im trying to let a user download a file from my website, for example a
picture. i dont want the user to have to right-click and do save-as, but
instead i want a window to popup (the window with "Save File","Open
File","More Info",etc) so that the user can download it easily. i have a
feeling this has something to do with headers, but i have no idea what the
correct headers are.
thanks in advance

OK, here's my 2p worth:

Q. Why am I getting the error message 'Headers already sent'?
A. PHP produces this error message when you try to set a header for a web
page after you have already started sending out the content of the page.
Web content is always delivered with a few headers at the top, ending with a
blank line. For example, a web page might start like this:

Some people have suggested the desire for code completion and refined
edit-time error detection are an indication of incompetence on the part of
the programmer who wants such features. Unfortunately these ad hominem
rhetorts are frequently introduced into purely technical discussions on the
feasibility of supporting such functionality in C++. That usually serves
to divert the discussion from the technical subject to a discussion of the...

I have a client solution that requires data and associated files to be
stored with data in a database. As such, I have a situation where JPEG
thumbnails/images that are stored as BLOBs (image data-type) in a SQL DB
need to be written to an ASP.NET page. The BLOB is actually wrapped by a
class written in C#, BlobObj, which can return a byte-array containing the
image-bytes. I can successfully write the image to the page using the...

Hi,
I am creating a solution with two projects. Basically, they share a
few common class files and forms. I finished one project, and it
compiles and runs fine. I just finished bringing in the second
project, and I get the following error on one of the forms when it is
invoked:

Hi everybody!
I'm using Visual Studio 2005 and don't know how to solve this problem. Till now, everything worked just fine, included all the necessary libs, headers and so on.
But there is the problem:
I have to implement a class ColorSpaces with static member functions, which manipulates a buffer from the class MSImage and returns it.
ColorSpaces.h looks like this:

Hi all,
I have an application which generates image graphs. These cache nicely
at the client, however if the user submits more data, I'd like to
force a reload of the image from the server.
I had a google, but all I could find were suggestions to use a varying
query in the URL. This is not a solution to my problem because if I
change the page to do that then ALL the graphs will be reloaded every
time.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
