In your ABL code, the input to the socket must contain a line break terminator '~n'. Otherwise nothing will be written onto the socket.

Just my 2 cents: You should protect your database against unauthorized access instead of freezing the schema. Freezing the schema does not distinguish - that means when your try to apply a legit schema update you will fail miserably unless you unfreeze the involved tables in the first place...

The point is that with a storage area of type I you don't have any control over what is stored in the blocks. To be precise, records from different tables can and will be stored in one database block. In a storage area of type II only records from one table a stored in a database block. Plus...

If you need the ROWID of a record for which you only know the RECID then you have basically 1 1/2 options: For understanding the difference between RECID and ROWID you may want to have a look @ Progress KB - FAQ: Recid and Rowid. You fetch the record with the RECID ( bufferName no-lock where...

The .NET Open Client uses a TCP network connection ( host and port ) to connect to the AppServer. From that point of view it is not relevant on which operating system the AppServer is running - given that the OS is supported by Progress of course. In almost all casese you may want to host your...

You get the RECID - which, in a nutshell, is the predecessor of ROWID. Although one is urged to use ROWID and forget RECID, it is still used in many places in the meta-schema, VSTs and other system tables. One of the disadvantages of RECID - amongst lots of others which are more relevant to not...

IMHO one always needs to balance between code transparancy and readability and not having to code lots of "boiler plate" code. Of course it is up to each developer to decide, but, I've been forced to wade through so much bad code that I am in favor of code transparency and readability. Using the...

There was a similar issue with OE10.2B and Windows 7. Maybe this is relevant for your socket errno=22.(781) Nevertheless, Progress 9.1E is more than 20 years old software which isn't supported on Windows 10. I doubt that it even was supported on Windows 7. I guess there is something in the...

There may be lot of others - but to me the RELEASE statement regardless of the case it is coded in belongs there too. I've not had one valid case to use it in some 25+ years.

So far I've never used the built-in OpenEdge.Net.HTTP client since it doesn't support the SSL client certificate which is required in the environment I work in. I did use the Microsoft .Net HTTP client on Windows and wget or curl on Solaris to do the job. I have several different scenarios where...

Forgot to add: The Google Chrome and M$ browsers like Edge and IE use the Windows certificate store ( Mozilla FireFox uses its own ). Via the MMC (Microsoft Management Console) you can also export root certificates from the Windows certificate store and import them into the Progress OpenEdge...

As fas as I know, the no host verify still needs the root certificate but it does not verify the host name in the ssl server certificate presented to the client. Without no host verify, when you visit for example www.amazon.com the host name in the ssl server certificat must match the domain...

Without providing detailed information on your requirements it is not possible to give a proper advice. There are many possible solultions if you want to create some form of audit. But which one is the one that suits you best depends. Using 4GL procedures has one big disadvantage which...

Just guessing - are you blocked by a firewall?

For one - in recent version of OE11 you should be fine with 8K block size on Windows too. There are old versions of OE10 and Progress V9 in which you could end up with a silently corrupted database. You still could end up with a corrupted database in more recent versions of OE11 but it won't go...

The first is the built-in WebService client for - as far as I know - SOAP based WebServices only. The latter is the one you need for REST based WebServices. But, I have to admit that I haven't used the first one in years and the latter one not all since the environment I am working requires the...

AFAIK, you only need to use the .NET HTTTPClient when the web service you are calling requires the client to present the SSL client certificate. If that is not the case then you should be fine with the HTTP client incorporated into the ABL.

Does that help? OpenEdge 11 Platform and Product Availability Guide (PAG) - Updated on January 10, 2017 - Documents - OpenEdge General - Progress Community

You need a PEM file - not PPK. Never had anything to do with PPK so I can't tell much about it. The PEM file must contain the private and public key and mine look like this: -----BEGIN CERTIFICATE----- ... -----END CERTIFICATE----- -----BEGIN RSA PRIVATE KEY----- Proc-Type: 4,ENCRYPTED...

For one I found out the hard way that a return error, especially when returned from the constructor or a property setter, is not always caught in the caller as I expected. Since I like my code to hold water I changed my habit and always undo and throw a new AppError instead. I think mixing an...
