You can host multiple office component in a form or you can open multiple office instance in your internet explore with Edraw Viewer Component version 7.

The new version 7 has no toolbar-locked issues with multiple instances of Word or excel opened in several tabs or even inside single form.

Note: you need set the Frame hook policy as SetOnFirstOpen and Component activation policy as KeepUIActiveOnAppDeactive in the previous version. But it doesn’t work for the IE7 or IE8.

Frame hook policy
To correctly handle activation when the host gains or loses foreground status, the ActiveX control uses a frame hook. By default, the hook is set when the control is created. In some situations, especially when the control is used from a multi-threaded UI host or when the control is nested in a container control like a Tab page in a .NET WinForm application, the parent of the control at create time may not be the correct window for the control to hook when it is running. In these situations, you can use the FrameHookPolicy property to reset the hook at a more suitable time. For example, if you build a .NET WinForm solution, set the FrameHookPolicy property to SetOnFirstOpen in the Properties window.

Component activation policy
The sample control can support more than one instance of itself in a given host application. However, only one control can be active at a given time. This is a requirement of ActiveX Document hosting. To handle multiple instances in a single host, the control registers itself with a component manager. This lets the component manager keep track of the active control. Use the ActivationPolicy property to control how the embedded object is handled during component changes. The ActivationPolicy property can be set to one or more of the bit flags that are defined by the ActivationPolicy enumeration.

The DSOFramer VC++ Control is released provided by Microsoft to demonstrate how to host Office documents in VB or HTML. As a COM component, it can also be invoked inside .net applications. Unfortunately MS does NOT guarantee any support as it is provided as an example only. The component has lot’s strange problems and is difficult for users to solve. The component is aslo not script safe for initialization and safe for scripting. Some typical bugs in it are impossible. You can find multiple excel processes keep in the task manager when you exit your program. You can find the component popup some memory error when it works in IE8. It also impossible to load a Word document when the web page load automatically. The component will failed to create New document twice consecutively. The component won’t work in the Vista UAC enable environment.

All these will spend lot’s of time to overtime. Why not use the Edraw Office Viewer Component? You can think it’s a enhenced dsoframer and easily get better product support than others. It has some new features to help get the read only property and the http stream support. It is safer because it is code sign and site lock support. The savetoserver method used the http post method and won’t be blocked by the firewall. You can download the trial version from http://www.ocxt.com/download/OfficeOCXSetup.exe

Now you can call the follow scripts to finish the SaveToServer.

Sub SavetoServer()
    If OA1.IsOpened = True Then
     document.body.style.cursor = “wait”
     OA1.HttpInit
     Dim strFileName
     strFileName = OA1.DocumentName
     If strFileName = “” Then
        strFileName = “yourguid”
        strFileName = strFileName + OA1.GetOpenedFileExt()
     End If
      OA1.HttpAddPostOpenedFile strFileName
      OA1.HttpPost “http://www.ocxt.com/demo/upload_weboffice.php”
      document.body.style.cursor = “default”
      Dim sPath
      On Error Resume Next
      sPath = “Save successfully! You can download it at http://www.ocxt.com/demo/” + strFileName
    MsgBox sPath
 Else
  MsgBox “Please open a document firstly!”
 End If
End Sub

2. Adds some new methods.

Function:  HRESULT GetTempFilePath([out,retval] BSTR* strValue);
Description: Gets a temporary file path.

Function:  HRESULT ClearTempFiles();
