  • Set A Transparent Color

    - by Ngu Soon Hui
    I have a Color, and I have a method that should return a more "transparent" version of that color. I tried the following method: public static Color SetTransparency(int A, Color color) { return Color.FromArgb(A, Color.R, Color.G, Color.B); } but for some reason, no matter what the A is, the returned Color's transparency level just won't change. Any idea?

  • Java converting to Jython-Getting a class object within itself

    - by Bggreen
    I am attempting to convert Java code to Jython and am using the apache Log and LogFactory imports. I am attempting to emulate Foo.class in Jython The chunk of code is as follows: in Java import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; public class MyClass { private static final Log log = LogFactory.getLog(MyClass.class); public MyClass(Document dom) { //code } How can I emulate this same behavior of MyClass.class in Jython/Python?

  • Lifetime of a const string literal returned by a function

    - by Neeraj
    Consider this code: const char* someFun() { // ... some stuff return "Some text!!" } int main() { { // Block: A const char* retStr = someFun(); // use retStr } } My question is in the function sumFun() where is "some Text!!", stored (i think may be in some static area in ROM) and what will be its scope? Will the memory pointed by retStr be occupied throughout the program or be released once the block A exits? -- Thanks

  • controlling the class names generated by JAXB for xsd:attributeGroup?

    - by Stephen Winnall
    I am using JAXB to bind XML to Java for an application that I am writing. I have an element called measure which contains two amount elements called amount and maxAmount, with which I want to model a lower and an upper limiting value. amount and maxAmount are otherwise identical and I would like them to be implemented with the same class when unmarshalled into Java. The following is an extract from the XML schema which I feed to JAXB: <xsd:attributeGroup name="AmountAttributes"> <xsd:attribute name="quantity" type="xsd:decimal"/> <xsd:attribute name="numerator" type="xsd:nonNegativeInteger"/> <xsd:attribute name="denominator" type="xsd:positiveInteger"/> </xsd:attributeGroup> <xsd:element name="measure"> <xsd:complexType> <xsd:sequence> <xsd:element minOccurs="0" name="amount"> <xsd:complexType> <xsd:attributeGroup ref="mpr:AmountAttributes"/> </xsd:complexType> </xsd:element> <xsd:element minOccurs="0" name="maxAmount"> <xsd:complexType> <xsd:attributeGroup ref="mpr:AmountAttributes"/> </xsd:complexType> </xsd:element> </xsd:sequence> </xsd:complexType> </xsd:element> JAXB creates from this a more elaborate version of the following: public class Measure { protected Measure.Amount amount; protected Measure.MaxAmount maxAmount; public static class Measure.Amount {} public static class Measure.MaxAmount {} } Measure.Amount and Measure.MaxAmount are identical except for their names, but - of course - as far as Java is concerned they have little to do with each other. Is there a way of making JAXB use the same class for both amount and maxAmount? Just to come completely clean ;-) I should mention that I generate the XML schema from RNC using Trang. If the answer to the question is "change the XML schema", I have the supplementary question "how do I change the RNC to produce that XML schema?". My RNC looks like this: AmountAttributes = QuantityAttribute? & attribute numerator { xsd:nonNegativeInteger }? & attribute denominator { xsd:positiveInteger }? QuantityAttribute = attribute quantity { xsd:decimal } Measure = element measure { element amount { AmountAttributes }?, element maxAmount { AmountAttributes }? }+ I use RNC because I find it simpler to understand, but if the solution to my problem means just using XML Schema, so be it.

  • Multitenant NHibernate application with with separate SQL Server schema for each tenant

    - by Branko
    I am writing a new multi-tenant WCF RIA application. I plan to have a shared database with separate SQL Server schema for each tenant. I would like to use NHibernate for object-ralational mapping. Configuration of SQL Server schema in mapping classes doesn't help because it is static and would need one set of mapping classes for each tenant. Is it possible to dynamically configure ISession which SQL Server schema should be used for mapping objects to tables?

  • Weird behaviour of Calendar and DateFormat

    - by Nejc
    I encountered really strange behaviour when constructing a Calendar object and then formating it in a particular style. Let the code do the talking: public class Test { public static void main(String[] args) { SimpleDateFormat frmt = new SimpleDateFormat(); frmt.applyPattern("yyyy-MM-dd"); GregorianCalendar date = new GregorianCalendar(2012,1,1); System.out.println(frmt.format(date.getTime())); } } The output is: 2012-02-01 The expected output is of course: 2012-01-01 What am I doing wrong?
