messagebox bug

[Richard Bond]

Hi,

Messageboxes emitted from my vb.net windows forms applications have suddenly
stopped rendering messagetext and button text. What is the best plan of
action regarding components to try repairing/reinstalling?
(I have already reinstalled the framework to no avail)

Line of Code example:

MessageBox.Show("Some display text.", "An Example Title")

The title is displayed correctly however messagetext and button text are
missing.
The same codes works fine on other machines, and vb6 apllications work fine
on my pc.

OS = Windows Server 2000
Framework Version = 1.1.4322 SP1
Development Environment = 7.1.3.088

I am beggining to get quite disappoited with .net quirkiness in general now

regards,

Richard

Have you recently installed or upgraded any virus scan software?
There is a known bug in McAfee v8 that can cause exactly what you are
seeing, or not as the case may be.

absolutely spot on!

I had my virus scanner remotely updated to McAfee v8 today.
Is there a patch I can download?

thanks very much for the reply,

Richard

(P.S. apologies to MS this time round)

MessageBox.Show("Some display text.", "An Example Title")

The title is displayed correctly however messagetext and button text are
missing.

This behavior is caused by buffer overflow protection of McAfee AntiVirus 8.
By installing available updates the problem should go away:

<URL:
| After last update (now I have VirusScan Enterprise
| 8.0.0 with Scan engine 4320 and Buffer Overflow
| Protection Deifnitions 131; Patch Versions
| 1, 4, 5, 7,8, 9) the problem disappeared!

In Virus Scan Console, disable buffer overrun protection.
