Upgrading a Visual Basic Application to Use LEADTOOLS 16

These instructions describe how to upgrade a Visual Basic application from LEADTOOLS 12.1 to LEADTOOLS 16. You can also follow these instructions when upgrading from an earlier version of LEADTOOLS.

Upgrading requires the following steps:

1. Install LEADTOOLS 16. Note the following:

By default LEADTOOLS 16 is installed into a different folder than previous versions.

2. Remove old controls. Working with the old project, do the following:

a. Find and remove all of the LEAD controls from your forms. Before removing a control, note the control Name and any other non-default properties. (You can use the tab key to make sure that you find all of the controls on a form.)

b. Remove the old LEAD control from your project's toolbar. To do so, select the Tools > Custom Controls option, uncheck the LEAD Control (12.1) control, and click OK. (If a message tells you that the control is in use, there is still a LEAD control on one of your forms.)

3. Replace old controls with new ones. To do so, take the following steps:

a. Select the Tools > Custom Controls option, check the LEAD Control (16) control, and click OK. (The LEAD icon appears on your toolbar.)

b. Use the new LEAD control tool to recreate the controls that you deleted earlier. For each control, set the Name and other properties to be the same as the previous control.

4. Run your program to test it.
