Hello All,
I am changing the cursor position for inserting,updating and deleting the text in a text box control.
I am able to get the cursor position pertaining to the current cursor location though.
Please suggest me the way to find the text pertaining to the cursor.
Thanks and Regards.
Amar.

From VC++ Help:
<br />
CEditView::GetSelectedText <br />
void GetSelectedText( CString& strResult ) const;<br />
<br />
Parameters<br />
strResult: A reference to the CString object that is to receive the selected text.<br />
<br />
Remarks<br />
Call GetSelectedText to copy the selected text into a CString object, up to the end of the selection or the character preceding the first carriage-return character in the selection.<br />
A tip... Try checking the help. Go to index view, write the name of the control and at the bottom of the help text usually is "CLASS MEMBERS" link. With all the possible things you can do by default with that control/class.
Greetings.

Friends,
I wanted to know your suggestions on the following:
There is an MFC application with TCP/IP connections(CAsyncSocket) to connect to machines that send out a string when the user presses a button there.
Now what do you think is the probablity(Yes/No/%) that the string is not received by the software when they are connected on LAN??
Or
Is it that there is absolutely no chance of missing(I dont think so though)
Assumptions:
Physical connections, cabling are proper and never break.

The target machine will either receive the data or it won't.

There's always the possibility that the target machine could not receive the data.

is there any diffrence working on windows 2000 and windows NT.
|
|
|
|

There are differences of course.
But for instance, there are more differences between Windows 2000 and Linux (i.e. IMHO you have to reformulate a bit your rather vague question).
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

ya i am aware of ht differences between Linux and windows 2000
i am working on Visual Studio 6.0. now i want to know what differnce does it make working on 2000 and NT. i hope u got the question.
and what is this IMHO?

Well, usually, unless you're doing low level stuff, the differences are not so important. Anyway, for instance, compatibility of Win32 API is well documented for every function (under Requirements section).

Hi,
I am the administrator for my system.I have created a user.
What I need is , Can I deny the user from creating files and folders in my system?
If so, how can that be done programmatically?
Any suggestions would be appreciated.
Thanks

Hello everyone,
I am feeling template function is more tricky than template class. For the reason that the compiler will do the matching automatically for template function, but for template class, developer can assign how to match.
Sometimes compiler is doing mysterious matching rules for template function, which makes us confused. Does anyone have the same senses?
Example,
1. for template function
we define
template <class T> void sort ( vector <T>& )
when we invoke like,
sort ( vector<int> )&, T will automatically matched by compiler to int -- we have no control. Sometimes, how compiler will do the matching is mysterious.
2. for template class
developer has full control. For example, when use some template class, developer can assign the type of parameter,
we define,
template <class T> class Foo
{
}
when developer use it, we can explicitly assign the type, like Foo <int> or Foo <bool>.
Any comments or experiences or even disagreement is welcome.
thanks in advance,
George

And.... where is the problem? You are giving a < int > what do you expect? To have a double?
I dont really understand where the problem is..

And you can do a conversion of type in the first lines of the function as well, don't you?

Sorry Nelek,
I have not made myself fully understood. My question is (after reorganization),
1. for template function, we can choose to use either implicit mode to let compiler deduce or explicit mode to assign type;
2. for template class, we have to use explicit mode to assign type?
regards,
George

IMHO:
George_George wrote: sort ( vector<int> )&
The above doesn't make sense.
In both cases, the developer is providing explicitely the template type.

I suppose that you were asking about something like this (in which case your example is very badly chosen because you specify explicitely the type):
template <class T>
void myTemplateFunc(T arg)
{
}
And to use it, you do something like this:
int myValue = 42;
myTemplateFunc(myValue);
But, in fact even in that case there is no matching involved. The compiler will simply 'generate'a new function and replace T by an integer. Now if you call that function and supply a float, then the compiler will generate a second function and replace T by a float. You have to look at templates as code that will be generated by the compiler once you use the template (be it a class or a function). And if you call your function with two different types, then two different functions will be generated.
The only case where a matching is done, is when you use template specialization (if I provide a version of my function specifically for float for example). In that case, the compiler will try to find the best match. But in general, the compiler is quite intelligent to solve the problem on its own.

Thanks Cédric,
You understand my question well. My question is,
1. for template function, we can choose to use either implicit mode to let compiler deduce or explicit mode to assign type;
2. for template class, we have to use explicit mode to assign type?
