Hi. I come here with an issue: how to launch a form from a local HDD, after an online model:
I have a original model:
<form name="uf" method="POST" action="/WSD4RRR/somefile.do" enctype="multipart/form-data">
<div style="background-color: #c6c6c6; padding: 5px">
<span>Choose file:</span> <span> <input type="file" name="linkdoc" size="75" value=""></span><span><input type="submit" value="Send"></span>
</div>
<p style="color: red;">
</form></td>
my (critical) task is to programmatically put a file without using CFileDialog, and to programmatically click "Send" button.
I create a clone of this html file, on my local HDD, just like this:
<form name="uf" method="POST" action="https://original.site.com/WSD4RRR/somefile.do" enctype="multipart/form-data">
<div style="background-color: #c6c6c6; padding: 5px">
<span>Choose file:</span> <span> <input type="text" name="linkdoc"></span><span><input type="submit" value="Send"></span>
</div>
<p style="color: red;">
</p>
</form>
I only replaced
input type="file" with
input type="text"
and, most important, action ... but when I click "Send", I get a response from server: You are not choosen any file" ... which is right, because on my file, on "action" tag I put the original file path ... do you know what I mean ?
I put all these into a VC++ app, where I used CHtmlView for handling all this ... but I am stuck here ... and I don't see any output ... it is mean a lot for me to solve this ... Can you give me a little help ?
Thank you.

You can't automatically upload files from the client machine. Would you want a website automatically uploading your files? I suspect not, so you can't do it to others.
If you want to automate this you'll need to do it my programatically constructing the appropriate html request to the server via your VC++ app, you won't be able to get a browser component to do this for you.

Ok. This is the scenario: I have a html page, with a input type file element (included in a form), let say page 1. If I manually choose a file from local HDD, and I submit that form, the server respond me with some values, listed on another html page, in my browser, let say page 2.
So, if I send to the server a VC++ request with all data inside, somehow in page 1, and I don't use the browser for that, how can get the expected data from server (expected page 2), inside of my (program) browser ? Because I need to collect that data (from page 2).

Depends how much you want to show. You could just extract the relevant data from the response and show that somehow, even in a browser if it allows you to show specific html rather than just load from files\urls. If you wanted to show the whole page you could convert any non-absolution resources to absolute ones, so
src="/css/styles.css"
would become
src="http://www.targetserverhere.com/css/styles.css"
and that would give you html you could possibly load into your browser control.

I don't know VC but that looks like for uploading a file to an ftp server, not for POSTing a file to an http target.
|
|
|
|
|
|
Yes that looks more like it.

The code is probably just ignoring the response, but it should be possible to get the response with the same call. Maybe google for other examples using the same class (not necessarily to post a file, the code for getting the response should be the same regardless of what your request was)

I've tried, seem to work  Thank you !!!

I am learning CSS so dont shoot me with bad attitude.
In this code I am learning how to use sprite in CSS.
<!DOCTYPE html>
<html>
<head>
<title>CSS</title>
<style>
body {background-color: powderblue;}
#img1{
background: url("testCSS.png") 0px 0px;
background-repeat: no-repeat;
width: 60; height: 30px;
background-size: 100px 50px;
}
#img2{
position: absolute;
width: 25px; height: 25px;
left: 50px; top: 50px;
background: url("testCSS.png") -0px -25px;
background-size: 100px 50px;
}
#img3{
position: absolute;
width: 25px; height: 25px;
left: 100px; top: 100px;
background-image: url("testCSS.png") ;
background-size: 100px 50px;
background-position: 75px 25px;
}
.square{
position: absolute;
width: 30px; height: 30px; ;
left: 150px; top: 150px;
Background-color: #FF0000;
}
</style>
</head>
<body>
<img id="img1" src="test.png" > hi1</img>
<img id="img2" src="test.png" > hi2</img>
<img id="img3" src="test.png" > hi3</img>
<div class="square">box</div>
</body>
</html>
I have a real problem to resolve, that's why I have to learn this CSS ?language?helper?
I have 1350 images to load into a single plain html page. The images, i made them as small as I could 150x120; barely to distinguish the message. And is taking 20 seconds until the page is finished loading. At higher resolution per image, higher load time!
I want the page to load close to instant.
It's not for a public website, its a local file only for me.
And I google-find that there are some ways to shorten load time.
The best one that suit my case are the sprites. I read about them all day. And this code is my practice on this thing. But I am worried about it. Probably i am so new to this thing.
This code here; every img# instance i have here, is loading !A NEW! png image?
If it does, it is loading a ton of images and it beats the purpose of using sprites.
I want to load one time the sprite image(in a string variable) and reference it in CSS code.
Again, i am new to this thing. Please make some sense for me.
Thank you!
#img1{
background: url("testCSS.png") 0px 0px;
}
#img2{
background: url("testCSS.png") -0px -25px;
}
#img3{
background-image: url("testCSS.png") ;
}

