I want a button from the command line bar to be visible or invisible depending on whether a record has been selected in the lookup field from the main form or not.
If no record has been selected, then the button should be displayed. Otherwise not.
For this problem, I want to use the Power Fx in PowerApps, but I haven't found a command yet, which shows me the content or something like that of the lookup field. Other field data types like text have worked without problems.
With Javascript, I already managed it without problems, but I would like to do it also in PowerFx if that should work.

The records come from the Table Company, where the attribute is Companyname.
Commands where I think they might work:
If([Selected Record];true;false);If(IsBlank([Selected Record]);true;false);If(IsBlankOrError([Selected Record]);true;false);If(IsEmpty([Selected Record]);true;false)
I guess there are 2 scenarios:
The Lookup form control element is a Dropdown with a Selected output property. Then your approach would work like If(IsBlankOrError(DataCardValue1.Selected),true,false)
If your form control element is a ComboBox then you could use If(CountRows(DataCardValue1.SelectedItems)>0,true,false) or the above described IsBlankOrError.
So basically I'm new to oracle apex, i have created a blank page in an mobile application in apex and then created a static region having a select list.
Noticed that the select list item is to the right of the screen, i know i can use css to move it to the required spot, but when I did a page inspection, noticed that #BODY# had other divs as well and wanted to know whether the divs or spans under #BODY# can be edited, if so from where and how?
OK then, a Select List item it is.
Select it
in its properties (on the right hand side of the screen), you'll see the Layout section
in there, there are some properties you might find interesting
column - set to "Automatic" by default, and yes - it positions the item "right" on the screen (I don't know why Apex authors decided to do it that way; I'd be happier if it was "left"), somewhere to the 4th of 5th column. What does that column mean? When you run the page, there's the bottom toolbar available to developers. In version 5.x, there's the option (I can't remember its name; most probably it is "Show layout columns") which enables you to show the grid - you'll see vertical "lines" (columns) and see where's each of your items positioned. On Apex 18.1 (available at apex.oracle.com), you'd click "Page info" and select "Show layout columns".
so, if you want to move it left, set the "Column" property to 1 (1st column on the screen)
modifying the "Column" property might require adjusting two additional properties: "Column span" and "Label column span".
I suggest you try to set those properties to different values and see what happens. Apex will inform you if you set something irregular.
While working with Perl and Gtk2, I have to programmatically remove an option from a drop-down (ComboBox). While I'm aware that $combo_box->remove_text ($position) will do the trick in one shot, I need to remove the option based on its name (entered by the user).
I'm unable to find a method that can return the index of an item by its name. Could someone help out?
It's a bit unclear what you mean by "name"; combo box items don't have names. If the combo box is textual, then each item is made up of text, but that text isn't a name. You could have the same string in all items for instance, which would make it very unclear which one you want to delete.
I think you're going to have to implement it youself, by iterating over the combo box's underlying tree model. Then it's up to you if you want to just delete the first match, continue searching to find all of them.
I had an editable pdf with checkbox, after selection i flatten that pdf. from that flatten pdf i need to read the checkbox selection which is looks like crossmark(X), is there any possibility to read that checkbox selection.
When you flatten a PDF, you take away all interactivity. If you have a check box field in an interactive form, and you flatten that form, the check box field is gone. That is the concept of flattening.
What happens in practice?
A check box field has two appearances. One appearance is Off. This appearance can be a path such as a simple square defined as a rectangle. Another appearance can have any name On, Yes, 1 or whatever is defined in the original form. The corresponding appearance can be the same square as the Off appearance with two extra lines that look like a cross, or the square with a character that looks like a check mark, or whatever was defined in the original form.
When you flatten the form, you throw away the name of the check box field, you throw away the widget annotation that corresponds with the field, and you throw away one appearance state (depending on the value of the check box field). The only thing that is left, is one of the two appearances.
If you no longer have the original form, you have no clue as to what this appearance could look like, hence you have no idea what to look for, nor where to look for a specific appearance.
You say that the appearance looks like a cross mark in your case, but whoever reads this question has no idea if this cross mark is a path that was constructed in graphics state, or a glyph that was added in text state.
Long story short: if you flatten first and then expect to be able to read a field value, your design is seriously flawed.
You have to ask yourself: why do I need to flatten the form? Maybe it's sufficient to make the fields read-only. If that's not sufficient, why don't you add an attachment to the PDF that contains the original field values? There are many different ways to work around your problem.
I have a subform bugging me. The mainform contains buttons etc. Everytime the user close/open the form, the columns width is reset to whatever the table likes. If i open the table directly, the size is as i want. If i change it in the subform, it is not saved. (See screendump)
I would like "Phase" to stay about 2 cm width. I can enter the subform and edit the "Width" but that is only applied to the other views.
I hope you can help, Emil.
I realize this post is almost 2 years old, but I ran into the same problem and came across this post.
I am running MS Access 2013 on Windows 7 Ultimate. I did not find the solutions offered here to work for me, so, I set out to find something that would work for me before I went to VBA code. (Incidentally, I appreciate the link offered by #Patrick_Honorez in his comment on the original post because that was going to be my fall-back solution.)
Anyway, here is what worked for me and I hope perhaps it will work for others as well:
Open the parent form.
In the subform, right-click the column header
for the column for which you wish to adjust the width.
Select the “Field Width” item from the context menu.
In the “Column Width” dialog that appears in step 3, enter the desired column width in points, or, use the [Best Fit] button. Then click the [OK] button to close the dialog and return to the form.
