Hi All,
I want to use an unmanaged dll with in an aspx page (with c#). I try the below code that I am sure it works with a console program.
<br />
<br />
[DllImport("myapi.dll", CharSet = CharSet.Auto)]<br />
public static extern IntPtr function1(); <br />
.<br />
.<br />
.<br />
function1(); <br />
<br />
How could I use this dll with asp.net. Or do you have any advice to integrate a type of any other project with asp.net to use this dll. Also I need a second adwice on working with an exe, in an aspx page.
thax a lot.

Hi all,
I want to encrypt and decrypt some data in Database.I got i code to the same but if the input string length is 16 then it encrypts in double length, I mean when I input string of length 16 : XYZXYZXYZXYZXYZ1 then the output is is of length 32.
Please help me.
Thanks in advance...

The problem is that If I input string of length 6 then the encrypted string must be of length 6 only....
Hope u got the problem...
|

Why? Is this a limitation on your DB field size?
You'll find that any encryption that is at all hard to break will increase the length of your unencrypted string. Otherwise you're just going to be using a simple letter replacement cipher that any bright 3 year old could break.

Hi Paddy,
Ya I know this but I will have to change almost all the field size of Database which I want to avoid.If it is possible then please tell me the solution.
Thanks.

If you want to encrypt items in this way, then you shouldn't be too pushed to write a simple letter substitution encryption - I'm sure you can find something like this on the net. But i'd really question the value of doing this, all it's going to do is slightly slow your application down, without providing any real protection...

Why did you post this in the ASP.NET forum. This is purely a SQL question. It should be posted in the SQL Forum.

hi as you guys should know the standard provider create database and table wit called
ASPNETDB.MDF(database)
aspnet_Membership(table)
i would like to change the names to
datadb(database)
membership(table)
is tis possible and if it can anyone outline the steps involve to do this pls
|
|
|
|

1. Create a database named datadb
2. From the Visual Studio Command Prompt run aspnet_regsql
3. Choose "Configure SQL Server for application services"
4. Select server and database
5. Add a connection string to the web.config file to this database
6. From the %SystemRoot%\Microsoft.NET\Framework\v2.0.50727\CONFIG directory open machine.config file
7. Copy-paste the membership part of the system.web section to your web.config's system.web section
8. Change the name of the provider and the connection string property to your previously added one. Set the defaultProvider property to the name you gave the provider. Example:
<membership defaultProvider="MyMembershipProvider">
<providers>
<add name="MyMembershipProvider" connectionStringName="MyConnectionString" ... />
</providers>
</membership>
This takes care of the first part (custom database name). For the second part you should simply rename the table in the database, then also change the name in the stored procedures created in the database. Hypothetically this should work, but I can't guarantee it will. I think it's worth a shot though.

when u say Visual Studio Command Prompt on step 2 do u mean the normal command prompt or a command prompt within Visual Studio
as i didnt know know visual studio got 1
mind telling me where =P

soo if my connectionstring is
<br />
<connectionStrings><br />
<add name="HASDBConnectionString1" connectionString="Data Source=kingster\SQLEXPRESS;Initial Catalog=datadb;Persist Security Info=True;User ID=sas;Password=password"<br />
providerName="System.Data.SqlClient" /><br />
</connectionStrings><br />
<br />
then my membership provider would be
<br />
<membership defaultProvider="MyMembershipProvider"><br />
<providers><br />
<add name="MyMembershipProvider" type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="HASDBConnectionString1" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="true" applicationName="/" requiresUniqueEmail="false" passwordFormat="Hashed" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="7" minRequiredNonalphanumericCharacters="1" passwordAttemptWindow="10" passwordStrengthRegularExpression="" /><br />
</providers><br />
</membership><br />
because i tried this and it just created another db wit the name aspnetdb.mdf
i am guessing i went wrong somewhere
