error when create strategy

[draime]

Hi.

Sorry for my first post here beeing some error report.

I am having a problem with Condition builder. I wanted to play a bit with cerating a new strategy (using wizard), and when i select various conditions, like Price > High, or Open, or Close and some others i get an Undandled exception error (Object reference not set to an instance of an object) and ask me to continue or quit.

If i select to continue the Bars ago and Offeset values are grey, and can not be edited. However, other conditions seems to be ok.

I am using using Vista and they have build in .NET.

Hope you can help, i think your software is very cool and would like to play a bit with strategies.

There are some details of the error below, same as i see it when i click that details box. I paste it below. Is just a part of it, as full is more then forum allow to post.

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

This looks like a .NET runtime issue. Please make sure you have installed latest .NET 2.0 runtime from here: http://www.microsoft.com/downloads/d...displaylang=en

Worst case you would need to go through a uninstall/reinstall from link above.

[draime]

thanks for reply.

I tried to before, but it say that the product (.net 2.0) is already installed as part of the operating system.

Should i try uninstall the actual .net?

[NinjaTrader_Dierk]

>> Should i try uninstall the actual .net?
correct

[draime]

No help unfortunately.

I uninstalled the .net 3.2 that was showing in my control panel as beeing installed, but if i try to install net 2.0 it still tells me that is already instaleld as part of operating system.

[NinjaTrader_Dierk]

Please try to uninstall .NET 2.0.

[draime]

i would love to but i can't seems to find it. It does not show as a program in add/remove programs. It is like is already build in somehow, and nt visible to user.

[NinjaTrader_Dierk]

Hmm ... this is 32 bit Vista and not 64 bit Vista no?

[draime]

Hmm ... this is 32 bit Vista and not 64 bit Vista no?

Is 32, nothing really fancy. Vista Home Premium, 6.0.6000 Build 6000

Came already installed on the laptop (i wish i had a choice)

[NinjaTrader_Dierk]

Ok .. let's try something different. Please provide exact (!) steps on how you reproduce the issue so we could research.

[draime]

Open ninjatrader.

Tools> New Ninja Script > Strategy

On the wizard just click Next till see the Conditions and Actions window.

Click Add for Set1, click on price data and then click on Open or Close

At that exact moment i get the error window

I am not sure you will have same problem, unless you have same Vista.. i have to say i hate it

[NinjaTrader_Dierk]

Ok, let's try this:
a) we are about the release a new NT6R7 (within the next few days). Please let us know if issue will persist with that release.
b) we will test this new NT6R7 on our Vista machines here

[NinjaTrader_Dierk]

Another one: Please make sure you have installed latest Windows .NET updates.

[draime]

i have all updates windows prompt me to install.

on the other hand, i tried with ninjatrader 6.5 beta too. The error still persist, just that is another kind of message.

[NinjaTrader_Dierk]

What message do you get there?
