i want to encrypt the password fied in my database.
i use MySQL Server
is there anyway to do it by the database or i should make it in my code?

It should be done in your code. Add some salt, encrypt it, then store the encrypted byte stream in the database. When you want to check a users password, add the same salt to the attempted password, encrypt it the same way, then retrieve the password from the database and compare the two byte streams.

of course it should be done in the code...
for example md5() function in php...
and then it's easy to check passwords during authorization...

|
|
|
|
is there any equifilant function in C#

I am a fairly new to .net programming and I am wanting to pull similar data from an: access database, SQL database, and a mySql datbase - and combine the output to a repeater.
I can successfully connect to all databases and have a successful form for each one. But... the project would be so much better if I could just combine the data for output and not have the end user hopping around...
Does anyone have suggestions or pointers in the right direction for doing this?

For this kind of problems I use 2 dimentional array or some class that's similar to the 2D array as far as functionality goes.
Then get the results from database 1 add it to the array, database 2 add it to the array ... database n add it to the array.
You probably need to search the rows in order to keep the rows straight.

Which file?

I don't know if he meant .mdf file. I don't know why someone would want to connect a .dll to the database or server

You have to use the C interface that's built into the database manager you are using. In other words, it depends on what DBM you are interfacing to: Oracle, SQL Server, DB2, etc. They should provide a "C language developers kit" or some such thing, that will have the appropriate headers in it. It's not generic, although the SQL standard (the X-Open version anyway) has a few things to say about interfacing with C (and other programming languages also).

H everyone,
I installed Sql Server 2005 and it installed good but when I want to use of it,it shows this message
"An error has occurred while establishing a connection to the server.When connecting to SQL Server 2005,this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.(provider:Names Pipes Provider,error:40 - Could not open a connection to SQL Server)"
I get this error when I am tring to :
1- I go to on the Visual studio Data Menu then select Add new Data source then select Database and click Next button then I click New Connection and select Microsoft SQL Server now it want Server name I enter server name and then I went to Select or enter database name but It didnt show any thing to then
I select Attach a databse file and enter a file(its extenstion mdf) and when I click ok I got above error
Is it possible I am getting this error because I enter wrong server name if yes how can I find correct name of server.
Thanks

Did you install SQL Server on your local machine or on a seperate machine?
|
|
|
|
|
I installed on my local machine.
|

Then you don't need to enter the server name, you can just enter '.' (a full stop), that corresponds to the local server.
Note: if you installed SQL Server 2005 Express, then you should use '.\SQLExpress' as the server name.
If this doesn't work, check if the SQL Server service is running.

It sounds to me like you have installed the freely available version SQL Server Express 2005, not the full version of SQL Server, is that correct?
By default, unlike the full version of SQL Server, this does not come with SQL Server Management Studio, which is used to create databases and enter SQL queries.
You can either open a command prompt and type sqlcmd -S.\SQLExpress -E to get a command prompt from where you can enter SQL statements against your database.
Or, you can download the freely available SQL Server Management Studio Express, which gives you a graphical interface to do all this (recommended).
Get it here: http://www.microsoft.com/downloads/details.aspx?FamilyID=c243a5ae-4bd1-4e3d-94b8-5a0f62bf7796&DisplayLang=en[^]
Hope this helps,
Roel

Thank you yes it was help but I'm sorry to interrupt again I saw your link and I want to donwload "Microsoft SQL Server Management Studio Express"
if I download it Can I sure that I will not problem to work with sql 2005(of course my intent is like previous ) ?
|
|
|
|
|
As far as I know, the only time it will not work is if you have the full version of SQL Server Management Studio installed already, which for you is not the case (otherwise you would not have to install this one.) So, just go ahead and try.
