What does 'not working' mean ? You get a crash, it doesn't compile, it does not do what you expected (and explain what you expected and what you get instead), ...
We cannot guess what's happening.

Yes, the windows file browsing dialog never appears, focus turns to nothing and the whole application is locking.

Since your application seems to be a non-MFC one, I suppose that CFileDialog does not work because of some missing initialization stuff, required by MFC. Maybe you should call AfxMainInit once in your DLL?

The variant without MFC, based on GetOpenFileName, probably requires a previous call of InitCommonControlsEx initialization function.

Basicly what i've done:
Use the WTL Project Wizard to create a DoModal Dialog based application, replaced _tWinMain with DllMain, and set the file output type to DLL

GetOpenFileName actually returns a BOOL value, not a code which can be compared with IDOK. I think you should use a simple if. If it returns FALSE, you can see what is the problem using CommDlgExtendedError:

if(GetOpenFileName(&ofn))
{
    SetDlgItemText(IDC_EDIT1, ofn.lpstrFile);
}
else
{
    DWORD error = CommDlgExtendedError();
}

Then investigate the error code, or tell us.

This might be the problem normally we specify the filter as follows (seperated with "|" and ends with "||"
e.g

char* pszeFilter = "*.*|*.*|text|*.txt|Music|*.mp3||";

The separator depends on approach used. If the filter is set in OPENFILENAME structure directly, then '\0' must be used. If the filter is set in the constructor of CFileDialog object, then '|' is used. CFileDialog will convert it to '\0'.

Is there a possibility to create a datetimepicker in a dialog without days (only with month and year)?

Thanks, Gerhard

Not without Owner/Custom draw.

You know you're obsessed with computer graphics when you're outside and you look up at the trees and think, "Wow! That's spectacular resolution!"

Sounds complicated, so I will look for another way to enter month and year.

If you are interested try a custom control, using COleDateTime class. Smile | :)

Hallo,

But some things are HARD, even you got an answer that seems to be the solution.

I made my dialog with the wizzard and got a diaolg.cpp with a DoDataExchange-function like this:

DDX_DateTimeCtrl(pDX, IDC_DATETIMEPICKER1, m_begin);

m_begin is a COleDateTime-variable. But where and how do I have to place your Set.Format-code? I tried it with IDC-DATETIMEPICKER1 in an OnInital-function , in a PRECREATE-function, I tried it with the m_begin-variable, nothing works.

Thanks in advance, Gerhard

m_begin should be a control variable for the date time picker control .
Right click on the datetime picker contrl > add variable m_begin

in on initdialog use
m_begin.SetFormat()

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

Hallo,

That works wonderful in my dialog, but I have a last problem. How can I get the valus of year and month at the end of the dialog. What I did till now was:

year.Format("%i", dialog.m_begin.GetYear());
month.Format("%i", dialog.m_begin.GetMonth());

And that doesn't work any more Sigh | :sigh:

year and month are CStrings, but would not be a probelm if it would be int ore something other.

It's like it is always - the solution of one problem results in another problem Cry | :((

Thanks - Gerhard

Check out Creating a Time Picker with no Seconds Field[^] - you can use a similar technique to change the date format that the DTP control shows

From where you got the values of point? They should be in screen coordinates.
