Subject: CXTPReportControl Scrolling Very Slow

As anyone noticed the report control scrolling being incredibly slow?
 
I have a user using my product and they scroll a report control with only 20/30 records and it is visibly a half-second beyond in its dragging ... even when using the mouse wheel. Totally unusable. Wherease 3 others (including me) its instant.
 
However, I tried the ReportSample and modified to call the "AddSampleRecords" function multiple times (12), and now that is really really slow even on my machine (its not got thousands of items).
 
It doesnt make any difference if i turn off grouping, or remove the virtual GetItemMetrics function so I dont know why it is slow.
 
The Grep sample works fine with 10,000 items in it (searching for "the" on my D drive).
 
I am confused, where should I look? Its not my code as your sample exhibit the slowdown?
 
Heres part of a profile I ran from VS6:

Hi,

I can only imagine such effect if you're building sample with the toolkit in Profile/Debug mode, or with profiling of some tool like BoundsChecker. Otherwise, it should be working fine.

Any more details on changes in sources? Other details?

Its your standard 2006 Q2 sample source with the only change being me duplicating the "AddSampleRecords" function 12 times.
 
Its slow in debug and release ... i only added profiling afterwards to see where the slow down might be and for the purpose of this post.

Is a Preview mode enabled?

Yes, preview is enabled

Actually its slower with Preview disabled. Its real jerky. It seems to be less jerky the more columns I remove or whether its the type (num/date) of column thats causing the problem I am not sure

Please let us also know your OS, screen settings (color depth) and processor speed

Well, this doesn't actually help to identify a problem 

Could you please attach there a sample solution with your modifications implemented? This could probably help further...

As above, I just opened your ReportSample project and modified it to call the "AddSampleRecords" function multiple times (12).

That was all I did, and the view became quite slow.

Hi Dan,
 
have you got any response until your last post on this issue? Did you find a solution meanwhile?

No and no. Still waiting really ... why do you have a speed issue as well?

Guys,

Sorry, but we simply can't reproduce this issue. It work pretty fine being added 12 and 12*12 times....

I still suspect that the problem is somewhere in your environment details. Locale, or screen resolution, or Service Pack not installed.

Can you find something specific in your settings, what differs from regular WinXP SP2 English (US) ?

Nothing unusual with my system, standard WinXP Pro SP2. And on two other standard development machines with the same/similar configuration.

One machine is totally unusable and you cant scroll up/down without it lagging behind about 1/2 seconds, mine just slows down a bit.

I know that tools using hooks, such as Spy++, can crash the SkinFramework completely. Maybe you have advanced hooks installed? Perhaps it could be a good idea to list which AntiVirus you are using. No debugger in memory?
 
Just an idea...

Yep, that's the good point.

Also, I've spent again spent a few hours trying to reproduce this problem.

On workstations with all available for me configurations it works fast enough.

Please run on the debugger and check the trace log for any exceptions.
For example, what I saw a few years ago, COleDateTime::Format() sometimes (very seldom) throw exeptions on none English locales (or localized OS) (in my case it was French).
 
May be on your machine there is also reproduced some unusual behavior which works fine on other configurations.
 
Try to download latest version sample (10.4.2) and run on your "problem" machine.
Does it works with the same performance as yours?

Do you have some better profiler than VC Profiler, like DevPartner? Could you run the sample under that profiler and see where is a problem?
 
Also try to send a screenshot there.
