I'm doing a Hello World data app using Power Apps. It's simply displaying and editing a list I am connecting to an Azure SQL Server. I have a a table with column called UserImage, which is a Image data type. When I go into edit mode I can add an image and I can see something getting added to the binary column. I've tried converting the image to text (thinking a url or something textual might be going in) but it's funny encoded characters. I was wondering if anyone had any ideas. The images don't display in list or view mode.
As you've noticed, the Gallery control in PowerApps doesn't provide any sort of special empty display message. You can easily add an empty message if you want one, though. Just add a Label control outside of the Gallery and bind the Visible property to CountRows(Gallery1.AllItems) = 0 (with Gallery1 replaced by whatever the name of your gallery is, of course). This will make it so the Label only shows when the Gallery is empty and you will be able to style the Label however you want.
Reference: I work on PowerApps. :)

I have created a stock taking report in SSRS 2008. I have also added an extra column in the tablix.
The extra column I added is a column I want to have the option to manually click on the checkbox if item is in stock.
I have tried using the wingdings option using the below expression:
=iif(Fields!Expr1.Value,chr(252),chr(251))
However the result I get is not the desired result, because I get about 6 winging characters back instead of the check and uncheck boxes I required
How could I go about fixing this ?
One option is to use an Indicator, but I've preferred to use images for similar situations. Embed the two needed images in the report and switch between those dynamically. (You can make standard images of your characters in MS Paint or Paint.NET.)
Images have the disadvantage that they don't print with high resolution, but they do render on most devices (not .csv) and you don't need to worry about installed fonts on the server.
As far as fixing your immediate problem, try changing the "Markup Type" for your placeholder (Placeholder Properties -> General -> Markup type.) It sounds like something is trying to generate HTML when it shouldn't be.
When I open a report from Dynamics NAV 2013 in Visual Web Developer 2010, every text box shows a field that looks like
<<Expr>>
Where << and >> are the french Guillemet characters. I find this rather difficult because I have to analyze the properties of each text box, if I am looking for a particular field.
For example in this picture, how do I know which field is the Customer Name, Phone Number or VAT Registration No?
Is there any way to configure Visual Web Developer to expand the Expression like it was in Visual Studio 2008 with NAV 6.0?
Preferably I would like to either see a label instead of the generic Expr or just the old Fields!Some_random_field.Value like it was in Visual Studio 2008.
Ah, another feature of NAV & RDLC :)
You'll find that the Expr text appears when an expression reaches a certain "complexity" -- e.g. from just a field;
=Fields!TotalText.Value
to
=(Fields!TotalText.Value)
The fields in the header are usually always Expr as the values are passed using GetData and SetData (and remain that way from NAV 2009 reports). While this limitation was somewhat removed in NAV 2013, you can only put static values in the header -- they won't change across pages which is useless for multiple SO's or Customers for example.
There isn't a way to show it in the properties box, however the quickest way seems to be to select the field, Right Click, "Expression".
I'd suggest giving the textbox a name other than TextBox to make it easier to identify fields (e.g. "SalesHeaderNo");
So after a bit of research I have found another solution. There is a View Element called the Document Outline [Ctrl+Alt+T] which shows a tree like structure of the whole report. When ever you click on an item in your report, the corresponding item in the Document Outline is selected and vice versa. This is quite useful to keep a better overview over your report and to quickly navigate between the different items.
The only annoying thing is that it also shows empty text boxes, so in a sparsely populated table, you will have a lot of textbox123 items in the outline. It doesn't seem there is a way to filter these out.
I am getting an issue with a access 2007 application that I am working on. Access acts as a front end for a SQL server 2005 backend. When I try to click on a richtext control on the form, it gives me the following error:
Because of your security settings and current security policy, this
control is disabled. To modify your policy and enable the database,
use the message bar.
After a bit of searching, the suggestiong is to add a trusted location, however this error still comes up.
Ok so I found out the cause of this issue after a lot of trial and error. It seems that the rich text box control has limited support in Access 2007. I found out that the rich text box I am using is Microsoft Microsoft Rich Textbox Control 6.0 (SP4) - RichTX32.OCX. Apparently it will cause the above error if activeX is disabled.
To fix this I modified my registry entries as follows (although this opens up security issues with IE aswell):
Open up regedit
Go to the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility{3B7C8860- D78F-101B-B9B5-04021C009402}
There should be a DWORD called Compatiblity Flags. Set this to 0 (default is hexadecimal 400)
Some additional information that I found useful follows:

I recently found this ?, and started updating the control to work. Then, I came across the right way to get rich text in a form in MSO 2007+:
Insert or add a rich text field
It says you need to have a memo field in a table, and set its text format to Rich Text. Since the solution is a bit opaque, I'll continue with what worked for me: I then go into form design, and create a text field. I set its data source to the table's rich text memo field; and its "Text Format" property to "Rich Text". I set its "Scroll Bars" property to "Vertical".
Now, I get some nice text formatting options in Access 2010; but it's kinda stupid the way they've implemented them. There's no format painter. Also, if I want to e.g. set the font to Times New Roman to pitch 11, it doesn't let me; but makes turns it into 10; although I can select 12 also - but not 11. If, however, in Design View, I set it the field's font to "Times New Roman", and set the font size THERE to 11, the font is size 11 by default. I can paste things into it in 11 pitch, by first pasting them into Notepad, to strip them of their formatting attributes, and then from Notepad into my field, to get pitch 11 text; or I can paste pitch 11 from elsewhere.
This has the advantage of getting some handy text formatting controls to light up on your home ribbon, and lets you format stuff more or less properly.
I'm trying to solve a formatting issue I'm having with Oracle Apex. Overall, this is a fantastic tool for whipping up proof-of-concept type applications, but whenever it comes to "prettying up" a page, it seems to be very difficult to work around.
I have a simple form-based page based on a table. However, I'd like to do a few simple things like group certain fields together on the form (phone info), perhaps throw an image in etc. I can't see any way to do either of these things inside a form. For example, here is an example page
and here are the small changes I want to make (photoshopped):
What the heck am I missing here? I can't seem to add anything except database fields inside the form to visually change things.
Any help appreciated.
It can be done - see this demo (I took the liberty of copying your icon, hope you don't mind). It looks like this:
How it was done
1) I uploaded the image into Apex. (Alternatively it can be hosted elsewhere).
2) I created a page item of type "Display Image" with attributes as follows:
Note the use of rowspan=3 in two places (circled in yellow), to make the picture and its (blank) label occupy 3 rows of the HTML table Apex uses for layout.
3) I created a page item of type "Stop and start table" and put it after the Mailing Address item. This prevents the phone icon taking up the same horizontal space as the name and mailing address, resulting in phone items being pushed too far to the right.
4) I set the "Begin on new line" property of the first phone item to "No" so that it appears to the right of the icon. The remaining phone items have "Yes" so that they appear below the first.
I am working on a windows form app like most development it is usually useful to see output. I am wondering what methods you use to see output in a windows form app.
PS. I am new to visual studio in general.
You can set some Labels around and display text on them:
Label.Text = "Some Text";
And DataGridView controls for information from tables, and for a better insight, you can set breakpoints in your code by clicking the far-left part of your code editing area. When the program reaches to that point it'll stop and you can hover your variables and objects for a better view of their insides...
Oh, and also VS has a "Locals" window when you run your project, that shows all the objects and variables being used and some information about them.
the user interface (a grid or other
controls on a form)
a report (like Crystal)
a file (.txt)
a database table updated
