RegSetValueEx inputting incorrect data into Registry
The issue I'm having is that my application is inputting the incorrect data into the registry (instead of a file path, it inputs characters such as "㩃啜敳獲啜敳屲灁") and I don't know what the issue is, the relevant source code is below (Includes, etc have been removed).
stringstream ss; char* file_path = getenv("APPDATA"); strcat(file_path, "\\Application.exe"); ss << file_path; ss >> file_path_string; CA2W unicodeFile_path(file_path); cout << "Downloading File"; HRESULT hr = URLDownloadToFile ( NULL, _T("http://example.com/application.exe"), unicodeFile_path, 0, NULL ); cout << "Done" << endl; cout << "Adding to registry" << endl; HKEY hKey; CA2W registryLocation("Software\\Microsoft\\Windows\\CurrentVersion\\Run"); CA2W registryKey("Application"); // Check registry if exists, otherwise create. RegCreateKeyEx(HKEY_CURRENT_USER, registryLocation, 0, NULL, REG_OPTION_NON_VOLATILE, KEY_WRITE, NULL, &hk, &dwDisp); // Store reg value RegSetValueEx(hk, registryKey, NULL, REG_SZ, (const BYTE*)file_path_string.c_str(), file_path_string.size() + 1);
Any help will be appreciated.
RegSetValueEx expects (for REG_SZ) that the data you're passing in is Unicode, unless you're not defining UNICODE in your environment. But .c_str is likely a non-Unicode stream.
