WebApp in an iframe gets browser compatibility message in IE10

matthewd — Wed, 19 Jun 2013 23:52:26 GMT

I included a web app in a plain HTML page using the following code:

Code:

Chrome and FireFox also bring it up just fine in the iframe. In IE10, I get an "Unfortunately the browser you are using is not supported by this framework. Please upgrade to a more modern browser..." message.

If I bring up the WebApp in IE10 using the URL, it works just fine. There just seems to be a problem reporting the browser version when the WebApp is inside another page's iframe. Should this work?

Invalid oLogoutMenuItem Caption

craigkrum — Wed, 19 Jun 2013 20:29:07 GMT

I just downloaded and installed Beta 6, and added a web project to an otherwise empty workspace. I did a compile, and was told that the following psCaption line contained an unresolved forward reference:

Code:

                                    

Object oLogoutMenuItem is a cWebMenuItem

     Set psCaption to C_$Log

I think it was supposed to be C_$LogOut, which does compile correctly.

Wrong max. number of characters for field names in documentation

Allan Kim Eriksen — Wed, 19 Jun 2013 19:38:30 GMT

The documentation still has the 15 character limit in the DF_FIELD_NAME page.

Quote:

In the Embedded Database, column names can be any combination of characters, up to 15 characters long, that starts with a letter and contains no punctuation other than underscore (_).

That should be 32.

Kudos to the team - beta 6

chuckatkinson — Wed, 19 Jun 2013 19:03:09 GMT

Dang ! (that's Texan for holy cow!) -- beta 6 speed is impressive ! I think it is noticably faster than previous betas. But maybe that's just me?

One little suggestion is to the change the default tpl's for the web objects to add a blank line that would be convienent to drag & drop into.

Example

Code:

    Object oMainPanel is a cWebPanel

        Set piColumnCount to 10

    End_Object

Add a blank line above the End_Object.

I can't seem to drag anything into these without the piColumnCount moving to the bottom (and I like it at the top).

Beta6 WebCombo behavior changed

philby — Wed, 19 Jun 2013 01:40:39 GMT

In a cWebCombo I had working fine under all previous releases, it has now changed after installing Beta6.

The list is filled via Procedure OnFill, and examination of the data via the debugger show the elements have all been set up correctly. But when the comboform displays, the first "row" of the combodata used to display in the form. Now it is blank. When I drop down the list, all rows are present and correct.

cWebModalDialog and OnCloseModalDialog

chuckatkinson — Tue, 18 Jun 2013 21:10:38 GMT

OnCloseModalDialog being sent back to the calling object before a Save Confirmation and the save actually happens in a popup modal dialog? So if the user saves some data in the popup - how would the view be informed and refreshed with the changed data ?

Code:

            Procedure OnCloseModalDialog Handle hoModalDialog

                Send RefreshListFromDD of oWebGrid1

            End_Procedure

(Note: cWebGrid1 is actually a cWebList)

Invalid CDS Node

chuckatkinson — Tue, 18 Jun 2013 19:35:33 GMT

Just had this happen in 17.1 Beta5.

Here's a screenshot (008) - (somehow the copy error to clipboard got cleared or something)..

BTW - makes closing the studio very difficult as each mouse movement throws the error.

The 2nd screenshot (009) shows there should be 4 procedures in cWebForm1. But when the error occurs you can see that (?) in the nodes in screenshot008.

Date Lookup - cWebDatePicker issues

Nigel Sedgley — Tue, 18 Jun 2013 16:20:00 GMT

Hi All,

I'm having some issues getting a user-friendly popup working on a date field.

What I would like is to have a calendar lookup on a date field.

There are 2 options to do this 'out of the box'.

I can either use a cWebDatePicker control, which embeds a datepicker into the web page, or I can use a cWebDateForm, which is a
subclass of the cWebForm with a datepicker built in as a prompt object.

There are a couple of issues with the popup on the cWebDateForm.

