In order to omit the byte order mark (BOM), your stream must use an instance of UTF8Encoding other than System.Text.Encoding.UTF8 (which is configured to generate a BOM). There are two easy ways to do this: 1. Explicitly specifying a suitable encoding: Call the UTF8Encoding constructor with False for the encoderShouldEmitUTF8Identifier parameter. Pass the UTF8Encoding instance … Read more
Set is assigning a new reference to the AST variable, rather than assigning a value to (the object currently referenced by AST)’s default property. There’s not much VB 6 documentation around on the web, but1 some of the help for VB.Net still references the older ways. See Default Property Changed for Visual Basic 6 Users: … Read more
There is no way to declare global variables as you’re probably imagining them in VB.NET. What you can do (as some of the other answers have suggested) is declare everything that you want to treat as a global variable as static variables instead within one particular class: Public Class GlobalVariables Public Shared UserName As String … Read more
The only short circuiting (of a sort) is within Case expression evaluation, so the following ungainly statement does what I think you’re asking; Select Case True Case (myObject Is Nothing), Not myObject.test() MsgBox “no instance or test == false” Case Else MsgBox “got instance & test == true” End Select End Sub
The first thing to note is VB.NET does not have a direct analog to C#’s (type)instance casting mechanism. I bring this up because it’s useful as a starting point and common reference in comparing the two VB.NET operators (and they are operators, not functions, even though they have function semantics). DirectCast() is more strict than … Read more
most problem cases are solved by translation vectors intersection check black is the original line/curve whatever … gray is translation vector (normal to black and size = outline distance) blue is outline if the translation vectors not intersect then it is most likely all OK but if they do then just do something like this: … Read more
You did not indicate which DB provider you were using, but the standard provider (from the SQLite devs) will see Integer and map the data to the NET Int32 type which doesn’t allow decimals. Real would save fractionals as would Decimal. there is no other type in SQLite. there is only “Text”, “Integer”, “Real” and … Read more
It has probably got to do with that the WebBrowser control by default uses a document emulation mode of IE 7, meaning all pages are handled using the Internet Explorer 7 engine. Since that version is quite old most websites today are not compatible with it, which affects the functionality when you visit the page. … Read more
