Setup:
Oracle Virtual Box 6.1
Windows 7 Home Premium x86 and x64
I have the following code running from a Virtual Machine in both versions of win7 32 and 64 bit:
#include <iostream>
#include <Windows.h>
#include <WinInet.h>
#include <thread>
#pragma comment(lib, "wininet.lib")
using namespace std;
bool isURL_Redirected(wstring url)
{
HINTERNET hInternet = InternetOpen(NULL, INTERNET_OPEN_TYPE_DIRECT, NULL, NULL, 0);
if (hInternet)
{
hInternet = InternetOpenUrl(hInternet, url.c_str(), 0, 0, INTERNET_FLAG_NO_AUTO_REDIRECT, 0);
WCHAR lpvData[1000];
DWORD size = sizeof(lpvData);
if (hInternet)
{

cout << "It does redirect." << endl;
else
cout << "It does not redirect." << endl;

}
Outputs:

Why it does not work from a Virtual Machine? It works fine in a real machine though. I noticed that if I change the URL to https://www.google.com it works fine, so I truly believe there's something to do with the URL and the Virtual Machine. Is there a workaround for this?
EDIT
12157 is an internal WinInet error, usually when it can't load its SSL/TLS library. It has nothing to do with sending keys to the HTTPS server.

I am trying to get the money adress to change to whatever i want , but when i try doing so i get 998 error which is ERROR_NOACCESS . I have visual studio ran as administrator.
#include <windows.h>
using namespace std;
int main()
{
HWND hWnd = FindWindowA(NULL, "PC Building Simulator");
if (hWnd == NULL)
{
cout << "App not found" << endl;
Sleep(3000);
exit(-1);
}
else
{
DWORD proccess_ID;
GetWindowThreadProcessId(hWnd, &proccess_ID);
HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, proccess_ID);
if (hProcess==NULL)
{
cout << "App not found" << endl;
Sleep(3000);

