
Hello,
In my tables, i have selected id column to be of type int (4 bytes). The answer i want to know is how will any database handle it once it's limits are reached? Will the database refuse to insert any more records in table? or what exactly will happen? Also how should i tackle this type of problem (if the database doesn't handle it by itself)?
Using logparser to import IIS logs to a db results in one column that has the date value and a second field for time:
2010-05-25 00:00:00.000 2010-01-01 11:11:58.000
I'd like to code an INSERT AFTER trigger that combines the 2 fields.
