c++ - How to Use GetCORSystemDirectory()? -

- 

  हैंडल प्रोक; HMODULE एचडीएलएल; एचडीएलएल = लोड लाइब्रेरी (TEXT ("mscoree.dll")); अगर (एचडीएलएल == नल) cout & lt; & lt; "निर्दिष्ट नाम के साथ कोई डीएलएल" & lt; & lt; endl; Else {cout & lt; & lt; "डीएलएल हैंडल" & lt; & lt; एचडीएलएल & lt; & lt; endl & lt; & lt; endl; Cout & lt; & lt; "प्रक्रिया का पता प्राप्त करना ..." & lt; & lt; endl; Proc = GetProcAddress (एचडीएलएल, "GetRequestedRuntimeVersion"); यदि (Proc == NULL) {फ्री लाइब्रेरी (एचडीएलएल); Cout & lt; & lt; "प्रक्रिया लोड असफल" & lt; & lt; endl; } और {cout & lt; & lt; "प्रक्रिया का पता यहां पाया गया:" & lt; & lt; प्रोक & lt; & lt; एंडएल & lt; & lt; endl; LPWSTR सेंट; DWORD * dwlength; ; डीडब्ल्यूडब्ल्यूएस सीसीबीफर = MAX_PATH; HRESULT एचआर = GetCORSystemDirectory (सेंट, सीसीएच बफर, डीव्लैम्बिल); अगर (एचआर! = नल) {printf ("% s", एचआर); } फ्री लाइब्रेरी (एचडीएलएल); }}

मुझे .NET स्थापना पथ प्राप्त करने के लिए ऐसा करना था, लेकिन मुझे लिंकर त्रुटियां मिल रही हैं।

त्रुटि LNK2019: अनसुलझे बाहरी प्रतीक _GetCORSystemDirectory @ 12 फ़ंक्शन में संदर्भित _Main dot.obj

GetCORSystemDirectory हस्ताक्षर को परिभाषित करें: 

  typedef HRESULT (__stdcall * FNPTR_GET_COR_SYS_DIR) (LPWSTR pbuffer, DWORD cchBuffer, DWORD * dwlength);

फ़ंक्शन पॉइंटर आरंभ करें: 

  FNPTR_GET_COR_SYS_DIR GetCORSystemDirectory = NULL;

mscoree.dll से फ़ंक्शन पॉइंटर प्राप्त करें और उपयोग करें: 

  GetCORSystemDirectory = (FNPTR_GET_COR_SYS_DIR) GetProcAddress (एचडीएलएल, "GetCorSystemDirectory"); अगर (GetCORSystemDirectory! = NULL) {... // GetCORSystemDirectory का उपयोग करें ...}

अनुरोध के रूप में: 

  #ifndef _WIN32_WINNT #define _WIN32_WINNT 0x0600 #endif #include & lt; stdio.h & gt; # शामिल करें & lt; tchar.h & gt; # शामिल & lt; windows.h & gt; टाइपफीफ HRESULT (__stdcall * FNPTR_GET_COR_SYS_DIR) (LPWSTR pbuffer, DWORD cchBuffer, DWORD * dwlength); FNPTR_GET_COR_SYS_DIR GetCORSystemDirectory = NULL; Int _tmain (int argc, _TCHAR * argv []) {हिंसटस एचडीएलएल = लोड लाइब्रेरी (पाठ ("mscoree.dll")); GetCORSystemDirectory = (FNPTR_GET_COR_SYS_DIR) GetProcAddress (एचडीएलएल, "GetCorSystemDirectory"); अगर (GetCorSystemDirectory! = NULL) {टीसीएचएआर बफर [MAX_PATH]; DWORD लंबाई; HRESULT घंटा = GetCORSystemDirectory (बफर, MAX_PATH, और लंबाई); // बफर में फ़ोल्डर का नाम होना चाहिए // इसका इस्तेमाल करना है ..} 0 लौटें; }

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

PHP - get image from byte array -

-
I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
