i typically see that when the breakpoint was set in a module which wasn't built in debug mode (or didn't have debug info)
|
|
|
|
|
I don't think this was my case. I have been compiling and debugging just fine when it just started happening.
Then it went away! I suspect it may have something to do with running a timer because it give me this error when I was setting the breakpoints in OnTimer function / method. It started working again, but I had other problems when keeping the timer running during debugging so I immediately killed it in OnTimer. When I have a break I’ll try to make it happen again.
Thanks for you help.

What is the difference between messages starting with WM_ and NM_ ?
Why there are two set of messages for the single (right click)event like:
1. WM_RBUTTONUP
2. WM_NOTIFY NM_RCLICK
Are they completely different?
Regards,

NM is for Notification Messages sent from Window controls to their parent window, where as WM are Windows Messages.

Does anyone have any good ideas how to identifiy which CD is in the drive?
I'd like to do this without reading too much of the drive, i.e. should be fast!
I am using GetVolumeInformation to identify drives. Drives usually have a serial numbers, but many CD's do not.
When the CD or other volume is online, I'd like to gather identifying information about the device -- something unique -- like a serial number.
And later, would like to check if the device at that drive is the same one as I identified before.
This way I can tell whether the volume I thought was there -- is still there.
Any clues for me on how to proceed?

You can try computing HD5 hash of 4-5 files in the CD and also store their path. Then everytime a CD is inserted you check if files you checked last time are present on CD and if their MD5 hases are identical. You may also compute a single unique number by combining file names and file data information. So that comparison is easy.

Sample code would be great, thanks very much.

You don't do anything special.
You expose method with parameters like you would for any ActiveX COM interface.
The user will usually have a script section in the html that instantiates your control, calls the methods, and passes in whatever parameters needed.
Now there is the issue of whether your ActiveX control is "safe for scripting" since you are subject to browser security etc...

hi
is it possible to compile c code to Visual C++.Net dll ?
and how can we do it in case it is possible !
Thanks
|

Its actually very simple, you just use the /clr compiler switch, and the NET Framework compiler will compile the application as managed code.
This probably isn't a good idea, though, for various reasons.
Read this over at MSDN: /clr Restrictions[^]
You should probably start here: How To Migrate to /clr[^]
And, Native and .NET Interoperability[^] provides an overview of the subject

I don't think you can compile C code using the /clr
compiler option.
You can create a C++/CLI project and include C files in it,
but only C++ code will be compilable managed (the C++ code can
call C code).

If you try to compile c code for make a c++.net dll you will be get some errors I think you need to change some things on your code.

Using Visual C++ 6.0 MFC in SDI application
When my window gets redrawn, I want to display a message using
pDC->TextOut(...)
but I want a different message (of different length) displayed depending on the circumstances when the window gets redrawn. I do not understand how to erase the old message unless I keep a copy of the old text and rewrite it with the background color. If I just try to write a long text string with all blanks such as tstr = " " to erase the old message before I display the new message I have to make the text string extremely long as the character size for a space seems to be different then the character size for letters. Should I just display a rectangle of an appropriate size in the background color to erase my old text, or is there a better method of erasing this old text each time the window gets redrawn?
Thanks

Using Visual C++ 6.0 MFC in SDI application
I would like to put the & symbol in a dialog window to save some space instead of using the word "and", but the compiler recognizes the & symbol as a special character to associate the next letter as a command key. How do I just get the symbol with no special operation associated with it into the dialog window?
Thanks

Instead of single &, put &&. For Instance for getting string like this - "B&utton" put "B&&utton" as caption.

Jijo.

Hello!
I have created a custom edit control that uses COleDropTarget to accept/insert text drops. This works very fine.
However, when putting the edit control into a group control in the resource editor of Visual C++, the group control prevents the edit control from getting drag&drop notifications.
Is there any way to make the group control "forward" the drag&drop notifications? Or any other way such that the edit control sees the drop?
Best regards
Dominik
