Set External Context
You can set up an external context when launching your application. This is especially helpful when starting an app from somewhere else, for example a robotic process automation (RPA) process.
To try setting the external content yourself, use the demo app or follow the procedure.
-
Run the demo app. All the expressions using the
App.QueryParamfunction should display their default values. -
To reset expressions to their default values, click the Next page button.
-
Copy the following syntax and append it in the app URL after the
el=vbpart:&intv=3200&guidv="81a130d2-502f-4cf1-a376-63edeb000e9f"&sv=queryparam&bv=true&dv=1000000.222&datetimev="2/1/2022 11:00:00 AM"&datetimeoffv="4/2/2007 7:23:57 PM"&listv={"data":["apps","engineering","team"]}&file={"Name":"image","FileSize":25}&intv=3200&guidv="81a130d2-502f-4cf1-a376-63edeb000e9f"&sv=queryparam&bv=true&dv=1000000.222&datetimev="2/1/2022 11:00:00 AM"&datetimeoffv="4/2/2007 7:23:57 PM"&listv={"data":["apps","engineering","team"]}&file={"Name":"image","FileSize":25} -
To display an image in the document viewer, add
URL="https://my-public-image-URL"in thefileparameter. For example:file={"Name":"image","FileSize":25, URL="https://my-public-image-URL"}file={"Name":"image","FileSize":25, URL="https://my-public-image-URL"} -
Press Enter and watch the values being updated.
Note:
To reference the external context using VB expressions, use the
App.QueryParam() function.
Query parameters are case sensitive For example,
intv and INTV are treated differently.
- Add a Textbox control.
-
For the Text property, open the Expression editor.
-
Bind the query parameter function to the Text property by using the
App.QueryParam()function:App.QueryParam(Of Integer)("intv", 100).ToStringApp.QueryParam(Of Integer)("intv", 100).ToStringImportant:Inside theApp.QueryParam()brackets, specify the data type of the value you are passing in the URL. For example, if the value is an integer, you need to specifyApp.QueyParam(Of Integer). - Publish the app. At the initial runtime, you should see the default value specified using the
App.QueyParam()function, which is100. -
Add query parameters after the
el=vbpart in the runtime URL by using the&character, then press Enter. For example,el=vb&intv=250.The textbox should display250.
