hi,
sir i am a student of final year(3 rd)polytechnic in information technology from the vidt\ya bhawan pollytechnic college udaipur rajasthan .
i want make a software as a "webcam security" so i want to know i shuld choose which of the platreform.

This is a rather difficult question to answer, since you have given no indication of what language you will be using to develop in, or what level of experience you have. I would suggest you go to the articles page and search for webcam programs as a starting point and proceed from there. But please remember not to submit any of the CodeProject articles as your own work.
I must get a clever new signature for 2011.

i want to ask that how to place an exe in windows 7 startup so that the user (user with USER RIGHTS- LIMITED ACCOUNT ) can't remove that exe from windows startup only the administrator can remove that exe.
If i place in "startup" folder than user can easily remove it

It's ok to have it in the startup folder, you just have to set the access rights on the file accordingly.
Rightclick on the file and press properties, then select the security tab and remove all rights except read and execute for the user/user group.

Depending on the tasks to be performed by your application, a Windows Service could actually be the right way to go.

Hello all,
I'd like to know how do you cope with this situation:
* Two network groups.
* Some computers in the first group and some computers in the second group.
* No DHCP enabled in any of the groups.
* One ADSL (no wifi) that must work in both groups (192.168.0.1).
* 192.168.0.xxx is the address range in both groups.
The first group has to be able to remote connect (remote access) to computers of the first group.
The second group has to be able to remote connect (remote access) to computers of the second group.
A) Does this mean that I can have only 255 computers in a network?
B) Without a hardware solution, can I have a set of software settings that would allow me to achieve the previous?
Could you give me some pointers/recomendations? and please avoid this: http://xkcd.com/138/[^]
Thank you in advance...

A) Actually you have a maximum of 252 computers in the network if you're connected to the internet.
0 is the network address and 255 is the broadcast address, and then your router needs one address.
But I think we need a bit more information on what's defining these two groups. As the're supposed to share the ADSL connection it's not a geographical grouping.
So my guess is that you're having two companies that needs to be kept apart while sharing the infrastructure.
Have a look at VLAN[^]. While normally being a hardware solution, there are also software to do the job. I don't know what security implications you can expect though.

No. This range, when coupled with the default subnet mask 255.255.255.0, gives you 254 addresses. But there's no reason you have to use that subnet mask.
Given an address for your network of 192.168.0.0 and a subnet mask of 255.255.254.0 you have 510 addresses available - that is 192.168.0.1 through 192.168.1.254. Visually (if I can render this):
11000000.10101000.00000000.00000000 IP Address = 192.168.0.0
11111111.11111111.11111110.00000000 Subnet Mask = 255.255.254.0
ANDing gives the network address:
11000000.10101000.00000000.00000000 (192.168.0.0)
Hosts can be addressed from
11000000.10101000.00000000.00000001 (192.168.0.1) to
11000000.10101000.00000001.11111110 (192.168.1.254).
The bits to the right of the least significant 1 in the subnet mask are available to be assigned to hosts on the subnet, while the space marked by 1s identifies the network. If you need more, you can always change the mask to 255.255.252.0 or 255.255.248.0, etc. Each step will double the available host addresses.
Members of a workgroup can access other hosts within the same network, and the subnet mask defines what digits in the IP address should be interpreted as the network identifier, and which are host identifiers. If your users need access to the Internet, include a router in your system with a LAN address within the network you've selected, and set the Gateway for each host that requires access to match the router's LAN address.
By the way, not using DHCP will cause you a lot of grief. If you don't have a server in the group to perform that task for you, configure one router to serve as the DHCP Server. Manual configuration of more than 5 computers on a network is a major hassle, not worth anyone's time.

Really good answer, clear and concise. Thank you.
I understand the DHCP bit in which you recommend me to use DHCP (which I see as a positive thing). The only question it comes to my mind is: "how do you get access to a computer if the computer's name doesn't give you access to it?" I mean that sometimes the only effective way to access a computer is trough the IP and not the computer name...

Oh dear, do you not have a DNS Server in the network?
You can manually add hosts to the Hosts file, but you have to do that for every computer in the network. You can enable NetBIOS over TCP/IP, too, to allow the old Windows network discovery tools to work. Unfortunately that exposes you to a bunch of attack vectors, and it's just a whole lot smarter to avoid all that. Some routers have a DNS Server funcion built-in, along with the DHCP Server functions. If you can't have a real server to control your domain, I'd really recommend installing a router that can do all these things for you.

