Visual Basic Q&A

Symptoms
You have a Visual Basic ActiveX DLL that has a method that takes an array of Scripting Dictionary Objects as an argument. It may work fine when your Visual Basic client is run in the Visual Basic integrated development environment (IDE) by using this method, but when you run it as a compiled application, you get the following run-time error message:

Run-time error ‘-2147417848 (80010108)’:
Method ‘~’ of object ‘~’ failedThis only occurs when you use late binding to call the method.
Resolution
Use early binding to work around the problem.

Symptoms
With Microsoft Visual Basic 4.0, when you set the Text property of a MaskEdit control at run-time, you receive the following error.

Run-time Error 380:
Invalid Property Value
Resolution
This error occurs under the following circumstances:
The Visible property of the Mask Edit control is set to False atdesign-time.
-and-A later version of MSMASK32.OCX is installed. The error occurs withMSMASK32.OCX version 5.00.3714, which ships with Microsoft Visual Basic5.0.

Symptoms
When using some controls bound to an ADO Recordset object, the EditMode is not set properly when you modify the data through the bound controls. These controls include the Microsoft DataCombo control.
With other controls bound to an ADO Recordset object, the EditMode is set properly when data is changed through the bound controls. These controls include the TextBox.
The expected behavior is that the EditMode is set properly for each type of bound control.
Resolution
The affected controls do not notify the Binding Collection that they are dirty.

Symptoms
When you use the Data Form Wizard, queries or views do not appear in thelist of available record sources.
Resolution
The Data Form Wizard incorrectly queries only for tables to populate thedrop-down combo box of available record sources.

Symptoms
Pressing the ESC key while the cursor is in the SQL text box of theGeneral Tab in the property page of the Remote Data Control causes a blankGeneral tab. When you click the Colors tab and then click the General tabagain, an application error occurs and Visual Basic ends. The SQL text boxcan be empty or contain characters. Clicking the Cancel button on thewindow correctly closes the window. This behavior only occurs under theWindows 95 operating system.To work around this behavior, programmatically set the properties ofremote data control or use the Properties window of the Remote Data Objectto set the properties.
Resolution
Microsoft has confirmed this to be an issue in the Microsoft productslisted at the beginning of this article. Microsoft is researching thisissue and will post new information here in the Microsoft Knowledge Baseas it becomes available.

Symptoms
A private UserControl loses it Data Bindings when compiled to an EXE.
Resolution
Close the form containing the UserControl before making the EXE.
