colevariant出问题了
COleVariant FileName(LPCTSTR(_T("f:\\1.doc")));
COleVariant format(WdOpenFormat);


docPrint=docs.Open(&FileName, &ovOptional,
&ovOptional, &ovOptional,
&ovOptional,&ovOptional,
&ovOptional, &ovOptional,
&ovOptional,&ovOptional,
&format, &ovOptional, //11个参数
&ovOptional, &ovOptional,
&ovOptional, &ovOptional);


error C2664: “CDocuments::Open”: 不能将参数 11 从“COleVariant (__cdecl *)(WdOpenFormat)”转换为“VARIANT *”

怎么回事啊。

msdn的参数：

expression.Open(FileName, ConfirmConversions, ReadOnly, AddToRecentFiles, PasswordDocument, PasswordTemplate, Revert, WritePasswordDocument, WritePasswordTemplate, Format, Encoding, Visible, OpenConflictDocument, OpenAndRepair, DocumentDirection, NoEncodingDialog)

COleVariant FileName(LPCTSTR(_T("f:\\1.doc")));
COleVariant format(WdOpenFormat);


docPrint=docs.Open(&FileName, &ovOptional,

&ovOptional, &ovOptional,

LPVARIANT(format), &ovOptional, //

无法解析的外部符号 "class COleVariant __cdecl format(enum WdOpenFormat)" (?format@@YA?AVCOleVariant@@W4WdOpenFormat@@@Z)，该符号在函数 "public: void __thiscall CMyDialog::OnBnClickedButton1(void)" (?OnBnClickedButton1@CMyDialog@@QAEXXZ) 中被引用

[其他解释]

typedef enum {
    wdOpenFormatAuto = 0,
    wdOpenFormatDocument = 1,
    wdOpenFormatTemplate = 2,
    wdOpenFormatRTF = 3,
    wdOpenFormatText = 4,
    wdOpenFormatUnicodeText = 5,
    wdOpenFormatEncodedText = 5,
    wdOpenFormatAllWord = 6,
    wdOpenFormatWebPages = 7
} WdOpenFormat;

这里是我找到的定义，你用其中一个代替WdOpenFormat吧。
