Attempts to resolve problem in java: Apache Batik does not support EMF+ format (Batik supports WMF only format). FreeHEP does not support EMF+ too. It can convert EMF to SVG and then SVG to PNG . I hoped it can help: EMF2SVG.main( new String[] {inputMetaFileName,ontputSvgFileName}); this statement must convert EMF to SVG , but gives an exception: java.lang.NullPointerException at org.freehep.graphicsio

I have to set each character in a string to an integer so that I can sum their values. Please help! It it something like this?? int hashCode(string s) { int Sum = 0; for(int i=0; i<strlen(s); i++) { Sum += (int)s[i]; } return Sum; } 回答1: Yes -- in C and C++, char is just a small integer type (typically with a range from -128 to +127). When you do math on it, it'll normally be converted to int automatically, so

For example: number.ToString("E") 回答2: Use this. string.Format("{0:#.0#E-00}", NumericValue); or string.Format("{0:E}", NumericValue); 文章来源: How to convert non

What it the real layout of eigen matrix? Is the real data stored as in normal c array? 回答1: You can use the data() member function of the Eigen Matrix class. The layout by default is column-major, not row-major as a multidimensional C

I'm using jQuery to manage the sort order of the columns, but each column is ordered like an Excel spreadsheet i.e. a b c d e......x y z aa ab ac ad etc etc How can I generate a number as a letter? Should I define a fixed array of values? Or is there a dynamic way to generate this? 回答1: I think you're looking for something like this function colName ( n ) { var ordA = 'a' . charCodeAt ( 0 ); var ordZ = 'z' . charCodeAt ( 0 ); var len = ordZ - ordA +
