createprocess

WinAPI CreateProcess has the flag CREATE_SUSPENDED so it's possible to attach process to JobObject before it has done something and then to call ResumeThread for its main thread. The only that I found searching for a solution is this post written 11 years ago! The only way to do this is with CreateProcess . The .net Process class does not offer the functionality. Either p/invoke CreateProcess or use a mixed mode C++/CLI assembly to call the same. 来源： https://stackoverflow.com/questions/22570591/how-to-create-suspended-process-from-c-sharp-without-p-invoke

This should be an easy one: I am creating a program that spawns a process using the win32 CreateProcess() function. Once this process is loaded, I find its window using FindWindow and send it messages using SendMessage() . The question is, how do I know when that window is ready to accept messages? Consider the following: HWND wnd; BOOL Start() { // Spawn the process if (! CreateProcess(...)) return FALSE; // Find the process's window (class and name already known) wnd = FindWindow(MY_WINDOW_CLASS, MY_WINDOW_NAME); // Always returns FALSE because window has not yet been created. return (wnd !=

Suppose your Windows user account is in the Admin group, UAC is enabled, and you're running some program A with normal user privileges. A never asks for elevation and never receives it. Now suppose A wants to launch program B, which has highestAvailable in its manifest. If A calls CreateProcess(B), this will fail with error 740 ("elevation required") If A calls ShellExecuteEx(B), Windows will display a UAC box asking to run B elevated. The user can say Yes, in which case B will run elevated, or No, in which case the launch will fail. My question is: is there any way to achieve a third option,

The following works just fine in process.start situation. private string Path() { RegistryKey Key = Registry.LocalMachine.OpenSubKey("SOFTWARE\\Wizet\\"); RegistryKey Location = Key.OpenSubKey("MapleStory"); return Location.GetValue("ExecPath").ToString(); } public bool Launch() { maplestory = new ProcessStartInfo(); maplestory.FileName = Path() + @"\MapleStory.exe"; maplestory.Arguments = "WebStart"; MapleStory = Process.Start(maplestory); } Where would I now place the '.Arguments' if I were to use CreateProcess and where would I place CREATE_SUSPENDED as well? CreateProcess(AppName, IntPtr

I'm having a little confusion due to conflicting return values from CreateProcess() and GetLastError() . When I use CreateProcess() in a manner similar to below, it succeeds and appears to accomplish its required tasks. Yet, GetLastError() still returns Access is Denied. If access is denied, why is does it appear to complete the task. In contrast, if CreateProcess() succeeds, why is GetLastError() returning access denied? Or is my use of GetLastError() incorrect? Am I only supposed to use it when CreateProcess() returns a failed value? (My justification for the below behavior was that I

In my Win32 application I have the ability to run child processes with redirected input and output to anonymous pipes that I create and manage - this all works with the CreateProcess() function. However on Win7 (and presumably Vista) if that process is required to be run as administrator then this fails. So what I am looking for is a way to do the equivalent of the "run as administrator" command in explorer that will bring up the standard UAC prompt and then create the process with the elevated permissions. I have seen articles that talk about using the "runas" option to ShellExecute to do

This question already has an answer here: CreateProcess method ends up with an error 1 answer I was reading about CreateProcess function in c++ and I wanted to try it. Basic idea of the code is to have my main execute another process (notepad). Really, it’s just the basic code. When I run the program, I get: First-chance exception at 0x752bb763 in createprocess.exe: 0xC0000005: Access violation writing location 0x00be57b8. Unhandled exception at 0x752bb763 in createprocess.exe: 0xC0000005: Access violation writing location 0x00be57b8. When I make a break point for where the error occurs, I get

I am launching a process from my application using CreateProcess API and I want to bring the window of the new process to top. Is there a way to do it? Do we have any flag or something like that with CreateProcess? You can try to use the STARTUPINFO structure which is passed in with CreateProcess and set SW_SHOW. I'm not sure this will help bring the focus to the top though. If that doesn't work then try the following. First off, do not use FindWindow(), it is unnecessarily unreliable since it only works via the window name and class name. Instead, from your CreateProcess() call you should