The first is that the datepicker pops up top-aligned with the control, and if the control is near the bottom of the container control, only the top of the datepicker is visible, until you scroll down to view it, and if the container is shorter than the datepicker, then you will never be able to see the whole of the date picker at any time.

The second is that there is no way to cancel the popup without selecting a date, although I have found that it cancels the popup if I re-click on the prompt button on the invoking control - which means that the prompt object is not truly modal!

There are different issues when using the cWebDatePicker itself as the control.

The first is the space that it takes up, although this is a matter of choice and there may be times when the control is more intuitive to use this way.

A more major issue is that when you select a month or year from the dropdowns, or use the previous/next buttons to change the displayed month, although this displays the month selected, when you click on a day in the body of the calendar, it usually just re-displays the original month with the original date selected, i.e. it doesn't select the date clicked on and the onDateClicked event doesn't fire, although strangely sometimes it does work.

By creating a CalendarPopup modal dialog, and creating a sub-class of the cWebForm to use this popup as a prompt object, I have created a
control that will include a datepicker as a prompt object.

This gets around the display problem if using a cWebDateForm in a small container as it is a modal dialog so sits 'above' the control and its container.

It also allows me to have a button to Cancel the popup, but it still has the issue regarding selecting dates in other months as it uses the cWebDatePicker so doesn't reliably allow a single click on a date to return the date.

Another issue with this solution is that the modal dialog pops up centred on screen. I can locate the modal dialog by setting piTop & piLeft, but I can't find out what these should be set to as I can't get the location from the invoking control. I suspect that this is because the control doesn't 'know' where it is, having been located according to 'flow'. It would be nice to have this located near the control that popped it up, but I can probably live with it centred on screen.

Can anyone shed any light on why the cWebDatePicker is unreliable when trying to select dates in different months, or if there is any way I can get the location of the invoking control for a popup, or is there some other way that I can get a user-friendly date lookup?

TIA

CodeJock Ribbon Bar, ComOfice2007Images missing

Frank Cheng — Tue, 18 Jun 2013 15:07:30 GMT

Hi all,

Our current app is on VDF 16.1. I tried compiling our app in VDF 17.1 Beta 6, and I got a compiler error
ERROR: 4306 Forward reference not resolved SET_COMOFFICE2007IMAGES ON LINE: 516 (156858) OF FILE: .\MYCOMMANDBARSYSTEM.PKG

In VDF 16.1, the cCJCommandBars.pkg has that "Procedure Set"
In VDF 17.1, the cCJCommandBars.pkg doesn't have that "Procedure Set"

I know that VDF 17.1 uses different version of the CodeJock controls. Does anyone have a workaround for this problem?

Thanks in advance,

Frank Cheng

Calculated column in the new web grid ?

BO Lincoln — Mon, 17 Jun 2013 20:34:20 GMT

Is it possible to have a calculated column in a data aware web grid in 17.1 (Beta 5) ?
This would be a column that has no corresponding field in a data table.

Closing a WebApp - Revisited

philby — Mon, 17 Jun 2013 12:08:12 GMT

JVH - you suggested we start a new thread on this subject if necessary.

In my previous postings on this topic, I was searching for hooks and methods of closing my webapp properly, given there are a number of ways a user can perceivably close the app down.

1) Programmed non-response Timeout
2) Close the browser page
3) Click a Close button in a dialog or view title bar
4) Click a "Logout" button in the webapp itself

So far, I have only been able to confidently implement code for 4)

Experimentation with 1) left my app non responsive, or throwing ugly timeout errors that I would not want a production version of my product to present.

I cannot find any further clues in the documentation, and feel there is a need to know how points 1), 2) and 3) might be managed.

I appreciate there was some discussion on how this might be achieved in the original thread, but I think the subject is rather complex (particularly if one's only experience with web development is VDF17.1Beta) and needs some guidance from the experts. To me, this seems a fairly important set of behaviors to get right, otherwise a genuine logout may not really have transpired, with some serious consequences.

Regards,
Phil

Run the web order app.
Open order view.
Find an order.
Click down to grid to blank row as if to create a new sale item row.
Change mind.
Press Ctrl Home.
