Response.BinaryWrite For One JPEG Is Very Slow
I am using Response.BinaryWrite to display JPEG's to the browser. The
problem is that in IE, one particular JPEG is loading very slow. Normal
JPEG's take a few seconds, but this one sometimes takes up to 30 seconds.
THe weird thing is that if I refresh really quick, the JPEG appears for quick
second, and then the new Response.BinaryWrite kicks in. So, it looks like
the browser has the image, but for some reason it is not finishing loading it
into the browser. Code:

I have a problem when trying to do response.binarywrite for files > 64kb. I am reading a blob data from the database, this blob data contains files. To read from database ADODB.Recordset is used. I am using the following code to write on to the browser:
Response.ContentType="application/vnd.ms-excel"
Response.BinaryWrite rs.fields(blob field)
This works fine when the blob data is < 64 kb but when this limit exceeds then an error is thrown. how I can go about and read files > 64 kb ? Is there a maximum limit on the size of the file that can be used with response.binarywrite?

when I upload images to a db, everything seems to work smoothly. But when I'm trying to view the page, it seems that there is sth wrong with images - all of them are cut at the bottom. The image size is correct, the filesize is ok, but the bottom part of the image is blank...

I made a posting a while ago regarding doing a binarywrite of a large
file in chunks and got a lot of helpful responses. I was able to make
it work then. Unfortunately when the project is being tested its not
working and I am getting some weird results when testing. A month ago I
was able to stream a file of size 80Mb and it worked like a dream
Yesterday it would not work on the same file, but would stream smaller
files. The largest file i was able to stream yesterday was 55.5MB.
Today it wouldnot work with the 55.5MB file but only with a file of max
size of around 54.5MB. I can't seem to figure out what is causing this.
Because the code is the same. I actually get no error, with the file
size i mentioned i get a popup window within seconds for the file
download. But anything greater than that file size (max size as of
today 54.5) even if it is an MB more i get a blank screen but it never
pop ups the file download box Code:

Anyone know what might cause my ASP to start running slow? It's been running fine until today. Today when I pull a repost, it takes forever to for the code to create the page.
When I go into the Access database itself and run the individual queries, they run just fine. It only takes a fraction of a second for the data to apprear. When I run the ASP code to see it on the webpage,it takes around 30 seconds!
Anyone got any recommandations on what I need to check? It just doesn't make any sense that all the sudden it runs flat out SLOW.

On my WinXP machine, with both IE6 and Firefox 1.0, response.redirect and server.transfer take about a minute. But on my WinNT machine with IE5.5, it works instantly. What's going on?

rtf files cause so many troubles,i.e.,allow the users to download the files, slow loading,incompatible with other browser, and so on. Do you think I should convert them to JPEG files to embeb them into HTML?
Once converting JPEG,it is easier to programming in HTML(i.e.,just add the image tag),load faster,and prevent the user from download the files?

I have a JPG file residing on my server with an ASP file. I wish to call the ASP file and have it return the JPG file. I do not want to load the JPG into some kind of ASP Image Processing Object. I just want to return the file.
I have already identified the content type with Response.ContentType = "image/JPEG" but can't get away from this text-only read/write system.
I haven't programmed ASP in years and have since moved onto PHP, so I am having trouble doing some of the basics

Im currently making a photo album website which has an ASP page to look in an images folder for any available jpg images.
What I would like is to extract the jpeg data such as width, height, title, bit-depth, comments etc.
All the fields can be found in windows xp if you right-click the image and then click Properties. Select the "Summary" tab and there is where all the jpeginformation is stored and can be edited.

help me regarding the 'Response.BinaryWrite' I am making one web application where I need to store some of client logo's and others images. In this context I am able to store images into .DB file and even able to display into browser to. But it seems to be 'Response.BinaryWrite' does not support 'html/text' hearder if you user 'BinaryWrite'? I had tried many way to do so but its does not write binary if pages content <html><body> tag's.
I could had done it by uploading images into disk, which is quite simple method and faster too<img src"images/<%=filename%>.jpg/gif"> by having unique file name. But I am not the person who is going to monitor it as user itself has a persmission through the web to have there image as they want to give file name etc. Also I can't have individual directory for each users as if tomorrow users grow then what I suppose to do?

