Get WebApplication Administrator app name

Alberto Guti�rrez Arroyo — Thu, 11 Jun 2026 15:46:38 GMT

I would like to obtain the name under which a WebApplication Administrator app is running using DataFlex code.

Currently I have a temporary folder for files generated by the application (images, resources, documents, whatever that can be downloaded or uploaded by a user). I'm using a Windows Kernel function to obtain the default TempPath (%Temp%), then I add company name and product name (Get psProgram of ghoApplication). This works fine, each application and user has it's own temp folder and that temp folder is emptied after each server roundtrip.

However, I will need to deploy an application twice in the same server. So let's say my exe is "MyWebApp.exe" and the psProgram property contains "MyApp". This will create a temp folder in "%Temp%\MyCompany\MyApp\User26". Another instance of the same application (connected to another database) is going to use the same "%Temp%\MyCompany\MyApp\User26" temp path and that might cause problems (if two users with the same IDs are connected to each app, one might get his temp files deleted by the other instance).

Both apps will be created in WebApplication administrator as "EU1" and "EU2". So my temp folder will look like "%Temp%\MyCompany\MyApp\EU1\User26" and "%Temp%\MyCompany\MyApp\EU2\User26". To do that I need to get the WebApplication Administrator instance name, the question is:

TL;DR:
How can I retrieve this value using DataFlex code (see attached image)?

Application.css is getting igmored in 23.0

JeffKimmel — Wed, 10 Jun 2026 23:01:38 GMT

All,

I'm struggling with getting my custom themes to work on 23.0. I have the following in my application.css:

#OWEBAPP .RFIDlink button, #OWEBAPP .RFIDlink
{
color: var(--welcomeLineLink-color);
text-decoration: none !important;
background: none;
padding: 0px;
border-width: 0px;
}

In my source I have this in a cWebHtmlBox:

Set psHtml to "Welcome"

In Index.html I have (just to verify it's there):

However, the app does not respect these setting. Now if I move the css to the Theme.css it does work. This indicates to me that application.css is not being loaded and I'm not getting any errors in web tools so I'm kind of left hanging with nowhere to check. Just to verify, I removed the application.css and when I look into dev tools, I do indeed get an error when we try to load the non-existent application.css. Also, I have an exact duplicate workspace on my laptop & that does use application.css correctly. I'm again loss as to why application.css is getting ignored and any insight is greatly appreciated.

Thanks,

Jeff

cCustomWebView - New webview with close button

Giuseppe Catania — Tue, 09 Jun 2026 08:38:43 GMT

I didn't like the inability to close the webview.
Initially, I added a button to close the webview.
Later, with the help of AI, I created a new class based on the cWebView that displays the close button.
Now I'm happy to share the class and, perhaps, get suggestions for improving it.
Greetings to all

Code:

// cCustomWebView.pkg

Use cWebView.pkg

//Register_Object oMiaDashBoardWebView

Define dMiaDashBoardWebView for 0 // oMiaDashBoardWebView

Class cCustomWebView is a cWebView

    Procedure Construct_Object

        Forward Send Construct_Object

        { WebProperty=Client }

        { Category="Appearance" }

        { WebProperty=Client }

        Property Integer piDashBoardWebView 

        

        Set piDashBoardWebView to dMiaDashBoardWebView





        // Pubblicazione della procedura per consentire la chiamata tramite serverAction dal JS

    End_Procedure





    // Questa procedura intercetta il comando inviato dal browser al click della X

    Procedure procCloseWebView

        Boolean bShowClose

        WebGet pbShowClose to bShowClose

        

        // Se la visualizzazione della X � abilitata, inoltra la richiesta di chiusura standard della vista

        If (bShowClose) Begin

            Send procHideView 

        End

Clearing cWebComboForm

FrankValcarcel — Mon, 08 Jun 2026 22:06:30 GMT

The cWebComboForm seems to be non-refreshable. Once it is loaded the data sticks there is no way to clear the data and reload. So I am using UnLoadView after use to force reload. But if I need to refresh it in the view I am out of luck.

cWebBaseSelectionForm example?

