Strange txtbox errors

Jim in Arizona · Aug 26, 2005

I'm going insane! I don't know if it's just that the .net 2.0 framework is
buggy or if it really is my code.

This is pretty hard to explain since I can't even begin to nail down why
this is happening.

I have two text boxes. One is for the ID number, which when postback occurs,
inserts into the related table as the foreign key.
The other text box is for notes that go along side the foreign key of the
the related table. Basically, the SQL statement looks like this:

strSQL2 = "INSERT INTO TNotes (FK,notes,unnotes,dtnotes) VALUES ('" & _
txtID.Text & "','" & txtNotes.Text & "','" & strFixedName & _
"','" & Now() & "')"

This statement is called on a few different events: when a button called
"Post Note" is clicked and when a dropdownlist is changed.

How can it be possible that this will work when the Post Note button is
clicked some times, but not work others? It's the same code that's execute
with the same controls in operation on the webform.

When I response.write the SQL statement, I see that the text from the txtID
textbox is not being included within the SQL statement. Neither is the text
from the txtNotes textbox, so my SQL statement ends up looking like this:

INSERT INTO TNotes (FK,notes,unnotes,dtnotes) VALUES ('','','Jim','8/25/2005
4:48:22 PM')
Instead of
INSERT INTO TNotes (FK,notes,unnotes,dtnotes) VALUES ('35','This is a test
note','Jim','8/25/2005 4:48:22 PM')

Something similar to this was happening with another button where the text
from the txtID textbox was not being included wtihin the SQL statement when
logically it should have. I got frustrated and just deleted the entire
button1_click subprocedure and was going to start over with it later on
after got some more coding done. That's when I came across the other problem
mentioned above.

If anyone would like to see the full set of code, not a problem.

If it helps any, here was the error I was getting (before i did a try/catch
and placed a response.write to see what the sql statement looked like). Of
coruse, this would, I think, happen if there was data missing like I showed
in the above SQL statement. TIA for any helpful clues as to this unusual
problem.

well, the trapped error appears to be due to adding an item to a table
where the referenced key value doesn't exist in the related table...
but if you are getting a fouled up insert query that would explain that
error.

as for full code, yes, that would be helpful to get a handle on what is
happening -- can you please give us the aspx and aspx.vb source?

a comment on the technique... it would be safer and more efficient to
write a stored procedure to do this insert and to pass the inserted
values as parameters to the procedure (this gives the advantage of
pre-compilation of the script and reduces the risk of malicious script
being appended (e.g. theValueYouExpect; DELETE FROM tableName))

I'm still pretty much a newbie. I did some classic ASP before moving on to
ASPNET and I've found ASPNET to be much easier to work with. As far as
stored procs, I haven't yet learned much about them. I know you can call
them (I called a query from access) but I don't know how to write them and
my TSQL skills are novice. I'm learning though.

I'm currently trying to figure out my error by going line by line through my
code. I still don't know how a button even can work normally at one point
and not work normally at another point when the code does the same thing.

My SQL database has five tables: two tables that are related and three
tables used to populate three dropdownlists. This application is a system
which employess use our internal website to report computer problems. They
post their problem via a web form. Then, the information systems staff
(myself and a few others) use another webform to view these 'tickets', post
messages to them, set a priorty, mark them resolved then mark them approved.

Since the three lookuptables are not relevant, I won't bother mentioning
them further. Here's the two related tables, in sql create table terms.:

CREATE TABLE TTickets (
PK INT IDENTITY PRIMARY KEY,
subject varchar(40), --Is from a DDL that puts in type of
problem
descript varchar(5000), -- the employee's long winded narrative
of the problem
name varchar(50), -- the employee's name that they give
unemp vachar(50), --the empoyee's username from active
directory
dtemp smalldatetime, --the Now() function used to insert
datetime
ip varchar(14), --IP Address of employee's computer
assign varchar(50), --Technicians name that the ticket is
assigned to
unass varchar(50), --The assigning person (could be self or
another tech)
dtass smalldatetime, --The Now() function used to set
datetime of assignment
resolve bit, --Marked 1 if ticket has been resolved
unresolve varchar(50), -- Name of the tech who resolved the ticket
dtresolve smalldatetime, --Now() used to insert datetime for when
ticket was resolved
approve bit, -- Marked 1 if ticket has been approved after being
resolved
unapp varchar(50), --Person's name who approved the ticket
dtapp smalldatetime, --Now() used to set datetime when ticket
was approved
prioritycolor varchar(8), --Hex color code for priority. Makes
everything look like a xmas tree!
prioritynumber smallint, --Priority number. Value between 0 and 6 (1 to 5
used)
disregard bit, --Marked 1 if ticket was so trivial as to not be
concerned with
undisregard varchar(50), --Tech who marked ticket as disregarded
dtdisregard smalldatetime, --When the ticked was marked disregarded
)

CREATE TABLE TNotes (
PK INT IDENTITY PRIMARY KEY,
FK INT, -- This is the FOREIGN KEY to PK in TTickets
notes varchar(5000), --This is a note field for technical
staff
unnotes varchar(50), --The tech who posted the note
dtnotes smalldatetime --Now() function used to insert date of
when the note was posted
)

========================================

I'm still trying to go through the code to see if I can find the problem.
The Resolve & Approve button has not yet been codes and neither of the
queries for the reports. I deleted the code for the Resolve/Approve button
since it was my first error that I couldn't figure out so I was going to
just redo it. Then I saw the other errors, which also made no sense. How can
the text from a textbox not be there when a postback occurs??

Thanks for the help. I don't think I could move any further without it!

I think I found my problem although I couldn't narrow it down exactly.

Somehow, I was clearing the txtID.text textbox of its value just prior to
the SQL statement being executed, which was causing an error since I was
trying to insert a related record that didn't have a matching foreign key
for an exisiting primary key.

With some experimentation, I have resolved the problem (and created all new
ones too!).

Sorry for all the reading.
