Can someone remind me what the required step is so that if you add in a header and source file from an article here to be included in your project (eg MFC dialog), you get the class members to pop up when you hit a "." or "->" operator on an object.

Nothing special is required. You may need to rebuild the .clw file, however.

hmm, I tried this but no joy so far. I've added Cedric Moonens CCHartCtrl files to my project and make use of them on a dialog with a graph. I know it all works properly, but for example where I have
CChartSerie* pLineSerieCol = m_ChartCtrl.AddSerie(CChartSerie::stLineSerie);
pLineSerieCol->SetName("Energy Data");
pLineSerieCol->SetColor(0x00ff0000);
at the "->" it refuses to pop up the available methods of the class. I've manually deleted the .clw file, tried rebuild all and also opened class wizard with the clw file missing to force it to rebuild and checked that the source files are all included, but no joy as yet.
I wonder if it is humanly possible to feel more like a muppet than I do today

I've had this happen in a few instances where the method that I was currently in had not yet been added to the class. For example:
void MyClass:DoSomething( void )
{
CChartSerie* pLineSerieCol = m_ChartCtrl.AddSerie(CChartSerie::stLineSerie);
pLineSerieCol->SetName("Energy Data");
pLineSerieCol->SetColor(0x00ff0000);
}If the DoSomething() method had not yet been added to MyClass, then Intellisense would fail to work. This does not appear to be the case with you however.

The default setting in IDE in VS2005 while creating a new project to Use Unicode Character Set. There are several functions that use TCHAR and the _T macros. Why is is that the default setting is set to unicode. Most of the applicaitons are written in such a way that it expands to unicode or single byte character set while _MBCS is defined.

hi im trying to get my head around GDI+ as far as i can tell i can only use it in the main function.
With what i've done below the image shows up at first but when the window refreshes i.e (change the size of it)
the image disappears is not repainted.
main..
GdiplusStartupInput gdiplusStartupInput;
ULONG_PTR gdiplusToken;
GdiplusStartup(&gdiplusToken, &gdiplusStartupInput, NULL);
{
Graphics graphics(GetDC(hwnd));
Image* image = new Image(L"clock2alpha.png");
Bitmap bitmap(L"clock2alpha.png");
graphics.DrawImage(&bitmap, 0, 0);
}
GdiplusShutdown( gdiplusToken );
.....
im interested in displaying png images and how to access them outside the main method with GDI+
thank you

Because your code doesn't have a re-painting mechanism. The drawing code should be placed in a OnPaint() or OnDraw() handler, regardless of GDI or GDI+ rendering.
Best,

thank for your replies guys.

hmm It was something else probably.
You can make GDI+ calls anywhere (of course, all the usual thread safety issues apply if you're
using multiple threads).
If you're using GDI+ extensively, you can do the GdiplusStartup() just once - main/winmain is
fine - and call GdiplusShutdown() just once after all drawing is done - just before returning
from main/winmain is fine.
If you have trouble in other functions you can always post related sample code here

we can select only file name not whole path
Please any one told me how i can solve this problem

Your table will need to contain a blob-type field. You would then copy the file's bytes to this field just like you would any other field. The fact that the bytes come from a file is irrelevant.

Hi,
I have a console app that is called by another program. I would like my console app to run hidden, is there a way to achieve this ?
Thanks

Thanks tox, but I cannot modify the call to the console app (otherwise I would have done what you said, trivial, of course). I must hide the console app from within the app directly.

a console program cannot hide itself unfortunately (not that easily AFAIK at least)

If you have control of the Console App end you could make it a fake Console App i.e. make it a Windows App but don't create any Windows just use AllocConsole if and when you do want a Console to appear.
The difference between the two is just a setting in the PE Header stuff on the front of your executable which is picked up by the C Runtime to determine it's mode setting. If it determines it's bootstrapping a Console App it allocates a Console otherwise it doesn't. There are other differences, in IO for example, but they all boil down to different paths in the startup code of the CRT. There's nothing, for example, to stop a Console App creating Windows and doing GUI stuff. In fact many DirectX games are done this way. They start out running as Console Apps and bootstrap DirectX from there to take over the entire screen.;) Equally A Windows app may have no actual Windows and could even have a Console if it decides to create one. I do this lot for scratch/testing type apps.
Nothing is exactly what it seems but everything with seems can be unpicked.

This sounds interesting. How would you call a console from a win32 app ?

First off you need to get yourself a Console and then you can use stdin and stdout as normal. Have a look here http://msdn2.microsoft.com/en-us/library/ms682528.aspx[^]
or you can use API calls like BOOL WINAPI ReadConsole( HANDLE hConsoleInput, LPVOID lpBuffer, DWORD nNumberOfCharsToRead, LPDWORD lpNumberOfCharsRead, LPVOID pInputControl );
I have a pretty much complete wrapper class for the Console API functions which I may post on CP at some point if anyone's interested.;)
