Thank you!
Problem solved...

Ok, thats why it worked in another application... (The handler was present in the MainForm)
Never thought of why, probably because it had a handler then...
Thanks alot..

Hi,
I've got a problem compiling my code on some machines. The code in questions uses
#include <cdosys.h>
On my machine, that's not a problem, it compiles and links without a hitch. On other machines in the office I get the following output from the compiler:
C:\PROGRAM FILES\MICROSOFT SDK\INCLUDE\cdosys.h(523) : error C2061: syntax error : identifier 'RecordCreateOptionsEnum'<br />
C:\PROGRAM FILES\MICROSOFT SDK\INCLUDE\cdosys.h(532) : error C2061: syntax error : identifier 'RecordCreateOptionsEnum'<br />

c:\develop\proj\myfile.cpp(578) : error C2039: 'Update' : is not a member of '_NoAddRefReleaseOnCComPtr<struct CDO::ADOFields>'
Anyone got any ideas what the problem could be? Both machines have the latest SDK, properly referenced, and the latest service packs installed. Both machines are WinXP pro and the dev environment in MSVC 6.

it is clearly a SDK problem.
it seems that the sdk is not well referenced (even if you believe it is).
now, how to resolve this, i'm struggling.
i don't know at all.
perhaps if you provide more infos... (computers differences)

As you have the proper files on both machines, I'd suspect the ordering of the include directories.
One PC may look in the platform SDK directory first, and find the header there, and the other PC
might look in the visual studio include directory first, and find the header there...
That problem might not be with cdosys.h, but with a header *it* includes. One version defines _Stream
etc, and the other does not.
In VC6, look at Tools | Options, Directory tab, and pick Include on the Combo box. There are black
arrows to rearrange the order.
Have a look at the working machine, and replicate the order on the not-working machine!
Good luck,
Iain.

What is the difference between an accelerators and a hotkey?

toxcct is 90% right. People use the two names interchangably. Hot Key is a common user name
for an accelerator.
Being pedantic...
An accelerator is a part of an accelerator table. (LoadAccelerator, TranslateAccelerator, etc.) It only works when your application has the keyboard focus.
A Hot Key is a a system wide key (RegisterHotKey, UnregisterHotKey). When pressed, windows send a WM_HOTKEY message to you. It works all the time. You could use it to make a certain key combination do something even when your application is hidden. (eg. screen capture, etc). I would not recommend having it active all the time, as it may collide with accelerators of other applications.

Some also confuse one or both of those words with a "mnemonic", which is the underlined character you get on dialog controls allowing you to focus or activate that control using the <ALT> key along with the key of the underlined character.
They (mnemonics) are also used on top-level Menus and Menu Items (although you do not need to use the <ALT> key when a menu or menubar is active).
Peace!

Hi all,
I'd like a little help. I am writing a Setup program and have come up against the problem of installation over a network. The program currently works perfectly installing on Windows machines locally but I am trying to consider how a network admin might install across a network. Currently the setup would require individual installations on each machine due to the fact that local registries are set by the setup program.
I guess what I'm asking is, what is best? Do network admins usually install systems individually or is there a method of cascade installation which can be applied?
Many thanks

In windows this is the case. But there are tricks we sometimes use to do a full install of all applications then mirror the disk and use special software to make windows create a new uid for the machine. However this generally only works on very similar systems (same hardware).

Thanks for the feedback. My favourite kind of problem... A problem that's not a problem. Looks like I'm onto testing 
Cheers

One thing you can do to make it less work for network admins is to allow the media to be copied (not installed) to a server share and then installed individually from there to each pc instead of having to carry a cd around to 1000 computers. In some places (my hospital) we have computers without cds so allowing pcs to be installed in this way is essential.

Something like:
if (bFound)
{
if (it's a popup window)
SetForegroundWindow(handle to the popup window);
if (it's an icon)
ShowWindow(handle to the popup window, SW_RESTORE);
return FALSE;
}

thanks david, but firstly, Alok answer satisfied my plainly (with code), and secondly, your sample is not exactly what i need.
anyway, i apreciate.

Strange, as it has always worked for me. After you find that the mutex exists, indicating that the application is already running, it's simply a matter of restoring the window.

hum well, how do you get handle to the popup window ?

Use EnumWindows().

This is how I limit my apps to a single instance and activate the first instance if another is run.
HANDLE hm = CreateMutex(NULL, TRUE, "Mutex Name");<br />
DWORD dw = GetLastError();<br />
if(dw == ERROR_ALREADY_EXISTS)<br />
{<br />
SetForegroundWindow(FindWindow("ClassName", "WindowName"));<br />
return(0);<br />
}
There are probably better ways but this is the simplest I know and has always worked just fine.

interesting code.
but what do ClassName and WindowName represent exactly in your above line code ?
<code>SetForegroundWindow(FindWindow("ClassName", "WindowName"));</code>
thanks in advance.
