    - Best way to View MSIL Code From Existing Code Peter Ritchie wrote: There are other requirements of try blocks that would minutely affect performance. For example, while in C# you can have a return statement in a try block, this can't translate to a IL RET opcode, RET is illegal in a protected block and LEAVE.S must be used, which effectively jumps to a RET. So, the existence of the try block affects how IL is generated for the same code outside of a try block. Depending on target processor, this may or may not have a noticeable (although negligible) affect on performance. What's the easiest way to view my C# converted to MSIL It definitely sounds like having an idea what the IL equivalent of one's C# code will be can be beneficial. Tag: Visual C# Language MAPI in C# ?

    - Getting method name on compile time Are you sure about that I was convinced when you check 'optimize code' the compiler would inline, unroll loops etc. Why else would overriding methods at derived classes break inlining it it doesn't inline in the first place Regards John Tag: Visual C# Language MAPI in C# ?

    - problem in starting windows service Hi, I am using Windows Service for the first time.Already the .NET project code and the windows service was developed by someone else.I am trying to use this right now.I think that the windows service starts and reads the values from the registry key called ServiceTimerMinutes .The windows Service checks this registry key value and starts the batch processing of the xml files in the .net project. Basically ,an xml file is uploaded using .net project code.I don't have any problem in doing this .But I have problem in starting the windows service that is used to do the batch processing , and the results of batch processing can be seen from the .aspx page(in a datagrid )in the .net project.Windows Service is used to run scheduled batches to process the XML files. Since my team mate did not have any problem in starting the Service,I am really confused where the problem is..I really don't understand what u mean by .Net1 or .Net2 is the target I have .net framework version v1.0.3705,v1.1.4322 and v2.0.50727 installed. Please guide me. Thanks, cp Tag: Visual C# Language MAPI in C# ? Visual C#

    - [Serializable] Attribute That part of the serialization depends on the formatter. For example, if you use The BinaryFormatter the first part of the stream is 139 bytes of version/type/ID information so the BinaryFormatter knows how to create the type. i.e. the assembly name, the type name, and ID of the object in the stream (there may be more than one object of the same type). It may also contain file header/footer information to aid the BinaryFormatter in deal with streams written by different versions of the BinaryFormatter. The SoapFormatter would output an element for the object describing the assembly name and the type name as attributes of the element and field values as sub-elements of that element.

    - Confused about how default indexers property works Hi programmers I found this example which covers how default indexers work http://pietschsoft.com/Blog/Post.aspx PostID=1357 I can’t see how it works. At the very end of the article the author says: // Change the name of the first Person in the People // collection using the Club objects Default property club[0].Name = "John" ; But does the default property get called at all I out commented the Set method in public Person this [ int index] and it still works. But if I do the same with the Name property in the Person class I get compile error. This means that the default property (set) never gets called. Instead it is the property of the Person class that gets called( ) Im having the exact problem with my code, so I would be really glad if someone can sort this out for me. I saw another example which would equivalent with this call: club[0] = "John"; But in that example there were no Properties other than the default index property. I got compiler error when I removed the Set metohd: "Property or indexer XXXXXXX... cannot be assigned to - Its read only". Plz give explanation // Lennart Tag: Visual C# Language MAPI in C# ?

    - C# COM entry point function Hello everyone, I am a developer from C++ COM to C# COM. I feel confused about the entry point function for a C# COM object. In C++, we always initialize object through GetClassObject or DLLGetClassObject, but it seems C# does not need these functions Here is a sample from MSDN. http://msdn2.microsoft.com/en-us/library/aa645738(VS.71).aspx So, in C# do we need to implement the required functions like GetClassObject If no need, which function is the entry point for C# COM object -- I want to find the entry point function so that I can verify that my C# COM object can begin to talk with other COM clients. thanks in advance, George Tag: Visual C# Language MAPI in C# ?

    - AppDomain creates confusion Can any please tell me difference between AppDomain and Process in .Net context. I mean I am reading a book which says AppDomain is the new boundry for application execution and we can have more than one AppDomain in a process. If my application (means exe) is executing in an AppDomain than what is a process in which I can create another appdomain means can execute another exe. The book(Professional C# 2005 Wrox pub) further says AppDomains cannot access object directly in another AppDomain without a proxy (proxy ) but the same book gives an example( that works) in which a AppDomain is created and constructor of a class in another assembly is called(through CreateInstance) it sounds consfusing.

    - Solution Explorer where did New Folder go? It appears that in visual Studio 2005, the new folder feature found in visual studio solution explorer has been replaced with "new filter". While I find filters fun and nice to use, I find this feature not able to do what I could with the new folder feature in 2003 We basically have a very large project and we want to create "sub-folders" off of that project as to group the different areas. An example would be something like... Toy Store Project Balls - In this "sub folder" is all the .cpp, .h, and resx files etc having to do with balls Video Games - in this "sub folder" is all the .cpp, .h, and resx files having to do with video games. Matchbox Cars - and finally in this sub folder would be all the .cpp, .h, and resx files having to do with matchbox cars. I realize I am using .cpp etc.... because I looked and didn't see a ide of c++ but figured it would be close to c#'s IDE. Does anyone else miss the sub folder feature Is there a switch or some method to turn it back on Still No feedback Surely someone has to know the answer for this Tag: Visual C# Language MAPI in C# ?

