The file is Base64 encoded and is being sent to the ASP code via a web service. Clear Response. SoapClient" oSoapClient. Binarywrite Base64Decode oAttachment.

End The BinaryWrite is adding extra null characters every other byte. Change it to response. I'm looking for a method to use the binarywrite without it adding the extra nulls. Is it a charset issue? Thanks BinaryWrite is doing the correct thing here. What is the return type for your Base64Decode function? Related ASP. NET Page to the browser. To properly send a filename I am adding a header: Response. I have tried with: Server. HtmlEncode but it didn't help. Do you have any idea how to solve this problem?

PK Put the file name in quotes:- Response. This is not the right way to escape a value for use in an HTTP structured header parameter. It only works in IE due to that browser's buggy handling, and even then not reliably. But the dirty truth of Content-Disposition is that there is no reliable, supported escaping scheme that can be used to put arbitrary characters such as ;, " or Unicode characters in the filename parameter. See this answer for some background.

Filename with special symbols e. Here is an article by a Chinese called chanext, he gave a perfect way to solve this problem: this article gave a sample code written with c to show how to get perfect solution to this problem in the all four popular browsers IE; Opera; Firefox and Chrome the filename "Microsoft.

Clear I have tried turning the PDF into an image and display, but received nothing in the image box.

ToBase64String bytes, 0, bytes. Length Image1. Note I didn't write the below code and I'm not a VB. NET programmer, so I can't guarantee it'll work. BinaryWrite bytes Response. Flush Then on our page, we use one of the techiques from the below link to embed the PDF, making sure to give the URL that points to our generic handler, and passing any parameters needed to generate the PDF via query string.

It appears it is only returning the "inner html". I can create an IE object and get the "outer html" but that is not too efficient since I have hundreds of search items. The webpage uses javascript to update the page once the html has been downloaded. This happens automatically in a browser. Below is sample code.

If the document size is greater than 4mb, I get an error "Response buffer limit exceeded". I did some research and tried different things. Only increasing the buffer limit in IIS resolved my issue.
