I have a large icon that I'm using as the 32x32 icon for my application. Visual Studio creates a 16x16 version of the icon to display as the smaller version. I don't like the conversion VS made so I made my own 16x16 version. My question is, how do I incorporate the 16x16 icon into my application? I don't know how to tie it to the application so it gets displayed as the small version of my application icon instead of the VS-generated one.

Thanks for the help!

I don't follow...

What do I delete and how do I delete it? I'm using VS6 if that makes a difference.

I assume you mean to delete the 16x16 version that VS generated? If so, after I do that, how do I tell VS to use my 16x16 version? How do I tie it in?

Thanks,

Ian

do you want to use 16x16 image for icon?

I want my application to use the 32x32 icon when applicable, and the 16x16 icon where applicable. But when Windows needs to show the 16x16 version, I want it to use my 16x16 version, not the one generated by VS.

i think u don't know how to edit the 16x16 image?
when u edit the icon, go to menu image/open-device-image then select 16x16 one from dialog box of "open icon image".

The 16x16 that I want shows up in the resource editor but that is not the one that is being used. Windows is still displaying the one VS generated. I don't know where it's coming from or how to get rid of it and force the 16x16 icon I created to get used.

Each icon resource generally has 1-3 resolutions (16x16, 32x32, and 48x48). To edit a particular resolution, open the icon in the resource editor and select the desired resolution from the Device: combobox.

CWinApp::LoadIcon loads only the 32x32 icon. What you have to do is use the LoadImage() function, specifing the size of the icon you want (16x16) and use that icon in the CWnd::SetIcon() function.

Check out CWinApp::LoadIcon, LoadImage, and CWnd::SetIcon in MSDN for more information.

As it turns out, the problem was that the 16x16 had a lower color depth than the 32x32. I modified the color depth of the 16x16 version to that of the 32x32 version and that fixed the problem. I'm guessing Windows (I'm on XP) defaults to it's own 16x16 version if the one supplied has less color depth than the 32x32 version?

Strange...

Thank you all for your help. I really appreciate it.

class with dynamic array

How would I go about setting up a class with dynamic array?

class CMyArray : public CObject
{
private:
int array[MAXSIZE]; //MAXSIZE is dynamic
public:
CMyArray();
virtual ~CMyArray();
};

I tried using template but when I am getting invalid use of local variable ' ' as non-type argument

int main(){
int size=30;
CMyArray<size> *pMyArray;
pMyArray = new CMyArray<size>;
return 0;
}

try to copy code from MFC class "CArray", then modify it.
do not inherited CObject, it is useless at your stage.

You can use template< class T> class yourClass{
...
Array[T]
...
}
After that you replace class T by interger value

Good luck

I thought template <class t=""> is used for changing int/char/BOOL etc.

Now I am getting invalid template argument for 'size' type expected

template <int size=""> class A
{
char name[size] ;
} ;
when you new a object A you must put extractly number ( real value)
don't put variant . because template is transfer to code at compiler-time
thanks

This array has a static, not dynamic, size. To make it dynamic:

class CMyArray : public CObject
{
private:
    int *array;
 
public:
    CMyArray()
    {
        array = new int[MAXSIZE];
    }
 
    virtual ~CMyArray()
    {
        delete [] array;
    }
};

It is static but it should be dynamically changing everytime the class constructor is called.

Something like
A1 X X X X
A2 X X X
A3 X X X X X X
A4 X X X X

I guess I could do it that way. I thought maybe I could use template.

What's wrong with:

class CMyArray : public CObject
{
private:    
    int *array; 
 
public:    
 
    CMyArray( const int size )    
    {        
        array = new int[size];    
    }     
 
    virtual ~CMyArray()    
    {        
        delete [] array;    
    }
};

Nothing wrong with it. I just wanted to practice using template and see how it works.

Thanks for the help Smile | :)
