There's also CreateProcess().

Thank you!
I think i have to use this method because I can't find the ShellExecute()function in Embedded C++, which I use.

Hi everybody,
here's a newbie one for y'all:
I was hoping that I'd be able to create an instance of CMap using very simplistic keys with something like:
CMap< int, int&, CMyClass, CMyClass& > m_myMap;
But I get a "'operator =' function is unavailable" error from the compiler. Is this because I have to use keys that are objects of a class, or what?
Best regards,
Håkan Olsson

It is saying that you need to implement an operator = within CMyClass.
CMyClass& operator =(const CMyClass& right)
{
<p></p>
return *this;
}

UHh... OK. I thought that the "= not defined" thing was about CMap member functions not being able to compare keys rather than the objects...?
Anyway, thanks I'll try that!

If it was complaining about a compare method it would be "==" not "=".

what kind of errors ?
( based on Scott Meyers' More Effective C++ )
one problem is that if there are problems when constructing an object, and an exception is thrown, the object will not be destroyed because it is not fully constructed.
one solution, if possible, is to delay the class initialisation after the object is fully created.
Other solution, if the class absolutly needs to create and allocate members in the constructor, is to use auto_ptr pointers instead of ordinary pointers ( see above reference for full explanation )

Hi,
I am a new programmer in C++ and Vb. I have got a dll written in c++ and using that dll in vb. There are three functions in the dll namely
absmov(window,double)
relmov(window,double)
posreq(float *pos)
I have only these infos about the dll. So in vb I declared them as subroutine and passing single for float by ref in posreq which is working just fine but for the others I am passing window handle of the form as window and double value for movement. But it is not working doing nothing. What is the error here. What does this window paparemeter means and how to pass these kind of parameters. Any help will be highly appreciable.

Buddy,
actually window is not a predefined datatype or structure, i think creator of Dll has written his own structure or what ever .
i htink you have to ask developer of dll about what window do.

OK, never posted here before so please feel free to shout at me if i've committed a cardinal sin or something. If you do not then please could you help with my problem.
1. I know no C or C++
2. My colleague is abroad with no internet
3. He is trying to do some error handling using try() and catch(). However, the C compiler says that it doesn't understand the function try(). Does he need to put something in include or something?
Thank you so much in advance if you can help.
Cheers

If its C and not C++ then use Structured Exception Handling. You can search on Google and MSDN for more information about it.
Try, Catch, Throw exception handling mechanism used in C++ and not in C.
I hope this helps
Have a great day ahead!

Thanks for the prompt response!
It is C code within a program that uses C++ (i think!).
Just to clarify then, you CANNOT use try() and catch() within C, only C++?
Thanks again

Yes. The file must be compiled as cpp and probably has to have a cpp extension.

Yes. Try() and catch() are part of C++, but not C itself! Therefore C code cannot use try and catch.
Note that C++ is almost a superset of C. Odds are very good that his program will work just fine if he compiles it as if it is C++ even though it is C. However this isn't 100%. Depends on how it is used.
Note that "extern C" might be required all over depending on how other things are defined. Look this up though, and experiment. (extern C might also turn off exception handeling though, I don't know. See what works, and test carefully, particularly if this is cross platform)

Yes, as I said, try,catch and throw are part of C++ and not C. If you wish to use them in C then one option is to make your .C file to .CPP file and compile with the C++ compiler. All the code remains in C only, just change the extension and use it with C++ compiler. Many a times we use this approach just to use few features of C++ like - strict type checking, ability to declare variables at the exact place where they are needed rather than at start of function etc.
But if you want it to be pure C and compiled in C compiler then better use Structred Exception handling.
I hope this helps 
Have a great day ahead!

Also I hope he's not actually including the parentheses '()'. I don't know, but just in case, it's like this:
try
{
}
catch(CSomeException)
{
}
If I write code in my sleep, does that make me brilliant, or just a lazy programmer?

Hello everyone,
My question is how to change the font color of slide.
I have Automated PowerPoint Using Visual C++ MFC,such as:
_Application app;
Presentations presentations;
_Presentation presentation;
Slides slides;
_Slide slide;
ShapeRange shaperange;
Shapes shapes;
Shape shape;
TextFrame textframe;
TextRange textrange;
Font font;
FillFormat fillformat;
ColorFormat colorformat;
ShadowFormat shadow;
if(!app.CreateDispatch("Powerpoint.Application", &e))
{
CString str;
str.Format("CreateDispatch() failed w/err 0x%08lx", e.m_sc),
AfxMessageBox(str, MB_SETFOREGROUND);
return;
}
app.SetVisible(TRUE); Presentations presSet(app.GetPresentations());
_Presentation pres(presSet.Add(TRUE));
Slides slideSet(pres.GetSlides());
_Slide slide1(slideSet.Add(1, 2));
// Add text to slide, by navigating the slide as follows:
// slide1.shapes(#).TextFrame.TextRange.Text
{
Shapes shapes(slide1.GetShapes());
Shape shape(shapes.Item(COleVariant((long)1)));
TextFrame textFrame(shape.GetTextFrame());
TextRange textRange(textFrame.GetTextRange());
textRange.SetText("My first slide");
}
{
Shapes shapes(slide1.GetShapes());
Shape shape(shapes.Item(COleVariant((long)2)));
TextFrame textFrame(shape.GetTextFrame());
TextRange textRange(textFrame.GetTextRange());
textRange.SetText("Automating PowerPoint is easy\r\n"
"Using Visual C++ is powerful!");
font = textrange.GetFont();
font.SetName("Comic Sans MS"); //Set the font name.
font.SetSize((float)48);
}
Now the question is how to change the font color????
Help me,please!!
Thanks a lot!!;P

hi all,
I want to add multiple rows using Edit Control.
I did like this:
CEdit m_edit;
m_edit.SetWindowText("hellow \n code \n project\n");
But this is not working .
when I compile and run the application.it is displayed like this:
hellow|code|project|
But I want to show the output like this using Edit Control:-
hellow
code
project
So can any body help me to solve this..
Thanks in advance

Did you choose multiline for the options of the edit control ?
Right click on the edit ctrl -> properties -> 'Styles' Tab -> check 'Multiline'.
|
|
|
|
|
hi
yes..I already check the multiline
Is there a another way to set string instead of SetWindowText()
??

Try this instead:
CEdit m_edit;<br />
m_edit.SetWindowText("hellow \r\n code \r\n project\r\n");<br />
