• SQL Server How can I assign a value to a textbox programmatically in a report?

  For example: If I want to display the date today, txtDate.Text = DateToday; There is no way other than assigning a expression to the Textbox. The "MS Access way" doesn't work anymore ;( You can do something like: =iif( some_condition = true, System.DateTime.Now, "No Date") or create your own function: Add Public Function myFunction(val as Object) if val is Nothing then return System.DateTime.Now return "Empty" End Funcion to Report-Properties->Code and call it by =Code.myFunction(Fields!ConditionColumn.Value) ...Show All

  We had a working Data Provider coded in C# using VS2003. The same code gives a problem in VS2005 and I'm hoping someone here can help out. Sample code: DataSet ds = new DataSet (); TTDataAdapter da = new TTDataAdapter ( "select name from master..sysdatabaseinfo", m_Conn ); da.Fill( ds, "Table1" ); This will raise an exception when the data provider is compiled in VS2005: [System.ArgumentException] {"Type of value has a mismatch with column typeCouldn't store <master> in name Column.  Expected type is RuntimeType."} I have checked everwhere I could and the name-Column's DataType is "System.String" as it s ...Show All

• Visual Basic Visual basic 2005 Express - DLL/package Question

  Hi all, Apologies if this is in the wrong forum. I'm a first time user of VB Express, having decided to take advantage of the year long MS offer for hobbyists to learn the trade. As such, if I try the patience with questions the are potentially rudimentary to some of you, please bare with me. Here's my concern. A while ago I sent some sourcecode for an application that was written in VB6. These include the .vbw/.vbp and whatnot files. I don't have access to VB6 and have thus tried updating it via the wizard in my Express edition. The only option I've got when doing so is to upgrade the sourcode to an executable. I designate a new destination ...Show All
