View 1 RepliesThe DB has a field "end date" and 1753/1/1 is supposed to be the value representing nothing, as we cannot assign null to datatime in sql server..
In reporting application the select querry used, gets the data including those 1753 date values. good
Problem 1753 date causes hell with report calculations. there are a lot of calculations in the report and changing the code to ignore 1753 will be a headache, so i was thinking Is there a way to tell sql server,
SELECT *
FROM TABLE BUT IN END_DATE
WHERE VALUE='1753/1/1 01:00:00.000' REPLACE WITH PARAMETER1
CRUDE EDIT (donot have access to debugger currently)
i cannot remember but i get an error like "nothing should be mapped on something" when i insert record with null date! THIS HAPPENS ONLY WHEN USING VB.NET in csharp it works fine. do you know why??
I have VS 2005 installed in my sytem fyi.We have two databases, say source database and destination database. The databases is in Oracle. Now we need to pull data from Source database, manipulate it and push it into the destination database on daily basis.We are planning to use VB .Net for this and would like to know if this is feasible. Using windows forms through VB .NET, is it possible to create a exe and schedule the exe on nightly basis to pull the data from source to destination.how to do this as for manipulation of data, there is no intermediate database for us?
View 1 RepliesI want to manipulate the first name, last name and email via code, preferably server side. But I see this is not really how this might work, using asp hiddenfields for example.
So I have to get the values for the 3 fields server side, and somehow post this to [URL] - do I need to build the script in code and submit that? Not use this javascript?

It's been a while since I've programmed in Visual Basic 6 and very recently nose-dived into Visul Basic 2008 and .NET 3.5 Compact Framework. Hence I'm now becoming a bit stuck. This is NOT homework but a self imposed personal assignment. Only person who will mark it is me, being happy it'll work. Trying to recall and refresh my pprogramming skills the hard way.
I have so far written a program under VB2008 that executed on a WinCE device of which I have to have the terminal connected to the computer as WinCE is not emulated under Visual Studio. I've got the thing reading and writing files on the device using file streams so in a nut shell the sample application I have got working that can write data, find data and amend data.
Now here is where I am becoming stuck. I am now turning my sight on using Microsoft's compact SQL server. To date I have created the data table on the WinCE device using VS2008's data explorer so a database has been created and using the data explorer I can read and write data to the SDF file on the device. (Data Explorer talks to the compact SQL server on the WinCE device via an ActiceSync connection.)
I'm trying to retrieve data from an Access database - a simple one. (Just a single table with one column) My task is to view these records through a 'ListView'. No need to manipulate or anything. Just to retrieve data with a simple SQL statement and display via a ListView.

I have developed a VB.NET program using a strongly typed dataset. This dataset has its connection to a SQL Server 2008 R2. The software should now be additionally used offline. The database should be exported to a *.sdf database. If no connection to the SQL server is produced, the software have to try to connect to the *.sdf database.I would like to achieve:
1. Export the data in the SQL Server 2008 R2 database to a local *.sdf file.
2. This *.sdf file has to work as an alternate connection string in the strongly typed dataset.
How can I write a connection string? I has four different computer that can be connect via ethernet.How can I maintain a inserting data if to computer insert on same table at a single time..??

View 1 RepliesI recently upgraded the MS SQL Server installed on my personal computer from 2005 Express to 2008 Express. Problem is when I try to add an SQL database file to a project using VS 2005 I get an error message saying that the version of my database server is not supported, I must have SQL Server 2005 Beta 2 or later installed. I didn't do it yet but I'm pretty sure that when I open the other projects that I included a database file to it, I'm going to get the same error.
My question is it possible to have two SQL Servers installed on my machine? If so, is it a good idea to have two DB servers in the same machine?

before re-inventing the wheel, i want to ask you how i can do this best: I have a VB.Net application that uses a database connection to MS SQL Server 2005 (express version). There are users that input data with the application into the database lets say once to 2x an hour to once a minute. I want to do backups like this: Once a day or once a week (in the evening) a full backup, and whenever the program/user is idle for lets say 10 Minutes, i want to do an incremental backup (so that it does not take so long until he can work on after the backup).
There are no big security issues, just copying the backup data files to a network share / a different computer or server would be fine. i guess the average db size may be 300MB, but the daily increments about 1MB.

I have developed some software(vb.net) that records fees paid by the students. The purpose is that the database should be stored in a server, which can be accessed from any stations linked with it.This is working fine with a network of 10 computers. I need to publish it over the net so people could do this job logging in over internet. Database (access database) should be stored on a web based server.

View 4 RepliesI am developing an intranet app (so security isn't such a problem). The client wants to drag eml files from Outlook to a folder. I would like put a file watcher control that monitors the folder. When the new file is added I want to run some javascript in the open intranet window. How can the file watcher app communicate with the intranet app (also there may be more than one intranet app open). I am experienced at asp.net but a total novice to Winforms so bear with me.
