Hmmm, so you don't agree with Tom? (see above) Because that was along the lines of what I was thinking.

I agree with Neville. It looks like there may be something awry in your code.

However, you need to find out why an incremental build is not building the binaries that need to be built for the app to run.
I certainly agree with this, but in my experience VC doesn't get this wrong as long as you've got the project and it's dependencies set up correctly.
If you do a Rebuild All and then it happens again and none of the dependant code has changed, then me thinks it must be a problem in your code.

It only happens if I do a normal build (F7) but is fine after I rebuild all.

I don't know if this really getting anyone anywhere. Why don't you jump into the debugger and track down the exception.

Tom is right in that you're likely run into weird behavior if VC++ doesn't get the dependencies right. And a "rebuild all" forces recompilation of all modules, thereby getting around a bad dependency check.
But I suspect the real problem may lie in the code. I've often run into annoying situations (my fault) when I forget to delete an unused #define from resource.h. It causes no end of problems until I figure out that I'm calling GetDlgItem() with a bogus id. Although the ASSERTs I liberally sprinkle my code with will usually catch that. But annoying all the same.

Very good point, Ravi. That's why while it doesn't hurt anything to do rebuilds, I let him know that it's probably a dependency issue so that he can start looking in that area.

It may be worth checking your clocks date/time and seeing if its set to earlier then some of the .cpp/.h files of your project. This can cause the project to only build partially after a change and link using old .obj files.

Any recommendations for good books on getting started with Managed C++. Preferably aimed at experienced C++ developers.

Hi Michael,
I personally enjoyed very much the MS Press Step By Step book. You do have to wade through a few "this is a variable" type sections. However, I personally don't mind that as I enjoy the tutorial, sequential steps approach as it quickly gets me through the demos of what I need to learn. I will add the caveat that if you've already been doing a lot of MC++, this book will be a waste for you.
I also have the APress book, but I just do not like the format of their books at all.
Cheers,
Tom Archer

Hey Tom
This is slightly off-topic. But are there any 3rd party form designer tools for use with MC++?

I'm sure there will be and I've even had friends talk of writing one, but I haven't seen one yet.

If an MC++ form designer comes out I bet I'll prefer that to VS.NET except maybe for MSDN

Thanks, I'll have a look at the MS Press book.
What about the "Visual C++.NET Bible" (assuming you are the same Tom Archer)? What kind of stuff does that cover?

It's me
However, the VC++ .NET bible is named that simply because the product is now affixed with the .NET label whether you use it to write managed extensions or MFC. My book is an MFC book with about 5 chapters on managed extensions, which is why I didn't mention it.

Ok, I'll wait and see what the MS Press one is like first. I might have a look at your book later.

I've never seen my reviews over there. The "Petzold of C#"? That might be just a bit of hyperbole I'll take it though!!
Anwyay, I have no idea why it's not listed on the UK Amazon. It should be in stores this week and I know that US Amazon is shipping it now. I'll ask the publisher tomorrow.

can anyone tell me which program that i have to use to create avi file..
i want to use canimation in mfc.. but need avi file. i have never seen avi in my life. don't know how to create either..
i know for BMP file, i can use adobe photoshop, paint program and some other drawing programs. but what is avi?? how to create one my own.
what i really want is an animated .gif file. is avi is the same thing like .gif file???

avi I thought was audio video something (interchange maybe).
animated gif's are similar but no sound...
Theres tons of free tools that will create AVI's for you from bitmaps and such...
Maybe Flash has a tool to convert *.swf files to avi's
Check out www.wotsit.org for full details on the AVI file structure.

There are a number of applications that can be used to both execute and create AVI files on download.com

Hi.
I am working on a multiview program (two views). The design is done; however, I just found out I cannot cast GetActiveView() in main to any view I want. For example, let say I am in main and the active view is View#1, but I want to send a message or call a function in View#2.
How do you access *any* view, active or inactive, from main?
Thanks,
Kuphryn

Like many things in MFC, there are many answers here and it comes down to personal choice and your system design:
1) You could call the document's UpdateAllViews function and pass the desired message & data that way.
2) You could store the view pointers in a central place (such as the app object or the mainframe object) and then call a member functions to either send the data from that main object or to return the pointer so that you could then directly call the view's member functions
In situations like these there is no right or wrong way although I typically like to use the built in UpdateAllViews method.

I tend to store pointers to each view in my CWinApp derived class. I'm not sure it is the best way, but it works well for me as I tend to have multiple views connected to just one document class.
