If its a simple text file using CEditView will do, try creating simple SDI application and choose baseclass as CEditView in last step of app wizard.

Befor I do something like this ..

CString input;<br />
// assign something to input<br />
sprintf_s(buf, 16, "%d", input);

I'd like to know whether the input is a number, but how ?

Well, sorry ...
The var input is a CString

I'd like to print an error if someone submits an alpha instead of a numeric input.

Use CRT function isdigit.
But, again this will work for single character.

BOOL Flag = TRUE;
int length = input.GetLength();
for(int x = 0; X < length; x++)
{
if(!IsDigit(input.GetAt(x)))
{
Flag = FALSE;
break;
}
}
if(Flag)
{
// input is numeric
}
else
{
// input isn't numeric
}

if you need to check if input is a number (integer or float) the following code will work

BOOL Flag = TRUE;
int length = input.GetLength();
for(int x = 0; X < length; x++)
{
if(!IsDigit(input.GetAt(x)))
{
if(input.GetAt(x) == '.'
continue;
Flag = FALSE;
break;
}
}
if(Flag)
{
// input is numeric
}
else
{
// input isn't numeric
}

Parent Window decision

prithaa7-Mar-07 21:34

Hello,

I have a class derived from CMDIChildWnd like this

class Wind : public CMDIChildWnd
{
View1 m_View1;
}

class View1 : public CScrollView , public MyView
{
CRichEditCtrl* cedit;
}

Now when I create the objects of the above classes in each of the create I need to give the parent frame. so in this case

CMainFrame* pFrame = STATIC_DOWNCAST(CMainFrame, AfxGetApp()->m_pMainWnd);

Wind WindObj* = new Wind;
Wind->Create(NULL, "FrameName",WS_VISIBLE ,
CRect(0, 0, 0, 0), pFrame, NULL);

View1 View1Obj* = new View1;
CScrollView::Create( NULL,NULL,AFX_WS_DEFAULT_VIEW,
CRect(0, 0, 0, 0), WindObj, NULL);

CRichEditCtrl* cedit = new CRichEditCtrl;
cedit->Create(WS_CHILD|WS_VISIBLE, CRect(10,10,50, 50), View1Obj, 1);

But cedit doesn't work with View1Obj.Instead if I provide the parent to Wind the CRichEdit Box is created.

I thought that the CRichEditCtrl box is made on the View so View pointer can be the parent then how come CMDIChildWnd is the parent of CRichEditBox.

Any clues how a parent is to be decided?

Thanks a lot. I am interested if there is an easier way to do it -> I build a separate version for Japanese language so I do not need multi language support. Just starting a simple MFC Dialog application on which I can add static texts in Japanese.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
