I am working on MFC SDI Application. I hav attached two dialogs. Both hav one editbox control.
In these text boxes, file names are to be displayed. They can be edited in them as well as browsed using the browse button on the same dialog. Browse button is working.
I also want that, the second dialog, which has the editbox for destination file path , should show the path of the source file, after changing the file extension. how to do it???
Now, the problem is , it es showing "Enter Source File", even if, the source file is already entered.
Thanx for ur valuable time.

How are the dialog boxes displayed? Are they both modeless, or is one modal and the other modeless?

This question leaves a lot to the imagination. What is the "source file" and "file extension" of which you refer?
Explain a bit better as to how these two dialog boxes work in the overall scheme. Do they send information back and forth to each other?

hi!
I read ur reply. following points will clear ur doubts about my application:
Both the dialog boxes are modal.
Then you asked me: What is the "source file" and "file extension" of which you refer?
The extension of source file is .yak. It is an "ini file".
Then the name which has to be displayed in the second edit box will be the same but the extension is changed to ".config".
Then u said: "Explain a bit better as to how these two dialog boxes work in the overall scheme. Do they send information back and forth to each other?"
These dialog boxes don`t send inforation back and forth to each other. But, on clicking OK button in the first dialog box, the second one gets opened, and by default shows the same file name(as was entered in the first one) in the edit box , with the extension changed.
Thanx a lot

Hi,
I have been struggling for some time with a problem experienced by a customer of our product. We have a reporting facility, which allows users to output information to a printer. We have found, on Windows 98, that when a block of text goes over a page, we are losing some text down the gap.
To print the text across pages we are using DrawTextEx, and getting the returned uiLengthDrawn to see how much fitted up to the bottom of a page, so we can continue the text from where we left off. This works perfectly on the screen, and also on NT/XP, but the uiLengthDrawn value is always wrong when going to any printer on Windows 98.
Has anyone else experienced this problem, and if so, do you know of any solution?
Paul.
P.S. It's my birthday today!

do you use MFC? If so, maybe you could use CDC::GetTextExtent(...) to know the size of the text to draw/print? To output text I generally use CDC::TextOut(...) and don't recall having any clipping problem with this method.
(the corresponding win32 api are ::GetTextExtentPoint32 and ::TextOut)

Thanks! 
Using GetTextExtent/TextOut is all very well, but that doesn't tell me how much of my text will fit into a given rectangle. Once I've drawn my clipped text onto the bottom of my page, I need to know where in my text string I need to start drawing on the next page.
(I do use MFC BTW, but I don't think that's relevant.)

Yes, but not directly. GetTextExtent will give you the size required to draw the given text. Knowing where you begin to write the text, you should then be able to say if the text will go outside a given rectangle or not.
IMO? you should use it before drawing. Here's a sample how I use it:
CClientDC dc(this);
CFont *pFont = CFont::FromHandle((HFONT)::GetStockObject(DEFAULT_GUI_FONT));
CFont *pOldFont = dc.SelectObject(pFont);
CRect clientRect;
CSize textSize = dc.GetTextExtent(sTitle);
GetClientRect(&clientRect);
int iWidth = clientRect.Width() - 12;
CString strNewTitle(sTitle);
while(textSize.cx > iWidth){
sTitle = sTitle.Left(sTitle.GetLength() - 1);
strNewTitle = sTitle + _T("...");
textSize = dc.GetTextExtent(strNewTitle);
}

Mmmm. That's what I was afraid I may have to resort to. It's not very efficient for huge chunks of text, which is why I didn't really want to do it this way in the first place (our reports are often very long, with large chunks of text), but I guess I can optimise it by splitting the string up and testing it using a binary method if it's over a certain length. I guess as it's only a problem on Windows 98, I'll just do it this way for that - maybe that'll teach them to use a real(-ish) OS!
Thanks for your time looking at this!
Paul.

Yes, it is probably not very efficient, even if is it plausible it can be improved (using dichotomy seems good, making assumption on font width then on likely text length could perhaps also help).
Limiting this solution to Win98 users, by detecting the OS, could also limit the damage.

Is the problem not occuring on Win95? (I have to deal with this sh*tty OS, some of our customers still use this big bag of #$ù*#.
Also, the problem may come from the implementation of the printer driver on Win9x. Maybe an update of them, with a lot of luck...

Just looked at source for CEditView printing, as suggested by Jack Squirrel in his reply[^], and it seems that MFC uses a similar method, by having a guess, and then adjusting the string until it best fits. They do that for all platforms (MFC doesn't use DrawTextEx anywhere as MFC pre-dates the function). Looks like that's what I'm going to have to do after all  , but at least our customer will be happy!

Yep, avoiding DrawTextEx seems the good thing to do, jack's advice is the good one. I just have a look to CEditView printing too, very interesting. I learned something, there is an undocumented fucntion _AfxClipLine which may be useful sometimes.
Thanks for the feedback!

There's code in the CEditView class that clips/fits text based on a rectangular boundary. Should be a primary function and a couple of helpers - just copy it to your project, tweak it if need be, and away you go.

Mmm. Just looked at that. It uses a method similar to the one I was avoiding  by guessing how many might fit, then decreasing/increasing the length of the string until it fits best. Oh well, looks like that's the way to go.

how do i get the font name used by the system ,or more precisely i need to fill the LOGFONT structure how do i do.
thanx in advance

You can use the ::GetStockObject function.
If using MFC, the code would be
LOGFONT logFont;
CFont *pFont = CFont::FromHandle((HFONT)::GetStockObject(SYSTEM_FONT));
pFont->GetLogFont(&logFont);

 Hello , I am new to MFC.
I am using MS Access database .
I want to get tables list using CDatabase.
Is there ant SQL Query for getting table names from Access database.
I used this code but I am getting errors.
CDatabase db;
CString sDriver = "MICROSOFT ACCESS DRIVER (*.mdb)";
CString sFile= "c:\\mydabase.mdb";
sDsn.Format("ODBC;DRIVER={%s};DSN='MyDsnName';DBQ=%s",sDriver,sFile);
db.Open(NULL,false,false,sDsn);
CRecordset recset(&db);
recset.Open(CRecordset::forwardOnly,sql,CRecordset::dynaset);
CString s=recset.GetTableName();
//int n=recset.GetRecordCount();
MessageBox(s);
========
Here I am not getting table name
Plz Give reply soon .

Does the database and the DSN exist?

It looks like you are trying to create both a DSN and a DSN-less connection. Why?
