CreateProcess 不传递命令行参数

2021-12-18 00:00:00 winapi c++ createprocess

您好，我有以下代码，但没有按预期工作，无法弄清楚问题出在哪里.

Hello I have the following code but it isn't working as expected, can't figure out what the problem is.

基本上，我正在执行一个进程(一个 .NET 进程)并传递命令行参数，它由 CreateProcess() 成功执行，但 CreateProcess() 没有传递命令行参数

Basically, I'm executing a process (a .NET process) and passing it command line arguments, it is executed successfully by CreateProcess() but CreateProcess() isn't passing the command line arguments

我在这里做错了什么??

What am I doing wrong here??

int main(int argc, char* argv[])
{
    PROCESS_INFORMATION ProcessInfo; //This is what we get as an [out] parameter

    STARTUPINFO StartupInfo; //This is an [in] parameter

    ZeroMemory(&StartupInfo, sizeof(StartupInfo));
    StartupInfo.cb = sizeof StartupInfo ; //Only compulsory field

    LPTSTR cmdArgs = "name@example.com";

    if(CreateProcess("D:\email\smtp.exe", cmdArgs, 
        NULL,NULL,FALSE,0,NULL,
        NULL,&StartupInfo,&ProcessInfo))
    { 
        WaitForSingleObject(ProcessInfo.hProcess,INFINITE);
        CloseHandle(ProcessInfo.hThread);
        CloseHandle(ProcessInfo.hProcess);

        printf("Yohoo!");
    }  
    else
    {
        printf("The process could not be started...");
    }

    return 0;
}

嘿还有一件事，如果我像这样传递我的 cmdArgs :

Hey one more thing, if I pass my cmdArgs like this:

// a space as the first character
LPTSTR cmdArgs = " name@example.com";

然后我得到错误，然后 CreateProcess 返回 TRUE 但我的目标进程没有执行.

Then I get the error, then CreateProcess returns TRUE but my target process isn't executed.

Object reference not set to an instance of an object

推荐答案

你应该在参数中指定还模块名称:LPTSTR cmdArgs = "App name@example.com";它应该是整个命令行(包括 argv[0]).

You should specify also the module name in parameters: LPTSTR cmdArgs = "App name@example.com"; It should be the whole command line (including argv[0]).
