go into your Crystal Report designer (the .dsr or rpt file you are using) right click on the field or fields you want to hide. In the format section, there is a "suppress" option. Check this option. To the right of this check box, is a code/formula box. Click on this, and code the suppression formula you want to use such as:

If isnull({table.myField}) Then
True
Else
False

Limited or no connectivity to wireless network??

This happens with anyone of the following:

Checklist:

1. Most of the time this is a wireless security issue. When you view available wireless networks and see a pad lock on the network you want to connect to, then you need a network key that you can get on the wireless access point's set-up utility.

2. Wrong wireless network key will give you the same result.

3. DHCP is turned-off on the wireless access point. For security purposes, some configure their access points to disabled DHCP. This means that you're not getting an IP address even if you getting signal from the wireless AP/router.

4. DHCP is turned on, you know the network key and it's correct but you're still getting the same error - You need to look into access restrictions on the wireless AP called MAC filtering. This means that your computer MAC address (your ethernet adapter's physical address when you go into the MSDOS prompt and type "ipconfig/all") is not yet included in the wireless computer that can connect to the AP.

5. You're too far - Sometimes you're too far from the AP that the wireless signal is not good enough for the 2 devices to successfully communicate. How do you know? If you go nearer you get online, if you go farther, you get low signal and "limited or no connectivity" error message.

6. You or someone else set a static IP on the computer. You should always have this as set to automatic unless you have server running on that computer which not everyone has. Chances are, you just want to get online wirelessly which is why static IP is not normally used in these situations.

It can be used if you're connecting but losing connectivity after a while because or low signal. Set static so the PC won't have to worry about trying to get an IP from the wireless router. The only problem is that you've have to disable it again when you go to nearest coffee shop, friend's house or the office wireless network.
