What would you expect to happen when a bitmap is placed over the other controls? Explain in more detail what you are trying to accomplish and maybe a more suitable solution can be offered.

There is no MSDN forum. If you are referring to the microsoft.public.vc.mfc newsgroup, you received two responses within an hour after your post. One of them referred you to here.

Hello,

Can you help me? I have some questions about C++.
Right now I learn how to write code in C++, I am a newbie.

1. I make a simple application that needs binding data from Microsoft access to datagrid using Microsoft jet driver, can you make a simple function for it or maybe a sample?
2. I also want to make the application that can update the dataset and database; can you give me another sample of it?
3. Can you make a sample for adding data from textbox and updating it to database?

I hope it’s not too much, I need your help so I can learn write the code from you. Thanks.

go through the ADO library. It is COM component implemented some easy to use interfaces. If u dont know how to use the com components, first learn that. becasue, most of the library is coming with the com technology.

Detecting file association changes and getting new icon

I'm trying to write a simple file manager and want to be able to detect changes to file associations, and then get the new/changed icons. Getting the notification isn't so hard, but the it's what to do when
I get it that is the problem. I get icons from the system by calling SHGetFileInfo() and unfortunately this function seems to cache the icon indexes in the system image list for a given filetype. So even if the icon for say, mp3 files, has been changed by the user while my application is running, SHGetFileInfo() still reports the original icon index.

Any ideas ?

How to chage attributes for a directory?

hfrmobile9-May-05 19:50

Changing file attributes for a file is no problem (e.g. using the SetFileAttributes() function).

Is there an equivalent for doing this for a directory?

Thanks in advance, hfr
Sigh | :sigh:

PS: if using SetFileAttributes() for a directory I get a HRESULT of 2 which means: file not found

David Crow10-May-05 2:19

This works for me:

if (! SetFileAttributes("c:\\ResOrg", FILE_ATTRIBUTE_READONLY))
{
    DWORD dwError = GetLastError();
}

Hi thanks for your reply!

Sorry, I was a bit inaccurately...

I am using RAPI version of SetFileAttributes() --> CeSetFileAttributes() because I need to do this on a remote device (on a Pocket PC running Windows CE)

It seems that there is a difference between SetFileAttributes() and CeSetFileAttributes().

CeSetFileAttributes() works fine for files but not for directories. The only thing I have found about this issue is that the .NET Compact Framework does not support changing attributes on directories... (files are supported).

Since the project is written in VC++ this should not matter...

CeSetFileAttributes() always returns false and CeGetLastError() returns 0x2 (file not found...)

Any idea why CeSetFileAttributes() does not work for directories?

thx

D'Oh! | :doh:

No. I've no experience with CE or the .Net framework. What folder attribute are you wanting to alter? If I am reading the documentation correctly, it states that an application cannot change the attributes of a directory in the RAM file system. Does that apply to your situation?

I assume you mean ROM, not RAM?

Of course I do not try to alter attributes of a directory which is located in ROM. In this case I'll expect a "access denied" error...

I'd like to change directory's attributes which are located in RAM or on a storage card.

I can delete or rename the directories but I cannot change the "r" or "h" attribute...

No, RAM was the intended word. See here.

Very interesting... thx!

This code (see comments) demonstrates what happens:

<br />
CeRapiInit();<br />
<br />
// "\\CF-Card\\Temp"<br />
// "\\SD-MMCard\\Temp"<br />
// "\\Temp\\Test"<br />
CString strFileName = "\\SD-MMCard\\Temp";<br />
<br />
wchar_t wcFileName[256];<br />
mbstowcs(wcFileName, strFileName, strFileName.GetLength()+1);<br />
<br />
DWORD dwAttributes = CeGetFileAttributes(wcFileName); // works always<br />
HRESULT hr = CeGetLastError();<br />
<br />
dwAttributes |= FILE_ATTRIBUTE_READONLY;<br />
<br />
// hr = 0x00000002 "The system cannot find the file specified." if dir is in RAM<br />
// hr = 0x00000005 "Access is denied." if dir is on storage card<br />
// this problems only occur using RAPI<br />
CeSetFileAttributes(wcFileName, dwAttributes);<br />
hr = CeGetLastError();<br />
<br />
CeRapiUninit();<br />

RAM: "The system cannot find the file specified." (ok, since MSDN says it is not supported

Storage Cards: "Access is denied." (also not supported? Cry | :((

)
