I am using the Win32 API to create an application to assist in making a custom .font file format for a game I am making. It is a SDI application. Although my question may seem simple, I was unable to find anyway of doing it, or maybe searching for the wrong thing, I don't know. Anyway, I want to be able to programatically change the size of the window, at run time. I have a title bar, menu, and borders, and I don't want to have them included when resizing. By that I mean, for example, I wanted to resize the window to 500 pixels by 500 pixels, the white space in between (not including) the menu and borders would be 500 pixels by 500 pixels. Also, I want to disable the user from resizing the application. Anyone have any ideas? Thank you -Dev578

I'm not so sure why, but when I commented out the MessageBox in the main program, it did not crash. It installed and removed the hook successfully (to my knowledge). I have another problem though. With the hook installed, if I try to open another program, like Internet Explorer or some kind of software, Windows Crashes. It freezes and then all my icons dissappear and the taskbar goes away, leaving only the background and the cursor. Anyone have any idea why this would be happening? Any help is appreciated. Thanks in advance -Dev578

I am trying to inject a dll into all running processes so I can hook all calls to CreateProcess(). I am going to intercept all calls to CreateProcess() by modifying the IAT, I know how to do that. My problem is injecting the dll into all processes using SetWindowsHookEx(). This is my code, it runs once or twice (triggering the MessageBox function in the main program), and then if you run it again, the computer freezes (and doesn't trigger the MessageBox function in the main program, meaning it got stuck on the InjectEnable() function). If anyone knows what the problem is, that would be highly appreciated. // Main program: #include //windows header #include //stdio header #include "MyDLL.h" #pragma comment(lib,"MyDLL.lib") int WINAPI WinMain(HINSTANCE hInst, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) { InjectEnable(); // Function in MyDLL.dll, enables injection MessageBox(NULL,"End Application","Notification",MB_OK); InjectDisable(); // Function in MyDLL.dll, disables injection return 0; } // DLL cpp file: #define WIN32_LEAN_AND_MEAN // Exclude rarely-used stuff from Windows headers #include // Windows header #include "MyDLL.h" // Global variables (shared) #pragma data_seg (".shared") HHOOK g_hHook = 0; #pragma data_seg () #pragma comment(linker,"/SECTION:.shared,RWS") // Global variables (unshared) HINSTANCE hDll; BOOL APIENTRY DllMain( HANDLE hModule, DWORD ul_reason_for_call, LPVOID lpReserved ) { switch (ul_reason_for_call) { case DLL_PROCESS_ATTACH: { hDll = (HINSTANCE)hModule; break; } case DLL_THREAD_ATTACH: { break; } case DLL_THREAD_DETACH: { break; } case DLL_PROCESS_DETACH: { break; } default: break; } return TRUE; } LRESULT HookProc ( int code, // hook code WPARAM wParam, // virtual-key code LPARAM lParam // keystroke-message information ) { return ::CallNextHookEx(g_hHook, code, wParam, lParam); } bool MYDLL_API InjectEnable() { g_hHook = SetWindowsHookEx( WH_CBT, (HOOKPROC)HookProc, hDll, NULL ); if( g_hHook == NULL ) { return false; } return true; } bool MYDLL_API InjectDisable() { UnhookWindowsHookEx( g_hHook ); g_hHook = NULL; // Send a broadcast message, this forces the hook to trigger, and thus unload SendMessage(HWND_BROADCAST,WM_NULL,0,0); return true; } // DLL header file: #ifdef MYDLL_EXPORTS #define MYDLL_API __d

I have my dll injected into another process. Is there a way from that dll that I can tell what other dll's are mapped into the process, and be able to get the module handle to one of them? Any help is appreciated. -Dev578

Here is the function: HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS,FALSE,WindowProcessID); WindowProcessID is a DWORD. How do I get the Process ID of a window for use in the third parameter of OpenProcess()? Any help is appreciated. -Dev578

I want to get the HWND of a window by FindWindow(). The second parameter is the window name, but the window name I am trying to get has a copyright symbol in it (a c with a circle around it). Is there a way that I can have FindWindow() only search for the first few characters in the window name? or is there a way to put a copyright symbol in a string? Any help is appreciated. -Dev578

I am having trouble with the "Process-wide api spying" article by Anton Bassov. Here is the code: HMODULE hMod = GetModuleHandle("kernel32.dll"); if (hMod == NULL) MessageBox(NULL,"could not load dll","error",MB_OK); else { IMAGE_DOS_HEADER * dosheader=(IMAGE_DOS_HEADER *)hMod; IMAGE_OPTIONAL_HEADER * opthdr =(IMAGE_OPTIONAL_HEADER *) ((BYTE*)hMod+dosheader->e_lfanew+24); IMAGE_IMPORT_DESCRIPTOR * descriptor=(IMAGE_IMPORT_DESCRIPTOR*)(BYTE*)hMod + opthdr->DataDirectory[IMAGE_DIRECTORY_ENTRY_IMPORT].VirtualAddress; while(descriptor->FirstThunk) { char*dllname=(char*)((BYTE*)hMod+ descriptor->Name); IMAGE_THUNK_DATA* thunk=( IMAGE_THUNK_DATA*)((BYTE*) hMod + descriptor->OriginalFirstThunk); int x=0; while(thunk->u1.Function) { char*functionname=(char*)((BYTE*) hMod + ( DWORD)thunk->u1.AddressOfData+2); MessageBox(NULL,functionname,"function",MB_OK); DWORD *IATentryaddress=( DWORD *)((BYTE*) hMod + descriptor->FirstThunk)+x; x++; thunk++; } descriptor++; } } It is crashing at run-time, saying that it cannot read from desciptor. Anyone have any idea what the problem is? Any help is appreciated. -Dev578

