It is crashing because the virtual function pointers are not the same on the client and the server. Your current approach is really bad, try looking through the source of some open source client/server network games for some better ideas.

Greek Language in MFC App

I am developing a piece of software for my Diploma Thesis Project. When I created the framework with AppWizard, I was asked what language I wanted my resources in. The only choice was English (U.S.). But I run a Greek version of Windows 98 and, after all, Greek is my mother tongue. How can I have an application with all resources in Greek?

MSDE/SQL status

I would like to check the status of the SQL Server Service from within a C++ app.
My Installshield app installs MSDE if needed so I can assume SQL Server is a least present on the PC.

The functions I am looking for:

- See if it is installed - I currently do this via CurrentVersion item under the Software\Microsoft\MSSQLServer\MSSQLServer\CurrentVersion key

- See if it is running

- See if it is configured to start automattically at boot time

I would also like the ability to set up SQL Server to run and start at boot time from my app as well.

The difficult part is that I am looking to do this under Windows 98, ME, NT, 2000 and XP. I know there are functions in NT, 2000 and XP that I can use but I need all OS's.

Thanks
AW

You need to Cheek the status Service.
Use OpenService and then use QueryServiceStatus for check the status of service....

It appears OpenService and QueryServiceStatus do not run under Win 98.

What is a good C++ replacement of CString::Replace. I have a component with approx. 160 CString::Replace s. I am looking for a replacement for speed and portibility to ATL.

here's how i do it with std::wstring:

void replace_all(wstring& target, const wstring& to_find, const wstring& replacement )
{
   if (to_find.empty())
      return; 
   
   size_t replace_inc = replacement.length();
   for (size_t loc = target.find( to_find ); 
      loc != wstring::npos; 
      loc = target.find( to_find, loc + replace_inc ) )
   {
      target.replace( loc, to_find.length(), replacement );
   }
}

If you don't mind a little unsupported code you can use CString from WTL.

I want to catch WM_CLOSE from WinAmp and then my app will do something.
Is it possible to catch a windows message in my app that is in WinAmp??

You need a Hook to do that. See SetWindowsHookEx

The Winamp sample from their site subclasses the Winamp main window. Just follow that and you'll see all messages first, so you can act on WM_CLOSE (or anything else you want) before Winamp sees it.

Strange dial-up behavior in Win2000

Joaquín M López Muñoz30-Nov-01 4:20

Joaquín M López Muñoz

30-Nov-01 4:20

I'm not 100% sure this is the right place to post this problem, as it is not programmatic strictly speaking, but anyway...

I've got a program that installs some modem .inf drivers, then creates a dial-up entry and uses it via RasDial. Everything's pretty straightforward and the program runs fine in Win9x. In Windows 2000, however, weird things happen. The program seemed to erratically work or fail to work depending on the drivers I'd previously installed. Finally I isolated the cause of the problem, and it seems to be that, no matter which driver I instruct the dial-up entry to use (with RasSetEntryProperties), it is the last installed driver which is used. I can check this by enabling logs for the drivers and verifiyng it is actually the last installed modem the one that gets accessed instead of the modem the dial-up entry is set for.
What's even more strange, I'm able to reproduce this exact behavior without using my program, i.e. by creating manually the dial-up entries and double-clicking them. This really strikes me, since it seems too gross a bug to have went unnoticed for so long. Checked MSDN, the web and the Usenet and I've found nothing related to this problem, except the article Q162219, which anyway is about NT4.0 and not 2000.
This is driving me nuts, any idea, suggestion, whatever, will get my eternal gratitude Smile | :)

.
Machine is Win2000 spanish version, SP2. Plenty of resources, freshly installed.
If anyone wants, I would gladly send him/her the offending .inf drivers, though I don't think these particular drivers make any difference (who knows, anyway).

Thanks for your help, regards,

If you can ensure excel will be installed on the machine(s) where your program will run, you can use Excel's COM interface to create a new worksheet: (example for Excel 97)

import interfaces (adjust to install path for office)

#import "C:\Program Files\Microsoft Office\Office\MSO97.DLL"
#import "C:\Program Files\Common Files\Microsoft Shared\VBA\VBEEXT1.OLB"
#import "C:\Program Files\Microsoft Office\Office\EXCEL8.OLB" \
        rename("DialogBox","_DialogBox") \
        rename("RGB","_RGB") \
        exclude("IFont","IPicture")

using namespace Excel;

launch Excel, create new workbook

_ApplicationPtr pApp(__uuidof(Application));
pApp->Workbooks->Add();

display to user

pApp->PutVisible(TRUE);

For more information on manipulating Excel via COM, see the MSDN documentation. For more on using the Excel COM interface from Visual C++, see Igor Tkachev's article Using MS Office in an MFC Application.

Like a few others already have said, it's actually the server service.

The server service handle NETBIOS, which makes other computers able to access your shares, and makes you able to access shares, and a lot of other stuff...

How it is possible to delete a CWinApp object (theApp) programmatecally???

30-Nov-01 0:54

Hello,

How it is possible to delete a CWinApp object (theApp) programmatecally???

I explain my problem:

My main programm is a console programm (then it use no frame).
When a user type a command in the console, the main programm create a CWinApp
object and build a CMainFrame object using a DLL.
To close the main frame (ie the CMainFrame object), the user use a menu option
and I send a WM_CLOSE message to CMainFrame.
CMainFrame is correctly destroyed, but the CWinApp object is not deleted...

How it is possible to delete a CWinApp object (theApp) programmatecally???
