Somethings seem HARD to do, until we know how to do them.

You should provide event handlers for these buttons, else it will appear disabled.

Hi,
I have declared the following event handler void OnUpdateButton1(CCmdUI *pCmdUI); and i have added the following message map ON_UPDATE_COMMAND_UI(IDC_BUTTON1, OnUpdateButton1)and i have defined the above function as follows,
void CMCDilaogbar::OnUpdateButton1(CCmdUI *pCmdUI)
{
pCmdUI->Enable(TRUE);
}
But i am still getting the button as disabled.How can i move further.

Thanks

Open the dialog bar in resource view. Select the button press Ctrl + W to open the class wizard.

Select an event handler like BN_CLICKED. But make sure that you select the proper mainframe class as the class were you wish to add the event handler. Select Add function. This will add a function to the class. Click on edit code to edit the code for the button.

Now this should enable the dialog bar button. Hope this helps.

Are you adding the event handler to the correct class. For eg: you should add to the mainframe class or to the dialog bar class.

Hi,
I have added the BN_CLICKED message handler in the Dialog Bar class only.But i haven't done this in MainFrame class.Now i have done it.The button is enabled now.

Thanks

There is another easy way of doing this. Just override the following function your derived CMainFrame class and you will have all controls in the dialog bar and tool bar and all menu items enabled without writing event handlers...

// Write this in MainFrame.h
virtual BOOL OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo);
 
// Write this in MainFrame.cpp
BOOL CMainFrame::OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo) 
{
	return TRUE;
}

Well this would enable all buttons and menu items but of course you should write event handlers if you want to have something happen. Smile | :)

you can write ON_COMMAND_RANGE, if creating dynamic controls!

Sure, I want to change de code of the program that i got here, the program is about a Neural Network that recognize patterns based on the number of dots, that you draw in the screen so i want to change that and i want to use numbers as inputs and not the dots

I have a program that I have written in Visual C++ 6.0 that using the textout command for print to the screen. When I initially send text to the screen everything prints. Later I use textout to update the screen but only part of the update is printed or none of it at all.

If I minimize and then maximize my box then all the text that was sent to the screen is printed and everything is at it should be. What am I doing wrong or do I need to do in order to get the screen updated without the minimize and maximize?

Without seeing your code it's hard to say. There could be a number of things going wrong, failing to invalidate the rect, drawing in the wrong place, drawing out of order, handle leaks....
