what is the bellow macro mean? (in icrsint.h)
"#define classoffset(base, derived) ((DWORD)(static_cast<base*>((derived*)8))-8)
"
I think it offset to the vtable of the base class. is it right?

Hi,
I have some codes developed using VC++6.0 on Windows 2000 Professional RC3:
...
SetCommBreak(commPort);//comPort is a handle to com1
sleep(certain_value);//
ClearCommBreak(commPort);
...
I have a sniffer program running on another pc B which has special cables connected to the pc A running above program, and A is connected to pc C.
B detects one and only one byte which is 0x00 when above codes are executed when certain_value is larger than 10, and sometimes none or 0xff when certain_value is less than 3. I am pretty confident the sniffer program is OK.
My question is: is data 0x00 supposed to appear on the line?
What I want is to send a break signal from A to C AND C won't think A sends some thing before the break signal.
By the way, I have tried PurgeComm(..) before setcommbreak, it doesn't work.
Is it a W2K thing or this is the way it works?
Thanks a lot
Barry

Hi,
I had the same situation a LONG time ago... When I was setting\clearing the break signal one character (0xFF) was transmitted. In my case it was not a problem, because as soon as I detect a Break signal I clear all my buffers. Probably you should change the way you exchange the data, so that an extra character will not destroy the information. Think about something old and simple as Kermit/XModem/YModem protocols.

Does anybody know how to change the selection color of a CRichEditView?
Thank you in advance...
|
|
|
|
|
CHARFORMAT cf;
CRichEditCtrl& r = GetRichEditCtrl().GetSelectionCharFormat(cf);
long iStart, iEnd;
r.GetSel(iStart, iEnd);
r.GetSelectionCharFormat(cf);
cf.dwEffects ^= CFE_AUTOCOLOR;
cf.crTextColor = RGB(163, 15, 200); //Choisi ta couleur
cf.dwMask |= CFM_COLOR;
r.SetSelectionCharFormat(cf);

I need to save a key and all it's subkeys.
The key is: HKEY_CURRENT_USER/Software/{company name}/{app name}
I then need to restore all those keys to a new {app name}
How do I do that ?
I know the functions: RegSaveKey and RegRestoreKey, but I need to do that under win95/98 also and RegRestoreKey is not available under these OS.
thanks,
Louis.

Try with RegSaveKey - RegReplaceKey pair
|

Yes I'm ready to 'try' but the doc says that the change will be effective only after reboot!! Not very elegant
to ask your users to reboot their machine after starting up
the program.
Have you tried this function ? Is that really the case ?
thanks,
Louis.

Enumerate all the keys and values in the tree.
Then write out a file in the REG format that RegEdit or RegEdt32 uses.
You can then run the RegEdit passing it command line arguments to reload the REG file.
The REG files are text files.
No reboot would be required.

I'm using a CPropertyPage derived class in wizard mode. To change the caption of the wizard dialog after a DoModal() call I use the following code in one of the propertypages:
CEvaluatorWzd *pEvaluatorWzd = (CEvaluatorWzd*)GetParent();
int nPage = pEvaluatorWzd->GetActiveIndex();
CTabCtrl* pTab = pEvaluatorWzd->GetTabControl();
TC_ITEM ti;
ti.mask = TCIF_TEXT;
ti.pszText = pszText;
ti.cchTextMax = 100;
pTab->SetItem(nPage, &ti);
CEvaluatorWzd is the derived from CPropertySheet
This works fine for the first most pages, except for those pages where I return -1 from a CPropertyPage::OnWizardNext or ::OnWizardNext to prevent the wizard from changing pages
HELP!!!

What do I need to write add-ins to explorer? Is there a special sdk to use or what?
Any Urls with tutorials / descriptions on this subject would be apreciated.
|
|
|
|
|
What type of add-ins are you referring to? DeskBands, Explorer Bars, ToolBars, Browser Helper Objects? Other?
The "Creating DeskBands with an ATL Object Wizard" in the ATL section, has links to MSDN Online resources for creating deskbands and toolbars, there are old MSJ/MIND articles that explain how to do browser helper objects and explorer bars. The links I made reference to are in the comments section of the article, in one of the postings from me.
Hope this helps,
-Erik

CWinApp::m_lpCmdLine
Corresponds to the lpCmdLine parameter passed by Windows to WinMain. Points to a null-terminated string that specifies the command line for the application. Use m_lpCmdLine to access any command-line arguments the user entered when the application was started. m_lpCmdLine is a public variable of type LPSTR.
You could use any number of the 'command line option parsers' available eitehr here or at codeguru.com to break up the command line string.

Yes , it's posible . Search at msdn.microsoft for "Browser helper objects" .The parsing , that's another story ...

This Microsoft article http://support.microsoft.com/support/kb/articles/Q99/8/00.ASP
says that by just calling ShowWindow(SW_HIDE) will hide the app from
both the task bar and task list. I tried in Win98 and it just hides from task bar but
NOT the task list. Any help is appreciated.
Thanks.
|
|
|
|
|
If 'Task List' means 'Process List', use RegisterServicesProcess
function. Register service program through this function,
this process will be not shown at CTRL+ALT+DEL dialog box.