We are going to be sharing a conference room with another company and would like both parties to be able to schedule the room with only visiblity into the room scheduling.
|
|
|
|
|
You've got a huge problem. Your two companies would have to share the same Exchange server infrastructure, meaning the Exchange servers would have to trust each other users. If you don't want anything other than the conference room being shared in Exchange, you have a massive security effort to keep the seperation in place.
If this is all too much, for a single conference room, put up a scheduling sheet in the room or have a secretary maintain it.

Maybe you can use an online calendar app just for this conference room like Google calendar

I'm using AnkhSVN and just recently RocketSVN but have the same problem with both.
I want to make some major changes to an application so I want to create a Branch.
The way I normally do this is that I created the Branch then switch and work from the Branch
but whenever I try to merge my changes back into the Trunk am not able for one reason or another.
Should I create the Branch then continue using the Trunk then Merge back if I want to keep changes?
This doesn't seem right to me so I haven't tried it.
I've used SVN quite a bit but I just can't seem to get the Branching through my head for some reason.
How should I/How would you do this?
|
|
|
|
|
that's a very good question!! i always have the same issues with branching and end up making a mess of the merge! ...hopefully someone with real svn expertise can advice here...
|
|
|
|
|
Yeah I usually end up deleting what's in the Trunk then I have a .bat file I run to
delete all the .svn directories then do an import. But that's so kludgy.
|
|
|
|
|
lol, definitely kludgy, there MUST be a better way!

read up a bit on the subject, you're supposed to use the "svn merge" feature (how you exactly execute this depends on your svn client, I use tortoise), the output of the merge will occur on your local copy of your trunk only therefore it should give you the ability to address conflicts before committing the merged trunk. should delete branch after merger is complete.
its always easier said than done though, i know personally there can be tons of conflicts! apparently it is suggested that occasional merges (weekly?) be done from the trunk to the branch so that the final merge from the branch back to the trunk can be a bit less painful. you can pick and choose what changes to merge from the main trunk to your branch (by specifying revision numbers to merge).

I have read quite a bit on the subject and thought that I followed the rules but like you say there is always a ton of conflicts.
Although what you have told me reconfirms that I am doing it right by branching and then working off the trunk.
Maybe I'm using it for the wrong purpose...I want to make a ton of changes and if it works and I like it I want to keep
it but if it doesn't work then I can just delete the branch or revert and go on my merry way.
|

|

well to clarify, the branch should contain your experimental stuff (not sure what you mean with "working off the trunk").
|
|
|
|

Here's a great little summary of branching:
http://blog.red-bean.com/sussman/?p=92[^]
...in this summary, they suggest just keeping your branch synchronized with changes in your trunk... btw, i'm looking this up because i really need to learn this too!

Thanks for the link.
I'm going to give it a try if you hear a loud scream in the next couple of days that would be me
just ignore it and drink a beer for me.

I have a windows 2003 box that runs IIS 6, a simple website built in asp - yes ASP *NOT* asp.net. I have no need or desire to rewrite it in asp.net (just to get this out of the way early on).
Today I applied windows updates to it and added .Net 3.5 SP1. Rebooted. Now the friggin web server won't let you download .exe's any more, which is a bit of a sticky wicket since this is what we use to get updates for our internal software.
I've tried checking the MIME-settings - they seem OK, there's a bunch of definitions in the top level "local computer" node in the MMC UI for IIS. The directory settings for the relevant parts seem to be - namely they are set to read only, directory browsing, and the Execute permissions are set to "None".
But when I try and request the file via a browser, I get error 404, sub part 0, win error code 2, file not found.
I've tried rebooting the machine, un-installing .Net 3/3.5, allowing/disallowing ASP.NET in the web service extensions, none of which make any difference and I'm out of ideas at this point. Any suggestions? Note that sacrificing a virgin on a full moon isn't possible here in NYC due to the extreme difficulty in tracking down virgins. I'll be happy to try just about anything else though!
>>the solution<<
Rename the directory where all the sub directories with installers were. voila, all working again. WTF!? 
|
|
|
|
|
Probably no way to confirm this now on your working system BUT (if anybody else ever has this issue...) was it just screwed permissions on those files / folders?
|
|
|
|
|
That's what I thought originally. I tried all sorts of things, and as far as I can tell, the permissions were OK.
