What is the actual value of hr?
That aside, why is the service itself not checking for the existence of the file?

The value of HR is -2147221164 which seems to be related to a Class not being registered. But this is confusing as the same files work on an NT box without any problems. I have MDAC 2.8 loaded as well.
The service does do the checking for the existence of the file within the procedure checkForFile. It calls the VB DLL to then take the file, which is zipped up and extract it out and then load into an Oracle database. It's just that when the development was done for this (about 3 years ago) the extraction and loading of data into an Oracle DB was done in VB, and the people who were able to write service code at the time produced it in C++, so we had to ensure that the VB could get called from the service.

Right. Have you registered the VB DLL (using regsvr32)?

Yep I have. I have created an unregister and register command file that calls regsvr32.

I am using CFileDialog for a "save as" where I have to choices for file types: All Files or Avi Files.
I just noticed something very strange and wondered if anyone else has seen the same thing, or better knows how to fix it.
First of all, the "save as" function is done correctly, so 99% of the problem is solved.
It comes up with All Files and indeed shows all files. The problem comes when I change to show only avi files. The window goes blank. If I go back to all files, it stays blank. Only if I choose a different folder is it refreshed properly (with either all or avi files).
I tried it in Paint and there if you change the file type, the window refreshes correctly. In CFileDialog it doesn't.
My code is:
CFileDialog filedlg( FALSE, "avi", // default extension
"mip1.avi", // current file name
OFN_FILEMUSTEXIST | OFN_PATHMUSTEXIST | OFN_LONGNAMES,
"All Files (*.*)|*.*|Avi Files (*.avi)|*.avi||", NULL);
Has anyone else seen this, or can tell me what is wrong?
Thanks,
Ilan

Try using the following code - it should work just fine. Good luck!
CFileDialog filedlg( FALSE, "avi",
"mip1.avi",
OFN_FILEMUSTEXIST | OFN_PATHMUSTEXIST | OFN_LONGNAMES,
"All Files (*.*)\0*.*\0Avi Files (*.avi)\0*.avi\0", NULL);
|

Thanks for the suggestion, but it doesn't work. When I use \0 in place of |, it kills the functionality. Even All files don't appear properly.
I'm going back to what I had since that works much better.

Strange.
Is this the same in Release and in Debug ?
Do you have the same problem if you have more than two filters (try adding an Mpeg Files (*.mpeg)|*.mpeg ?
What if you exchange All Files and Avi Files in the string (so that the default extension is also the one that comes as forst in the string ) ?
~RaGE();

That was a great idea to try the Release as well as the Debug. I didn't think of that.
Unfortunately, it also has the problem in Release.
I also added mpeg and it indeed gave me 3 choices as expected. Still the refresh problem is there.
I looked in a couple of other programs I have and the problem exists there as well. I just never noticed it until today. Maybe it is connected to .NET which I added fairly recently? Hard to believe, but who knows. It is strange that I never would have seen this before.
BTW, I have an avi file in the directory, so even if I put avi files first I will still see them properly. It is only when I pull down the combo box and change the file type that the refresh fails. I'm really stuck as to why.

Unbelievable, it is the .NET!
I can compile without it so I did so.
Without .NET it works like a charm.
I'll bet this is a bug Microsoft doesn't know about.

Just out of curiousity: does the behaviour remain if you set the OFN_EXPLORER flag as well?
I'm thinking about some events that does not occur if the OFN_EXPLORER flag is omitted, e.g. OnTypeChange.

It's supposed to be hard, otherwise anybody could do it!

That was an idea worth investigating. It turns out that OFN_EXPLORER has no connection to the problem. I added the flag and it works correctly when "Use managed extensions" is No and incorrectly when it is Yes.
Now I have complete control of when it appears. Unfortunately, in the real world I need managed extensions since I use the .NET, but at least I know where the problem is. That is more than I knew when I started to ask questions on the board.
The bottom line: the code project is very useful....

Is this a Managed C++ question? If so, have you tried here?

Now, thanks to this board, I know it is a problem with managed extensions. When I started, it never occured to me that the problem could be there.

Your code snippet works fine for me.
What happens if you use GetOpenFileName() instead?

Thanks. Look above. It is the .NET which is causing the problem.

How so? I have v1.1 of the .NET Framework installed.

Did you see my reply to Roger? I have COMPLETE control of when it happens, just turn on or off managed extensions and Voila!

Hi IlanTal,
your code worked.
Whats problem?

Likewise, thanks. It is .NET. Look above on the board.

I have a string input by user and one Static Text on Dialog.
How can i display string in Static Text as long(as many characters) as much that not exceed Static Text length on Screen.
Thanks

what do you mean by this ?! 
if you want to put some string in your static control, you can use something like this :
((CStatic*)GetDlgItem(IDC_MY_STATIC))->SetWindowText("new string");
|
|
|
|
|
an example:
user input 1000 characters.and i have to display it on Static Text in a Dialog.
I now use:(IDC_INSTALL_DES_FOLDER:Static Text)
CSize szTextSize;
CRect rect;
GetDlgItem(IDC_INSTALL_DES_FOLDER)->GetClientRect(&rect);
int i= 0;
MapDialogRect(rect);
::GetTextExtentPoint32(dc.m_hDC, m_strDesFolder, m_strDesFolder.GetLength(), &szTextSize);
while (szTextSize.cx > rect.Width() - 180)
{
::GetTextExtentPoint32(dc.m_hDC, m_strDesFolder, m_strDesFolder.GetLength() - i, &szTextSize);
i++;
}
if (i != 0)
{
m_strDesFolder.Delete(m_strDesFolder.GetLength() - i, i);
m_strDesFolder += _T("...");
}
but when user put something like abcssssssssssssssssssssssssssss...(ex 100 s character)
it work not well

Are you trying to resize the static control depending on the text it is to display? If so you can use the DrawText function to calculate the rect for the text and use this to then create the control.

GetDlgItem is not a nice way of doing it ,control variable should be more fine,<imho>
