That machine has three SQL instances. The first is the default installation and contains only the master database. The other two instances each hold only the ERP database, one for production and one for testing.

There is nothing else. My sensations say that there is something works bad in that machine. I asked for that.

FOR ALL WHO READ UNTIL HERE. There might be a misunderstanding. When I talk about "test," I do not refer to developer testing. Our supplier has its own developer and test environments. We, while developing the customization, have our own developer and test environments. We put the application (often, when required) in a fifth environment to permit third parties to test their development when an external connection is required. Finally, the sixth and seventh environments are the production and user testing environments (where customer employees can test and learn how to use new capabilities). These are the two environments present in the production machine, what I have called until now "production" and "test".

We have dozen of customers that has the same configuration. The customer that has the little DB space (some of them has over 150Gb of DB, one of them is over 200Gb, this one has 11 Gb) and uses less the server (it makes about 10 invoices at a day, some other customers has the same work per minute, it uses only few barnches of the applications on the DB, the others uses much more). All other customers works well in both test and production (that are in the same machine but in different sandboxes, and stress test on test machine doesn't impact in the production one). Why has this customer problems on test memory space if all the other that stress much more the memory and cpu usage haven't if the pressure memory detection works properly? What is that make you figure out that are so secure that memory pressure detection works properly? Do you saw some reports?

No. SQL Server IS DESIGNED to free memory up. From the link I posted (https://learn.microsoft.com/en-us/sql/relational-databases/memory-management-architecture-guide?view=sql-server-ver16#memory-pressure-detection):
"The Resource Monitor task monitors the state of external and internal memory indicators. [...] Memory brokers monitor the demand consumption of memory by each component and [..,] it calculates and optimal value of memory for each of these components. [...] This information is then broadcast to each of the components, which grow or shrink their usage as required."

I think the focus of the problem is not properly centered. Let me correct the question

Menci Lucio 22-Feb-24 9:25am View

Right observations, but not the right answer. It seems that Memory pressure detection[^] doesn't seems to work properly in that server. I don't know how to monitor it and change its behaviour.

Yes, of course, you are in right. After a lot of headaches caused by my wrong choice, I build my project from 0 using some command classes.
I'm a newbie about c++, I'm writing in C# and I was wondering if there is a way to make something like events. But C++ is not c#. Maybe C# events was made by command pattern...

Thank you

The point is not this one. The point is that I'd like to not define them in the base class... I think that if I don't find an elegant solution I will define all methods in the base class as not abstract ones.

Menci Lucio 17-Dec-19 3:44am View

Hi, thank you, but if I don't want to use virtual methods and override them there are some reasons. I have a lot of subclasses of the BaseClass in my production project, for example, there are led lights (the virtual methods has to be switchOn, switchOff, switchState, startTimer, blink, blinkFast), serialQueue (sendLocalMessage, sendGlobal, sendARequest), display (showState, switchOff, showError), and many others. I tried to define all virtual methods in the base class, but all of them has to be defined into derived ones (see the code I posted).

The last but not least reason is I'd like to know if there is a way to do that, for personal knowledge, and for pride :-)

Menci Lucio 16-Dec-19 12:33pm View

This is what I had trying to do, but I was not able to use the function pointer defined in the base class to define a function in the derived class:
the line

fx add = &Derived::_add;

returned the error

error: cannot convert 'int (Derived::*)()' to 'BaseData::fx {aka int (BaseData::*)()}' in initialization

This was the result of my headache :-)

Found! (maremmamaiala) The content of the file didn't reflect the extension. I don't remember what I did into the old PC. I opened the file running as not administrator, SaveAs specifyng the file type, now Excel right opens the file.

Menci Lucio 29-Oct-18 12:47pm View

«What parts of your code require admin permissions?» A call to an exe application that uses a ODBC/DB2 connection. «Where is the file copied to that you're trying to load it from?» Into the same directory that Application.StartUp says. In particular %UserProfile%\AppData\Roaming\Microsoft\Excel\XLSTART, that is the same in source machine and in destination machine. «Any error messages?» No errors. just Excel doesn't read the Personal.xls if it doesn't run in administration mode.

I updated my code.

DocumentList can contain the key and can not. If it contains the key, its value can be null and can be not null.

There are four checks. If there is a key (first check true) and its value is null (second check false) returns, if its value is not null, third check is false.

