I can't get SHGetFileInfo's SHGFI_ICONLOCATION to work. (I'm on WinXP.) That option requests the path to the file that contains the icon for a given file type.
Here's my code:
#include <windows.h>
#include <stdio.h>
void main()
{
SHFILEINFO fileInfo = {0};
if (SHGetFileInfo(".txt", FILE_ATTRIBUTE_NORMAL, &fileInfo, sizeof(fileInfo),
SHGFI_USEFILEATTRIBUTES|SHGFI_ICONLOCATION|SHGFI_TYPENAME))
{
printf("file type: '%s'\n", fileInfo.szTypeName);
printf("icon file: '%s'\n", fileInfo.szDisplayName);
printf("icon index within icon file: %d\n", fileInfo.iIcon);
}
else
printf("failed\n");
}
The output I get is:
file type: 'Text Document'
icon file: ''
icon index within icon file: 3
As you can see, it correctly determines the file type. Also '3' is correct -- I can see that in the registry (under "txtfile"). But the filename is missing, even though it is there in my registry.
I've tried a few variations -- e.g. different extensions, and different sets of SHGFI_* flags. Anyone know how to get this to work?
Thanks -mike

try
::memset(&fileInfo, 0, sizeof(SHFILEINFO));
before you call the function

Actually the code does the equivalent of the memset() already. It starts with
SHFILEINFO fileInfo = {0};
... and, per standard C/C++, "= {0}" will initialize the ENTIRE struct (not just the first member) to all zeroes.

I posted this couple of weeks ago, and didn't finished it until today ...
Am I Stupid ? Did I missed something ?
I want to be notified when my slider control receives the input focus...
...
afx_msg void OnSliderFocus(NMHDR * pNotifyStruct, LRESULT * result );
... Should the following be called When I either click with the mouse on the slider ? or when I TAB to it ?
ON_NOTIFY( NM_SETFOCUS, IDC_SLIDER1, OnSliderFocus )
...
void CTestColorControlDlg::OnSliderFocus(NMHDR * pNotifyStruct, LRESULT * result )
{
ASSERT( 0 );
}
...
Thanks, I'm clueless

Can someone point me to an article on how to add a second window to my application (using API)?
I know that you might just tell me to use Dialogboxes, but I would rather just use another window. I made it as far as making a second window class, but am not sure what to do about the mainwindow loop. Also, what to do about the second window proc. And I'm not talking about a child window, I'm talking like in Visual Basic when you add a second form to the project.
I checked out the faq, but there doesn't seem to be anything applicable...
While we're at it, how would you make a window so that the user can't change it's size?
Thanks guys.

Which kind of application do you have ? MDI, SDI, Dialog ? What will be the second window for ?
AFAIK, you can create another window in the Win32 API just like you did for the first one, each having their own message loop.
Why can't the second window be a child window ?

The program is a SDI, it will be used to create, edit, and administer tests to students. There is a main form, which basically provides a menu of what is to be done, ie. create a new test. These tests will either be printed out, or taken on the computer, and will only consist of short answer or multiple choice questions.
So, in the end, it will need
a) the main form
b) a form to create the test file
c) a form to design the test
d) a form to take the test
e) a results form
and the list goes on.
The second window can't be a child window because the first form will be disapeared while any other forms are active.
I figured that the second window would be made the same way, but I saw potential problems with the
while(GetMessage(&Msg, NULL, 0, 0) > 0)
{
TranslateMessage(&Msg);
DispatchMessage(&Msg);
}

I just finished trying it out, and it works.
Just declaring a new WNDCLASSEX object, with the same hInstance, the same MSG, and a new WindowProc... and it worked fine.

In this day when .NET is about to be out with its second version, and MFC has been around for some 10 years, I can't fathom anyone using the Win32 API to do Windows programming! 
Nevertheless, it's a good learning experience. Good luck!

I want my messagebox to automatically vanish after a few seconds....I will probably be emitting it in my View class...ANy hints? Thanks

Use this and give it a callback procedure.
int MessageBoxIndirect(
LPMSGBOXPARAMS lpMsgBoxParams // address of structure for message
// box parameters
);
Then you can just fire a message to the box when you are finished and close the dialog when you recieve that message.
OR,
use the same creation method, but in the WM_CREATE, start a timer and in your callback when you handle the WM_TIMER, you can just kill the dialog.
Hope this helps!

The best way is to not use a standard MessageBox but your own dialog box. Inside it you can add a timer to close it after a certain amount of time.
I recommend that you also let the user know that in 10, 9, 8, ... the dialog box will close.

Is there a way to call this function and have it not "Beep" ?
Dan Willis

Beep? I didn't know it did!
Perhaps it's a Windows setting. Check the Control Panel/Sounds applet.

Hi,
I have a simple question.
When I create a MFC project using wizard, All the created files are in the same folder.
I would like to put all the *.h (including resource.h)into a folder named "MFC header" and all the *.cpp int another one named "MFC source". Also, I want to put Myproject.rc into the "res" folder. Is there a good way to do that so that I dont have dependency problems?
I use VS.NET architect enterprise
Regards,
Mykel
Everything's beautiful if you look at it long enough...
