Hi all,
I use the edit control EN_CHANGE event in order to update a slider in a software.
The edit control contains a number. My problem is that every time i write a digit in
the edit control this triggers the EN_CHANGE event, the slider is updated and the cursor
in the edit control is put at the beginning. I wanna the update of the slider
AFTER i enter the whole number in the edit control, not for every digit, but my
boss want me to do that without using a button to load the value entered in the edit control
into the slider. Is there another event i can use to obtain that ?
Thanx in advance,
Desmo16.

what is a whole number ?
I know what it is, but what is the difference between 23 and 234 if both values are valid ?
you could handle the kill focus event to only update the slider when the focus change, or handle the enter key and update the slider when the user hit the enter/return key.

When i say "whole number" i mean "not a single digit",
that is to say 345 or 765 and not 1 or 5 or 9.
And no, not all values are valid 'cause they had a geophysical meaning in the software.
Anyway, how can i trigger the event handling the enter key ?
Thanx in advance,
Desmo16.

Your use of 'whole number' makes no sense. I presume you mean a number that's been completely entered.
There is no event that's fired only when the text is a certain length, you'd have to check that yourself in the EN_CHANGE event, and update the slider only when it's within the range you're hoping for.

So why not just add the "hidden" attribute to each file/folder?

I want to use Domodal() function call child windows, and also want parent windows can click during child windows appear.
How I write the code.

You can't. Either you show a non modal dialog, or it's modal ( which means that the parent windows don't respond while the window is up.
To make a non modal dialog, it needs to be a member variable.

You'll need to create a modeless dialog for this.

Hi all,
Ok so I know this is a VC++/MFC forum, but I was wondering if someone could please help me in linking / using a dll in Borland C++ 6.
Thank you in advance
The only programmers that are better than C programmers are those who code in 1's and 0's.....

I haven't used borland in a while, but if memory serves me correct, it spits out a .lib file when you build the dll. You just need to add that file to the link line in the project properties.

If you don't have the lib file as Zac suggested, check out the IMPLIB.exe and IMPDEF.exe utilities.
They can generate the files you need to link.

I am getting this error message when I am trying to create a Dialog Procedure and make it member of a class so I can use ‘this’ pointer of that class.
“error C2440: 'type cast' : cannot convert from 'overloaded-function' to 'DLGPROC'”
Please help me to solve this problem. Thanks in advance.

Are you using MFC?

Normally you cannot do this. The easiest way is to declare the DlgProc as a static member, but that will give you problems accessing other class members. You can also store the this pointer in a static member, and again add a static DlgProc then cast the pointer to access the class members, but this method causes problems when using more than one instance of the class. By far, the best method is to use a thunk.

I believe you are trying to make a wrapper class for handling dialog without using MFC ? If this is the case, there is a trick to do that. If not, then ignore my post 
Ok, so member functions and global functions don't have the same parameters (the this parameter is passed to a member function). That's why you are getting this error. However there is a trick to do what you are looking for. I'm a little bit lazy to explain all in detail so I made a search on google, and I found this[^] piece of code that solve your problem. If you don't understand some parts, just ask.
Basically the idea is that you save the pointer to your class instance with SetWindowLong as user data and you get it back in your dialog procedure, so that you can cast it back to your class (and so, call a member function that will manage the messages).
Hope this helps

Thanks for your reply,
I tried that code. But now I get another error. "error C3861: 'Dialog': identifier not found, even with argument-dependent lookup" at at line "Dialog* pthis = (Dialog *)GetWindowLong( hWnd, GWL_USERDATA );"
maybe because that code is in MFC while I am using win32. Can I know how can I use the same with win32?
