I've created a class that manages two threads for reading from the stdout and stderr streams of a child process. The class is working fine now by pausing the threads when they aren't needed by calling Thread.Sleep(Timeout.Infinite), but I have a question about resource usage...
Does it make more sense to allow the threads to finish execution and recreate them when needed or to just sleep them and then wake the threads up via Thread.Interrupt when needed?
I am making a Kiosk system and would like to recreate the Windows Taskbar in VB.NET, specifically the window management features of the taskbar: displaying open windows, switching between windows, and highlighting which window has focus. if the taskbar had the same positioning properties as the Windows Taskbar, in that even when other windows had focus the taskbar would still have focus and would not taking focus away from windows on the screen, and maximized windows would not maximize over the taskbar.
View 1 RepliesI'm playing around with VB.NET once again since college and I'm trying to recreate a program that GeekSquad uses called the MRI for a friend.Upon doing so, I have run into a few snags. The must present one is once I publish my application to a particular spot that also includes already setup folders with portable apps setup in them. I want to use Process.Start("App Path") where App Path is the drive letter of where the Custom Program exe is located and calling file Test1.exe in the test1 folder in the root.

I am using a button on a form which creates a chart at runtime when the user clicks the button. it works ok for the first time but when I select the button the second time I get a square diagonal box or indexoutofrange Exception.Note: I have another button that clears the series from the chart before reselecting the button that creates the chart.

I would like to recreate the behaviour of a button or command button on an user control. I need to layout a group of this user control on a form so user can select only one at a time. When users click on one of this user controls a selection frame is drawn to indicate that it has been selected. The problem I have is clearing the selection frame when other control is clicked on. How do buttons or command buttons do this? If you layout a group of buttons only one is highlighted. I have tried using different events like LostFocus and Leave and nothing seems to work.

View 2 RepliesI refreshed my data sources to include additional items from the SQL Server databases and it appears that my entire data source from my VB.NET project disappeared.I am using Entity Framework. I may have clicked on something wrong, not quite sure. Unfortunately I can't recreate the Data Source without creating a new Entity and Data Model.I can delete the entry in the App.Config file and recreated it, however things aren't quite right.Is there a way that I can recreate my Data Source from the entry that is in my App.Config file...since that appears to have remained intact.BTW, I can go to my Data Model and successfully refresh from there, however my project isn't connecting to the database so I have quite a number of errors until I can get reconnected.
View 4 RepliesAs part of my current project for making student's lives easier by making an All-In-One application with many common programs carbon-copied inside it, I have a slight problem with sticky notes.
I am trying to recreate Sticky Notes as much as possible from the Windows 7 Sticky Notes Application. My problem is, I put a richtextbox on the sticky notes panel and wanted to either add a background image, or a transparent backcolor (my Panel that the textbox is in has the background image of the themed sticky notes). So my question is, is it possible to somehow dynamically make a property to allow the backcolor of a richtextbox to be transparent? or allow a background image?If you find an answer helpful, click the Helpful button.

I have on my form two datagridviews that correspond to the same table. They are both databound. They have been created automatically through dragging them from the datasources windows.One is datagridview and the other datagridview1. When ever I navigate through a datagrid the corresponding row on the other grid changes as well. I do not want this. Also I want to be able to fill and use each datagrid indepentent from each other. To fill a datagridview on load I use this code
Me.AllServicesTableAdapter.workstation(Me.Database2DataSet.AllServices)This code does not let me choose which datagrid to fill.
I have a search form on that will be pulling search template queries from a table in the underlying (an Access db on a share). The search form has a calendar control for filtering by date range, a listbox containing the names of the search templates, a second listbox which lists the fields in the selected template, and then some controls which show/hide themselves depending on which field is selected so that the user can pick a field and enter it's unique criteria in the appropriate control for filtering. Below these controls is a DataGrid, which will obviously display the results.
The problem is how to dynamically "transform" this DataGrid to display the selected search template. These templates do not represent tables in the underlying; rather they represent preconstructed SQL queries (stored in a table) which are essentially SELECT queries with joins and no WHERE clause (so they are the results of multiple tables joined together by their keys).
To be honest, I'm having trouble even generating the LINQ queries to represent these template dynamically, but that's not as important, since I can manually translate the SQL queries into LINQ. This is definitely not the preferred method, as the whole point of putting these templates in a table, rather than code, was to allow for future additions without rebuilding/redistributing the application interface.
what are the differences between the WPF Datagrid included in the .NET Framework 4.0 versus the Datagrid included in the out-of-band WPF Toolkit? I understand that the toolkit version was released first, and targets the .NET Framework 3.5 SP1.
I needed a WPF datagrid quick and have utilized the toolkit version in my applications. I'm considering moving the application to .NET 4.0 and am wondering what the pros/cons will be in changing out my existing datagrids for the new ones.
I have one data grid which contains a column which contains long string values. When I edit it, the text box which appears is very small. I want to increase the length of text box.

I have converted a VB6 app to .NET using VB 2008 Express Edition, as recommended in the VS 2008. Actually just opened VBP project using this software and followed the wizard's instructions. The app has a form containing the ADODC control and AxMSDataGridLib.AxDataGrid. The DataSource property of the Grid is set to ADODC. (Actual data comes into UI from some DLL.)When I start debugging the converted app I immediately receive following error:Error -2147467259: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified.Same error happens when I try to set the ADODC object to the DataGrid.DataSource programmatically (in run time).The VB6 version of same app runs without any problem.
