Where would I put the code.. I have already tried this..
BOOL CMyDocumentDoc::OnSaveDocument(LPCTSTR lpszPathName)
{
SetTitle("My Document");
return CRichEditDoc::OnSaveDocument(lpszPathName);
}
And it doesnt work..
|
|
|
|
|
how about
BOOL CMyDocumentDoc::OnSaveDocument(LPCTSTR lpszPathName)
{
BOOL bRet = CRichEditDoc::OnSaveDocument(lpszPathName);
SetTitle("My Document");
return bRet;
}
I am not sure whether it works or not. I am just suspicious that OnSaveDocument will call SetTitle() automatically.

|
|
|
nope  I think when this function returns the title gets changed..
Thanks though

Got it.. Had to over ride the SetTitle and force the name there..
Thanks,
Rob

I have a member variable declared as:
CArray<cpoint, cpoint=""> m_dotArray;
When I am using it, I use CArray::Add to add new dots to it. But I don't want to add duplicate dot, so I derived CMyArray in the following manner:
template <class TYPE, class ARG_TYPE>
class CMyArray : public CArray < TYPE, ARG_TYPE >
{
public:
int AddThis(ARG_TYPE newElement);
};
template < class TYPE, class ARG_TYPE >
int CMyArray < TYPE, ARG_TYPE > ::AddThis(ARG_TYPE newElement)
{
ARG_TYPE existingElement;
for ( int i = 0; i < GetSize(); i ++ )
{
existingElement = GetAt(i);
if ( existiingElement == newElement )
return -1;
}
Add(newElement);
return 0;
}
but when compiling the following error is reported:
error LNK2001: unresolved external symbol "public: int __thiscall CMyArray < class CPoint, class CPoint > ::AddThis(class CPoint)" ......
What did I miss? 
TIA!!

Is this code visible to your project ? Is it part of your project ?
Have you ever tried std::vector ? Unlike CArray, it's powerful, flexible and does not suck.

yes, I have added both the .h and .cpp to my project. Also, I have include the header file when I declare the member variable.
I did a few Build->Clean and Rebuild All, in the hope of getting rid of this problem. But without any success. 
I didn't know anything about std::vector, I would try to read something about it. Before that, what is the correct way of deriving any class from CArray? I think I am not following the correct syntax.

If you search for 'vector graus' in the articles you should find my article on vectors.
I don't know how you would derive from CArray. I'd probably try to contain a CArray instead and see if that worked, assuming I had to.

std::vector - code bloat...
CAtlArray

I'm going to patent thought. I have yet to see any prior art.

CAtlArray, hmm, I should keep it in mind for future use, since I don't need the serialization function here at all.
Thank you.

lol - you just don't give up, do you ? I've never used CAtlArray, is it part of WTL ? How complete is it ? That is, does it offer algorithms etc, or is it merely another container of the sort I could write in an afternoon ?

For 10 points, explain how a "mere container" is a bad thing.

Is the function implementation in the header file (or a #included inline file)? If it is in a .cpp file, then the compiler won't find it when instantiating the template, and so the function will be missing at link-time.

ah Yes. I implemented it in cpp file. After I delete the cpp and move the function definition to the .h file, everything is okay.
Thank you so much!  I am so happy.

Thank god someone answered your QUESTION.

Like you, I have noticed that there are a lot of posters that preach certain methods for doing specfic tasks. While, I think it is OK to provide alternative appoaches to solve a problem...I also think that you should try to answer the question, as posed.

Be fair - I NEVER recommend STL unless I can also answer the question, or the question has been answered. I may not have got it right, but I had a guess.
And the MFC container classes are still a pile of fetid refuse.

Is there an article you can direct me to that will show what you're talking about? If not, I see it as a great opportunity to once again demonstrate your overnight article-writing abilities  .

Yes, that was a major reason I wrote my article on std::vector, to point out all the things that it does that CArray will not. CArray is a perfectly good array class ( they are not hard to write ). But how do you copy the contents of a CArray into a CList or CMap ? STL containers provide a common iterator interface. How do you sort a CArray, or shuffle it, or any other common algorithm ? The stl comes with all sorts of algorithms, and the facility to easily write more.

Can this thing wait not only for socket events but my own as well?
Or how should I interrupt this thing? Or should I wait without and then
check for other stuff to do? What is the best timeout then? 1 Sec? 5 Sec?
Please HELP!

I know how to output an integer in MFC with AfxMessageBox and CString. Here I have no MFC and must use MessageBox. How do I make it show me the number? Lets say its a variable called a, and a=10;

use sprintf to format a char buffer and pass the buffer to MessageBox

Take a look at sprintf() in the msdn...
