Problem: Are there any further documentations on how to use INCLUDE or OMIT control statements in MFSORT? Resolution: Here is the description of the INCLUDE/OMIT control statements in the Net Express Help: ----------------------------------------- INCLUDE/OMIT Specifies conditions in which records will be included or omitted from the sort process. For details, see the IBM documentation to be found at Using DFSORT Program Control Statements. INCLUDE and OMIT are mutually exclusive. ----------------------------------------- You will note there is a link (http://www.microfocus.com/docs/links.asp?nx=dfs2) for details on how to use them. If you click on the link, it will take you to the documentations on DFSORT Program control statements. You will find from that site all the details about how to use INCLUDE/OMIT control statements.

Problem: How can access the Vtable from a COM DLL? The VTable is the low level interface  that a COM Object Object exposes. Its structure is similiar to a C Object. Resolution: If you already have a COBOL OLE Domain object you could use the COM Class library IUnknown "fromDomainObject" class method and QueryInterface to get the COM Interface (vtable) you want. Alternatively you could CoCreateInstance and QueryInterface COM API calls. If possible its far better to use a automation object so you can invoke on it. Thats far more forgiving and simpler from COBOL. Old KB# 5727

Problem: You may see this error message reported when using Net Express Application Server when attempting to execute a deployed application. The problem is that error gives in some customers and in others no. The environment is the same for all customers.      Could you help us to solve this problem, please? Regards, Resolution: The most common reason you would see this message is because you are attempting to run an application that has been built using the Net Express 4.0 runtime on a machine that only has the Net Express 3.1 run time installed. Because the Net Express 4.0 runtime cannot be found on the machine the error is produced. So the solution would be to either install the Net Express 4.0 runtime onto the client machine(s) or if possible to rebuild the application in Net Express 3.1 which will then use the Net Express 3.1 runtime available on the machine.

Problem: You may have a character based screen application that you want to run inder Windows as a full screen display. However, when you run it the screen display may be much smaller than required and you may want to extend the screen to be a full screen making the screen a 25 lines by 80 column screen. Resolution: COBOL doesn't set a 25x80 screen as default for console based applications. Instead, the screen characteristics are set by Windows. When you originally developed your app, 25x80 was probably the standard screen size, although there were some exceptions where 43 and 50 line screens were used. (These subsequently led to the intorduction of the C4 and C5 runtime switches). The only way to get a full screen is by clicking the top left corner of the application screen and selecting 'Properties'. One of the options then available is 'Full Screen'. However this only expands the display to cover the full screen and does not necess

Problem: How can I send to a printer connected to a USB port using the standard ASSIGN TO clause in the SELECT statement? Resolution: The way to print via a USB-port and not to LPT1/2 etc is to use the printer_redirection run-time tuneable. The printer_redirection tuneable causes ASSIGN TO PRINTER statements to go to the print spooler rather than LPTn. Therefore, provided the printer attached to the USB has been installed properly there should be no problem printing to it. There is no way to access ports directly in our product because the operating system APIs used for file handling do not handle USB port names. To set the printer_redirection runtime tuneable you need to create a runtime configuration file and then set the run time tuneable in this file. The default filename is 'cobopt.cfg' and this is just a standard text file. However, the file can be any name of your choosing (eg; myconfig.cfg). Then, to have the runtime system access the fil

Problem: Can I improve my SQL Server performance from COBOL via ODBC? This relates specifcally to SQL Server cursor performamce. Resolution: Using ODBC to SQL Server there is a lot of scope for tuning your performance. MS SQL Server's performance can vary greatly depending on what cursor type is being used. By default all cursors are Server Side cursors. This can be inefficient for example when reading through large sets of data. Setting concurrency to READONLY and making it FORWARD only should those type of cursors go much faster. Where you need server side cursors you could try the SQL(PREFETCH=n) directive. This will get individual rows in blocks rather than in a single row. This can speed up performance. Some work has taken place to help with people migrating from mainframes. There is a new compiler directive SQL(BEHAVIOR=....). This allow you to specify what behaviors you want and it then does some optimisations to cursor types. Some ex

