問題描述

您好，我有以下代碼，但沒有按預期工作，無法弄清楚問題出在哪里.

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

基本上，我正在執行一個進程(一個 .NET 進程)并傳遞命令行參數，它由 CreateProcess() 成功執行，但 CreateProcess() 沒有傳遞命令行參數

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

我在這里做錯了什么??

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;
}

嘿還有一件事，如果我像這樣傳遞我的 cmdArgs :

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

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

然后我得到錯誤，然后 CreateProcess 返回 TRUE 但我的目標進程沒有執行.

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

推薦答案

你應該在參數中指定還模塊名稱:LPTSTR cmdArgs = "App name@example.com";它應該是整個命令行(包括 argv[0]).
