I'm developing my first useful C# application, and I've come to quite a few points where I'm thinking "There has to be a better way to do this than what I'm doing", and this is one of those cases.
Often times when I load a dialog, I'll need information/objects from the main form in the new loaded dialog. Right now when I load a custom dialog from the main form, I do something like this:
CustomDialog dlgName = new CustomDialog();
dlgName.Loader = this;
dlgName.ShowDialog();
...
And then to access the main form's data in the CustomDialog example:
Loader.DataINeed;
Is there a special variable or other way I can access the main dialog's public objects from a new dialog without passing a reference to that main dialog's object?

Delegates/Events will do the trick, there are many articles here on CP discussing this. You should also look into creating your own EventArgs class which can be tied to your delegate. HTH

Hi,
I'm using a BindableListview for which I found the code on the web:
http://www.interact-sw.co.uk/utilities/bindablelistview/source
and I'm also using the ListViewSortManager found on Code Project:
http://www.codeproject.com/cs/miscctrl/lvsortmanager.asp
I have found a funny interaction between the two. After binding the ListView to the DataSource, when the ListView is re-sorted the data gets out of sync.
For testing purposes, I added a few simple controls which also bind to the same DataTable, for instance a TextBox and a CheckBox (one of the column is Boolean).
After setting the ListView and the Controls' DataSource to the same DataTable, the data is synced such that if I select an entry in the ListView, the TextBox and CheckBox show the proper values.
Now, after sorting the data using different columns, the data in the textBox and CheckBox doesn't show the same value as the selected item in the ListView.
I'm assuming this is because the DataBindings are using an index, and that re-sorting the ListView differently doesn't necessarly affect that index.
How would I proceed to "re-index" the data such that clicking an item in the ListView brings up the proper data in the textBox and CheckBox ?
Thanks.

As much as I can rememeber I set the width of Label to 0 then it was resize according to the text I gave ti it automaticly,Setting width of Label is kind of hard,it very depend on where do you pet the label like is it in a table cell and how do you set the properties of Table,Row or its cell.

Any suggestions on how best to retrieve a web page via an HTTP connection and then save/display the results as an image. I can get the web page as HTML okay within a stream but am not sure what to do with it next.
Any suggestions would much appreciated.
Cheers

I'm new to this but I choosed the way of 'Capture the screen'. The basics you can read here: http://www.c-sharpcorner.com/Graphics/ScreenCaptFormMG.asp
BUT there's a BIG problem with this: the browser screen/windows can NOT be overlapped !!!  If some windows is on browser windows so both of them will be on screenshot image! Nothing we can do about this. I choosed to make the browser window 'Top most' in properties but... this is not the way.. and the browser windows can NOT be hidden !! No screenshot in this case  (just empty space)
Another way is to go down and handle all HTTP POST/GET request by yourself but it's seems like a hard way You can check 'mshtml' class for this.
P.S. How did you get a HTML page on stream ? How did you open a stream to HTML page ? Can you send me a code ?

SearchResult result = mySearcher.FindOne() ;
if( result != null )
{
Console.WriteLine("User found");
foreach( string key in result.Properties.PropertyNames )
{
// Each property contains a collection of its own
// that may contain multiple values

Put the values into public properties and retrieve them after closing the dialog:
YourSearchDialog dlg = new YourSearchDialog();
if( dlg.ShowDialog() == DialogResult.Ok ){
yourResult = dlg.ResultProperty;
}

Hi All,
I have a solution where I have some of my classes written using MC++ and I'm trying to use those classes in my C# project, but I can't for the life of me figure out how. I'm not sure I have make the C# project aware of the classes. I think I'm going to need to use a "using" statement, but I don't know what it should be. The MC++ stuff is in an exe and not a dll so I don't think I can add a reference to it. Any help would be appreciated.
Thanks

If you're going to share code between apps/libraries, it probably should be in a DLL, not an EXE. That will probably solve your problem.

Sorry if this is a FAQ. What version of visual c# should I buy as an individual developer with a somewhat limited budget? I don't want to shell out $1,000 for visual studio if I can avoid it. What will I really miss by getting Visual C# .NET 2003? Any reason not to buy "Visual C# .NET Deluxe Learning Edition Version 2003" which includes "Visual C# .NET 2003 Standard" which I found for about $60? Thanks for your advice on this.

The learning edition is for students only and I don't think it can be used to produce commercial code.
VC# std ed should be fine, depending on the type of work you intend doing with it.

Are you sure about that? It looks to me like a bundling of a book and Visual C# .Net. Microsoft's web site doesn't say it is an academic version. See this link[^].

I see what you mean.
I'd contact your local MS office and find out exactly what version is in that book.
Cheers,
Simon

One of the things that concerned me was I want to be able to create windows services and web services. I tought I read that there were some limitations on doing this in the standard edition.
Also, will I be able to import ActiveX controls with the wizard?
Thanks. -- Bud

Correct, the standard edition is limited. Hence the drastic price difference between it and the pro/enterprise architect edition.
Occording to this[^] site, you can create XML web services, but I don't think that you can create Windows services though.
Cheers,
Simon

Would someone be able to give me the inside scoop on delegates and remoting? How hard or easy is it to use delegates w/remoting? What's involved? Any good articles and/or links on this?
From what I've gathered, you can use delegates with remoting, but it doesn't work very well with interface methods. Is this correct?

Selling your soul.
Have a look at my Plugin Manager article. I kind of takkle it there. Another thing that rings a bell, is the CrossAppDomainDelegate class.

Ok, thanks for the pointers! I'll look into that.
Basically, I'm wanting to know if one can have events or a similar type of notification system using delegates, with remoting.
Really, though, it's not that important - just that somebody on our team insists that remoting must be kept as an open option, even though this is just a GUI Library.
