Hi, I wrote an application that able to connect another bluetooth device in .Net Framework 2.0 using bluetooth API, now I want to do this with .Net Compact Framework on my mobile device. That's the problem, When I'm Calling Bluetooth API like WSAStartup or using SizeOf or any other methods of Marshal class, it gives me NotSupportedException exception. Please tell me how can i solve this problem. Thank you.

Hi there. have you try this my friends ? if your project is an win32 application project !! i think you can use this configuration : Project menu --> project properties --> configuration properties --> general --> in project defaults group select No Common Language Runtime support for common language runtime support . your application will never need to .net framework

Hi there . I can't call MD5Init() function. in fact i can't initialize MD5 message digest context . here is my code : #include // Declare pattern of function implementation int __stdcall WinMain(HINSTANCE, HINSTANCE, LPSTR, int); int __stdcall WndProc(HWND, UINT, WPARAM, LPARAM); CCoding clsCoding; // // MD5 structure information // typedef struct { ULONG i[2]; ULONG buf[4]; unsigned char in[64]; unsigned char digest[16]; } MD5_CTX; // // The MD5Init function initializes an MD5 message digest context. // typedef void (*MD5Init)(MD5_CTX*); // // The MD5Update function updates the MD5 context by using the supplied buffer for the message whose MD5 digest is being generated // typedef void (*MD5Update)(MD5_CTX*, unsigned char* input, unsigned int inlen); // // The MD5Final function ends an MD5 message digest previously started by a call to the MD5Init function // typedef void (*MD5Final)(MD5_CTX); // ============================== int __stdcall WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd) { // // Handle to the dll file // HINSTANCE hinstLib; // =============================== // Declare variable of type def // MD5Init InitializeMD5; MD5Update UpdateMD5; MD5Final FinalizeMD5; MD5_CTX md5Ctx; // ============================== hinstLib = LoadLibrary(L"Cryptdll.Dll"); // If the handle is valid try to get function address if (hinstLib != NULL) { InitializeMD5 = (MD5Init) GetProcAddress(hinstLib, ("MD5Init")); UpdateMD5 = (MD5Update) GetProcAddress(hinstLib, ("MD5Update")); FinalizeMD5 = (MD5Final) GetProcAddress(hinstLib, ("MD5Final")); // If the function address is valid try call function if (InitializeMD5 != NULL) { (InitializeMD5)(&md5Ctx); (UpdateMD5)(&md5Ctx,(unsigned char*) md5Ctx.in, 10); (FinalizeMD5)(md5Ctx); } } DialogBox(hInstance, MAKEINTRESOURCE(IDD_FORMMAIN), NULL, WndProc); return 0; } Error : Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call. This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention. Where is the problem ?
DMASTER
I know these functions and their usage! but as you know, I should use them AFTER the process is already ran, and (for example) i should use them on the click of a button! the problem is that, my application should be aware of the process start, AS SOON AS THE PROCESS STARTS, and do its job automatically. I'm looking for a method, to make my application aware of the start event FOR ALL THE APPLICATIONS, not just an specific one. Something like a system message (WM_*), which is sent to ALL the applications (including mine) to notify them of a process start.
DMASTER
Dear Hamid, thanks to your reply. But, my question is that, when ever the user runs an application, how can i make a notification of that process start, in my own application. In fact, i want to query the process-start! I wonder if any system message (or any other method) exists, when an application starts?!

Hi there . I have a problem with SqlServer 2005 Log file . I have an application and i want to attach my database to SqlServer , I did it by SqlConnection and ConnectionString ,in many times it gives me an error. I know that when we use AttachDbFilename property in Connection for attach DB we don't need database log file, But most of times it gives me this error: "Unable to open physical file 'filpath_log.LDF'. Operation system error 5: "5(error not found)". Could not open new database 'DbName'. CREATE DATABASE is aborted. Cannot attach the file 'FilPath.mdf' as database 'DbName'. File activation failure. The physical file name 'filpath_log.LDF' may be incorrect. The log cannot be rebuilt when the primary file is read-only.' I wonder to say sometimes attachment works but sometimes not. I already did this attachment process with SQLServer 2000 and it never gives me error .
