Hi,

I have an activex developed with MFC that now needs to load a managed
assembly and
I want to publish the activex in a cab with all the dlls.

The only way I set it to work was adding a /manifestdependency in the
activex for the assembly and copying it to the IE directory.
Nevertheless, the assembly must also be in the activex directory for
registration. My purpose is to only have this copy of the assembly in
the activex directory.

I tried to change the lpAssemblyDirectory using Activation Context with
no luck.
I also tried to load the assembly with the full path, which gave no
error, but when the managed objects are created it is performed another
load of the assembly in the IE directory (I saw the binding logs).

I also tried to sign the assembly but the activex registration fails
after including the publicKeyToken in manifestdependency.

Any suggestion? Confused | :confused:

Thanks a lot...
Sandra

Hi All,

I derived a class from CButton and I'm creating pointers with style BS_OWNERDRAW. This works fine if i give style as WS_CHILD|WS_VISIBLE|BS_OWNERDRAW.

But now i want to custom draw my Radio Button, i giving style as WS_CHILD|WS_VISIBLE|BS_OWNERDRAW|BS_AUTORADIOBUTTON.

But my DrawItem method is not getting called...if remove the BS_AUTORADIOBUTTON style my DrawItem method is called..

Why is this happing?... How can i custom draw my button as radio button..

Thanx

BS_OWNERDRAW
Creates an owner-drawn button. The owner window receives a WM_DRAWITEM message when a visual aspect of the button has changed. Do not combine the BS_OWNERDRAW style with any other button styles.

Hi Arends,

Thanx.. actually i refered Jan'2005 MSDN.. it says..

Creates an owner-drawn button. The framework calls the DrawItem member function when a visual aspect of the button has changed. This style must be set when using the CBitmapButton class.

Now i'm facing another problem, even though i set the checked state by SetCheck(BST_CHECKED), i'm not getting the BST_CHECKED value while i'm using GetCheck()..

Any Idea...

Thanx again..

If you run this code do you get any change or its like your problem

<br />
CButton m_Button;<br />
myButton.Create("Test", WS_CHILD|WS_VISIBLE|BS_AUTO3STATE,<br />
  CRect(0,0,100,23), this, 1);<br />
m_Button.SetCheck(BST_CHECKED);<br />

Hi Whitesky,

The above code will work fine..

My problem is i have to draw a custom option(Radio) button.
So i derived a class from CButton and i override the DrawItem method...

As per MSDN we cannot combine any other style with BS_OWNERDRAW.
Always i'm getting BST_UNCHECKED, so i cannot able to draw the checked radio.

in DrawItem, DRAWITEMSTRUCT::itemState has no ODS_CHECKED flag and also if i use the GetCheck() API it returns BST_UNCHECKED.

Maybe its not good way but its possible if you use of DrawItem you can imitation behavior of checkbox for radio button (once I tried many years ago with three buttons(checkbox)and it worked)

I’m adding a MFC window to an existing application. When I compile the “Create” everything is fine, but when I compile I get an acception:
ENSURE(afxOccMgr !=NULL);

Here is my code examples

//In MainFrm.cpp
CMainFrame::CMainFrame()
{…
AfxEnableControlContainer();
…
	pMainFrm = this;
…
	AfxOleInit();
….
}

//in my subclass.h
Class Mysub : public CWnd
C3DWindow	*m_p3dWnd;

//in my subclass.cpp
Extern CMainFrame	*MainFrm;
…


MySub::Load()
{…
	m_ p3dWnd = new C3DWindow();
…
	bRet = m_ p3dWnd ->Create("Internal_Win", 0, Rect,
                           pMainFrm, ID_MEM, NULL, FALSE);
…
}

Note: I’m developing on VS2005 with Shared MFC and CLR enabled.

Thanks

don't you know HTML ?

when posting code, surround it like this :
<pre>
void main(void) {
::printf("Hello world !!!\n");
}
</pre>

which gives you :

void main(void) {
    ::printf("Hello world !!!\n");
}

hi i want to copy bitmap file from disk to memory and then read it bits and after changing some bits then i want to save agian to the file.
i could do that reading bit by bit but that is slow method which i dont want so i want to copy whole image to memory at once.
i m using this code to read/copy image into memory,

HANDLE handle=CreateFile("D:\\tasleem.bmp",GENERIC_READ,0,NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,0);<br />
	if (handle == INVALID_HANDLE_VALUE)<br />
    {<br />
	  return 0;<br />
    }<br />
	DWORD fileSize=GetFileSize(handle,NULL);<br />
	DWORD bytesReaded,bytesWritten;<br />
	<br />
	unsigned char *Rbuff=new char[fileSize];<br />
	ReadFile(handle,(LPVOID)Rbuff,fileSize,&bytesReaded,NULL);<br />
        if (bytesReaded==0)<br />
		 return 0;<br />
	CloseHandle(handle);

i looked at bytesreaded variable by debugging its equal to the fileSize variable but when i try to display from memory into console it does not show,any it show garbage.
when i write on another file data from Rbuffer then that is copied and iamge is copy of that hence it all works i think problem is with accessing/display values.

i m trying to show bitmapfile header and info header structure of bitmap only for verification that it works or not.here is the code

cout<<"\n Bitmap File header";<br />
	cout<<"\n"<<Rbuff[i];<br />
	i+=2;<br />
	cout<<"\n"<<Rbuff[i];<br />
	i+=4;<br />
	cout<<"\n"<<Rbuff[i];<br />
	i+=2;<br />
	cout<<"\n"<<Rbuff[i];<br />
	i+=2;<br />
	cout<<"\n"<<Rbuff[i];<br />
	i+=4;<br />
	cout<<"\n"<<Rbuff[i];

Just curious, but do you supopose that someone three weeks from now will be able to discern that file represents the size of a file? Confused | :confused:

Why are you allocating chars for an unsigned char variable?

tasleem143 wrote:
cout<<"\n Bitmap File header";
cout<<"\n"<<rbuff[i];< blockquote="">

Use endl instead of \n. Otherwise, cout's caching will mess you up.

Is cout producing anything? If it looks like a memory address, you might need to cast it to a char?

Last time I checked, B, M, p, and ? were all real characters. What exactly are you referring to?