    - HELP Needed on COM Interop Hi All, Need help with COM Interop. I am trying to use interop and perform automation on a COM DLL. In the process, i need to type cast an Object into a Class specified in COM DLL. When i do the same in VB it works fine. However when i typecast using C# , i get the following exception. System.InvalidCastException: Unable to cast COM object of type 'System.__ComObject' to class type '<ClassName>'. COM components that enter the CLR and do not support IProvideClassInfo or that do not have any interop assembly registered will be wrapped in the __ComObject type. Instances of this type cannot be cast to any other class; however they can be cast to interfaces as long as the underlying COM component supports QueryInterface calls for the IID of the interface. i get the same exception when i try to typecast to the interface. Surprisingly, since i donot need to typecast in VB explicity, i am able to typecast. Can you please help me nail this. Am i doing something wrong Regards, Swaroop PS: am trying to perfrom automation of a COM Dll that comes with a tool called Extensis Portfolio. Tag: Visual C# Language MAPI in C# ? Visual C#

    - events and handlers My post was really trying to answer a couple of questions. 1. Does an object reference count include the function pointers that a delegate holds (i.e. do I need to remove them ) which from the above would be yes. 2. If i were to remove the handlers from the delegate mid event would they still get called from another post in the c# general section the answer is yes (My posts didn't seem to appear.....so I posted twice) My aim is to ripple change though a graph of objects, however I think I am using events where I shouldn't be. At best I would be able to build a list of objects to process post event, and even to allow that - due to the fact the data is representing a graph - I would need to store an event state (i.e. has this object already been processed) to avoid an infinite loop which starts to sound overly and unecessarily complex.

    - How do I transfer data to an Excel file Hi Mahesh, I have found out quite a lot this morning. I didn't get a DLL file saved in BIN\DEBUG until I 'built' the dll. Fair enough. When I did get a dll saved, it is called Interop.Excel.dll The line using Excel = Microsoft.Office.Interop.Excel; still causes an error . 'The type or namespace name 'Interop' does not exist in the namesapce 'Microsoft.Office'. The definitions in the KB file, such as private Excel. Application m_objExcel = null ; need to be changed to public static Excel. Application m_objExcel = null ; otherwise I get errors in the program lines, such as m_objExcel = new Excel. Application ();. Error is ' An object reference is required for the nonstatic field, method or property 'AnnsonExcelDLL2.WriteExcel.m_objExcel' The upshot of all this is that I am making progress, but it is the progress of a blind man in a dark room!! Is there any documentation anywhere that explains lines like m_objRange = m_objSheet.get_Range( "A1" , m_objOpt); I can understand what it does and I can understand how to adapt it to do what I want it to do, but not where it comes from and how to create the line in the first place without looking at a KB file Many thanks John Woodiwiss Tag: Visual C# Language MAPI in C# ?

    - Warnings and classes Yes, it matters that the class isn't public. The only way to access the "Year" field is from an instance of the "Car" class. However, as the "Car" class is not public, it can only be instantiated within your project/assembly. Thus the compiler knows everything about how the "Car" class is used, and by extension, how the "Year" field is used, and can state with absolute certainty whether it is ever assigned to or accessed. As a field that is never assigned to or accessed is quite useless and probably a mistake, the compiler generates this warning. -Tom Meschter Software Dev, Visual C# IDE Tag: Visual C# Language MAPI in C# ?

    - Problem showing int from another class Hello, I am developing a console text game. Here is the problematic code for it. Code Snippet using System; namespace CoolGameTextClean { class Engine { private static Player MainCharacter = new Player(); public Engine() { MainCharacter.StartingLevel(); } public static void Main() { Console.WriteLine(MainCharacter.DisplayLevel.ToString()); // Displays 0. It should display 1 Console.ReadLine(); } } } Code Snippet namespace CoolGameTextClean { class Player { private int Level; public int DisplayLevel { get { return Level; } set { Level = value; } } public void StartingLevel() { Level = 1; } } } The problem is, in the Main method, I want to display the Level of the MainCharacter. In the constructer, I call the StartingLevel method, which sets the Level to 1, however, when I run the program, it displays the level as 0. What am I doing wrong Can someone tell me Thanks.

    - Language suggestion: try using {} catch {} finally {} Greg Beech wrote: In well designed and written code with a clearly thought out exception handling strategy, only about 5-10% of try blocks will have a catch , most are just used with finally (note that a using construct counts as a try/finally here). It wasn't me that originally said this, though I do agree - I believe it was Anders Heijsberg so it comes with good pedigree. There doesn't seem a lot of point in complicating the language for features that will rarely be used and which can be catered for in barely more verbose ways. IMHO anyway. If you include using blocks in the try/finally count this should definitely be true. Otherwise, I would suggest that if there are a lot of try/finally with no catches, IDisposable hasn't properly been designed into the application... Tag: Visual C# Language MAPI in C# ? Visual C#

However, since you have the "if (t1 is int)" section in there, it seems your attempt is pointless as well.

I am currently sending email from my C# windows application using System.Net.Mail by creating a SmtpClient.

However, I am being asked to use the Exchange Mail Server's "User names" instead of the actual email addresses. The SmtpClient method of sending mail does not seem to be able to do this.

I am told that another developer working with another language and development environment can do this. I asked him how and he said he uses MAPI.

Are there any built-in classes in DotNet for C# to use MAPI

My goal is to pass the mail server the user names instead of the actual email addresses.

Any help or direction is appreciated!

Re: Visual C# Language MAPI in C# ?

Thanks for the information.

Before posting I had run across this API in research of a resolution. After all is said and done, I guess this API is the most stable and simple to use. I was hoping that maybe Dotnet had some built-in classes but it looks as though I would need to reference the Outlook library which then requires a reference to a Microsoft Core Library. Seems too convoluted.

Anyway, thanks!

Another possible solution would be to use active directory to find the users email address. Personally I hate MAPI - had loads of issues with it, System.Mail.Net is they way I would go!
