hi everyone,
I am doing the unicode version of the project. The function of DragQueryFile(API) work well,but in the version of unicode, it is different from the version fo ansi, when I use this windows API, first it should return the count of file I have dragged, and I can get the path of each file, but it is not this, in the uncode vesion the value it return is likely the length of the file path, and when I get the path, I doesn't return the path in whole, It return the first character of the path.
for example, in ansi the value returned is 1(the count of file),"c:\test\li.txt"(file path) and in unicode the value returned the length of the path("c:\test\li.txt") and "c"(the path first character).
I am confusing about it long time. Is there anyone who has some thought about it, can tell me .
thanks advance.
lijie.

You're seeing just "c" because you're treating the string as if it were an MBCS string. The first two bytes are 63 00 (the UTF-16 encoding of 'c').

First thanks a lot,
but why ,why return the only first character, in the ansi version it can return the path of the file. And I have write a project in the unicode vesion use the function DragQueryFile it can return the path, and the count of the files which is dragged cann't return in the unicode vesion .

I have class CMySock derived from CAsyncSocket and that class has a member as
CMySock *pSock;
CMySock's object is created and kept in listen mode.When a connection reqest comes and CMySock's OnAccept() is called. There I want to connect to another system with pSock. and my code for that is
if(!(m_pSrcClientSocket->m_pDestClientSocket)->Create())<br />
{<br />
MessageBox("Falied to create a socket");<br />
}<br />
else<br />
{<br />
if(!(m_pSrcClientSocket->m_pDestClientSocket)->Connect(rs.GetAt(0),port))<br />
{
<br />
int err = GetLastError();<br />
MessageBox("Failed to connect to Connect");<br />
}<br />
else<br />
{<br />
}<br />
}
if the pointer is of CSocket instead of CMySock its connecting well.
I want to user CMySock only.
How to overcome this problem. Please help.
Thank you

Hi,
why would you connect to another system at function OnAccept()?
CMySock::OnAccept()
{
CMyClientSock *NewClientSock = new CMyClientSock();
Accept( NewClientSock, NULL, NULL );
//--> now the NewClientSock object is connected to the new incoming connection, you don't need construct / connect any object.
}

Hi, I am new to VC++. I have a list box in my window, i have checked the properties 'Horizontal scroll' 'Vertical scroll' and also 'Disble no scroll', to true.
But when I run the application, the scroll bars are disabled. Please let me know where I went wrong.

Hi,
But if you set the 'Horizontal scroll' 'Vertical scroll' to 'Disble no scroll', the scroll bars will be disabled. Cause your telling the compiler that you won't be using then by: 'Disble no scroll'.
Well, that is if I understand your question correctly.
Hope it helps.

Right ... After futher investigation ... How many items are in your list box, cause if there were only one | two, the scroll bars will be disabled, depending on the vertical size of the list box.

Thanq for the response..
I have many items in the list box, but only Vertical scroll is enabled..
horizontal scroll is not enabled though the text is exceeding the width of listbox..

Ok, so if I understand it correctly ... both of the scroll bars (Vertical & Horizontal) (in their properties) are enabled? And you have text that is exceeding the vertical and horizontal width | height of the object?
Just for interrest what complirer are you using?

Actually, the scroll bars will be enabled only if there are more items to be displayed in the list box.
Please check after inserting more items in the List box.

I suggest use from CListCtrl its better than CListBox
|

It seems the horizontal bar cannot be used as you expected. It is supported by the list box only in case of multicolumn lists, and does not perform horizontal scrolling for long items.
I think you can try an alternative solution based on "list control" instead of "list box" (available in Dialog Editor too). When a list control is used in Report mode, it looks like a list box with or without header, but with new features, like horizontal scrolling.
I hope this helps.
