I'm going to try overriding CWinApp::OnFileNew, that should do it.
Thanks for trying.

Returning FALSE from CDocument::OnNewDocument() will also do it.
You may be right
I may be crazy

Also, returning FALSE from a PreCreateWindow() override will prevent the creation before the
associated HWND is created.

I didn't know that. I'm going to have to look into that - if it's MDI-specific maybe(?)
Thanks!

It looks MDI specific but I suppose you could use OnFileOpen for SDI.

How to catch WM_CHAR ,WM_KEYDOWN in Dialog Base.
|
|
|
|

In MFC, by using The On*() handlers, or using PreTranslateMessage(...) from within the CDialog class. In straight C/C++, by adding the message identifiers to your message pump.
Many examples on this site catch those messages - if you do an article search for those messages, I am sure you will find matches.

I've looked around but I think I'm looking for the wrong things because I instinctively feel there must be a very, very simple way for me to make a DateTimePicker control on a simple MFC dialog automatically update the current time (and maybe date in another control). I don't mind following an article if you point me there

You mean like you read the data from the source control and you write it to the target control? That is very simple.

what source control? I want it to display the current time, but I am getting confused about the formats. I have a DateTimePicker control, but have seen documentation for a DateTime control. I've seen where you can send a SetTime message with CTime, but the control I'm using has SetTimer not SetTime. I think I'm just getting mixed up. I've dropped a picker onto my dialog, set it to display in time format, I just want that to update every second with the real time.

Get the current time using GetSystemTime(). That result is your source data. Then write that data to the DateTimePicker control.

I realise I'm not at your standard, but are you meaning to take the mickey by just repeating my question? Obviously if I'm asking how to update a datetimepicker control I would do it, so telling me to get the current time and update the control is not an answer.
There is no SetTime function for my control. Maybe this is why I am getting confused. I am expecting to see a SetTime function, but I only see SetDlgItemText. Perhaps I need to pass in a pointer to GetSystemTime, then use that somehow formatted to pass to set the control text, but that wasn't what I was expecting, I now see I also need a timer event

Are you working from a book or tutorial? If not you should be. You should aquire some basic knowledge before posting questions here. Trying to use a forum to get people to teach you basic programming constructs is not going to be productive.

Have you set up a timer by calling SetTimer(1000)? In response to the WM_TIMER message, update the control with the current time.

Hi David,
I'm only used to knocking out dialog apps with the MFC app wizard so am just a bit unsure where to put the timer in, and whats the proper syntax (and where to put it) for a function that the timer calls etc.
any tips or links to external tutorials?

A common place to call SetTimer() is in the OnInitDialog() method.

yep, I thought as much, it was the function that settimer calls I was unsure if it was just a function you can slap anywhere, or does it need to be "tied in" somehow to the appwizard generated stuff with the message maps and stuff.

Revisit the link I provided. It shows how to call SetTimer() and how to respond to the WM_TIMER message.

Hello,
I would like to get the size of un array of strings that I pass as paramater to a function but I am not comfortable with pointers.
could you please tell me what I did wrong with this code?
extern const char* test[] = { "Data", "Data","Data","Data", "Data","Data", "Data", "Data"};
int MyFunc(const char* test[])
{
int size = sizeof(list) / sizeof(list[0]);
return size;
}
int sz = MyFunc(test) // return 1 instead of 8
|
|

C arrays are not arrays they are pointers, therefore there is no way to determine size.

Hi,
thanks for reply.
I'm afraid the problem is elsewhere.
If I bring const char* test[] into the function (no extern declaration) I get the right size.
I think that i do something wrong with the function's parameter.
Any idea?
int MyFunc(const char* test[])
{
const char* test[] = { "Data", "Data","Data","Data", "Data","Data", "Data", "Data"};
int size = sizeof(list) / sizeof(list[0]);
return size;
}
int sz = MyFunc(test) // It works , return 8

Unless list is defined elsewhere, how are you not getting a compiler error here?
