[c++] 執行 command line 並取得執行結果
http://stackoverflow.com/questions/478898/how-to-execute-a-command-and-get-output-of-command-within-c 用 popen (open pipe)執行 command, 並用 fgets 收結果。如果是在 windows 上，則是改用 _popen, _pclose #include <string> #include <iostream> #include <stdio.h> std::string exec(char* cmd) { FILE* pipe = popen(cmd, "r"); if (!pipe) return "ERROR"; char buffer[128]; std::string result = ""; while(!feof(pipe)) { if(fgets(buffer, 128, pipe) != NULL) result += buffer; } pclose(pipe); return result; }
3ds Max maxscript import and export issues, and solutions (with simulating user clicking on buttons) 匯入與匯出問題與解決方法(模擬使用者按下按鈕)
In 3ds Max, users can import and export via UI. In batching process, we utilize scripting to largely reduce users’ interactions with calling “importFile” and “exportFile”. These two function calls provides “#noPrompt” option for “silently” processing. However, this “#noPrompt” mode is a bit different to “prompt” mode, “functionally”. We more focus on export in this […]
2D Range Value Picker / 二維值選取控制器
如果是一般的 range value 選取, 還可以用 scrollbar 之類的東西蒙混過去。但二維值就不行了，maxscript 的 default ui controllers 沒這樣的東西, 而 .net default windows form controllers 也沒這樣的東西, 所以只好自己動手做…

3ds Max Script loading User Library (.net)
記錄一下 Assembly = dotNetClass “System.Reflection.Assembly” Assembly.loadfrom (“D:/user/library/path/file.dll”) test = dotNetObject “dll_namespace.class_name”
3ds Max Script socket receving data via .net api
做個紀錄 socket = dotNetObject “System.Net.Sockets.Socket” (dotnetclass “System.Net.Sockets.AddressFamily”).InterNetwork (dotnetclass “System.Net.Sockets.SocketType”).Stream (dotnetclass “System.Net.Sockets.ProtocolType”).Tcp socket.connect ip_address port buf = DotNetObject “System.Byte[]” 1000 fn doFaceShiftSocket = ( try ( while socket.Connected == true do ( socket.Receive buf ) ) catch ( — do nothing ) ) thread = dotNetObject “system.componentModel.backgroundWorker” dotnet.addEventHandler thread “DoWork” doFaceShiftSocket thread.WorkerSupportsCancellation = true thread.runWorkerAsync() for […]
C++ union 就是要用在這種地方啊…
喵的，以前學的時候都不知道 union 可以在什麼地方用到，原來這樣的用途才是王道… union { float f; uchar b[4]; } u; u.b[3] = b0; u.b[2] = b1; u.b[1] = b2; u.b[0] = b3; return u.f; Ref: http://stackoverflow.com/questions/3991478/building-a-32bit-float-out-of-its-4-composite-bytes-c
