Hllapi Dll Download For Qtp Performance
Kirby Apodaca
I am using Rumba Unix 9.4.1 on Windows 7 Pro Enterprise in conjunction with a process automation tool that sends keystrokes and scrapes the Rumba screen as well per the automation script I developed. I would like to know how this is being done. I thought it was HLLAPI but now I have to wonder if it might be DDE? First, I launch an emulator with a shortname of "X". Then I launch the automation tool but don't start the script. I use "listdlls" at this point and there is no HLLAPI DLL listed being used by the tool. I then start the script and after "Detect Emulators", listdlls shows "ehlapi32.dll" is now being used by the automation tool. I then step the script to where keystrokes are sent to Rumba (and displayed) at which point I use ListDlls to see what Rumpage.exe is using and to my chagrin no HLLAPI dlls are found. Any idea how Rumba is communicating?
3. Set the eHLLAPI shotrname in the line Astr="X"
4. Execute the macro, wait for the message box to appear. Assuming you get a successful connection, do not close the message box.
i.e. the macro is still running, as is connected to the Rumba session.
5. Using your automation tool attempt to connect to the same Rumba shortname. It should fail with a Return code of 11, if the automation tool is indeed using the eHLLAPI interface.
6. Once you have finished, return to the Message box and dismiss it.
A dumpbin.exe /exports on the ehlapi32.dll indicates that there is no DllRegisterServer method in the library, which would explain why you can't RegSvr32 it. So it look like a wrapper dll would be one solution.
The Rumba ehllapi implementation is not a standard ehllapi implementation in that it includes dozens of WD_???? functions, which if you were writing your own application might be quite useful, however given that you are using an off the shelf automation tool, these WD_????? functions are more of less redundant in your scenario.
Naturally, I'm assuming that the automation tool will handle everything by way of return codes and parsing off the various parameters after the function call. Just as it would if you didn't have to create a wrapper .dll
IBM i Access for Windows is out of support effective from April 30, 2019. It will not be refreshed for IBM i release 7.2 or beyond. IBM does not plan to support IBM i Access for Windows on operating systems beyond Windows 8.1.
For specific cases where the business-critical operations/applications are written in Excel/VB/C++ based programming language using IBM i Access for Windows, the answer is to migrate to IBM Personal Communication (PCOMM) which has a vast presence in IBM i and Mainframe arena. PCOMM shares the same features, interface, look-n-feel, and Automation APIs (32 & 64-bit) for EHLLAPI, HACL libraries (native and Java) supported in various programming languages.
IBM Personal Communications (PCOMM) brings the power of personal networking to your workstation by exploiting networking capabilities to provide a variety of connectivity options supporting local area network (LAN) and wide area network (WAN) environments. Whether it is for host terminal emulation, client/server applications, or connectivity, Personal Communications offers a robust set of communication, networking, and administrative features.
Starting from version 14.0, the 64-bit version of PCOMM will be supported so that PCOMM can run as a native 64-bit application on all supported 64-bit Windows OS. Switching to 64-bit offers various performance advantages, as well as better interoperability/integration with other applications as more and more applications, are being ported to 64-bit.
Automation APIs that were previously supported for 32-bit applications (e.g., MS office 32-bit) will now work seamlessly on 64-bit applications to support the same functions in 64-bit PCOMM. For example, a 32-bit automation application written for 32-bit IBM PCOMM will now work seamlessly with very minor changes with PCOMM 64-bit on MS Office 64-bit. The same is true for IBM i Access-Windows, however, minor code changes may be required for the IBM i Access-Windows applications to work on PCOMM 64-bit.
PCOMM 64-Bit is built using the latest VS2017 compiler, thus providing an advantage of compiler optimization improving the runtime performance. Refer to Microsoft Blog citing an increase in runtime speed with VS 2017.
a. The look and feel of these Emulators are almost the same.
b. Underlying communication protocol with the Host is the same.
c. Both use the same IBM Standard EHLLAPI/PCSPAI/HLLAPI API binaries to communicate and manage host 3270/5250/VT sessions.
d. Colour mapping, keyboard, workstation, macro files, etc shares the same extension and format.
e. PCOMM supports HACL automation libraries which are supported in many programming languages for 5350/3270 sessions.
Note: To migrate to IBM PCOMM, please contact your IBM sales contact/representative/Business Partner with your requirements and they will provide you more information on procuring IBM PCOMM licenses.
The virtual control panel allows you to view information about your system which is accessible only from the control panel. The information which can be viewed using VCP includes:
Machine type, model, serial number, and partition number.
Initial Program Load (IPL) mode: Normal, Manual.
IPL type: A, B, C, D.
System Reference Codes (SRCs) for the current IPL.
State of the VCP connection to the system.
The console support is only available with the ACS based support.
Ultimately the choice of continuing IBM i Access-Windows or upgrading to ACS or IBM PCOMM boils down to what features an organization wants to continue with. If your organization works on 32-bit applications, then IBM i Access-Windows will suffice the need. ACS brings in 5250 printers and emulation and Session Manager support, as well as other functions. However, one needs to decide about the Automation Applications which were written for a 32-bit platform. With IBM PCOMM, will be able to leverage the features which Windows 10 brings for 64-bit applications and the fact that 64-bit Automation Applications will work seamlessly. If you are using these emulation-based solutions majorly for building Automation Applications that are written in Excel/VB/C++, then IBM PCOMM is the solution.

Traditional green screens are complex for new users. There is a growing demand for a more modern interface. VSR has enabled us to avoid a complete and costly overhaul of the system, while leveraging the usability and performance of our current technology. In just 3 months, we were able to improve the user experience by transforming the aesthetics of over 1,200 screens and integrating key functionality such as SSO.
I would like to use the 7z DLL to append small amounts of data to one compressed file. At the moment my best guess would be uncompress the 7z file, append the data, and recompress it. Obviously, this is not a good solution performance wise, if the size of the 7z file becomes large (say 1 gb) and I want do save a new chunk every second. How could I do this in a better way?
The ctypes stuff has all the C-type data types (int, char, short, void*, ...) and can pass by value or reference. It can also return specific data types although my example doesn't do that (the HLL API returns values by modifying a variable passed by reference).
Believe it or not, mainframes are still the systems of choice for companies that need high-transaction throughput with guaranteed reliability and consistent data. Insurance companies, banks, and the retail, and transportation industries, for example.
According to Rosalind, a distinguished engineer at IBM, mainframes run all modern languages (Java, Swift, Node, etc.). Whatever you need to write your application; you can write it in that environment and then run it on the system.
I used to work for a large healthcare company that still used a mainframe application behind the scenes. Even though they had a browser-based application version, most customers refused to upgrade and use the new application because they were so proficient with data entry using the green screen application.
