Office Viewer Component

You can disable or delete the context menu item in MS Word or Excel by VBA programming.

Word:

OA1.CreateNew “Word.Document”
Set objWord = OA1.ActiveDocument
objWord.Application.CommandBars(”Text”).Controls(”Cu&t”).Enabled = False
objWord.Application.CommandBars(”Text”).Controls(”&Copy”).Enabled = False
objWord.Application.CommandBars(”Text”).Controls(”&Paste”).Enabled = False
‘delete item directly
‘objWord.Application.CommandBars(”Text”).Controls(1).Delete
‘objWord.Application.CommandBars(”Text”).Controls(2).Delete ….

Excel

OA1.Open “c:\text.xls”
Set objExcel = OA1.ActiveDocument
objExcel .Application.CommandBars(”Cell”).Controls(”Cu&t”).Enabled = False
objExcel .Application.CommandBars(”Cell”).Controls(”&Copy”).Enabled = False
objExcel .Application.CommandBars(”Cell”).Controls(”&Paste”).Enabled = False
‘delete item directly
‘objExcel .Application.CommandBars(”Cell”).Controls(1).Delete
‘objExcel .Application.CommandBars(”Cell”).Controls(2).Delete ….

If you are developing the destop application with the office viewer component, you can use the “IsDirty” method to verify whether the open document is modified. When the open file has any modification, the IsDirty method return TRUE. After you save the document, the IsDirty return False again.

But if you are developing the web application, you need to add some extra codes. Because you are opening a file from remote server and the component can’t watch the file like destop application.

A good method is set another variable in your application. When you save the document, you set the variable true. Any time you can judge the dirty by the IsDirty method and your own variable.

BOOL GetIsDirty(){

if(OA.IsDirty()==Flase) return False;

else return m_bDirty;

}

The Office Viewer Component provides the method “EnableFileCommand” to allow the developers to disable the File command in the MS office program.

If you are developing a web application, you can set the initial functions in the “NotifyCtrlReady” event.

function OA1_NotifyCtrlReady() {
document.OA1.EnableFileCommand(0) = false; //FileNew = 0
}
<SCRIPT LANGUAGE=javascript FOR=OA1 EVENT=NotifyCtrlReady>
<!–
OA1_NotifyCtrlReady();
//–>
</SCRIPT>

More File Command ENUMS:

typedef enum FileCommandType
{
FileNew = 0,
FileOpen,
FileClose,
FileSave,
FileSaveAs,
FilePrint,
FilePageSetup,
FileProperties,
FilePrintPreview
} FileCommandType;

When you call a method that has optional parameters from Visual C++, you cannot omit the optional parameters. You need to pass a special VARIANT instead.

Some methods have “optional” parameters. In Visual Basic, you can omit them when calling the method. However, when calling with Visual C++, you have to pass a special VARIANT whose .vt field has the value VT_ERROR and .scode field has the value DISP_E_PARAMNOTFOUND. That is:

VARIANT varOpt;
varOpt.vt = VT_ERROR;
varOpt.scode = DISP_E_PARAMNOTFOUND;
OfficeViewer1.OfficeProtectDocument(varOpt);

If you would like to hide the EDraw Office Viewer ActiveX Control in runtime, you need call the “OfficeObjectVisable” method.

For example: axOfficeViewer1.OfficeObjectVisable = false;

The follow code will lead to an error in C#.

axOfficeViewer1.Dock = System.Windows.Forms.DockStyle.Fill;
axOfficeViewer2.Visible = false;
axOfficeViewer3.Visible = false;