Right-click the parent form’s border to bring up the parent form’s context menu. Click the “Save” item in the context menu.
Now close the parent form.
The next time the form is loaded, the column widths should be as set it step 4 above--at least they are for my setup.
I see this post is quite old and OP must have figured someway to tackle the issue. I came across same issue today and found solution on this link.
For anybody else having same issue, use following code (I modified the code a little because original code from the above mentioned post saves column width of only text boxes but my form has combo boxes too, column width of which was not getting saved) in close and open events of your subform and then open main form in Form View and then manually select desired widths either by mouse, by entering column width value or using best fit. Save the form and reopen to check results. That's it.
Private Sub Form_Close()
Dim ctrl As Control
For Each ctrl In Me.Controls
If (ctrl.ControlType = acTextBox Or ctrl.ControlType = acComboBox) Then
SaveSetting "propertiesDBS", Me.Name, ctrl.Name, ctrl.ColumnWidth
End If
Next
End Sub
Private Sub Form_Open(Cancel As Integer)
Dim ctrl As Control
Dim frm As Form
Dim w As Long
For Each ctrl In Me.Controls
If (ctrl.ControlType = acTextBox Or ctrl.ControlType = acComboBox) Then
w = GetSetting("propertiesDBS", Me.Name, ctrl.Name, 0)
If w <> 0 Then ctrl.ColumnWidth = w
End If
Next
End Sub
I know this is late to the party and most likely going to be the last comment anyone reads, but this can be done quite simply in MS Access 2016 - by someone like myself who has no more than 4 days experience in databasing overall and no experience with writing custom Macro's or VB Script (using only what is native to MS Access).
Here's how I did it.
Scenario - Split Form (Form + Datasheet).
Extra Recommendations:
It pays to be across all properties of every object type in your database, as a change in a field property can cause unpredictable erratic effects, which take ages to figure out why it happened and how to stop it from happening again, whilst delivering your desired outcome.
Me.Requery in your VBA script after every necessary event and also in your main form (generally the 'After Update' event is used most), and be wary that too many Me.Requery's (in unnecessary events) can also be detrimental - so too much of a good thing can be a bad thing.
Bottom Line Up Front - Modify the format of your query that is to be exported/printed.
In 'Design View' of the query you are concerned with, ensure that the fields are in the order you need them outputted in first as this is exactly how the macro will present them for export/print (example could be "Australia" then "Northern Territory" then "Town's In The Northern Half Of The State" then "Darwin" then "Suburbs In The Northern Half Of City").
Switch to 'DataSheet View' in the same query and use the top left folded over triangle looking thingy to highlight the entire data set then right click that same triangle to present an options menu. Select 'Row Height' and type in "15" (default row height in Excel).
Deselect the entire spreadsheet and this time select every column (left click the left most column, hold shift button, scroll over to the right to the far end of the data set and click the last column) and then right click one of the highlighted columns to present another menu. Select 'Field Width' and within that new pop-up menu select 'Best Fit' and then 'OK'.
(Optional - not sure if this helps or hinders but I did it for my purpose) With the columns still selected right click one of the highlighted columns again and select 'Freeze Fields'.
My scenario had buttons with macros configured to run filtered reports so I was able to check this by simply clicking any of those buttons and seeing the report formatting, which it held true to the work I had just done. I exported using another button with a macro that exports to Excel with 'Print Formatting' selected (my main form also had the datasheet view as the only thing that could be printed and was also set in 'Print' formatting.
The Excel spreadsheet opened with all row heights and column widths in a way that I could read every field/record with perfect ease and without extra modification.
This also worked for cascaded combo boxes, with the export only outputting the 'drilled down/filtered' datasheet records, in a format that required no further modifications.
Hope this helps someone, as its saved my hide! :)
Open the Main form in Design. Go to the SubForm. Click on the square at the top left of the SubForm and select 'Properties'. Right-Click the control 'Phase' and click 'Properties'.Click the 'Format' tab and select 'Width'. What do you see there? That should control the widht of control 'Phase' unless you have some overriding coding elsewhere. Input the size you want and see what happens.
Use continuous forms instead. It gives you complete control over how your subform displays.
If you open your subform directly, your property sheet menu should display automatically if the default view is "Datasheet." Click on "All" and change the "Auto Resize" property to "No." This should solve the issue and avoid the need for VBA.
This only works when you open the subform separately. So if you want the changes to be reflected within your main form, you'll have to close it and switch back and forth.
Super annoying by default.
It seems to work as one would expect of you set the view mode to layout view. Drag column widths as needed and save. Go back to form view and it works. It's really dumb it doesn't work the same way in form view our design view.
In Access 365, open main form, right-click sub-form datasheet columns that need width adjustment, use the Field Width to adjust, click on border of main form to select Layout view, and save changes.
Open subform in datasheet view (by double click on subform in the left pannel)
Resize columns as you want by dragging or by right-click the column header for the column for which you wish to adjust the width and select the “Field Width” item from the context menu.
Right-click the subform border to bring up the context menu. Click the “Save” item in the context menu.
Either open the Main Form in Layout View or directly open your Subform in Datasheet View. Right Click on the Field Header, select Field Width, and enter the desired width. Save. Bewm.
My solution (Access 2016) was to create the main & subform, recreate the subform on its own using form wizard and set it up the way I want it, rename the original subform to something else, and finally rename the recreated subform to the original form name. Open the main form and the subform should be laid out the way you want it. You can then delete the original subform you renamed.
