I want to load all images from a folder. I can used CFineFile to search all the files in the folder. But the CImage.Load function does not read the directory function, so I have to change the current working directory before loading the image.

either use full path name by merging the directory name with the filename, or you can use BOOL SetCurrentDirectory( LPCTSTR lpPathName); to change the current working folder
the first method is preferable.

Do you need to GetCurrentDirectory and SetCurrentDirectory or you need to FindFirstFile for read files
|

I did check all the functions yesterday but I just couldn't find the SetCurrentDirectory. Anyway, it works today. Thank you all guys.

SetCurrentDirectory might be confusing to the user. Consider using PathCombine to get an absolute, rather than relative, path.

How are you going along with the declaration of variables?

in funtion AfxCallWndProc

What error (e.g., compiler, linker, exception, assertion)? What does the DDX statement look like? Is the variable present in the class' definition?

I want to handle Desktop menu context, the menu is shown when you rightclick on every blank point on the Desktop. Could you tell me how to do that please?
Thank you in advance!
|

Yes, thank you very much! I admire you and your work!
By the way, I want to ask for one thing more. I have a dialog. When I right click on that, I want to show Desktop menu context as well as add my own menu item. Could you be kind enough to help me please? Thank you very much!
Have a nice day!

Hi there,
I would like to know if I can call the destuctor explicitly in case of
containership.
Lets consider an example:
class A
{
public:
~A()
{
cout <<"~A()"<
|
|
|
|
|
There's no need of calling the destructor of A explicitly. Since the object of class A is being created in B, after the destructor of B get's called the destructor of class A is also called.
#include <iostream>
using namespace std;
class A
{
public:
~A()
{
cout <<"~A()"<<endl;
}
};
class b
{
a="" a;
public:
~b()
{
="" cout="" <<="" "~b()"="" endl;
="" a.~a();="" try="" uncommenting="" this="" line
="" please="" pay="" extra="" concentration="" here..
}
b()
{
="" cout<<"b's="" constructor\n";
}
};
void="" main()
{
="" b="" b1;
="" *b="new" b();
="" do="" something="" here
="" delete="" b;
}=""
=""

Thanks in advance,

No, It will be called before B's d'tor.
