Creating a DataSet at runtime or at "design time" (which really just means that VS writes the code for you - it's still created at runtime) has absolutely no relevance as to whether an application can connect to a database. My guess is that whatever you're doing at design-time is causing your db connection information to be generated as well. If you want a

then just check out the code that Visual Studio writes for you after you drag and drop a DataSet onto the Form.
Please, don't ever ask for a full source code example. We have our own jobs.

You did not provide any information pertaining to the hosting process and context for the C# code and the scripting engine. Without that I don't know if anyone would be able to help.

foreach (string name in mylist)
{
Page.RegisterArrayDeclaration("listname", name);
} This will emit the following:
var listname = new Array('a','b','c','d',....);

I have the following callback function which I am using to update a progress bar. The only problem is, when I change the value of the progress bar, the bar doesnt change It just shoots to 100 when it is done. I have tried using Application.DoEvents(); .
private Int32 CopyInProgress(uint TotalFileSize, uint BytesTransfered, uint StreamSize, uint StreamBytesTransfered, uint DwStreamNumber, long dwCallbackReason, long hSourceFile, long hDestinationFile, long lpData)
{
float t = TotalFileSize;
float bt = StreamSize;
int nPercent = (int)(bt/t)* 100;
percentComp.Text = nPercent.ToString() + "%";
progressBar.Value = nPercent;
Application.DoEvents();
return PROGRESS_CONTINUE;
}
Any ideas why this is happening?

Yup, I got an idea.
You are converting a float (bt/t) into an int...then multiplying it by 100.
By definition, when you make it an int in this manner the answer can only be 0 or 100 and nothing in between.
try changing it to:
int nPercent = (int)(bt/t*100);

Nicely spotted! I was trying to find a reason why the message couldn't have reached the control. Tuh!

Not a problem. Even a crusty old C programmer gets to get one right once in a while.
The rest of the time I'm generally walking around C# and .NET like a complete idiot because so many of the rules have been changed that there's not a lot of advantage to having programmed for 20+ years...LOL.

Hello, I'm trying to view a webpage in a WebBrowser using DocumentStream.
The problem is about showing it. If I put the AllowBrowsing in TRUE, I can't see the page, only I see a blank page. If I put the AllowBrowsing in FALSE, I see the page but I can't make click on the links.
I write: webBrowser.DocumentStream = htmlDocument;
in the Load event. I've nothing in the URL property.
It's like the blank page is loading in the WebBrowser.
Any ideas?
Thanks a lot !!!!

How can we assing my custom event to a third party event;
I am using Secure Black box for PGP projects and in C++ I can do something like
Reader->OnCreateOutputStream = DecryptStreamNeeded;
Where Reader->OnCreateOutputStream is the third party event and DecryptStreamNeeded is mine so when OnCreateoutputStream fires it calls DecryptStreamNeeded.
In C++ the declaration above works.
I want to recreate that in C#
Here is the Third party delegate and event
event TSBPGPCreateOutputStreamEvent OnCreateOutputStream;
public delegate void TSBPGPCreateOutputStreamEvent(TObject Sender, MemoryStream Stream);
Here is mine:
//Delegates
public delegate void MyDelegateDecrypt(same params as above);
public event MyDelegateDecrypt MyDecryptEvent;
Here is my function i want to call
public void MyDelegateDecryptEvent(same params as above)
{
Stream = myDecryptStream;
FreeOnExit = false;
}
And now I'm stuck because at this point when myDecryptor.OnCreateOutputStream fires I want it to be redirected to MyDecryptEvent. So when I did this:
myDecryptor.OnCreateOutputStream = MyDecryptEvent;
and I get a type mismatch.

Probably I'm not getting you but you might search for this (assuming that weird 'removed' actually means 'OnCreateOutputStream'):
myDecryptor.OnCreateOutputStream += new MyDelegateDecrypt(MyDelegateDecryptEvent);
Unbdinging is nearly the same:
myDecryptor.OnCreateOutputStream -= new MyDelegateDecrypt(MyDelegateDecryptEvent);

Thanks, I will try this.
