如下如所示，*.dll 或者*.exe文件的版本號分兩部分.
第一部分是數(shù)值形式的版本號，而第二部分是資源中的文字字符串。
下面的代碼做為修改版本號的參考
typedef?struct?_tagLanguage
 
{
 ????WORD?wLanguage;
????WORD?wCodePage;
 }
tagLanguage,?
*
LPLanguage;
struct?VS_VERSIONINFO
{
????WORD????????????????wLength;
????WORD????????????????wValueLength;
????WORD????????????????wType;
????WCHAR???????????????szKey[
1
];
????WORD????????????????wPadding1[
1
];
????VS_FIXEDFILEINFO????Value;
????WORD????????????????wPadding2[
1
];
????WORD????????????????wChildren[
1
];
}
;

對于資源中的文本類型的版本號，如FileVersion, ProductVersion, 修改的字符串長度不能超過原長度。如果不足的話末尾用'\0‘填不滿。 所以，在編譯的時候，盡量在資源中設置一個長一點的字符串來占位，免得到時候修改的時候空間不足。
