How about:

COleDateTime now = COleDateTime::GetCurrentTime();
now += COleDateTimeSpan(2, 0, 0, 0);

Check if file exist

IS there any way check if file exist without attempting to open the file? Just by looking at directory structure?

I am using MFC and trying to open 2 files simultaneously. Each one can't be open unless the other exist.

Hey all,

I've got a configuration app to write, and I think that the tree/grid control that the VS.NET 2003 IDE uses for Class properties would be a perfect fit. Anyone know what it's called, or where I can find it?

Here's what I'm talking about:

I have made a class and I need to use it's subroutines in another class. How do I make these references?

derive the class from the class that you want to use the member functions is one option.

Depending on the design you can also create an instance of that class whose member function you want to use.

groupbox?->no tooltip?

V.9-Dec-04 3:16

Hello everybody,

I've created a dialog with some controls, the controls show a tooltip when hovered over by the mouse. Now when I put the controls in a groupbox, the tooltip is not shown, the program won't even break in debug into the event handler...

We've tried everything, transparent background, taborder, deriving a class from CStatic and so on...

(I use the ON_NOTIFY_EX message)

I also tried to add the groupbox first to the dialog and then the controls into the groupbox (like VC#), but still nothing.

Can somebody point me into the right direction (article or whatever Smile | :)

)?

thank you very much for your help.

This same thing happened to me because the group box was obscuring the controls. In times past I've always put the group box in front of the controls, but now I put it behind the controls so that tooltips will work. Why this does not work for you is unclear. Have you examined the dialog template in the .rc file to make sure all of the controls are in the order in which you think they are?

do you mean the resource nr associated with the control name? Yes I did, else I don't really understand what you mean. Blush | :O

I was now looking in the direction of the z-order (SetWindowPos), but I don't seem to be able to understand really how it works (my control just dissappaers, which isn't my purpose)

tnx for the reply though.

I'm not sure what "nr" means in this context, but your project should have a .rc file in it. In that file is the dialog's template. Instead of:

IDD_REPORT_SPLFILE_PAGE_PROP DIALOGEX 0, 0, 297, 201
CAPTION "Page Selection"
FONT 8, "MS Sans Serif"
BEGIN
    CONTROL         "&Selection based on text",IDC_XB_SELECTION,"Button",
                    BS_AUTOCHECKBOX | WS_TABSTOP,17,7,149,10,0,
                    HIDC_XB_SELECTION
    LTEXT           "Location:",IDC_STATIC,13,19,50,8
    CONTROL         "S&earch entire page",IDC_RB_SEARCH,"Button",
                    BS_AUTORADIOBUTTON | WS_GROUP,19,30,125,10,0,
                    HIDC_RB_SEARCH
    LTEXT           "&Line number position:",IDC_STATIC,31,59,112,8
    EDITTEXT        IDC_EB_LINEPOS,146,56,40,14,ES_AUTOHSCROLL,0,
                    HIDC_EB_LINEPOS
    CONTROL         "Spin1",IDC_SPIN_LINEPOS,"msctls_updown32",
                    UDS_SETBUDDYINT | UDS_ALIGNRIGHT | UDS_AUTOBUDDY | 
                    UDS_ARROWKEYS,186,56,10,14
    GROUPBOX        "",IDC_GRP_SELECTION,7,7,283,106
    ...
END

change it to:

IDD_REPORT_SPLFILE_PAGE_PROP DIALOGEX 0, 0, 297, 201
CAPTION "Page Selection"
FONT 8, "MS Sans Serif"
BEGIN
    GROUPBOX        "",IDC_GRP_SELECTION,7,7,283,106
    CONTROL         "&Selection based on text",IDC_XB_SELECTION,"Button",
                    BS_AUTOCHECKBOX | WS_TABSTOP,17,7,149,10,0,
                    HIDC_XB_SELECTION
    LTEXT           "Location:",IDC_STATIC,13,19,50,8
    CONTROL         "S&earch entire page",IDC_RB_SEARCH,"Button",
                    BS_AUTORADIOBUTTON | WS_GROUP,19,30,125,10,0,

    CONTROL         "Spin1",IDC_SPIN_LINEPOS,"msctls_updown32",
