Can't select RGB in Channels
Please help.
Using CS 5 - up until yesterday was able to select RGB in Channels panel separately.
Today when I go into channels I can select Blue, Green or Red separately, but when I go to select RGB on it's own, it won't - it highlights that and the three seperate channels. I can turn the 'eye' icon on and off all of the others but not RGB.
Have I locked this somehow?
Thanks in advance.

As far as I've noticed, that's the way it always works.

Can't select pixels in channels
I'm currently using photoshop cs2 and I can't seem to get it to select the pixels in my Channels. I used to be able to do this,don't know what's going on.Any ideas,maybe a setting got changed ?
What operating system are you using?
You can Ctrl or Command click on any of the channel thumbnails in the channels palette to load a selection of that channel
Or use the keyboard shortcuts shown to the right of the channel names. -
How can I select a channel on the RT target with a VI on the host?
Maybe I'm trying to pound a square peg into a round hole, so please let me know if I'm abusing LV, but ...
I'm trying to parameterize our RT VI app that deals with digital output channels. We use the same basic VI for multiple configurations. The only thing that changes is the channel allocations. So for instance, actuator 1 is on port0/line5 for one configuration and port1/line2 in another. I really don't like the idea of modifying the VI every time we have a new configuration because it makes configuration management insane. If I make a change to the basic VI, now I have to upate N copies of the VI and hope I catch everything.
So I'm making the main app VI read an XML configuration file that specifies all the allocations. Sounds great at first, but how do I create the XML file? I created a VI that manages the data in the VI, allowing the user to add/remove channels and edit the name and channel and then save it to an XML file. The configuration is comopsed of an array of clusters, with the cluster containing the name and DAQmx channel. My intent was to let the user select the channel from the list of valid channels by using the DAQmx Global Channel control. But the problem is, the configure VI runs on the host, which doesn't see any of the channels because they are on the RT target. But if I try to run the configure VI on the target, it refuses to deploy because I have GUI widgets.
Is my approach fundamentally flawed? Is there a better way of parameterizing our VI? Or is there a trick to getting access to the valid channels on the host VI? The information MUST be available because after all, when I modify a target VI and select a global channel constant, I'm doing this on the host.
Thanks,
Keith.Hi Keith,
you can handle the channels like "normal" strings. See the attached picture.
Hope it helps.

I can't seem to get GarageBand to recognize my Behringer X1222 USB Mixer. It will record, but only on the generic "USB Input, without seeing or letting me select the input channel from the mixer. Can't find any drivers from Behringer. How do I getGB to "see" the mixer? Thanks, I'm a newbie to Macs in genreal, and recording...

the x1222 includes a 2 channel audio interface, 2 channels are all you can get from it.
the most you can do is record to 2 tracks at a time; skim this tute to see how:

I can't select the B&W adjustment layer option
When I click on the adjustment layer button in the layers palette, I can't select the B&W adjustment layer option nor the Vibrance, Exposure, or Channel Mixer options. I am using CS5 (just upgraded recently) in Windows. I am not sure why I can't select them (the text appears in light grey and isn't available for selection). Thank you!
Thank you Chris - it was in LAB mode and i changed it RGB and all is well. I hope i marked your answer correctly.

Automation plugin: how to select a spot channel when 2 channels have the same name?
I have a CMYK document opened in photoshop. In "CHANNELS" panel, I just added 2 spot colors with the same name "Sport Color 1".
As I click any of the spot channel to select it, the "Listener" plugin will output some c++ code like below:
SPErr PlayeventSelect(/*your parameters go here*/void)
PIActionDescriptor result = NULL;
DescriptorTypeID runtimeKeyID;
DescriptorTypeID runtimeTypeID;
DescriptorTypeID runtimeObjID;
DescriptorTypeID runtimeEnumID;
DescriptorTypeID runtimeClassID;
DescriptorTypeID runtimePropID;
DescriptorTypeID runtimeUnitID;
SPErr error = kSPNoError;
// Move this to the top of the routine!
PIActionDescriptor desc0000000000003980 = NULL;
error = sPSActionDescriptor->Make(&desc0000000000003980);
if (error) goto returnError;
// Move this to the top of the routine!
PIActionReference ref0000000000001A48 = NULL;
error = sPSActionReference->Make(&ref0000000000001A48);
if (error) goto returnError;
error = sPSActionReference->PutName(ref0000000000001A48, classChannel, "Spot Color 1");
if (error) goto returnError;
error = sPSActionDescriptor->PutReference(desc0000000000003980, keyNull, ref0000000000001A48);
if (error) goto returnError;
error = sPSActionControl->Play(&result, eventSelect, desc0000000000003980, plugInDialogSilent);
if (error) goto returnError;
returnError:
if (result != NULL) sPSActionDescriptor->Free(result);
if (desc0000000000003980 != NULL) sPSActionDescriptor->Free(desc0000000000003980);
if (ref0000000000001A48 != NULL) sPSActionReference->Free(ref0000000000001A48);
return error;
You can see "PutName" add the channel name "Spot Color 1" to reference, and I think it will not work correctly if I add such code to my project since PS cannot differentiate the 2 channels only by name. Can anyone tell me if there's any other method for selecting spot channel? Thanks in advance.Hi
Here is the something from docs tht you may find usefull.
Tryusing index instead of name:
SPAPI OSErr(*
PutIndex )(PIActionReference ref, DescriptorClassIDdesiredClass, uint32 value)
Puts an index into a reference (formIndex) along with the desired class for the reference.
Unfortunately I dont have C++ here to try i just used definition from docs.
Hope that this help.

