Does anyone know how I can check to see if an image exists on another web host? I tried using the file system object but it didn't seem to work. I think my problem is that I have to check a URL instead of an actual file path to see if something exists there.

View Replies View RelatedWe have two tables EmpProfile and holidaysrequest tables.
EmpProfile has fields
EmpNo
Firstname
Lastname etc
HolidayRequests has fields
EmpNo
FromDate
ToDate
holiday requests table stores the dates employees have booked as holidays.
I want to write a query which will be used by ASP page to display everyone
who have not booked 29th - 31st Dec as days off.
I have built a page that lists all our databases, the
users connected to each database, and what application
they are using. Because these databases are moved, or
removed from time to time I need to check if the database
still exists before trying to query it. Otherwise I get
funny SID errors when it tries to process this command:-
Conn4.Open "Provider=OraOLEDB.Oracle;" & _
"Data Source=CD;" & _
"User Id=username;" & _
"Password=password"
Can this be done in ASP or should I be querying the error
collection or something?
I populate a recordset and dump it into an array. How can I check if a value exist in the array? I want to check if the c_Member_mgr has a particular value or not?
Dim rs2
set rs2 = Server.CreateObject("ADODB.Recordset")
rs2.open sub_Emp_Source, Conn
Dim aSubordinates
If not rs2.EOF then
aSubordinates = rs2.GetRows()
'Close Recordset to use the new array with the 2 columns data
rs2.Close()
set rs2 = Nothing
'Declare Constants for the above SQL columns for better readability
'Use these Constants instead of referring to the array numeric indexes
Const c_Member_Mgr = 0
Const c_Subordinate = 1
Const c_EmpID = 3
Const c_EmpName = 4
there is any way i can check if the database Exists. I mean from the code side. I dont want it to throw me any error thats the reason.

How can i check if a vlaue exists ? Sample to get the idea: Code:

View Replies View RelatedI have a web page that creates dynamical forms, depending of what kind of product it regards. When the user has chosen a product, data is collected from SQL Server and a form is created.
Some forms contains check boxes and some not. My questions is: How can I check if someone has UNCHECKED a check box? Because if that happens, I want to delete that entry from the database.
Since a form just posts the value of a check box if it is checked, this causes a dilemma.
Any ideas, I can't be the first one having this problem?
Just wondering if someone could look at this and see where I may be going wrong. The basic concept is to use FileSystemObject to see if an image exists. If it does, display the image. If not, display image does not exists message.
<%
Set fs=Server.CreateObject("Scripting.FileSystemObject")
strFilename = ="e:path oimageprodPixscienceTN" &
(RecordSet1.Fields.Item("ID").Value) & ".jpg"
If (fs.FileExists(strFilename))=true Then %>
<%=(Recordset1.Fields.Item("ID").Value)%>
<%
Else
Response.Write("No Image Available")
End If
set fs=nothing
%>

View Replies View RelatedI dont know if this is the right place to ask this but I have a database which contains shop details, each of which can have several images associated with it. In the database I am just storing the image paths, the actual images are held on a remote server.
I am able to grab the pathnames from the database and then use the following code to loop through the recordset displaying the associated image(s).
While NOT rs.EOF
Response.Write("<img src=""servernameImages" & rs.Fields(0) & """ width=""150"" height=""150"">")
rs.MoveNext
My question is, in the event of one of the images not being found, it just displays a red cross, is there any way of testing to see if the image exists before I try and display it?
i didnt know where to post this, but im using asp to process the data so here goes..
i want to allow users to provide a link to an image. this image location will be stored and calld upon in asp code. This i can do.
what i cant do is limit the dimensions of the image, is there any help available for such a thing in ASP?
(my thoughts)
when you right click an image and view properties from anyware it gives you the dimensions, is this what i need to get at and check?

View Replies View RelatedHow can I use ASP to check the size of the images used in my solution?
This is what I need to do:
If the width of an image is more than 256px, I want to set the image width to 256px. Images that is smaller (ex: 100px width) shall not be adjusted.
I have a couple of images that the user can upload, but I want to limit the size to 512kb(most of them will come from a digital cam).
Is there a way to check the file size before the page submits? ie a javascript function that i can call before submitting the page?
Is there any chance my server doesn't support global.asa files? (It supports ASP)
View Replies View RelatedI am using SQL server and ASP to create a webpage and display images directly from the database. My code is working fine, the issue I am having is when a photo is not in the database. For example, we have a table of homes and a table of photos. Not every home has a photo. So when I search the photo table for a photo that does not exist I want to display a "No Image Found" gif. Below is my code ....
homedetail.asp:
<img src='photo.asp?GID=" & objRS("GID") & "' width='320' height='240'>
photo.asp:
intGID = Request.QueryString("GID")
....
strSQL = "SELECT PHOTO FROM GIS_PHOTO_VIEW WHERE GID =" & intGID
....
intRecordCount = objRS.RecordCount
If intRecordCount = 0 Then
Response.Write "images/noimage.gif" <--- problem statement
Else
Response.ContentType = "image/jpg"
Response.BinaryWrite objRS("PHOTO")
End If
This works perfect when there is a photo in the database. But when the record count is 0, it passes the text "images/noimage.gif" back to homedetail.asp and homedetail displays nothing. How do I get it to pass the actual image "noimage.gif" back to homedetail.asp?
