Binary representations of floating point numbers are pretty interesting. If you read the link below, you can see that IEEE floating point numbers can't represent 1/10 exactly, which you would think is strange, but since it's represented in binary, isn't so strange. Anyways, I don't have the answer to your question, but I bet somewhere in the MSDN does (maybe even the link below?).

Setting Bitmap Background for CProgressCtrl

Does anyone know the technique to allow a background bitmap to be displayed for a CProgessCtrl.

Specifically what functions to override and implement. I think it is not possible to use DrawItem unless you make CProgressCtrl to be Owner Drawn.

Many Thanks In Advance

Hi,
I dont know can implement this technique or not? But this is an idea:
1- Create a PictureBox control to show your bitmap
2- Use SetParent API function to change parent of PictureBox control.
3- Set your ProgressBar control as parent of bitmap PictureBox.

special .lnk files

I am attempting to programmatically create a copy of a shortcut using the IShelllink interface. When I interogate most *.lnk files, the GetPath function returns a true target ie. "C:\Program Files\Adobe\Acrobat 5.0\Reader\AcroRd32.exe". There are some special shortcuts however, that behave differently. For example, a shortcut to MS Word returns the
C:\windows\installer\{ some guid }\wordicon.exe. from the GetPath function.

How can I determine the true target (ie: winword.exe ) given the information from the IShelllink functions?

Any suggestions?

We actually do just what is described above. We are interogating the Microsoft Word.lnk file ( the shortcut installed in the Documents and Settings\AllUsers.Windows\StartMenu\Programs\Office\Microsoft Word.lnk). The problem is, the IShellLink->GetPath function returns C:\windows\installer\{ GUID }\wordicon.exe . But we all know that when a user runs Microsoft Word, the process running is called winword.exe. How does the system launch winword.exe when the shortcut target is wordicon.exe ? Smile | :)

LAN connection test

What is the best and/or the most reliable method of testing of a LAN is connected to the Internet.

The Wininet APIs make it easy to tell if the user is connected to a dialup modem, and a LAN, but there is no direct way to tell if the LAN is connected to the Internet.

Sending an IMCP packet is not a possibility, other than that I am open to your suggestions.

Thanks

Adding color to a row in a list control

29-Jan-03 12:56

I want to give color red for status = "Late", and blue for status = "Assigned" for each row in a list control. I tried ON_NOTIFY as suggested by many programmers found from www.google.com. But I can't get it to work. Here is the ON_NOTIFY function:

BOOL CProjectSearchView::OnNotify(WPARAM wParam, LPARAM lParam, LRESULT* pResult)
{
NMHDR *p = (NMHDR*) lParam;
//take the default processing unless we set this to something else
if (p->code == NM_CUSTOMDRAW)
{
if (m_pSet->m_STATUS == "LATE")
{
*pResult = CDRF_DODEFAULT;
NMLVCUSTOMDRAW* lvcd = (NMLVCUSTOMDRAW*)p;
if (CDDS_PREPAINT == lvcd->nmcd.dwDrawStage)
{
*pResult = CDRF_NOTIFYITEMDRAW;
}
else if (CDDS_ITEMPREPAINT == lvcd->nmcd.dwDrawStage)
{
//this is the prepaint stage for an item
COLORREF crText;
crText = RGB(255, 0, 0);
//store the color back in the NMLVCUSTOMDRAW struct
lvcd->clrText = crText;
//tell windows to paint the control itself
*pResult = CDRF_DODEFAULT;
}
}
}

return CRecordView::OnNotify(wParam, lParam, pResult);
}

Don't call the base class OnNotify(), it's wiping out the return value you store in pResult.

Windows XP Home or Professional?

NetServerGetInfo allows you to get the version information for a computer on a network, however, it doesn't seem to have a method for returning the suite information.

For example, both XP Home and Professional return the 5.1 as their version number, but unlike the GetVersionEx, NetServerGetInfo doesn't return a suite mask.

So, how do you differentiate between the two when getting their information over the network?

Jon, I don't think it's possible.
I don't have either about to test on, but I think you have found a genuine glitch.
I think that "Windows Server 2003" will probably identify itself differently. (I hope)
The only other way I guess is to test if something fails to run on the Home "Suite".
