Test Text

2. Open the Menu Editor, and create a top-level item with a Caption value of PopUpFormat and the Name mnuPopuUpFormat. Also importantly uncheck the Visible checkbox (see the circled item in figure). In order for a menu to be a pop-up menu, it must be invisible.

5. Click OK to save your changes. Note: When you return to the IDE, we will NOT see this menu on the form (remember it's a pop-up menu, and it will only be visible when invoked through code).

6. Code the lblTestText_MouseDown event as shown below. Note that the Button parameter is tested for vbRightButton as is conventional, we only want to pop up the menu if the user right-clicks on the label. If the user clicks the right mouse button, the PopupMenu statement is executed. It is this statement that makes the pop-up menu app

Procedure:

Creating an database using MS Acces

1. Start – Program – Ms office – click Ms Access. 2. create a table as shown in figure 3. Save the table as table1. and save the database as db1.mdb

Creating an ADO Data Control

1. Add the Microsoft ADO DataControl 6.0 (OLEDB) from the Project, Components menu dialog box, as in Figure 8.13. The ADO Data Control icon should now appear in the VB toolbox.

2. Place an instance of the ADO Data Control on the form

3. Change the control's Name and Caption from their default values. Set the ConnectionString property using steps 5–9.

4. Click the ellipsis next to the ConnectionString property in the ADO Data Control's Properties window to bring up the Property Page dialog box for this property ConnectionString property.

5. As Source of Connection, choose one of the following three options:


G.U.I LAB MANUAL

• Use Data Link File. If you choose this option, you will be able to click the Browse On the Provider tab of the Data Link Properties tabbed dialog box, choose an OLE DB data provider, such as Microsoft Jet 4.0 OLE DB
