Office Auto-mation :: Creating A New Instance Of Excel?

Feb 12, 2010

I'm writing VB code in Visual Basic 2008 Express and can't seem to figure out how to create a new instance of Excel with VB code. The most common answer appears to be setting an object variable to 'Excel.Application', but that gives an error (Type 'Excel.Application' is not defined).

Tools To Convert Option Strict Off Code Into Option Strict On?

Mar 28, 2010

I have to take over a project written in vb.net, which contains more than 400k lines of code written in option strict off mode. I want to build it under option strict on first before I do anything else -- which maybe converting it into C#. I found there's thousands of lines of code raises compilation error, mostly are about implicit type casts. Is there any tool would help to make it compile under option strict on mode if I don't want to correct every single line manually? Because it's really painful to add CStr/CInt invocation into every line of Code myself.

I have inherited a VB.NET application that I need to compile so I can run dorkumentation on it. I first received "Option Strict On disallows implicit conversion from x to y" errors, so I turned off the Option Strict option in the Project file.

C# :: Scripting Auto-mation Within Application?

Dec 30, 2009

The software company I work for offers data conversion as a service for new clients who have previously used other similar software. I've written a VB.NET application to automate common conversion operations, and have separate logic between known vendors.particular file layout has become rather common, but due to the nature of how this particular competitor's application stores information, certain fields mean one thing for one client, and another for a different client.Certain elements within this vendor's format change every time, so I've written the application to account for that. Because some data fields mean different things to different vendors, I have to change my mapping code every time. This wasn't an issue when I had one of these every six months or so, but these are becoming much more common and I would much rather find a way to further automate this process.

Use Of Option Strict And Option Infer

Feb 22, 2011

1. I have read that keeping Option strict on and Option infer off is good practice and will insure your code is tight and properly written. I would like input regarding this, pro's and con's from those who are in the know.

2. Having said that, I have set Option strict on and Option infer off in an existing program I wrote (that was working perfectly mind you) with them off and on respectively. I went through and cleaned up all the errors on the 'need AS' and casting of variables, but one is leaving me a bit put out.[code]

I have also read where using My.Computer.System.Directory.GetFiles() instead of System.IO.Directory.GetFiles() is probably not a good thing, but when I change to this I get no error, but also no dataI am thinking I should stay with the strict on and infer off but am really slogging through getting this code correct.Running Win7 on Dual Quad Core XEON Intel Extreme with 8Gb RAM.

Refreshing Form During Powerpoint Auto-mation VB 2008?

Feb 3, 2009

I have a VB 2008 Forms application which does Powerpoint automation -- I am opening owerpoint in a minimized window from within my app and am trying to periodically put update messages in a textbox on my main form while the automation is running (it takes a few minutes to complete), but my form window does not want to show these messages until the powerpoint operations are finished. It seems as if I need to force a window refresh or something on my windows form, but I'm unclear how to do that. Below is some code that I'm using that illustrates what I'm trying to do. When I run it, "Step One / Step Two / Step Three" do not show up on my textbox until after the Powerpoint automations are over.

Option Strict On - Is Better?

Jun 28, 2010

what do you thinkg about comment below? original article url is also suggested to read.I didnt get why my code will be faster if i use it on. anyone has good knowledge about it?

Although Visual Basic .NET allows you to perform implicit type conversions and late binding, you should avoid these practices. Implicit type conversions and late binding may lead to severe performance problems, runtime errors, code that is difficult to read and maintain,and sub-standard programming practices.Many VB.NET professional programmers believe that leaving OPTION STRICT OFF by default was perhaps Microsoft's worst decision in the VB.NET implementation. Use OPTION STRICT ON.

'option Strict On' Insists On This But Can't See Why?

Jan 25, 2012

I have an old programme that was written with 'option strict off' I have been steadily working through it mainly sorting out casting issues but have come up against some that I dont understand.for instance I have a checkbox called tickbox

dim Tickbox as new checkbox

later in the code

dim blah as boolean = Me.Tickbox.CheckState

but option strict insists i cast it as a boolean

dim blah as boolean = CBool(Me.Tickbox.CheckState)

surely the checkbox.checkstate is Booleean?
