It is the relevance that C code has to C# language...

good! but i think, if i use it, it will increase my dependency on C runtime library. though they are fast but more error prone so beware while using it.

Hi all,
I had my code reviewed and I had a comment that its best to remove the else in this statements:
LRESULT CMainDlg::OnInstall(WORD, WORD wID, HWND, BOOL& )
{
string LaunchInstaller;
string InstallFolder;
InstallClass installclass;
TCHAR tcItemText[MAXBYTES];
if(UpdateList.GetItemText(Select, tcItemText, MAXBYTES))
{
InstallFolder = tcItemText;
LaunchInstaller = installclass.ConstructInstallerKey(IDS_MANAGEKEY, InstallFolder);
if (installclass.InstallUpdate(LaunchInstaller.c_str()))
{
return 0;
}
else
{
LaunchInstaller = installclass.ConstructInstallerKey(IDS_RERITEKEY, InstallFolder);
if (installclass.InstallUpdate(LaunchInstaller.c_str()))
{
return 0;
}
else
{
LaunchInstaller = installclass.ConstructInstallerKey(IDS_RERITEASIANKEY, InstallFolder);
if (installclass.InstallUpdate(LaunchInstaller.c_str()))
{
return 0;
}
else
{
LaunchInstaller = installclass.ConstructInstallerKey(IDS_RERITECHINAKEY, InstallFolder);
if (installclass.InstallUpdate(LaunchInstaller.c_str()))
{
return 0;
}
}
}
}
}
else
{
MessageBox ( _T("Please choose an item to install"), _T("Redmap Update Manager"), MB_ICONWARNING );
}
return 0;
}
Any suggestions on how the code should look like?
Thanks,
Jayjay

Is the value of sDsn correct?
ZhiLiangLin wrote: sSql.Format(_T("SELECT * FROM [%s$A1:IV65535]"),_T("EmailSheet"));
Have you tried:
sSql.Format(_T("SELECT * FROM [%s$A1:B4]"), _T("EmailSheet"));Does it have anything to do with those cells containing numbers? Do any of the rows read correctly?

the api 'getfieldvalue' can't get the value.

So have you used the debugger to step into that method to find out why?

I had to re-install VS2008 when I re-installed the operating system. Somehow the "Just-In-Time Debugger" de not get installed. I tried going to Microsoft downloads for it and all they offer is VS20088 SP1. Every time I installed VS2008 SP1 it messed VS2008 up so I won't install it. Does anyone know how I can get a copy of the "Just-In-Time Debugger" from microsoft?(Microsoft Script Debugger is another name for it).
