True, there are several alternatives. But I may intend to use the result at a later point in time and was wondering if there was a standard way of marking the return value as unused.

Does UNUSED() (defined in Afx.h) do the trick?

Gak! It seems to be defined for release builds only. How vexing.

I'm using a HTML dialog and I want to be able to hit one button, HTML or regular, and have it call C++ code and open a web site in the dialog box. I can currently make a HTML button either call the website or run the C++ code.
I think that I would rather have a regular dialog button, so it doesn't dissappear when the website is pulled up. Any help with the call to open a web site with VC++.net code would be great. I'm running Visual Studio.net Pro.

Currently I'm developing an application with "command window", which consists of two edit boxes: for user input and program output.
As I've been using WIndows 98...Me...2000 everything was all right. But recently I've moved to Win XP, and found out that it's impossible to rpint anything in output window.
I'm using SetWindowText() for output.
Any ideas?

Window handle of output window is valid on the moment u try to settext here?
|
|
|
|
|
Yes, it's valid.
Moreover, there're some kind of output: a line of several blanks appears instead of my text.
|
|
|
|
|

maybe regional settings?

Do you mean if they connected through Windows Terminal Services? If so, have a look at WTSEnumerateProcesses().

hi
in the following code:
PRINTDLG pd;
AfxGetApp()->GetPrinterDeviceDefaults(&pd);
DEVMODE FAR *pDevMode=(DEVMODE FAR *)::GlobalLock(pd.hDevMode);
...
DM_PRINTQUALITY of lpDevMode->dmFields is set but dmFields&DM_YRESOLUTION is not set. why?
(lpDevMode->dmPrintQuality,lpDevMode->dmYResolution) is (-3,0)!!! why?
i can print without any problem in applications like MS_Paint. how do such applications calculate the printer resolution? they may also bring up the print preview environment with no problem.
what's the reliable way for calculating printer resolution which works with all printers?
HP LaserJet 4 examined and it's ok with this method (600x600)
HP Deskjet 3650 examine and it's not ok (-3,0)
what's the problem and how can i resolve it?
what's wrong with the method?
thanx

"Active window" is too vague a term to provide a specific answer for. Is it a dialog, a control on a dialog, a view, a control on a (form) view, or something else? Please explain further.

if i understood u well:
try following:
HWND hwnd = FindWindow(...); // or sequnce of call of FindWindowEx
// to know a valid window's tree use spyxx from the vs tools.
SetWindowText(hwnd, "SomeText"); // This code change captions.
// or to fill up an edit
SendInput(...)

Are you talking about the desktop's background (i.e. wallpaper)? If so, check out SystemParametersInfo(SPI_SETDESKWALLPAPER, ...).

Yes.
You need to familarize yourself with all of the standard controls that are available (e.g., MFC, ActiveX) so that you will know what each can and cannot do.

Hi,
Recently I was testing an activeX component into an MFC application developed with Visual Studio .NET 2002 (MFC 7.0). Because I have some problem with it, I test other known Active X (as Microsoft Forms 2.0 Command Button and Microsoft Forms 2.0 Option Button) and i get problems too. I can move controls, some dialogs are blocked...
Have you ever used any ActiveX component in a Visual Studio .NET 2002 MFC Application? Have you ever get any problem with it?
Thanks for your attention.

I just created a test dialog with my VS .NET 2003. In it I placed Microsoft Forms 2.0 Command and Option Buttons. When I used the Test Dialog option to test-run the dialog, both ActiveX controls were displayed properly.
You should try using the ActiveX Control inside the ActiveX Control Test Container. If they run properly, then the problem is in Visual Studio .NET 2002. Perhaps a bug ?

Yes, all controls I have tested are showed properly. But i have problem when trying to move, for example. Add a commandbutton and try to use SetWindowsPos to move the button. Other error i have is that when I use option button activeX, the application launch an exception.

I must be being really stupid here; but I can't see any way to remove the sunken border which appears by default around a dropdown combo box. Is there any way to remove it?
