Re: How to put a carriage return into a CView object?

5-Jan-04 7:20

Dear all,
How can I output a carriage return character in CView object? I tried the combination of "0x0A" and "0x0D", also "\n" character, but both of them failed. The "\n" character works properly with CRichEditView, but not with CView. How can I solve this problem? Thanks.
Best regards.

What method of the CView class are using in order to output the carriage return character?

Dear Chris,
I used the method TextOut of CDC object got from GetDC().

Have a look at using the DrawText method instead. You call it twice. First to have it calculate the necessary coordinates and then a second time to actually 'draw' the text. The string of characters can contain any kind of control sequences such as HT, CR, and LF.

Thank you very much,
I'm using that method now.

CView knows nothing of any character, let alone CR/LF characters. The reason it works for a CRichEditView is because it is based on an edit control, which knows about lines and such. If you want your text to go to the next line in a CView control, you'll have to manipulate the 'y' coordinate yourself.

If I recall correctly, DrawText() and DrawTextEx() can output multiline text...

Thanks Nick,
You're right, DrawText works better. However, we must specify the LPRECT where the text is showed.

Hi Folks ,
i want to load and display bitmaps in my MFC(CView) derived class.
i have tried quite a bit functions(LoadBitmap () etc..)
but it does not work for me.
plz help me in this regard
thanx in advance

Define "does not work." Are you getting compiler/linker error(s), run-time error(s), or does LoadBitmap() return an invalid handle.

Here is a simple code to load and siplay any bitmap from resource file. d is a pointer to CDC , while IDB_BITMAP1 is name of BITMAP resource which u want to display..

<br />
  <br />
  //d is pointer to CDC<br />
  CDC dc;<br />
  CBitmap bitmap;<br />
  bitmap.LoadBitmap(IDB_BITMAP1);<br />
  dc.CreateCompatibleDC(d);<br />
  d->SelectObject(&bitmap);<br />
  d->BitBlt(0,0,100,100,&dc,0,0,SRCCOPY);<br />

I've only worked with very simple DBs in C++/MFC to date, mostly having 1 table, but I've been having trouble with a 3-table DB for a couple of days. The App Wizard creates one recordset, accessed via m_pSet, which contains all fields from all tables. This opens the recordset well enough, but when I change the m_strFilter value and requery to find a match on fields in just one of the tables I get an error that isn't defined anywhere I can locate (Too few arguments - 2 expected). The requery is the call that causes the error; everything else appears to work fine up to that point.

Would it be simpler (and perhaps smarter) to construct separate recordsets for each table, and do this operation on just the one table? These tables don't have to be joined; it's a very simple DB.

U simply create ur application, without mentioning abt the
database support.
now create a new class whose base class is CRecordset.
and add the following header file #include "afxdb.h"
in the stdafx.h

Before changing the m_strFilter, what has it been set to? I'm thinking that you may be 'breaking' the joining of the tables of the original query. I'm going out on a limb here, but I think you probably need to a new query/recordset together to fit your needs. Typically the requery method is used where you've changed the value associated with parameters and require the recordset to be fill with new data. Since you need to only query one of the tables, I'd recommend building another recordset just for that query.

That's my thinking, as well. When I think of a recordset, I picture something like a spreadsheet that I can scroll thru selecting rows as needed. When the wizard creates the initial recordset, it binds all the fields from all tables, even though one may have a thousand records, and another 6. That's gotta break something. When my requery asks for a record from the one table containing the two fields of interest, there's no guarantee that the other two tables will have anything in that particular row, so something's got to give. Thanks for the tip.

In your CRecordset-derived class, make sure that the value of m_nFields matches exactly the number of RFX_xxx() calls in the DoDataExchange() method (these calls are preceded by a call to pFX->SetFieldType(CFieldExchange::outputColumn)). This number must also match the number of columns actually being retrieved from the SELECT statement.

Now as far as m_strFilter goes, you'll also need to make sure that the value of m_nParams matches the number of '?' in m_strFilter, and that they are in the same order as the corresponding RFX_xxx() calls in the DoDataExchange() method (these calls are preceded by a call to pFX->SetFieldType(CFieldExchange::param)).

It's always better to not add unnecessary complexity to an application. If no JOINing is required, by all means don't do it!

I currently use the Visual C++ .NET 2002 Professional product.

Is it true that compiler optimizations are NOT available in this version??? They do appear to be grayed-out (disabled) in the project properties boxes. Confused | :confused:

PLUS, I'm considering upgrading to Visual C++ .NET 2003 Pro (their newest) BUT will only do so if compiler optimizations are then available. Does anyone know if this will be the case? Confused | :confused:

If I have to buy an "enterprise" version just to get compiler optimizations, I may be kicking the MS development environment off my PC!!! Poke tongue | ;-P

The 2002 Professional product includes the optimizing compiler. The non-optimizing compiler is only shipped with the "Standard" edition, and the .NET Framework SDK.

Same for 2003 versions - "Professional" is what you need.

Which options are greyed out? What type of application are you building (.NET, Windows, .exe, .dll, etc.?)

One other thing - at the command line you can determine if you have the optimizing or non optimizing compiler -- just type cl /? to see the banner. Mine reports:
