Empty MessageBox / McAfee problem - any news ?

[Werner Keilholz]

A MessageBox("Hi there") in .NET 2003 / C# displays a blank (empty)
window on XP if McAfee antivirus is installed.

This is due to the JPG buffer overflow ckeck in McAfee, and a patch has
been released by McAfee (see below for details).

Is there a different solution for this problem ? (Without updating the
entire project to 2005 / knowing if the user has McAfee).

Thanks,

Werner

Werner,

I know this doesn't sound like a solution, but I would think there are
more people who don't have McAfee installed than do. I would just have a
knowledge base article or something of that nature indicating the problem
when running with McAfee. This is an issue with McAffe, not your program or
..NET.

Hope this helps.

Hi,

A MessageBox("Hi there") in .NET 2003 / C# displays a blank (empty) window
on XP if McAfee antivirus is installed.

I use Symantec both at home and at work so I had no idea of this.

Is there a different solution for this problem ? (Without updating the
entire project to 2005 / knowing if the user has McAfee).

I don't think so, it's a problem with your AV soft, it has nothing to do
with the framework.

Question, why upgrading to 2.0 resolve this issue?

McAfee has a hotfix that should take care of the problem. It's not limited
to dotNet either. I must've spent 3 days trying to track down a
(non-existant) bug in my VB6 software for someone. I ended up giving them a
refund because I couldn't reproduce the problem. Since I've never owned a
McAfee product, I had no clue. About 3 months later, I find a post in one of
these groups that pointed to a McAfee hotfix. I just about had a freaking
cow.

IMO, McAfee / Norton are just as bad as the virus infections they're trying
to prevent. I use AVG free version and haven't had a single problem...
period.

Let's all sing the "I hate McAfee" song... 1... 2... 3... GO!

I wouldn't install a McAfee product if I had a free lifetime subscription...
They not only cost me several hundred bucks for that refund, they also wiped
out my entire OE message store and made it impossible to do *anything* with
OE from that point on... which forced me to switch to Thunderbird... which
is "ok" but I prefer OE.

Note that you'll have to contact Customer Support (hard to say that with a
straight face <g>) for that hotfix now as the link is broken (they probably
ran one of their products on their website and broke everything)
