  • Convert XML to UDT in Oracle

    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.

  • Tooltip steals mouse click

    - by deerchao
    I'm writing a custom TreeView from ScrollableControl. I decided to show tooltips when the mouse hovers over nodes with text too long to display. I find that when tooltips are shown, the user is not able to click the node to select it because (I think) he's clicking the tooltip window, not my control. Is there any easy solutions? As far I can see, System.Windows.Forms.TreeView don't have this problem. Thanks!

  • Comparing floats in their bit representations

    - by sczizzo
    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?

    - by TK
    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.

    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

  • Calculating volume for sphere in c++

    - by Crystal
    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); }

  • which of these modes : cbc,cfb,ctr,ecb,ncfb,nofb,ofb,stream are secure and which are absolute no-no

    - by user393087
    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.

    - by mnn
    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.

  • Identifying voice as male or female

    - by duder
    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.

  • Browser size (width and height)

    - by dono
    I'm trying to detect the browser's current size (width and height). I know it's super easy in jquery with $(document).width and $document.height, but I don't want to add the size of the jquery lib to the project, so I'd rather just use built in javascript. What would be the short and efficient way to do the same thing with javascript?

  • How do I integrate a BSDF into a ray caster.

    - by pelb
    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!
