Why the Spin button in MFC behaves oddly. It should increment the buddy value when we press the UP button and decrement by pressing DOWN. The button functionality is Invert of what it should be.

You have to set the range using SetRange(). If you do not set the range, the default is to have the maximum set to zero and the minimum set to one hundred. This gives you the inverse functionality you are experiencing.

because spin controls are constructed from 100 to 0 by default.
use CSpinButtonCtrl::SetRange() to set the lower/upper bounds of your spin

I got someone to code me a control in VC++. The program requires me to go through a process by which something gets written to the registry. Any idea why this is required?
Thanks.

i think That Program using Registry for storing some temp value for later use.

for that you have to read the code ,why he is implementing that.may be to handle registry is very easy

It's by design. Beginning with Win95, Microsoft deprecated the concept of using .ini files to initialize program functions, and started pushing the concept of the Registry as a central repository of program information and initialization. Controls often require a few initial settings to be implemented and, consistent with the new model, this requires adding information to the Registry whenever a new control is added to a system.

Thanks for the answer. ![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)
But is it possible to do without using the registry at all? What I asked for is that icons be associated with unique functions. This is so that somebody doesn't manage to associate (deliberately or inadvertently) the diskette icon with the 'delete' function, for instance. Of course, that would mean that I have already used the diskette icon for the 'save' function. So, the diskette icon should neither be overridden nor be associated with a second function. Is this what the registry help accomplish? Can it be done without any dependency on Microsoft OS functionality and purely in VC++?
Thanks.
PS. In case you are wondering, the control lets me build a variety of toolbars from existing icons/functions and to whose library I may want to add more icons/functions.

How could I handling the process of 'Program closing' using Visual C++ (MFC)
I want the program to 'decide' how to quit or when to quit.
|
|
|
|

You have to override the WM_QUIT and WM_CLOSE messages. The WM_QUIT message is the one that terminates the entire application. WM_CLOSE is sent when exiting a window such as a dialog.
An example of how to manually quit the program would be
PostMessage(WM_QUIT, 0, 0)
Similarly WM_CLOSE can be used as well.
Hope that helps.

It doesn't work when I tried to override WM_CLOSE message in my view class. It seems that the system did not send WM_CLOSE message to my CView class when the prgram started to terminate.
|

Hmm. I'll try to help you out more, although I don't know that much about overriding those messages as I've never done it before.
I've only worked with closing the program in a dialog based app. The code I posted before should work for manually closing the program. I don't see why it would be any different in an SDI. I'd suggest working with the WM_QUIT message first since that is the message sent when the program terminates. As far as I know the WM_CLOSE message is used if you have for instance a pop-up dialog and want to close it, so it shouldn't be sending any WM_CLOSE messages upon termination of the entire program.

I used spy++ to trace messages of my program, but did not get any WM_QUIT message.
So I'm afraid if it would take effect if I work with the WM_QUIT message.
|
|
|
|

Well I'm pretty sure that's what happens when you press the big orange 'X' button.
Try this and you'll see what it does. In any of the drop down menus you have create an option called "Quit" and in the code just put
PostMessage(WM_QUIT, 0, 0);
That will quit the entire app.

Hello all. I'm in a big problem. I'm opening a file and I'm getting the size of the file someway like this:
<br />
long nFileSize;<br />
ifstream objStrmReader;<br />
<br />
objStrmReader.open("my file.txt");<br />
objStrmReader.seekg(0, ios::end);<br />
nFileSize = objStrmReader.tellg(); <br />
and it is working quite well. But then, my "boss" told me that the file I'm opening can be of -be prepared- 17 GB long! This because it can be an Oracle dump file, and it can be that huge! So I'm in trouble here, because ifstream::tellg() returns a long value, and I'd need to return me a double, so I can hold the value (because with long I get an overflow).
Does anyone can help me with this? Thanks a lot.

Use the Windows SDK functions to work with the files if you can.
SetFilePointer(...);
or
__int64 _filelengthi64(...);
Both of these function can do what you want.
Good Luck!

I am developing a user interface software using VC++ 6.0. I have a written document that tells a user how to use the software but I don't know how to link it with Help menu. Any help with it much appreciated.

I am trying to write code that takes data from an MS Acess Database, and moves it to software I purchased called Problem Tracker. I purchased their SDK, and they sent a dll file along with a list of functions on how to upload records. What I can't seem to figure out is how to use ODBC to access these records from my Access database and apply them to these functions. Any links you could throw at me or advice on where to start would be greatly appreciated.

Hi,
Is is it possible to check if SQL Server Agent is running and if it is not running start it to schedule tasks from MFC app in VC++.net
Any help is highly apprecited!
Thankx

SQL Server Agent run as Service in Window2000 and above
So u have to use service api' to achieve that.
here are API's
1->OpenScManager -->open Service Database of local system
2->OpenService -> Open the Particular service
//now check Status of Service
3->QueryServiceStatus
and to run service
4->StartService and to stop service ControlService
or you can look at this article

I got a little proglem here though
The computer which I am interested in is on LAN. that is the computer running SQL SERVER and where SQLSERVERAGENT service should be running.
the problem is
OpenSCManager function returns RPC server not available if I use the following call:
::OpenSCManager( "\\servername", SERVICES_ACTIVE_DATABASE, SC_MANAGER_ALL_ACCESS );
and it paase and returns a handle if I make this call
hscManager = ::OpenSCManager( "servername", SERVICES_ACTIVE_DATABASE, SC_MANAGER_ALL_ACCESS );
the subsequent call to ::OpenService passes if i do this
hscService = ::OpenService( hscManager, serviceName, SERVICE_ALL_ACCESS );
but then the call to QueryServiceStatus fails if i do the following
::QueryServiceStatus( hscService, lpServiceStatus )
the error code says Invalid Handle (i assume hscService ).
What am i doing wrong here?
If the calls to openscmanager and openservice paas the QueryServiceStatus fails. but if I append "\\" to the servername the openscmanager fails.
what is going on here??
Anyone can help?

Ok. I've tried putting in every valid path combination in the projects settings, but the .obj files ALWAYS ends up under $(ProjectDir)/Debug. No matter what I do. Any ideas?

I remember having problems with this a while ago.
Check that the 'Object File Name' (C/C++ - Output Files) is set to the location that you expect, if visual studio can't work out what the location means it will output to the default location (with no warnings or errors). Specifically check that you have a trailing slash.
$(IntDir)/
