No, it's not possible. Use MDI instead.

Hey Heath,
Not sure if you check out the ASP.NET board at all, but I'd really appreciate your take on a question I threw up there, considering you've basically committed the .NET framework to memory and all...

I try to steer clear - there's far too many questions about client-side stuff, and the majority of people just don't understand what ASP.NET is. I typically spend more time explaining why you can't popup a window using pure ASP.NET than anything.
I'll check it out, though.

Urgh.
Ok thanks for the fast reply.
Btw. is there anyway using MDI forms to remove the borders, and then show the form in full size so its not possible to see that its MDI?
I have only played around with alittle so its only a thought before i look closely at it.
cheers

Not easily, no. For that you really have to understand the Windows messaging system, styles, P/Invoke in .NET to use all that, and dialog resources in Win32.
I would suggest re-designing your controls. You could, for example, use a UserControl or some other Control derivative and just dock it (using DockStyle.Fill). If the UI and implementation is already in a form, then abstract them to a UserCotrol (or something) and use that in both forms.

What do you mean by "terminal"?

Hi people, hope you can help me.
I have the following code
public class TestDS : System.Data.DataSet
{
}
public class DataSupplier : dalBase
{
public DataSet GetSupplierList()
{
HybridDictionary parms = new HybridDictionary();
return Factory.GetDataSet("GetSupplierList", parms);
}
public TestDS GetSupplierList()
{
HybridDictionary parms = new HybridDictionary();
return (TestDS)Factory.GetDataSet("GetSupplierList", parms);
}
}
The first method works fine and returns a normal dataset. However, I need to create a strongly typed dataset hence the casting in the 2nd method to my own subclassed dataset. Trouble is when I run this I get a the dreaded 'Specified cast is not valid' error.
I was sure that I should be able to do this but it just doesn't work. Any ideas anyone?
Cheers
Paul

First, it is not CLS-compliant to have more than one method with the same name that differs only by the return type. Instead, rename one or both of your methods, such as GetTestSupplierList or something more suitable.
Second, your DataAdapter (or however you're filling your TestDS) should actually fill an instance of that TestDS class. So, perhaps add a Type parameter to your Factory.GetDataSet method, something like this:
public static DataSet GetDataSet(string storedProc, IDictionary parms, Type dsType)
{
if (dsType != typeof(DataSet) || dsType.BaseType != typeof(DataSet))
throw new ArgumentException("Not a valid DataSet type.", "dsType");
DataSet ds = (DataSet)Activator.CreateInstance(dsType);
}You should be able to cast it, since the return of GetDataSet still returns a DataSet. Such a method works fine in our enterprise application.

My first C# development at work needs to connect to a unix box and transfer files (both directions) using SSH (secure shell) and SCP (secure copy). Can anyone recommend a product/component/code to do this? I've come across Putty and SSHActiveX etc but I'd like a .NET solution if at all possible. Thanks.

I bind a arraylist to a datagrid which works fine. However when I modify data directly in the datagrid it isn't updated automatically to the ArrayList.
QUESTION
How can I force that a modification/update to a datagrid field will update the ArrayList immediately?
Regards,
Uyen Chi

Data is committed when the column is committed. This is the way that the DataGrid works. There have been many discussions about this in this forum before if you care to search. Just click "Search comments" directly above the message board.

Please look at the snippet
-----------------------------------
1 RichTextBox rtf = new RichTextBox();
2 Bitmap img = new Bitmap(@"c:\myImage.bmp))
3 Clipboard.SetDataObject(img);
4 rtf.Paste();
------------------------------------
when the program control passes line number 3 and if I copy some other text/image in the Clipboard using "Control + C", the earlier image 'img' gets vanished. Is there any way to lock the clipboard for other operations till I paste the image 'img' in RichTextBox?
Please Guide

Can the use of GlobalLock solve the purpose?
If yes, then how to use it in C#? how to get Handle to Clipboard ?
please guide
|

No, because the clipboard contains pointers to objects. All GlobalLock would do (and you'd P/Invoke that like anything else, using GCHandle to pin reference types in memory) is lock your object to prevent it from being overwritten.
The problem you're facing is a problem that all application face. Either use a clipboard ring like Office has (and manage that yourself - ever so carefully) or learn to deal with the consequences as every other application does.
The best way is to avoid using the clipboard when you don't need it. Marshal objects to other processes and what not when possible.

Hi all,
I have just moved some Enumerations from one assembly to a new one. However, the solution no-longer builds, as the enum's have suddenly become non CLS-Compliant. Moving them back to the old assembly fixes the problem! Is it really the case that you cannot use enum's from different assemblies?
I have google'd for the problem, but the only things I could find said to explicity define the enum as type int, which I have done without success.
Any ideas?
Thanks in advance,
Simon.

I use enums from different assemblies all the time. In fact you probably do too when ever you use an enum from the Framework itself.
Can you post the exact error message? It might help narrow the problem.

Thanks for your response.

Yes, I realise this, which is what makes it even stranger (to me anyway!).
Ok, to recreate this problem create a new solution and add two new projects (I added a class library (proj1) and a windows control library(proj2)). I added a new file to proj1, which contained the following enum definition:
<br />
public enum MyEnum<br />
{<br />
Monday,<br />
Tuesday,<br />
Wednesday<br />
}<br />
In UserControl1 in proj2, I added a new property of Type MyEnum. This builds successfully. I then added the line:
<br />
[assembly: CLSCompliant(true)]<br />
to the AssemblyInfo.cs file (and added using System;)
Now re-building gives this error: "c:\Working\testenum\controls\UserControl1.cs(43): Type of 'controls.UserControl1.Day' is not CLS-compliant".
Any clues?
Thanks again for your help,
Simon.

Did you add the line: [assembly: CLSCompliant(true)] to both projects?

No, I thought I had tried that, but obviously not because it now works!! Thanks very much for your help - most appreciated!
