Double.MaxValue crashes mixed Native/C# application -


we have problem application crashing when calls method uses double.maxvalue. true running in debugger in release version, , happens under 32-bit xp under 64-bit win 7.

if in debugger have breakpoint on line calling method using double.maxvalue, attempt execute method (f11, f10, f5) stop application friendly windows message has caused problem , needs terminated.

replacing double.maxvalue 9999999999 - ok our application - makes problem go away. looking @ il, literally changes constant.

the c# classes being called native code via little c++ mixed mode bridge has native , managed part. our first idea native part might have destroyed managed memory areas - after replacing maxvalue 9999999999 application runs fine, , happily jumps , forth between native , managed part.

we don't deliver trial & error software customer, , love hear ideas going on??

--edit--

here cut-down version of bridge still crashes:

#include <stdio.h> #include <tchar.h> #include <vcclr.h>  // ------------------------------------------------------------- //  managed // -------------------------------------------------------------  #pragma managed  using namespace system; using namespace ourcompany::tools;  // action move text window __int32 aktiontextfenstermove (__int32 i32hncteil, __int32 i32ansicht, void* pvoid) {    return guemanagedwrapper::textfensterverschieben (i32hncteil, i32ansicht, nullptr); }  // ------------------------------------------------------------- //  native // -------------------------------------------------------------  #pragma unmanaged  #define dllexport __declspec(dllexport)  extern "c"  { // action move text window dllexport __int32 guenmbridgetextfenstermove (__int32 i32hncteil, __int32 i32ansicht,         void* pvoid) {   return aktiontextfenstermove (i32hncteil, i32ansicht, pvoid);

} }

---edit 2---

...and here c# code:

public static class guemanagedwrapper {   public static int32 textfensterverschieben (int32 i32hncteil, int32 i32ansicht, fizzbuzz fzzbzz)   {      fzzbzz= new fizzbuzz();      fzzbzz.fd  = double.maxvalue;      return 0;   } }  public class fizzbuzz {     public double fd; }

this crashes; replacing double.maxvalue 9999999999 fixes crash.

i had same problem. visual express 2010 c#

double afunction() {    console.writeline("afunction called");    if (condition) { return somedoublevalue; }    ....    if (condition) { return double.maxvalue; }    return 0; }

crashed stackoverflow, whenever afunction() called (before console message). replacing double.maxvalue double literal solved problem

i have detailsview control on page used edit various fields of record, works in respect. i looking way add 1 column (and if works, why not more) right, absolutely read-only, show same fields of record comparison purposes. i aware there no obvious way such thing out of box detailsview . have looked other controls (transposed gridview , recommended formview , listview ), nothing satisfies. have special data binding setup using detailsview , can't out of without losing features. anyone on how "hack in" additional columns (for display only) on detailsview ? the solution have now, use second detailsview , visible set false in aspx. in code, make sure databind hidden detailsview hosts data third column first, initial detailsview named itemdetails . and in item created event, pass third column html rendering of hidden controls (in last code block) : protected void itemdetails_itemcreated(object sender, eventargs e) { if (dataite...
