Windows Explorer File Properties- ATL

I think this is the standard listctrl behavior, that is when you click outside the control it loses focus, and unfortunately I think there's no simple work-around.
You could try to set againg the focus to the listctrl when the parent dialog becomes active, that is it's receiving a WM_ACTIVATE message. Maybe you should do it once only after the warning messagebox is closed, otherwise every activation would set the focus to the listctrl and the user could get confused.
I think you can't set the focus in the notification handler for the LVN_ENDLABELEDIT, because the WM_KILLFOCUS message can't be processed while you are in a message handler, so the control still has the focus there.

What is the command to set the focus on one of the Listview items in random?

I mean if I go SendMessage, what parameters should I send?

Hi,

I don't think you're going to be able to find this address. If you run the Dependency Viewer (depends.exe) you'll be able to see all of the function entry points of the various modules included in your program, but I'd say that bfdf388d is way out of their address range.

Have you tried running your program in the debugger and catching ALL exceptions? Then the debugger will stop at the point at which the exception is raised which should help you track down the problem.

Hope this helps.

Okay, I have been working on this forever, but I have a file properties dialog in our application. I also have Windows Explorer using my DLL. I need to research the following things, and I hope y'all can help a confused gal:

(1) How can I have the Windows Explorer provided General Tab Property page show up in my application? I have created my own, but I prefer using the system's.

(2) Where in the world is the data persisted? Stuff like Comments, Author and other data located on the Summary Tab- where is this saved? On the registry? How can I obtain and save it myself? I have been just persisting and reading from an XML file, but I have no idea what's going on with the system stuff.

Please Help Confused | :confused:

Thanks,
Lilian

Where in the world is the data persisted?

If you're using W2K, it's stored in a 'Document Summary Info' stream. Alternate file streams are a NTFS-only feature. Write something at a 'Summary' page, then drag the file to A: - you'll see the warning about data loss; only the main stream will be copied to floppy.

Thanks for the info! ;0

Do you have any idea where I can access this stream? I am really at a loss when it comes to Windows APIs.

Using .lib - How?

29-Aug-01 6:06

Hi,

could anyone help me to understand how IDE of VC++ works for linking?
I've developed some control, which resides in two files : "dummycontrol.h" and "dummycontrol.cpp".
Now I need to use it in another project. I want it to be like all other libraries, i.e. I want to just write "include "dummycontrol.h"" in cpp file of the other project, and linker will pick it up automatically.

I've created dummycontrol.lib, and put into IDE path to that directory. In that another project I've put that include line, but during linking I've got error "unresolvable sybmbol __dummycontrol::dummycontrol() etc". I was able to link only when I explicitly put full path to the module on project's link page in "Object/library modules" list.

What I'm doing wrong or where is RTFM?

Thanks a lot!

#pragma comment(lib, "yourlib") will do the trick. You'll probably use two #pragmas in #if/#else/#endif, one for debug and one for release. Note that there's no path - you should place the .lib file in one of the dirs listed in Options/Directories/Library files.

I was able to link only when I explicitly put full path to the module

Hmmm... including just the 'yourlib.lib' in the Object/Library modules didn't work?

Tomasz, thank you for replay.

Where exacly should I place this #pragma macros (what file)? I'm very new to VC++ - just moved from Delphi, and main headache is all these macros, includes and link options Cry | :((

(.

About including just the 'yourlib.lib' in the Object/Library modules - it works.

In the .h file of your control:

#ifdef _DEBUG
#pragma comment(lib, "yourlibD")
#else
#pragma comment(lib, "yourlib")
#endif

Note that names for debug and release libs should be different. Appending 'D' to the name of library for debug builds is a popular naming convention.

Two active windows at the same time

You can put the code that makes up you lib files into a new Win 32 Static or Dll lib project from the new project wizard. Then in the other workspace where you want to use the library, goto the Project menu -> Insert into Project Workspace, and select the .dsp file of the Static lib, remebering to make it a dependency of your new project.

All you have to do then is include the header files for you class\classes that you wish to use.

Hmmm, does this make sense? Hope it helps.

In MS Word 97, when I drag any toolbar (such as drawing toolbar) and drop it on the Word window, it becomes a window with small title bar. It makes me surprised that when I click on a button on the toolbar, the cursor on MS Word window still blink and MS Word window is still active. Vice versus, when I type, the toolbar window is still active. I try to create a window like that by the API Fuction CreateWindowEx and set window style as WS_Ex_TOOLWINDOW, and its parent as another window;
However, this window becomes de-active when I click on its parent window. I wish to receive any explaination for this phenomenon. Thank you very much.

What means "container" on a LAN?

What means "container" on a LAN?
(in the description of "NETRESOURCE" in MSDN)

Is a shared file folder a "container"?

Is a "Work Group" a "container"?

Thanks.

Paolo Messina29-Aug-01 12:52

A workgroup is surely a RESOURCEUSAGE_CONTAINER, but I think a shared directory or printer is not.
Btw, have a look at this article: http://www.codeproject.com/treectrl/networktreectrl.asp
It may help you to understand how to call WNetOpenEnum.

Thanks again my pal.

I have read your article you introduced to me. It helps a lot.

But I still have a question, that is, are there any other typies of "container" besides "Work Group" on the LAN?

Best regards.

Well, I don't know Smile | :)

This is from WinNetWk.h:

#define RESOURCEDISPLAYTYPE_GENERIC        0x00000000
#define RESOURCEDISPLAYTYPE_DOMAIN         0x00000001
#define RESOURCEDISPLAYTYPE_SERVER         0x00000002
#define RESOURCEDISPLAYTYPE_SHARE          0x00000003
#define RESOURCEDISPLAYTYPE_FILE           0x00000004
#define RESOURCEDISPLAYTYPE_GROUP          0x00000005
#if(WINVER >= 0x0400)
#define RESOURCEDISPLAYTYPE_NETWORK        0x00000006
#define RESOURCEDISPLAYTYPE_ROOT           0x00000007
#define RESOURCEDISPLAYTYPE_SHAREADMIN     0x00000008
#define RESOURCEDISPLAYTYPE_DIRECTORY      0x00000009
#endif /* WINVER >= 0x0400 */
#define RESOURCEDISPLAYTYPE_TREE           0x0000000A
#if(WINVER >= 0x0400)
#define RESOURCEDISPLAYTYPE_NDSCONTAINER   0x0000000B
#endif /* WINVER >= 0x0400 */

My guess is that a container is: ROOT, NETWORK, SHAREADMIN, NDSCONTAINER, GROUP, DOMAIN, SERVER, maybe TREE
But absolutely not sure! Smile | :)

Thanks again.

But if I do not know the typies of "container", how can I know whether a "NETRESOURCE" is a container that contain sub-"NETRESOURCE"?
From which flag can I know?

Best regards.

Paolo Messina30-Aug-01 23:15

The RESOURCEUSAGE_CONTAINER does this, but to know if it actually contains something you have to call WNetOpenEnum().
