When trying to obtain the call stack of a thread of some process, I always get a single same frame, although it is for sure has more (at least 5 frames).
StackWalk64() always succeeds on the first call - return a frame with:
AddrPC.Offset = 18446744072850558156
But, immediately on the second call it fails with error id 998-ERROR_NOACCESS (it might be that this error is not because of this call, as MSDN says).
Moreover, trying to resolve this address into its symbol name with SymFromAddr() fails with error 126-ERROR_MOD_NOT_FOUND (after successful SymInitialize(m_processHandler,NULL,TRUE) call).
Here is the code:
#ifdef _M_IX86
//
// Disable global optimization and ignore /GS waning caused by
// inline assembly.
//
#pragma optimize( "g", off )
#pragma warning( push )
#pragma warning( disable : 4748 )
#endif
bool EchoProfiler::getThreadStackTrace(__in HANDLE h_thread, __out vector<DWORD64> &framesVec)
{
CONTEXT threadContext;
if (GetThreadContext(h_thread, &threadContext) == 0)
{
cout << "Error: GetThreadContext() failed with error ID " << GetLastError() << endl;
return false;
}
//initialize stack frame
DWORD MachineType;
STACKFRAME64 StackFrame;
ZeroMemory( &StackFrame, sizeof( STACKFRAME64 ) );
MachineType = IMAGE_FILE_MACHINE_I386;
StackFrame.AddrPC.Offset = threadContext.Eip;
StackFrame.AddrPC.Mode = AddrModeFlat;
StackFrame.AddrFrame.Offset = threadContext.Ebp;
StackFrame.AddrFrame.Mode = AddrModeFlat;
StackFrame.AddrStack.Offset = threadContext.Esp;
StackFrame.AddrStack.Mode = AddrModeFlat;
PVOID contextRec = (MachineType == IMAGE_FILE_MACHINE_I386) ? NULL : &threadContext;
int i=0;
// enumerate all the frames in the stack
for (i=1 ; ; i++)
{
if (StackWalk64( MachineType, targetProcessHandler, h_thread, &StackFrame,
contextRec, NULL, SymFunctionTableAccess64, SymGetModuleBase64, NULL ) == false)
{
// in case it failed or we have finished walking the stack.
cout << "Error: StackWalk64() failed with error ID " << GetLastError() << endl;
i--;
break;
// return false;
}
if ( StackFrame.AddrPC.Offset != 0 )
{
// Valid frame.
cout << "Frame #" << i << " address - " << StackFrame.AddrPC.Offset << endl;
framesVec.push_back(StackFrame.AddrPC.Offset);
}
else
{
// Base reached.
break;
}
}
//cout << "StackWalk64 found " << i << " stack frames:" << endl;
//i = 1;
//for (FramesConstItr itr=framesVec.begin() ; itr != framesVec.end() ; itr++ , i++)
// cout << i << " - " << *itr << endl;
return true;
}
#ifdef _M_IX86
#pragma warning( pop )
#pragma optimize( "g", on )
#endif
what could it be?
Solution:
I missed the part said that the context structure must be initialize properly.
Adding the following solved my problem:
memset(&threadContext, 0, sizeof(CONTEXT));
threadContext.ContextFlags = CONTEXT_FULL;
Thanks
For anyone running into this issue in the future, I also suffered from it in our own local codebase when getting stack information from a different process to the current one. The cause was that we were missing PROCESS_VM_READ when getting a handle on the process using OpenProcess().

I have been trying to get printer status from a DNP rx1 printer, but the status of the printer does not change when I open the tray of the printer. Here is an example using py32win library to access the status and it always return status = 0 event when the tray is open.
device_name = win32print.GetDefaultPrinter()
handle = win32print.OpenPrinter(device_name)
# Get the default properties for the printer
properties = win32print.GetPrinter(handle, 2)
When I try win32print.GetPrinter(handle, 6) # 6 = print_info_6 I get the some NotImplementedException. So my guess is that the firmware of the printer have not implemented print_info_6. So I can't get the status from the printer
I have also tried using powershell with:
Get-Printer | Select Name, PrinterStatus
Also no change in status when I open the tray or if there is a paper jam.