How can I see the alpha channel in the channels palette?
Hello, mi format plugin loads a rgba image. I see it with transparency, that's ok, but when I go to the channels tab I only see 4 items (RGB, Red, Green and Blue).
How can I see the alpha channel of my file in the channel tab?
Thanks!OK, something must be wrong... but I don't find it!
That's my whole code (resumed). I ommit some code (saving file code (not used) or main function, where I only call te "DoSomething" functions. You can see that I use layers. The DoReadContinue function is only used to show the preview.
In the DoReadStart function I set the parameters for the layers (and the preview), and I fill the "data" and "layerName" params in the DoReadLayerContinue function. I hope you can understand the code!

And that's the image that I obtain loading a 8 layer image:
The layers have transparency (when I set "transparencyPlane" to -1, or 0, or 1, or 2, or 3, or 4....., I got the same result!). The blending mode is still "normal". I had set it to "linear dodge" The "isVisible" param works OK.
Alpha 1 is still black.
Is possible that I need to set something in the .r file? I had to add "FormatLayerSupport { doesSupportFormatLayers }," to manage layers, for instance. -

Selecting SCXI-1122 channels in the Test Panels
All 16 SCXI-1122 channels are multiplexed to channel 0. Is there a way in the Test Panels in MAX to select a specific channel of a SCXI-1122 card in SCXI-1000 chassis so that voltage appears in the test panel?
Message Edited by paryani on 08-25-2007 02:52 PMParyani,
Look at the attached screenshot. It shows where in the test panel you can select an individual channel and see the voltage.

Can not select from data dictionary view from a procedure

thanks for any hint, Lao DeHi,
thanks for that reply, after doing that I can not select this DD-view from sql-prompt anymore (which I don't wonder ;-). Can you tell me, what idea you had behind that test ?
I found another instance, where the procedure works and I will compare those privileges, but it's hard to sort out that complex structure of nested roles and sys_privs.
How ever, I will update here, when I found the missing privilege.

Can't select anything in design mode
I am new on a large Flex project, and when I go into design mode on one of the mxml files, I can't select anything. The other views work fine. Is there a lock, or something? Below is what it looks like (black mark just hides brand info). Note that there is a red line near the bottom. It is actually selectable, but it doesn't do anything. If I go to Source mode and select a chunk of code, then back to design mode, it does show it as selected.
This in Flex Builder 3, thanks.Have you tried using the outline view for selection?

Can not select TV speakers when connected via HDMI
I have a MBP fully updated connected to a Sony TV vis HDMI/miniport. Up until today this configuration was working fine. Suddenly, I can no longer select the HDMI speakers in my audio preferences. They are recognized and appear on the list but when I select them it has no effect. Before today, when the TV was connected the HDMI output would be automatically selected and I could not access the volume control from the menu bar, which is the way I prefer it.
I have restarted with no success in changing this behaviour. If I open/close the lid, the sound goes to the proper settings for about 2s but then the HDMI speakers are de-selected and the built-in speakers are highlighted. I can manually select the TV speakers but the setting has no effect.
However, I *am* getting audio output through the TV but can not control volume from the mac or any app. I slide the volume slider on the menu bar and the audio output does not change. The sound is also playing from the laptop speakers which is highly annoying.and now there is no audio through the TV at all. TV works fine with other inputs such as PS3. Any help?

Can not select 'Show HD' in Finder Preferences
Just performed Data Migration on a new iMac Intel late 2011 from a 2 year old iMac Intel. For some reason, the Macintosh HD does not display on the desktop. If I go to Finder Preferences I can not select Hard Disks. The box is not selected, but If I try to click it, it will not stick. How do I fix that. Not much on the internet concering this peculiarity.
OK, try a couple of things. First is to do some resets, the first I'd recommend doing is restarting the computer in Safe Mode, this will clear some caches. It's possible one is corrupt. Next is to reset the SMC and PRAM, each of these should be done 2x to ensure they work. Finally if that doesn't do it open Disk Utility (Applications - Utilities - Disk Utility) and Repair Disk Permissions 2x.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys. -
