Can local transport be used between two applications or only in a single application?

Kind regards,

We noticed that when the kbmMWGlobal is included in the uses of a DLL the application that uses the DLL will hang when it tries to unload it.

DLL Code:
library DllWithKbmMw;

begin
end.

Exe Code:
unit Main;

Unloading DllWithKbmMw.dll is…[Read more]

Looks like the line 3222 in kbmMWSecurity contains a bug which results that DoOnLogin is never called.
if (ctx.Actor<>nil) and (not ctx.Actor.Internal) then
Should be:
if (ctx.Actor=nil) and (not ctx.Actor.Internal) then

Kind regards!

It looks like there is a bug in kbmMWGlobal’s kbmMWGetFileVersionInfo function.

Current code 5.23.00:
ADebug:=(FI.dwFileFlags and VS_FF_PRERELEASE)=VS_FF_DEBUG;
ASpecialBuild:=(FI.dwFileFlags and VS_FF_PRERELEASE)=VS_FF_SPECIALBUILD;

When I try to reach the C4D Shop http://www.components4developers.com/shop.html I get an internal server error 500.

It looks like this one is reintroduced in version 5.21 (and still there in 5.22)

In my application I have the following code:

Requirement := TPMRequirement.Create;
try

Requirement.PMItem := Orm.FromDataset<TPMItem>(FItemTable, True, True);
Requirement.RequirementItem := Orm.FromDataset<TPMRequirementItem>(FDetailTable, True, True);

Because the constructor of the TPMRequirement instanciates both PMItem and…[Read more]

When I do an ORM.Update I get a dynamic SQL error. In Devart’s DBMonitor tool I see that for some reason the table name in the where clause is quoted 3 times instead of 1:

UPDATE “Person” SET “FirstName” = :FirstName,”LastName” = :LastName,”Notes” = :Notes WHERE “””Person”””.”PersonID” = :KBMMW_KEY_PersonID

The strange thing is that when I…[Read more]

I noticed that the TkbmMWDatastoreSequencer.GetValue always make the sequence name an uppercase . I think it would be better if this was a setting(perhaps in the MetaData component).

reshlp.HTTPStatusCode:=reshlp.HTTPStatusCodeFromServerStatusCode(res.StatusCode);

I want to control the what http status code is returned to the client. I know you can do this with

kbmMWRaiseHTTPError(407,’….’)

or

raise EkbmMWHTTPException.Create(407,’…’)

But it seems a bit odd to use an error if it isn’t for instance if you want to return a 201 Create status code.

I have to set the status code like this, but it…[Read more]

What kind of path type is used in the example below? Does it have a name?

i18n.Save(”, ‘json’, ‘file:..\..\Translations.json’);

Thanks in advance!

I am writing a small application that reads translations from a database and converts it to a i18n yaml file, this works fine except that I didn’t figure out a way to set the TkbmMWI18NLanguage name property since it’s read only. For now I have just modified the TkbmMWI18N source and added a write to the name property and this works fine. I a…[Read more]

I wondered if it’s possible to use a phrase as a value for a property:

phrases :
“sCancel”: “Some cancel button”

properties :
Form1.btnCancel.Caption: sCancel
Form1.btnCancel2.Caption:sCancel

Thanks in advance!

I have tried to enable learning properties the following way:
i18n.LearnProperties := True;
i18n.Load(”, ‘test.yaml’);
But for some reason the properties are not written to file. I have also switched the order of the lines above but that didn’t do the trick. I also toggled between saving and merging but this didn’t solve it either. If…[Read more]

Some things you might want to check:

1) Do you have a MetaData component attached to the kbmMWMySQLRewriter?
2) Do you have a kbmMWMySQLRewriter attached to the kbmMWFiredacConnectionPool?
3) Does the table name in your entity match the table name in MySQL [kbmMW_Table(‘name:person’)]
4) Make sure that the meta data component…[Read more]

If I remember it well there where some serious issues in XE5 with generics which are heavily used in the ORM framework. I think you need XE7 or up.

Is it posible to declare a rest method as a default/catch all? Something like this:

[kbmMW_Rest(‘method:get, path:*’)] // Will be called if the path doesn’t match any path defined in the service.

Thanks in advance!

In the blog article “REST easy with kbmMW #15 – Handling HTTP POST” you describe in example 2 howto obtain url parameters.

For my OData/Rest server I need to use $ character in the path attribute, but this doesn’t seem to work (service not available). I noticed that the path matching is done with regex and since the $ char has a specific meaning something might go wrong… Could you look into this?

Thanks in advance!

I implementing a REST client for an existing REST API which I don’t control. The thing is that the JSON for the REST API uses unnecessary elements for instance:

{  “FiEntryPar”: {    “Element”: {      “Fields”: {        “Year”: 2025      }    }  }}

My Delphi Objects follow the same structure and that is a bit confusing in my opinion. I…[Read more]

Is there an easy way to just use the current record in the FromDataSet method?

Thanks in advance!

I am currently evaluating kbmmw for my employer so I use the trial/CE version. Is it correct that the ToDataSet method doesn’t work in the trial/CE version?(would make sense to disable it)

Kind regards,

Luigi

How can I use nested dataset with the memtable? I have created to kbbMemTables “main” and “nested. The main table has a field of type dataset, but I don’t know how to glue the two together? A default TClientDataset has a dataset field property, but I don’t see a kbm equivalent ?

I have recently added a kbmmw fileservice to my existing server application which contains mainly query services and smart services. I noticed that when I am uploading a large file to the server that the response for a query service is much slower in this case.

It works 🙂 Just tested it with a 64GB file up and down.

It is true that I did not anticipate sending huge files (>2GB) back in the days.

I don’t blame you.

As far as I know there is no specific documentation on the rewriter. The rewriter is needed when you use the ORM. It rewrites the SQL to match your target database requirements. It compiles on Win64 here without a problem (I am using enterprise) What version do you use? And what error do you get?

I’ve created a fileserver+client with kbmmw and uploading works fine except with large files (the file I tried was  a +5GB zip ). I don’t get any exception it’s just that the file transfer seems to stop after 1.009.617 kb this number is the same every time.
