Hello everyone,
I am trying to debug a Class Library. My question is:
Once the Class Library project is built and attached to a running process; using Module Windows, should I be able to see that MyProject.DLL file has been loaded?
Any information on attaching and debuging a Class Library project to a running process will greatly be appriciated.
Thank you very much and have a great day.

You would normally have your class library project in the same solution as the other projects you are working on. The debgging is seamless and flows through from one project to another.

Hello Colin,
Thanx for the reply. You are absolutly correct if the Class Library was created for an exsisting project. I am not able to do so since the Class Library is for creating a Browser Helper Object (BHO). That is why I am using Attach Process to attach it to IE Browser.
I am trying to undrestand the way Class Library works in Visual Studio, so I can solve the issue I am currently facing.
Thank you for taking the time and respond. Any information in regard with this is greatdly appriciated, Colin.
Have a great weekend.

SqlCommand cmd = new SqlCommand();
cmd.CommandText = "SELECT COUNT(*) FROM table1 WHERE id = @id";
cmd.Parameters.AddWithValue("@id", label1.Text);
cmd.Connection = myConnection;
int count = cmd.ExecuteScalar();
if (count > 0)
{
}

So you can do this:
IF EXISTS (SELECT * FROM MyTable WHERE SomeColumn = @SomeValue)
BEGIN
-- Do stuff here based on whether any rows exist.
END

Hi All/Luc,
Is there a Big Integer package in C#? I don't want to jump through API hoops to do big math (nothing like the suffering of attaching an image list to a tree view ). Next, is there a Bas64 Encoder/Decoder available in C#?
I seem to be pulling lower quality suggestions from Google. So rather than jump into it, I'll wait for the advice.
Thanks,
Jeff

Hi Jeff/All,
1.
there are several big integer packages publicly available. Maybe the most acclaimed one is
GMP (GNU Multi-Precision). IIRC its written in C++, I haven't seen a .NET wrapper for it though.
And there are some articles on CodeProject[^] covering this (with different capabilities and
qualities). Much depends on what it is you want to achieve.
2.
Not sure what you mean, maybe Convert.FromBase64String() and its sibblings will help you.

I wrote the first article.... I'll get a port together to C#. Do you want to coauthor? I'll have problems with the Managed/Unmanaged thunk. (This is my third day on C#.)

I'm a Crypto++ man myself. Years ago (circa 1998), I was never able to get a clean port of GMP to Windows.
Luc Pattyn wrote: Not sure what you mean, maybe Convert.FromBase64String()
Perhaps - I'll have to look at it.
Luc Pattyn wrote: Much depends on what it is you want to achieve.
This is going to be an article on Crypo++ interoperability with other Crypto Libraries and standards. The first article in this series is (somewhat out of order) is ASN.1 Object Identifier Encoding and Decoding[^]. It became such a large topic, it was spun off. In reality, it was supposed to be part of a Cryptographic Certificate Parser (*.CER, *.P7B, etc).
The TreeView is used for displaying results of the parser - the icons are a UI element aiding in vidualization of the message structure.

Hi Jeff, that's something we can look into. I'll send you an e-mail...

That is the cryptic message Microsoft has designed to tell you you don't have
(the right version of) the .NET Framework. So decide which version you need,
look for the download site and install it.

Someone voted you a 3 for that perfectly reasonable, logical and understandable question. Someone is obviously a moron.

Hi.
I have the follow:
1. System.Data.DataTable dt = new System.Data.DataTable();
2. dt = dal.Search(findfile.Text); // I receive the data correctly
3. dt.WriteXML(YourSearch);// I'm trying to create a xml file from the datatable
4. Response.TransmitFile(YourSearch);//download xml file
In the thirth row, when i run (compile ok) I receive
"Cannot serialize the DataTable. DataTable name is not set"
What that mean?
