Re: manipulate IE favourites Heath Stewart7-Oct-04 22:12 Heath Stewart 7-Oct-04 22:12  The easiest way - since Internet Explorer favorites are nothing more than .url link files - is to move, copy, or delete files from the Favorites directory, which you can easily get using: string favorites = Environment.GetFolderPath( Environment.SpecialFolder.Favorites); From there you can use various classes in the System.IO namespace - such as the File and Directory classes - to manipulate the file system.

Actually it can be recreated as follows: Create a VB6 COM dll with a method as follows: Public Function TestCSharp(ByVal sObjectName As String) As Object If sObjectName <> "" Then Set TestCSharp = CreateObject(sObjectName) End If End Function Now write a C# class to access it and write the following code CSharpTest.InterOpObjClass oObject = new CSharpTest.InterOpObjClass(); ADODB.Recordset oRS; oRS = (ADODB.RecordsetClass) oObject.TestCSharp("ADODB.Recordset"); It gives an error saying specified cast is not valid, basically an invalid cast exception Now try the same in VB.net Dim oObject As CSharpTest.InterOpObjClass = New CSharpTest.InterOpObjClass Dim oRS As ADODB.Recordset oRS = oObject.TestCSharp("ADODB.Recordset") This works fine. Why is C# unable to unbox the value? I have noticed this for all interop objects that return type Object. C# seems to treat them as System.__ComObject and I guess it does not like a conversion between System.__ComObject and ADODB.RecordSet or infact any other. Is there a way around this in C#?

I want to test my knowledge on the C# language, is there a free site where I can take a practice test. I already tried cert21, but the free test questions are very few. Sorry for my bad english. Thanks in advance Re: C# questions Christian Graus7-Oct-04 15:07 Christian Graus 7-Oct-04 15:07  Well, the obvious approach would be to read this forum, and answer as many questions as you can. I'm sure there are other, similar forums, probably a whole hive of them in the microsoft newsgroups.

More generally, this would be filtering to the child-most class. Matt Gerrans Re: Filtering the Intellisense Dropdown Alex Korchemniy7-Oct-04 14:10 Alex Korchemniy 7-Oct-04 14:10  I'm afraid that there are no built in options for that. There's probably a tool with intellisense the way you want to have it. But, most of the tools that I've tried are not too professional and make the VS.net more complex and probably more annoying than helpful. Anyone out there actually have a tool with better intellisense than VS.net? missing interfaces from tlb Member 12529757-Oct-04 12:26 Member 1252975 7-Oct-04 12:26  Has anyone run into a problem where you would register a C# project for com interop, look at the .tlb file that gets generated, and have all the interfaces in your project be missing? This is exactly the problem I'm having and it's driving me nuts. All other projects I've ever done the interfaces showed up like they should. I even have all their ComVisible attributes set to true. Any ideas? wrapping text in listview (detail view) vista277-Oct-04 11:59 vista27 7-Oct-04 11:59  i have a listview set up as detail view, and would like the text to wrap to next line for each column. i have LabelWrap set to true, but it still appends the "..." after the text. Re: wrapping text in listview (detail view) Alex Korchemniy7-Oct-04 14:00 Alex Korchemniy 7-Oct-04 14:00  According to MSDN: When the LabelWrap property is set to true, the item text is wrapped to the next line of text if needed. If the text is longer than two lines of text, the text is shortened. Seems like you're limited to two lines. You can rewrite the painting code. Constructor - Load method pat2708817-Oct-04 11:44 pat270881 7-Oct-04 11:44  Hello, I have a Form of a Smart Device Application with a constructor and a defined Form_Load event. When i the form is created which method is first executed - the constructor or the Form_Load?? regards pat Re: Constructor - Load method SandeepN7-Oct-04 11:51 SandeepN 7-Oct-04 11:51  You can quickly check this by putting breakpoint in both Constructor and Form_Load method and run it. See which one gets called first... Sandeep Naik Re: Constructor - Load method Matt Gerrans7-Oct-04 13:28 Matt Gerrans 7-Oct-04 13:28  Or with logic: does it make sense for any method to be called before a constructor? By the way, if you have multiple constructors and you're using the debugger method suggested, may want to put breakpoints in all of them. Matt Gerrans Re: Constructor - Load method Heath Stewart7-Oct-04 22:05 Heath Stewart 7-Oct-04 22:05  Yes, static methods and type constructors.

Software Design Engineer Developer Division Sustained Engineering Microsoft [My Articles] Re: Constructor - Load method Matt Gerrans8-Oct-04 6:45 Matt Gerrans 8-Oct-04 6:45  Well, yes, if you want to pick nits. If you insist, instead of "does it make sense for any method to be called before a constructor?" it should be "does it make sense for any instance method to be called before a constructor?" or perhaps "does it make sense for any static method to be called before a type constructor?" or maybe the two combined.
