I have an IP camera that feeds video over lan or the internet thru a browser. It has its own interface on either Mozilla, IE or other browsers. I tried calling the site using the Microsoft Internet Controls component and it works fine. The GUI is called upon and I see the feed along with the buttons. My problem is that I want to use several Web Browser controls and divide the page to show only the camera feed. I also want to separate the arrow keys present to control the camera. Basically, instead of one complete browser window, I want to divide it into several. Is this possible? Thanks in advance.

I'm using VB6 by the way and the code I used to call its interface is

WebBrowser1.Navigate ("http://192.168.0.5")

Firstly, the IP needs to be where the camera is uploading, which it seems is fine.

Yes you can use multiple web browsers on the same form. Use say, command buttons to load the required browser.

What exactly is your problem though?

It works as a browser and shows me the GUI of the camera control. I want to divide the said GUI into several browsers. Here is an image that can sort of explain it.

What exactly does the GUI of the camera control consist of that you need to break down? Is it one application (camera's) that you want to split say the video control from the control buttons?

I understand the diagram above, why not just add a second webbrowser. What does the second browser need to contain?

You are right. I want to split the video feed from the control buttons. The first browser has to contain the feed.

I do not know the signals that are being sent to the camera to control it. So I cannot sent bits out over the UTP cable to control the camera. Rather, I want to make it look like my own interface. My plan is to make new buttons over those existing ones.

There may be no need for a second browser if possible. All I want is to have four command buttons that when clicked, will click the navigation keys in the browser as well.

That explains it more.:)

Whilst in the browser, right click on the browser and select "Source Code" from the pop up menu.

Search for the control names, say cmdNext etc. Once you have this, you can manipulate the controls by say setting them to not visible etc.

It will go something like -

MyBrowserNameHere.Document.All("TheControlNameHere").Click

MyBrowserNameHere.Document.All("TheControlNameHere").Visible = False

That explains it more.:)

You can use Google Chrome, right click on the control, then click the Inspect element. It will be easy for you to view the source from there.

@Andre,
I tried something like

WebBrowser1.Document.All(right_up.gif).Click
WebBrowser1.Document.All(right_up.gif).Visible = False

but an error arises saying an object is required

@jhai,
Thanks but the source code is more or less the same in any browser.

@topic,
To make things clearer, I guess it is better to provide a concrete screenshot. Attached is the actual camera GUI. The camera is a FOSCAM FI8908W

Viewing the source, here is part of the html code that might help.
<img src="videostream.cgi"> - This is the video feed. The exact site is 192.168.0.5/videostream.cgi

If I go to that site directly thru the browser or thru the VB control, the video feed does not load. I guess it is because authentication is required before you can access the GUI.

<img src="images/up_up.gif" onmousedown="up_onmousedown()" onmouseup="up_onmouseup()">

<img src="images/left_up.gif" onmousedown="left_onmousedown()" onmouseup="left_onmouseup()">

<img src="images/right_up.gif" onmousedown="right_onmousedown()" onmouseup="right_onmouseup()">

<img src="images/down_up.gif" onmousedown="down_onmousedown()" onmouseup="down_onmouseup()">

These are the source codes of the navigation keys. Only the up, down, left and right. These are the more important ones. Hope these additional information is of any help.

I always use Google Chrome in web creating scrapper.

If possible, how about providing the website address so we can analyze the site ourself?...

Unfortunately the camera has problems with the UPnP which makes it hard to control over the internet. We are planning on using this over LAN only. Any suggestions on how to divide the browser interface? Or possibly utilize the codes in HTML to call the camera functions? Let me know if you want the entire source code or if the ones earlier posted would suffice.

Sorry, been away for a while.

You are getting an error because you have put a reference to an object and not a control -

WebBrowser1.Document.All(right_up.gif).Click
WebBrowser1.Document.All(right_up.gif).Visible = False

right_up.gif is a picture object. You need to get the name of the control that holds the picture, maybe a picture box etc.

That's alright. I don't know what sort of control it is since the interface given is from the browser and not a standalone application.

I found some interesting codes when I inspected with Opera. I think there might be a way to make my own interface with the use of these functions and scripts but I don't know how to call them in VB6.

From what I could gather, the following is controls -

action_zone.location is the picture box where the camera pictures is shown,

if (image_reversal.checked)
		flip|=1;
	else
		flip&=2;
	if (image_mirror.checked)
		flip|=2;
	else

is check boxes

decoder_control is the control to handle the flip etc of the picture,

and so on... With the code I gave earlier on, you can now manipulate these controls.

Hi, I tried all these codes but all gave me different errors.

WebBrowser1.Document.All(plus_up).Visible = False

Object doesn't support this property or method

WebBrowser1.Document.parentWindow.execScript "leftup_onmouseup()"

Could not complete the operation due to error 80020101

WebBrowser1.Document.getElementById("plus_up").Click

Object variable or With block variable not set

Thank you for the link. Unfortunately, none seem to be effective. Its pretty much due to the complexity of the hardware I am trying to control. No worries.
