• Windows Forms Framework and Windows Installer not present

  I am deploying a project on a large number of user machines. On a W2K machine, when I tested the MSI, it of course, did not have the Framework or the correct version of Windows Installer. But I did get the expected error messages. So I am going to issue install instructions that state the order of install is to first install these two items, and then install the application. Do any of you do anything different Lacking resplies from anyone else, maybe I'm asking the wrong question. Sometimes there are bugs that everyone knows about, except me. Perhaps the right question is... Does this feature work for anyone at all If I don't hear from any more people, that this works for ...Show All

• Software Development for Windows Vista overload methods in WF

  Hi all, i would like to know how can methods(activity) be overloaded in WF. For example i have a if-else activity, a sendMail() method. If the ToName is XXX then doSomthing() and then sendMail(XXX), else if ToName is YYY then doSomthing() and then sendMail(YYY). How can the parameter be handed over Should i use a queue for the parameter (or Dependence Property) But how can i choose at runtime the right parameter Thanks Emy_P, Just so I can understand what you have here, let me take a shot at describing what you have based on your description... You have created a custom If/Else activity: Is this derived from CompositeActivity or is this a SequentialActivity and you've dropped a base class If/Else ...Show All

• Software Development for Windows Vista Is this doable? How? Thanks

  Let's say we're in a workflow that we designed in VS2005 and half way through the workflow we have a group of activities that we want to execute in parallel. At design time, we don't know how many parallel runs we'll have nor do we know the actual parameter values that will be passed into each parallel run. So, we have an activity that return an array of parameters and we want to run the next few activities as a group. We want to run them in parallel and each of them need to use one of the parameters in the array. Does this make any sense and what would be a best practice Also, is it possible to run these activities on multiple hosts to lessen the processing burden Thanks CostasZ Jon, tha ...Show All

• SQL Server Optins of trailing Database change in sql server

  Hi All, I am in need of some option using which i can trail the changes made to my database. Specially i want to track all the DDL and DMl changes. I know about the external tools provided by lumigent and some other companies to do this but i was just wondering if we have some option within sql server. I don't need extensive report as provided by lumigent. Just getting somethin on DDL and DML will help.  Even help on some work arounds to do same will be appreciated. TIA Prashant   If you don’t want to read from the log, you will have to implement something on your own, like putting triggers on every object for tracing DML and DDL. The best thing to keep track of all changes made to the data ...Show All

• Smart Device Development USB Port

  Please suggest me how can I write applications for USB and Irda drivers. How can I open the USB/Irda ports, and read/write to/from the ports. Hi, I am not absolutely sure, but I suppose that if you keep open all time USB/irda/wifi/bluetooth connections, it would lead you to batery power disaster. Nonetheless, do not mix usb interface with bluetooth or wifi, for example. They are different types of interfaces that use different adapters for communication. Only general thing is that all radiomodems can be accessed through COM ports. According to ActiveSync, in RAPI has enum RAPI_CONNECTIONTYPE defined like this: typedef enum { RAPI_CONNECTION_USB = 0 RAPI_CONNECTION_IR ...Show All
