How can I retrieve text from a static text control
that has wrapped the text , I want to get the
text with the line breaks that the control added ,
or I would like to know the number of lines
the wrapped text is printed on . I would also
want to know what text is not displayed because
it has "overflowed" off the viewing area .
Thanks for reading this .

I don't see any way to get this info from a static control. The wrapping is probably done
at the time the text is rendered.
You could parse the text yourself and calculate wrap positions using GetTextExtentExPoint()
and render the text youself.

The same methods you'd use to do this in any window should apply...
For the window itself, you can specify a brush when registering the window class or handle the
WM_ERASEBKGND message and draw the background yourself. To do this, derive a class from the
window class in the article and either register a custom class for the window or add a
WM_ERASEBKGND handler.
For buttons, you'll need to owner-draw them.

Hi,
CTcxMsgBox class is derived from CDialog so there is no WM_ERASEBKGND messsage to add the message handler.How to add a different background color for CDialog based class? There is no dialog resource associated for CTcxMsgBox class and it produces the MessageBox using the function
CDialog::InitModalIndirect( (LPCDLGTEMPLATE)_dlgData, m_pParentWnd );
When I put the function
SetDialogBkColor(RGB(206,207,206));
in the CWinApp derived application class's InitInstance() then MessageBox is being shown in new background color but buttons and CRichEditCtrl (which is for text message) are not shown in that color.
Now How to draw the Buttons in different background color?
best regards,
Cyber Friend

Hello !
I'm trying to have a CListCtrl having the same behwvior as in the task manager (when you list the active processes). I set the view to report (to have the different columns). But currently, I can only select a line by clicking on the items in the first column. I would like to be able to click anywhere in the list control and having the line under my cursor to be selected.
Any idea how I can do that ?
Thanks

How to declare a CALLBACK function by myself?
And how to make it called?
Can you please help me on this.

A callback is a function that you define but don't call yourself (thought nothing prevents you to do it). A callback is needed whenever you application has to perform some custom actions on occurrence of particular events. For instance, consider the Windows API EnumWindows (see here ^]), for each found window the OS calls the callback you defined (and as you may notice, you have to conform your callback declaration to EnumWindows requested one).
To summarize, usually:
(1) You have to declare you callback as requested by the callback caller.
(2) You may define your callback as you prefer.
(3) You don't call yourself the callback function.
of course the depicted scenario applies to most of the cases, on the other hand, if you are designing, for instance, a framework, then you have to apply the opposite point of view (i.e. establish the callback declaration, let the user application to define it, call the latter whenver appropriate).
Hope that helps.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

where f-is the first box generated and l-is the last box generated
void printinstance(item *f, item *l, itype W, itype H, itype D)
{ int p,Wcont,Hcont,Dcont;
int const max=1000;
item *i,*j;
itype x1, y1, z1,x2, y2, z2;
stype vol, totvol;
int notip,po;
Wcont=(int)(W);
Hcont=(int)(H);
Dcont=(int)(D);
for (i=f;i<=l;i++)
{
notip=1;
x1 = i->dx; y1 = i->dy; z1 = i->dz;
for (j=i+1;j<=l;j++)
{
if ((i->dx==j->dx)&&(i->dy==j->dy)&&(i->dz==j->dz)) notip++;
}
p=1;
for (j=f;j<i;j++)
if="" ((j-="">dx==i->dx)&&(j->dy==i->dy)&&(j->dz==i->dz))
{
p=0;
break;
}
if (p)
{
x1=i->dx;
y1=i->dy;
z1=i->dz;
XmlTextWriter^ writer = gcnew XmlTextWriter("d:\\contload.xml",Encoding::UTF8);
writer->Formatting = Formatting::Indented;
writer->Indentation=4;
writer->WriteStartDocument();
writer->WriteStartElement("ContainerSolution");
writer->WriteStartElement("ContainerDimensions");
writer->WriteAttributeString("ContainerWidth",W.ToString());
writer->WriteAttributeString("ContainerHeight",H.ToString());
writer->WriteAttributeString("ContainerDepth",D.ToString());
writer->WriteStartElement("Boxes");
writer->WriteAttributeString("BoxWidth",x1.ToString());
writer->WriteAttributeString("BoxHeight",y1.ToString());
writer->WriteAttributeString("BoxDepth",z1.ToString());
writer->WriteEndElement();
writer->WriteEndElement();
writer->WriteEndElement();
writer->WriteEndDocument();
writer->Close();}}}
and I call my function in the main program like this printinstance(f, l, W, H, D);

I tried to look through your code but because of HTML reformatting there's some stuff missing.
This is a short function - can't you step through with the debugger?
If it's only writing the last box then single stepping through one iteration should show you why
it's not writing.

Hello All,
I have a problem regarding file. I m trying to open a file using CStdioFile Object like this
test_ptr.Open(File_name,CFile::modeReadWrite,NULL);
i have checked using _access function that this file is present at the desired location or not
int a = _access(File_name,0);
_access is retruning 0 that means file is present but open function is not opening the file (it is also returning zero).
(i have also checked manually file is present at location)
what can be the problem for not opening the file
can anybody help me in this
thanks in advance
