i can not show the full buffer for subitem #2, it shows only 256 byte only while the addbuffer ==AddBuff db 1024 dup(0)
why? example would be better......thanks
mov lvi.imask,LVIF_TEXT; or LVIF_PARAM or LVIF_STATE
m2m lvi.iItem,row
mov lvi.iSubItem,0
mov lvi.pszText,offset empty
mov lvi.cchTextMax,sizeof empty
invoke SendMessage,hlistview,LVM_INSERTITEM,0,addr lvi
inc lvi.iSubItem
mov lvi.pszText,offset cbbuff
mov lvi.cchTextMax,sizeof cbbuff
invoke SendMessage,hlistview,LVM_SETITEM,0,addr lvi
inc lvi.iSubItem
mov lvi.cchTextMax,sizeof AddBuff
mov lvi.pszText,offset AddBuff
invoke SendMessage,hlistview,LVM_SETITEM,0,addr lvi
Its a limitation of the ListView control as stated in the MSDN:
pszText
If the structure specifies item attributes, pszText is a pointer to a null-terminated string containing the item text. If the structure receives item attributes, pszText is a pointer to a buffer that receives the item text. Note that although the list-view control allows any length string to be stored as item text, only the first 260 TCHARs are displayed.
no one discover a trick to override this limtation
Thanks
The limitation is on the number of chars displayed, not the number of chars that can be stored - which can be (I assume) up to the limit of RAM.
Try to guess how long an icon name can be on the desktop (eh? jimg heh heh), it can be as long as the day is short in Greenland in winter...but only the first 260 chars are shown...
Funnily enough, 260 is the maximum length of a path - 256 chars, plus another 3 (C:\), plus the terminating zero (thanks, C).

Custom controls, you can write your own listview like control and do whatever you like to it. For an example you might visit Ketil's site and check out RAGrid.

Hey guys. I'm doing a Resource Enumerator that uses several listview controls to show items of each specified Type. I don't know things work fine except when i enable comctl version 6. The listview controls show neither the item text nor the image. I only used the LVIF_TEXT+LVIF_IMAGE of LVITEM Struct. I used a beeper when sending the LVM_INSERTITEM to check if it returned null and it beeped. Does anyone have a clue to what is going on?
Thanks guys.

Hey...Problem fixed with LVM_REDRAWITEMS. Thanks guys
Bye and best regards from X.
Hi to all,
In windows 95, 98 and some other ones the maximum length of a path was 260. But with ntfs there is a new problem. The ntfs filesystem supports paths of more than 32000 characters. To use this paths we must prepend the string with: \\?\. With this prefix the function speak directly with the filesystem.
But the problem does not finish here. There is some functions that work with the prefix and some ones that do not work at all. An important example is SHFileOperation that do not work with the prefix. And you must work with UNICODE characters if you want to use this prefix. This is an extract of the explanation of the CreateFile first parameter:
"In the ANSI version of this function, the name is limited to MAX_PATH characters. To extend this limit to 32,767 wide characters, call the Unicode version of the function and prepend "\\?\" to the path."
I hope that this could be useful to someone.
