Hello,
I have taken this code from somewhere i dont remember, and changed to work with doubles (since the int variable may not store the double variable)
double round(double Num, double Seed)
{
// get rational factor
double fac = Num / Seed;
// get natural factor
fac = (fac < 0) ? (ceil(fac - 0.5)) : (floor(fac + 0.5));
// fac = (fac < 0) ? static_cast<int>(fac-0.5) : static_cast<int>(fac+0.5);
// return multiple
return fac * Seed;
}
use it with round(3.8984, 0.01) for example....

hello
I use MFC in PPC to create a dialog to playback a video by direct show.
Because use direct show to playback, it will crate a video window view in toplevel.
But I wish the video is overlaped with the dialog and if some UI is showed in toplevel I can find by the message of the dialog.
Pls tell me how to solve the issue and thanks a lot.
Any suggestion is useful!! Thanks!!

I'm not sure I understand your question. Is the DirectShow window covering the dialog?
|
|
|
|
|
Yes. Use DirectShow will cover the dialog.
Any suggestion is useful!! Thanks!!

Assuming you are using one of the video mixing renderers (VMR-7 or VMR-9 then check this
out...
Using Windowless Mode[^]
Unfortunately, when using windowed mode, there's no interface to get the HWND for the window.
You can set its parent through the IVideoWindow interface but can't get its HWND to use as a
parent.
Anyway, windowless mode gives you much more flexibility/control.

hi,
i need to show a wait cursor while i'm savin on button click. i don't want to use CWaitCursor class. any other way?
|
|
|
|
|
You can use LoadCursor. But I would prefer CWaitCursor .
|
|
|
|
|
Well, why on earth do you want to do it the hard way ? Your other option is a try catch block that copies the code out of the CWaitCursor class.
In other words, the CWaitCursor encapulates the only way to create a wait cursor.

SetCursor(LoadCursor(NULL, IDC_WAIT));
and when you're done
SetCursor(LoadCursor(NULL, IDC_ARROW));

line_number : I can user __LINE__
date_time_stamp: This can be done.
user_string: This is also stright forward.
User_variables: How to do this? Can I user variable args? how?
how the interface should look like from DLL?
Please guide me to develope an independent component.

Hi,
I want to add some text to the begining of a existing text file while keping its
contents. I used SeekToBegin method but it overwrites the contents already in the
file. Is there a way to do that?
|
|
|
|
|
I presume you can't do that!
instead what u can do is open another temp file, and write the contents at the start of the temp file. and copy entire contents from the old file to temp file. After that replace old file by temp file.

Yes, But what if the contents of the old file is really large. Will that be a problem in efficiency?
|
|
|
|
|
u have to follow the same procedure even if the contents are very very large.
Because except Xenix, no other OS provide insertion of bytes in the middle of the file,
they support insertion only at the end of the file.

Open the file in different mode or flag

hi,
i need to place a bitmap on button along with the text on the button. i tried using CBitmapButton but don't get the text or rather the caption of the button. any suggestions???
|
|
|
|
|
I think you can only do that on toolbar control buttons, not on standard buttons.
You can make the text part of the bitmap though  May be a problem for a multi-language app
though.
|
|
|
|
|
isn't there a way to keep the caption of the button same and getting the bitmap in one corner of the button?
