C# loses variable's value on postback

Problem
C# loses variable's value on postback

Impact
can't get variable's value.

Solution
C# is executed on server and then it sends result to the client using HTTP protocol.
and as you may know HTTP protocol is a stateless protocol.
so after sending result to the client the server doesn't know what was the value of that variable on previous request.
so if you want to store that variables value then you can use session or viewstate or hidden field.
and you can get back that value upon postback.

JavaScript doesn't shows the full path of the select file

Problem
JavaScript doesn't shows the full path of the select file

Impact
can not get the full path of the selected file.

Solution:
if you are not getting full path of the selected file then probably you are using firefox.
because of the security reasons it doesn't stores the full path.
and just for your knowledge you never need full path.
the reason behind that is that if you want to upload a file on the server we need to use multipart/form-data ‎so it stores the entire file in the post array of submission.
so on the server side anyway you can get the file don't worry about the file path.

.net - can not connect to oracle server via my web hosting..

Problem
.net - can not connect to oracle server via my web hosting..

Impact
Can't fetch any data from the server and on the webpage it shows an error.

Solution
oracle support was deprecated by the Microsoft.
so what we use on our local machine is the oracle support for the .net
as it is the third party add-on so no hosting company provides oracle support as it may be unsafe.
so to have oracle support you must buy an dedicated server then your hosting company will do anything that you tell them to do and will install all your add-on.
but if you still want to use oracle on your shared hosting you can but you need to have permission to have trustlevel "full" over the server. and then if you have that you can upload dlls for oracle in to your bin folder and your web.config file should point to these dlls.
Working with these dlls will be quite tricky as there are  7 dlls that you need to upload on the server and still it doesn't support some functionality like ADDWITHVALUE function for parameters.
 and you will face some problem while working with int parameter.
but the way is to use for that is don't use parameters and build a query using sting and it is really unsafe to and easy to hack.
