ReDim

Hi Guys

Will that work? I have This API:

Code:

---


Public Declare Function Shell_NotifyIcon Lib "shell32" Alias "Shell_NotifyIconA" (ByVal dwMessage As Long, pnid As NOTIFYICONDATA) As Boolean
    Public Declare Function SetForegroundWindow Lib "user32" (ByVal hWnd As Long) As Long
    Public Declare Function SetWindowPos Lib "user32" (ByVal hWnd As Long, ByVal hWndInsertAfter As Long, ByVal X As Long, ByVal Y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long
   
        Public Type NOTIFYICONDATA
            cbSize                          As Long
            hWnd                            As Long
            uID                              As Long
            uFlags                          As Long
            uCallbackMessage                As Long
            hIcon                            As Long
            szTip                            As String * 128
            dwState                          As Long
            dwStateMask                      As Long
            szInfo                          As String * 256
            uTimeout                        As Long
            szInfoTitle                      As String * 64
            dwInfoFlags                      As Long
        End Type

Because of the limitation of "szinfo as string 256" I need to be able to make szinfo with no limit. can ReDim it? if yes how can I do that?

Thanks

AFAIK you cant change it by simply, becuase the NOTIFYICONDATA have to be specified the string in the exact lenght, otherwise memory issues will occur.

Per MSDN (great resource when needing to understand APIs), the szInfo structure is the balloon text and is limited to 256 characters, including, the null terminator. So really it is 255 characters worth of text. Setting it to > 256 should cause the API to read the structure incorrectly & I would expect a crash of the systray at worse. At best, only 255 characters used anyway -- just a guess there.

I guess there is no work around this, unless I have to use another alternative then the API, and szinfo, Maybe there is an OCX option that uses some kind of html. anyone knows of any alternative for balloon message then the API mentioned?

What are you trying to display in a ToolTip (balloon is still a tip) - book or something?
255 chars is more than enough - if you need to present large text then pop some form on the screen with multiline standard textbox or richtextbox.

Or, try this. Great example, easy to use.
