Output Jpg Stored In Database As Long Binary To Asp: How?
For a while I am working with ThumbsPlus ( http://www.cerious.com/ ) as manager for pics.
The benefit of the program is that it stores all kind of information in a central Microsoft Database that easily can be manipulated. A thumbnail of the picture is also stored in de MDB as long binary (jpeg format)
I made a small script that extracts all kind of information of the MDB by use of queries and ASP. This works perfect for string/numerical information.
I am wondering if I can also write the stored (jpg)thumbnail to the asp file so that I have a preview of my picture.
Can this be done? What is the syntax?
I tried already :
Response.BinaryWrite BinData
Where BinData is the contents of the Thumbnail field. When I take a look at the MDB table in design view, the DataType of this field is "OLE object", if I open the table, the contents of the field displays "long binary data".

I'm attempting to read data written to a MySQL database and view it in the browser. I've searched the net for over 3 days and I've seen many posts that say it works great, but it's not working for me. The only thing that displays properly is a text file. Everything else is garbled. I desire to store & read PDF files though. Here's my code:
I'm trying to put a long hyperlink into my database table which works fine. I used longtext as the field type. My records insert just fine. But when I try to retrieve the records on the asp page all the other data shows up but the hyperlink data. Here's an example of my link.
I don't excactly know whether this is an ASP, webserver or SQL-Server problem:
I have an ASP with a search form. By clicking the submit button it redirects to my result.asp page which initiates a database query that takes pretty long (up to 4 minutes).
Now if I push the cancel button in my browser because it takes too long and want to open another ASP page in that browser window I just get the "page loading" bar until, it seems, the query I initiated before has finished, and then shows up the wished page.
What I think is, that the webserver is waiting for the the command:
set rs = db.Execute(sql_search_string)
to be finished by the SQL-server and does'nt respond to other page requests (but only in the same browser window) until the recordset is filled with the information from the SQL-server. Code:
Has anyone else found a memory leak using ADO streams to access binary data held in a database. I have searched through this forum and have not come across anyone else, so maybe it is just me.
The scenario is as follows: Windows 2000 SP3 MDAC 2.7 SP1 IIS5 MySQL 3.23 MyODBC 2.50
If I query the database and do a response.binarywrite everything works fine and no memory leak. eg. response.binarywrite myrecordset("blobfield")
If I read the very same BLOB field into a ADOstream I then get a memory leak in DLLHOST.EXE of how big that binary field was. ie If the picture is 140k in size DLLHOST.EXE increases its memory size by 140k.
This keeps on happening until DLLHOST.EXE is something like 250 MBytes in size at which point it stops working. Quick restart of the IIS Web service and I get all my memory back.
The command I am using to get the data into the ADOstream is picturestream.write myrecordset("blobfield")
I have also tried putting the binary data into a variable first before inserting it into the stream: set x=myrecordset("blobfield") picturestream.write x
The stream is closed and set to nothing at the end of processing. Everything is cleanly shut down. Through testing I know the memory leak occurs once the data has been written into the stream. The stream is correctly created as type binary.
The stream problem I am encountering does not seem to be limited to ASP, I tried it using Visual Basic to create a COM component to do the same job and still got a memory leak.
So the questions are: 1. Has anyone come across this before or fixed it? 2. Is there another way of getting binary data out of MySQL, something like the opposite of LoadFile?
I have wasted so much time on this problem but cannot find, having searched Microsoft's knowledge base and the rest of the web, any reference to the problem.
Assume that there's a website named www.abc.com. There are 2 ASP files & one MS-Access database file in this site. The 1st ASP file is named "SearchForm.asp" & the 2nd ASP file is named "SearchResult.asp". "SearchForm.asp" houses a Form with a select list & 2 TextBoxes. The select list is populated from a MS-Access database table.
When the Form is submitted, the user is taken to "SearchResult.asp" which retrieves & displays the records that match the criteria that the user selected in the select list & the text they entered in the 2 TextBoxes in "SearchForm.asp".
Now the records that "SearchResult.asp" retrieves & displays - I want to display these records in a ASP file named "ShowData.asp" which exists in another website named www.xyz.com.
Is there any way by which I can display the records generated by www.abc.com/SearchResult.asp in www.xyz.com/ShowData.asp....
I have included in my database a location (web URL) of a file that the person using my site can click on and it will work as a normal hyperlink and go to that page.
In case that doesn't make sense,
Say this is my database:
IMEtitle Sarah
LocationURL http://this.com/here.html
I want to display on my page Sarah and Sarah be hyperlinked. The hyperlink is pulled from the database as well as Sarah.
Everything appears fine, but when I click the link it says just adds it to the end, it looks something like this: http://www.nps.navy.mil/Content/DLR...S/Southwest.swf#
Whereas it should look like: http://www.nps.edu/DL/DLRC/media_de...S/Southwest.swf
I have done this sort of thing in PHP, but I am not sure how to do it in ASP.
I have a checkbox the value which goes to a database via a asp page that builds the sql string.
In the front end asp page, the checkbox code is written as follows:
<i><input type="checkbox" name="chk_Complete" value="<%Response.Write l_IsChecked%>"<%if cbool(l_IsChecked) then Response.Write " checked"%>>
The code to captures the checkbox value in the asp page that builds the sql string is follows
l_f_IsChecked = Request.Form("chk_Complete")
With this, when the database is already checked (and the checkbox shows checked) unchecking and saving makes the value of the checkbox value in database unchecked. At this point when the asp front-end page is refreshed it shows the checkbox in unchecked state(should be so). Now if I want to check the checkbox and save in the database, the checkbox value in the database does not get changed to checked.
strSQL="SELECT * FROM MyTable;" rsSet.Open strSQL, adoCon ...do some stuff... rsSet.Close adoCon.Close
Set rsSet=Nothing Set adoCon=Nothing
I have a couple queries stored in the database that I use when in MS Access. Can I call these queries instead of using a string to specify the SQL command?
