Hi, I am developing a windows application which needs word and visio application to be embedded on to a form. I am using DSOFramer Active-X control. My application reads data from the database (a BLOB Field - that contains the word or visio document as byte array) and creates a temporary file in the local directory and then opens that file using DSOFramer control. (http://support.microsoft.com/kb/311765) All the manipulations are stored on the same temporary file and update the file contents on to that database on save (as BLOB). After the temporary file is saved, I am opening the temporary file using IO.FileStream and reading the contents to byte() and updating the database with new binary data(BLOB Field) It works fine most of the time but some times while saving the word document it through an exception - "the target of an invocation" Inner Exception -System.Runtime.InteropServices.COMException (0x80030021): A lock violation has occurred. I hope this explains wat I am trying to do. Please could any one tell me where I am going wrong. Thanks in advance chirantan
I am also working on similar functionality. Please share your code How to open a Word document in DSOFramer?

Hi Bhaskar, you can use the following method to open an existing file. first argument - file (with full path) second arg - determins weather you open in read mode third arg - type of file you are woking with in this case its word document the last two arg - are missing as its is for web based application AxFramerControl1.Open(strFileLocation, False, "Word.Document", Type.Missing, Type.Missing) I hope this helps "Bhaskar" wrote: > I am also working on similar functionality.
