Where is this data set filled ? It has the same name in Form1, but I don't see it being set in either. i.e. I don't see where this object is defined, so you'd expect it to be shared between forms of a different type.

No, I have no idea why it is that you can call this.gempanDataSet on two forms and expect them both to be the same object. I don't even see where i is being set ( maybe that's the problem ? ). Either way, some sort of global nastiness seems to be going on ( although that doesn't explain why you can use 'this' for gempanDataSet).

Why do you keep doing this ? Did someone tell you it was a good idea ? It's pointless.
Profile f2 = new Profile();
f2.Show();
In any case, if you want to show a modeless dialog, f2 needs to be a member variable, not a local one.

No, I pass datasets around all the time. The problem is that your code is broken. I still don't understand what you're doing and how. Do you?
arifliminto86 wrote: because i want to make like email program after i log in i can change my profile or my password thats why i need to use same database
Your data access should only occur in one place, as I've said, you should have a data layer in your code.
arifliminto86 wrote: sorry iam still beginer thats why sometime the way you talk i dont clearly understand
Sounds likely you're biting off more than you can chew. Too many people say things like 'I'm a beginner and I'm trying to write an email program'. If you can't understand the advice, you probably need to write something simpler first then come back to this project.

At the beginning of your file write
using System.Collections.Generics;

He's using VS2003 though. That's .NET 1.1, which didn't include generics.
|
|
|
|

That is because generics are only available iwth .net 2.0 (2005). 1.1(2003) doesn't have them.

Yeah but nobody knows that because the hide information like that in the Documentation[^]

Really? Looking at the top of the documentation link you included I see:
Microsoft Windows SDK > .NET Framework 3.0 Development
I would not call that hidden and it definitely does not point back to version 1.1.
|

Yes, it's hidden. It's very common to hide information in places like that. Throughout history intellectuals have always hidden information in cleverly disguised places, like books, essays, articles, reference manuals and documentation. Places where no sane mane would ever look for it. 
It's said that the best place to hide something is in plain view, and I believe that this goes for documentation on the web also. If the microsoft documentation had an url like http://www.killbill.org/misc, I think that a lot more people would know about it.

I hope you realize my post is aimed at people who don't read the documentation (there are tons of them on CP). My use of the word "hide" is sarcasm.

Hi!
I have a problem!
I want to work with one of the check objects in multiselect mode.
I tried using the CheckedListBox but the .NET writes that it does not support MultiSelection, any ideas about the componenet that is already exists?
An object that gets automaticaly a scroll bar if it is too large for the form size, not stand alone radio buttons.
Thanks 
|
|
|
|
|
What do you mean when you say that it doesn't support MultiSelection? If you mean checking more than one box, of course it does support that.

I am writing a client/server application that uses the SslStream class to provide a secure communications channel.
I have got the communications working, and the server certificate validation works fine (this is using self signed certs. generated by MakeCert.exe thanks to John Howard's blog http://blogs.technet.com/jhoward/archive/2005/02/02/365323.asp).
I would like to perform client certificate validation. I have generated certificates on the client in the same way as I did on the server and set the clientCertificateRequired parameter = true in the AuthenticateAsServer method as follows.
sslStream.AuthenticateAsServer(serverCertificate, clientCertificateRequired, SslProtocols.Tls, false);
When the server hits this line I get an exception:
"The remote certificate is invalid according to the validation procedure."
I have searched and searched and all I can find is stuff to do with IIS and web services.
Does anyone know what I have to do to get this working.
Thanks in advance.

Hi there;
Please help!!!! I am processing SQL select statement using a datarow and I would like to compare column values of current datarow with the previous datarow. Is there a way to do this?
Please Help

Remember that there is a DataRowCollection Class that wou can instantiate and compare in a cyclic manner with the previous instance.

Does anyone know how to or know of a tutorial to programatically zip a file?
I have a series of images that need to be able to be placed in a zip file so the user can download it to their hard drive. Manually zipping these files won't work in this situation.
Thanks.

Use the SharpZipLib library

Hi,
I downloaded the library. But there are so many classes and interfaces, I got confused how to start using this library to create a zip file and simply add files into that. also how to unzip a single zip file.
Is there any snippet available about the usage of this library ?

Probably on the #Develop website is the best bet
