I have found a few examples of how to use the richedit control 4.1 within an MFC app, but does anybody know how I can implement its usage in a non-mfc app?
I have a dialog with a rich edit control which contains a table. currently I'm using version 3 of the control which shows the table, but when it comes to populating cells I'm having problems. Mainly that the control doesn't seem to implement much of the table formating commands. The table cells do not resize, /par is ignored /qc is ignored etc...
I doubt my code is to blame as I am simply loading a rtf file created with version 4.1 and displaying it within my own control.

Nevr mind, I fixed it. For anybody else who may be trying to do the same:
In WinMain:
InitCommonControlsEx()
LoadLibrary( "Msftedit.dll" ); // check the return value
When creating the window:
CreateWindowEx(0,"RICHEDIT50W","",WS_TABSTOP ....
If you created the control using the resource editor, you must open the .rc file with a text editor and change the class from "RICHEDIT" to "RICHEDIT50W".
Point to note, the Msftedit.dll is not distributable, and it will only work with Windows XP service pack 1 and above.

Hi everyone. anyone knows how to create a trackbar in visual c++ using Win32 API?? I dont know what header file to include. Thanks in advance.

You need to include commctrl.h and link with comctl32.lib. You create a trackbar pretty much the same as any other control
InitCommonControls();
hwndTrack = CreateWindowEx(
0,
TRACKBAR_CLASS,
"Trackbar Control",
WS_CHILD | WS_VISIBLE |
TBS_AUTOTICKS | TBS_ENABLESELRANGE,
10, 10,
200, 30,
hwndDlg,
ID_TRACKBAR,
g_hinst,
NULL
);
You can find a wealt of information here[^] regarding track bars and how to use them.

I used MFC AppWizard->Selected Single Document Interface-> and all nexts then clicked ok at step six using Visual Studio 6.0.
I then put this following code in the OnDraw() function in FilenameView.cpp.
I didn't change any other codes than this.
void CWoosooView::OnDraw(CDC* pDC)
{
CWoosooDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
// TODO: add draw code for native data here
///////////////////////
// MY CODE STARTS HERE
///////////////////////
///////////////////////////////////////
// i tried to make a pointer and put in some numbers 0~255 to make a rectangle pyramid.
///////////////////////////////////////
int size;
unsigned char *p;
p = (unsigned char*)malloc(size*size);
for(int y = 0; y<size; y++)
{
="" for(int="" x="0;" x<size;x++)
{
="" if="" ((x="">=0 && x<(size/2))&&(y>=0 && y<(size/2)))
*(p+size*y+x) = (x+y);
else if ((x<size &&="" x="">=(size/2))&&(y>=0 && y<(size/2)))
*(p+size*y+x) = (size-x+y-1);
else if ((x>=0 && x<(size/2))&&(y<size &&="" y="">=(size/2)))
*(p+size*y+x) = (size+x-y-1);
else if ((x<size &&="" x="">=(size/2))&&(y<size &&="" y="">=(size/2)))
*(p+size*y+x) = (2*size-2-x-y);
}
}
////////////////////////////////////
CBitmap bitmap; // i made a bitmap
CDC memDC; // and a device context
memDC.CreateCompatibleDC(pDC);// then made it compatible
bitmap.CreateBitmap(size,size,1,8,p);//**************problem line
memDC.SelectObject(bitmap);// then let the device context select it.
pDC->StretchBlt(0,0,size,size,&memDC,0,0,size,size,SRCCOPY);// and displayed.
free(p);
}
///////////////////////
// MY CODE ENDS HERE
///////////////////////
}
***********problem line, which is ====> bitmap.CreateBitmap(size,size,1,8,p);
// here's the problem. when i change the 4th value 8 to 1, a monochrome pyramid appears when executed. but i'm trying to make the pyramid smoother just like the greyscale. so 8 should be left 8, i think....
Right now, nothing appears on screen.
someone plz helpme~~

Is there a "trick" to get the next biggest power of two for a given value?
I wonder if there's something without a loop (or a binary search).
I know the N & (N-1) == 0 <==> N is a power of two trick, but that doesn't help me much finding something.

Wow!
thanks - I just had the entire dev team come to a screeching halt after asking the question...

So this question did cost your company several million dollars?!?

Another solution would be:
int iNextPower2 = 0;<br />
double x;
<br />
iNextPower2 = (int)((log10(x)/log10(2) + 0.5)
This works for raising any base to a power... number of significant digits for an octal number representation of a decimal number would be:
<br />
iPower = (int)((log10(decimalvalue)/log10(8) + 0.5)
Hope that helps.

A much slower solution (in terms of CPU cycles), it should be noted.

yep, that's the "natural" solution, but much to expensive. Thanks anyway

Sorry, I must have missed where you indicated it must have a very low cost in cpu cycles.
I was just giving a generic solution without loops like I believed you were looking for.

[EDIT]
Whoops, never mind.
Reread your question and realized you want to find where FkGrainUp2(S, G) == G.
[/EDIT]
FkGrain*N() - round S up/down to nearest multiple of G
FkGrain*2() - round S up/down to nearest multiple of G, where G must be a power of 2
Will work for all unsigned int types, not just unsigned long long.
ullong FkGrainDnN( ullong S, ullong G )
{
S = S - (S % G);
return(S);
}
ullong FkGrainUpN( ullong S, ullong G )
{
ullong r = S % G;
if( r ) S = S + G - r;
return(S);
}
ullong FkGrainDn2( ullong S, ullong G )
{
S = S & ~(G-1);
return(S);
}
ullong FkGrainUp2( ullong S, ullong G )
{
G -= 1;
S = (S+G) & ~G;
return(S);
}

Hi everybody :- ). Long time no postin'. I worked in other areas lately but now I'm back in C++ at a problem left unsolved some time ago. The problem is quite severe as in I am lacking some very important information (which apparently I can't find in MSDN). You see... I want to create a window which has a control box, minimize and close buttons and a thick frame, but NO RESIZE. So far, I used this:
hwndThis = CreateWindowEx //Creating the window.
(
NULL, //ExStyles.
sClassName, //Class name. Created somewhere above.
Title, //Window name.
WS_OVERLAPPEDWINDOW &~ WS_THICKFRAME &~ WS_MAXIMIZEBOX, //Styles.
X, //X.
Y, //Y.
W, //Width.
H, //Height.
NULL, //Parent.
NULL, //Menu.
hHost, //Parent.
NULL //CreateStruct.
);
As you can probably already guess, this does the job, but creates a window with a very thin border and I don't like that. If I remove WS_THICKFRAME, of course, it works but then I can resize it again. Soooooooooo? Any ideas anybody? :- ). Thank you in advance!

You can handle the WM_SIZING message and simply modify the rect to the app size.
onwards and upwards...

Not good because I will still see that annoying arrow-resize icon. There has to be another way. A style or something. Something I missed in the MSDN documentation.
