Remember what I said about "once you start using TCHAR"? All constant strings should be treated as TCHAR too, which means you wrap them in _TEXT() or _T() macros. (It is good practice to always use this macro, and use the corresponsing TCHAR-based versions of all string manipulation/processing functions. It takes a little while to get used to but quickly becomes second nature.)
That macro leaves the string unmodified in ANSI builds, or prepends the L modifier in Unicode builds, which converts it to a wide string, so...
<br />
m_display.Format( _T( "%f" ), output);<br />
-Becomes:
<br />
m_display.Format( L"%f", output);<br />
Peace!

James, you just solved another problem.
Regarding the TCHAR, I am using it only once for pwsstop.
I guess I don't need to be worried.
Thanks again James. If I come across any more probs, I'll email you.
Hope u dont mind.
thanx thanx thanx!

Hi folks,
here's the problem:
I have an internet-explorer-control in a dialog to retrieve a webpage. What I want is getting the webpage as a bitmap snapshot into the clipboard an then paste this into another document (in that case a MS Office Imaging file - tiff or mdi). Maybe, there are some other ideas to get the content of the webpage into the document (w/o usage of clipboard)?
With this document I do some OCR (with MS Modi-Component included in MS Office 2003).
Are there any ideas, code snippets etc. to do this job?
TIA

Hi..
I have a problem with line that I draw using mouse click (LButtonDown). I use VC++ and MFC.
The problem is whenever I maximize or minimize the window the lines that I draw dissapear.
Below is my code for LButtonDown :
struct LINE
{
int xp[2];
int yp[2];
};
LINE L[100];
int Lnum = 0;
int icoord = 0;
int isline =0;
int psize = 1;
if(bLineFlag)
{
CPen penRed(PS_SOLID,1,RGB(250,0,0));
CPen *pOldPen = NULL;
pOldPen = pDC->SelectObject(&penRed);
CRect rcClient;
GetClientRect(&rcClient);
CPoint xpoint,ypoint;
L[Lnum].xp[icoord] = point.x / psize;
L[Lnum].yp[icoord] = point.y / psize;
if(icoord ==0)
{
icoord++;
isline = 0;
}
else
{
isline =1;
pDC->MoveTo(L[Lnum].xp[0],L[Lnum].yp[0]);
t.x = L[Lnum].xp[0];
t.y = L[Lnum].yp[0];
pDC->LineTo(L[Lnum].xp[1],L[Lnum].yp[1]);
p.x = L[Lnum].xp[1];
p.y = L[Lnum].yp[1];
icoord =0;
}
DrawCross(point,RGB(0,255,0),5,pDC->m_hDC);
}
Could anyone help me with the problem..

You need to store your lines in memory (just the points coordinates) and then redraw everyting when the window is repainted. You will need to add the code for redrawing in OnDraw function

Hi cedric moonen..
thank you for your reply..so what's you saying is i have to transfer my coordinates from Lbuttondown to OnDraw?
I'm a newbie with MFC so the windows is repainted at the OnDraw function?
please reply thank you!!

What you can do is on the LButtonDown event, take the coordinates of the lines and store them somewhere (in your view or doc, I think document is better because it is designed for containing the data). Then invalidate the view (I think by calling Invalidate but not sure anymore), this will force your window to be redrawn (and will call OnDraw). Then in the OnDraw function, you draw all the lines that you have stored.
But there is an example of exactly the same case in the MSDN I think. This is called the scribble example (but I'm not sure)...

Hello All!
Have a problem with changing font color in static. I do like this:
<br />
LRESULT CPage::OnHandleAll(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)<br />
{<br />
if ((uMsg == WM_CTLCOLORSTATIC) && (HWND)lParam == GetDlgItem (IDC_STATIC_TEXT_ABONENT_TYPE))<br />
{<br />
ModifyStyle( 0, SS_NOTIFY );<br />
HBRUSH hBr = NULL;<br />
HDC hDC = (HDC)wParam;<br />
SelectObject( hDC, GetFont() );
SetTextColor( hDC, RGB(255,255,0));<br />
SetBkMode( hDC, TRANSPARENT );<br />
hBr = (HBRUSH)GetStockObject( HOLLOW_BRUSH );<br />
return (LRESULT)hBr;<br />
}<br />
}<br />
But color not changing in IDC_STATIC_TEXT_ABONENT_TYPE =(

Shouldn't you be doing this in the OnCtlColor() method. See MSDN article Q115087 for an example.

hiho@ll
i try to do a statistic prog, for host load
the problem is, i want this prog to be very generic, to use it for as many statistics data as possible
this means, there can be about 10 lines in my statistics diagram
my problem is, that i have a very poor algorithm for choosing the right color for the lines
anyone has an idea how the algorigthm for the linecolor would be, if i only know a linenumber
and i want the colors be very strong
my algorithm tends to use very bright colors, which isn't really nice to look at
it also would be nice if i could tell the function, if the linecolor should be bright or dark for a less or more interesting statistic lines
the color values i could use are standard RGB (0-255) values and an alpha value (0-127)
anybody has an idea?
thx@ll

Nehathoma,

Someone posted working string to double code before, then deleted the post, I guess they realised their question was non-existant.
This code requires you to include cstdlib.
char *stop = 0;
char * testvar="123.4";
double x=strtod(testvar, &stop);
What do you mean by string to ASCII ?

Hi All,
I have an application which uses automation to prepare a Word Document....
When i am placing the text i want to obtain the width that it would occupy with the selected Font and Size...
I have tried using GetTextExtent but the value that i get seems to be incorrect (thats visible from the output i get).
I have the Font size in points and the required width in Twips ....
So please suggest how can i achieve this by using a self created DC, i do ot want to depend on any Window ( my app is console based )..
Thanks and Regards,
ashwinder

You are on the right track but without seeing exactly how you are doing it, it's hard to say.

How are you verifying the results?

Hello,
I am working with VC++ 6.0 (MFC).
Normally an ActiveX control is binding with an application
exe) dynamically. We need to ship the "ocx" file with the "exe" file, for distribution.
My question is :
Is there any way to bind the "ocx" statically with the "exe" so that I can distribute the "exe" alone?
TIA,
Regards,
Jahfer V P

AFAMK to avoid the OCX file and get its functionality in your application, you will have to get the source code from the OCX vendor and include in you project. But this also may not be possible if the ocx and ur application are developed in different languages.
