c++ - 检查 PC 上是否安装了 Outlook

Question

有没有一种方法可以让我以编程方式检测 MicrosoftPC 上安装了 Outlook(任何版本)。我必须在非托管 C++ 中执行此操作。

Answer 1

在 MSDN is an example of how to detect Outlook 版本(或者如果安装了 Outlook)。下面是该示例的美化版本:

#include <Windows.h>
#include <Msi.h>

#include "stdafx.h"

static int compareOutlookVersion(const TCHAR* exe)
{
    const TCHAR outlookRegister[][MAX_PATH] = {
        TEXT("{E83B4360-C208-4325-9504-0D23003A74A5}"), // Outlook 2013
        TEXT("{1E77DE88-BCAB-4C37-B9E5-073AF52DFD7A}"), // Outlook 2010
        TEXT("{24AAE126-0911-478F-A019-07B875EB9996}"), // Outlook 2007
        TEXT("{BC174BAD-2F53-4855-A1D5-0D575C19B1EA}")  // Outlook 2003
    };
    const int outlookVersions[] = {
         2013,
         2010,
         2007,
         2003 
    };
    DWORD pathLength = 0;

    for (int i = 0; i < (sizeof(outlookVersions) / sizeof(outlookVersions[0])); i++)

    if (ERROR_SUCCESS ==
        MsiProvideQualifiedComponent(
            outlookRegister[i],
            exe,
            (DWORD) INSTALLMODE_DEFAULT,
            NULL,
            &pathLength
        )) {
        return outlookVersions[i];
    }

    return 0;
}

int getOutlookVersion(int* bits)
{
    int version;

    *bits = 32;
    version = compareOutlookVersion(TEXT("outlook.exe"));
    if (version) {
        return version;
    }

    *bits = 64;
    version = compareOutlookVersion(TEXT("outlook.x64.exe"));
    if (version) {
        return version;
    }

    *bits = 0;
    return 0; // No Outlook found.
}

int _tmain(int argc, _TCHAR* argv[])
{
    HRESULT result;
    int version;
    int bits;

    version = getOutlookVersion(&bits);

    if (version) {
        printf("Outlook %d, %d bit\n", version, bits);
    } else {
        printf("No Outlook found.\n");
    }

    return 0;
}
