DesiredColor and Seamless mode

[mlowe9]

Can I control the "DesiredColor" setting of a seamless citrix session?

I am using a simple .ica file with the Citrix MetaFrame Presentation Server plugin. Doesn't seem to matter what setting I use in my .ica file (I have "DesiredColor=8"), it never seems to work.

I have an application that requires "TrueColor", and it gives me an error when trying to run it in seamless. Is there a setting on the server I can set?

Thanks.

When you publish the app you can set the desired colour. You should be able to set it at True Colour, depends on what version you are running tho.

I have tried that, but when I run the app seamless I still get the "you're not in True Color" message.

It's possible that the application is not looking at the session color depth. Does this work when not in seamless mode?

I assume that the client is actually displaying 24 bit color, yes?

It does work when not in seamless mode, and the client is in 24 bit color.

What if you are not in seamless mode and @ 24 bit color, i.e. if running a full-screen ICA Session, or if it's Server 2003 a 24 bit RDP Session?

The only time it doesn't work is in seamless mode, but I want it in seamless mode.

We are on Windows 2000, MetaFrame XP. We are a large organization, so we cannot just upgrade the server and Citrix version - it's more complicated than that.

I really need to make this work on our Windows and Citrix versions, and in seamless mode. How can it not run seamless in 24-bit color? It seems so simple...

 

[patrickrouse]

I wan't suggesting that you switch permanently, just that you use other client display options to narrow down your problem.

So it works fine if running full-screen or in a window. What ICA Client Version are you using, and have you tried other builds?

Have you talked to the software manufacturer about the problem?

Does it work in RDP connection to the application, you can specify a connection to an initial program.

Scott,

Could you elaborate? I'm not sure what you mean. Please keep in mind I have limited Citrix knowledge - I'm more of a web-programmer who has done some .ica file stuff... Plus we don't use NFuse - just the Presentation Server plugin to do our web citrix connections...

Thank you both for your help - I would really like to get this working correctly, I have deadlines coming up soon...

 

[ascotta]

No worries. If you use the RDP client (mstsc.exe) you can make a connection to one of the servers and specify an exe to run instead of a desktop(explorer). You will have to set the res etc as high as you can though. In fact I think you can do that from the citrix cilent too by using custom ICA connections too.

Thanks for the suggestion.

All we've ever done web-wise is make sure the client has installed the plugin (ica32t.exe), and put a link to the ica file on the web page. It works great (most of the time), and I don't have time to rethink everything I'm doing.

It's just this one dang application - maybe we'll just have to deal with it - but I still don't understand why the color depth doesn't work running seamless.

You guys rock!

No one is suggesting that you scrap your current deployment methods, we're just trying to see what works, and what doesn't. What is the application, and are you the developer? If you are not the developer, who is?

The application is MagicWeb, it is a Siemens product for Radiology departments - it displays X-rays, etc so the True Color thing is important for this application, because X-rays obvioiusly need to be detailed...

 

[patrickrouse]

So is it a DICOM Viewer? I would check with Siemens as far as compatibility with Citrix' Seamless Application, as there might not be anything you can do if the application expects a certain operating environment.

Before you talk to them, I'd check the following situations:

1. Does it work in full-screen or windowed mode in the RDP Client.
2. Does it work full-screen or windowed mode in the RDP Client with this application specified as the startup program (in the RDP Client Settings)
3. Does it work in full-screen or Windowed mode in the Full Program Neighborhood ICA Client (which version?)
4. Are you using the latest ICA Client, i.e. 9.x.

Ok, here's what I've found.

1&2) I seem to get the same problem on all counts of RDP.
3) I do not have the Full Program Neighborhood on my PC, but if I
4) We are using version 8, but I tried 9 just now and it doesn't help.

I said this earlier, but we're kindof back on the subject. If I set my .ica file to not seamless (TWIMode=Off) with my desiredColor=8, then it's ok.
