This is because he childframe is not yet created.
Try implementing the same code in the mainframe class or the app class.

There are many details to change to do what you need to do. I hope I understand what you are trying to do. I assume you want to use CFormView.

It is easier to create a new class that is derived from CFormView. Then use that class instead of the class that the wizard generates derived from CView. You can delete the old child view when you are sure you don't need it; you probably won't use it when you have made all the changes.

One place you might need to change is the call to LoadFrame, but I forget the details. I don't use MDI very much so these instructions might need to be modified for MDI; I am trying to do all this from memory so some of what I say might be the SDI way. One modification is that it helps to have a document, so you probably want to create a document class. Then allocate a new instance of the document for every child window. There is probably a LoadFrame or it's equivalent in the child frame window. Then put the address of the document in a CCreateContext and pass the instance of it to LoadFrame.

DLL Search path while debugging

Hi all -

I am using Visual Studio .net 2003 for development on Win XP. My application picks up dll from PATH variable. But when I run the application (Double clicking the application in the Release or Debug folder), it is able to find the dll. But when I debug from the environment, it fails to find the dll from the PATH variable.
Any ideas?

Regards
Misha Grewal

You need to include vcclr.h.

If your only need is XML document handling why not use a native lib for dealing with the XML documents? There are even a couple here on CP

Save configuration problem

Julia17-Dec-06 0:10

Julia1

7-Dec-06 0:10

I have an enterprise template project on VC7 .NET.
When I enter the "Configuration manager" , I see that in Debug configuration one of the projects is not checked in the "Build" column, and thus this project is not compiled when I am building the solution. I check the project in the Build column, close the configuration manager window. The build solution now includes also the project that was not checked. But when I close and reopen the sln, this information is lost and the configuration manager window shows that project as unchecked.
This seems as a bug of the studio . . . ?!!???, is there a way to make my solution configuration to include unchecked project also?

Thanks in advance,
Julia.

Can I specify file name to get handle file?

The "open file dialog box" does not provide a handle even if you wanted it to.

What do you need the handle for?

It depends on your requirements and preferences and such. Are you using MFC?

Did you look at the documentation of OpenFile?

Use SetFileTime() for this. The handle is returned from CreateFile().
