Problemas com RegQueryValueEx

Michel. · 23 de abril de 2011

Opa, tenho o seguinte código

void PROGRAMDlg::WxButton1Click(wxCommandEvent& event)
{
    HKEY hk;
    DWORD dwType;
    DWORD dwLength;
    [B]char value[MAX_PATH] = { 0 };[/B]
    RegOpenKeyEx(HKEY_LOCAL_MACHINE,
		           "SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion",
				   0,
				   KEY_QUERY_VALUE,
				   &hk);
    RegQueryValueEx(hk,
		             "ProductName",
		             NULL,
		             NULL,
		             (LPBYTE)&value,
		             &dwLength);
	WxStaticText4->SetLabel( [B]value[/B] );
	    RegQueryValueEx(hk,
		             "CurrentBuild",
		             NULL,
		             NULL,
		             (LPBYTE)&value,
		             &dwLength);
	WxStaticText8->SetLabel( [B]value[/B] );
		    RegQueryValueEx(hk,
		             "ProductId",
		             NULL,
		             NULL,
		             (LPBYTE)&value,
		             &dwLength);
	WxStaticText6->SetLabel( [B]value[/B] );

}