int newdata = 500;
DWORD newdatasize = sizeof(newdata);
WriteProcessMemory(hProcess, (LPVOID)0x1B13B498FB0, &newdata, newdatasize, 0);
cout << GetLastError() << endl;
}
}
return 0;
}
The problem for me had an easy fix ,but not that easy to find it . I had to go to configuration manager and changed the platform from Win32 to x64 and that made it work
I'm trying to entirely disable the keyboard using the windows SetupAPI.
At present I can remove the keyboard successfully with no issues using the DIF_REMOVE function like so:
#include <windows.h>
#include <SetupAPI.h>
#include <iostream>
#include <string>
const std::string keyboard_device_instance_path("<my_path_here>"); // Win7
HDEVINFO DeviceInfoSet = ::SetupDiGetClassDevs(nullptr, nullptr, nullptr, DIGCF_ALLCLASSES | DIGCF_ALLCLASSES);
SP_DEVINFO_DATA DeviceInfoData;
::ZeroMemory(&DeviceInfoData, sizeof(SP_DEVINFO_DATA));
DeviceInfoData.cbSize = sizeof(SP_DEVINFO_DATA);
DWORD DeviceIndex = 0;
std::vector<char> DeviceInstanceId(128, '\0');
DWORD RequiredSize = 0;
// Query all devices
while (::SetupDiEnumDeviceInfo(DeviceInfoSet, DeviceIndex++, &DeviceInfoData))
{
// Find the Keyboard
if (::SetupDiGetDeviceInstanceIdA(DeviceInfoSet, &DeviceInfoData, &DeviceInstanceId[0], DWORD(DeviceInstanceId.size()), &RequiredSize))
{
if (keyboard_device_instance_path == &DeviceInstanceId[0])
{
std::cout << "Breaking keyboard\n";
if (!SetupDiCallClassInstaller(DIF_REMOVE, DeviceInfoSet, &DeviceInfoData))
{
std::cerr << "Failed to remove keyboard: " << ::GetLastError() << '.' << std::endl;
}
}
After disabling it, I want to re-enable the keyboard when a condition is met. For this I naturally looked to 'DIF_UNREMOVE' but have had no success.
Here is the code that attempts to re-enable the keyboard:
SP_UNREMOVEDEVICE_PARAMS UnRemoveParams;
UnRemoveParams.ClassInstallHeader.cbSize = sizeof(SP_CLASSINSTALL_HEADER);
UnRemoveParams.ClassInstallHeader.InstallFunction = DIF_UNREMOVE;
UnRemoveParams.Scope = DI_UNREMOVEDEVICE_CONFIGSPECIFIC;
UnRemoveParams.HwProfile = 0;
if (::SetupDiSetClassInstallParams(DeviceInfoSet, &DeviceInfoData, &UnRemoveParams.ClassInstallHeader, sizeof(UnRemoveParams)))
{
std::cout << "Fixing keyboard\n";
if (!SetupDiCallClassInstaller(DIF_UNREMOVE, DeviceInfoSet, &DeviceInfoData))
{
std::cerr << "Failed to re-enable keyboard: " << ::GetLastError() << std::endl;
}
}
This code is used in the while loop immediately after the removal code. I get an error "No such device installed". What is the correct way to do this? I can only use headers supported by windowsXP
I eventually solved this by instead re-enumerating the systems hardware devices like so:
DWORD pdnDevInst = 0;
if (CM_Locate_DevNodeA(PDEVINST(&pdnDevInst), NULL, CM_LOCATE_DEVNODE_NORMAL) != CR_SUCCESS)
{
std::cout << "Failed to revive keyboard\n";
}
else if (CM_Reenumerate_DevNode(pdnDevInst, CM_REENUMERATE_NORMAL) != CR_SUCCESS)
{
std::cout << "Failed to revive keyboard: Renumerate dev node Error\n";
}
I want to upload a file to my FTP server using C++ code and I'm able to FTP my server with FileZilla.
When I run my C++ code, it throws me an output "3" error ( GetLastError() function returned this value to the FtpPutFile() function
#pragma comment (lib,"wininet.lib")
#include <windows.h>
#include <wininet.h> //for uploadFile function
#include <iostream>
using namespace std;
int main()
{
HINTERNET hint, hftp;
hint = InternetOpen("FTP", INTERNET_OPEN_TYPE_PRECONFIG, 0, 0, INTERNET_FLAG_ASYNC);
hftp = InternetConnect(hint, "MY IP ADRESS", INTERNET_DEFAULT_FTP_PORT, "MY NAME", "MY PASS", INTERNET_SERVICE_FTP, 0, 0);
if (!FtpPutFile(hftp, "C://Users//Elliot//Desktop//log.txt", "//log.txt", FTP_TRANSFER_TYPE_BINARY, 0))
{
cout << "FAIL !" << endl;
cout << GetLastError() << endl;
}
else {
cout << "file sended !";
};
InternetCloseHandle(hftp);
InternetCloseHandle(hint);
system("PAUSE");
}
things i have tried :
Changing server ( i made new server but still same result )
Controlling firewall
Running as adminstrator
break points ( the ftpputfile is giving the error )
The error message is clear. File is not there, there is nothing to send. You can easily check the file's path using std::ifstream before continuing with internet functions.
Use FtpSetCurrentDirectory to set a target directory. In this example I used "public_html", maybe your server is different.
#include <windows.h>
#include <wininet.h>
#include <iostream>
#include <string>
#include <fstream>
#pragma comment (lib,"wininet.lib")
using namespace std;
int main()
{
string file = "C:\\path.txt";
string site = "www.site.com";
string user = "username";
string pass = "password";
if (!ifstream(file))
{
cout << "no file\n";
return 0;
}
HINTERNET hint = InternetOpen(0, INTERNET_OPEN_TYPE_PRECONFIG, 0, 0, 0);
HINTERNET hftp = InternetConnect(hint, site.c_str(), INTERNET_DEFAULT_FTP_PORT,
user.c_str(), pass.c_str(), INTERNET_SERVICE_FTP, 0, 0);
if (FtpSetCurrentDirectory(hftp, "public_html"))
{
if (!FtpPutFile(hftp, file.c_str(), "log.txt", FTP_TRANSFER_TYPE_BINARY, 0))
{
cout << "FAIL!" << endl;
cout << GetLastError() << endl;
}
else
{
cout << "file sended !";
}
}
InternetCloseHandle(hftp);
InternetCloseHandle(hint);
return 0;

