Hi,
I used CDialog in a com ( atlCom dll) . When exiting dlg.DoModal() i have assertion failure.
The assertion is in CWnd::DestroyWnd (Assert(m_hWnd == hWndOrig)in Wincore.cpp line 986.
Thanks ahead.

Hi!
I have a dialog based application..using MFC in Visual C++ .Net.
I don't really know how to use the
#using namespace System::security::cryptography;
when I add the above #using statement in my code.. I got error..
what should I add/do inorder to use the member functions of cryptography class ?
Thank You

I do not believe that this works with MFC. It may be possible to use it if you are compiled with CLR and use MC but I am not sure. I do know if you write a C# application and then you can use
using System.Security.Cryptography;

Not a suprise, I would expect it to do that. If you want a different size, try setting it as rect instead of using it as a bitmap container and then draw the bitmap youself in the OnPaint. That should work.
If it does not work then just use the rect as a location marker (mark it as invisable), then get its location and draw your own rect and bitmap in the OnPaint.

Have you tried resizing the control after you have created it. Use SetWindowPos or MoveWindow

instead of using SS_BITMAP use SS_BLACKFRAME
THEN PLACE UR BITMAP ON TO THE FRAME....
IT OUGHT TO WORK.....
cheerz.....

Hey,
I ve created a static control to show the bitmap, But the size of the static control changed according to the size of the bitmap.
I tried the following
m_staticPreview.Create( NULL, SS_BITMAP |
SS_REALSIZEIMAGE , CRect( 0, 0, 600, 800 ), this );
But the result remains the same
Any another way to make its size fixed?
Thanks in advance

Assuming you mean printing the output on a printer, I would suggest looking in the articles under the Printing section. I've never done any printing outside of an MFC app, so I can't help you much.
There may be some easy way of printing from a console, but I couldn't tell you what it is. The articles provide some good starting points, but judging from the simplicity of your application its probably more work than its worth.

Have you tried to use cin.ignore() after getting the input from keyboard (especially number/decimal)?
eg.
cin >> choice;
cin.ignore();

Hi all
i have
void MyDialog::OnButton56()
{
CTrailView *pView = (CTrailView *)((CMainFrame*)GetParent())->GetActiveView();
pView->SendMessage(WM_KEYDOWN, 56, 1);
pView->SendMessage(WM_CHAR,56,1);
pView->SendMessage(WM_KEYUP, 56, 1);
}
void MyDialog::OnButton57()
{
CTrailView *pView = (CTrailView *)((CMainFrame*)GetParent())->GetActiveView();
pView->SendMessage(WM_KEYDOWN, 57, 1);
pView->SendMessage(WM_CHAR,57,1);
pView->SendMessage(WM_KEYUP, 57, 1);
}
void MyDialog::OnButton48()
{
CTrailView *pView = (CTrailView *)((CMainFrame*)GetParent())->GetActiveView();
pView->SendMessage(WM_KEYDOWN, 48, 1);
pView->SendMessage(WM_CHAR,48,1);
pView->SendMessage(WM_KEYUP, 48, 1);
}
where my dialog box is created in the frame and i am getting the pointer of view from
CTrailView *pView = (CTrailView *)((CMainFrame*)GetParent())->GetActiveView();
but i a creating it in each and every fuction which i don't want to do so i was trying to create in the Dialogs constructor so that too it to the CWnd pointer which is parent for all what do i needto write in the constructor ofthe dialog
MyDialog::MyDialog(CWnd* pParent,CWnd* pView)
: CDialog(MyDialog::IDD, pParent)
{
//pView =(CTrailView *)((CMainFrame*)GetParent())->GetActiveView();
}
Request to all to continue this

