Hi,
I'm no expert on VC++ but the books I've found most usefull are 'Practical C++ 6' By Bates & Tompkins (this has some nice example to get you started and some detail too.
And 'Programming Windows with MFC' by Jeff Prosise, this is my main reference and if I could only have one book on VC++ this would be it. It gives you lots of detail and explains things really well.
(I've just thought - I am using VC++ 6 which is fairly old now, anyway they are the books I use what I use for what its worth.)
If you already know C++ then you've got a good start  Good luck

I guess this has been updated since I bought my copy of Programming Windows95 with MFC.

Hi everyone,
In my code while debugging,
after user breakpoint is called after
this line pops up in debug output line.
I have some doubts that this may be happened
by not cleaning a _bstr_t type variable.
How do i allocate and free this type of variable?
Thank you very much.

well...that's kinda of the advantage of _bstr_t, you shouldn't have to allocate or free memory, because it does that all for you.

Let it go out of scope or set it to NULL.

i am facing some matlab c++ problems. i am looking for some solutions for them. anybody can help me?
thank you very much. 
p/s: thank you Jwood for your information.
Problem 1:
MATLAB SOURCE CODE: [features, targets] = improved_DA1(x, [cluster,0.95]);
MATLAB C++ CONVERSION:
mwArray cluster ;
improved_DA(x, empty(cluster,0.95));
after compiling,……
D:\others\im\me.cpp(116) : error C2660: 'empty' : function does not take 2 parameters
Problem 2:
MATLAB C++ CONVERSION:
I3=uint8(I2);
After compiling,…….
D:\others\im\me.cpp(137) : error C2065: 'uint8' : undeclared identifier
Problem 3:
MATLAB SOURCE CODE:
Smu=zeros(1,Nmu);
for i=1:Ncent,
Smu(i) = sum(std(train_features(:,find(label == i))'));
MATLAB C++ CONVERSION:
Smu = zeros(1,Nmu);
for (i = 1 ; i<=Ncent ; i++)
{
/*232*/ Smu(i) = sum(std(train_features(:,find(label == i))'));
}
after compiling,…..
D:\others\im\me.cpp(232) : error C2001: newline in constant
Problem 4:
MATLAB C++:
……………
double Tmin;
mwArray T;
Nmu = params(1);
epsi = params(2);
/*167*/ T= 3*max(eig(cov(train_features',1)')); //Initial temperature
Tmin = 0.01;
………….
After compiling…….

Hi all,
Wondering if someone could point me in the right direction for a very basic tutorial for using Tab Controls in Visual C++. Been struggling to implement my own for a while now...
Thanks in advance

Hi Friends,
Can any one please tell me how to create Dialog without resource dynamically.
Thanks,
Live and Let live
|
|
|
|
|
take a look at CreateDialogIndirect in MSDN.
|
|
|
|
|
Thankyou for the answer.
Is there any way in which I can create Modal Dialog Box Dynamically without using resource.
Thanks,
Salman

You can override the OnCreate member function, and create controls dynamically there. And handle the command BN_CLICKED of the Ok button and put there your own DDX ....etc. etc.
I think this seems complicated and useless. What do you want dynamic dialog box for? Could you not create the dialog box in resource editor and only make the specific controls visible/invisible at runtime?

Thanks for your reply,
But I have to create OCX of my Dialog so, I want to create DialogBOx without Resource. Any how I got answer and will post this artical on codeproject as soon as possible. But the real problem is even I am able to create DialogBox Dynamically. I am not able to attach the controls to it dynamically. Once I get this answer I will post it as soon as possible.
Thanks,
Salman

I have a web control inside a modeless dialog in view/doc application. The dialog is implemented as a child of the mainframe. The problem is, when something changes in the web control (navigate2() is called), the dialog steals the focus from the mainframe and view.
Is there any way to prevent this, or restore focus back to the previous window who had it?

how do i get the path from where the application was executed ??
i am using MFC.
Thanx.

Use the GetModuleFileName() API.
CString strDirectoryPath;
TCHAR zName[MAX_PATH];
TCHAR* zLast;
::GetModuleFileName(0,zName,sizeof(zName));
zLast=_tcsrchr( zName, (TCHAR)'\\');
if (zLast)
*(zLast+1) = (TCHAR)'\0';
strDirectoryPath = zName;
ASSERT( !strDirectoryPath.IsEmpty() );
return strDirectoryPath;
I Dream of Absolute Zero

|
|
|
|
Thanx i guess this piece of code is little better.
CString strAppPath;
::GetModuleFileName(NULL,strAppPath.GetBuffer(MAX_PATH),MAX_PATH);
strAppPath.ReleaseBuffer();
strAppPath = strAppPath.Left(strAppPath.ReverseFind('\\'));
AfxMessageBox(strAppPath);

you can also check the GetCurrentDirectory() in the Platform SDK out:

Current directory is not what i want, i wanted the location of the exe file.
suppose the exe file is in c:\windows
and if you execute the program from c:\temp then c:\temp is ur current directory and c:\windows is the source directory