I am trying to do some dll injection. I think I tried everything I could but cound not solve the problem unfortunately. I always get ERROR CODE 127 which means ERROR_PROC_NOT_FOUND. I am using Windows 7 64 bit.
#include <iostream>
#include <Windows.h>
#include <TlHelp32.h>
using namespace std;
char FileToInject[] = "theDll.dll";
char ProcessName[] = "calc.exe";
typedef HINSTANCE (*fpLoadLibrary)(char*);
bool InjectDLL(DWORD processId);
int main() {
DWORD processId = NULL;
PROCESSENTRY32 pre32 = {sizeof(PROCESSENTRY32)};
HANDLE hProcSnap;
cout << "BEFORECreateToolhelo32Snapshot:" << GetLastError() <<endl;
while(!processId) {
system("CLS");
cout << "Searching..." << endl;
hProcSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
cout << "CreateToolhelo32Snapshot:" << GetLastError() <<endl;
if(Process32First(hProcSnap, &pre32)) {
do {
if(!(strcmp(pre32.szExeFile, ProcessName))) {
processId = pre32.th32ProcessID;
break;
}
}
while(Process32Next(hProcSnap, &pre32));
}
Sleep(1000);
}
cout << GetLastError() <<endl;
while(!InjectDLL(processId)) {
cout << "DLL Injection failed" << endl;
Sleep(1000);
}
cout << "DLL Injected successfully" << endl;
getchar();
CloseHandle(hProcSnap);
return 0;
}
bool InjectDLL(DWORD processId) {
HANDLE hProc;
LPVOID paramAddr;
cout << "START:" << GetLastError() <<endl;
HINSTANCE hDll = LoadLibrary("KERNEL32");
cout << "LoadLibrary:" << GetLastError() <<endl;
fpLoadLibrary LoadLibraryAddr = (fpLoadLibrary)GetProcAddress(hDll, "LibraryLoadA");
cout << "LoadLibraryArr:" << GetLastError() <<endl;
hProc = OpenProcess(PROCESS_ALL_ACCESS, false, processId);
cout << "OpenProcess:" << GetLastError() <<endl;
char DllPath[250] = "C:\\Hacks\test.dll";
paramAddr = VirtualAllocEx(hProc, 0, strlen(DllPath) + 1, MEM_COMMIT, PAGE_READWRITE);
cout << "VirtualAlloxEx:" <<GetLastError() <<endl;
bool MemoryWritten = WriteProcessMemory(hProc, paramAddr, DllPath, strlen(DllPath) + 1, NULL);
cout << "WriteProcessMemory:" << GetLastError() <<endl;
CreateRemoteThread(hProc, 0, 0, (LPTHREAD_START_ROUTINE)LoadLibraryAddr, paramAddr, 0, 0);
cout << "CreateRemoteThread:" <<GetLastError() <<endl;

}
The output is the following:

The program finds the calc.exe as a process with no problem, but after that something goes wrong. Could someone please help me with this?
Thank you,

