Could it be that SHFileOperation is considered "interactive" and your service is not allowed to interact with the desktop?

Hello Jorgen
I already selected "interact with desktop" option from service control window.
but it's not working ..
Thanks for the help
Hari.

Have you also tried running the service as different users? I know the LSA (Local System Account) can be tricky. Especially if you're copying files to/from a non-local drive/shares. IIRC, the LSA account can only operate on local/physical devices.

I'm using vc++ 6.0,MFC and the CDao classes to open up access databases because of the better performance over ODBC. But when I try to open an Access 2000 db, it can't do it. I assume this is because the Jet engine it is using is 3.x. Is there a way to set which jet engine is used???
Thanks

Yes there is.
This is a known MFC bug. The workaround is discussed

Please note that Microsoft really are trying to kill off DAO. If you want to future proof your application I would reccommend switching to ADO (there are some C++ wrapper classes for this).
|

This is true.
Although, to be on rfraser's side, DAO *is* much more faster and efficient than ADO due to the fact thats its inherently closer to the native JET engine.
I have been using ADO, over DAO for a while now and know of its scalability. But the downside is that you lose the data access speed that DAO is so good at.
Switching to ADO, no matter what the speed depreciation, is the way forward. If I remember correctly, Microsoft has stopped support for the JET engine as of V2.7 of the ADO distribution files. This is to promote the MSDE engine; a localised, 'baby' version of the SQL Server database system.
My advice is to start out on your db adventure with the CDAO* classes then quickly move on to ADO for real world, scalable applications.

Hi.
I try to find a way to capture and manage starting of all application under windows NT serie (NT4.0, 2K, XP).
I would like manage a log file and save into it when user start some specific applications.
- The first way is by using a new gina.dll with fonction like WlxActivateUserShell (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/security/security/wlxactivateusershell.asp)
But this solution is so constraining to use it.
- Second way using a Hook procedure. I try to capture the WH_SHELL type. But the hook capture only event from the window which manage the hook.
I install two hooks : one for mouse event and one for Shell event for all threads (dwThreadId=0 when calling SetWindowsHookEx function)
With my application i capture all mouse events for every process and windows. But only shell events for my application, for the other windows it's appear no shell events capture.
If some one have some cool ideas. Thanx

You might want to look at various investigations of PsSetCreateProcessNotifyRoutine, including this [^] one.
The method of user mode notification is the crucial element in this and similar apps. Test under stress.

How does PsSetCreateProcessNotifyRoutine() sound?
Five birds are sitting on a fence.
Three of them decide to fly off.
How many are left?

Third way:
Change the default value of
HKEY_CLASSES_ROOT\exefile\shell\open\command
to
"c:\\pathtoyourfile.exe" %*
Your app gets called for every dblclk on ANY exe.
Then ShellExecute the original app (from command line).

Does anyone know if BLOBs can be inserted into an Oracle database, via a VC++ client, by creating and executing a SQL insert statement. I seem to recall reading somewhere that BLOBs can only be inserted via calling a stored procedure in the Oracle dB.
|
|
|
|
|
We used ADO to connect to our Oracle database. ADO can get/set BLOB data by using a SAFEARRAY attached to a variant. I can provide more detail if desired.

I would appreciate any detail you can provide. This is the first database task I've worked on. -Thanks!

First, we used the class found at http://www.codeproject.com/database/caaadoclass1.asp[^]
Then we did something like to add to the database:
<br />
CADODatabase db;<br />
CADORecordset rs;<br />
COleSafeArray sa;<br />
void *buf;<br />
_variant_t v;<br />
sa.CreateOneDim( VT_UI1, );<br />
sa.AccessData( &buf );<br />
<br />
sa.UnaccessData();<br />
v = sa.Detach();<br />
db.Open( "<some connection string>" );<br />
rs.Open( db.GetActiveConnection(), "select * from table", CADORecordset::openQuery );<br />
rs.Edit();<br />
rs.SetFieldValue( "blobfield", v );<br />
rs.Update();<br />
rs.Close();<br />
db.Close();<br />
The code to read is similar. Let me know if you need that also.

Hi all,
I'm doing a C++ programming on mobile agents...and I've been trying to find a way to get the CPU and memory usage using C++, so exatly like what we can get from Windows Task Manager.
I've looked into GetSystemInfo() and GetProcessMemoryInfo(), but there's not much useful information that I can get from them...
Can sombody help me? Thank you very much
Clara~

You might want to look at CreateToolhelp32Snapshot, Process32First and Process32Next.
<EDIT>Ooops - my bad - was thinking of the Processes tab... </EDIT>
|
|
|
|

GetPerformanceInfo found in PSApi.h is useful for getting memory usage information. For the processor load information, I've got no clue.
