Hi hink,

LabVIEW can create the GUI shown (LV 8 intoduced splitter bars), however dynamic splitter bars are a problem. I can think of several solutions:

• Picture control, in that case you draw every pixel yourself
  
• seperate windows, each control has it's own window, that you move around from some controller VI

The simple answer is NO. You cannot dynamically create splitter bars if none exist. You can, however, operate on them programmatically after they've been created. Right-click on a splitter and select Create>Property.

Generating objects programmatically is a feature that is called scripting. This is a hidden feature

that can be enabled by a special LabVIEW.ini entry (reserved only for NI).

In LabVIEW 7.1.1 this feature can be made visible by adding the keyword "SuperPrivateScriptingFeatureVisible=True" in the LabVIEW.ini.

Have a look into the "rusty nails" -> "scripting" topic in this forum.

Unfortunately this keyword does not work any more. NI has changed this in LabVIEW 8.0

my problem is continue ,

the menthod i found now is make enouge splitter bar, and show /hide them in the programe.

but the effect is not very good

Show us what you've done - maybe we could make suggestions on how to make it look better.

This can be done by using subpanels to subpanel VIs containing one splitter bar and two subpanels to create arbitrary splitter bars (recursively). However, this technique tends to crash LabVIEW.

WARNING: These examples will crash LabVIEW.

While this is all correct there is one extra caveat. You can not use scripting for changing VIs that are non idle. This means to do what the OP would want you would have to write a different VI that loads the VI to modify into memory, modifies it and only after all modifications are done, does start it. And whenever you want to change it again the VI needs to be stopped, modified and restarted. Basically not something I would ever consider to do.
