View 4 RepliesI just came upon this article here which can turn your day to day visual basic app to run on mac os x. Here is the link: http://mac.sillydog.org/dev/visual_studio.php The thing I don't get is that the author doesn't tell us specifically what to download, and where to get all the files. He's a bit vague... Can anyone make this clearer to me?
BTW: I am using VB.NET although the author uses C#. I think it will still work though.

I'm trying to write a program which compares the difference between any date in the past and the system date, showing how many days have elapsed since that date.This is what I've got so far:
Code:
Public Class Form1
Private Sub TextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)
End Sub
[code]....
That's what it looks like so far. I was wondering how you can automate the top label so it automatically comes up with the date when the program is run.Plus, I need to know how to display the dates difference (how many days have elapsed between the system date and the user's chosen date) in the bottom label.
I have an Sql server 2005 table called Emploeefl with 2 fields, EmployeeCode and Date of Birth. The data type for the date of birth is Datetime. I have a Date time picker on a vb.net 2005 form called dtDateOfbirth. When I click on the save button I get the error message "Conversion from string 'yyyy/MM/dd' is not valid. Below is the code
Dim newQE_Date As Date
newQE_Date = Format(Me.dtDateOfBirth.ToString, "yyyy/MM/dd")
'newQE_Date = String.Format("2008/09/10", "yyyy/MM/dd")

View 1 RepliesI have a date in the future e.g. 13/10/2008 I need to subtract the current date (today is the 28/09/2010) minus 7 days, so thats 21/09/2010 minus 13/10/2008, which would equal erm, 720 something ? But the current date won't always be 28/09/2010, obviously. I need the code for this. EDIT: When i said future I mean past :)

Is it possible to intercept any program write (to file/registry) commands and prompt the user to allow, while pausing the other program's command? Antivirus thing. I know, this seems impossible. But there must be a way! Even if it's just possible to notice what's happening and save another copy of the to-be-affected file first...

View 10 RepliesI am creating a program that uses text files to recall data and store them in a variable.

View 2 RepliesI have an application that currently stores PDF files (and others) inside the database as BLOBs. The trouble with this method is that I've now got SQL Server databases in excess of 200 GB! I've finally figured out a way to still enable full-text search without needing to store the PDF files as BLOBs (yay! Adobe's iFilter isn't great.), but I'm having trouble designing the method for a client to get access to the files stored on the server's file system.
I want to place the files in a restricted directory on the server, so I can't simply pass a UNC path to the client and let them open the file from there either in a browser or using Process.Start(filename). I understand how that would work, but if that directory has user access granted, all sorts of security holes open up, right?So, what I'm thinking about is a way to have a SQL Server account that has read/write access to/from the protected file system directory. That way (in my mind), the SQL Server can take a file as it's loaded in through the import client (as a series of byte chunks) and write the file to that area of the filesystem. Then, when a file is requested, the SQL Server can bulk load the file into a varbinary(max) field and do whatever I want with it.
1. How can SQL Server take a stream of bytes and write them to a specified location on its local file system? (This is assuming that I want the import utility to be able to be run on a client machine and not require it to be run on the server itself.)
2. Is there any way to stream a varbinary(max) file to a web page out of SQL? I'm using a lot of PDF files that will have Fast Web View enabled, so if I can stream the bytes to a web page, the user will be able to see the first few pages of the document while the rest is loading. I thought about having the SQL Server read (bulk load) the file from the protected area and write it to an unprotected area just long enough to point a web browser to that location, then wiping the file, but that brings me back to #1 above and would THEN require me to be able to issue a delete command from SQL.