Is there anything that I'm overlooking? Is there anything else I can try to get the status of the printer?
PRINTER_INFO_6 works for me in C++ on Windows 10 1903 with OneNote printer.
And when I pause the printer I get status 0x00000001 (PRINTER_STATUS_PAUSED).
The C++ code I used for testing.
#pragma comment(lib, "Winspool")
int main()
{
DWORD bufSize;
WCHAR* buf = NULL;
HANDLE hPrinter = NULL;
PRINTER_INFO_6 info = {};
DWORD needed;
BOOL result = FALSE;
DWORD err;
// Get required buffer size
result = GetDefaultPrinter(NULL, &bufSize);
if(!result)
{
err = GetLastError();
if (ERROR_INSUFFICIENT_BUFFER != err)
{
std::cout << "GetDefaultPrinter failed with error: \n" << GetLastError();
return 0;
}
}
buf = (WCHAR*)calloc(bufSize, sizeof(WCHAR));
result = GetDefaultPrinter(buf, &bufSize);
if (!result)
{
std::cout << "GetDefaultPrinter failed with error: \n" << GetLastError();
return 0;
}
std::wcout << "Printer name: " << buf << "\n";
result = OpenPrinter(buf, &hPrinter, NULL);
if (!result)
{
std::cout << "OpenPrinter failed with error: \n" << GetLastError();
return 0;
}
result = GetPrinter(hPrinter, 6, (LPBYTE)&info, sizeof(PRINTER_INFO_6), &needed);
if (!result)
{
err = GetLastError();
if (ERROR_INSUFFICIENT_BUFFER != err)
{
std::cout << "GetPrinter failed with error: \n" << GetLastError();
return 0;
}
}
BYTE* statBuf = (BYTE*)calloc(needed, sizeof(BYTE));
result = GetPrinter(hPrinter, 6, statBuf, needed, &needed);
if (!result)
{
std::cout << "GetPrinter failed with error: \n" << GetLastError();
return 0;
}
std::cout << "Printer status (low 32bit): " << *((DWORD*)statBuf) << "\n";
statBuf += sizeof(DWORD);
std::cout << "Printer status (high 32bit): " << *((DWORD*)statBuf) << "\n";
getchar();
}
Some issues I found in testing:
Pinter status defined as a DWORD (4 bytes) in PRINTER_INFO_6 structure but GetPrinter requries 8 bytes for it (needed == 8). So you will get ERROR_INSUFFICIENT_BUFFER error when you pass a PRINTER_INFO_6 structure as pPrinter parameter.
There is only PRINTER_INFO_6 defined but no _PRINTER_INFO_6W (Unicode) and _PRINTER_INFO_6A (ANSI) mentioned in the document.
I'm manually mapping a dll into a process which is compiled with (/EHa). This can catch exceptions like the one below. The problem is, since im manually mapping the dll the exceptions/functions are not registered which leads to a crash of the program as soon as a excpetion occurs. To solve this issue i came to the conclusion that i need to use this function "RtlAddFunctionTable(...)". Sadly im unable to get the first two parameters (FunctionTable and EntryCount) to call the function. Can someone help me out and tell me how i can get the first two parameters?
BOOL APIENTRY DllMain(HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved)
{
RUNTIME_FUNCTION runtimeFunction = ?;
DWORD size = ?;
RtlAddFunctionTable(&runtimeFunction, size, (DWORD64)hModule);
try
{
int var = *reinterpret_cast<int*>(0xFFFF);
}
catch (...)
