在 C++ 中设置项目自定义操作“[TARGETDIR]”

发布于 2024-09-08 19:19:52 字数 780 浏览 7 评论 0原文

我正在尝试将文件复制到安装目标目录中。

我正在使用这个：

TCHAR destPath[ MAX_PATH ] = &L"[TARGETDIR]";
wcscat_s(destPath, L"[email protected]\\Capture.png");
CopyFile(L"C:\\Users\\waldek\\Desktop\\Capture.png", destPath, 0);

如果我使用这个：

CopyFile(L"C:\\Users\\waldek\\Desktop\\Capture.png", L"C:\\Program Files (x86)\\Microsoft\\Setup1\\[email protected]\\Capture.png", 0);

它可以工作，这基本上就是 destPath 应该评估的内容，我可以看到它在我使用 PMSIHANDLE 时进行评估，它会提醒正确的路径...

我如何强制 CopyFile 评估“[目标目录]";

I am trying to copy file into the setup target directory.

I am using this:

TCHAR destPath[ MAX_PATH ] = &L"[TARGETDIR]";
wcscat_s(destPath, L"[email protected]\\Capture.png");
CopyFile(L"C:\\Users\\waldek\\Desktop\\Capture.png", destPath, 0);

if I use this:

CopyFile(L"C:\\Users\\waldek\\Desktop\\Capture.png", L"C:\\Program Files (x86)\\Microsoft\\Setup1\\[email protected]\\Capture.png", 0);

it works, which is basically what destPath should evaluate to, I can see that it evaluates when I use PMSIHANDLE, it alerts the correct path...

How do I force CopyFile to evalue "[TARGETDIR]";

WCHAR vbuff [MAX_PATH] = {0};

DWORD vlen = MAX_PATH;
UINT gp = MsiGetPropertyW(hInstall, L"CustomActionData", vbuff, &vlen);

在属性 CustomactionData 中的安装自定义操作中，我只是将 [TARGETDIR]

vbuff 放在目标目录中，

然后当然是按预期执行串联和 FileCopy...

这对我有用...但我仍然想知道为什么，它没有出现在我发布的原始问题中，最奇怪的是 PMSIHANDLE 写出了正确的路径，但我猜想在 FileCopy 函数中传递它时缺少“翻译”步骤......

我确信我错过了关于这一点的一些理论。

WCHAR vbuff [MAX_PATH] = {0};

DWORD vlen = MAX_PATH;
UINT gp = MsiGetPropertyW(hInstall, L"CustomActionData", vbuff, &vlen);

in the Install Custom Action in property CustomactionData, I just put [TARGETDIR]

vbuff is the target directory

then of course the concatenation and the FileCopy executed as expected...

this worked for me... but I still would like to know why, it didn't in the original question I posted, the strangest thing was that the PMSIHANDLE wrote out the correct path, but I guess there "translation" step was missing in passing it in the FileCopy function...

I am sure I am missing some theory on this.

假设这是自定义操作的一部分，您可以使用 MsiFormatRecord。省略了错误处理，它看起来像这样：

PMSIHANDLE hRec = MsiCreateRecord(1);
MsiRecordSetString(hRec, 0, _T("[TARGETDIR][email protected]"));

TCHAR szPath[MAX_PATH] = {0};
DWORD cchPath = MAX_PATH;
MsiFormatRecord(hInstall, hRec, szPath, &cchPath);

Assuming this is part of a custom action, you can use MsiFormatRecord. Error handling omitted, it would look something like this:

PMSIHANDLE hRec = MsiCreateRecord(1);
MsiRecordSetString(hRec, 0, _T("[TARGETDIR][email protected]"));

TCHAR szPath[MAX_PATH] = {0};
DWORD cchPath = MAX_PATH;
MsiFormatRecord(hInstall, hRec, szPath, &cchPath);
