loadlibrary

I need to open a html help file from within a legacy windows application written in old version of C++ Builder. HtmlHelp is loaded via HtmlHelp.ocx, which I am loading via LoadLibrary. This has worked fine for years, but it does not work anymore in Windows 7 x64. It might also fail under Windows7 x86, but I don't have any computer with this OS, so I can't try it out at the moment. I am loading hhctrl.ocx dynamically as follows: #define HHPathRegKey "CLSID\\{adb880a6-d8ff-11cf-9377-00aa003b7a11}\\InprocServer32" bool THTMLHelper::LoadHtmlHelp() { HKEY HHKey; DWORD PathSize = 255; char Path[255]

I am using windows 7 64 bit machine. I installed Visual studio 2010 and developed a simple win32 dll to add 2 numbers.. The dll is created and i used a test application to test the dll and it works fine.. Now i write python script(shown below) to use this library. But i get the following error message. Traceback (most recent call last): File "C:\Users\sbritto\Documents\Visual Studio 2008\Projects\MathFuncsDll\Debug\MathFuncs.py", line 5, in <module> lib = ctypes.WinDLL('MathFuncsDll.dll',use_last_error=True) File "C:\Python27\lib\ctypes\__init__.py", line 365, in __init__ self._handle =

My code uses LoadLibraryA("someDLL.dll"); What is the path it starts searching for the file someDLL.dll?And another question : is LoadLibraryA function case-sensitive?I mean if I have SomeDLL.dll it will not load it? The MSDN Library article Dynamic-Link Library Search Order specifies the search order for desktop applications when SafeDllSearchMode is enabled, which is the default starting with Windows XP SP2: The directory from which the application loaded. The system directory. Use the GetSystemDirectory function to get the path of this directory. The 16-bit system directory. There is no

I'm stuck as to why I can't load my dll "interfac" using LoadLibrary. It seems to be failing when loading a dependency but I'm not sure why. Here's the code: AfxMessageBox(L"before load library"); HMODULE interfacDll = LoadLibrary(TEXT("C:\\QA\\Pcdlrn\\Win32\\Release\\INTERFAC.DLL")); if (!interfacDll) DWORD dw = GetLastError(); // returns 0xc1 (193) AfxMessageBox(L"after load library"); And here's the output from gflags (x86)'s loader snaps: 18a0:2a40 @ 06858973 - LdrGetDllHandleEx - ENTER: DLL name: ntdll.dll DLL path: NULL 18a0:2a40 @ 06858973 - LdrGetDllHandleEx - INFO: Locating DLL ntdll

i'm usually using Win32 API in c#.NET. But not declare all in one application. Sometimes usually using user32, sometimes gdi32 ... I think when i declare all api function, those use lot of memory. What is the best way using API in .NET ? Most of the Win32 API is available through managed abstractions. Otherwise, declare the ones you need using DllImport . LoadLibrary should really only be used where you have provided alternate functionality, that is, your application can work even without that particular API function. If the API function is critical, using DllImport will let the loader worry

i have given a chance to my software user to select dll from openfile dialog.(so my user can download dlls form my website and use it with the main project ). everything is working fine and it can even find that dlls is provided by me or selected an invalid dll.but the problem raises if the user selects a renamed file(eg : apple.txt file renamed to apple.dll ). i typed the code like this try dllHandle := LoadLibrary( pwidechar(openfiledialog1.filename)) ; catch { showmessage if it is not a dll (but it can be any dll, it checks this is my dll or 3rd party later )} end; error message shown by

I intend to work with OpenCV 1.1 version and Matlab2011 together. The program uses call to load library. However, it returns an error > In loadlibrary at 347 In Untitled at 4 Error using loadlibrary (line 421) There was an error loading the library "C:\Program Files (x86)\OpenCV1.1\bin\cxcore110.dll" C:\Program Files (x86)\OpenCV1.1\bin\cxcore110.dll is not a valid Win32 application.

Also, on doing

I've a static java library compiled as a jar file. This jar loads a .so library using System.loadLibrary. Then another Android application project links statically the jar file. Everything is compiled using an Android.mk file in the NDK...how can I make the shared native library being included and correctly loaded from my final application (and "seen" from the jar code)? Ok I solved the problem by using these instructions in Android.mk: $(shell cp $(wildcard $(LOCAL_PATH)/libs/armeabi/*.so) $(TARGET_OUT_INTERMEDIATE_LIBRARIES)) LOCAL_JNI_SHARED_LIBRARIES:= libMyLib just before include $(BUILD
