 - Dotnet >> c# lesson for c++ developersI was sitting on my porch reading 'c# Class Design' from WROX press and i
 thought this paragraph was interesting:
 
 ______
 Where reference types are concerned, C++ developers will need to get used to
 not thinking in terms of pointers. Although this is more-or-less what
 happens behind the scenes, the CRL moves objects around on the managed heap
 and adjusts references on the fly while the application is running. SInce
 we don't notice this at run time and it's no obvious from the source code,
 it confuses matters if you mentally try to tranlate between c# and c++ as
 you write.
 _____
 
 This to me shows what a radical break there is between c++ and c# and how
 being a c++ *guru* can be a real detriment to learning c#.

 - Microsoft Project >> how percent complete is calculated for nested summary tasksI remember a Microsoft tech document published in the mid
 90's that explains the algorithm used by Microsoft to
 calculate percent complete for nested summary tasks. Can
 anyone direct me to the latest version of it? and will the
 same logic apply to the rollup of %complete in grouped
 tasks?

 - ADO >> DateTime vs DateSince the .NET framework morphs both of these data types into being a
 DATE.... that jsut happens to have both a DATE and TIME component.....
 how do we tell.... which of these the data really is....... since the
 same object tests out as DATE and DATETIME ?
 
 The issue becomes one when we want to programatically create update
 parameters for updating..... as there are databases that will not accept
 the wrong string types..... and convert them on the fly.....

 - Microsoft Project >> Grouping Projects/Resource groupsHello,
 I'm using Project 2003 standard.
 I have several projects consolidated in one master project. My resources are
 divided in several groups: A, B, C
 Sometimes, theire are several ressource from different groups on the same
 task.
 Now, I need to edit Work statistics grouped by project then by resource
 group, on a monthly timescale.
 Such as:
 
 Project1,
 Group A
 Group B
 Project2
 Group A
 Group C
 
 But Project generates "combined" groups such as A;B that pollute all the
 statistics.
 How to avoid this? I tried the "Groups assignments, not tasks" option
 without success.
 
 Thanks for help

 I want to customize the dialog box that appears when you double click
 any entry in the address box dialog in
 
 outlook 2007. I searched the web with many saerch keys but no luck.
 
 The dialog box seems to show the properties of an ExchangeUser object.
 
 If anyone has Windows Live Messenger installed he will find the
 Actions button customized with 2 new items
 
 in the drop down action list.
 
 I think VSTO is the best way to go but I do not know where to start
 
 Appreciate any hints

 - Visual C#.Net >> Accessing Mapped Network Drive from ServiceHi All,
 
 I am trying to access a mapped network drive from a service that I have
 created.
 
 The service needs to create/delete folders/files on a network drive. When I
 tried to connect to a folder on mapped network drive (eg. N:\Storage that
 corresponds to \\FS1NS\SharedDir\), I get an error as "Could not find part
 of path N:\".
 
 I tried running the service in the Administrators account but the same
 problem. The thing works if I directly access the network share
 \\FS1NS\SharedDir\.
 
 Can anybody please throw some light on whats happening here? Is there
 anykind of restriction on access to the mapped drives when tried from a
 service (it did work from a C# windows application).
 
 Many thanks in advance

 - Visual C#.Net >> Calling Unmanaged CodeWe have a ton of code already written in C++ and the code
 is compiled into dynamically linked dll's. What is the
 easiest way to call this code, or is it even possible to
 call the code. We do export serveral classes from those
 dll's right now. Any direction on this would be
 appreciated.

 - Visual C#.Net >> Matching Same Results In Single StringI would like to use the Regular Expression search in the Find dialog in
 VS.Net to find a pattern in a code file. I am not sure if a pattern can be
 written for the Find dialog that matches my criteria though.
 
 Basically, I want to find all occurances of:
 
 i = i + 1
 
 where i can be any valid variable name, but all matches of i will be the
 same on both sides of the '='. So:
 
 a = a + 1 ' match
 b = b + 1 ' match
 c = c + 1 ' match
 d = c + 1 ' invalid
 c = a + 1 ' invalid
 
 If this is possible, what would the pattern be to match this? Remember,
 this isn't normal Regular Expressions, this is for the Find dialog in Visual
 Studio .Net itself (and not a program I am writing).
 
 Thanks,

Dotnet >> ZIP in .NET Hi..

My coleagues-programmers are coping with a problem. We want to find a way
to export our project (folder structure) into a single file.
We tought ZIP would be suitable for also utilizing a light compression.
Is there any free code or free library for C# that would support this
zipping, but including spanning, in case the date exceedes 2 GBs?
It must support the spanning. Withuout it, it is meaningless.

