Using the Win32 API, I wish to write a method that sets the column width of each column in a listview control. GetItemCount returns rows and I am looking for number of columns. Any suggestions?
CMDI::SetColWidth(HWND hWnd)
{
int items = ListView_GetItemCount(hWnd
for (int i = 0;i < items;i++)
{
ListView_SetColumnWidth(hW
}
}

My peers at work told me to save off the number also and I'll try that. I am adding the code to a base class and I didn't want to pass the number of columns if I didn't have to to make the code more generic. I thought maybe some call to the listview would return the column count or allowed you to interate thru them.
The listview contains a Header control that draws the column-headers. You can get a pointer to this header, and then send a message to the header to get the item count (=column count).
Use ListView_GetHeader (or LVM_GETHEADER message) to get a pointer to the header control
Use Header_GetItemCount (or HDM_GETITEMCOUNT message) on the header control to get no of columns

you can try Listview_GetColumn and loop until it returns false MIGHT work. but youre program should know the amount of columns because you have to add them at some point. just save the #
