Does anyone have some code snippets on how to use this undocumented
item? I have searched high and low for information; without results.
Apparently, Microsoft doesn't want anyone to use it for some reason.
I am trying to build a small app to work with a hard disk drive and am running Win XP.

Thanks much in advance!

How to put expand/collapse sign (+/-) in subitems

Hi!

I have a code downloaded (TreeListCtrl inherit from CListCtrl which supports treelist control in first column). It works fine except I need to put the (+/-) in subitems not in the first column (except the parent located in first column).

For further reference, please see my downloaded TreeListCtrl below (TreeListCtrl.cpp and TreeListCtrl.h):

CView *pView=(CHtmlViewEx*)pMain->GetActiveView();

I change:
pDoc->AddView(pNewView);
pDoc->RemoveView(pCurrView);
To:
CMainFrame->AddView(pDemoListView);
CMainFrame->RemoveView(pView);

I want to put the above code to the OnTreeDblClk() to implement when doulbe click the sub-item of the left tree,the CDemoListView will be showed on the right column.
But the initializtion of the left column and right column are:
CDemoTreeView and CHtmlViewEx.

There is not CDemoDoc in my program，There are only CMaiFrame and CSplitter(splitted window)

Is the above code possible to chage to adapt the implememtation I need?

I don't know what the CUNL_SignleView is and it's undefined.
when I compile the code,it said that the rectDefault，SetActiveView，RecalcLayout are undefiend.

Thanks for all senior programmer to read my post.

IE filetype location?

timothymfox1-Dec-05 10:28

1-Dec-05 10:28

Hi,

Thanks in advance for your help. In summary, what I'm trying to do is allow my application to be invoked from a browser with one of my registered filetypes without having to prompt the user to open the application.

I have an application that is intended to be called from a browser instance most of the time. Currently, my app makes registry entries that log the filetype and mimetype, and IE brings up a requster suggesting my application for the file, along with a checkbox allowing the user to automatically open my application when such a file is called.

I want to bypass this box as users find it confusing. Since it says open/save, sometimes they think they have to say "save" because the application will end up downloading a file to their computer. They'd just like that bypassed.

I tried thinking that perhaps I could just use javascript on the website to send the information to my application via COM, but I believe that the problem with that is SP2 security warnings will bring up user warnings using this, which defeats the purpose.

So, my first question is, does anyone know a way to override that requester and just train IE to call my application directly?

I know in firefox there is a file called downloads.rdf in which this information is ultimately stored -- so in the case of firefox I could theortically just write the entry to downloads.rdf myself. Is there a place where IE stores this information, for example, in the registry perhaps? That way, I could just write to that place in the registry during install and avoid this problem?

Or, perhaps there's another way to do it?

RIght now, the only registry keys are both done through the setup project in Visual Studio -- adding an association for my app's file extension in HKEY_CLASSES_ROOT, and the other one being the MimeType in the Content Types keys (HKEY_LOCAL_MACHINE/CLASSES/MIME/DATABASE/CONTENT TYPE/)

However, none of these registry entries are sufficient to automatically send the file type from Internet Explorer to my app -- currently that has to be done by the user, which is what I'm trying to change.

At a minimum, here are the registry keys/values you'll need. This example, timfox.exe, uses files with a .fox extension.

HKEY_CLASSES_ROOT\.fox = TimFox.Document
HKEY_CLASSES_ROOT\TimFox.Document\shell\open\command = TimFox.EXE %1
HKEY_CLASSES_ROOT\TimFox.Document\shell\open\ddeexec = [open("%1")]
HKEY_CLASSES_ROOT\TimFox.Document\shell\open\ddeexec\application = TIMFOX
; note: the application is optional
; (it defaults to the app name in "command")

HKEY_CLASSES_ROOT\TimFox.Document = TimFox Document

Edit control focus locks application

Hi,

I have a simple dialog box that has an edit control. I want the dialog box to come up with the cursor in the edit box ready for input. I can do this using myDialog::UpdateDialogControls(pWndCtrl, TRUE) but then the focus is locked on the edit control and I can't use the OK or CANCEL buttons and I have to use the task manager to end the application. I have also tried the GotoCtrl(pWndCtrl) with UpdateData() and UpdateWindow() and some other variations that seemed like they might work but they have no effect at all. This is probably very simple, I just can't seem to figure out the right command sequence.

The first control on the dialog that has an id other than IDC_STATIC will automatically get the initial focus. Otherwise, you'll need to call SetFocus(). If you opt for this, be sure and return FALSE from OnInitDialog().

Although it would seem that GotodlgCtrl(pEditCtrl) followed by SetFocus() should do the trick it doesn't. It needs to be in the syntax of GotoDlgCtrl(pEditCtrl->SetFocus());