Thanks,

Kris

The only *FREE* ZIP Library I know of is #Zip at
http://www.icsharpcode.net/OpenSource/SharpZipLib/Default.aspx

However, their website prominently displays a banner saying that
developers with advanced ZIP needs should go look at XCeed ZIP
http://www.xceedsoft.com/products/ZipNet/ if they had advanced ZIP
needs (like support for streaming). It's $300 - but consider having to
write this yourself - you'd spent a lot more trying to achieve the
same thing yourself !

There ain't no such thing as a free lunch! :-)

Dotnet >> ZIP in .NET If you're using .Net platform 2.0, look at the System.IO.Compression
namespace. It has 2 classes, DeflateStream and GZipStream, which are useful
for compression and decompression.

 - ADO >> Jet database engine could not find the object 'Expr...'I have been connecting to MS-Access database using Jet 4.0
 from C#.NET. My application works finely on my computer on which I've
 made the application.
 
 But I observed a strange behavior. When I run my application on other
 computer that is installed .NET Framework, I get the following error
 "System.Data.OleDb.OleDbException: The Microsoft Jet
 database engine could not find the object 'Expr1007'.
 Make sure the object exists and that you spell its name
 and the path name correctly.".
 
 When I open Access mdb in the UI and paste the query string into the
 SQL window of the query designer and executes it, I get no error, the
 query results correct rows. I do this test on both other and my
 computer.
 
 What's the solution?
 
 Thanks in advance

 - Net Framework >> switch between local and remote (web) Business LogicHi Everyone,
 
 i need some ideas for the following problem:
 
 I am developing a three tier architecture. The client should be
 implemented in WPF to be able to easily port the application to a web
 application later on.
 
 The Business and Data Tier should be easily portable from local
 computer to a remote one somewhere on the web. So the only possible
 Link between Client and Business Logic would be a Webservice, wouldn't
 it?? In the local scenario I don't want to use a Webservice but only
 the usual construct of interfaces to connect the layers.
 
 What would be the best approach here ? Maybe you guys could push me
 into some direction ??
 
 I thought of implementing a second Assembly on the client which on one
 side the client connects to, to send and receive it's data and which
 can on the other side be configured easily to use either local
 connection or the remote Webservice connection.
 
 Thanks,
 Oliver

 It usually is in a background thread which polls the database every 30
 seconds, but it's happened when they were actually saving data in my
 application as well. Once, the server disappeared for a minute. Any
 idea what might be causing this problem? We're not having any power /
 router problems.

 - Microsoft Project >> messy gantt charts and ordering tasksHi,
 with projects with a large number of linked tasks it can quickly become a
 mess in the Gantt chart, as task orders are changed and added. I know it is
 possible to fix this by clicking on the task and moving it up or down the
 sheet, but this can become tedious with so many tasks. Is there any faster
 way to do this?
 Kind Regards

 - Net Framework >> dynamically determine .net baseframework version of exe or dllHi All,
 
 Whether in a Winform application (.exe) or a .Net assembly (.dll), is there
 a way to determine what version of the .net baseframework the run-time
 module (i.e. exe or dll) was loaded with (is using)? Seems that using
 reflection this is possible...just can't seem to figure out what
 classes/instances will get me there. Thanks in advance!

 - Net Framework >> line control in VStudio.NETLooking for the good ol' Line Control in Visual Studio.NET that earlier used
 to be part of the standard toolbox in VB6.
 
 Any suggestions.
 If there is no such control in VS.NET can anyone recommend a good way to
 draw lines on WinForms.
 thanks,

 - Dotnet >> RichTextControl Rtf propertyI have an application that simply reads the text in a RichTextBox control, and stores the text into the database. I want to use the plain RichTextBox control and not a database rtf control.
 
 When I read the Rtf property it returns the text combined with rft codes, e.g.:
 "{\\rtf1 ....... \r\0"
 
 I then store this text in my Access database via an OdbcCommand. When I read the text back from the database, the returned text is @-quoted as follows:
 @"{\\rtf1 ....... \r\0"
 
 When I try to set the RichTextControl Rtf property with the value from the database an exception is thrown.
 
 It would appear that the Rtf property cannot accept @-quoted values (e.g. a value of
 
 @"This is a test"
 
 will cause an error.
 
 How can I work around this problem while still using the RichTextControl in the scheme above.

 - Dotnet >> Problem Installing .NET 2003I have just opened and tried installing .NET 2003 after uninstalling Visual
 Studio Express .NET 2005. It goes to item 1 - checking for necessary
 components. I hav gone to Windows Update - every time it says that there is
 an Office Service Pack 2 update, which I have installed at least 5 times
 (every time I go to the Windows Update) and all of them say that to install
 was successful. I have used the Prerequisites Discnd done all of the steps,
 but no matter what I do I can' get past step 1 ????
 
 Any suggestions.
