• SQL Server Attachement generated by xp_sendmail

  Hello folks, I am sending a email from sql server that consists of results of a query and that's working perfect. When I open the text file generated by xp_sendmail in notepad it's OK, but when I open it in MS Word or WordPad, I see garbage characters in form of squares added to the content. Those sqare are unicode spaces equivalent to Nchar(140) or Nchar(0020) in SQL. I tried to replace them using the replace function : declare @foo varchar(8000) set @foo='select top 4 Replace(priMarykey,Nchar(0020),'') as primarykey, Replace(Sitename,Nchar(0020),'') as Sitename, Replace(REgNumber,Nchar(0020),'') as REgNumber, Replace(ContactEmpFirstNames, ...Show All

• Visual Basic Cint method problem

  hi, note even and odd number get different result . Cint(2.5) = 2 Cint(3.5) = 4 Cint(4.5) = 4 Cint(5.5) = 6 ........ why this happen CInt is documented as using Bankers Rounding : Fractional Parts. When you convert a nonintegral value to an integral type, the integer conversion functions ( CByte , CInt , CLng , CSByte , CShort , CUInt , CULng , and CUShort ) remove the fractional part and round the value to the closest integer. If the fractional part is exactly 0.5, the integer conversion functions round it to the nearest even integer. For example, 0.5 rounds to 0, and 1.5 and 2.5 both round to 2. This is ...Show All

• Visual Studio Tools for Office Excel Data Binding Performance

  I just updated my Excel VSTO code to use data binding (via ListObject) to a DataSet. Prior to this, I was putting data into a 2-dimensional array and setting it to a range. Now the screen update is significantly slower. We often times will have large DataSets. In one example, I had a DataSet with 10,000 rows, and 20 columns (with floating point data). With data binding, it took close to 1.5 minutes (90 seconds) for the screen to refresh. When I set the range directly with a 2-dimensional array, it took less than 5 seconds. While I fully expect it to take longer with data binding, I really didn't expect it to be that much worse. Am I force ...Show All
