 | Re: sort array When you exchange one array during the sort you have to make similar exchanges in the second array. That's one reason that many (most?) programmers put suich things in an array of structures -- to make sorting a lot simpler. [code] struct data { int a; int b; }; [/code] … |
| | Impossible to answer that question. There are probably billions of Fortran programs and each one would be a unique port. In many cases porting may not even be possible depending on the mathametical complexities of the fortran program. VB does not have the efficient mathametical functions that are available to … |
| | why don't you format the string and then send it to sybase. The code below won't be 100% correct because it does not account for the floats and integers. The main thing is that you have to surround all strings with quotes, and nothing for floats/integers. You can not pass … |
