And what is that error?

Not sure I understand this. Are you wanting one set of source code, but two separate exe files?

You would get more help if you describe your problems in English.
以前你也用中文在这里叫过吧？鬼佬们不懂中文，白瞎了~~
个人理解，仅供参考：
win32程序在win64上面是通过wow64工作的，被。64位程隔离在一个独立的环境里面序和32位程序在用户层不可互访。因此没有办法只用一个程序在64位和32位间无缝转换。即64环境中必须用64的程序才能安装64位的驱动，32位环境中只能用32位程序安装驱动。
不过完全可以做到在源代码层面统一。

Hi xjh_sz,
I believe that you are doing the correct thing by creating two separate installers for 32 and 64 bit. UpdateDriverForPlugAndPlayDevices does not support WOW64. You might be able to get your 32 bit installer to work by calling Wow64EnableWow64FsRedirection[^] but I honestly don't know for sure.
Some additional documentation:

First,thanks for your replies.I am sorry to you because I asked question in chinese.
My question is as fllows.
I recently created a driver installation program, which uses a number of core functions such as UpdateDriverforPlugAndDevice(), using vs2008, in 32-bit operating system everything is working properly. But win32 program can run in x64, but under x64 it does not work. For example UpdateDriverForPlugandPlayDevices() raises an error, I used GetLastError (), and I see an error code. Later I was using a 64-bit system with vs2008 and compiled the x64 program, everything works fine, but the program can not run in win32. The problem is now solved, but I now maintain two versions of the installer 32 and 64; I do not know what a better way, I just run a seperate version of the executable.

How did you try to delete the columns?

I suspect you're giving the column index to the DeleteColumn function.
Instead always use the index of 0.
This is from the documentation of DeleteColumn.
int nColumnCount = m_myListCtrl.GetHeaderCtrl()->GetItemCount();
for (int i=0; i < nColumnCount; i++)
{
m_myListCtrl.DeleteColumn(0);
}

In addition to this, one also might want to use m_myListCtrl.SetRedraw() around those list operations to improve performance and reduce animation effects. Maybe even using a RAII like implementation for it.

Hello,
as most of you know, you can fill a Listbox with a complete directory list by Sending a message LB_DIR. This works fine, for example I create a CListBox Control like this, and fill the contents with a directory list:
CListBox m_List1;
...
m_List.SendMessage(LB_DIR,DDL_READWRITE ,(long)(const char*)(CString("C:\\temp\\*.*").GetBuffer(0)));
(Alternatively, you can use
m_List.Dir(DDL_READWRITE, "C:\\temp\\*.*");
which leads to exactly the same result)
The problem I have is the following: if a file in my directory has not set any of the following bits:
- "File is ready for archiving"
- "For fast searching, allow Indexing service to index this file"
it won't appear in my list. In order to do this, use Windows explorer, right-click on a file, select properties, look at Attributes and click the button "Advanced", and remove the upper two checkboxes.
No matter what attributes I set, when these two checkboxes are not set, the file will not be listed.
Can you please try to reproduce this? I think this is a severe bug that Microsoft should fix, or am I doing something completely wrong? How can I overcome this behaviour? Is there any known fix to this issue?

m_list.Dir(DDL_READWRITE, "C:\\temp\\*.*");
tried and works fine for me..

Works the same way here too, if none of those attributtes are set then the files do not appear in the listbox, don't know what causes this and how you can fix it (aside of forgetting about it and writing your own code to fill the list using FindFirstFile[^], FindNextFile[^] and FindClose[^] or somesuch)

I have run some tests on this and it appears that the removal of the "For fast searching, allow Indexing service to index this file" bit is the problem. If this bit is set then the file appears in my list, even if the Archive bit is not set. This may have something to do with the way the bit is interpreted as a 'not' option, as described by dir /?.
Using FindFirstFile() / FindNextFile() I get all the files, including the one with indexing not set (attribute 0x2000), so it definitely looks like a Microsoft bug.
It's time for a new signature.

Thanks alot, as for the other two persons who were not able to reproduce this behaviour: which OS do you use? I have only XP Pro for testing, and I can reproduce it on every XP machine available in my office.

I'm on Windows 7 Home Premium, it looks like this has been around for some time.

Thanks, so it's obviously not fixed in Win7, does anybody know how to report this directly to Microsoft? Any chance they will do anything to fix this?

I'm 99% sure they won't. First, it's been around for a long time so there's a chance that some applications rely upon it. Second, no data is being lost so it would be very low priority. Third, there is a workaround.
