Could you explain your problem a little more clearly? What do you mean when you say the line is drawn on the backsite of the window? Did you open your monitor to see if a line was there?

I want add buttons to toolbar dynamicly, also delete them dynamicly.
when I added button to toolbar, the button is gray,,
How can i make the newly added buttons active or avalible to the click command, so that i can use the buttons to control something i want.

Did you set the button state? In the fsState member of TBBUTTON structure, you might need to set the TBSTATE_ENABLED state also.
It also depends on whether you are using MFC or not.
this is this.

Add a handler function prototype in CMainFrame or the class which will handle the click like:
afx_msg void OnSome();
Also in the .cpp file, add this to the Message map:
ON_COMMAND(ID_SOMETHINGELSE,OnSome)
Also define ID_SOMETHINGELSE to be the same as the command-id of the button for which you want to handle the click.
Then send message:
SendMessage(WM_COMMAND,MAKELPARAM(ID_SOMETHINGELSE,0));
//If sent from the same class as the handler.
Also define the function in the .cpp file:
void CClassname::OnSome()<br />
{<br />
}
this is this.

The problem is :when i create a button in toolbar,i got the ID of the button,but how can i make the buttons recieve the click event ?
with the classwizard we can map the command to the buttonID,when i click the buttons,handler fuction is called...
however,now ,the buttons is created dynamicly,and we don't know the buttonID in advance.The classwizard can't work in this case.
i can call the PostMessage() fucntion to inform the buttons created dynamicly. the problem is how can the buttons recieved the click event and
where do i place the message handler fuctions?

Have you add this macro to the map
ON_COMMAND(ID_BUTTON, OnClickButton)
?
or
ON_COMMAND_RANGE
if you have more ID/buttons dynamically created
?
Have a nice code day

_Russell,I add the ON_COMMAND_RANGE macro ,,it works...
Thanks a lot!

Hi bruspark
I think
if your buttons are gray you need to functions for button and check Id from Buttons
|
|
|
|
|
When you created the toolbar and filled in the members of the TBBUTTON struct, you can set the initial state of the button. You should use TBSTATE_ENABLED to enable them and 0 to gray them. You can then use the TB_ENABLEBUTTON message to programatically enable/disable the buttons.
To show and hide buttons you can use the TB_HIDEBUTTON message.

Maybe the whole toolbar is disabled : MyToolbar->EnableWindow(TRUE);

Hi all,
Can anybody help me to reposition the default tooltip that is shown by a treectrl when the item text is clipped inside the ctrl?
I simply want to avoid the clipping of this tooltip when the ctrl is near to right edge of the screen. In this case the default tooltip is clipped by the screen. So I want to move it to left to avoid this clipping.
For example, the treectrl of the workspace in VC-6 IDE is doing the same. If we placed the worksapce toolwindow to right, the tooltip will not go outside of the screen.
Thank you.
