I recently ran into a problem related to the topic, was wondering if anyone has any ideas...
The setup:
<br />
class CView<br />
{<br />
friend class CPreviewView;<br />
<br />
protected:<br />
BOOL DoSomething();<br />
};<br />
<br />
class CPreviewView : public CView<br />
{<br />
public:<br />
void SetSomething(CView* pView)<br />
{<br />
...<br />
<br />
pView->DoSomething();<br />
<br />
...<br />
}<br />
};<br />
<br />
class CMyPreviewView : public CPreviewView<br />
{<br />
public:<br />
void SetSomething(CView* pView)<br />
{<br />
<br />
...<br />
<br />
pView->DoSomething();<br />
<br />
...<br />
}<br />
};<br />
CPreviewView is granted access to DoSomething since it's declared as a friend in the CView class. In the CMyPreviewView class, access is denied to DoSomething since CMyPreviewView isn't declared as a friend.
a) If these were my own classes, I could simply add a new friend class statement to CView. Both CView and CPreviewView are MFC classes, and I don't want to touch the MFC code.
b) If the DoSomething function were virtual, I could simply add an override to CMyPreviewView.
* scratch that *
Is there a simple way that I can somehow grant CMyPreviewView public access to CView::DoSomething?

Hi,
This is a very basic question. Don't mind...
I want to append a blank space at the end of a string.
strcat(name, " "); doesnt seem to work. The trailing space is ignored. How can I retain it?
|
|
|
|
|
how is name declared ?
maybe the space is added after the '\0' ?

I don't think so...
say name contains "Mickey"
strcat(name, " "); returns "Mickey" but strcat(name, "Mouse"); returns "MickeyMouse"...
so I don't think the '\0' in name has an influence...
|

I tried appending another word after appending a space... The space was not existant.

If, in the first instance, you can replace C style string handling with the string class, you'll be better off. However, there's no reason I can see for this not to work, all the same.

When the application starts I send the initial directory as an argument...
so the command line is <exename> <rootdir>. now when the folders in the path contains space, it is recognized as more than one argument. The following code should help attach the arguments together... but the space is not being appended...
<br />
if (argc==1)<br />
initpath[0]='\0';<br />
else {<br />
strcpy(initpath, argv[1]);<br />
for (i=2;i<argc;i++) {<br />
strcat(initpath, argv[i]);<br />
strcat(initpath, " ");<br />
}<br />
}<br />

Well, this isn't a fix for the string weirdness, but that code isn't the way to fix the problem with spaces in a filename. Put quotes around the directory name so the OS knows the spaces are part of the name.

Cool... I attempted to pass the path, which was stored in a variable, while using _execl function from another application. It didnt work. now i created a new variable and added duoble quotes before and after the path. It works fine...
Thanks for helping me fix it...

How are you verifying this? Has name been properly initialized prior to calling strcat()?

I got around my problem (see the reply with title " this is what I am trying to do" in the same post). strcat appends blank spaces.
strcpy(name, "Mickey");
strcat(name, " ");
strcat(name, "Mouse");
returns "Mickey Mouse"...
but when I try to do a similar thing (as in my code in "this is what I am trying to do") the blank is not getting appended. I think the arguments are not null terminated. anyway, this is still interesting but atleast my issue was solved...

Your code snippet worked fine for me, although the order of the two strcat() calls should probably be reversed.

Hello,
I am doing a project in c++ which involves basic file operations i.e. create, copy, rename and delete a file. Here the main thing is performance because the number of times these operations takes palce is 10000. so the program loops for 10000 times and also need to clean up after doing everything.
I have to do this, by mounting a file systems and then i have create a directories on that file system and then perform the operations on the file.
Please suggest me some ideas on how to do this.

Have you looked at CreateFile(), CopyFile(), rename(), and DeleteFile()?

Is there an article to introduce how to create shapes in a window on codeproject.com or MSDN? A good, simple-to-use tutorial?
I would like to be able to create the shapes in a window (sort of like a tic-tac-toe diagram.
Thanks,

 Which article? What does GDI stand for? I am a winapp noob.

What is your problem? There are several articels that explains how to draw using GDI, start with the first one: http://www.codeproject.com/gdi/paint_beginner.asp[^]
You've posted your question in the C++/MFC forum, so GDI is the easiest option for simple shapes.
If you are looking how to draw in a WinForms/.NET application you should ask your question in the C++/CLI forum.
