java - Passing 2D Array argument with JACOB -

-

i have com method i'm trying invoke, there's argument of type 'object' must 2d double safe array, collection of lat/long points. how can create safearray in jacob send through com interface?

i've tried passing 2d array object in object list. method doesn't return error, not see results expect in falconview (rendering of polygon).

    double polypoints[][] = new double[5][2];     polypoints[0][0] = 75.3;     polypoints[0][1] = 4.5;          polypoints[1][0] = 3.8;     polypoints[1][1] = 4.8;     polypoints[2][0] = 2.3;     polypoints[2][1] = 2.5;     polypoints[3][0] = 5.3;     polypoints[3][1] = 6.5;     polypoints[4][0] = 0.3;     polypoints[4][1] = -1.5;  // can't recreate variant or safearray double[x][y] array;      object[] polygonargs = new object[] {m_mainlayerhandle, polypoints, 1};     variant returnaddpolygon = dispatch.invoke(mainlayerdispatch, "addpolygon", dispatch.method, polygonargs,  new int[1]);     system.out.println("polygon handle: " + returnaddpolygon.getint());      object[] refreshargs = new object[] {m_mainlayerhandle};     variant refreshvariant = dispatch.invoke(mainlayerdispatch, "refresh", dispatch.method, refreshargs,  new int[1]);

the second arument documentation:

lat_lon_array 2 dimensional safearray of doubles. first dimension contains latitude values. second dimension contains longitude values

it seems safearray supports 1 dimensional, 2 dimensional, , n-dimensional arrays using unclear constructors. given 2d double array created above, able copy data in 2d double safe array. more efficient create double[][] front, i'm doing in prototype code. there may ways copy entire arrays in safe array... not sure.

// 2d array of type double. first dimension size 5, second dimemnsion size 2. safearray safearray = new safearray(variant.variantdouble, 5, 2); for(int = 0; < 5; i++) {     (int j = 0; j < 2; j++) {             // set value of safearray[i][j] value polypoints[i][j]         safearray.setdouble(i, j, polypoints[i][j]);     } }

i use sonar plugin executes if activated in maven profile. sonar runs on every compile. the problem build fail other team members not have sonar application installed locally. pom.xml checked in team members same copy including sonar configuration, don't want them modify purpose of disabling sonar (they might inadvertently check modified copy in). please advise how configure maven (.m2/settings.xml) and/or pom.xml sonar feature can enabled/disabled local profile. here sonar configuration in each project's pom.xml: <plugin> <groupid>org.codehaus.mojo</groupid> <artifactid>sonar-maven-plugin</artifactid> <version>1.0</version> <executions> <execution> <id>make-sonar</id> <phase>compile</phase> <goals> <goal>sonar</goal> </goals> </execution> </executions> ...

python - TypeError: can only concatenate tuple (not "float") to tuple -

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...

this question has answer here: meaning of .this , .class in java 2 answers i'll straight point. im still learning bit of syntax , want know difference between code is code a: public class buttonz extends jbutton{ public buttonz(){ settext(new string(string.valueof(i))); } } please ignore fact i undeclared, not lost. code b: public class buttonz extends jbutton{ public buttonz(){ settext(new string(string.this.charat(i))); } } what don't yet understand difference in typing string.this , string. i under assumption when use dot operator on class accessing it's static methods(and/or variables if they're not hidden). i have studied little bit , have concluded when using string. accessing string static methods.. when using string.this. i'm accessing methods class buttonz extendi...