I have a static function inside a class. It is actually a seperate thread, so it has to be static. Is there a way that I can access normal members of the class from the static thread funcion? Any help is appreciated. -Dev578

I am trying to create the thread inside a class: class ThreadClass { public: //... bool StartThread(); DWORD WINAPI ThreadFunc( LPVOID lpParam ); //... }; bool ThreadClass::StartThread() { DWORD dwThreadId, dwThrdParam = 1; HANDLE hThread; hThread = CreateThread( NULL, // default security attributes 0, // use default stack size ThreadFunc, // thread function &dwThrdParam, // argument to thread function 0, // use default creation flags &dwThreadId); // returns the thread identifier return true; } DWORD WINAPI ThreadClass::ThreadFunc( LPVOID lpParam ) { //do whatever here return 0; } this produces this error: error C2664: 'CreateThread' : cannot convert parameter 3 from 'DWORD (LPVOID)' to 'LPTHREAD_START_ROUTINE' Any ideas why it is doing this / how to fix it? Any help is appreciated. -Dev578

When I use AfxBeginThread in a Win32 application, I get this error: error C3861: 'AfxBeginThread': identifier not found, even with argument-dependent lookup Not found? When I type AfxBeginThread and then the ( , it lists the parameters for it. Any idea why it is doing this? Any help is appreciated. -Dev578

How would one convert a float to an int without rounding it? Currently: float f = 1.9; int i = (int)f; i would equal 2. How do I get it to not round, and have i equal 1 in the above example? Any help is appreciated. -Dev578

I have made a window in Win32. I would like to somehow handle the minimize event, so I can do stuff when the user clicks the minimize button. Does anyone have any clue how to do this? Any help is appreciated. -Dev578

I am making a Win32 project in VC++ v7. When I click on the executable, I want it to run in the task bar. How would I do this? Any help is appreciated. -Dev578

I have run into some problems while trying to write a scripting language in VC++ 7. I want it to all be in an edit box. For example, if the user types this in the edit box: String MyString = "Hello"; if (MyString == "Hello") sendkeys(Hello); else MoveMouse(160,480); end; Quite a pointless program, but I am having a hard time handling it with C++. How do I handle the boolean logic, and how would I get both of the parameters of the MouseMove function. I would like the program to execute from the top to the bottom. Anyone have any idea how to do this? I just need the basic idea of how to do it. Any help would be appreciated:) -Dev578

I made an empty Win32 project in VC++ v7, and then added a C++ file to it. I made an exact copy of one of the Direct3D working tutorials and pasted it into the empty C++ file. I copied all of the DirectX include files and library's into the directories tbat VC++ uses. When I try to build it, it gives me the following errors: Linking...

Awile ago, I had asked how to read the binary off of a CD. Alexander said that I would have to use an "IOCTL" (Thanks for your reply Alexander). Sorry, I am still quite new to MFC... What exactly is an IOCTL? Alexander said that the IOCTL to use is IOCTL_CDROM_RAW_READ. I think I have it defined in a header file called ntddcdrm.h. IOCTL_CDROM_RAW_READ is not a function, so I am assuming I need to use it in a function or something? If anyone could help me out, that would be great. Any help is apprectiated. -Dev578

To my understanding, a CD has 0's and 1's (binary) written on it, and a laser reads the binary. Then the computer translates it. Please correct me if I am wrong. I am using MFC, and what I am trying to do is get all the binary data off of a CD, and put it to a char. Is this possible? Any help at all is appreciated. -Dev578

As said before, what I am tying to do is get the letters of all the CD/DVD drives on the users computer using MFC. This is what I have so far: DWORD Drives = GetLogicalDrives(); CString FormatString; FormatString.Format("%i",Drives); DriveControl.SetWindowText(FormatString); FormatString returns 61... I have no idea why it is returning 61. I am assuming that I am doing it wrong? If anyone could show me how to do this right, that would be great. -Dev578

I am using MFC, how would I go about finding and displaying all of the CD/DVD drives of the users computer? I have been looking around for articles, and have not found anything yet. Any help is appreciated. -Dev578

I am using MFC with Visual Studio 2003. Is there a way to retrieve all of the written data off of a CD, and save it as a file? I don't know weather or not copy protection is going to be an issue, and I am assuming that this is not going to be an easy thing to do, so any help at all is appreciated:) -Dev578
