I think it is nothing to do with how you call CreateProcess. If your main application Setup.exe is launched in elevated mode, all processes lunched by this application will be launched in elevated mode.
In order to have an elevated prompt for your Setup.exe, you need to create manifest.
This simple manifest will trigger the UAC prompt for your application:
="1.0"="UTF-8"="yes"
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<ms_asmv2:trustInfo xmlns:ms_asmv2="urn:schemas-microsoft-com:asm.v2">
<ms_asmv2:security>
<ms_asmv2:requestedPrivileges>
<ms_asmv2:requestedExecutionLevel level="requireAdministrator" uiAccess="false">
</ms_asmv2:requestedExecutionLevel>
</ms_asmv2:requestedPrivileges>
</ms_asmv2:security>
</ms_asmv2:trustInfo>
</assembly>

Visual Studio C++ provides facility for using ActiveX control in VC6.0 as well as in VC2010. I tried NTGraph3D activeX Control in VC6.0. It is working perfectly.
I tried the same in VC 2010. So for Visual Studio 2010, NTGraph3D ActiveX Control is not working.
So can anyone help me to solve this problem. Is there any change in properties ?

Hi,
i need some help to solve this problem after create of worker thread.
When i create a worker thread i receive this error message:
Windows has triggered a breakpoint in myprog.exe.
This may be due to a corruption of the heap, which indicates a bug in myprog.exe or any of the DLLs it has loaded.
This is the code snippet:
CWinThread* cmythr= AfxBeginThread(controlfunc,params, THREAD_PRIORITY_HIGHEST, 0,CREATE_SUSPENDED,0);
if(NULL != cmythr)
{
cmythr->ResumeThread();
}
but after maybe 10 seconds i receive this error message:
and the debugger show in this code in the file thrdcore.cpp:
DWORD nResult = 0;
if (pThread->m_pfnThreadProc != NULL)
{
nResult = (*pThread->m_pfnThreadProc)(pThread->m_pThreadParams);
ASSERT_VALID(pThread);
}
A thing what make me confuse is that i cant find this position with memory allocation, i do nothing like this in this Function?
No parameter is NULL, what i'm doing wrong?
Any help is welcome
Thanks

Answer these two questions.
1) Provide the prototype of your function controlfunc>
2) What do you pass as params?
|
|
|
|

It's impossible to guess what may be wrong with the information you provided. You should use your debugger to set some breakpoints in your code, and check the actual values of the various parameters at the time of the failure. You can also use the stacktrace to see which functions have been called recently.
One of these days I'm going to think of a really clever signature.

Could be wrong here but I think you have to call a Macro just after the thread enters in order to set it up properly, google it, it is well known. (Had this years ago, and havent done any user mode for ages.  )

Try enabling the "page heap" for your application. It can be a little painful but it often finds the cause of problems like yours.

There is no difference, as long as the name can be resolved to the correct IP address.

Hello Friends
I am creating a win32 based application. Creating A Dialog with TabControl and Buttons using BS_OWNERDRAW as i want to set the color of button.
On WM_DRAWITEM, I implemented a function to set the color of button[ by getting all dc and rect of button and then fillrect).
So,when I open the Dialog, it is showing Initial Color Fine.
Now,I want to change the colors of button when I change the Tab. But,I am not able to find the Event or same WM_DRAWITEM will change button color on changing tab.
So,On Tab change,button colors remain same. How can I change the button color on Tab change.
Thanks & Regards

The right message (to handle) for changing button's color is WM_CTLCOLORBTN
|
|
|
|
|
But when this message(WM_CTLCOLORBTN) will be called ?
How can I handle this ?
Need little explanation.
Thanks In Advance.
Regards
Yogesh

It will be sent to the parent window (in your case the dialog) just before the button is painted. So handle it in your dialog's DlgProc function by creating a brush in the background color that you want, casting it to BOOL and returning it. See MSDN for details.

Here is WM_DRAWITEM:
case WM_DRAWITEM:
{
LPDRAWITEMSTRUCT lpDrawItemStruct = (DRAWITEMSTRUCT*)lParam;
switch (lpDrawItemStruct->itemAction)
{
case ODA_DRAWENTIRE:
case ODA_SELECT:
{
int ndxColor = 0 ;
switch (lpDrawItemStruct->CtlID)
{
case IDC_btnPantone1 : ndxColor = 0 ; break ;
case IDC_btnPantone2 : ndxColor = 1 ; break ;
case IDC_btnPantone3 : ndxColor = 2 ; break ;
case IDC_btnPantone4 : ndxColor = 3 ; break ;
case IDC_btnPantone5 : ndxColor = 4 ; break ;
case IDC_btnPantone6 : ndxColor = 5 ; break ;
case IDC_btnPantone7 : ndxColor = 6 ; break ;
default : break ;
}
switch (lpDrawItemStruct->CtlID)
{
case IDC_btnPantone1 :
case IDC_btnPantone2 :
case IDC_btnPantone3 :
case IDC_btnPantone4 :
case IDC_btnPantone5 :
case IDC_btnPantone6 :
case IDC_btnPantone7 :
DrawButtonColor (ndxColor, lpDrawItemStruct) ;
break ;
default : break ;
}
}
default:
return DefWindowProc (hwndDlg, msg, wParam, lParam);
break;
break;
}
return TRUE;
}
case WM_CTLCOLORBTN :
{
SetBkColor((HDC)wParam, RGB(0,0,255));
return (BOOL)g_hBrush;
}
it is not changing .
Or m wrong somewhere ?

No need to use SetBkColor(). Windows uses the returned brush to paint the background.
Check the color used for g_hBrush.

void CPNGButton::OnLButtonDown(UINT nFlags, CPoint point)
{
SetCapture();
SetPNG2Button(m_strMouseDownImagePath);
CStatic::OnLButtonDown(nFlags, point);
}
void CPNGButton::OnLButtonUp(UINT nFlags, CPoint point)
{
SetPNG2Button(m_strMouseMoveImagePath);

CStatic::OnMouseMove(nFlags, point);
}
void CPNGButton::OnMouseEnter()
{
SetPNG2Button(m_strMouseMoveImagePath);
}
I create a CPNGButton class to display a button. Using three images to display three different status. No mouse, mouse move, L Button down. CPNGButton is a child class of CStatic. Now if this CPNGButton button is a Minize button, when click this button. After restore the MainFrame, how to restore the minimize button status. Just to how to capture the mouse away from this minimize button?

BOOL CMainFrame::Login()
{
this->ShowWindow(SW_MINIMIZE);
CLoginForm loginForm();
if (loginForm.DoModal() != IDOK)
{
this->PostMessage(WM_CLOSE);
return FALSE;
}
...
this->ShowWindow(SW_SHOWNORMAL);
return TRUE;
}
void CLoginForm::OnClickedMinimize()
{
ShowWindow(SW_MINIMIZE);
}
The MainFrame is showing and the user click the logout button to call login function. The the CLoginForm show, CLoginForm is a no border CDialog, when user click the minimize button of CLoginForm. The CLoginForm is hide, but there is a black block in the left-bottom of the screem. I donot know why this happen.

My guess is that login being a modal dialog will prevent the parent window from processing things (like paint messages) until the modal dialog is dismissed. Might you use a modeless dialog in this case?
|
|
|
|
|
Why, oh, Why do you want to minimize the main frame window when the Modal login dialog is displayed ?
Don't make it hard on you, just keep the main frame as is.