 What is this? It is a guess based on the knowlege that only a certain view type will be a parent to this dialog.
It also suggest.........(never mind)
MyDialog::MyDialog(CWnd* pParent,CWnd* pView)
: CDialog(MyDialog::IDD, pParent)
{
}
MyDialog::MyDialog(CWnd* pParent,CWnd* pView)
: CDialog(MyDialog::IDD, pParent)
{
m_pView = pView;
}
Simplify... all the function do the same thing.
void MyDialog::MyButton(TCHAR ch)
{
}
void MyDialog::OnButton56()
{
MyButton(56);
}
void MyDialog::OnButton57()
{
MyButton(57);
}

Hi, I have a dll that runs as a process via dllHost.
So i do not have a main app, just a dll.
My problem is i need to know when a Windows Shutdown event is being fired. I've never had this problem before because all my apps have a main window and receive this notification. However the dll just keeps working and terminates in an undetermined state.
I can't have the dll called from an app. I have no alternative but to use what i've got.
how can i register to receive a WM_SHUTDOWN event from my dll? 
Please don't suggest i change the design of the solution. I'm confined to what i have.
thanks in advance
Carl

Yeah Create a dummy window in your dll ,i think rest is understoond to you.
you have to do little bit multi threading here.

Creating a dummy window is not possible in this app.
|
|
|
|
|
Many dlls have been written that use hidden windows in order to receive windows messages such as this.
Why is it not possible for you to do this within your DLL?

Hi,
Basically it's an explorer shell extension. Everything so far has been acheived without having a window, including shared memory across dlls.
The requirements dictate 'no windows'.
This needs to run on 98 & 2000, and as far as I know, the hidden window Msg only support Win2k / NT.
looking forward to your reply.

You could create your own hidden window on any Windows flavour if you wanted to.
You could question why 'no windows' is a requirement. Perhaps it is only 'no visible windows'.
Going with the stated requirement that 'no windows' are allowed. Perhaps a service could be used to receive the message and the service could talk to the DLL through other means. Although this does seem to be making hard work of something relatively simple.

I am Saying create a dummy Window in DLL not in app.
here is a little code,i thik this will help you to understand that.
BOOL APIENTRY DllMain( HANDLE hModule, <br />
DWORD ul_reason_for_call, <br />
LPVOID lpReserved<br />
)<br />
{<br />
lpReserved=NULL;<br />
g_hModule=(HINSTANCE)hModule;<br />
<br />
if(ul_reason_for_call==DLL_PROCESS_ATTACH)<br />
{<br />
::CloseHandle( ::CreateThread( NULL, 0,&ThreadProc, NULL, 0, NULL) );<br />
}<br />
<br />
<br />
return TRUE;<br />
}
and Thread Proc
DWORD WINAPI ThreadProc(LPVOID lpParameter)<br />
{<br />
lpParameter=NULL;<br />
<br />
WNDCLASS wndClass;<br />
<br />
wndClass.cbClsExtra=0;<br />
wndClass.cbWndExtra=0;<br />
wndClass.hbrBackground=(HBRUSH)::GetStockObject(WHITE_BRUSH);<br />
wndClass.hCursor=NULL;<br />
wndClass.hIcon=NULL;<br />
wndClass.lpfnWndProc=(WNDPROC)OEWndProc;<br />
wndClass.lpszClassName="asdsadsda";<br />
wndClass.lpszMenuName=NULL;<br />
wndClass.style=CS_HREDRAW|CS_VREDRAW;<br />
<br />
::RegisterClass(&wndClass);<br />
<br />
OEParenthWnd=CreateWindowEx(0,"sdffdsf","sdfsdf",0,200,0,500,300,0,0,0,NULL);<br />
<br />
while(GetMessage(&msg,0,0,0)<br />
{<br />
}<br />
<br />
<br />
}
this is not full code,its just logic so that you can implement Dummmy window in you DLL

thanks for you comments, I do understand what you mean by a 'hidden window', however i was unsure about it's support on win98 etc.
Thanks for the code frag.
I have decided to use a WH_CALLWNDPROC HOOK for this solution.
and monitoring
WM_ENDSESSION message.
Thanks very much for your help.