{
cout << "Exception" << endl;
}
return TRUE;
}
Edit, i solved it:
bool EnableExceptions(DWORD64 moduleBase)
{
PIMAGE_DOS_HEADER pDOSHeader;
PIMAGE_NT_HEADERS pNTHeader;
PIMAGE_OPTIONAL_HEADER pOptHeader;
pDOSHeader = (PIMAGE_DOS_HEADER)moduleBase;
if (pDOSHeader->e_magic != IMAGE_DOS_SIGNATURE)
return false;
pNTHeader = (PIMAGE_NT_HEADERS)((PBYTE)pDOSHeader + pDOSHeader->e_lfanew);
if (pNTHeader->Signature != IMAGE_NT_SIGNATURE)
return false;
pOptHeader = (PIMAGE_OPTIONAL_HEADER)& pNTHeader->OptionalHeader;
if (pOptHeader->Magic != IMAGE_NT_OPTIONAL_HDR_MAGIC)
return false;
PRUNTIME_FUNCTION pFunctionTable = (PRUNTIME_FUNCTION)((DWORD64)pOptHeader->DataDirectory[IMAGE_DIRECTORY_ENTRY_EXCEPTION].VirtualAddress + moduleBase);
cout << "functionTable " << hex << functionTable << endl;
DWORD sizeFunctionTable = (pOptHeader->DataDirectory[3].Size / (DWORD)sizeof(RUNTIME_FUNCTION));
cout << "functionTableSize " << dec << functionTableSize << endl;
BOOL success = RtlAddFunctionTable(pFunctionTable, sizeFunctionTable, moduleBase);
cout << "RtlAddFunctionTable " << success << endl;
return success;
}
Since you are building the .DLL with SEH enabled the information you need should already be in the PE file.
According to this blog post, static tables in the PE takes precedence over dynamically added tables.
If you need to use a custom table for some reason then you need to use VirtualAlloc to allocate memory for the table and the code because the addresses are relative (RVA).
I currently try to set up communication between a Windows program and a µC.
I'll show you the code to initialize the port:
int serialCommunication::serialInit(void){
//non overlapped communication
hComm = CreateFile( gszPort.c_str(),
GENERIC_READ | GENERIC_WRITE,
0,
0,
OPEN_EXISTING,
0,
0);
if (hComm == INVALID_HANDLE_VALUE){
cout << "Error opening port." << endl;
return 0;
}
else{
cout << "Opened Port successfully." << endl;
}
if (SetCommMask(hComm, EV_RXCHAR) == FALSE){
cout << "Error setting communications mask." << endl;
return 0;
}
else{
SetCommMask(hComm, EV_RXCHAR);
cout << "Communications mask set successfully." << endl;
}
if (GetCommState(hComm, &dcbSerialParams) == FALSE){
cout << "Error getting CommState." << endl;
return 0;
}
else{
GetCommState(hComm, &dcbSerialParams);
cout << "CommState retrieved successfully" << endl;
}
dcbSerialParams.BaudRate = CBR_115200; // Setting BaudRate = 115200
dcbSerialParams.ByteSize = 8; // Setting ByteSize = 8
dcbSerialParams.StopBits = ONESTOPBIT; // Setting StopBits = 1
dcbSerialParams.Parity = NOPARITY; // Setting Parity = None
if (SetCommState(hComm, &dcbSerialParams) == FALSE){
cout << "Error setting CommState" << endl;
return 0;
}
else{
SetCommState(hComm, &dcbSerialParams);
cout << "CommState set successfully" << endl << endl;
cout << "+---CommState Parameters---+" << endl;
cout << "Baudrate = " << dcbSerialParams.BaudRate << endl;
cout << "ByteSize = " << static_cast<int>(dcbSerialParams.ByteSize) << endl; //static Cast, um int auszugeben und kein char
cout << "StopBits = " << static_cast<int>(dcbSerialParams.StopBits) << endl; //static Cast, um int auszugeben und kein char
cout << "Parity = " << static_cast<int>(dcbSerialParams.Parity) << endl; //static Cast, um int auszugeben und kein char
cout << "+--------------------------+" << endl;
}
/*------------------------------------ Setting Timeouts --------------------------------------------------*/
timeouts.ReadIntervalTimeout = 50;
timeouts.ReadTotalTimeoutConstant = 50;
timeouts.ReadTotalTimeoutMultiplier = 10;
timeouts.WriteTotalTimeoutConstant = 50;
timeouts.WriteTotalTimeoutMultiplier = 10;
if (SetCommTimeouts(hComm, &timeouts) == FALSE){
cout << "Error setting timeouts" << endl;
return 0;
}
else{
SetCommTimeouts(hComm, &timeouts);
cout << "Timeouts set successfully." << endl;
cout << "+--------------------------+" << endl;
return 1;
}
My Read function looks like this:
void serialCommunication::serialRead(void){
bool readStatus;
bool purgeStatus = 0;
bool correctData = 0;
cout << "Waiting for Data..." << endl; // Programm waits and blocks Port (like Polling)
