WCF Questions - In Depth - C# - Web Development Discussion Boards

Go to ParentThank you for your reply. I have found the problem.
The problem was caused by the web server, because it didn't accept ASP.NET version for my project. So I have to choose another provider.

Sorry for repost, I thought I have chosen the wrong category.

i am presently working on a web application using php, but i dont know how to limit the number of users connected to the system via a router. Please is there a way to go by this? Any answer would be appreciated.. thank you

How to define +91 as default value on TextBox in simple html, and what the good way when we have to save in database

can you explain a bit more? Do you want to prefix +91 country code with your textbox value here?

Please do not crosspost.

Just put value="+91" on the textbox and that will default it.

There are only 10 types of people in the world, those who understand binary and those who don't.

Hi,

Scenario: Windows forms application is the client talking to a WCF service exchanging sensitive data in both directions

1. Transport Security
• SSL using server certificate with Anonymous client authentication - is encryption of message optional?
o What ensures that the message is definitely encrypted?
o Symmetric key is negotiated for message encryption, but what controls the strength of this key 128-bit / 256-bit etc.?

• If an additional layer of custom encryption/decryption logic is implemented along with SSL, specifically for message security, are there any drawbacks?

2. Message Security
• When message security is enabled over HTTP (no SSL) and a server certificate is provided in the configurations, how is the message encrypted/decrypted - with what key and how is the key exchanged?

• When message security is enabled over HTTPS (with SSL certificate) is the encryption/decryption happening twice?
o Is it possible to configure an Anonymous client (no client certificate/authentication) in this scenario?
o Is it possible to configure different certificates for SSL negotiation and for message encryption/decryption?
o What key used for message encryption - same as SSL negotiated key or new key based on the provided certificate?

3. SSL Server Certificate Validation by client
• By default, client validates the certificate during initial handshake - what all information of the certificate, exactly are validated and what are not validated? This validation is done by whom – .NET framework on the client or the OS itself?
o How different is this validation, from X509Certificate2.Verify() method call on the certificate, if done explicitly?

• In client code, if the callback to ServicePointManager.ServerCertificateValidationCallback delegate is registered, does this method get called before or after the automatic validation of server certificate?

Thanks in advance for your help.

Skipper: We'll fix it.
Alex: Fix it? How you gonna fix this?
Skipper: Grit, spit and a whole lotta duct tape.

sorry about it its a computer malfunction and I thought that it didn't send, so its not by intention..

Don't know anything about the level of your knowledge of the above-mentioned technologies, but judging by the list itself, you can at lease build an MVP and then see if you need any further help with it.

Hi,

I have a question please..

I have a table stored_photoz and I want to just display it in a page with 4 columns for every row only? How can I do this please using PHP?

Thanks,
Jassim

First, the column value should be assigned to a variable. Then with a foreach for each row or with a for loop, you can list those images.

Hi,

I want to ask for web development, which of your prefer for columns and rows? using table tag or dl tag?

Thanks,
Jassim

That depends on the data.

In opinion, table tag is the most common and ideal for that.

I want to restrict user at certain height and width. Tried implementing window.ResizeTo, but it doesn't work on chrome and when multiple tabs are open.

My goal is NOT allow user to shrink browser window beyond certain height and width.

Please Advise.

No. That's user-hostile; don't do it.

Thanks for the reply. I also didn't like the idea. Smile | :)
