I have suggestion for you Nish.When I get into troubles like this,I keep that project away.Do not think about it for some hours,then come back and start from THE BEGINNING.Maybe it works for you too. Smile | :)

Mazy, thinmgs just got even more strange.

I tried out Jason's suggestion and instead of __uuidof(..) I did this :-

HRESULT hr=p.CreateInstance("TestCom.SimplePgp");

And it works fine!!!

Now I gotta figure out why __uuidof() failed both at office and here at home Confused | :confused:

This is my code :-

CoInitialize(NULL);
ISimplePgpPtr p;	
HRESULT hr=p.CreateInstance(__uuidof(ISimplePgp));
if(!SUCCEEDED(hr))
    std::cout << hr << "\r\n";
CoUninitialize();
return 0;

On running this I get this as the HRESULT error :-
-2147221164

VC++ Error Lookup says it is Class not registered
I am sure the class is registered Cry | :((

Make sure its registered by running Regsvr32.exe "yourdll".
Also, try using the version independent progid instead of __uuidof(ISimplePgp). You can get this from the registry or you can usually find it in the OleCom Object viewer.

Like it or not, I'm right.

I'm not sure ISimplePgp is a valid argument to __uuidof. The compiler has to be able to find the GUID and I don't think ISimplePgp is stored in the registry. The ProgId and version ind. progid are in the registry and they reference the GUID of the class.

Glad it works. Smile | :)

Guess what Jason! This worked

HRESULT hr=p.CreateInstance(__uuidof(CSimplePgp));

CSimplePgp was my coclass Smile | :)

Another thing you have to do before use that code you have to do this:

use "#import" to import your dll in stdafx.h.You have to add something like this before //{{AFX_INSERT_LOCATION}} :

#import "C:\YourInterface.dll" no_namespace

then save and compile your StdAfx.cpp.After that locate your .tli and .tlh from your debug folder of ATL component project to your C++ debug folder .

I can't figure out why the caret disappears

3-Jun-02 23:01

I hid my edit box by ShowWindow (.., SW_HIDE), and then made it visible by ShowWindow (.., SW_SHOW) and
as a result, the caret is missing. The window has a focus because I can write in it, I can make selections and so on.
The only thing that bothers me, is that the caret is missing.

I had tried ShowCaret (), SetFocus (), it doesn't work.

Can you help ?

Re: I can't figure out why the caret disappears

3-Jun-02 23:20

I use straight WinAPI, but anyway thanks for interest, I have figured it out just a moment ago.

The solution is:

1. take the focus from an edit box, make it hidden

2. give the focus to the edit box again and make it visible

And the caret is here. Obviously, the caret is created and destroyed when the window gets and loses the keyboard focus.

PostThreadMessage failing

I use:

m_dw=_beginthread(ThP, 0, NULL); // successfuly
// ...
PostThreadMessage(m_dw, WM_APP+10, 0, 0); // unhappy

in a dialog-based MFC application.

The thread function is:
void ThP(PVOID pv)
{
MSG msg;

while (GetMessage(&msg, NULL, 0, 0))
{
AfxMessageBox("676767");
}
}

This doesn't work. Have any idea why?

_beginthread returns the thread handle, whereas PostThreadMessage requires the thread ID. Use CreateThread instead to create the thread, as it provides both.

Special Dialog screen to be programmed ...

Qadddd3-Jun-02 22:32

3-Jun-02 22:32

Hello,
I would like to program a kind of dialog screen containing a sort of header (with input area, text fields, buttons, radio buttons, ...) and, under this header, a zone where other dialogs can be displayed (one by one), these dialogs being selected with a tab bar .
To give an example of what I would like to do ... have a look at the dialog "System properties" or "Display Properties" of Windows.
Instead of having buttons on bottom of screen, I would have a header with various controls above this tab bar.
How can I do this kind of stuff in VC++ ?
Thanks in advance
DD

Customize mouse cursor

Rage3-Jun-02 21:35

Rage

3-Jun-02 21:35

Hi ! I´d like to change the mouse cursor of my app (MFC-Dialog). I looked in the Code Project FAQ, where it is written Put a SetCursor when handling the WM_SETCURSOR message.

So I tried this :

<br />
BOOL CTestDlg::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message) <br />
{<br />
HCURSOR Hcur=(HCURSOR)LoadCursor(AfxGetResourceHandle(),MAKEINTRESOURCE(IDC_CURSOR1));<br />
SetCursor(Hcur);		<br />
return CDialog::OnSetCursor(pWnd, nHitTest, message);<br />
}<br />

but this does not work ... what´s wrong ? BTW, is it the best way to do it ?

Thanks

RaGe
