I have following code:
CFileDialog fileDlg(TRUE, _T("*"), NULL, OFN_PATHMUSTEXIST | OFN_OVERWRITEPROMPT, _T("All files (*.*)|*.*||"), NULL);
if(IDOK == fileDlg.DoModal())
TRACE(">>>%s\n", fileDlg.GetFileName());
and when I select a file, no mater what kind of file, I get:
>>>D
that is all ... why ? What I have done wrong here ?

You are passing an ANSI string to the TRACE macro. Therefore, an ANSI string is expected for the %s parameter but you have a Unicode build and fileDlg.GetFileName() returns a wide string.
So you should use the _T() macro also for the TRACE argument:
TRACE(_T(">>>%s\n"), fileDlg.GetFileName());
See also the examples at MFC Debugging Techniques[^].

Thank you. That was the problem.

1. I set tab order for control in a MFC dialog.
2. Started the application.
3. Clicked a button in dialog, whose tab order is 3.
4. A modal dialog displayed.
5. Closed the modal dialog.
Now the focus automatically moved to the control having tab order 0.
Since the focus was on the button just before the click, I would like to retain the selection on the same button.

But did this button actually have the focus at this point?
|

Yes.
Before button click, even if the last focus is on another control( say tab order 2 ), after closing the Modal dialog the focus move to control having Tab order 0.

I have a similar application (Win32 rather than MFC), but the focus stays in the correct place on return from the second dialog. I can only suggest you do some debugging to try to see what is happening under the covers.

How are you verifying this?

Yes. I think the default MFC application created using the VS2010 wizard has this behavior.

There is a world of difference between thinking something and actually checking it. If this was the default behaviour it is likely that many programs would not work.

Nice quote 
Could you please suggest a solution!

Solution to what? We have no idea what your code is doing, or what you are doing when you run it, beyond your belief that the focus moves after you run some dialog. The only way to move forward with this is to write a very simple test program to demonstrate the problem and run some tests until you can isolate exactly what is happening.

The onus is on you to narrow the problem down to just the relevant code. Sane folks aren't going to chase links around and pull unrelated code from a project.

I did not done any specific code for the setting the focus. I just shared the framework generated code for easily reproducing the issue, so that you can understand the issue clearly.

I want to create an IDE which should have similar look and feel like Visual Studio itself.
For this I created a "Visual Studio Style" Project by usage of AppWizard.
Now I am wondering, how to implement "Windows Float" functionality?
What I mean exactely? e.g. when you look at Visual Studio's Solution Explorer window, there is a small down arrow in the title bar. When you click on it, a menue opens and you can change the window style to "float".
This feature I want to use instead of a non modal dialog, becaue this would be much more flexible.
Has anybody an idea, how to implement. Maybe it is also implement in the IDE Framework of the MFC, but I do not know how to activate??
Any ideas?
Many thanks

favorite I have seen CPU scheduling algorithms (Rate monolithic - Real time CPU scheduling) or priority scheduling using array data structure
http://c-programmingguide.blogspot.in/2012/09/c-program-for-rate-monotonic-scheduling.html
But I would like to know if this is the preferred data structure if yes why OR if any data struture is preferred for RMS then which one is better and why
any suggestions would be appreciated
Thanks in advance

Hello Everybody,
We have an application which is created in VC++ 6.0 version, in that we are displaying some colors (Pantone color) reading the colors from text file and displaying.
When I use the same text file (with same color details), in Visual Studio 2008 or higher, the application is displaying different color (actual color is this)
For example,
Original RGB is 198, 93, 82
Using color picker, for old application, its giving RGB as 120, 27, 20 and in the new application it shows 198, 93 and 82.
Will there be any color variation between old and new applications (visual studios)?
Thanks in advance,
A. Gopinath.

Howdy, I'm not so sure I understand your question.
rgb(198,93,82) looks like This , while rgb(120,27,20) looks like This
Obviously, these 2 colours are not only very different in terms of their RGB values and their HSL values for that matter, but they also appear very different to anyone not unfortunate enough to be hit with R-G colour blindness. Aren't you actually telling us yourself that the colours appear differently?
Their pantone numbers are also very different, 180 U vs 1815 C
I can't help but wondering 3 things:
1) What is the format of the input in the text-file and the exact input that produces these colours?
2) How is this being transformed into a colour by your application?
3) What difference did you find when you stepped through the conversion process in your debugger in each of the versions of the application?
I'm not familiar with the conversion process between rgb <--> pantone to know if a small difference in precision could produce such a wildly different result, or if it's an integer-only process that could suffer from a signed/unsigned error. Showing the input and the way it results in a final colour could well help, though it may not.

Hello,
Thanks for your reply.
This is the format in text file in which pantone color details are written.
PANTONE Number Name L* a* b* sR sG sB
PANTONE 11-0103 TCX Egret 93.74 1.19 6.78 243 236 224
PANTONE 11-0602 TCX Snow White 94.93 0.1 2.67 242 240 235
PANTONE 11-0601 TCX Bright White 96.21 -0.44 1.61 244 245 240
The value which I gave previously is
PANTONE 17-1544 TCX Burnt Sienna 53.75 43.63 28.62 198 93 82
In the new application, on a color button (CColorBtn), i am displaying the colors.
In the old application, they are loading this L, a and b values, converting into color values. for this, they are using some third party, i am not able to go depth in that. color is displayed on some other control, not on button in old application.
Regards,
A. Gopinath.
