POSTing A Binary File Using Multipart/form-data
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:

Is it possible if i wanna append xml data and upload picture at a same time using the same form?
The problem i'm facing now is, when i add the 'multipart/form-data', i can't append the xml data
I know there's one solution, using 2 FORM but the project i'm doing now is designed to be put them both (file type for upload and textarea for append) together
Besides, i have no idea how to encode or decode the posted data.

I have a form which uses the encode type "multipart/form-data". How do you parse and iterate through the form field collection once the binary read method is used?

If I'm using multipart/form-data as the enctype and the action is the same page how do I check if the form has been submitted? Usually I'd use something like this:
Code:
if request.form("input_submit") = "Save" then
' Process the form ...
end if

I am using VB 6 and ASP to upload files to the web server in one of my web applications. The architecture is something like this...Thin ASP/html front end using multipart/form-data when user selects the file and clicks on upload a COM object is being called to upload file.
This works absolutely fine when dealing with file sizes in b/w 1 to 15mb....Now users are trying to upload huge file sizes such as 80mb/100mb. the web application dies without uploading the file....hence was interested to know if there is any size restriction for this???
The COM object is written using ASP Scripting library, MTS scripting engine, ASPSOFT upload....references.

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?

I am near to desperation as I have a million things to get a solution
for my problem. I have to post a multipart message to a url that
consists of a xml file and an binary file (pdf). Seperately the
posting words fine but when I want to create one multipart message
with both then things go wrong.
The binary file is converted and of datatype byte()
The xml file is just a string.
I don't know how to merge these two into the multipart message. I have
tried converting the binary to string and then concatenate but that
doesn't work as it seems to leave off the last part of the file and
the boundary.

I am running IIS5, Win2k Server, and .Net Framework 1.1.
For some reason asp forms will not post data. So I have
a form with a text box. The form's method is set to post
and I have a submit button.
The weird thing is that the page works fine without using
SSL and/or the FQDN for the server. Code:

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:

I am trying to complete a file upload form and I am getting very close (at least I think I am). Part of my process is that I want to display the file location back to the user after the file is uploaded.
So here is what occurs.
-I have a from that has the encType="multipart/form-data" as part of the form (it is doing a post). -In the next ASP page, I try to view the contents of the INPUT TYPE=File by using Request.Form("txtFileLocation"). The problem is that when I display this value it is blank.
This is part of a file upload process so I think I have to use encType="multipart/form-data", correct? Then assuming I have to use the encryption or assuming it is wise to, how can I retrieve the path the user entered in the previous form in the txtFileLocation?
I tried this without encType="multipart/form-data" and then I was able to display the path entered but the way I understand this is that it is required for the file upload process or at least it adds security.

I have a basic file upload form.
<br><br>
<FORM METHOD="post" ACTION="uploadaction.asp" enctype="multipart/form-data">
<table>
<tr><td><b>Image</b></td><td><input type="file" name="UploadFile"></td></tr>
<tr><td colspan=2 align="center"><input type="submit" name="upload" value="Upload"></td></tr>
</table>
</form>
what exactly does the enctype="multipart/form-data" do? I'm having trouble getting the request.form("UploadFile") to work with it, but it has to be in the form for the file upload to work. Is there a way to "undo" this once it makes it to the action page?

i have created a registration page containing a form than sends username password to an asp processing page. If the user exists it sends the user back to the registration page with server.transfer command otherwise it adds the new user to the database as expected.
Anyhow I now want to add an upload feature to the registration page (using pure-asp). The example I used says that the form Enctype property should be set to mulipart/form-data.
Now when I add a new user via the registration form, the processing page for some reason assumes the user is already registered (BUT IS NOT IN DATABASE) and the server.transfer code is executed ? sending the user back to the registration page.

An application is logging faxes sent in SQL2000 image column type. I have
found code on the net but what it is doing is prompting to save to local
which is fine for single page image. Not good for multiple page faxes. I
have not been able to locate an example to load in the browser or how to
handle multiple image in the one column. Code:

I'm working on a shopping cart that uses PayPal when the user submits their information 3 things need to happen on the same page:
1. User information gets saved in a database
2. An e-mail is sent out
3. Variables are transferred via a "POST" method to the PayPal API
I've successfully made it through the first 2 but the 3rd one is killing me. How do I do this? The only way I can think to do this is with the response.redirect but it can't be a GET it needs be a POST. Any thoughts?

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?

An insert page and an update page will not let checkbox data be posted to the database. I am using Dreamweaver for all code with no tweaking on my part. If i remove all checkboxes from page i can post from both pages.
I've made sure that there is no data type mismatch. I do have another DB table which i can post to without incident. It seems i have exhausted my ability to solve this one.

I've created a form that posts data to a script and the script checks the values. If the values are invalid, I want to be able to "post" the data back to the original page for them to be picked up. Is this possible?
I can't use JavaScript for client-side validation as the data to be compared against is in a database. I don't want to use session variables as they are server intensive and can expire. And I can't send the variables through the URL as some of the fields are textareas and could hold long values...
