• Visual C++ converting c++ stl strings --> Tchars? (NO MFC)

  How would I go about doing this Thanks! I ran into string problems all the time in unmanaged c++. You can use the cstring() method of a string class to get the c style string and then use the multibytetowidechar() function to put that c string into a tchar buffer. Its a big pain and maybe not efficient but it works if speed isnt of vital importance to you. I made a function to do it because I had to do it so many times. Granted my data was not thought out well at all. ...Show All

• Software Development for Windows Vista refactored TimerService sample?

• SQL Server Selecting Connection in Custom Destination Component UI

  Hi there, I am writing a Custom Destination component with a custom UI. The UI contains a combo box which contains the connection names of type “FLATFILE”. I also have provided a button which would create a new connection of type “FLATFILE” by making a call to CreateConnection method of IDtsConnectionService. The combo box gets properly updated showing the connections of type “FLATFILE” but on clicking on the new Connection button the application hangs up. Am I missing something or is there some other way to do it The function are the events handlers which are called by the UI. void form_GetC ...Show All

• Windows Forms listbox issues

  I've had a problem with listboxes not firing the SelectedIndexChanged event. I tracked this back to what appears to be a bug in the ListBox class, where the Clear operation simply does not fire the event, although Remove/RemoveAt do. Is there any chance for a fix for this in the near future. I can provide details on this if necessary. Thanks This is probably by design, but I would agree, for the sake of consistency the event should be raised. As a workaround, you could call the ListBox method ClearSelected before calling  Items.Clear . This is not perfect though because in your SelectedIndexCha ...Show All

• Visual Studio Express Editions Updating the database

  I am asking a pretty common question it seems. Yes, I did look and do see the existing posts/responses. My problem is that I am not seeing the database actually get updated with new data. It seems fine at runtime, but if I shutdown the app and check the Db it is not getting back to the table. I also added some code from one of those VB for dummies books to help check that the update worked and it claims it is. I must be a different kind of dummy, lol. As I mentioned, I have seen the numerous responses regarding this issue, so I am quite puzzled as to why this isn't fising my problem. I checked the "copy to output di ...Show All

• Software Development for Windows Vista Changing Dependency Properties from Code

  Hi guys, as I'm getting always the right answers here - I have another "simple" one. When I change a dependency property of an activity in code the WorkflowDesigner is not persisting it because it does not "realise" that the prop has changed. No matter if I do it directly like activityinstance.Property = "string"; or through activityinstance.SetValue(Activity.PropertyProperty, "string"); This is different if I change the settings through the UI using the Properties pane. Question is - what function or property will cause the WorkflowDesigner to persist the workflow definitions ...Show All