DaveR — Sat, 06 Jun 2026 14:53:37 GMT

Anybody got an example of cWebBaseSelectionForm in action?

nvm, online help showed me more and it's not what I want

(What I wish for) ShowYesNo with parameters to pass

Mike Cooper — Sat, 06 Jun 2026 14:31:25 GMT

In the ShowYesNo

Code:

Send ShowYesNo (Self) (RefProc(ConfirmResponse)) "This is the first line of text.\n\rThis is the second line of text."

Wouldn't it be great if we could pass some parameters to the Procedure or Function that gets called (ie the "ConfirmResponse" in the example above

Constrain_file woes

Benjamin — Fri, 05 Jun 2026 18:26:30 GMT

Good evening,
I am experiencing issues with constrains within a 24.0 MobileWebApp and hope you could help me

I have a ZoomQuoteHdr view with following relationship: QuoteHdr --> Location --> Customer
On the view I have a customer and a location form field with the prompt button enabled and forward navigation set to the appropriate select view.

When I go to select the customer first, and then go to select the location, the SelectLocation view does not constrain the locations to show only the customer’s locations.

DD’s in ZoomQuoteHdr and SelectLocation are both like:

Code:

    Object oCUSTOMER_DD is a Customer_DataDictionary

    End_Object

 

    Object oLOCATION_DD is a Location_DataDictionary

        Set Constrain_file to CUSTOMER.File_number

        Set DDO_Server To oCUSTOMER_DD

    End_Object

 

    Object oQUOTEHDR_DD is a cQuotehdrDataDictionary

        Set DDO_Server To oLOCATION_DD

    End_Object

Appears to ignore the Constrain_file setting entirely.

Has anybody seen/experienced this and has a solution for it or can point me in the right direction?

Responsive application: Maximize modal dialog to available screen size

Alberto Guti�rrez Arroyo — Wed, 03 Jun 2026 11:43:14 GMT

Hello, I have been reported an issue with some modal dialogs. I have a web application that is using the Flat Desktop theme, that application uses web modal dialogs (lookups,...). When the application is being used in a high dpi laptop or a tablet, the dialogs might be too big or too small.

I would like to set the responsive properties so that web modal dialogs are "maximized" when the screen is smaller - in this case, once it reaches rmTablet size or lower. How can I set those properties? I would like to avoid using events like OnResizeWindow and other server events as that would increase the server load just for UI tasks.

Code:

WebSetResponsive piMinHeight rmTablet to 

WebSetResponsive piMinWidth rmTablet to

The help is very unhelpful 2

Ian Smith — Thu, 28 May 2026 13:32:25 GMT

The help needs a massive overhaul.

cWebTreeView :

I want to set the folder icon to the “open” icon if there are no child nodes. I think the “standard” icons are Font Icons so I will need to have and both a closed folder and an open folder icon – this is not a problem.

However, neither of these work!

Move "folder_empty.ico" to tItems[iIndex].sIcon
Move "images\folder_empty.ico" to tItems[iIndex].sIcon

Examples, examples, examples – the people who developed these controls know what is needed, it would be very helpful if they passed on examples to the people who create the help content!

HOW do I specify the icon file to used?

(Edit)
Also what size icons? Are Multi size icon files allowed? If so how is the size selected / set?

(Edit 2)
If I am using custom icons, how do I change the icon on a parent node from "closed" to "open" when it is expanded?

(Just more examples of why it is so difficult to move from Desktop to Web.)

cWebCombo

Quote:

Description
In checkbox controls (cWebCheckbox, cWebColumnCheckbox), it is called when the checkbox is clicked. In all other controls, it is called if the contents of the control have changed and the focus leaves the control.

Not true, the OnChange event IS FIRED when the selected item in a �standard i.e. cWebCombo� is changed.

Spent some time trying to find out what is fired when the selected item in a cWebCombo is changed before just trying the OnChange event in desperation!

cweblist context menu

FrankValcarcel — Tue, 26 May 2026 20:32:57 GMT

When I am in cweblist and do a long press (on a cheap tablet) I get a context menu with Download, Share (and an sms incon) and Print.
Where is this coming from, can we modify it?

How does the user change a column width on a tablet. We have users with different tablet types and no one setting works for all.