If there is not a key (first check false), the third check is true, newDocument could create or not the document, put the result into the documentList, and the fourth check could be true or false (if the document is created or not).

No checks may have only true or false result.

documentList is a Map (a TreeMap exactly). I think that the compiler doesn't know that a null value could be passed to the put method.

Menci Lucio 9-Aug-17 6:16am View

I cleared a little bit my code to see only the interesting rows for the purpouse, but the original code, instead:
TransferDocument dtr = (TransferDocument) documentList.get(getCurrentKey(fileRow));
was:
String currKey = getCurrentKey(fileRow);
TransferDocument dtr = null;
if (documentList.containsKey(currKey)) {
dtr = (TransferDocument) documentList.get(currentKey);
if (dtr == null) // already found into the search, already done
return true;
}

In this way, the Already done warning will appair once only.

The VB class is so big that I did not see the intellisense suggestion...
Thank you

TestProperty has not arguments. See the

Public Property Message(useSQLInfo As Boolean?, manageRN As Boolean?) As String

in my source into the first post

Menci Lucio 25-Jul-17 6:42am View

This is my start point. My problem is that I had to use reflection in C# uniquely to raise property getter/setter with arguments written in VB

Menci Lucio 25-Jul-17 6:40am View

They are two different projects that create different dll/exe in the same solution (for debugging). I was able to call all methods and other properties of Manager inside the C# project.

How did you install it? Where I can find it? I wasn't able...
I installed the CRRuntime_12_3 a lot of time ago, and I found the CristalDecision.CrystalReports.Engine.dll in C:\Program Files (x86)\Business Objects\Common\4.0\managed.
Now I just installed the CRforVS_redist_install_64bit_13_0_17 (downloaded from http://scn.sap.com/docs/DOC-7824), disinstalled ed installed the CRRuntime_64bit_13_0_12 from http://downloads.i-theses.com/index.php?option=com_downloads&Itemid=481&task=downloads&groupid=9&id=101), but in booth situations I wasn't able to find the CristalDecision.CrystalReports.Engine.dll in my disk but the v12.0 I already had.

@kjammy Because I had not a report file. I put if(false), created the XML, created the Report, replaced the if(false) with if(true)

Menci Lucio 30-Jun-16 4:14am View

FOUND!!!! Damn'it!!!! Some strange update (I think Skype) drop the IBM\SQLLIB\BIN path from the path environment variable!!!! I still having some problems with Crystal report, but MAYBE the cause that Crystal report doesn't run are differents. Now the Legacy type 2 run wells.

My machine is for a battle use, I know that it was better if there would be a server for db, but I have to use it in this way...

Menci Lucio 27-Jun-16 12:53pm View

Hi,
It's possible that Crystal Report 8 crashes when I try to connect to DB2 for the same reason?
Maybe (I'm not sure about it) that when the Legacy Type 2 driver stopped to connect to my db2 engine, Crystal report 8 stopped to connect too.

I'm not sure because I use a newer Crystal Report, but I have a customer that needs to use the old one and I have to edit an its report...

How can I re-estabilish the prior conditions?

Menci Lucio 17-Nov-15 10:22am View

I'll say it for you, stop with polemics, you're getting ridiculous

Menci Lucio 17-Nov-15 3:32am View

Hey, I haven't the question of answers I make, elsewhere I wan't make question. It's no a good policy reply "Best remove this post to avoid down-voted" or "You need to grasp the foundamental" or "is a lack of understanding" or "have no meaning here, go to documentation" or something else. I ask for an help in a forum, not wanting to recite a ritual sabbatical. I made only an example, and not put 23k classes to see all of the project.
In .net area of this forum people try to help who needs an help. Evidently in java help people is prohibited. Sorry! Next time someone ask me if is better java or .Net, I reply that .Net forums are serious. Before now I always said that they are two similar and different worlds without needs of preferences. You make me thinking seriously about to leave from codeproject. Are you that deserves a downvote, but I respect everybody and won't do it. Sorry, I'm not like you.

Menci Lucio 16-Nov-15 12:48pm View

Yes, of course, the program won't compile, but not for first your reason. I called the class Main, and the public Main() is its constructor. The entry point should be called main and not Main.
The program won't compile because I forgot the return inside the inits methods.
I already had that functions and they are the n-th element of a very long chain of hierarchy, and they have a lot of imports and they are so long. I wrote only a summary.
