Hi Anitha,
You can use this code:
void
CSplit::Split(CString str, CString separator, CStringArray& array)
{
CString aux;
int pos;
pos = 0;
array.RemoveAll();
for (int i=0; i<str.getlength();> {
if (str[i]==separator)
{
aux = str.Mid(pos,(i-pos));
pos = i+1;
array.Add(aux);
}
}
aux = str.Mid(pos,str.GetLength()-pos);
array.Add(aux);
}
Regards,
Gustavo

Hello.
I can use CClientDC and its TextOut function in C~~View class.
It's quite simple like this:
void C~~View::OnLButtonDown(UINT nFlags, CPoint point)
{
CClientDC dc(this);
dc.TextOut(x, y, "..");
}
Yet when I use this function in my 'added' class, which is not derived class of CView,
an error occurs.
like this:
void CMyclass::memfunc()
{
CClientDC dc(this);
dc.TextOut(x, y, "..");
}
So I changed the code like this:
[C~~View.cpp]
void C~~View::OnLButtonDown(UINT nFlags, CPoint point)
{
CClientDC dc(this);
CMyclass myclass;
myclass.memfunc(dc);
}
[CMyclass.cpp]
void CMyclass::memfunc(CClientDC dc)
{
dc.TextOut(x, y, "..");
}
And errors still occur.
Of course, I linked the header file of my class to C~~View.cpp.
I want to display Text or Images on window with code in 'my class'.
Please give me advice or ideas. Thank you.
May the sky bring you a full measure of health and prosperity.

You should pass the device context by reference, i.e. change your function definition (remember to change the declaration too):
void CMyclass::memfunc(CClientDC & dc)
{
dc.TextOut(x, y, "..");
}

If you check the documentation you see that CClientDC's constructor[^] gets a CWnd (or derivate) pointer, my guess would be that your own class has nothing to do with CWnd. Explain a bit more what you want to do.

What I meant was :
In MFC single document, I want to show Text on main window. And I also want this function to be operated in my 'own' class(which is a derived class of CWnd), not in CView class.
Pallini's answer is the best solution to my question (how nice of him/her ). It works well.
And now I've found another solution.
void CMyclass::memfunc()
{
AfxGetApp()->m_pMainWnd->GetDC()->TextOut(x, y, "..");
}
Thank you for your kind answer.
May the sky bring you a full measure of health and prosperity.

Hello
I make R&D virtual printer driver and I am using HP Color LaserJet 8500 PCL driver for
EMF spool file generation. It is not grayscale supported printer driver .SO when I print color
Document to black/ white use with color selection. But the EMF spool files in color.
If I convert EMF to BMP, the BMP size is as per as printer size 5000*4000 …so large. So it takes more time for image processing.
SO
Any one suggests how to convert direct color EMF file to black/ white or gray scale EMF file.
or
Suggest any grayscale, Color and Black/White also default EMF spool file generator Printer name.
Or
Any otherWay?
Thanks

Hi there.
Incase a stored precedure returns a set of records, then I can read the same by below code...
while(!recordset-> EndOfFile)
{
_variant_t var;
var = recordset->Fields->GetItem(L"TestName")->GetValue();
var = recordset->Fields->GetItem(L"TestID")->GetValue();
recordset->MoveNext();
}
Now, incase a stored precedure retunrs only a single value, lets say a hardcoded value "100", then how can I get that.
My main problem is, I am not aware of the column type, so how to read this returned value? please suggest.
Thanks
PanB

Well, you may check the variant type, usign its vt member. But would it be of any usage (if we esclude mere reporting)?

I am not able to get any relevent info.
Lets say my stored precedure is...
Create Procedure usp_ReturnSingleValue
AS
DECLARE @ReturnValue INT
SET @ReturnValue = 100
Select @ReturnValue
go
Now I want to read the returned value i.e., 100 from my c++ code.
|
|
|
|

Got it.
One need not pass any column name...
var = recordset->Fields->GetItem(L"")->GetValue();
Thanks Buddy for your help.

Hello,
I have to customize a old project to work with Cyrillic Characters. I have the following code:
CString MyText;
TCHAR buf[512];
SendMessage(lCurHwnd,WM_GETTEXT,sizeof(buf)/sizeof(TCHAR),(LPARAM)(void*)buf);
MyText.Format("%s",buf);
If the buf contains Cyrillic Characters (like Привет) this will be replaced with ??????.
Do you know a way to solve this problem? This is my first meeting  with Cyrillic Characters in a project and I do not know how to correct it.
I am using Windows XP, SP2, Visual Studio in English.
Thank you!

I'm not wading through all that!
But I can imagine the problem. The wizard needs to calculate the size of the dialog before creation, so it can create itself first, large enough for your ends.
Reading the PROPSHEETPAGE structure, it has a PSP_PREMATURE flag. That implies that the normal behaviour is to wait until the correct tab / next button is pressed before the page is corrected.
I can see two choices:
1) Use the PSP_PREMATURE flag, and hope that makes the calculations work on the actual window, rather than reading the dialog template.
2) Load the resource into R/W ram, change the font field, and use the PSP_DLGINDIRECT flag of the PROPSHEEYPAGE. Not an easy choice...
Good luck,
Iain.

I want to use CToolBar in a doc/view based project. when i set corresponding images for the toolbar, i found that the height of the bottons is not as high as the toolbar. so, how to make them as high as its parent(ToolBar)?
If i implement it by ownerdraw, i fond, there would be more issues to deal.
Any ideas?

I noticed that there are some differences between MS C++ and C++ that is used elsewhere, for example most tutorials available on the internet are in "normal" C++.
Are the commands so differnt that you need to learn one or the other or are they similar enough that if you leanr one, you know both?
I'm currently stuck in a class about MS C++ nad I don't have any poosibility to learn the "normal" C++.
When I'm done (3 months) will I also be able to programm with the "normal" C++ or would I have to learn that again?
If so, how long would it take (realistically) to switch from MS C++ to the "normal" one?
Thanks in advance.

Microsoft simply provides certain extensions to the C++ standard.
These extensions are MS specific and will work only with MS compilers and OSs.
Don't worry about learning one over the other. They're almost the same.