readStatus = WaitCommEvent(hComm, &dwEventMask, 0);
if (readStatus == FALSE){
cout << "Error in setting WaitCommEvent." << endl;
}
else{
cout << "Data received." << endl;
do{
readStatus = ReadFile(hComm, &TempChar, sizeof(TempChar), &NoBytesRead, 0);
SerialBuffer += TempChar; // add tempchar to the string
}while (NoBytesRead > 0);
SerialBuffer.pop_back(); // Delete last sign in buffer, otherwise one "0" too much shows up, for example "23900" instead of "2390"
cout << endl << SerialBuffer << endl;
SerialBuffer = ""; // Reset string
}
So at some point, my µC sends the String "Init complete...!\r\n" after initializing some things. This works well.Init complete proof
Now after that, the communcation produces errors. I am getting Data I should not receive. The µC can only send data, if a specific string is sent to it by the PC. While debugging I could detect, that the µC never receives this specific string and therefore never sends data. In the following picture, I show you what gibberish I am receiving constantly though.
Receiving Gibberish
/EDIT: I am constantly receiving the same gibberish
The funny thing is, I even receive that data, when the µC is completely switched off (Serial Cables are still connected). So there has to be some data at the port, which just is not deleted. I tried to restart the PC aswell, but it didn't help either.
I will also show you my while loop on PC:
while (testAbbruch != 1){
pointer = acMessung(anzahlMessungen, average); // measurement with external multimeter
cout << endl;
cout << "Average: " << average << endl << endl;
if (average >= 30){
testAbbruch = 1; // there won't be a next while iteration
befehl = "stopCalibration\r\n";
serialTest.serialWrite(befehl);
serialTest.serialRead();
}
else{
cout << "Aktion: ";
std::getline (cin, befehl);
befehl = "increment"; //for debugging
if (befehl == "increment"){
befehl.append("\r\n"); // adding it, so the µC can detect the string correctly
serialTest.serialWrite(befehl);
serialTest.serialRead(); // µC has to answer
}
else if(befehl == "decrement"){
befehl.append("\r\n"); // adding it, so the µC can detect the string correctly
serialTest.serialWrite(befehl);
serialTest.serialRead(); // µC has to answer
}
befehl = ""; // string leeren für nächsten Aufruf
}
}
I know my program is far from perfect, but if I understood the serial Communication with Windows correctly, the buffer is deleted while reading.
Is there any clue you could give me?
EDIT// I just wrote a program that expects one of two inputs: One input is called "increment" the other one is called "decrement". Those inputs are sent to the µC via the serial communication port. Every time I try to send "increment" and instantly after that I am reading from the port, I receive the weird data from this picture. Now, every time I try to send "decrement" and instantly after that I am reading from the port, I receive the weird data from that picture.
//
So my guess is that the data somehow is changed and then looped back to the PC? But why and how?!
I have a code that I found on the internet that uses the function GetRawInputDeviceInfo, but it doesn't get the name of the device right. sometimes it doesn't get a name at all. I've searched for an answer and found out that people had this problem on windows XP and windows 7 to. I am using windows 10 so that doesn't really help me.
C++ - WinAPI get list of all connected USB devices (do i need to post the code itself? im new to stack overflow)
At the end of the day what I am trying to do is get the names of all the devices connected to my PC and print them out, but this function doesnt return the name of the mouse either, so if anyone has a suggestion on how to fix it or a better method to get the names Id'e love to hear you'r ideas. thanks in advance, -shon :)

In Windows there are two flavors of API calls: Unicode and ANSI. The former takes and returns UTF-16 encoded Unicode strings; the latter takes and returns 8-bit encoded strings (the exact encoding depends on the OS localization).
