Hi All,
I have intermediate knowledge in VB.Net coding. I have searched the web to find help with
my issue but to no avail. I mean I can't find one that is helpful though there are
some in Web based applications.
I have an urgent issue where I want to store some resumes into a MS SQL Server 2008 DB. I just want to create a windows form application which will have some buttons to upload the resumes into the DB and safe them, and retrive the specific resume from the DB when the name of the person is selected from a combobox, which will contan all the names of the people who's resumes are in the DB.
Senario:
MS SQL Server 2008 DB table will have 2 fields: NameOfResumeOwner, Resume
Windows Form: Will have 2 textboxes and 2 Buttons:
-2 textboxes to hold the ResumeOwner's Name and the Resume to be uploaded
-2 Buttons; 1 to upload/insert data into the DB and the other to Retrive the Resume for editing in MS Word.
my following code for the insertion of the MS Word doc into the DB works fine by inserting the image data but when I want to retrive the data as MS Word doc its not working. Giving the error as Access denied. I have given the necessary permissions to get the MS Word doc to be saved in the location as specified but to no avail. Please assist where possible. (Note: This is Windows Form application and not Web Form Applications as in ASP.Net, so don't point me to ASP.Net sites.)
