View 1 Repliesi have been coding for years, but never integrated XML. So I guess I'm a newbie. I have inserted an XSD file in my project, ARequest.xsd. I created a folder in my project called XML just to organize things, so this file ARequest.xsd, is in this folder.
Now I have a form that displays data from a database that has the same fields that are in this XSD file. Can I load the XSD file into my Windows Form, load the elements from the data on the windows form and then create an XML file then send it? If so how? Any code snippets would be helpful. Now I do know how to create the XML file, we'll call it Test as

I saved a file with the extension .doc. I use the RichText to write and save the text. I did not set any encoding type when I saved it. When I tried to open the file in the Richtextbox again, I got all the formatting characters in the RTF file. How do I correct this? How do I open and re-open a .doc file in the Rich Text box control without the formatting showing up in the box with the document contents?

I have referenced this thread and the website it points to:pening a file in my application from File ExplorerAs of now, I can't get My.Application.CommandLineArgs to work properly. Any time I select an file to open in my program I get a windows error forcing the program to close. I only want to get the file path from My.Application.CommandLineArgs and pass it to a function that will then parse the file (a text file of various extensions, even if it is not associated with my program) and display the contents in a RichTextBox.My function to open the file is complete and works, but if I try to use My.Application.CommandLineArgs on a file the program crashes immediately.here is the code I'm trying as a test:

I have a program I made in vb.net express 2008 that used java.utils.zip to compress my work files to a Zip archive that I ran occassionaly to have a backup. I worked fine, but with net framework 4 and vb.net 2010 it doesn't work. So I modified it to use sharpziplib and it works fine if all files on the filter list in the folder are closed, but if I have a file open in OpenOffice writer, my program can't access it and won't create the zip file. The file that usually stays open all the time is my TODO list, that is updated several times a day , so usually gets printed, and updated( adding or deleting entries), without closing it.
