I use the following function to test whether a string is alphanumeric. If it does not contain any of these characters, then it will display an error. Now I have an error with the element because I pressed enter a couple of time, and it doesn't pick it up here? How do I enter the enter character in the function below? I hope you understand. This a valid text Good moring, but when I do the following then there is an error,

for(i = 0; i < str.length; i++)
{
if(!( ((str.charAt(i) <= '9') && (str.charAt(i) >= '0')) ||
((str.charAt(i) <= 'z') && (str.charAt(i) >= 'a')) ||
((str.charAt(i) <= 'Z') && (str.charAt(i) >= 'A')) ||
(str.charAt(i) == ' ') || (str.charAt(i) == '-') ||

Does checking for a carriage return (char 13) work?
e.g.
if (..... &&(str.CharAt(i) == 13)

If I have an empty textbox, and the related field in the database table does not require a value, is better to write the value as '', or should I enter a NULL value? If the value is to be written as a NULL value, how do I convert the empty textbox field into a NULL value in my SQL string? I use Request.Form("txtDescription") to retrieve the value, but how do I test and convert it into one line, is this possible?
Your help and time is appreciated!!!
Thanks

That depends on your datamodel. A NULL value is typically defined as meaning an absence of data. Whereas an empty string could mean that there is data and it was an empty string.
I read recently, although I've not tested this myself, that adding NULL values to a database slows it down and so should be only used where necessary. In other words you should only use it if you genuinely have a need to represent a gap in the data.
There is a System.DBNull[^] class in the .NET Framework to represent Null values in a database.
When you create your SQL Command you assign DBNull.Value to the relevant parameter. When you read data from the database you need to check the object being returned to see whethere it is a DBNull.Value before doing anything else with it. This adds extra steps to the process when you read and write data to the database.
If you still can't decide one way or the other: I would say that for a description field, an empty string would be better than a null value.

I use the GetRows() method to work with my fields retrieved from a table query in ASP.
After I open the recordset, I do the following:
If Not objRs.EOF Then
arr = objRs.GetRows()
End If
I have 3 questions with regards to using the GetRows() method:
1. arr is used as an array. I don't have much experience with arrays. Must they be set to nothing when I have finished using it? Something like Set arr = Nothing
2. I was told to do what is necessary with the recordset and to close it ASAP. If I return one row from the table, can I use the recordset to populate my fields, or should I rather assign it to an array like I did above? I just need to know when is it most appropriate to use the GetRows() method, only when many rows are returned, or for a few rows as well?
3. How would I do this same thing in Visual Basic 6? I don't know how to declare an array in VB6.
Your help and time is appreciated!!!
Thanks

We have an on-line computer support site that resides on our server and is accessed via our Intranet. Our employees use it to submit computer related problems to our IT personnel. One of the required fields they must input is their local computer name. Unfortunately, most of our employees have NO idea how to obtain this information.
I would like to have a script that will automatically pull thier local computer name and input it into the "computer name" field on said page.
I've been unsuccessful scouring the web for such a beast, if anyone has the complete code and is willing to share, I would appreciate it very much.
Thank you!

See the Win32 API function GetComputerName(LPSTR ComputerName, DWORD *dwpSize);
You can write a module around this function (Browser Helper Obj, COM component, ActiveX, etc.) and have it installed on the client's computer.
onwards and upwards...

creating a standard cookie file from
a .exe application, that will later
be consumed by a intranet
application via the ie browser.
(I'd like to be able to generate
client side cookie files without without actually

In the application, I am using two windows (parent and child). On session expiry, the child window which is the current one is redirecting the user to the login page by using the following code.
if (session("UserName") = "") then
Response.Redirect("expire.asp")
end if
At this time, I want to close the parent window. How can I do this. Please help !!

You can't from the server side
|
|
|
|

Mark is right - you'll have to have some client side javascript to take care of that parent window. A simple parent.close() should do it. (Taking that from memory - probably won't work  Make sure to check if the parent window is there, otherwise you'll get an error from the login page when first going to it.
