kennyl	Posted - Apr 06 2011 : 03:06:18 AM When modify code, our company requires us to add some sort of "Code Mark" and have the original code commented out instead of directly remove/modify them. For example, original code: pRetNumber1 = nResult1; // validity checking missed pRetNumber2 = nResult1; // bad Copy & Paste here Updated code: //-- CODE_MARK_BEGIN, date here, author's name here, ... //pRetNumber1 = nResult1; //pRetNumber2 = nResult1; if (pRetNumber1) pRetNumber1 = nResult1; if (pRetNumber2) pRetNumber2 = nResult2; //-- CODE_MARK_END To do this job I will have to: 1. Select the code block. 2. Comment out the original code. 3. Select the code block again. 4. Either press a key or use VA's menu to add "Code Mark" by VA Snippets. 5. Add modified code. So, I wonder if VA could provide a way to comment out things like $selected$ in VA Snippets, like this: //-- CODE_MARK_BEGIN, $DATE$, Kenny {CmtBegin} $selected$ {CmtEnd} //-- CODE_MARK_END {CmtBegin} and {CmtEnd} here are tags to indicate what to be commented out, and also it'd be better if VA could use single line (C++) / multi-line comment (C) base on the number of lines of $selected$. Regards, Kenny

I am not sure about getting the user name in a macro, but you should be able to pick up the current date and time in VBScript using the standard functions. A simple IDE macro to comment out the block using either // or /* / comments, based on the number of lines with text on them is: ' select a block of text then trigger this macro Public Sub TurnSelectionIntoMarkedBlock() Dim objTxtSel As TextSelection = DTE.ActiveDocument.Selection Dim colRanges As TextRanges = objTxtSel.TextRanges Dim objRange As TextRange Dim nTotalLines As Integer = 0 ' the number of selected lines that contain text ' count the number of lines that actually have text in them For Each objRange In colRanges Dim nLineLength As Integer = objRange.EndPoint.AbsoluteCharOffset - objRange.StartPoint.AbsoluteCharOffset If nLineLength > 0 Then nTotalLines = nTotalLines + 1 End If Next If nTotalLines > 1 Then DTE.ExecuteCommand("VAssistX.SelectionBlockComment") Else DTE.ExecuteCommand("VAssistX.SelectionLineComment") End If End Sub since this is using VA to do the commenting, when VA does a block comment, / /, VA will handle any existing / */ comments inside the selected lines as normal. This just leaves you needing to move up and down, add a line, and type any start and end marker comments you want. I hope this helps to get you started.

Just select the code to mark, and tell VA to use a Snippet on the selected code. This can be done via the right click menu or by pressing the VA toolbar button "Insert VA Snippet". The $selected$ code might contain comment, so /...*/ might not work in that case, and second, I'd still prefer VA to decide single line comment or multi-line comment style base on the number of code. Thank you for your reply though.
