Since the following snipped of code works fine on my system:
CFile file;
MyObject obj;
file.Open("foo.txt",CFile::modeWrite|CFile::modeCreate);
CArchive ar(&file, CArchive::store);
obj.Serialize(ar);
ar.Close();
file.Close();
hope that helps.

Yes. I was wrong.
It was not this fp.Close() which was causing the exception.
It was another Close().
Anyhow learned a few new things.
Thank you all.

You can set your service, depenendent on other service, that you feel need to run, for your service to start succesfully.
I dont know about database services, but you can identify by looking services explorer.
Once, set your service depend on other service, It will wait to start that service and then initiates its start process.

Just a thought, is your service running under Local Account?
In that case, you won't be able to connect over the network (since noone has logged on). And you wan't be able to connect to the DB (over the network).
Could this be the cause of your problem?

Hi,
It shouldn't be the case, because Local account is not the one which is used to log in to the database.
I'm not quite certain, but MSDTC is probably what you're looking for. If you add it as dependency for your service, it should be working properly.

Hi friends,
when i will debugg my project breakpoints are not setting properly.After debug i will get white color mark instead of red color.
Error message:One or more breakpoints cannot be set and have ben disabled.Program stop the execution of program.
These following setting i have done for debugger.
1)Project->setting->debug->server exe file path.
2)Project-> setting->c/c++->optimization->Disabled(debug)
3).........................-> debug info->Program database for edit and continue
After buliding i am not getting pojectname.pdb. but i am getting Old project .pdb file.I guess problem with .pdb file.I hope anybady having some idea.please share your ideas.

Generally, this happens, if no debug symbol loaded for code, you have set breakpoint for.
|
|
|
|
|
I have set breakpoint for one function called DocOpenOldStyle().But it doesn't matter for function.
May i know what type of setting i want to do?
|
|
|
|

What type of application, you are working with?
Make sure following things,
-You are using Debug configuration.
-If you are developing dll/COM add-in, its loaded in target exe correctly.

Hi Prasad,
Thanks for ur suggestions.
I am using Win32 appliaction, and Debug configuration.
I have loaded target exe file properly.I am sure about this things.
Inspite of these setting i am getting same error.
We are implementing new project in that Debugger is not working, but in another system Debugger is running properly. I do not understand what is the probelm?

Try a "Rebuild all"

"Rebuild all " dosent work.I have done it earlier.would please give other suggestions.

See the answer from prasad_som. Says it all.
I can think of two resons for not reaching the breakpoint:
1.
The code in question is commented out, or defined out.
2.
You are not doing a debug build.
If I'm wrong, (and a "Rebuild All" doesn't help), then I'm out of guesses.

Hi,
Thanks for your suggestions.
I got your second point.But i am sure that i am using Debug version of build.I clarify from
Build-> Setactive configuration option from my code.
But i didn't understand your First point clearly.Please explain briefly.

OK.
Assume you did wrote some code, i.e. a function.
Then you put a breakpoint in that function.
Later on you rewrote the entire function, but you didn't want to remove the first version of it.
So you commented out (or defined out) the function (with the breakpoint still there).
Now, the breakpoint cannot be reached, so VC++ will warn you and disable the breakpoint.
An example:
void class::func()
{
m_classvar = 0; // You out a breakpoint here
}
Now, you rewrite the function (and comment out the old version of it), like this (or with /* ... */):
(notdef is not defined)
#ifdef notdef
void class::func()
{
m_classvar = 0; // You out a breakpoint here
}
#else
// The rewritten function.
void class::func()
{
m_classvar = 4;
}
#endif
So, your breakpoint is set on a piece of code that will never be compiled, and hence, it will be disabled when you start your debugging session.

Thanks for giving Example.But i havn't done like this in my code.
Kakan it is very stange that we are running our older projcet with debugging option( Debugger working properly).
but its doesn't work for my new projcet.

|
|
|

I'm out of ideas here.
But I suppose you can do what I do when it happens to me:
Go to the line where your (disabled) breakpoint is. Press F9 twice.
That should remove your old breakpoint and insert a new one, hopefully enabled.

Hi,
I am the administrator of my system.My system is in network.I don't know Why
a read-only property is set to my project Folder.I have Visual Studio workspace in that folder . I have created VC++ project .Now, When I try to add new Functions using the right click properties of a userdefined dialog I am getting an error saying that "Add/Remove Operation is Impossible because the codeelement CMYdialog is ReadOnly" .When googled some articles say that its a VS2005 bug.
Is there any way where I can remove the ReadOnly Property?
Any Suggestions would be helpful.

You may have accidentally set read-only property.

If so, you can check if its fixed, or any work around.
