Try this: DWORD WINAPI ThreadProc1( LPVOID lpParameter) { … return 0 ; } DWORD WINAPI ThreadProc2( LPVOID lpParameter) { … return 0 ; } … typedef DWORD (WINAPI * THREADPROCFN)(LPVOID lpParameter); THREADPROCFN fntable[4] = {ThreadProc1, ThreadProc2, …} ; //Start the threads for (int i = 0; i < max_number; i++) { DWORD ThreadId ; CreateThread( … Read more
Introduction This question is about a C++ code that is unable to display a bitmap. The code is from a textbook and is not working as expected. In this introduction, we will discuss the possible reasons why the code is not displaying the bitmap correctly. We will also discuss some possible solutions to the problem. … Read more
Running your code, put aside the code logic first, just to show the BMP image, you did not add the correct image path. You can try to add the absolute path of the picture. Like this: DrawBitmap(“C:\\Users\\strives\\source\\C.bmp”,x,y); //This is my picture path. Please enter your picture path correctly. Updated: I retested the code with MinGW, … Read more
I found a solution to my problem. First let me explain how I achieved this: I made 2 watchdog threads that the first one recreates the 5 threads and WatchDogThread2 when terminated and the second one does the same to watchdog 1 (this took me to long because of Thread.IsAlive was always returning true even … Read more
If only kernel32.dll is being changed you could call ntdll.dll!NtReadVirtualMemory (ReadProcessMemory itself calls this function). If ntdll.dll is also seems to be changed by 3rd party process you could copy ntdll.dll to another temporary file (ntdll_copy.dll), and use it: [DllImport(“ntdll_copy.dll”, EntryPoint = “NtReadVirtualMemory”)] private static extern bool NtReadVirtualMemory(IntPtr hProcess, UIntPtr lpBaseAddress, [Out] byte[] lpBuffer, UIntPtr … Read more
Using the TerminateThread function. The function you posted does: PostThreadMessage(hookThreadId, WM_QUIT, (WPARAM) NULL, (LPARAM) NULL); WaitForSingleObject(hookThreadHandle, 5000); So it sends a quit message to that thread, and then waits for it to close. 6 solved stopping a thread in windows [closed]
Is it possible to start a child process inside same address space? I would like to access any exported function localy. No, it’s not possible. The operating system creates a new address space for each process, that is protected to be accessed from other processes. Use threads instead. 9 solved Start child process process inside … Read more
Use SetWindowsHookEx() or SetWinEventHook() with a thread-local hook to capture the MessageBox() dialog’s HWND, then you can use EnableWindow() to disable the button. Here is how to do it using SetWindowsHookEx(): HHOOK hHook = NULL; LRESULT CALLBACK CBTProc(int nCode, WPARAM wParam, LPARAM lParam) { if( nCode == HCBT_ACTIVATE ) { HWND hDlg = (HWND) wParam; … Read more
If this is about the process remaining around in “server mode” after automation, you can just call the quit method on the application object. I edited by answer at How can I run a macro in an Excel file I open with Perl? to include that. (You know, I thought if I told you that … Read more
You’re looking at a callback (a generic programming concept, not specific to Win32), which is usually a reference to a function that you have to write yourself. In order to have the C/C++ compiler check that you’ve defined your callback function correctly, and to simplify usage of such callbacks, a typedef is often used. The … Read more
To turn your C++ code to Visual C++(Windows environment) all you need to do is to change all of your std:char s and std:string s to std:wchar s and std::wstring s, because windows uses wide (‘w’) format for text in Unicode, i.e there can be more then 1 byte per char. In everything else your … Read more
Windows uses the Application User Model ID to group taskbar buttons and jump lists. This lets you group multiple processes together, or in your case split multiple windows from the same process. You can assign a different AppUserModelID to a window by using the SHGetPropertyStoreForWindow() function to obtain the window’s IPropertyStore interface and then set … Read more
Are you sure you have the correct handle value? Assuming your thread is on the same desktop as the other window it is guaranteed to work correctly. If it returns false then the HWND is not valid because A) your HWND variable contains a numerical value that is not a valid HWND, or B) timing … Read more
Choosing the appropriate runtime environment from your project settings: Configuration Propertes -> C/C++ -> Code Generation -> Runtime Library will determine if you rely on statically linking your project to the runtime or dynamically linking via DLLs. If you choose to dynamically link to the runtime then those DLLs need to be present on the … Read more
There are several issues with your code (using legacy APIs, using bad parameters, missing logic, etc). Try something more like this instead: #include <iostream> #include <Windows.h> const DWORD transparenton = 0x00000001; const DWORD transparentoff = 0x00000000; using namespace std; void pause(); void act(HKEY key); bool getTransparency(HKEY key, DWORD &value); void setTransparency(HKEY key, DWORD value); int … Read more
