• QuinceArj Desktop and Start Menu Icon?

  How do I have the Windows installer / setup in VS 2005 place an application icon on the desktop and start menu when the installer installs the application and support files. Nothing in the property pages, and can't find documentation. Unfortunately that sort of operation at install time is not supported in ClickOnce. Later perhaps... but until then you are likely stuck with going without or making your own at runtime and that wouldn’t get removed when the app is uninstalled. In the mean time I'd suggest taking a look at this thread where this was discussed in length and maybe even stopping by the Visual Studio Connect page and telling them about your need/like for it. The File System view in ...Show All

• Matt Lin Seeking sample code for DataGridView

  All, I am quite familiar with ASP.NET but am struggling with WindowForms.NET. I am hoping you can help. The application is very simple: I have a database with two tables that are related: TABLE 1 - tbl1_ID tbl1_col1 tbl1_col2 tbl1_tbl2_ID TABLE 2 - tbl2_ID tbl2_col1 What I would like to do is to display a DataGrid with the following columns: tbl1_col1 | tbl1_col2 | tbl2_col1 where tbl2_col1 is in a ComboBox column. The user should be able to edit any row and add new rows. If a new value is typed into the ComboBox, this should create a new row in TABLE 2. I know exactly how to do this under ASP.NET 2.0, but am really struggling with WindowForms. Would you please point me to an e ...Show All

  I get the error below when I call many of the HTML... components, such as mshtml.HTMLAnchorElementClass or mshtml.HTMLDivElementClass. for example: foreach (mshtml.HTMLAnchorElementClass aAnch in aItems) When I do that the program dies immediately. and this error below is posted: Unable to cast COM object of type 'System.__ComObject' to class type 'mshtml.HTMLAnchorElementClass'.

• Snickel65 moving rows in datagriview

  Is there a way to move a row in a datagridview up or down Thanks. This text will give you an answer How about something along these lines (the first row becomes the second row .. just be careful to ensure your row remains in bounds) Dim view As DataGridView, row As DataGridViewRow = view.Rows.Item(0) view.Rows.Remove(row) : view.Rows.Insert(1, row) Hope this is what you were looking for Richard Jim... all that code does is remove the selected row. if u r binding the grid to a table in database simply keep a colum in the table of priority and give all the rows a priority when displaying the data in the grid keep that column hidden keep the selectio ...Show All

• kawing0510 Filtering a datagrid view

  I have two datagridviews (A & B)filled by 2 different datasets and I want to filter datagridview B based on cell X on the current row of the datagridview, any sugestions on how I can do this I read through the documentation and the properties of the datagrid but nothing poped out at me as the correct property..... Jankowiak It's a difficult question to answer directly with such limited information but have you tried looking at DataViews i.e. DefaultView is a property of a DataTable and you can set the RowFilter property which is a psudo-sql expression as a string. From this view you could then utilise the ToTable() method and bind that to a control. Any help you co ...Show All

• Karthick1020 Highlighting Visible without Focus -Find Control

  I am reinventing the wheel with a find box. How do you get the highlighting to remain visible when the focus isn't on the parent form I watched what happens when I use VS's find box. The parent form momentarily gains focus, then switches back to the find box. What needs to happen in order to keep the highlighting visible when the focus reverts to the find form Guessing: you click the Find button so now the focus is on the button, not on the control that contains the search text. It depends on what control you use to display the search text. If it is a TextBox, set the HideSelection property to false, SelectionStart to 0 and SelectionLength to Text.Length. I don't catch your meaning very c ...Show All
