Windows 如何在“中模拟选择更改”；“文件类型”；GetSaveFileName对话框中的ComboBox是否来自单独的进程？

我正在编写一个自定义模块来使用专有软件。（该软件已停止使用，我没有其源代码。）我的模块将作为单独的进程运行。其目标是通过该专有软件实现操作自动化。为此，我需要能够模拟保存此软件的输出。我可以通过模拟工具栏按钮单击打开其“另存为”对话框：

然后，我尝试将“另存为类型”组合框更改为所需的文件类型，添加要保存到的文件路径，并模拟单击“保存”按钮。我想出了以下代码来实现这一点：

//All I have to work with are the following window handles:

//HWND hWndFileName = file name window handle
//HWND hWndSaveAsType = save as type window handle
//HWND hWndSaveBtn = Save button handle

DWORD dwComboIDSaveAsType = ::GetWindowLong(hWndSaveAsType, GWL_ID);
HWND hParWnd = ::GetParent(hWndSaveAsType);

//Select index for file type
int nSaveAsIndex = 3;
::SendMessage(hWndSaveAsType, CB_SETCURSEL, nSaveAsIndex, 0);
::SendMessage(hParWnd, WM_COMMAND, 
    (dwComboIDSaveAsType & 0xffff) | ((((DWORD)CBN_SELCHANGE) << 16) & 0xFFFF0000),
    (LPARAM)hWndSaveAsType);

//Set path to save
::SendMessage(hWndFileName, WM_SETTEXT, NULL, 
    (LPARAM)L"C:\\Test\\test file");

//Simulate Save button click
::SendMessage(hWndSaveBtn, BM_CLICK, 0, 0);

//我只需要处理以下窗口句柄：
//HWND hWndFileName=文件名窗口句柄
//HWND hWndSaveAsType=另存为类型窗口句柄
//HWND hWndSaveBtn=保存按钮句柄
DWORD dwComboIDSaveAsType=：：GetWindowLong（hWndSaveAsType，GWL_ID）；
HWND hParWnd=：：GetParent（hWndSaveAsType）；
//选择文件类型的索引
int nsavasindex=3；
：：SendMessage（hWndSaveAsType，CB_SETCURSEL，nSaveAsIndex，0）；
：：SendMessage（hParWnd，WM_命令，
（dwComboIDSaveAsType&0xffff）|（（（DWORD）CBN_SELCHANGE）我想我明白了。显然，我还需要将
CBN_SELENDOK
发送给家长。因此应该是这样的：

//All I have to work with are the following window handles:

//HWND hWndFileName = file name window handle
//HWND hWndSaveAsType = save as type window handle
//HWND hWndSaveBtn = Save button handle

DWORD dwComboIDSaveAsType = ::GetWindowLong(hWndSaveAsType, GWL_ID);
HWND hParWnd = ::GetParent(hWndSaveAsType);

//Select index for file type
int nSaveAsIndex = 3;
::SendMessage(hWndSaveAsType, CB_SETCURSEL, nSaveAsIndex, 0);
::SendMessage(hParWnd, WM_COMMAND, 
    MAKEWPARAM(dwComboIDSaveAsType, CBN_SELENDOK),
    (LPARAM)hWndSaveAsType);
::SendMessage(hParWnd, WM_COMMAND, 
    MAKEWPARAM(dwComboIDSaveAsType, CBN_SELCHANGE),
    (LPARAM)hWndSaveAsType);

//Set path to save
::SendMessage(hWndFileName, WM_SETTEXT, NULL, 
    (LPARAM)L"C:\\Test\\test file");

//Simulate Save button click
::SendMessage(hWndSaveBtn, BM_CLICK, 0, 0);

研究的源代码AutoHotKey@DavidHeffernan：对不起，google search给我的结果太多了。你有它的URL吗？这是google上最热门的搜索引擎，它会为你处理这样的细节。因为你似乎在使用标准的文件保存对话框，所以基础结构可用。@IInspectable:对不起，这个主题太宽泛了。你能提供一个与代码示例更相关的参考吗？