I am using Response.BinaryWrite to write a PDF to the browser. Everything works great on IE and Safari but when I try to use Firefox the browser hangs. The title bar says application/pdf but nothing ever shows up. Going directly to the pdf works fine but unfortunately am unable to do that in the long run and must use BinaryWrite.

I have a commercial database written in access and I'm trying to display some images, jpegs, stored in the DB on web page. My code is as follows:
Response.ContentType = "image/jpeg"
sql = "SELECT PartImage FROM Parts WHERE ShortID='AAPTM01'"
Set rs = AMConn.execute(sql)
If not rs.eof Then
PicSize = rs("PartImage").ActualSize
if PicSize > 0 then
Response.BinaryWrite
rs("PartImage").GetChunk(rs("PartImage").ActualSize)
end if
End If
set rs = nothing
All i get on the page is the image not found icon with the red cross in IE.
What could possibly be going on?

Been struggling over this issue for a long while. We store PDF's in our SQL Server database. And I do a BinaryWrite to display the PDF.
It works for me without issue, on FireFox, IE, and Opera! But we are receiving feedback that some users are receiving the file does not begin with %PDF message ....

I'm having some problems with the Reponse.BinaryWrite, IE 6.0 and Adobe Reader 6.0. When I try to write a pdf-file to an IE browser with a Adobe Reader 6.0 installed then it just displays a blank page and the earth on the top rigth corner keeps turning like it haven't read the pdf-file (for 10+ minutes on a lan).
If I change the settings on the Adobe Reader 6.0 to not open in a browser, then it works fine. If I use Mozilla 1.4 then it opens fine as well.It works fine as well with Adobe Reader 5.1. The code looks like this:
[Some code that places the pdf-file in a byte array called vntStream]
Response.Clear
Response.ContentType = "Application/pdf"
Response.BinaryWrite = vntStream
Response.end
I have tried to place a Response.Flush after the BinaryWrite, but it just makes the Adobe plug-in say something like "document corupted".

I`m writing a little routine that captures the data from a form submit (ie a picture) and then at the back end the asp will saved it back out into a file on the server.
I can capture the file fine and display the binary data to the screen.. but now I`m trying to write the data back into a file on the server. After a bit of searching around on the net I found that most people where suggesting using the ADODB.Stream functions.
So this is what I've got but for some reason when I go to write the binary variable it complains. Code:

It involves using ASP/VbScript and ADODB.Stream to read binary data from a *.DOC or *.RTF
file and then send it to the user with Response.ContentType and BinaryWrite.
Everything works fine until I try to Replace() certain strings in the *.RTF
file with my own data. I'm assuming Replace() is choking on the binary characters, or
incorrectly thinking 0x00 values are marking end of string. Code:

I am doing a binaryWrite to allow users to download files. The problem
occurs if the file is too big. Some of the files i have are close to
100 megs. I read on msdn that if the data is greater than 4MB it is
advisable to break it up into multiple chunks Code:

I'm working on a site that is just *extremely slow* on certain pages that are very database intensive. Now... I've worked quite a bit with databases before - and this is different. It's ridiculously slow.
I've looked through the long ASP script (it's a calendar listings page, with some more db stuff under the calendar).
There's not really anything else I can do to fix up the code. I've consolodated SQL statements, converted everything to GetRows... closed my objects immediately... etc. I've also added indexes to the db fields in my WHERE clause of SQL.
The page isn't *that* complicated that it should take so long. Sometime it even time-outs.
I've tried so much, and nothing is working.
Could it be that I need a dedicated server? Something I'm missing in the code? (It's really long so I'd prefer not to post it if possible but I might).
