i don't understand. what do you want? get the HWND to the task bar? get the process id to the process controlling the task bar?
Don't try it, just do it!

Hi Alxander,
Thanks for your immediate reply for the same. I need to get all top level windows to show the application icons on our product. In our product we are having one tooltip window, which is used for display all icons of top level windows (all taskbar application windows). It seems like ALT+TAB window. Samething like I need to create one window inside our product. For that I need to get all top level windows. Can u please help the same how to get top level windows.
Thanks in Advance

Are you creating the dialog at runtime, or toggling the min/max on and off buttons while the dialog is running?

there are 2 better ways. if you are using a dialog resource then change the dialog settings with the resource editor (there is an option for min/max button). the other way is to change the window style run-time.
DWORD dwLong;
dwLong = GetWindowLong( hWnd, GWL_STYLE );
dwLong |= WS_MINIMIZEBOX | WS_MAXIMIZEBOX;
SetWindowLong( hWnd, GWL_STYLE, dwLong );
Don't try it, just do it!

If in MFC, I think ModifyStytle() works the same way.
<code>
ModifyStyle(0, WS_MINIMIZEBOX | WS_MAXIMIZEBOX);
I have a little problem when making this style changes in run time tho. I placed it at the end of OnInitDialog() and the changes is made sucessfully. But at the first time the dialog appears, the MAXIMIZE and MINIMIZE icons (just the icons) are still on the menu bar, until the window is refreshed (e.g. switch to other dialog and switch back). Is this normal?

Is there a way of enumerating DDE Servers on a computer?
I would like to see which programs accept DDE messages on my local computer?

I have developed a Simple MFC GUI to allow a user to display and control an activity.
The program works fine on a PC with Visual Studio installed, but when I transfer the program
to a Laptop computer I get an Assertion Failure line 410 of file occmgr.cpp.
I built a Deployment & Install project to formally install the program, but still keep getting the same error. It works fine on a desktop PC without Visual Studio installed.
I was told that Assertions are present only in debug builds, and debug builds cannot be
and should not be deployed.
I have now built the application in 'Release' mode, but now need to install the .Net framework.
How do you do that?!?

Check out commercial installer such as InstallShield. It can package the .NET runtimes. You can give the user the link to download .NET Framework at MSDN.

it is because you built your application with Visual studio .NET, and the user that execute then don't have this framework.
run windows update and search for the .NET framework

I downloaded the dotnetfx.exe and installed it on the other PC but still get an Assertion Error on Line 410 of occmgr.cpp.
I think I built a 'Release' version of the program, as it reported during the duilt process that the .Net framework is required on the target machine.
What now!?!

|
|
|
|
P.S., if you still get an "Assert" error, that means you are still running the Debug version!

What do you need to do to build a Release Version?
I am struggling here!
|
|
|
|
|
There is a combo box near the menus that probably says "Debug". You should just be able to change this to "Release", and rebuild all, and it will work. Notice that the release build usually goes in a different directory, e.g.:
C:\Your Project\Release\YourProgram.exe
.. as opposed to the Debug, which goes in (unless you've changed it), something like:
C:\Your Project\Debug\YourProgram.exe
You'll notice the Release executable is about half the size as the Debug one.

Um.. if this is an MFC program, you should NOT need the .NET framework! That is only if you are using C#, managed C++, etc.
You can use the Dependency Walker to see what DLLs your code depends on. Perhaps there is something you are missing. (If your VS.NET didn't install it, you can do a quick Google search and find it.)
When you build in Release mode, what is causing you to believe that you need the .NET Framework? Is some error popping up somewhere?

I have now built a 'Release' version and no longer get the message that the .Net Framework is required.
I have installed the 'Release' version and after coping over some DLLs that were missing, when you double click on the icon nothing happens, no errors and apart from a 1/2 second the mouse changes shape to egg timer and back again.
They must be a simple answer to this problem, I am not doing anything unusual.

I am trying to get the list of domains AND LIST OF COMPUTERS under each domain.
I am getting domains when I use the parameter RESOURCE_GLOBALNET in WNetOpenEnum.
I am getting list of only computers when I use the parameter RESOURCE_CONTEXT in WNetOpenEnum.
But my requirement is I would like to get computers under each domain.
How should I achive this .This is the code.Pls tell me where I am going wrong.
NETRESOURCE res[10];
HANDLE hMain;
int x,y,i;
DWORD dwCnt = 0xffffffff;
DWORD dwSize;
DWORD dwRes;
dwRes = WNetOpenEnum (RESOURCE_GLOBALNET, RESOURCETYPE_ANY, 0,
NULL, &hMain);
dwSize = sizeof (res);
if (WNetEnumResource (hMain, &dwCnt, res, &dwSize) == NO_ERROR)
{
HANDLE hEnum;
dwRes = WNetOpenEnum (RESOURCE_GLOBALNET, RESOURCETYPE_ANY, 0, res,&hEnum);
while (dwRes == NO_ERROR || dwRes == ERROR_MORE_DATA)
{
dwCnt = 9;
dwSize = sizeof (NETRESOURCE) * 10;
dwRes = WNetEnumResource (hEnum, &dwCnt, res, &dwSize);
if (dwRes != ERROR_NO_MORE_ITEMS)

//Add this in to a list box. SendMessage (hwndList, LB_ADDSTRING, 0, (LPARAM)res[i].lpRemoteName) ;
}
}
}
WNetCloseEnum (hEnum);
}
WNetCloseEnum (hMain);

I have a base class that I have a copy construtor for, since I have dynamically allocated memory etc.
If I add a CList to my base class definition, and add the copying code to my base class copy constructor, do I need to also do the copying in my derived class??
class Msg
{ char *pszTst;
CList myList;
}
class tstMsg : public msg
{ }
msg::msg (const Msg &i_MsgToCopyFrom)
{
POSITION pos;
CIVAttrib attr, *pAttr;
if (i_MsgToCopyFrom.mCleanMsgBuffer != NULL)
{
mCleanMsgBuffer = new BYTE [i_MsgToCopyFrom.mCleanMsgBuffSize];
if (mCleanMsgBuffer != NULL)
memcpy (mCleanMsgBuffer, i_MsgToCopyFrom.mCleanMsgBuffer, i_MsgToCopyFrom.mCleanMsgBuffSize);
}
else
mCleanMsgBuffer = NULL;
pos = i_MsgToCopyFrom.myList.GetHeadPosition();
for (int i=0;i < i_MsgToCopyFrom.myList.GetCount();i++)
{
attr = myList.GetNext(pos);
pAttr = new CIVAttrib;
if (pAttr != NULL)
{
*pAttr = attr;
myList.AddTail(pAttr);
}
}
}
when i have a function call foo (tstMsg i_msg), will the copy constructor defined in the base class be called as well as the copy constructor of the derired class??
Thanks.

no, it can't, how would it know how to initialise the object from the derived class ?
you must provide in the derived class a new copy constructor.

No.. i meant if i made a call foo (tstMsg i_msg), would this call both the derived and the base class copy constructors??
|
|

|

you could define such constructor (see my following post to understand where these types come from) :
Manager::Manager(<font style="color:blue;">const</font> string& n, <font style="color:blue;">int</font> d, <font style="color:blue;">int</font> lvl)
: Employee(n, d), <font style="color:green;">
level(lvl) <font style="color:green;">
{
<font style="color:green;">
}
