It may seem tempting to write do-it-yourself validation by responding to a control s LostFocus event. Unfortunately, this approach is dangerous, because it s not safe to change the focus inside a LostFocus event handler. If you try to direct the user back to the original control, or if you change the focus in another way (for example, by showing a message box), you ll end up triggering an additional LostFocus event from the target control. If both controls have invalid data, they may fight endlessly among themselves, trying to move the focus somewhere else and trapping your program in an endless loop.

Tip If you don t want to perform validation, but you simply want to update some part of your user interface when focus changes from one control to another, you still shouldn t use the GotFocus and LostFocus events. Instead, use the safer Enter and Leave events. You ll notice that both GotFocus and LostFocus are hidden from the Properties window to prevent accidental usage.

Proxy authentication addresses the anonymity problem with standard username/password authentication. The solution is simple since Oracle has no idea of knowing who the actual users are, why not just declare the actual users in the connection string as well! In proxy authentication, two user accounts are passed in via the connection string for authentication: the actual user s credentials and the pooled (proxy) user s credentials. It adds two new keywords to the connection string: Proxy User ID and Proxy Password. For example, if Thomas accesses the database, he will use the following connection string:

.NET handles this problem with the Validating and Validated events. These events occur between the Leave and Enter events. For example, if you tab from one text box to another, here s the sequence of events that occurs: 1. Leave (TextBox1) 2. Enter (TextBox2) 3. Validating (TextBox1) 4. Validating (TextBox2) 5. LostFocus (TextBox1) 6. GotFocus (TextBox2) The Validated event allows you to respond to correctly entered data. The Validating event is more useful. It allows you to verify the data and, if it fails the test, stop the focus from moving to the new control. Validation takes place only if the source control (the control to be validated) has the CausesValidation property set to True. In addition, the validation won t take place until the focus changes to a control that also has its CausesValidation property set to True. If either one has a CausesValidation of False, the validation events are suppressed, but the other events (like Enter and Leave) still fire. Table 18-1 shows some examples of what can happen when tabbing from one control to another. Finally, it s important to note that you can switch off this behavior entirely by setting the Form.AutoValidate property to AutoValidate.Disable. In this case, the validation events will never be fired, no matter what you set for the CausesValidation property of your controls. You can set the AutoValidate property for any container control (panels, group boxes, and so on). Use AutoValidate.Inherit to acquire the settings from the parent control or form.

glTexCoord2f(0, 0) glVertex3f(-300, -300, 0) glEnd() pygame.display.flip() # Delete the texture when we are finished with it glDeleteTextures(texture_id) if __name__ == "__main__": run() The run function performs the five steps required to read in the sushitex.png image and upload the image data to OpenGL. It then draws a textured quad by sending OpenGL four texture coordinates and four vertices. Texture coordinates are sent with the glTexcoord2f function, which takes the s and t components as parameters. An alternative to glTexcoord2f is the glTexCoord2fv function, which takes a sequence (tuple, Vector2, etc.) rather than individual values. The rotation is done with the glRotate function, which creates a rotation matrix about an axis and multiplies it by the current model-view matrix. It takes four parameters: the first parameter is the angle you want to rotate by (in degrees), followed by the x, y, and z component of the axis. For example, a call to glRotate(45, 1, 0, 0) would rotate 45 degrees around the x axis, and a call to glRotate(-30, 0, 1, 0) would rotate negative 30 degrees (i.e., 30 degrees clockwise) around the y axis. You can also use this function to rotate around any axis, and not just the three basic axes. When you run Listing 11-2, you will see something like Figure 11-2, with a large textured quad rotating around the x axis. Try experimenting with the texture coordinate values to see the effect they have on the quad.
