Google Chrome & OpenClient Connection problem

19 May 2015 - 10:54 PM

Hi everyone,

 

We are deploying ProIV (V8) functions on Windows 7 tablets using OpenClient on Google Chrome. The tablets are connecting wirelessly. During the day some of our users are experiencing the "white screen of death". I.e. they will go to the tablet and touch say a field on the function and Chrome will go white. Sometimes they can refresh Chrome and get the session back but many times the refresh does nothing. To prove that it wasn't a disconnection we tried running Chrome via a Citrix connection to our server farm and today a user still got the "white screen of death". If the connection was down they would have got a Citrix error instead.

 

Are there any other users out there who are running OpenClient under the latest Chrome who are experiencing similar white screen issues?

Change Column Heading Of Listbox Fields

09 May 2015 - 07:49 PM

Hi there,

 

I'm trying to change the column heading of some listbox fields but nothing happens. ProIV help topic 510043 indicates I can but where it says I can use it doesn't make sense. I have a flat screen with a listbox field that links to a selection cycle. Does anyone know how to do this and where to place the logic?

 

Regards

Topic - 510043

It is important to note that the listbox.Columnheader is only valid in a paging cycle and is invalid in a flat screen, resulting in the following error message:

'ColumnHeader is an invalid Method or Property for Listbox Listboxname in the context of it's parent object type'

 

 


Build Maintenance Functions From Filedefs - Utility

21 December 2014 - 05:24 PM

Hi everyone,

I have been a ProIV developer for 29 years (I started when I was 2 :) ). About 20 years ago I started to get quite adept at mass changing/manipulating ProIV function code via the bootstrap source files. I can't tell you how many thousands of development hours I have saved my clients over the years. Like most of you seasoned developers out there I also used the old ASC utility that would auto create maintenance functions based on a file definition. Of course once I moved on to VIP/Developer it was no longer possible to use this utility. So 3 years ago I decided to write my own utility function to create maintenance functions from a file definition. I finished this utility a year later in my spare time and have been using it for 2 years now at my client’s site without any issues arising. Frank Coppola from Megasys has been using it in his Oracle environment for almost a year now with no issues. My utility is quite sophisticated in that it builds in some very powerful search capabilities. It also provides you with the ability to include non-key fields as search parameters. It builds for ProISAM, SQL Server and Oracle file definitions. Please see the enclosed help document for more details.

 

Now that this utility is proven and stable I am thinking of selling/licensing its use to other developers. I only want to do this though if there is enough interest out there to make it worth my while. Once I go down this path I have to be prepared to be able to handle my costs associated with its support. So the demand for this utility is going to help set its price. It currently runs on 6.1 to 7.1. I don't anticipate any problems with it running on the upcoming V8 but won't know until NGA release the bootstrap file definitions to me. By the way, I have already run this past NGA and they are OK with me selling this utility to the ProIV community so long as I provide you with the necessary disclaimers.

 

Who of you out there would be interested in purchasing this utility? You can either respond here or e-mail me at rossbevin@yahoo.ca. If you require a demo you can send me a vpx of a file definition and I will build and send you the maintenance function.

 

Regards
Ross


OpenClient & MS Office App Communication

02 December 2014 - 07:00 PM

Hi there,

 

We are currently an MFC Client shop but are looking at moving some users over to using OpenClient instead. Currently when we generate a Word, Excel or PDF document we do a client side call to open the Word, Excel or Adobe .exe and pass it the path of the file located on the server. I believe this is not possible when running under OpenClient because of browser security restrictions.

 

I would like to hear from other users to learn how they do the same thing as described above but in OpenClient. Is it possible or do you have to rely on the viewer only in the browser?

Positioning On A Field In A Paging Screen Automatically

21 August 2014 - 01:27 PM

Hi there,

 

I have a paging screen in change mode only. After the paging screen paints I want control to automatically position on a field in the first record. I want this done without me having to hit change mode or anything. I have investigated ObjectReference.StartInNavigation = value but am not sure if this will do what I want. The documentation doesn't tell me in what logic event to use it in. The same documentation also refers to .StartNavigationField but it doesn't appear to be a valid method.

 

If someone can tell me a way to do this I would appreciate it.

 

Regards

Ross
