I have to do a heavy load printing job...
In order to be ok with the clients, they want first to preview the printing, analize it, and then print it.
In my implementation I use a printPreviewDialog. When I show the dialog 1-2 minutes are wasted in order to generate the preview - this is OK so far... But when I press on the print button in the dialog, all the data that was readed previously is re-readed again wasting another 1-2 minutes...
Is there a way to print directly the data generated by the printPreviewDialog?
protected internal static readonly ... and I wish the list could continue ...

Hello gurus,
I'd like to know how can I retrieve the previous value of the SelectedIndex of the tab control?
I need to know the previous value before it is modified when the SelectedIndexChanged event of the tab is fired...
Can some one show me a code snipet for doing this please?
Best regards.
Fred.

Why can you not just store the data (int index) in a custom variable?

Hello,
I would like to store the encrypted password in the Windows Registry, and in my application I want to retrieve the password and decrypt it for further use. How can I achieve this.
Thank you.

Look at the Microsoft.Win32 namespace for registry writing.
Look at the System.Security.Cryptography namespace for encrypting and decrypting data.

I can access Windows Registry no problem. The problem is, I don't know how to store encrypted password in the registry, and when I want to retrieve the password, I need to decrypt the password as well. I figured that I have to use the Cryptograph class, but in what way to encrypt and decrypt the information I can figure out.
Thank you.

So where do you want to store the encryption key in order to decrypt it?
If this is a user password that the user must type in to gain access to something, then using a hashing algorithm is a much better idea. Hashing is a type of one way encryption (you can encrypt, but you cannot decrypt). So when the user types in their password it is also hashed and the two hash values are compared. The bonus is that you don't need to figure out where to store any keys in order to decrypt the data (because you can't decrypt the data)

I would like to store the password in the windows registry, and I want to use the password to access the SQL Server from my Application. So, user will never type in the password. The application will use a generic account to access SQL server and not per user basis. And I want to store the password in the windows registry.
Thank you.

In a form class module (Formtest) this is what I am doing in .NET 2.0:
AppBar.CCInfo.CanApprove
In AppBa there is a struct
the compiler is giving an error as follows:
Accessing a member on 'ChngCtrlUI.frmAppBar.CCInfo' may cause a runtime exception because it is a field of a marshal-by-reference class
Thanks

Try wrapping frmAppBar as a public property, making the field private.
Or, make ChngCtrlUI not inherit from MarshalByRefObject if you don't need remoting.

I'm brand new to C# and I'm trying to figure out how to parse a string. Is there a function available much like the explode() function in PHP which breaks up the string on a certain character and places the different parts into an array?
|
|
|
|
|
string s = "a,b,c";
string[] parsed = s.Split(',');

Well, one thing I'm doing is this. I have a String variable called 'filename' which contains the entire path and filename, including extension. I want just the filename, no directories or extensions. To do this, I have this one command:
String shortened = Filename.Substring(Filename.LastIndexOf("\\") + 1, Filename.LastIndexOf(".") - Filename.LastIndexOf("\\") - 1);
LastIndexOf() figures out the number position of the last one of that kind of character.
Substring() extracts out n number of characters starting at position m, where the arguments are .Substring(m, n)
C# isn't meant to parse out strings like PHP, PERL and others but I think you can find quite suitable alternatives using those methods and possibly others.

I'm using .Net 2.0 and for the life of me, I can't find the "Always Show Selection" attribute on ListViews. Did they remove it? Right now, the selection is only showing witht the list control has focus.
Can someone please point me to where they hid it?
thanks
