Or, does a Modeless dialog run on a separate thread or process?

The modeless dialog doesn't run in a separate thread. It will act like a window created with CreateWindowEx(), so it usually uses the message loop that the rest of your application is using.
This means you shouldn't have any lengthy processing in your modeless dialog, as both the dialog and the parent window won't be able to handle messages eg. paint the window.

Hi again
I found an odbc library that i think it would be very helpful for me to connect to my db. Before using it i need to do the following. I dont know how to link my project to the library. can anyone explain to me how to do this in VC++.
To use this DLL library in your projects, you will have to include a header file DataLayer.h and copy the compiled module named DataLayer.dll where your executable output is. Or, you can copy it to the Windows folder. Anyhow, now you will be able to instantiate some (but not all) classes from the DataLayer library. The last thing you should do is link your project to the static library DataLayer.lib
Thanks a lot

From the docs...
OnUpdate:
Called by the framework after the view’s document has been modified; this function is called by CDocument::UpdateAllViews and allows the view to update its display to reflect those modifications. It is also called by the default implementation of OnInitialUpdate.
The default implementation invalidates the entire client area, marking it for painting when the next WM_PAINT message is received. Override this function if you want to update only those regions that map to the modified portions of the document. To do this you must pass information about the modifications using the hint parameters.
OnDraw:
Called by the framework to render an image of the document. The framework calls this function to perform screen display, printing, and print preview, and it passes a different device context in each case. There is no default implementation.
You must override this function to display your view of the document. You can make graphic device interface (GDI) calls using the CDC object pointed to by the pDC parameter. You can select GDI resources, such as pens or fonts, into the device context before drawing and then deselect them afterwards. Often your drawing code can be device-independent; that is, it doesn’t require information about what type of device is displaying the image.

so Onupdate must be calling ondraw since it displays data on the screen . AM i right?

True. That is how Document view architecture works!
Document holds the data that will be represented by the view. If the data changes (i.e. the document changes) the view must reflect the changes.

In the definition of your dialog (the .h file), include a CFont object (m_font). Initialise that font object in your constructor:
LOGFONT lf;
NONCLIENTMETRICS ncm;
ncm.cbSize = sizeof(ncm);
VERIFY(SystemParametersInfo(SPI_GETNONCLIENTMETRICS, ncm.cbSize, &ncm, 0));
memcpy(&lf, &ncm.lfMessageFont, sizeof(LOGFONT));
m_font.CreateFontIndirect(&lf);
Then in your OnInitDialog, get the CStatic object for the ontrol, and set it's font. Remember, you need to have named the object in the resources something other then IDC_STATIC.
CWnd *wnd = GetDlgItem(IDC_YOURCTRL);
ASSERT(wnd);
if (wnd) wnd->SetFont(&m_font);

Sometimes if i want to set breakpoint to do debbugging,the error will display that "one or more breakpoints cannot be set and disabled"..Wats the reason for this..How can i set breakpoint in my coding...
|
|

|

Because you are trying to put a breakpoint on an invalid line. An invalid line is a line that isn't related to an assembler instruction (like for example declaration of variable, an opening or closing brace, ...)

May be you set the breakpoint on a line which is invalid. Like on an empty line or comment lines.

F9 where you want to set the breakpoint. F9 again on the same line will clear the breakpoint.
To clear all break points in the project press Ctrl+Shift+F9.

or maybe Configuration mode is Release not Debug
|
|
|
|
|
Where is that configuration mode?
|
|
|
|
|
In menu build option configuration manager and see Active solution
|
|
|
|
|
With MSVC6 (and possibly other debuggers) this can happen if you place a BP in a DLL then try to debug an EXE that loads the DLL but hasn't done so yet.
