expression.Open(FileName, UpdateLinks, ReadOnly, Format, Password, WriteResPassword, IgnoreReadOnlyRecommended, Origin, Delimiter, Editable, Notify, Converter, AddToMru, Local, CorruptLoad)
expression A variable that represents a Workbooks object.
|FileName||Optional||Variant||String. The file name of the workbook to be opened.|
|UpdateLinks||Optional||Variant||Specifies the way links in the file are updated. If this argument is omitted, the user is prompted to specify how links will be updated. For more information on the values used by this parameter, see the Remarks section. If Microsoft Excel is opening a file in the WKS, WK1, or WK3 format and the UpdateLinks argument is 2, Microsoft Excel generates charts from the graphs attached to the file. If the argument is 0, no charts are created.|
|ReadOnly||Optional||Variant||True to open the workbook in read-only mode.|
|Format||Optional||Variant||If Microsoft Excel is opening a text file, this argument specifies the delimiter character. If this argument is omitted, the current delimiter is used. For more information on the values used by this parameter, see the Remarks section.|
|Password||Optional||Variant||A string that contains the password required to open a protected workbook. If this argument is omitted and the workbook requires a password, the user is prompted for the password.|
|WriteResPassword||Optional||Variant||A string that contains the password required to write to a write-reserved workbook. If this argument is omitted and the workbook requires a password, the user will be prompted for the password.|
|IgnoreReadOnlyRecommended||Optional||Variant||True to have Microsoft Excel not display the read-only recommended message (if the workbook was saved with the Read-Only Recommended option).|
|Origin||Optional||Variant||If the file is a text file, this argument indicates where it originated (so that code pages and Carriage Return/Line Feed (CR/LF) can be mapped correctly). Can be one of the following XlPlatform constants: xlMacintosh, xlWindows, or xlMSDOS. If this argument is omitted, the current operating system is used.|
|Delimiter||Optional||Variant||If the file is a text file and the Format argument is 6, this argument is a string that specifies the character to be used as the delimiter. For example, use Chr(9) for tabs, use "," for commas, use ";" for semicolons, or use a custom character. Only the first character of the string is used.|
|Editable||Optional||Variant||If the file is a Microsoft Excel 4.0 add-in, this argument is True to open the add-in so that it’s a visible window. If this argument is False or omitted, the add-in is opened as hidden, and it cannot be unhidden. This option doesn't apply to add-ins created in Microsoft Excel 5.0 or later. If the file is an Excel template, True to open the specified template for editing. False to open a new workbook based on the specified template. The default value is False.|
|Notify||Optional||Variant||If the file cannot be opened in read/write mode, this argument is True to add the file to the file notification list. Microsoft Excel will open the file as read-only, poll the file notification list, and then notify the user when the file becomes available. If this argument is False or omitted, no notification is requested, and any attempts to open an unavailable file will fail.|
|Converter||Optional||Variant||The index of the first file converter to try when opening the file. The specified file converter is tried first; if this converter doesn’t recognize the file, all other converters are tried. The converter index consists of the row numbers of the converters returned by the FileConverters property.|
|AddToMru||Optional||Variant||True to add this workbook to the list of recently used files. The default value is False.|
|Local||Optional||Variant||True saves files against the language of Microsoft Excel (including control panel settings). False (default) saves files against the language of Visual Basic for Applications (VBA) (which is typically US English unless the VBA project where Workbooks.Open is run from is an old internationalized XL5/95 VBA project).|
|CorruptLoad||Optional||XlCorruptLoad||Can be one of the following constants: xlNormalLoad, xlRepairFile and xlExtractData. The default behavior if no value is specified is xlNormalLoad and does not attempt recovery when initiated through the OM.|
A Workbook object that represents the opened workbook.
By default, macros are enabled when opening files programmatically. Use the AutomationSecurity property to set the macro security mode used when opening files programmatically.
You can specify one of the following values in the UpdateLinks parameter to determine the delimiter character for the file:
|1||User specifies how links will be updated|
|2||Never update links for this workbook on opening|
|3||Always update links for this workbook on opening|
You can specify one of the following values in the Format parameter to determine the delimiter character for the file:
|6||Custom character (see the Delimiter argument)|
This example opens the workbook Analysis.xls and then runs its Auto_Open macro.
