• brohans Dynamic User Interface

  Hi, I'm starting to work a new windows forms application (.net 2.0), the problem is that the Interface needs to built dynamically. I have no idea how to achive this, can anyone recommend an approach My first, and only, idea is to use an XML file with one element representing a single control However I'm unsure how efficient this is. Any help would be much appreciated. Mark Hello All. Mark: No, I can't say that I've run across anything, but that's not to say that there isn't anything out there, as I haven't really been looking. Sorry. As I say, from what I understand, WPF uses XML as a basis for the UI elements, so you might want to get the .NET 3.0 SDK and look through the WPF and se ...Show All

• Jkumar Suppress Script Error in WebBrowser control

  Hi, I use a WebBrowser control to navigate to a html page which contains JavaScript. When I open this page in the IE browser no JavaScript error is shown and the page is displayed and functions perfectly. But when navigating to the same page with the WebBrowser control, a pop-up appears to inform about a Script error. I have tried to suppress the script error with the ScriptErrorsSuppressed property but now another pop-up comes up with the title "Visual Studio Just-In-Time Debugger" and proposes to debug... Why is the WebBrowser control not behaving like the 'normal' IE browser and how can I suppress these pop-ups Thanks for any hint! Claudia http://support.microsoft.com/kb/279535/ ...Show All

• JeremyAtGosub add 2 DataTables into 1 DataGrid

  hi, I have 2 dataadapters that fills 2 datatables i want to show them both in 1 datagrid How do i do it How do I do it Why not create a new table combined by those two tables I think detail steps to combine two tables depend on the logic how you want to combine them. If you just want to create a new table with all columns in those original two tables, use following code for example DataTable dt = new DataTable(); foreach (DataColumn column in northwindDataSet.Customers.Columns) dt.Columns.Add( new DataColumn(column.ColumnName,column.DataType,column.Expression)); foreach (DataColumn column in northwindDataSet.Employees.Col ...Show All

• JoshKorn How to resize a TextBox to fit the text in it?

  OK, I'm hitting a very unexpected stumbling point here. I've got a series of Textboxes displayed in a TableLayoutPanel. Each of these textboxes shares a row with a button. The button is of fixed width and the TextBox fills the remainder of the row. The behavior I want from the TextBox is to automatically resize itself in the Y-axis if the text in it is multi-line. Right now, I'm automatically resizing the TextBox on the TextChanged event. This works partially. I can get the number of lines of text with a GetLineFromCharIndex call that takes the Index of the last character of text in the TextBox. I then multiply the number of lines by the height of the font, and add the difference between the Bounds.Height and ClientSize.Height to figur ...Show All

I have been getting myself used to working with the the Visual C++ 'designer' and would like to try making a basic web browser with 1 Textbox, 1 Button, and 1 WebBrowser control.
