- VB Scripts >> Problem with XCACLS.VBSHi
Is anyone using this? I down loaded it from Microsoft and I am having
trouble with the function to remove inherited rights and replacing them with
a copy of the rights
From reading the documentation, I am using /I COPY , but what happens is the
inherited permissons get removed, but nothing gets copied in - so subsequent
actions that rely on the parent permissions being copied are failing
(because the permissions aren't there)
Does anyone have any suggestions
Cheers

- MFC >> Resource limit?I am having a really weird issue that I can't figure out...
I am getting a unhandled exception in my application. Also a "a resource is
unavailable..." error. It appears to be related to opening a large number
of resources. I'm not sure.
I have a CDialog derived class that is embedded in a tabbed dialog type
control which is all part of a CFormView. This dialog view has a custom
control/grid that uses CStatic controls for the cells. Each instance of
the class creates around 250 CStatic controls. This has always worked
well, but recently I modified my code so that more than one of these
CFormViews can be open at a time.
On opening the 6th instance (they all use the same MDI template), the app
blows up. I can't track it down to a single line and I think that's
because it's an application-wide issue.
I don't think it's necessarily a problem with this particular CDialog over
the other ones in the tab dialog view. I think it causes the problem
because it creates so many controls. In fact it's not even this type of
view that is the problem. After opening 5 views, if I open a normal
CDialog that embeds the same grid control it blows. I'm pretty sure the
grid isn't specifically the problem just the source of the problem.
If I debug deep into MFC code it appears the CreateCompatibleDC is failing
in different places.
Is there a limit to the number of controls that can be opened at one time
(that would be odd). Is there a conflict between using the same resource
IDs over and over between views?
I have debugged for hours on this and am baffled. Any clues or direction
would be greatly appreciated!
Thanks much.

- Visual Basic [VB] >> Disconnected socket still connected! - What then?Hi, I have synchronous communications between a server and client. To save bandwith the connection must persist. So the socket must stay open and only be re-opened in case of communications failure. To simulate failure, the server disconnects the socket. However, the client socket parameter shows an open socket: socket.connected is true, socket. Active is true, socket.poll(1,selectRead) is true. When checking the MS class documentation, it is stated that socket.connected reflects the LAST status of the socket. So far, I have come accross many other programmers having the same problem. Some suggested of using the exceptions errors. But when connecting to a socket which is still open (according to VB.Net) while having the plug pulled out, the excpetion error one gets is, guess.......................Trying to connect on an open socket!! Have anyone found a way out yet? (That is appart from using other objects not designed in .NET)

- MFC >> OnIdle and UI threadHi,
I have an app that the Mainframe and the View are not in the same thread.
Then I find a problem, when the mouse is inside the View, the MainFrame's
OnUpdateUI handler is not call. Then I find it's because the main thread's
OnIdle is not called.
Why this happens and how to solved it?
Any comments are appreciated

- MFC >> COleControl::GetDCHi,
I am attempting to create a windowless control which will be transparent,
apart from animation that it draws to the screen in separate threads. I have
successfully worked out all the thread handling and synchronization thanks
to you lot but I am a bit stuck on the bit about the windowless control
getting a device context, especially as I want to paint to a buffer device
context and then copy that to the screen to avoid problems of bits of the
animation 'getting stuck' as they do when a control draws animates directly
to the screen. I've read the information in the link at the bottom of the
page, but does anybody know the answer to the following?
1) If I use the OLEDC_OFFSCREEN flag, I'm just a bit unsure as to what takes
care of the buffer device context and the copying of it to the screen. Does
the container take care of this (as is my guess), or does MFC take care of
it, or do I have to code that myself?
2) I understand how if OLEDC_PAINTBKGND is the parameter, the container
repaints the area of the window covered by the control with its own contents
in that area before passing the device context to the control in order to
allow it to paint to it, but does this happen if I just use OLEDC_OFFSCREEN?
Can I use OLEDC_OFFSCREEN | OLEDC_PAINTBKGND, i.e. do an OR operation to
specify them both?
Thanks for the help
Regards

- MFC >> Parent window cannot receive mouse click from child control.Hi there, that is strange. I have a form view inside a splitter window
that holds a slider bar. For whatever reason I cannot receive mouse
click messages when I click on the the control. I can receive the
messages when I click besides the control.
I was trying to look through newsgroups but I could find anything.
I know it must be something simple. Anyone that can help me out?

- Visual Studio C++ >> VS 2005 Compatibility ProblemPlease point me to a more appropriate group if there is one.
Thanks.
We have a native Win32 API console program built with VC++ and VS
2005. It will run on any XP box with VS 2005 installed. Then,
we packed it and the needed DLLs up and put it on a server. It
turns out it will run fine on Windows 2000 server but won't start
at all on a Windows 2003 server. The error is "The system cannot
execute the specified program." We get the same thing when
testing on an XP box that DOESN'T have VS 2005 installed.
Any ideas?

