我正尝试使用C++ Windows. h的打印假脱机程序API创建一个AddForm函数。我还没有找到任何C++示例或无法找出解决方案，所以我想寻求您的帮助。

我的代码应该与此图片中的代码相同：

• Use PrintSpoolerAPI function SetForm() in C#
  代码输入：

#include <iostream>
#include "Windows.h"
#include "Winspool.h"

using namespace std;

int main() {

    LPHANDLE hPrinter = NULL;
    OpenPrinter(
        NULL,
        hPrinter,
        NULL
    );  // No critical error here: "hPrinter could be "0"

    FORM_INFO_1 exampleform;
    exampleform.Flags = 0;
    exampleform.pName = (LPWSTR)"0A"; // No critical error here: "Cast between semantically different string types. Use of invalid string can lead to undefined behaviour."
    exampleform.Size.cx = 1260 * 1000;
    exampleform.Size.cy = 891 * 1000;
    exampleform.ImageableArea.left = 0;
    exampleform.ImageableArea.top = 0;
    exampleform.ImageableArea.right = exampleform.Size.cx;
    exampleform.ImageableArea.bottom = exampleform.Size.cy;

    cout << exampleform.pName; //output as: "00007FF68EFA9C24"

    AddForm(hPrinter, 1, reinterpret_cast<LPBYTE>(&exampleform)); // No critical error here : "hPrinter could be "0"

    //C:\Users\XXX\source\repos\paperApp\x64\Debug\paperApp.exe (process 16792) exited with code 0.
}

**问题：**代码看起来不错，但实际上什么也没发生。

谢谢大家的回复！
