Hi, I'm trying to modify and change and save a Visual C++ read-only file/project and I'm not sure how to go about doing this. The message I keep getting is:
"One or more od the source files (RemoteTestDlg.cpp) for class CRemoteTestDlg are read-only. Changes canot be made to read-only files!"
Please help. Thanks.

why on earth are your sources R/O, and why do you think you can modify a R/O file ?
remove the flag first in the file properties, then edit it

Here, any Files I forgot to check out of the source management system are read only.
And neither VS2003 nor VS2005 have any problems with unsetting the read-only flag on the fly: They ask, I click "Overwrite", and they overwrite without problem.
I have to be more alert when checking the files back in, but that's OK.

It works fine now. I was trying to modify a downloaded visual c++ 6.0 sample program to build another application. Thanks a lot.

VC++ 6?
Because VS2003 as well as VS 2005 ask whether to remove the write-protection.
Did you copy them from a CD? Some burn-progs make all files on CD write protected and theis gets copied with the fiels.
You can simply use the explorer to remove the read-only-flag.

I have a bitmap that is mainly black with some white pixels on it. This bitmap is updated continuously. I want to some how create an effect that can produce a sort of trail from the bitmaps using only GDI. An effect simerlar to what you see in wmp visualizations.
Any ideas?

Im in a C++ MFC visual studio 6.0 workspace. i have a float, which i need to round, both mathematically and string wise..
For example mathematically this;
0.306-> 0.31
0.99-> 1.00
and string wise;
0.12000000 -> 0.12
12.0000000 -> 12
Ive surfed around, but only found ones that dont remove unnecessary zeros, and dont work perfectly for all numbers..
The variable i have is a float, and im guessing its atof thats creating the extra zeros (which i have to use, or something equivalent)
rounding should be to 2dp, ie allways x.xx
any ideas?
thanks!

This is
int integer = (int)(0.306 + 0.5);

Maybe boosts format library[^] can help you?

this is a matter of representation, so basically, printf() does it !
for the 2 questions btw, you can have a look here[^]

There's also the ceil() and floor() functions. It's really just a matter of trying each suggestion until you find the one that does just what you need.

Strings:
CString str;<br />
float f = 0.306;<br />
str.Format(_T("%.2g"), f);<br />
TRACE(_T("%s\n"), str);
Because I've used %g (instead of %f), 12.0 will be 12.
Numerics:

Well, that's not very "generic" (what happens when you need to round at a higher precision?).
double Rounder(double fVal, int nPrecision)
{
nPrecision = __max(__min(16, nPrecision), 1);
double fEpsilon = pow(10, nPrecision);
double fResult = ( floor(fVal * fEpsilon + 0.5) / fEpsilon);
}

Now, that seems good, but it does lots of weird things that i dont want, try setting f to, 299.99 or 31.2699
thanks!!

that's normal floating point behavior...

I have an SDI style (no doc/view) MFC application that has several windows. These the content of these windows take a while to initialise and the net result is that from double clicking the icon to the application apearing takes a long time and makes it apear that it has not been started.
I would like the main ui of this application to appear asap and then initialise the processes that take time to get going.
Anyone have suggestions how I might be able to achieve this?

You can start the task once the dialog is showing. You can use a thread that would keep on downloading and updating the controls and the data that you need to show in your application, also you can show a progress bar somewhere on the screen of your application that some work is in progress and the user needs to wait until he can work on the application.
Somethings seem HARD to do, until we know how to do them.

My app isn't dialog based! But I assume the technique would be the same for a dialog app and Windowed app. Would I start off my thread from OnShowWindow or OnActivate? (with traps to ensure it dosent get fired more than once)

So what are you having the application do?

I havent got to the point of working out what is taking up the time but I thint it might have somting to do with the 2 http (aspx) server (one used by the application only and the other for external access only) and displaying of a video file.
These are things I want to delay the start up/initialization of.

So don't start these things until after the application has fully shown itself.

This is exactly what I want to do hence the original post...
When do I know when the application has fully shown itself?

That's hard to say since you've removed the doc/view support from it. Do you still have a "main" frame? Has anything replaced the view?

I do still have a Main frame. The main frame contains a CChildView and this is where all the other visible elements are contained. CChildView inherits CWnd.
