Is there a way I can test if an image file exists before displaying it?
I have a database that has an image field in it that users enter a filename into. Is there a way for me to check using an "if" statement that the file is actually on the drive before displaying it? ie:
<%okimage=(rsFile.Fields.Item("image").Value)
If okimage='actually on the drive' then%>
<img src='(rsFile.Fields.Item("image").Value)'>
<%else%>
<img src='noimage.jpg'>
<%end if%>
Does anyone know how I can detect if a image is missing from the server before the browser tries to render it, I guess this would have to be done via some sort of preloader, the problem being I am the site in question has around 30,000 images and keeping on top of missing images is a impossiblility.
View Replies View RelatedI first noticed this in my own app. Images would show up missing [red X] randomly on IE 6.0.2800.1106 on Windows 2000 server.
I then was able to repro this problem on Microsoft's website!!! The page I used was
http://www.microsoft.com/windows/ie...sp1/default.asp
After pressing [F5] to refresh the page six times, I noticed missing images on the page.
This problem seems to be very reproducible. I coded a sample ASP page which references the same images 10 times on the same page. Loaded in IE. Upon pressing [F5] several times, the images will be identified as missing [red X]. Refresh the page again, it's fine.....etc.
I'm up-todate with all latest MS patches. Has anyone else seen this problem?

Its very common to pass information from one page to another using asp through the address bar. It is also possible to hack the code if one notices this. I.e the price of the item.
I was hopping someone new a way which would either mask the address bar so it never changed from example it stayed static irrespective of the page the view is on. Or they must be another way.

View Replies View RelatedIs there a way to tell my data table that lists my records
that if a record's entry contains "Is Down" to show it on the page but if it contains "Is Up" to hide it?
I have a site, constructed with dreamweaver, that contains a master-detail page set.
I have make some changes to the code (although I 'm not a programmer, I am beginner), so that I can insert records that will
be displayed when the date of the record is equal to the current date(server's date).
The detail page is something like http://localhost/1.asp?id=495
My problem: I discovered that anyone that hits to the browser any other id number by hand(example
http://localhost/1.asp?id=496), can view the records I wanted to be displayed when the appropriate date come!
So, I have not any way to protect my records from these people?
What can I do, so that nobody can see the future's records above the current date?
The master page already has a 'where' statement, and displays only the records with date=< current date.
My problem is at the detail page.
Suppose someone hit in the browser, just because he wants to cheat me, write another id in address bar, replacing the one the browser currently displays.
Thenhe has discover a brand new page which should be online in the future.
That's my problem.
It would be nice if I could hide the real address from browser address bar.
Or if I could somehow change it in order not to reveal the real address and this could make it more difficult for someone to reveal future's pages.
I know the use of frames hides such information(exact address) but as far as I know this solution has many disadvantages.

View Replies View RelatedI have created a drop down box that picks items (active product lines) from my dbase (sql), once the user selects an item from the drop down, I would like asp to relate that choice to the next table and pop up another drop down box (active products from the above product line chosen).
I'm assuming that there needs to be some function to hide the second drop down box until the first choice is made (I could be wrong here??) so I don't know what the code would be for the page to stop showing anymore information until a choice is made. I usually show code here but this is really a question about code that I don't know.
I have added a new field in my database for the news items, basically a boolean value (true or false) for the display or hide of a news article. I have simple added to my queries WHERE newsDisplay, and that does the job except now I have one query qhich is actually causing me a small problem, due to the query already having a where clause.
like below:
dbSelectQuery("SELECT * FROM tblNews WHERE newsID ORDER BY newsDate DESC")
So that leaves me a little puzzled as to going about this query which should solve the small issue, I was even thinking is there a way I can use an if operator. Something along the lines of if newsDisplay = true or checked then do something else. Someone must know. I just dont think you can actually use an if statement on a sql query? Any tips would be perfect . PS - The new field I have added is newsDisplay as a yes/no in an access database.
