hi all,
i installed Switch sample into my WMB environment successfully. And now i add some fields to the switch node attributes, but i don't know how to set attributes in C code.
I have read through the whole WMB information center and searched the current forum, but still there is no usefull info.
Could anybody tell me how?

For the C user defined node sample, called "NumCompute", the C libraries for the NumCompute node are stored in subfolders according to platform. To export the NumComputeNode.lil file into a temporary directory, click File > Export > General > File system, click Next. The UDESampleCCode directory contains the source code for the NumCompute node. Follow the tutorial to discover the needed steps.

hi lancelotlinc,
thanks for your reply. but i really want to know how to set attributes for a C userdefined node in C code.
For example:
if i add some fields to the node attributes when creating the user interface representation of a user defined node in the workbench, how can i set attributes in C code for this node?
i looked through the NumComputeNode.c file, the _NumCompute_createNodeContext() function, there is no other fields setting except "nodeTraceSetting" & "nodeTraceOutfile".
insAttrTblEntry()??_setAttribute()??
please help me.

| Congratulations. Looks like you have done it. |
should not i add some code to _NumCompute_createNodeContext() function in NumComputeNode.c file???
just like
| Code: |
/* Create attributes and set default values */
{
const CciChar* ucsAttr = CciString("nodeTraceSetting", BIP_DEF_COMP_CCSID) ;
insAttrTblEntry(p, (CciChar*)ucsAttr, CNI_TYPE_INTEGER);
_setAttribute(p, (CciChar*)ucsAttr, (CciChar*)constZero);
free((void *)ucsAttr) ;
}
{
const CciChar* ucsAttr = CciString("nodeTraceOutfile", BIP_DEF_COMP_CCSID) ;
insAttrTblEntry(p, (CciChar*)ucsAttr, CNI_TYPE_STRING);
_setAttribute(p, (CciChar*)ucsAttr, (CciChar*)constSwitchTraceLocation);
free((void *)ucsAttr) ;
} |
Otherwise, how does WMB runtime environment know what attributes have been added?? |