Problem: Found cblcore modules  in many directories.  Can these safely be deleted? Resolution: Cblcore is a debugging tool - it puts out a cblcore dump anytime an abend occurs. By typing in CBLCORED from a command prompt, it will put up a pop up box and you can enable or disable it. If you have already resolved the abends and do have no need to look at the dumps, you can delete them. If this is occurring on your development machine, check the animate options and uncheck core dump to stop using the function. Old KB# 5752

Problem: Only 16 colours are displayed when using the colour option.  The computer is set to unlimited number of colours. Resolution: The Form Designer Script Assistant helps you set up event handlers that: Invoke methods Get and set properties Get and set styles The Script Assistant has five tabs: The Events tab The Methods tab The Properties tab The Styles tab The Scripts tab The Events, Methods, Properties and Styles tabs provide you with a point and click method of creating event handlers, while the Scripts tab enables you to enter and edit your code directly. The contents of the tabs and the behavior of the Script Assistant vary depending on whether you are working with HTML controls or ActiveX controls. Styles contain information about the appearance of an element. Just as with properties, you can set a style to change an element s appearance, or get a style to discover its appearance.  For example, most ActiveX

Problem: Program A call Program B, receing error on call to Program B. Works in debug mode, error produced in Release Mode. Resolution: This was corrected by a HOTFIX for  RPI 1057346 - this occurs due to a change to the compiler to accommodate mainframe dialects. the outdd and\\or  indd are the cause and the solutions is as below: Run-time system error COBRT226 ("EXTERNAL data definition        inconsistent") was returned sometimes if programs in a run unit had been compiled with a        mainframe dialect. The error occurs because the        attributes used for the SYSOUT file when using a mainframe dialect        changed in WrapPack V4.0.005.        If you receive this error you should recompile all the programs   &nbsp

Problem: Method to open a large data file with Net Express to view the contents. Resolution: Have the following section setup in the extfh.cfg file: [XFH-DEFAULT] FILEMAXSIZE=8 Where the FILEMAXSIZE parameter specifies the number of bytes used internally to store file offsets. This also affects internal locking mechanisms: programs sharing the same file all need to use the same FILEMAXSIZE settings to ensure semaphores and record locks are handled correctly, thereby avoiding potential file corruption in shared files. FILEMAXSIZE={4|8} Default: 4 4 Limits file addressibility to 32 bit values which is compatible with earlier versions of Micro Focus products. 8    Allows up to 64 bit values for file addressing on Windows NT platforms when accessing the NTFS file system, but changes the underlying record locking mechanism. Therefore, if you are sharing very large files, that is files greater than 1Gb in size, all programs

Problem: Release 4.0: When compiling a program with a single syntax bug, this causes an aftereffect of about 1500 error messages. It may end with an "Unexpected Error while syntax checking", or a hanging IDE, or it may take several minutes until the IDE can be used again. Killing the IDE using taskmanager does only help if the IDY-file is deleted also. Resolution: A better solution is offered by the compiler directive MAX-ERROR. Limiting the number of errors, e.g. to: MAX-ERROR"50 E" MAX-ERROR"40 S" e.g. placed in the COBOL.DIR file, will improve the situation. After reaching the specified number of messages, the compilation will be aborted by a (last) "Too many errors" message. Old KB# 5778

Problem: Does Application Server support Windows Clustered environments? Resolution: Micro Focus Application Server has no direct support for Clustered Services. Applications written in COBOL however should run on a Windows Server machine that participates in a Windows Cluster. However the application will not be cluster aware. There is a API that applications can use to make themselves cluster aware:- http://msdn.microsoft.com/library/default.asp?url=/library/en-us/mscs/mscs/windows_clustering.asp?frame=true If you need to make your application cluster aware then you will need to to use these apis.
