How To Send A Form With Binary Data To Another Server?
I'm trying to submit an image object, along with some other text fields to
another web server from within an ASP page but am stuck on getting the image
to be submitted with the form.
In a bit more detail:
1. When this particular page is executed, I want the server to pull an image
from a db (stored as a BLOB) along with a few other text fields. This part
is easy and I have no problems with it.
2. I want to submit the image, along with the text fields to a second
webserver which typically accepts its input from a form (ie, the second
webserver usually has a webpage where a user enters some information into
form and browse for a file. When clicking submit, the form fields along with
the file are submitted to the second server).
The reason for this is that I'm trying to migrate from one web based photo
album to another which uses a data structure that is complicated and
difficult to interface with, so I'm using the web based image upload
functionality of the new album. Code:

A website has a form with the first line as written below:
<form METHOD="POST" action="submission_form.asp" name="FrontPage_Form1" webbot-action="--WEBBOT-SELF--">
Can I, if I match the field names used, submit my form and have it sent to their server as if the submission had come from their server?
Could I use:
<form METHOD="POST" action="http://www.example.com/submission_form.asp" name="FrontPage_Form1" webbot-action="--WEBBOT-SELF--">
and I match all of the field names? Would that work?
Could I harm their "database", or whatever they are doing with the form submission?
Since you are going to ask "why". My reasons are noble enough. It would just make things much easier.

I'm trying to setup an ASP page to POST an image across to another page- essentially simulating what a browser does when you use <input type=file> in a HTML form.
I'm able to correctly setup the headers etc and do the POST, but I'm unable to include the binary data of the image.
The only way i've been able to do it is if I base64 encode the image. I'm using MSXML2.ServerXMLHTTP to do the POST, and I can't seem to do the .send with a form body that includes the binary data of the image. Code:

When we click the submit button as the following form, my understanding is it will submit the form to the web server, and then open page2.jsp. web server has some area to store the name-value pairs?? I just want to understand how it works internally.
<FORM ACTION="page2.jsp" METHOD="POST">
<INPUT TYPE="hidden" name="username" value="joe">
<INPUT TYPE="submit" value="submit form">
</FORM>
In page2.jsp
<%= request.getParameter("username") %> ....

I'm using ADODB.Stream to open a binary file on the server and write
it down to the browser using Response.BinaryWrite. It's working fine,
but i need to make some changes to the binary data before it is send
to the browser.
I'm trying to use REPLACE, but it's not finding a string that i know
it's in the binary file. Using InstrB i've found that the search
inside the binary data is being done in a Unicode format, but i don't
know how to make an ascii search&replace operation on binary data.

I am having the following error when submitting dynamic data to an SQL Server database:
String or binary data would be truncated. This is of course happening when longer datafields are being inserted. I've tried changing the data types in the database itself, but that does not solve the problem. Do I need to change the data type of the field before it is submitted to the database?

I have an asp page that uploads binary files. I am trying to pass the binary data to a function in a dll (written in c++) to process it. The file I'm testing with is the range of bytes from 0x00 to 0x51. When the data is passed to the function, it is passing it as the string "A^? ".
which is what is printed out when I do a Response.Write. How can I pass the binary data to the function? A Response.BinaryWrite prints out the correct contents of the file. Why won't it pass it as binary?

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.

I am working with IIS 5.0 and would like use the property CentralBinaryLoggingEnabled which if set true will create one single binary log file in place of a separate log file for multiple websites.
This property is available in IIS 6.0. I would like to know if there is a patch available for IIS 5.0 which will create this property in IIS 5.0.

I have a form that has the option to upload a file at the bottom. If you select a file it works fine but if you leave file selection blank the forms bombs. This is not how I want it to work. On the form you need to use ENCTYPE="multipart/form-data" in the form tag.
On the processing page I need to use Set to assign a variable to the form data. I tried using IF on the variable assigned to the file path but it bombs out telling me "This function is not supported". Is there any other way I can check to see if curQes has a value assigned to it?
