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 ?

Can you help me

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).

And tomorrow we'll do the advanced course - which character will final contain after the statement? Roll eyes | :rolleyes:

Not to mention there's no sanity in converting any kind of a string to a character.

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 | :)

Usually you haven't. CString is a sequence of chars.
What do you exactly need to do (i.e. Be detailed)?

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.

I have commented the code inside the OnHScroll.But still it is showing the same result.

Hi Stuart

Thanks for the repling me.
The nPos parameter of the OnHscrol can handle only 16 bit data.
So when nPos is greater than 32677 it resets to 0.Thats why it was going to the initial posistion.
Using GetScrollInfo function it can be made into 32 bit data.
