I think the problem is the way you are reading data out of the memory stream. Use a stream reader instead of getting the bytes and doing unicode encoding. I suspect that is screwing things up. Then use a stream writer to put the string back into the memory stream when decrypting. (This works fine on my PC if I make that change)

You're not calling dispose no any of your streams. You should be using 'using' to properly dispose of the streams. Anything that has a dispose method should be created within a using block (or if not, make sure you call Dispose() in some other way - like in a finally block) Like this:
using (MemoryStream memStream = new MemoryStream())
{
using (ICryptoTransform EncryptorDecryptor = Algorithm.CreateEncryptor(key, iv))
{
using (CryptoStream crStream = new CryptoStream(memStream, EncryptorDecryptor, CryptoStreamMode.Write))
{
using (StreamWriter strWriter = new StreamWriter(crStream))
{
strWriter.Write(s);
strWriter.Flush();
crStream.FlushFinalBlock();
}
}
}
}
Also, you're using a bunch of member variables on the class that your just overwriting when you decrypt. Get rid of these and make them local variables in the method. That will prevent any crossover or leak of setup from one method to the other.

that depends on where you want to take it, although if I were you I'd be more concerned with figuring out "how to post intelligent question in forum?"

I want to know how to do the similar thing for c#?

I don't know the answer to this question but you can use DLLImport to use the method's from c++ as an exmaple I've done the following in the past
[DllImport("Gdi32.dll", EntryPoint = "CreateRoundRectRgn")]
private static extern IntPtr CreateRoundRectRgn
(
int nLeftRect,
int nTopRect,
int nRightRect,
int nBottomRect,
int nWidthEllipse,
int nHeightEllipse
);
hope that helps a bit

Hi
i've configured my typed dataSet for Insert/Update/Delete/Select with stored procedures.
my insert procedure returns pk of inserted record as output parameter. i use TableAdapter.Update method to insert/update/delete operations. my question is that how to get pk of inserted row when i use TableAdapter.Update ?
Note : i need pk of inserted record for update it's child table(s).
|
|
|
|
|
are you not using the PK field to identify which row it is you are updating?

Hi,,
i added a new form window using "Add new Item" option. the new added form display in the solution explorer. BUT it object is not available into another form why?
I am calling this form from Form1.
using this code
Form4 frm4 = new Form4(); // error line
frm4.Show();
it give an error "The Namespace Form4 could not found"
??? Why this gives the error?
|

Have you checked they are in the same namespace? I'm assuming that the new form is called form 4

i have data set linked with table adapter(which is already linked with table in the database)
and i have datgrid linked with the dataset and when i add values to the table in the db, the added values does not add to the dataset and so does not add to the data grid.
WHY?
|
|
|
|
|
I think the values which u r adding to the table in DB those are not reflecting in that table. Try like this, After adding values to the table
dt.AcceptChanges(); // dt means DataTable

How to read the large data(containig 2000 records) from binary file please anyone help me with code.
|
|
|
|
|
You are first going to have to find out the format of the binary file. We don't know this so can't really help beyond the basics of how to open a file for reading.

I think u can get it by dynamic creation of controls. First take a Panel in that u can add the controls one by one applying the height and width. By using LinkLabel control u can do redirection from one form to another. Definitely u can do in this way.

'while page loads' makes me think this is a lost ASP.NET question ?
