createprocess

问题 On Windows 7, when I used process_create/3 in SWI Prolog to open an application like Notepad.exe, the notepad opens. However, it doesn't work for applications that use command prompt. As an example, when I tried to open the command prompt window, using: main :- process_create('C:\\WINDOWS\\system32\\cmd.exe',[] ,[]). which gives an ERROR: Process "c:\windows\system32\cmd.exe": exit status: 1 Similarly, when trying it to open powershell.exe, it doesn't work either. the console just hangs,

问题 I'm trying to get either CreateProcess or CreateProcessW to execute a process with a name < MAX_PATH characters but in a path that's greater than MAX_PATH characters. According to the docs at: http://msdn.microsoft.com/en-us/library/ms682425.aspx, I need to make sure lpApplicationName isn't NULL and then lpCommandLine can be up to 32,768 characters. I tried that, but I get ERROR_PATH_NOT_FOUND. I changed to CreateProcessW, but still get the same error. When I prefix lpApplicationName with \\?

问题 I'm trying to write a program which needs to create some other processes. I'm used to the Windows API but now I need my program to be able to run in a Linux platform too. Is it possible to do it in a portable manner? Do I have to use the preprocessor for that purpose? EDIT: I need to wait for it to finish before continuing to do things. 回答1: In my opinion the system function should always be avoided: it's unreliable, since you don't know what shell will handle your command and it doesn't have

问题 I am able to create sheets including its name based on a selected list of "names" with the following code (below), BUT when there are cells with repeated name it will create a sheet without a name and the generic "sheet##". I want that if the cell name is repeated or there is a sheet already with that name (same thing) NOT to create a new sheet. Sub AddSheets() Dim cell As Excel.Range Dim wbToAddSheetsTo As Excel.Workbook Set wbToAddSheetsTo = ActiveWorkbook For Each cell In Selection With

问题 OK, this is what I got, I'm using native messaging to fire a c++ program from a chrome extension in Windows. This c++ program (ehost.exe) creates a ffmpeg process for recording the input audio and saving it to mp3. I do this with the CreateProcess() function This works perfect when I open ehost.exe myself (double clicking it) but when I open it from my chrome extension ( chrome.runtime.connectNative() ), the ffmpeg process opens but ffmpeg writes no output file, as if it didn't have

问题 I wrote function CreateProcess( lpApplicationName:String; lpCommandLine:String; lpProcessAttributes:IntPtr; lpThreadAttributes:IntPtr; bInheritHandles:Boolean; dwCreationFlags:Int32; lpEnvironment:IntPtr; lpCurrentDirectory:IntPtr; lpStartupInfo:STARTUPINFO; lpProcessInformation:ProcessInfo):Boolean; external 'kernel32.dll'; but VStudio said "Semicolon" expected - after external and " "end" expected" after 'kernel32.dll'; Can you help me to load and call a function please? 回答1: Why don't you

问题 I use the following STARTUPINFO structure in my call to CreateProcess . Do I need to call CloseHandle on hStdError and hStdInput after the process ends? startupInfo.cb = sizeof(startupInfo); startupInfo.cb = sizeof(si); startupInfo.dwFlags = STARTF_USESTDHANDLES | STARTF_USESHOWWINDOW; startupInfo.hStdInput = GetStdHandle(STD_INPUT_HANDLE); startupInfo.hStdOutput = NULL; startupInfo.hStdError = GetStdHandle(STD_ERROR_HANDLE); startupInfo.wShowWindow = SW_HIDE; 回答1: Since you didn't open those
