And Why so:
LPTSTR-An LPWSTR if UNICODE is defined, an LPSTR otherwise.
Did you try using the code that I gave.

Somethings seem HARD to do, until we know how to do them.

Yes...If unicode is not defined then ur code is ok. Smile | :)

but wen unicode is defined then it will cause error. D'Oh! | :doh:

and one more thing
you need to mention that, call delete of str at the end. Unsure | :~

Thanks for your comment.
But just have a look at your post Sigh | :sigh:

. Shouldn't it be:
CString str;
m_editBox.GetWindowText(str);
No personnel issues but just to....... Big Grin | :-D

say that we don't post the code here that is always optimized.

Map it to some variable (ex: m_edit)
While mapping it select long as its type.
In the code use the following lines
long val;
UpdateData();
val=m_edit

CString csText;
GetDlgItemText( IDC_EDIT1, csText );// here IDC_EDIT1 is the id of the edit control

if StaticCtrl is an object of CStatic, then StaticCtrl.m_hWnd points to the handle to that static control.

Err... You don't need its handle. Just call the MoveWindow function directly:

pStaticCtrl->MoveWindow(...);

see i will tell u, there are many CStatic objects on the client window, right. Now what happens is that the user clicks on one of them and i get the address of that object in the 'this' pointer. Now i want to move this object according to the mouse drag on the screen, with the help of SetWindow Pos func and Invalidate(TRUE); I have the address of the CStatic object which the user is trying to drag.How do i get the handle of this object so that i can move it. is there any way to find out the handle with the help of this pointer.
otherwise tell me how i can move the CStatic window along with the mouse.

tab control

Hi all,

I'm writing an application to model the effects of
different volcanic sources. For every source i put in a dialog box
a combo box to select the kind of source and all the control to set the parameters
of every kind of source. Selecting the kind of source in the combo box only
the meaningful controls for that kind of source are enabled.

Acting like that my dialog box takes too much space on the screen,
so i need to split the different kinds of source in a tab control.
Can i do that without rewriting too much code ?
Is there a way to know which tab is selected ?
Sorry for the question but i'm a newbie.

Thanx in advance,
Demsmo16.

Hi,

You should think about using CPropertyPage and CPropertySheets. Converting from existing dialog resources is quite simple, and theres a good article regarding this on MSDN called Converting Large Dialogs into Property Sheets. Just search for that in Yahoo and you will find the article.

Good Luck Smile | :)

you have to read the original file, create a new one, and write inside it what you copied from 1st file....

the functions you can use are fopen(), fread(), fscanf(), fwrite(), fprintf(), fclose()...

also, see fstream if you have any chance to code in C++...
