Either the parent frame is the desktop or the parent frame is a direct descendent of the desktop. Put a breakpoint on that line to see which of the two conditions is evaluating to FALSE.

Hi Raghunandan,

Did you subclass a view? It sounds like you are using a view where you should have a window. For example, CListCtrl is derived from CWnd but CListView is derived from CView.

Hi,
Mine is an SDI application where I do like this:
CSingleDocTemplate* pDocTemplate;
pDocTemplate = new CSingleDocTemplate(
IDR_MAINFRAME,
RUNTIME_CLASS(CConvertDoc),
RUNTIME_CLASS(CMainFrame),
RUNTIME_CLASS(CConvertView));
AddDocTemplate(pDocTemplate);

in my initinstance

CMainFrame is derived from CFrameWnd and CConvertView is derived from CEditView.

Is there any problme in this kind of creation?

UNC paths and CStdioFile

pranavamhari14-Jul-04 3:51

Hi,

My program uses 'GetspecialfolderPath(CSIDL_PERSONAL)' to retreive the my documents folder, and saves a file in the folder using CStdioFile.

On Win2000 this my-docs folder path is returned as an UNC path like '\\server\\..$\my documents\...'

Here, CStdioFile fails to create the file. I guess it is due to UNC name. How can I convert this to the mapped drive ?

or is there any workaround ?

Please help, thanks in advance to all.

Flash, IE and Click message...

Hi Gurus,
I got some kind of unusual program to do...
I am viewing a web page in Internet Explorer 6.0, and I got a flash object in that page. So, I want to ask you if it's technically possible to write program that will send OnClick message to the Internet Explorer window? And if it does can you give me some help how to do this thing, please. Or maybe some links would be helpful too...Thanx.

Some clarity needed...
1) are you talking about onclick from outside IE process -- external process telling IE that a key sequence has been entered?

2) communication between IE (browser window) and (Macromedia) Flash object?
* Flash object to browser window
* browser window to Flash object
* Flash object to another Flash object
(above three are documented at Macromedia (Flash) site, see "communicating between objects")

Good luck, sounds like interesting stuff you're 'bout to do!

1) Yes, I want to write a windows or .NET application with button on the form, and when I run this application and click button on the form a message LB_MOUSE_CLICK (or something, I just don't remember because I've not used MFC since 2002) will be send to IE window.

2)Excuse me, but I think I do not understand you clearly... I mean that there is a web site and on the one of the web pages of this website there is a flash object and I want send ON_CLICK message to that IE window wich is currently displaying web page with flash object, from my Win32 or .NET application

Thank you,

Where I have to specify my file path and LR_LOADFROMFILE is not supported by WinCE,It shows that undeclared identifier, When I refered MSDN and put Zero instead of LR_LOADFROMFILE.

While help for LoadImage() does not say that LR_LOADFROMFILE can be used for the fuLoad parameter, it does mention it in the lpszName section as though it is a possibility. Have you search through each of the .H files to see if it is defined?

You may want to ask nicely in future.

Seeing as I am in a nice mood today. What exactly do you want. I could show you some code that uses MAPI. That will achieve what you want!

My main .cpp file is getting too big

My main .cpp file is getting too big.

I tried to create a new file to place all new functions to the main class, but then run into compiler errors.

Are they a simple way of splitting up a large file into several smaller files and not running into the mess as to what headers to include.

I thought that Visual Studio would have managed this when I add new funtions (via the IDE) but No!

Typical error

c:\My_Example\My_ExampleDlg.h(42): error C2065: 'IDD_MY_EXAMPLE_DIALOG' : undeclared identifier

But when I place all the functions into a single file all is OK.
