Path up to parent directory should be valid to make call to CreateDirectory succesfull. In your case,
folder 'A' should be present to create folder 'B' in it.

hi i need help in the case of Tree View Control with Check Box.

my problem is whenever i select a check box and click close/cancel(within the dialog box) and come back to check box selection i need the previous tree state
to be retained,ie if i selected "parent1" and closed it when i come back again to the dialog box i will get the new dialog where previous state is lost.

status should be retain till the end of the close of main window.
here is the code with which i am trying . but it dint work

/*if(PreviousCheckStatus)
{
TVITEM item;
item.mask = TVIF_HANDLE | TVIF_STATE;
item.hItem = hParent1;
item.stateMask = TVIS_STATEIMAGEMASK;
item.state = TVIS_SELECTED ;
SendDlgItemMessage(hWnd,IDC_TREE1,TVM_INSERTITEM, 0, (LPARAM)(&item));
}
*/

i will send the complete program, if any body have the solution for the problem.
please mail me to rameshsms@rediffmail.com

What does this line mean? Whether the global variable is not showing the prev status or the control on the dialog?
If 'the control' is ur answer then ... are u setting the control according to the value of your global variable in the dialog's OnInitDialog()?

i am checkin the global variable in WM_INITDIALOG.just for the sake of testing one global variable is being maintained for each checkbox.if the variable has true value, then trying to set the corresponding checkbox as selected.

when i run the app for the first time, obviously the global variable will have value 0.
consider i select a check box(corresponding global variable is True now).i ll close the dialog n open it again.here that peice of code i given above is not working.
could u get me ur mail id so that i can send u the complete program ??

Use ShowWindow() for that purpose.

Can you get handle of window in question ? Use FindWindow for that. And use ShowWindow for completing your tasks.

Hi,
I'm facing a problem with the COM Dll that is also written by us.
I have a COM Dll, which uses another two dlls. And for UI I have another application which uses the COM Dll(The application is a Win32 application without MFC Support).
When the COM Dll is built in the release mode, CoCreateInstance method causes the message box "User breakpoint called" to be popped up.
In fact the CoCreateInstance does so many other things like initializing the communication, initializing the drive..etc.
When the Dll is built in the release mode, it causes no problem.
The problem I've identified is in the statement where delete <someobject> was being called.

The interesting fact is that the problem does not araises with the applications with MFC Support. My one perticular application is without MFC Support. The COM Dll is built with Static MFC support.

Another thing is that, to make tha applicaion up the COM Dll should be built with the Shared MFC Dll support. But when I make COM Dll with shared MFC, other applications(those were built with MFC support earlier) does not work.
I'm confused how the MFC support for the COM Dll affect the behaviur of the applications. Please provede me with a solution.

Thanks and regards,
Raja Pratap Reddy

Hello Friends.
When I click on the Item in the listCtrl, next Item should also be selected.
I did it by using SetItemState() method.
When I select item it works fine i.e next item is also selected but when
I click on that selected item,ideally,the item next to it shld be selected.
But it only flashes...I mean it is selected and next moment it gets deselected by itself.
Here is my code ..
Its written in the function of NM_CLICK Message.

CODE :
BOOL l_bRet = 0;
POSITION pos = m_SelList.GetFirstSelectedItemPosition();
int index = (int)pos;
for(int j=(index-1); j

Hi All,

I have a snap-in application which was wriiten for MMC 2.0 using MMC
2.0 SDK. On porting the sample application on Longhorn which has MMC
3.0 by default, I get the snap-in error asking whether I need to
shutdown mmc application.(" MMC has detected an error in snapin.....").
I was not able to find any C++ samples along with MMC 3.0 SDK. Are
there any additional callbacks that I need tp include to provide
support for MMC 3.0? If yes, where from I can get them? Any pointers to
the C++ samples for MMC 3.0? Any help on this would be appreciated.

Not getting connected to root\wmi namespace

15-Jan-07 17:59

Hi,

I have implemented in the code for wmi.

It works just fine for cimv2 workspace and Win32_OperatingSystem class.

It is not working for any other class (i need Win32_CDROMDrive) in cimv2 namespace. Not even working for root/wmi namespace.

part of my code is :

IWbemClassObject *pclsObj = NULL;
ULONG uReturn = 0;

while (pEnumerator)
{
HRESULT hr = pEnumerator->Next(WBEM_INFINITE, 1,
&pclsObj, &uReturn);

if (FAILED(hr)){
AfxMessageBox("Failed");
}

if(0 == uReturn)
{
break;
}

}

It successfully connects to the namespace but later, it gets uReturn as zero always and breaks.

I tried BeginEnumeration as well before executing 'next'.

(For wmi namespace, 'hr' fails after connecting to the namespace.)

Is there anything else that I need to do?

Please help.

Thanks ,

Manasi

Here[^] is an example of Win32_CDROMDrive of course in C# (I think you can understand it)
only see (foreach(datatype variablename in Arrayname) )

(1)datatype is type like char/int,...
(2) variable name for detect elemets in array
(3) arrayname name of Array