The above seems kind of verbose for making use of a database. Can it be simplified at all?
When sending long emails a mysterious space-character is added after a certain number of characters. Any idea why that happens? I am using a Dundas Mailer control (if that matters) called from an asp script.
I have a database-driven site and it is possible for users to leave comments, which get written to the database. How do I make it so large comments can be added?I am getting this error message:
Microsoft JET Database Engine error'80040e21'
The field is too small to accept the amount of data you attempted to add. Try inserting or pasting less data.
/wall2.asp, line 37
I have set the default field type in the database to be 'memo'and set the default text field size to 255 (the maximum allowed)
Is anyone aware of any sort of asp coding to deal with long URLs? I have a few asp that pull URLs from fields within a MS db, which then display on a width-limited table. Is there any way to wrap these long URLs such that my table doesn't get widened? e.g. wrapping at "/" or something similar?
ok I have a page that displays all of the 3000+ records of people, phone numbers, and email addresses. on this page I have added a link that combines all of the e-mail addresses into one mailto: link so that we can mass notify these people of upcoming projects. the problem is that i think the link is too big for the browser to handle. the view source shows that everything is there but i cannot click the link. i have tried both IE and FireFox to no avail. The code is below just in case i have a typo or something...
sql = "Select * from people WHERE (IsNull(m_idstatus) OR m_idstatus <> 'id2') AND (m_email Like '%@%')" ...
y = 0 do while not rs.eof If (rs("m_email") = "" OR IsNull(rs("m_email"))) Then e_email = e_email Else e_email = e_email & rs("m_first_name") & " " & rs("m_last_name") & "(" & rs("m_email") & "); " y = y + 1 End If rs.movenext loop ...
I have also tried changing the format of the link by adding test@test.com before the ?bcc= but get the same results on both browsers. Like I said in the beginning I assume that the link is just too big for the browser; does anyone have any ideas besides making a mail form in the page? I would prefer to stick with a mailto link so that we can keep internal Outlook features.
I'm currently working on an ASP site that connects to a MySQL database I've built a form that allows users to insert press releases. They add the date and title and then the text of the release.
The problem that I'm having is that every so often when the user submits the form they get an error message saying "Command text too long" The record isn't added to the database after this
I use a longtext field for holding the main text of the press release Code:
I'm trying to use ServerXMLHTTP on an ASP (not ASP.NET) page to retrieve large binary data from a remote server. When the request is large (more than a few megabytes), the ServerXMLHTTP page jumps to nearly 100% CPU utilization for an unusually long time. The remote server needs a few seconds to prepare the request, during which time the CPU seems OK. It seems that as soon as the data is ready to retrieve, the CPU usage jumps and remains that way until the data has all been copied to the requesting server. That takes way too long - about 35 seconds when requesting a 12 MB file over a gigabit Ethernet.
I use ServerXMLHTTP hundreds of thousands of times daily on this same system on the same network, with absolutely no problem - but for smaller requests. There's something about the size of the request that makes it blow up.
I saw some reports of older systems with this problem (Windows 2000), but I'm running IIS 6 on Windows Server 2003, SP1.
I am trying to simply print to screen all the data in a colum from a .mdb file. Later I will do more advanced things but for now this would be good.
What I have WORKS, but takes a LONG time to retrieve the first record, if I tell it to retrieve more than one row it will time out. I was hoping to connect to the file directly and not have to create an ODBC connection. The code seems simple enough and the server is no dud (p4 2.4ghz) so do I need to setup a DSN and connect to it that way? Code:
I am trying to return a recordset of data. The problem is my SQL query does not fit on 1 row. What do I need to do to start a new row. I tested the asp when I trimmed my query down to 1 row and it worked.
I'm developing an intranet application using W2k server and IE5.5 - 6.x clients. I've got one particular function that calls a stored procedure to update a number of records, depending on user input. The problem we have run into is that this procedure can take a few minutes to complete in certain circumstances, and of course IIS times out.
I've been doing some searching for a solution, but most of the answers I've found relate to showing a 'Please wait' message while processing the page, which doesn't help in this situation. The others I've found relate to using MSMQ, which would probably help, but leads to a load of testing issues that I'm not prepared to deal with at the moment.
Are there any other 'common' ways to handle this at the ASP level?
I have a very long string statement that needs spltting down into smaller sections and segments. I know how to use the split() function, and it splits the string down into smaller sections, however when I try and split one of these smaller sections into segments it throws an error out. Firstly is it possible to keep splitting the same string again and again to break it down? If not does anybody know how I would go about breaking down the string?
I want to divide long HTML page (paging) into smaller pages.I know how to do it if I use recordset but in my project, I dont need to read from a Database, I'm reading a file system wich is a folder and list all files insid it.
I was performing some testing on my forms and in the comments section of the form, I copied and pasted a large amount of text. All of the text appeared on my confirmation page that I have that shows all of the submitted information. Once I hit submit on the confirm page so that the INSERT will occur, only about 1/4 of the text that was entered shows up on my "Submission Confirmation" page.
The text insert appears in the database, but only the 1/4 of the text that was entered. I'm using the "text" datatype and the length is set to 16. Can anyone think of why only a portion of my text is being displayed and then inserted into the table?
