Since DirectX has been bundled with Windows ever since Win98, that's not really a problem any more

I am not sure that this will work with windows NT (if that is a concern of yours) because WinNT has directX 3...

In any case there is no reason why you cannot use MFC and DirectShow or VWF.

I have already downloaded and installed DirectX 9 SDK on my machine. Thanks a lots.
BTW, if the coding for video capturing should be done on Linux instead of Windows Platforms, anybody has any idea?

No design forum hey Chris?
Here's a puzzle for you guys & gals. Someone who's working on a domain model-based system will have a nice solution for me I hope...
The idea of building a domain model is so that the valuable parts of a system (i.e. business logic) are portable and isolated. However, I'm having trouble working out a nice way to move constraints that apply to multiple objects (multiple rows in the same table) away from the database and into the domain model.
For example, the constraint that two customers cannot be given the same names.
The obvious choice is a constraint on the table, however this moves logic out of the domain model.
Mediator classes etc are of no use, because checks cannot be made at the time of commit.
The problem might be associated with the implementation of Unit of Work that I'm using (much like Martin Fowler's) - checks need to be performed at some point in the commit process (any earlier and there is an opportunity for error) but before the end of the committing database transaction (otherwise no rollback is possible).
Hope this makes sense  thanks if you can help.

Does anyone have any tricks for auto-restarting an app? I have a few settings in my app that require the user to close the app and then restart it for the settings to take affect. It would be nice to auto-restart for the user if needed. I know I could do it with a seperate exec but I was hoping to stay away from that.
Any ideas?

You could try executing your own program using ShellExecute() as the very last thing before you exit. Use GetModuleFileName(AfxGetInstanceHandle()) (if you're using MFC) to get your exe filename and path, or GetCommandLine() if you want to reuse all the same parameters as well. You can strip the parameters off if you don't need them.
Hope this helps

Use the proper tag. Check the stylesheet.

Thanks Ryan,
That did the trick. I actually spent time digging around the css for the <proper> tag. Now, don’t I feel stupid. I guess this proves I'm not a "web page programmer" - whatever they are.

Hi,
I am using VC++ and able to open an Excel file: File.xls (if it does not need a Password) with the following code:
<br />
CDatabase database;<br />
CString Xfile = "c:\\File.xls";<br />
<br />
sDriver = GetExcelDriver();<br />
if( sDriver.IsEmpty() )<br />
{<br />
AfxMessageBox("No Excel ODBC driver found");<br />
return;<br />
}<br />
<br />
sDsn.Format("ODBC;DRIVER=<br />
{%};DSN='';DBQ=%;PWD=ATC",sDriver,Xfile);<br />
database.Open(NULL,false,false,sDsn);<br />
However, with the same file, if I use Save As (with
Option) with Password:ATC, then when I run the same
program, it said: Could not decrypt file
Anyone knows what was wrong?
Many thanks

Hiya I have a string like:
char buffer[] = this,is,not,needed,12,grahamoj,34,this,is,not,needed,either;
What I need to do is search for 12 and then do a search after that for the 34, and extract the part in between them e.g "grahamoj" for displaying..
I have been using strstr to search the string but can't get it right.
Can anyone help me on this..
Thanks.

char *p1 = strstr(buffer,"12,");
if(p1)
{
p1 += 3;
char *p2 = strstr(p1,",34");
if(p2)
{
*p2 = 0;
printf("%s",p1);
}

I don't get when the current selection is actually the new selection made by the user. When I'm calling GetCurSel()with my combo box, I'm getting the previous value that was in the combo box. I've tried it in OnOk, OnCurSel,OnSelchange and OnSelendok. Each time the currently selected item is seen as the previous item, not the new item that was selected? What's up with that?
Here's the code I'm trying to execute! 
void RDialogForControlSegments::OnSelendokSegmentGainMatrixCombo() <br />
{<br />
this->m_dwGainMatrixId = <br />
this->m_ctrlSegmentGainMatrixCombo.<br />
GetItemData(this->m_ctrlSegmentGainMatrixCombo.GetCurSel());<br />
<br />
}

Intellisense shows that I can access myPlines (myGroups[i]->)... why can't I access myVerts? (see bold code below). Shouldn't this work like a nested structure? Thanks for any help.
class Group
{
public:
list < Pline * > myPlines;
void addPline(Pline *p) {myPlines.push_back(p);}
}
class Pline
{
public:
void addVert(CPoint *v) {myVerts.push_back(v);}
void removeLastVert() {myVerts.erase(myVerts.end());}
list < CPoint * > myVerts;
};
**********FormView.h****************
Group *myGroups[10];
*********FormView.cpp ***************
FormView::OnDraw(CDC* pDC)
{
pDC->Polyline(myGroups[i]->myPlines[k]->?
}
**********************************************************
**********************************************************
I had hoped it'd work like this:
*************** Nest.h *******************************
typedef struct {
int *x1;
} One;
typedef struct {
One *x2;
} Two;
typedef struct {
Two *x3;
} Three;
class Nest
{
public:
Nest();
Three myNest;
virtual ~Nest();
};
************** Nest.cpp *********************************
Nest::Nest()
{
myNest->x3->x2->x1 = 10;
}

The STL list, which you have used for myPlines, does not overload the array access operator, []. If you need to access it using this operator, you should use a vector instead, otherwise you should be iterating through the list, rather than trying to retrieve an item at a specific index.

Hi,
I have a function
bool equal(double val)
{
if(val == 0.0) return true;
else return false;
}
if val = 0.0;
function will return true
if val = 0.0000000000000001;
function will return false
Is there a way to set a tolerance so that 0.0 == 0.000000000000001 -> true?
Thanks
Everything's beautiful if you look at it long enough...
