• Visual Studio Express Editions How to refill a dataset?

  I have this code in my vb.net program. Me.TickersTableAdapter.Fill(Me.DataSet1.Tickers) It fills the data from the external file fine. However, I'd like to be able to refill the data after it has been changed by an external program. Calling the line a second time doesn't work because I get "datareader already active on this command" error. How can I refill the data from the external file tia No worries, I'm blind ! Just found the .Clear command. Hopefully efficient enough. Thanks go to these good folk! ...Show All

• Windows Forms How to control record deletion using BindingNavigator?

  Hello.. When I use BindingNavigator to navigate records shown in a DataGridView a button whose default action is to delete records is placed on the toolbar. How can I show a confirmation message when that button is clicked I tried to use the Click event but when I don't accept the deletion, I don't know how to cancel the process.

Any help will be greatly appreciated Thanks Jaime Firstly you have to select your bindingnavigator - > property . set deleteitem to none. then this code - > Private Sub BindingNavigatorDeleteItem_Click( ByVal sender ...Show All

• Visual Studio 2008 (Pre-release) CompositionTargetRendering vs Timeline animation

  Hi all, From a display point of view, is there a difference between operations performed by an animation timeline, and those done in a CompositionTarget.Rendering event By difference, I mean the smoothness of the animation achieved with the two approaches. In Flash, one notices a difference between animations done in onEnterFrame, vs. actions that are timer based. One can also liken this to the old practice of syncing graphics operations with the vertical retrace interrupt. So, in the WPF context, are animationclocks somehow aligned with render events Thanx for the detailed and helpful reply. Another unknown that I have in the area of timelines and performance, regards the begintime property. When you run a timeline whose begintime ...Show All

• Visual Studio Team System Project/TFS Integration issue - please help

  Ok, this is my last effort before opening a ticket with Microsoft and spending the rest of my life on the phone with them. I have Project Server setup, and I have it receiving its data from TFS. The data is replicating between the 2, etc. Here is the problem. When I click "Refresh" on the Team plugin for project a couple times, the data will change. Here is an example: I have a work item with Actual (Completed) Work set to 8 hours. This shows in TFS. Refreshing it in project shows the 8 hours fine. However, if I refresh again it changes it bakc to 0. Clicking refresh 2 more times sets it back to 8, hitting it again makes it go back. This happens with most of the work items, and I cant for the life of me figure out what it is. ...Show All

• Visual C++ textBox - 2 questions

  Hi all. I have a textBox controler in my win app that i write in c++. I insert data into the textBox in runtime. 2 Questions: 1) Is it possible to insert the data in LIFO that means that if i insert line "bla bla bla" then new line and then "yada yada yada" it will appear as yada yada yada bla bla bla Is it possible without clearing the box each time, writing new line and then filling with old data. (I have a lot of info and after a while the screen updates slow) 2) If the first question is answered and the data is inserted in LIFO, is it possible to show only the last X lines As i mentioned i have a lot of data comming in but only the last data is the relevant to see...

• Visual C++ Legacy MFC app using HWND_TOPMOST

  Hi All... We have a browser-based application that uses an active-X control to spawn off another process. This spawned process is written using MFC. It performs a call to SetWindowPos with HWND_TOPMOST specified - this is so the application will force itself to the top of the Z-Order. And (until now) it works fine... We've found however, that when that that active-X control lives in IE7, the app spawned does not force itself to the top of the Z-order. It gets above all other apps except for the IE7 from which it was spawned. Any ideas as to why IE7 refuses to allow the app to get above its Z-order Hello Curt, Thanks for your advice. Personally, I want to apologize for make you feel frustrated. I agree ...Show All
