comment puis-je lancer par programme une application à partir d'un raccourci Windows (fichier .lnk)?Comment puis-je lancer par programme (C++) une application à partir d'un raccourci Windows (fichier .lnk)?
J'ai essayé d'utiliser l'API ShellExecute et cela semble fonctionner. Toute mise en garde?
Merci.
Ici, il est un extrait de mon code actuel:
#include <windows.h>
#include <map>
#include <string>
#include <iostream>
int main(int, char**)
{
std::map< int, std::wstring > errors;
errors[0] = L"The operating system is out of memory or resources.";
errors[ERROR_FILE_NOT_FOUND] = L"The specified file was not found.";
errors[ERROR_PATH_NOT_FOUND] = L"The specified path was not found.";
errors[ERROR_BAD_FORMAT] = L"The .exe file is invalid (non-Microsoft Win32 .exe or error in .exe image).";
errors[SE_ERR_ACCESSDENIED] = L"The operating system denied access to the specified file.";
errors[SE_ERR_ASSOCINCOMPLETE] = L"The file name association is incomplete or invalid.";
errors[SE_ERR_DDEBUSY] = L"The Dynamic Data Exchange (DDE) transaction could not be completed because other DDE transactions were being processed.";
errors[SE_ERR_DDEFAIL] = L"The DDE transaction failed.";
errors[SE_ERR_DDETIMEOUT] = L"The DDE transaction could not be completed because the request timed out.";
errors[SE_ERR_DLLNOTFOUND] = L"The specified DLL was not found.";
errors[SE_ERR_FNF] = L"The specified file was not found.";
errors[SE_ERR_NOASSOC] = L"There is no application associated with the given file name extension. This error will also be returned if you attempt to print a file that is not printable.";
errors[SE_ERR_OOM] = L"There was not enough memory to complete the operation.";
errors[SE_ERR_PNF] = L"The specified path was not found.";
errors[SE_ERR_SHARE] = L"A sharing violation occurred.";
int ret = reinterpret_cast<int>(::ShellExecute(0,L"open",L"\"C:\\Documents and Settings\\All Users\\Start Menu\\Programs\\Accessories\\Calculator.lnk\"",0,0,SW_SHOW));
const int minimumRetOK = 33;
if (ret < minimumRetOK) {
if (errors.count(ret)) {
std::wcout << L"Error " << ret << L" " << errors[ ret ];
} else {
std::wcout << L"Error " << ret << L" undocumented error";
}
}
return 0;
}
Merci pour votre explication. –
