I have a MDI apllication with modeless property sheet. I want to create and display edit boxes on one of the property pages. They must be created on WM_LBUTTONUP event in my View-derived class..
So please, tell me, what's wrong in here:
class CInput : public CPropertyPage<br />
{...<br />
void AddEditBox();<br />
...<br />
}<br />
<br />
<br />
void CInput::AddEditBox()<br />
{<br />
<br />
CRect rect( x1, y1, x2, y2);
int ID = 4000;<br />
<br />
CEdit *p = new CEdit;<br />
<br />
p->Create( WS_CHILD | WS_VISIBLE | WS_TABSTOP |<br />
ES_AUTOHSCROLL | WS_BORDER | WS_DISABLED, rect, this, ID );<br />
<br />
}
Now, I want to call this function from my View class (on WM_LBUTTONUP event)
void CMyView::OnLButtonUp(UINT nFlags, CPoint point) <br />
{<br />
...<br />
CInput inp;<br />
...<br />
inp.AddInputEdit();<br />
...<br />
}
but Create function (in the AddInputEdit) returns 0..? why? what I did wrong..?

I am going to guess that the CPropertyPage you are trying to create the edit control on does not exist. try this:
void CInput::AddEditBox()
{
ASSERT(IsWindow(m_hWnd));
...What happens now???

But how can it be..? I create my property sheet (with both property pages..!) in CMainFrame::OnCreate(..).
Anyway, it tels me "debug assertion faild" when I'm trying to click..and what should I do..?

What you are doing in your OnLButtonUp method is creating a new instance of your CInput class. What you have to do is get access to the one you created in CMainFrame::OnCreate and do the operations on that one.

Thank You very much for your help..
but I'm very sorry for another stupid question: how can I do that? To tell the truth, I don't have a single idea of that..
I've created my property sheet using the Visual C++ components, so it's quite standard..
what would you suggest..?
thank You in advance..

Hi,
Until last week, I was programming with Visual C++ 6.0.
Now my company has installed Visual Studio .NET.
I want to compile an old project.
In Visual C++ 6.0 I was able to set the directories of include and source files from the Options dialog.
Where can I do that in Visual Studio .NET ?
Thanks,
Claude

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!

delete it from menu "image" in resource edit
includeh10
|
|
|
|
|
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?
includeh10
|
|
|
|

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".
includeh10

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.

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.
includeh10

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

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;
}
};
