Goto Resource Menu. select toolbar. then select the last icon. this can be modified according to your needs. you just need to drag and drop the menu items to the place where you like.
All the best.

dear all

note: probably one library has several classes, so how can i know which library i can use or how to use it?

Are you exporting the C++ class from the DLL?
If so, the member function names are mangled and exported.
Use a tool like depends.exe that comes along with Visual Studio and look at the exported function name.
Use the same name in your VB code.

thanks a lot. i have read the articles how to export functions names in .dll. but this .dll was created by user. so here i just got .dll. nothing else, so how to export the function names? thanks.

Do you mean somebody else has created the dll and not you?
If so, the functions have already been exported.
Use Dependency Viewer (depends.exe) and open the dll file.
It will list all the functions that have been exported.
Check the actual name of the function and use that in the VB code.

my code is following:
Private Declare Function DataFormat Lib "icon_vc80_40d.dll" (ByVal cpIpAddress As String, _
ByVal dnsFlag As Boolean) As Boolean
Private Sub Command1_Click()
Dim a As String
Dim b As Boolean
Dim c As String
a = Text1.Text
c = DataFormat(a, True)
Text2.Text = c
End Sub
i used this code to test the .dll, but the error occurred: didn't find .dll file. or couldn't find entry point of .dll. what is problem?
Note: ICON_API icon::DataFormat::DataFormat ( const DataFormat& df,
bool cloneComponents = true
)
Copy constructor.
Parameters:
[in] df DataFormat object to copy.
[in] cloneComponents Specifies if a deep or shallow copy is made.
Thread Safety:
Not thread safe. The data being copied can change at any time.
could you help me to check, is this right? the Note above just showed dataformat() detail.

I guess only c functions exported from the dll can be called from VB.

thanks for your reply. i knew i need to export the c++ dll function first, and then i can call it. but i don't know how to export step by step? i got the dll already. how to export? please help me. thanks a lot

You can call a c function exported in a c/c++ dll from a VB application. And to export a c function all you have to do is put the following keywords in front of the function to export as shown below
extern "C" __declspec( dllexport ) void AnotherCFunc();
extern "C" - is used to avoid the name mangling

thanks a lot for your help. my one .dll has several classes, so how i can use these funtion properly in vb. thanks a lot

As I said before you cannot call a c++ class's member function from a vb app.

thanks, how i can export the functions of dll step by step? thanks a lot

If you haven't DLL source code then you can't. However, you may develop (with C/C++) a new DLL that will act as wrapper of the original one (i.e. an adapter [^]). For details on building a VB6 callable DLL, see this great article series [^].

Hi ,
In my application I am using NOTIFYICONDATA structure to show tool tip. here the szTip can only contain 128 charecter. Is there any other way to use more charecters in tool tip?
Thanks in advance.

Not using the standard shell32 tooltip. I'm afraid that you will have to use a custom tooltip if you require additional features. There are a few articles here on codeproject which could be used.
CPPToolTip v2.1[^]
Custom ToolTips for MFC Projects[^]
