Re: when to use switch-case and when to use if-else

Although you are satified with all answers i want to mangle in the discussion. To my opinion If and Case are very different because:

If <condition>

and

Case <constant>

where <condition> is ANY expression that results in true or false, while the Case can only be a constant (from the same datatype as the variable named in the switch). As you see possible values of a variable as a domain then a Case construct is more like a domain-checker...

There are many if constructs that can not be rewritten to a Case construct. But all Case constructs can be rewritten to If-constructs, although performance can/will be worse. See the Case construct of a specialized version of If, losing some flexibility but gaining some performance...

Generating "msoult.h" from "msoutl.olb" using VS2005

Hi.

I'm trying to write a program that automates outlook 2007 using c++. Found some samples, all requires "MSOUTL.H".
How do I generate "MSOUTL.H" from my "MSOUTL.OLB"? I'm using VS2005 and Outlook 2007.

Can I make a suggestion - rather than using whatever you are using to try and automate Outlook, use #import to do automation in C++ - it's the simplest and easiest way. Here's how I automate Excel 2007 (getting the active workbook name in this case) - automating Outlook just requires you to determine Outlook's libid (which, from the OLE COM object viewer, is 00062FFF-0000-0000-C000-000000000046):

#include <iostream>
#include <Windows.h>
#import "libid:00020813-0000-0000-C000-000000000046" version("1.6") auto_search no_dual_interfaces rename("DialogBox", "excelDialogBox") rename("RGB", "excelRGB") rename("DocumentProperties", "excelDocumentProperties") rename("SearchPath", "excelSearchPath") rename("CopyFile", "excelCopyFile") rename("ReplaceText", "excelReplaceText")

int main()
{
   CoInitializeEx(0, COINIT_APARTMENTTHREADED);
   // Ensure the Excel::_ApplicationPtr is destructed before we uninitialize COM.
   {
      Excel::_ApplicationPtr xl;
      if (SUCCEEDED(xl.GetActiveObject(__uuidof(Excel::Application))))
      {
         std::cout << "Getting name\n";
         std::cout << xl->ActiveWorkbook->FullName << std::endl;
      }
   }
   CoUninitialize();
   return 0;
}

Why would you convert a string to a unique character ? Confused | :confused:

Or do you want to retrieve the first character of the string ?
Did you take a bit of time to think about the 'validity' of your question ?

Are you aware of the fact that a string is composed of multiple characters? And you're wanting to convert a string to a character. Doesn't this sound ridiculous?

Please do yourself a favour by reading an elementary book on C++ or rather start with C. You have a long way to go before you can post something meaningful here.

You want to make something that doesn't have any sense ?
Do you know what a character and what a character string are ? Why do you want to store an array of characters into a single character ? This doesn't make any sense at all. Do you want to use a char* instead ? If yes, as already told you a lot of times before, read the article that Rajesh suggested. Why do you keep asking the same type of questions again and again instead of trynig to understand the concept ?

Yes, but you'll need to do this instead:

final = test[0];

I'll leave you with the exercise of figuring out why final only contains one character (instead of 11).

So, we cannot help him, can we?

I see the OP has a LOT of reading to do, but if he won't, that would be the least of our interest (besides the fact that he posts the same stuff repeatedly and irritates). We can only suggest him what should he do.

Looks like a lost cause though. Smile | :)

Do you need the same email in both cases?
What is failing here and how are you validating the error?

Use IMessage::ModifyRecipients - I know that works, 'cause I've used it in the past.

You need to create an address list to pass to that. I've done that using the IAddrBook::ResolveName method to convert textual addresses to MAPI addresses. That part of it's kind of involved, but basically you construct a new ADRLIST with each recipient's name and a property specifying that you want a 'TO' address and pass that to ResolveName. This method should transform the address list into a list of resolved address entries.

HTH!

Problem while horizontal scroling

Hi all

I am facing a problem while horizontal scrolling.
My class is derived from CScrollView and i am displaying a graph in that class.

While i am dragging the scrollbar and when it reached in the middle, it is returning to the initial position.But there is no problem with scroll to absolute position.

Please help me

Thanks and regards
Deepu

It's more than likely that your OnHScroll handler's wrong, resetting the scroll bar position after dragging. But it's difficult to tell when you've provided so little information.
