Thank you for the fast reply, but is there another way to solve this problem, cause it's to much to change in the program code (there are a lot of files to changed!). Yes, there is another way. Compile your application in ansi and NOT in uncicode mode using the wx-config --unicode=no. This requires...

Hi, you are compiling in unicode mode. This requires wxT() macros when using char*. #include "GUI.h" #include "Case.h" #include "Color_Key.h" #include "wx/bitmap.h" IMPLEMENT_APP(GUI) wxApp * theApp = &wxGetApp(); bool GUI::OnInit() { add_case(); return true; } Case * GUI::add_case() { int x, y; Cas...

Hm, I don't know where your error lies, because I do not see the full code, but quick solution for this would be: double d1 = ay[p][0]; double d2 = ay[p][1]; GetCellValue(p,0).ToDouble(&d1); GetCellValue(p,1).ToDouble(&d2); hey thanks for your help. I think the wxString GetCellValue(int r, int c) i...

have you tried to following:

Code: Select all

wxGrid *pGrid = new Grid(...)
int row,col;
/// ...
pGrid-> SetCellValue(row,col,wxString::Format(wxT("%f"),myFloatValue));

Well, I could find this: http://www.delphi3000.com/articles/article_3772.asp?SK= , it does 128-bit arithmetic using 32-bit registers but it's written in Pascal. I think it's pretty easy to convert the functions to C plus inline assembly. Cheers, Andre That link is very helpful. I can understand the...
