Hello. I'm using MFC without the use of any wizards or such (VC6/w2kpro), doing everything manually. Now I've run into a problem, I cant set message text to my status bar..here's my frame window constructor:
FrameWindow::FrameWindow()
{
Create(); // create the frame window
m_wndStatusBar.Create(this);
SetMessageText("Testing");
}
When I run this code, I see the status bar, but I don't see any text on it. Then I tried moving SetMessageText("Testing"); to FrameWindow::OnPaint(), and then the text appeared. Now, I dont want to call SetMessageText() in OnPaint(). Why can't I set the inital text in the frame window constructor?
I also tried with m_statusBar.GetStatusBarCtrl().SetText( "Testing", 255, 0 );
Same result as with SetMessageText().
Please help me solve this annoying problem

Probably, it does not work that there are no created fields in SB. Try to use something looks like that:
... It's our SB fields
static UINT indicators[] =
{
ID_SEPARATOR, // status line indicator
ID_INDICATOR_POS,
ID_INDICATOR_CAPS,
ID_INDICATOR_OVR,
ID_INDICATOR_NUM,
ID_INDICATOR_SCRL,
};
... Use update action handlers to change contents of SB
ON_UPDATE_COMMAND_UI(ID_INDICATOR_POS, cmdupOnIndicatorPOS)
ON_UPDATE_COMMAND_UI(ID_INDICATOR_OVR, cmdupOnIndicatorOVR)
....
..... After SB creation we must set indicators
pStatusBar->SetIndicators(indicators, sizeof(indicators)/sizeof(UINT));
...... Update it!!
void CSourceView::cmdupOnIndicatorPOS(CCmdUI* pCmdUI)
{
TCHAR str[32];
....
sprintf(str," Line %d, Col %d", dwLine+1,dwCol+1);
pCmdUI->SetText (str);
}

Tried your suggestions (except for the command handlers), still no text in the message pane. And I don't think the lack of panes was the problem, since text appears if I call SetMessageText() in OnPaint() of the parent window (the frame window). I've made a small test program: which is as follows:
///// APPLICATION.H /////
#ifndef APPLICATION_H
#define APPLICATION_H
#include <afxwin.h>
#include "FrameWindow.h"
class StatusBarApplication : public CWinApp
{
public:
BOOL InitInstance();
};
extern StatusBarApplication g_applicationInstance;
#endif
//// END OF APPLICATION.H ////
//// APPLICATION.CPP ////
#include "Application.h"
StatusBarApplication g_applicationInstance;
BOOL StatusBarApplication::InitInstance()
{
m_pMainWnd = new FrameWindow();
m_pMainWnd->ShowWindow( m_nCmdShow );
m_pMainWnd->UpdateWindow();
return TRUE;
}
//// END OF APPLICATION.CPP /////
//// FRAMEWINDOW.H /////
#ifndef FRAMEWINDOW_H
#define FRAMEWINDOW_H
#include <afxext.h>
#include <afxwin.h>
class FrameWindow : public CFrameWnd
{
public:
FrameWindow();
DECLARE_MESSAGE_MAP()
private:
CStatusBar m_statusBar;
};
#endif
//// END OF FRAMEWINDOW.H ////
//// FRAMEWINDOW.CPP ////
#include "FrameWindow.h"
BEGIN_MESSAGE_MAP( FrameWindow, CFrameWnd )
END_MESSAGE_MAP()
static UINT indicators[] =
{
ID_SEPARATOR, // status line indicator
//ID_INDICATOR_POS,
ID_INDICATOR_CAPS,
ID_INDICATOR_OVR,
ID_INDICATOR_NUM,
ID_INDICATOR_SCRL
};
FrameWindow::FrameWindow()
{
Create( NULL, "Status Bar Test" );
m_statusBar.Create( this );
m_statusBar.SetIndicators( indicators,
sizeof( indicators ) / sizeof( UINT) );
SetMessageText( "test" ); // No text appears in the message pane
// despite this call.
}
//// END OF FRAMEWINDOW.CPP ////

What about CStatusBar::SetPaneText??? In my opinion it is best solution...

I am retrieving a text field from a database using the syntax that works fine for an ordinary text entry:
m_photoInfo = (_bstr_t)m_pRecordset->Fields->GetItem ("ID")->Value;
the problem here is that in the ID field I have a value C:\def.mdb,abc
When it gets this value out I have a messagebox pop up which tells me its horribly confused and has some garbage characters ef.mdb,abc
How do I get this text value out so that it comes out properly?
Thanks,
ns.

how are you displaying your message box?
are you using a function that uses printf()-style formatting??
strikes me that whatever code you're using is trying to interpret "c:\def.mdb,abc" as a format string, thus it's got a "\d" in the middle of it.
Experiment: manually update your record in the db so that the value is "c:\\def.mdb,abc" and see if it displays properly.