This isn't really a CSS problem, but rather a latency/synchronous call one.
Here's the deal: your CSS operates in a synchronous manner, which means that it makes one request, receives a response, then makes the next, and so on. In your case it's doing that at least 1350 times. It's never ever going to be instant with your current design.
Now, I'm assuming that the user (you in this case) are not viewing/consuming 1350 image files at once, so there's a workaround called AJAX. You pull down the images that you need instantly, and have a JavaScript running that will pull down images as you scroll.
One jQuery library that does this is GitHub - webcreate/infinite-ajax-scroll: Turn your existing pagination into infinite scrolling pages with ease

very cool response! - thank you mister Nathan Minier.
(Intuitively) I was afraid of this part actually. This sucks.
I was thinking to make multiple pages with fewer number of images to load (as my backup plan).
Your plan to load as I scroll, ugh, it's hard (for me as a beginner into html helper languages).
Is a good idea - dont take me wrong. It's not impossible, but hard for me at my level.
Another idea is to use variable in javascript... i have no idea if it will work. I'm thinking on variants. I will have to test/try. But is faster to ask. If you have other alternatives (to load faster) put your answer here please.
Thank you!

Another option: if you don't have an actual need for the images to be individual, make sheets, each of which has a lot of images. Now, each call will load hundreds of images at a time, depending upon how many you put on a sheet -
Then - if you need individual image access, have the option to load images from a single sheet as individual when (something, like a button) on that sheet is clicked.
You may even be able to put larger images on the image-sheets (first paragraph) for better visibility.

You are using tunnel vision (i.e., fixed on a single idea) with the sprites.
Open your favorite image editor.
Create a blank page.
Paste a lot of your little images on it
Save it as a single image (jpg, for example (smaller than png))
Now a single image will allow your users to view many images.
Something you've seen before, like this: https://assets.awwwards.com/awards/external/2017/07/59689b0d0ea87.jpg[^]

Greetings experts,
I am not sure if this question fits into this forum but please let me know if not.
We have a domain name, let's call it serverA.
This server hosts our website.
This website is hosted internally.
Currently, employees view this site by typing the following on address bar:
http://serverA/departments/
We would like to mask this domain URL so that employees can type:
http://public/departments/
and the website will display same content it was displaying under http://serverA/departments/
We have asked our infrastructure team to handle this by using forwarding under DNS but they tell us this is not possible.
Is this true that it is not possible?
If this is not possible as they say, any ideas how we can handle this?
This is a WordPress site hosted in IIS.
Thanks in advance.

If you're looking at bare machine names (no "." in the name), then you'll need a new "A" or "CNAME" record on your internal DNS server pointing to your web server.
If it's public domains, then you'll need to control the domain you want to use. Again, you'll need an "A" or "CNAME" record on your public DNS server pointing to your web server.
It should be fairly straightforward to set up, so it sounds like there's been some miscommunication somewhere along the line.

new to php and trying to understand the use of and management of sessions
assumptions are: The entire site would be https and users would have to login to do anything and clicking on a saved link would realise the user wasn't logged in and auto redirect to the login page
session seems to be the appropriate? way to control whether logged in or not by doing session_start() at the beginning of each page and then looking at the variables that are set by the login page
my searching and reading suggests that sessions can be copied/hijacked and used to access pages as a user and certainly closing the page and then re-opening doesn't crash the session although closing the browser does
question 1. providing my logout function clears the session using array() and then destroys it, is there any other reason/time for me to use session_regenerate_id() ?
question 2. if hijacking/copying is possible how does a regular (timed?) obliterate, destroy, regenerate help this in any way? because it seems to me that my target page wouldn't be able to tell the difference between a copy and a valid new session
question 3. is there anything else I need to do for good practice

Hi, I have a web API method and it returns IEnumerable<cases>. Cases is a wrapper class of "Proc" Class. I am consuming this web API from my client. If Proc has count 0, I can able to get data in my client from Web API. When Proc has value (greater than count 0), I get error "Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host". I am working in VS 2017 and .Net Core 2.1 Please advise
Cases.cs
public partial class Cases
{
public CaseDetails()
{
CaseProcedures = new HashSet();
}
public int Id { get; set; }
public int UniqueNumber { get; set; }
public HashSet Proc { get; set; }
}
Proc.cs
public partial class Proc
{
public int Id { get; set; }
public int CasesId { get; set; }
}

Yeah, you do know that a 401 code is an authorization failure, I trust.
The W3C is your friend! The HTTP 1.1 status codes apply to 1.2 as well.