This is one problem:
char DllPath[250] = "C:\\Hacks\test.dll";
The last backslash is not escaped. Change to:
char DllPath[250] = "C:\\Hacks\\test.dll";
The function is called LoadLibraryA(), not LibraryLoadA():
fpLoadLibrary LoadLibraryAddr =
(fpLoadLibrary)GetProcAddress(hDll, "LibraryLoadA");
A few other suggestions:
Only check GetLastError() if the previous WINAPI function failed.
Only continue processing if the previous WINAPI code (or other code) succeeded.
In
fpLoadLibrary LoadLibraryAddr = (fpLoadLibrary)GetProcAddress(hDll, "LibraryLoadA");
you should rather resolve the string LoadLibraryA. The
OpenProcess:127 ERROR_PROC_NOT_FOUND
VirtualAlloxEx:127 ERROR_PROC_NOT_FOUND (<-- sic)
WriteProcessMemory:127 ERROR_PROC_NOT_FOUND
errors are caused because you're using GetLastError even though these functions maybe didn't even fail. So before calling GetLastError, make sure that these functions yield an error return value (NULL or the like).
I've been trying to write an application, using Qt and mingw32, to download images and set them as the background Wallpaper. I have read several articles online about how to do this, in VB and C#, and to some extent how to do it in c++. I am currently calling the SystemParametersInfo with what seems to be all the correct arguments (no compiler errors) and it fails. No great crash of cymbals, just a 0 returned. GetLastError() returns an equally enlightening 0.
Below is the code I am using (In a slightly modified form, so you do not have to view the object internals).
#include <windows.h>
#include <iostream>
#include <QString>
void setWall()
{
QString filepath = "C:\\Documents and Settings\\Owner\\My Documents\\Wallpapers\\wallpaper.png";
char path[150];
strcpy(path, currentFilePath.toStdString().c_str());
char *pathp;
pathp = path;
cout << path;
int result;
result = SystemParametersInfo(SPI_SETDESKWALLPAPER, 0, pathp, SPIF_UPDATEINIFILE);
if (result)
{
cout << "Wallpaper set";
}
else
{
cout << "Wallpaper not set";
cout << "SPI returned" << result;
}
}
It could be that SystemParametersInfo is expecting an LPWSTR (a pointer to wchar_t).
Try this:
LPWSTR test = L"C:\\Documents and Settings\\Owner\\My Documents\\Wallpapers\\wallpaper.png";
result = SystemParametersInfo(SPI_SETDESKWALLPAPER, 0, test, SPIF_UPDATEINIFILE);
If this works (try it with a few different files just to make sure), you'll need to convert your char * to a LPWSTR. I'm not sure if Qt offers these services, but one function that may help is MultiByteToWideChar.
"C:\Documents and Settings\Owner\My Documents\Wallpapers\wallpaper.png";
shouldn't this be:
"C:\\Documents and Settings\\Owner\\My Documents\\Wallpapers\\wallpaper.png";
You cn use SetTimer to trigger a change.
#define STRICT 1
#include <windows.h>
#include <iostream.h>
VOID CALLBACK TimerProc(HWND hWnd, UINT nMsg, UINT nIDEvent, DWORD dwTime)
{
LPWSTR wallpaper_file = L"C:\\Wallpapers\\wallpaper.png";
int return_value = SystemParametersInfo(SPI_SETDESKWALLPAPER, 0, wallpaper_file, SPIF_UPDATEINIFILE);
cout << "Programmatically change the desktop wallpaper periodically: " << dwTime << '\n';
cout.flush();
}
int main(int argc, char *argv[], char *envp[])
{
int Counter=0;
MSG Msg;
UINT TimerId = SetTimer(NULL, 0, 2000, &TimerProc); //2000 milliseconds
cout << "TimerId: " << TimerId << '\n';
if (!TimerId)
return 16;
while (GetMessage(&Msg, NULL, 0, 0))
{
++Counter;
if (Msg.message == WM_TIMER)
cout << "Counter: " << Counter << "; timer message\n";
else
cout << "Counter: " << Counter << "; message: " << Msg.message << '\n';
DispatchMessage(&Msg);
}
KillTimer(NULL, TimerId);
return 0;
}
