I got this "warning C4290: C++ exception specification ignored except to indicate a function is not __declspec(nothrow)" for several lines in the code

Question

How to fix this warning? The code cannot continue compile because of this warning. Please please give me some suggestions! Thank you so much! I copied four parts of the code where the warning points to.

 template <typename T>
std::vector<StructNodeElem<T> *> *_groupStructOfString(const char *data) throw(const char *){
  std::istringstream is(data);
  std::vector<StructNodeElem<T> *> *gstruct = new std::vector<StructNodeElem<T> *>;


template <typename T>
std::vector<StructNodeElem<T> *> *_readGroupStruct(const char *file) throw(const char *){
  std::ifstream infile;
  infile.open (file, ifstream::in);
  if(! infile.good())
    throw("readGroupStruct: cannot open file");


template <typename T>
std::vector<StructNodeElem<T> *> *_simpleGroupTree(int *degr, int n) throw(const char *){
  std::vector<int> degrees;
  for(int i = 0;i < n;i++)
    degrees.push_back(degr[i]);




template <typename T>
Vector<T> *_graphOfGroupStruct(std::vector<StructNodeElem<T> *> *gstruct,SpMatrix<bool> **pgroups,SpMatrix<bool> **pgroups_var) throw(const char *) {
  int nb_vars;
  Vector<T> *peta_g;
  if (! checkGroupTree<T>(gstruct,false,&nb_vars))
    throw("graphOfGroupStruct: bad input data");




template <typename T>
int _treeOfGroupStruct(std::vector<StructNodeElem<T> *> *gstruct,int **pperm,int *pnb_vars,Vector<T> **peta_g,SpMatrix<bool> **pgroups,Vector<int> **pown_variables,Vector<int> **pN_own_variables) throw(const char *){
  int nb_vars;
  *pnb_vars = 0;
  if (! checkGroupTree<T>(gstruct,true,&nb_vars))
    throw("treeOfGroupStruct: bad input data");

Check the msdn http://msdn.microsoft.com/en-us/library/sa28fef8.aspx.

Summary, just use the pragma #pragma warning( disable : 4290 )
