• excelthoughts Conversion of Double to Single

  I've been fighting with this problem for the past couple days and finally narrowed the problem down to the following couple problems: (This is all in VS 2003 .NET 1.1) #1 I have a Generic procedure that has a ByVal parameter of a Single datatype. In one of my modules, I happen to be calling the procedure passing in a Double datatype variable that has a value of 152347.04. When I step into the procedure, the Single datatype parameter then has a value of 152347.047. I've tried type casting the Double to the Single datatype but still get the same results. I can't figure out why it's not converting over the Double to a Single type by adding some erroneous value to it. #2 Also in the same procedure, I was passing in an ArrayList object that was ...Show All

• enric vives Detemining the "owner" of a ContextMenuStrip

  I'm working on a project that utilizes a TableLayoutPanel containing many controls. The controls can be one of three types, and each type has an associated ContextMenuStrip. I have it working where the ContextMenuStrip is applied to it's respective controls within the TLP, and can show and select items from the CMS, but need to be able to determine specifically what control was was right-clicked to show the CMS or the Point of that right click. Thanks for any help! That would work if every control had a unique ContextMenuStrip, however, it's each *type* of control that has one. If I have 20 controls of each type on the TableLayoutPanel then it will execute code against all 20 controls, where I only want ...Show All

Probably best to either put it outside the entire If block, or else use one for each of the conditions. If I could make a suggestion, this isn't really a situation where error-checking via exception handling is advisable. I think it would be much cleaner to just check the contents of the textboxes before using them ...Show All

• ScaryKidsScaringKids VisualBasic.Collection vs VBA.Collection

  Hi. I have ported a good chunk of my project from VB6 to VB2005. There is a VB6 COM DLL that I will not be porting over any time soon. I have a custom list class with an Add method that accepts a Collection (of strings). The list class can accept data from the COM DLL as well as Collections created within the project. Example; Dim Col as Collection Set Col = New Collection Col.Add("String1") Col.Add("String2") Call MyList.Add(Col) As well; Dim Col as Collection Set Col = DBEngine.GetListFromDatabase '//Where DBEngine is the COM DLL Call MyList.Add(Col) The problem though, is that now, under VB2k5, COM DLL's return a VBA.Collection Type, and the normal collection type is VisualBa ...Show All
