If I understand it right, you want to redo something similar? WTF | :WTF:

Why would you do it, when somebody has already done it? The classes I linked you to are built very well, presented to the community and are already being used by people.

I suggested you to use it because it will enable you to build a more friendly and more easily manageable user interface. If you are worried only because your application is cluttered with lots and lots of dialog boxes and you don't know how to manage them together, then CTreePropSheet or CTreePropSheetEx are very good options.

I'll maybe import this if there is really no other possible way.

You see, there's a thing called code-reusability, which is one of the major advantages of OOP. Why don't you take full advantage of that? Making use of those classes will do good for you, because you are with a typical problem of having lots of dialogs and you don't know how to mend them together. By using either of those classes, you could also group dialogs that are closely related into a category. By all means, I will suggest you to at least try either of those classes once.

no, actually I want to find another option or another way that I can do. Like I am reading about design patterns and looking for one that could be applicable to this problem. Sorry if I might have not clearly explained myself well. I appreciate that I now have one possible solution which is the CTreePropSheet but I just want to know if there would be other solutions. Certainly I won't attempt to redo this, unless I have lots of time, knowing it's already proven and tested by the community.

Thanks and I will try this first thing tomorrow. But even with this, I would still like to know if there are any other possible solutions to my problem. greatly appreciate it. thanks. Smile | :)

CFileDialog

Hi I'm Rathakrishnan. I have created File Save Dialog using MFC. The code is,

void CPerspectiveDoc::OnFileSave()
{

if(CurrentPath == "Untitled.vps")
{
char acFilters[] = "VPS files (*.vps)|*.vps||";
CFileDialog filedialog(FALSE, "vps", CurrentPath, OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,
acFilters);

if(filedialog.DoModal() == IDOK)
{
CurrentPath = filedialog.GetPathName();
JustPath = CurrentPath.Left(CurrentPath.ReverseFind('\\')+1);
}

}
The Save as Type Combo Box contains only "VPS FILES(*.vps)" string. Now I want to add this string also to the Combo Box ("NIF FILES(*.nif)). How can I do this?

Just change your filter:

char acFilters[] = "NIF Files (*.nif)|*.nif|VPS Files (*.vps)|*.vps||"<div style="display:none;" class="CPhogPost"></div> 

<div class="ForumSig"></div>

No. Changing the filter alone as u said is not working. What else can we do?

Please elaborate me on what you mean by "not working"?

The string "NIF files (*.nif)" was not displayed in the Save as type Combo Box. What to do?

Show me the code.

This is the code.

void CPerspectiveDoc::OnFileSave()
{

if(CurrentPath == "Untitled.vps")
{
char acFilters[] = "VPS files (*.vps)|*.vps||";
CFileDialog filedialog(FALSE, "vps", CurrentPath, OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,
acFilters);

if(filedialog.DoModal() == IDOK)
{
CurrentPath = filedialog.GetPathName();
JustPath = CurrentPath.Left(CurrentPath.ReverseFind('\\')+1);
}

}

What a waste of time! You haven't added the new extension to the filter! Indeed, this code will be "not working".

Sorry.I undo the extension. Here is the new code. This also not working.
void CPerspectiveDoc::OnFileSaveAs()
{

char acFilters[] = "NIF files (*.nif)|*.nif|VPS files (*.vps)|*.vps||";
CFileDialog filedialog(FALSE, "vps", CurrentPath, OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,
acFilters);

if(filedialog.DoModal() == IDOK)
{
CurrentPath = filedialog.GetPathName();
JustPath = CurrentPath.Left(CurrentPath.ReverseFind('\\')+1);
}

CDocument::OnSaveDocument((LPCTSTR)CurrentPath);
SetTitle(CurrentPath);

}

What is CurrentPath ? This works for me:

char acFilters[] = "NIF files (*.nif)|*.nif|VPS files (*.vps)|*.vps||";
CFileDialog filedialog(FALSE, "vps", "hello", OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,acFilters);
filedialog.DoModal();

hi...
i was declared as
_variant_t vc;
FieldPtr fieldpointer;

but the error is
_variant_t undeclared identifier.
FieldPtr undeclared identifier.

should i add any header file?

i think this is a silly question.
but sorry... i don't know.

There lies the problem, you should have declared yourself as "real".

_variant_t is defined is comutil.h
and
You should import <msado.dll></msado.dll> before using FieldPtr
