Report nonblocking status
Update status without interrupting the user’s task.
Status belongs near the workflow it describes. The save action in this sample demonstrates a message transition; it is not a substitute for actually writing data. When adding persistence, show success only after the operation completes.
Step 1Prepare a safe practice project#
Extract the archive into a new writable folder, separate from your own application. Open StatusBar.mcbproj in McBasic™. Keep every declared source, layout, resource and migration file together.
To reconstruct it yourself, create a DesktopApp project and add the files declared below. In the complete project, follow these steps as a guided rebuild: replace each named source file once and Check after all its procedures are present.

}Step 2Build the Form and set its properties#
frmMain
Select the Form first and set its properties. Add containers before their children. These are initial Designer values, not statements to paste into a procedure.
| Form property | Value |
|---|---|
Caption | "StatusBar — McBasic" |
Width | 600 |
Height | 360 |
MinWidth | 480 |
MinHeight | 280 |
| Type | Name | Parent |
|---|---|---|
| Label | lblMessage | Form |
| CommandButton | cmdSave | Form |
| CommandButton | cmdClose | Form |
| StatusBar | staMain | Form |
lblMessage · exact Inspector values
| Property | Value |

staMain · exact Inspector values
| Property | Value |
|---|---|
Left | 48 |
Top | 292 |
Width | 480 |
Height | 26 |
Text | "Ready" |
TabIndex | 3 |
| Anchor edges | Left, Right, Bottom |
Step 3Connect the events explicitly#
frmMain
| Object | Event | Procedure | Parameters |
|---|---|---|---|
cmdSave | Click | cmdSave_Click | Click() |
cmdClose | Click | cmdClose_Click | Click() |
| Form | Load | Form_Load | () |
Step 4Enter the complete behavior#
Open the named source file. Enter declarations first, then every procedure. Expand a procedure for its full body, or copy the complete file. Helpers are required: do not stop after entering the first Click handler.
Forms/frmMain.bas
Enter these declarations at file scope, before the procedures.
Option ExplicitPrivate Sub Form_Load()
Initialize state before enabling dependent actions. Keep the shared declarations and startup dependencies with this procedure.
Private Sub Form_Load()
staMain.Text = "Ready"
End SubPrivate Sub cmdSave_Click()
Enter the complete action, including its input checks and calls to helper procedures.
Private Sub cmdSave_Click()
staMain.Text = "Saved from McBasic."
End SubPrivate Sub cmdClose_Click()
Enter the complete action, including its input checks and calls to helper procedures.
Private Sub cmdClose_Click()
Unload Me
End SubCopy the complete Forms/frmMain.bas file
Replace the file once; do not append duplicate procedures.
Option Explicit
Private Sub Form_Load()
staMain.Text = "Ready"
End Sub
Private Sub cmdSave_Click()
staMain.Text = "Saved from McBasic."
End Sub
Private Sub cmdClose_Click()
Unload Me
End SubStep 5Keep resources and storage reproducible#
No external resource or migration files are declared. Any inline migration, seed data or local JSON is present in the code above. Runtime application data and private preferences are not included in the archive.
Step 6Check, run and test the result#
Save all files and run Check. Resolve diagnostics before Run. Developer CLI users can work from the extracted folder:
mcbasic check StatusBar.mcbproj
mcbasic run StatusBar.mcbprojAcceptance checklist
- Inspect the initial status.
- Activate Save and read the changed status.
- Resize the Form and check placement.
Step 7Make one change and repeat the tests#
Show a busy message before an asynchronous operation and replace it only after success or failure.
Save a working Git checkpoint first. Change one behavior, Check again and repeat the acceptance checklist. Compare with the downloaded solution if a regression appears.