I made a database class and the Open() function is quite flexible but opens a recordset based on a specific query. Its too involved to remove that inflexibility. Now I am wanting to use my database class but open with a whole different query. SO is it okay if I have a function called DbClass::Open2() which opens a database based on my new specific query (I may make Open2 be able to take any query but for the moment not). then when I want to open a database with my new query I can instantaite a new db object and call its open2 which in no way will interere with the db object which called Open1 (the original).
Any comments? I know this is not good programmmming but do you agree that I can call two different versions of Open if I so desire...
Thanks,
ns

Just call it Open but use different parameters. C++ will be able to figure it out. Its called method overloading.

void MClass::Open()
void MClass::Open(int i)
void MClass::Open(char c)
Are different functions of the same class with the same name but having different parameters. This is called function overloading.

Why not rename Open to something more descriptive and change our code? Then add another function for your 2nd query.
Use something like QueryCustomers and QueryProducts instead of Open and Open2.

Good idea! I'm just so glad I could extend my class. Appreciate your advice.

If you are refering to the app that is launched when you get an error and you tell it to debug, look up AeDebug on MSDN. Its a registry entry.

1.
I've CEdit and a CButton on a CDialog. The CButton placed on top of the
CEdit. When the CButton is dragged up/down, I wish the CEdit will
streach/shrink, corresponding to the CButton bottom coordinate.
CAN SOMEONE LINK ME TO SOME ARTICLE THAT CAN RESOLVE MY ISSUE

use ownerdraw buttons for non-rectangular buttons and use WinAPI functions
CreatePolygonRgn
SetWindowRgn
etc.
for creating windows with arbitrary shape

quick, easy question:
how do I merge two std::set<ulong> sets into one?
for example:
std::set<ULONG> Aset;
std::set<ULONG> Bset;
...
...
...
...
Aset.merge( Bset );
I'm guessing I don't have to do it by hand (iterate BSet, adding all elements to ASet).
TIA,
Pete

use std::copy with a back_inserter, I would have thought.

Didn't work, but that could have been me calling it wrong.
I ended up doing it by hand:
for( set_it = Bset.begin(); set_it != Bset.end(); set_it++ )
Aset.insert( set_it );
which does the job I guess...
Thanks anyway Christian

The standard, (and perhaps, the most common) way seems to be that if you want to create a bitmap button, you'd embed a CMyBitmap class object inside the view or the dialog, and from inside the definition of CMyBitmap you'd use LoadBitmapEx to load the bitmap, followed by using the SetBitmap function from CButton. (At least that's how I have been doing it.)
Then, I discover this book where the author totally seemed to avoid that path, and instead, embedded a CBitmapButton object inside the dialog, called Autoload from inside OnInitDialog to load his bitmap, and that was it. It worked!
However when I tried to emulate his technique, I have no success story to deliver. I didn't work for me.
Does anybody know what the author may have done to make his technique work, but didn't for me?
His name is Keith Bugg, and the book is, "Building Better Interfaces with MFC." His sample was part of Example 1.
Thanks.

is this anything like the CBitmapButton class that comes with MFC ?

Yep. But it's pretty clunky, um... basic.

Interestingly, David Kruglinski, George Shepherd and Scott Wingo, on page 264 of their book, "Programming Microsoft Visual C++: Fifth Edition" shows something similar to what the other author whom I was talking about, had done.
CBitmapButton m_editCopy;
CBitmapButton m_editCut;
CBitmapButton m_editPaste;
BOOL CAboutDlg::OnInitDialog()
{
CDialog::OnInitDialog();
Verify(m_editCopy.AutoLoad(IDC_BUTTON1, this));
Verify(m_editCut.AutoLoad(IDC_BUTTON2, this));
Verify(m_editPaste.AutoLoad(IDC_BUTTON3, this));
return TRUE;
}
And they showed an illustration of a dialog window with the three Bitmap buttons. It obviously had to work for them also.
It got to be something else that they are doing, because the technique is not working for me.

When I double click on a file whose extension is handled by my MDI app, it starts to run the app but doesn't show the MainFrame properly (the floating dialogbar appears, but no main window or anything).
I get an error saying "Cannot find the file ... Make sure the path and filename are correct and that all required libraries are available."
I think these might be two separate problems, because when I click OK on the error message the half-opened application remains.
The same thing happens when another instance of the app is running. I'm not trying to do anything tricky here, like open the file in the same instance, which just seems too difficult. I've found similar postings on this forum but nothing that helps here.
thanks,
Jake
