Have you checked if the connection is being closed somewhere prematurely in your code while it is still being used?

Is there any way of knowing the windows of a process. I want to write a win32 program that will tell if a process has any visible window or if a window minimised to system tray.

GetWindowThreadProcessId will give you the process id of a window.
You can do EnumWindows to get all visible and hidden windows.

I don't think you can do it the other way around.

I’m getting a assertion in below code. What could be the prolbem.

bool AxControl::CreateOleClientInstance(CLSID clsidActual)
{
	clsid = clsidActual;
	AfxEnableControlContainer();
	pDoc = new COCXDocument();
	pDoc->OnNewDocument();
	pClient = new COCXClientItem(pDoc);
	CoInitialize(NULL);

	pClient->CreateNewItem(clsidActual);
//Assertion is thrown in above line 
//File: f:\sp\vctools\vc7libs\ship\atlmfc\include\afxwin1.inl
//Line: 29
//{ ASSERT(afxCurrentAppName != NULL); return afxCurrentAppName; }

	pClient->m_lpObject->QueryInterface(
			IID_IDispatch, (void**)&m_lpObjectdispatch);
	
	return true;
}

As My application is Build in C++\CLI, and I was using MFC code in that, the application name was not set. To fix the Assertion, I used

afxCurrentAppName =(LPCTSTR) "Dummy App";

Hello,

Once I make an object throuh CRuntimeClass how do I pass parameters to this object.

CMDIFrameWnd* pFrame = STATIC_DOWNCAST(CMDIFrameWnd,AfxGetApp()->m_pMainWnd);

pFrame->CreateNewChild(RUNTIME_CLASS(TableF),IDR_KTYPE, m_hMDIMenu, m_hMDIAccel);

how do I access object made with CreateNewChild()

If you check out the documentation[^] you can see that it returns an CMDIChildWnd pointer...could that be it?

Being bought a beer always sounds like a good plan to me!

Maybe I'll try and arrange a Sweden CP meet late summer... could be fun.

But my plans are very chaotic right now, as I'm sure you'll understand, so that sort of thing will havge to wait a couple of months.

By reading the documentation for the CreateNewChild method.

MSDN wrote:

CMDIChildWnd* CreateNewChild(
CRuntimeClass* pClass,
UINT nResource,
HMENU hMenu = NULL,
HACCEL hAccel = NULL
);

The function returns the new child that it has created. You should almost always pay attention to return values...
You can that cast it to the TableF type, and call as many functions as your heart desires.

Hope that helped!

Set maximum length for Windows System password

Hi,
I've tested out through a TEST.exe the method "NetUserChangePassword()" and it is taking '63' as the maximum password length for both Standalone & Domain connected systems. If the password is more than 63 then we get error as ----
"Unable to update the password.The value provided for the new password does meet the length,complexity or history requirement of the domain (1325)"

Can we set more than '63' as password length for Windows server as well as Standalone machines through any API programaticaly ??

please let me know as soon as possible.
Thank you in advance.

Bye...
