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.

I have added BN_CLICKED message handler also earlier only But it the button is not enabling.other controls like edit Box,Combo Box etc are enabled.But only the buttons are not enabled.
Thanks

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...
virtual BOOL OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo);
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.

you can write ON_COMMAND_RANGE, if creating dynamic controls!

I want to do some modifications to this project.
The modification that I want to do are change the way of taking data, I want to get numbers and not blue or red dots and I do not have any idea how change it, even with the source code. So please help me
|
|
|
|
|
I want to change my project also. I don't want it to work on the computer anymore, I want it to come out. Can you show me how?
Do you know what I'm talking about?
|
|
|
|
|
Can you be more specific.
|
|
|
|
|
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....

First of all I must say one thing your code isnt good you used of TetOut repeated but you can use from a function and in this function insert Textout.This function needs to input parameters for TextOut.How do you refresh this window did you try with Invalidate
|
|
|
|
|
use CWnd::Invalidate() or CWnd::InvalidateRect .

I have been reading and analyzing various progs dealing with DLL's, looking up things in manuals until I understand what is happening. I have encountered the term WINAPI in one prog that used explicit linking to the DLL. There are references in MSDN, but no explanation. (Just its appearance in code snips.) For example, what does WINAPI do in the following:
typedef INT (WINAPI * lp_ptRegisterCallback)(INT callbackID, ProcAddr CBackProc);
|
|
|
|
|
WINAPI is defined as __stdcall (a calling convention). Basically it tells the compiler what sort of function it is, in particular about the arguments passed into a function and who is responsible for cleaning the stack (the function or the caller). Try searching for terms such as "calling conventions" to get a better idea.
