Hi
I have the following bit of code, basically i am selecting a value from a datbase which is showing as 12.00
DateTime dtlogtime = Convert.ToDateTime(readerdate);
if (dttimenow.AddMinutes(1) > dtlogtime)
{
}
the readerdate is a string and is the value from the database
but i get the error message: String was not recognized as a valid DateTime.
any help would be great
thanks

Hi
To me it seems "readerdate" is data reader object. if so ,Convert.ToDatetime does not take a reader obejct as input. Select a pecific column of the reader object what I mean is something like this,
<br />
int i=0;<br />
DateTime dtlogtime = Convert.ToDateTime(readerdate[i]);<br />
if (dttimenow.AddMinutes(1) > dtlogtime)<br />
{<br />
}<br />
<br />
Thanks,
Arindam D Tewary

hi
readerdate being the string value from the database
sorted it
DateTime dtlogtime = Convert.ToDateTime(readerdate);
if (dtlogtime.AddMinutes(1) < dttimenow)
cheers

I am creating application using asp.net and c# and Oracle 10G as database. I am using Nhibernate
When I execeute from query from my page query first time it works fine and also do its job but in the same session if i try to run the same query it is giving me an exception which is
“From Keyword exception”.
The query is written on Command button using a Command button.
I have debugged the code and from the command object I pick up the query and run into SQL developer its running fine.
I also assure as Nhibernate session is also closed.
I also try Global.asax to close the Nhibernate Session.
To start with it looks like session problem which i tried to knock out by closing session, reader, object and also disposing command object.
Any suggestion to resolve this .
Thanks

Hello all,
I've been tinkering with a small Content Management System called ScrewTurnVisualizer that I've found on http://blog.lavablast.com/post/2008/01/Dirt-Simple-ASPNET-CMS-using-the-ScrewTurn-Wiki.aspx
I have converted the code for this short program, which was written in C# to VB with a converter I've found online. When I tried to build and run this program in VS2003, I've got more than 3 dozen error messages. I'm wondering if this CMS is written using dotnet 2.0 and if that is why I've been getting so many error messages. If it was indeed written using dotnet 2.0 could you please show me how to convert it so that it is compatible with VS2003? Below is the code that I've got after the C# conversion to VB. Any help will be greatly appreciated and thank you in advance for your time.

You really can't, because the web browser cannot open other apps.
This is the ASP.NET forum, not ASP.

In ASP.NET, you can only manipulate folders within your server root directory

How can I set resolution of uploaded image and convert it into byte array so that I can store it in database
|
|

The bitmap class's save method has an over load that takes a stream, you can use a buffered stream to end up writing to a byte array.

Hi
I have a web-page which displays details from a database to a user which can be updated.
How can i lock the page to a specific user so that if a different user logs on and tried to access it they can only see a read only version.
any articles or ideas would be great
thanks!!!

You would do this in the DB, you'd store a value to say which user had the lock, and the date/time of the lock, so it can be expired after an appropriate time
