在ShowModal的窗体里如何走流程**

alang

18楼有错误，showmodal的窗体可以流转和回退的

Coordinator

恩 那个问题解决了
可是还有问题 那段代码是启动流程 我双击待办任务还是执行的启动流程阿 无法继续往下走啊

alang

22楼，我糊涂了
19楼问题到底是解决了还是没有呢？

Coordinator

不好意思啊 19楼问题解决了

可是还有一些新的问题
1，流程结束了 那个代码
lFlowControl.StartupFlow(lBizURL, ProcFunc, lExecutor, lFlowValue);
中的 “ProcFunc”应该赋什么值
2，在待办任务里的任务是递增的 不像别的流程那样新的任务替换原来的任务

1，流程结束了 那个代码
lFlowControl.StartupFlow(lBizURL, ProcFunc, lExecutor, lFlowValue);
中的 “ProcFunc”应该赋什么值
这里是流程环节的ID

alang

2，在待办任务里的任务是递增的 不像别的流程那样新的任务替换原来的任务
没有理解

Coordinator

lFlowControl.StartupFlow(lBizURL, ProcFunc, lExecutor, lFlowValue);
中的 “ProcFunc”应该赋什么值
在不是最后一步的时候 赋的 FlowBroker1.FlowControl.CurrentProcUnit.SuccedentUnits[0].ID 是下一流程的id
在最后一步的时候也用这个嘛？

alang

难道你每一个环节都是用Startupflow来“流转”的？

alang

流转，请使用flowout，不要用StartupFlow
startupflow是启动一个新的流程实例，不是流转当前流程实例，我在15楼就说过了
