It's not a COM project that you are compiling is it?

No. I'm using this zip library[^] and some 3rd-party ActiveX controls[^]. Strangly enough, it seems I have winamp playing and outlook open when it will do it.... I copied the project to my local machine and deleted all the .obj stuff and the .ncb file, rebooted the machine, and the rebuild worked. I feel it's just a matter of time before it does it again...
What's the deal with COM prj? Can it be related? Does ActiveX use COM at all (i wouldn't think so)? Also, why would it be so wishy-washy? You would think if something's wrong, it would hang all the time... I'm keeping track of the clues. Does anything sound fishy to u?

I had a similar problem when the compiler tried to register the COM project. I had some dodgy code in the COM objects start-up code which prevented the COM object being registered by the compiler. Took me an age to fix it.
Although by the sound of it, it's more likely to be something else.

Using VC6, SP? (probably 3, I'm not sure).
If we compile too much modules of our application with debug (/Od /Zi), then we get a floating-point invalid operation in a specific routine of our application. Recompiling that routine without debug (or with debug) does not seem to help.
Only if we recompile everything without debug again (/Ox /Oy-) the application runs correctly again.
If it crashes it always crashes in the same location, and it would even crash on the following source then:
double d1;<br />
double d2;<br />
d1 = 0.0;<br />
d2 = d1 + 1.0;
I've now upgraded to SP5 (hope the problem doesn't occur anymore), but I would like to know if this is a know problem or if anyone of you have encountered this problem too.
Btw, how can you see which Service Pack of Visual C++ is installed? Our system manager couldn't find it out either.
Thanks.

Hi all,
Can anyone point me in the right direction of information about using the Excel grid in a VC++/MFC app? I'm just looking to get the grid on a view / dialog, maybe manipulate some rows / columns (via code), etc.
Is this even doable?

I've been given the task of "evaluating the feasability of using Excel's grid" to work with our app. It's part of a larger grid evaluation thingy I've been tasked with, so I really need to get to grips with using Excel from VC for this one. I did find this[^], which is a nice starting point

Well, good luck. I take it "they" realize Excel needs to be installed on each machine your app will run on... BTW, I once was considering the same thing and after perusing the same MSDN article, I thought: "If all I'm doing is providing excel functionality, why not just use excel (and heaven forbid: VBA  )?" But hey, it's all about the right tool for the job.

Hi,
I have a dialog implemented using the CPropertySheet. To this I add as two pages two diff dialogs. I want the whole thing to be colored diff(grey is boring)
To change the color of dialogs, I can override the WM_CTLCOLOR.
I tried the same with propertysheets, but it fails to change the color.
Any suggestions are most welcome.
Regards,
Deepti.

Hi,
I have a dialog in that i have a picture box,at some point of time i just want to display only the picture box.
I tried with SetForegroundWindow().But it didn't help me.
Regards
Neha

Are you running under W2K or XP? MS changed the behavior of SetForegroundWindow(). What you need to do is attach to the thread that has the foreground and switch from there. Check out
http://www.mooremvp.freeserve.co.uk/Win32/framed_tip033.htm
for a workaround.

I have a dialer that has to enumerate the ISDN modem on a computer. It works fine if i compare the szDeviceType with "isdn" on Win2k. But when I try to test it on win98 it shows the device as "modem" to my dialer even it is isdn. So how can i make sure tht the device is ISDN and not modem even windows is telling me its a modem. I know its not modem but ISDN but windows 98 thinks its modem and so shows 2 modems for both the channels.
how to verify a devide for being isdn or modem.

No one answered you, maybe because you're asking WAY too much,
Have you been doing research, didn't you search for "wave file write", or "wave file format header" ?
Have you searched for samples, technologies, demos... ?
Help us help you by working on your side !

from msdn:
Use the RecordCount property to find out how many records are in a Recordset object. The property returns -1 when ADO cannot determine the number of records or if the provider or cursor type does not support RecordCount. Reading the RecordCount property on a closed Recordset causes an error.
Basically, what you need to do is set the CursorLocation property of your recordset to adUseClient before opening it.

You need to write your own GINA dll. Do a search on msdn for the word "gina.dll" and you'll get enough results to get you started.

I will look into it.
Hopefully this will start me in the right direction.

Can anyone have an idea, how can I trap a SelectChange event in a combo box control that is a member of a class derived from CEdit. Here is my sample codes of the class definition.
class CEditBox : public CEdit
{
// Construction
public:
CEditBox();
// Attributes
public:
// Operations
public:
// Overrides
// ClassWizard generated virtual function overrides
//{{AFX_VIRTUAL(CEditBox)
public:
virtual BOOL Create(DWORD dwStyle, const RECT& rect, CWnd* pParentWnd, UINT nID);
//}}AFX_VIRTUAL
// Implementation
public:
virtual ~CEditBox();
protected:
CComboBox m_cComboUnit;
// Generated message map functions
protected:
//{{AFX_MSG(CEditBox)
afx_msg void OnSelChangeUnitX(NMHDR * pNotifyStruct, LRESULT * result);
//afx_msg void OnSelChangeUnitX();
//}}AFX_MSG
DECLARE_MESSAGE_MAP()
};
