I want to do the following dynamically
Generate numbers from 1 to 100 and then select 25 random numbers from it and display it in a console. Any easy way to do so?
Say I want a function that takes two floats (x and y), and I want to compare them using not their float representation but rather their bitwise representation as a 32-bit unsigned int. That is, a number like -495.5 has bit representation 0b11000011111001011100000000000000 or 0xC3E5C000 as a float, and I have an unsigned int with the same bit representation (corresponding to a decimal value 3286614016, which I don't care about). Is there any easy way for me to perform an operation like <= on these floats using only the information contained in their respective unsigned int counterparts?
It is easy to display the status of a Windows service or to control it (start/stop) from a GUI application but the question if how about receiving/sending notifications from the service? Like: service telling to the user monitoring it that it needs attention.
Please consider that you can have several controllers started at any time in a multi-user environment.
Do you know an example(open source) for this kind of communication?
Extra points for a platform independent solution :)
I want to execute a powershell using the .net Powershell SDK. I have this working fine.
Before I execute it I want to check that the script has been signed by my code signing certificate - this is easy enough to do from within powershell itself using Get-AuthenticodeSignature but I would like to do this in code before choosing to execute this script.
Is there an easy way to convert an XMLType to a User Defined Type? I can convert the UDT to XMLType using the below.
select SYS_XMLGEN(pUDT) into param2 from dual;
I can't though, is find a function that takes that and turns it back into that UDT using the same mappings the SYS_XMLGEN used.
Is there an easy way to calculate the size of an entity stored in App Engine? I would like to know how close a particular entity is to hitting the 1 MB upper limit on entity size.
What methods are there to get JPQL to match similar strings?
By similar I mean:
Contains: search string is found within the string of the matches entity
Case-insensitive
Small mispellings: e.g. "arow" matches "arrow"
I suspect the first two will be easy, however, I would appreciate help with the last one
Thank you
This is probably an easy one, but is the right way to calculate volume for a sphere in c++. My getArea() seems to be right, but when I call getVolume() it doesn't output the right amount. With a sphere of radius = 1, it gives me the answer of pi, which is incorrect:
double Sphere::getArea() const
{
return 4 * Shape::pi * pow(getZ(), 2);
}
double Sphere::getVolume() const
{
return (4 / 3) * Shape::pi * pow(getZ(), 3);
}
Is there an easy way to order MySQL results respectively by WHERE id IN (...) clause?
Example:
SELECT * FROM articles WHERE articles.id IN (4, 2, 5, 9, 3)
to return
Article with id = 4
Article with id = 2
Article with id = 5
Article with id = 9
Article with id = 3
and also
SELECT * FROM articles WHERE articles.id IN (4, 2, 5, 9, 3) LIMIT 2,2
to return
Article with id = 5
Article with id = 9
Some modules have easy install, others need to be copied in site package but some of them really doesn't work.
And i need to import 3 module(libraries) but when i run program.py with python Sheel ...apear no module named ....(so it's not installed correctly)?!
I'm trying to debug a webpart installed on a client's SharePoint instance. I wanted a quick and easy logging feature, so I thought of writing messages to a text file in the temp directory. SharePoint doesn't seem to like it, so what are my options?
Hello
For example
MYCLASS[] myclass = new MYCLASS[10];
Now myclass array is all null array but i want to have default constructed Array .I know that i can write loops for set default constructed but i am looking for more easy and simple way.
at the moment im loading xml and i am getting error:
System.Xml.XmlException: ' ',
hexadecimal value 0x17, is an invalid
character. Line 2762, position 16.
it is easy to fix. just open xml and remove the character.
but I need to know is it possible to load xml even with invalid characters and use it for parsing.
and is there any downside?
I'm trying to implement sub surface scattering at isosurfaces and looked up how a BSDF works mathematically.
Implementing the reflective and diffuse part seems to be quite easy as i just have to evaluate phong at the isosurface intersection, but how do you I apply the transmissive part of the BSDF? In what way do i have to modify the ray direction.
Any pointers to a practical implementation are welcome.
Thanks and So long!
I'm not much into audio engineering, so please be easy on me. I'm receiving an audio file as input, and need to detect whether the speaker is male or female. Any ideas how to go about doing this?
I'm using php, but am open to using other languages, and don't mind learning a little bit of sound theory as long as the time is proportionate to the task.
Is there an easy way of programmatically checking if a serial COM port is already open/being used?
Normally I would use:
try
{
// open port
}
catch (Exception ex)
{
// handle the exception
}
However, I would like to programatically check so I can attempt to use another COM port or some such.
By security I mean that encoded string is indistinguishable from random noise and is different on every encryption of the same text so it is impossible to make a guess on encryption algorithm used or do any dictionary attack on the encoded text.
Second: output string length does not correspond to the input string length in easy way, so it is not possible of make guessing on that account.
Third: it is possible to verify that the provided password is incorrect so the decoding function could return false instead of supposedly decoded random string.
Hello, is there any easy way to port Lua code to C#?
The biggest problem would probably be to port tables neatly in some dictionaries.
And to prevent any misunderstanding: no I cannot use embedded Lua in my program.
In Windows Mobile (5,6) you can have different sound volume settings. The volume itself is easy, but how do I differ between the two silent settings?
There is one volume setting "vibration only" and one "no sound, no vibration at all".
Since my program is using vibration, I'd like to know if windows mobile is set to "no vibration at all", so I don't annoy the user when he wants his phone to be absolutely silent.
jQuery made javascript so easy for me, I was able to get up and running in a couple of hours doing most tasks.
Which PHP framework has similar ease of use and rapid development/write less ability? Or am I stuck basically learning a new language no matter what framework I decide on?
Is there an easy way to detect if you're running in the context of a Visual Studio Test as opposed to debug or release?
Here's the scenario - we have a factory class that we use heavily throughout our existing codebase, and I figured instead of refactoring it out in each class so we can substitute the default factory with one that would return mock/fake objects, I could add something in the factory class itself to return those mock objects if it detects it's running in "test" mode.
I run into this frequently enough that I thought I'd see what others had to say about it.
Using the StyleCop conventions, I find that I often have a property name that is hard to make different than the class name it is accessing. For example:
public class ProjectManager
{
// Stuff here
}
public class OtherClass
{
private ProjectManager ProjectManager { get; set; }
}
It compiles and runs, but seems like it would be an easy way to confuse things, even with the use of "this".
hello I want to make a magnifying glass on a picture so that the part of picture is extended ? in other words i want to find a easy method to create the illusion of a magnifying glass,I know ShapeDrawable and BitmapShader(Bitmap, Shader.TileMode.REPEAT,
Shader.TileMode.REPEAT) is useful,but I donot konw how tu du it.

could you give me some code or sample? thank you
