Visual Basic 2010 Two Textboxes And One Button

Jun 11, 2011

I have to make a calculator for school but I'm in a big dilemma. :( The thing is, I have this calculator with three textboxes and of course digits and operators. There's two input textboxes, txtInput1 and txtInput2 and then there's the buttons from btnZero to btnNine. My operator buttons automatically do the calculation and the output comes in txtDisplay which is disabled (so that you can't write in it).

And the problem is here, I want my btnZero to btnNine move their textvalue to my txtInput1 and txtInput2 as long as they are selected (so the cursor is blinking in it). Now I use "txtInput1 = txtInput1.text & btnZero.text" sure that works, but only for one txtInput. If I can't solve this I'd have to make all the buttons twice. ;( (Edit: If I press my operator button then "txtDisplay.text = (txtInput1 "operator" txtInput2)")

Function Call For Multiple Textboxes Using Visual Basic Studio 2008

Feb 17, 2010

I am working to make a function that will update the back color of a text box based on multiple variables values. I can write the code to do the calculation, but I am not sure how to make the function realize which text box to update (as I will have about 30 different boxes). Below is the code that I have for each box so far, but I will have quite a few more, and would rather use a function to reduce the amount of code, and also make it cleaner as well.

If sngPreviousPrimaryPropertyTotal >= sngPrimaryPropertyTotalCost Then
txtPreviousPrimaryPropertyTotal.BackColor = ColorProgramLightGreen
Else
txtPreviousPrimaryPropertyTotal.BackColor = ColorProgramLightRed
End If
[Code] .....

Or is there a way that I can tell the function that it's updating the text box that call the function in the first place? Say if txtBox1 has updated text and calls the function, then the function 'knows' to update txtBox1, but will update txtBox2 when it's called by txtBox2.

.net - Which Version Of Visual Studio 2010 Contains Visual Basic SharePoint Templates

Aug 5, 2011

Does anybody know which version of Visual Studio 2010 contains the full set of Visual Basic SharePoint Templates? I am about to embark on a project to create Visual Web Parts to be used in a SharePoint report.

At the moment I am using Visual Studio 2008 and even though the WSPBuilder is installed none of the relevant SharePoint templates are present.Having searched SO and the web, most advise to install the templates via the Visual Studio command prompt: devenv /installvstemplates

Alas the Visual Studio command prompt is also missing from my VS2008 installation.So, the question remains: which version of VS2010 contains what I need for pain-free SharePoint development? There is a rather large price different between VS2010 Professional and VS2010 Premium, so can anyone tell me if the cheaper version (VS2010 Professional) contains all the Sharepoint templates?