You choose which flavor you want to use by #defining (or not #defining) the macro UNICODE. Depending on that the function changes name, with an W or A suffix.
#ifdef UNICODE
#define GetRawInputDeviceInfo GetRawInputDeviceInfoW
#else
#define GetRawInputDeviceInfo GetRawInputDeviceInfoA
#endif
All the structures that may contain text data are also duplicated with the W or A suffixes.
Now your problem: you are not defining UNICODE so you are actually calling GetRawInputDeviceInfoA(), the ANSI flavor, that expects a char*, but you are passing a WCHAR*, that is a UNICODE string!
The solution is easy:
char* wcDeviceName = new char[nBufferSize + 1];
It is unfortunate that this function GetRawInputDeviceInfo() has its arguments overloaded, so it is declared as taking a void*, so the compiler cannot catch the error. If you were calling a simpler function, say SetWindowText() then you would have got a compiler error because of incompatible pointer type.
If you really want the full UNICODE name of the device, you may prefer keep the WCHAR string and then call the UNICODE function specifically:
WCHAR* wcDeviceName = new WCHAR[nBufferSize + 1];
...
GetRawInputDeviceInfoW(..., RIDI_DEVICENAME, wcDeviceName, ...);
I have these variable defined as global variables outside any function
//testing parameters (init to all nonfail)
int serverRandom = 0; //nonzero == fail > gotofail for first sha1 methode
SSLBuffer sigpar= 0; //nonzero == fail > gotofail for second sha1 methode
string hashOut = "nonfail"; //"fail" == error condition > gotofail for third sha1 methode
These variables are used in this function:
static OSStatus SSLVerifySignedServerKeyExchange(SSLContext *ctx, bool isRsa, SSLBuffer signedParams, uint8_t *signature, uint16_t signatureLen)
{
OSStatus err;
cout << "initval:"<< serverRandom<< signedParams<< hashOut<<endl;
if ((err = SSLHashSHA1::update(&hashCtx, &serverRandom)) != 0)
cout << "firstfail" <<endl;
goto fail;
if ((err = SSLHashSHA1::update(&hashCtx, &signedParams)) != 0)
cout <<"secondfail"<<endl;
goto fail;
//goto fail;
if ((err = SSLHashSHA1::final(&hashCtx, &hashOut)) != 0)
cout << "thirdfail" << endl;
goto fail;
cout << "nonfail" << endl;
fail:
SSLFreeBuffer(&signedHashes);
SSLFreeBuffer(&hashCtx);
return err;
}
Note that the global variables ServerRandom and hashout are accessed directly in that function while the sigpar variable is given to the signedParams arguments of the sslVerify function.
Now, I wrote a unit test to test each failing case seperatly via this function
void unittest(){
//all tests passing
cout << "-------------nonfail-------------" << endl;
result = SSLVerifySignedServerKeyExchange(&ctx,isrsa,sigpar,&sig,siglen);
//first test fail
cout << "-------------firstfail-------------" << endl;
serverRandom = 1;
result = SSLVerifySignedServerKeyExchange(&ctx,isrsa,sigpar,&sig,siglen);
serverRandom = 0;
//second test fail
cout << "-------------secondfail-------------" << endl;
sigpar= 1;
result = SSLVerifySignedServerKeyExchange(&ctx,isrsa,sigpar,&sig,siglen);
sigpar= 0;
//third test fail
cout << "-------------thirdfail-------------" << endl;
hashOut = "fail";
result = SSLVerifySignedServerKeyExchange(&ctx,isrsa,sigpar,&sig,siglen);
hashOut = "nonfail";
}
Now it works perfectly for the first fail case eg. outputting the firstfail line. After that It does not work anymore as it just outputs the ---------secondfail-------- & ------thirdfail------- without outputting the failchecks (secondfail/thirdfail).
note that the initval inside sslverify...() shows the correct values, however the update/final function after the first testcause show 0 as a value for the respective values they recieve.
well, it was easy to solve in the end:
in the SSLVerifySignedServerKeyExchange() I just forgot to add {} around the multi-line if's after I added the cout<< so it would always goto fail after the first if