- Visual Basic >> GetDriveType problemNot really a problem but more of a question.
I see how to use the GetDriveType API to get
the type of drive for a letter such as c:\
Is there a way to get the media type inside a drive.
In particular is there a way to tell if a disc is a CDR
or a DVD-R.
Thanx

- Visual Studio C++ >> Self deleting classHi,
Imagine:
CSomeClass* c = NULL;
c = new CSomeClass();
delete c;
c = new CSomeClass();
delete c;
So I must call delete c; to clean up memory.
However, instead of doing it like so.. isn't it equally valid to make class
self deleting?
So, if I do this:
class CSomeClass
{
CSomeClass();
virtual ~CSomeClass() { delete this; }
}
can I then simply do this?
CSomeClass* c = NULL;
c = new CSomeClass();
c = new CSomeClass();
What happens when I reassign the valiable to new instance? Will CSomeClass
self-delete itself at that point, or when application terminates?

Visual Basic [VB] >> Reflection and Menu Merging in MDIs
We have an MDI application that looks for forms in which a common interface
has been implemented. We can instantiate the forms and display them as
children of the mdi and use the functionality on them.
The problem is that the menus from the child forms don't show up. They
don't even show up on the
form itself, much less merge with the mdiparent menus
We have changed the modifiers on the menu and on each item in the menu to
public so they can be seen outside the assembly. We have tried not making
the form an mdichild and using it as a stand-alone application (still
instantiated by the mdi, although not as a child). The child form does
appear in the 'windows' list as a child of the mdi.
Is there any way to make available to the mdi, the menu on a child form
instantiated through reflection?

- Visual Basic >> Use XSD to get data types for XML elementsI am using VB6.
I am receiving an XML file and an XSD file.
I understand I can use the XSD file to validate the XML file, but is
it also possible for me to use the XSD file to give me the data types
of the elements in the XML file?
When processing the XML file, I know the name and the value (e.g.
<FirstName>Richard</FirstName>, <Amount>1.23</Amount>).
The XSD has the datatypes defined for each element.
What I want to do is, while processing the XML file in my VB program,
also be able to get the data type for that element.
Thanks for any help.

- Visual Basic [VB] >> System.Diagnostics.ProcessHello All,
I have posted previously regarding the above assembly. I have created a 2
classes and an interface to mask the complexities of using the above
assembly. The purpose of the interface is to allow one to create any UI
that they wish to search for files using the program find.exe. All the user
has to do is implement the interface and instantiate the FileFinderControl.
Class: ProcessController (has two threads that montor StandardOutput and
StandardError, and two delegates and events to pass this information on to
the FileFinderControl which manipulates the IFileFinder Interface)
Class: FileFinderControl (manages the interactions between the
System.Diagnostic.Process and the IFileFinder Interface)
Interface IFileFinder (abstracts the UI implementation so multiple UIs can
be created)
My problem is that I cannot get this architecture to run without the
ProcessController stepping on memory and causing a fault. I can implement
System.Diagnostics.Process seperately but only within my GUI. In the GUI
implementation I use the Invoke method to communicate across the thread but
it does not work when implemented through an interface.
Any Suggestions?
Thanks,
Dan

- Visual Basic >> Do Not Show Box AgainHi All,
I have a small form that appears at the start of my program that allows the
user to fix certain parameters that are lised in Combo boxes in the main
program before starting. This works OK but appears everytime the program is
first run.
What I would like is for there to be a Check Box that askes the question "Do
not show this box again" and fixes the selected parameters for all time in
the main programs Combo boxes, and does not appear again.
Can this be done?

- Visual Studio C++ >> Class InitializationDumb question,
Does C++ auto-initialize (zero out) data members in a class? Only Class
based members? arrays? or should I always initialize them in the
constructor? I mean I always do and have, but at times it becomes
tedious and I always wonder if it is truly necessary, so I am just asking to
finally get it out of my head! <g>
Many times I'll just create a struct with all my class data members
(non-class based struct fields) and then just have a ZeroMemory() in my
constructor. This way I don't have to worry about initialization when I add
new fields to the struct. But if I need a CString in the struct, I have to
remember that I can't use ZeroMemory on the struct. So that's part of the
reason why I am asking.
Thanks

- Visual Studio C++ >> self debug informationHello,
I've implemented the following things on another platform, and I'd
like to know whether they could be done with VC++:
- when an uncaught c++ exception occurs, the program prints its
type, and if it's derived from my own exception, it prints an exception
stacktrace (the stacktrace stored in the exception object) - like in java.
Is there anything like abi::__cxa_current_exception_type()?
- when a program causes general protection fault, division by
zero, etc., the program prints the stacktrace
- these things can be added to an already working program without
serious modifications: only a call to initializeSelfDebug() is needed at
the beginning of main()
The stacktrace contains IP address, source:line information.
These things should be available without Visual Studio installed (VS
isn't installed on the machines of testers/users).
When the program crashes, these things give us a lot of valuable
information instead of the usual "your program crashed-click to OK"
messageboxes.
Thanks,
Geza
ps: I'd like to avoid the
int main() {
try {
original_main();
} catch (MyExc &e) {
e.printStackTrace();
} catch (...) {
print("unknown exception occured");
}
}
because in some scenarios it doesn't work (for example: a dll plugin)
