Has anyone succeeded in creating a class library solution/project in VB.net VS2010 4.0 Net Framework for COM to run on WindowsXP Excel 2003. I created a dll which changed specific data in an excel worksheet. The dll worked just fine on the development computer but wont work on any other. I downloaded .NET 4 framework onto the target PCs and used RegAsm.exe to register both the .dll and .tlb files in the registry. That worked OK and the dll is visible as a reference in excel and can be ticked. The error message I get is RunTime Error -2147024894(80070002): Automation Error The System cannot find the file specified.
I also tried creating a Setup and Deploy project in the original development solution but this created just a vbproj setup file which the target PC cannot read (no VS installed), I hoped the project would create an EXE file I could use. Does anyone know any links that describe how to do this type of stuff as most links I have tried are either for Windows Forms projects are are way above my knowledge. Maybe someone out there has already succeeded with this sort of activity?
Created two userforms in a single ms Word document, along with code, plus a macro on my laptom (Vista). Saved to flashdrive. At work I opened the word doc from flashdrive, but did not fine userforms, nor code & macros. There was a macro from another file I once worked on, but not the stuff from the file opened from the flashdrive.

if they choose to use a networked version of my software, I will need the main server doing the authenticating. This is a problem, because from what I understand, it is quite easy to clone MAC addresses. I have looked into using the CPU ID and the HDD ID, but those are not unique, well at least I don't think so. Reason why I say they are not unique is because someone has the exact same CPU ID as me, and the HDD ID changes from partition to partition (same drive). Maybe the HDD ID is a partition ID instead? Anyways, I was thinking maybe I could get the Physical serial number of both the HDD and CPU, but I have not been able to find anything yet.

View 1 RepliesI have read about Network.Downloadfile and I think I understand it! I want to know if there is an easy way to test a files date modified before downloading it. I have a lot of files in the folder. I really want to "sync" the folder. I don't want to copy every file every time I want to only download the file if I don't have the file in the destination location or if I have an Old copy.
View 4 RepliesI have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.
I have a form that works on my local Machine I created into. I have Office 2007 on this machine. I created the Form with the Excel 12 Reference.

Now the problem is once i create an appointment, task or contact from my VB.NET code and then if i open these item in outlook and modifies and save the content (like body of an appointment) then the lastmodification time of these item doesn't gets modified. It always shows the previous lastmodification time. This happens only for those item which got created from my VB.NET code.

So I have 2 data files, single dimension, that I'm trying to populate two rtb. If I comment one streamreader out the other will print. This also works in the vise versa situation. Does anybody see where I'm going wrong with this? They won't run together.
Dim Alpha As New System.IO.StreamReader("alpha.dat")

dim str as nullable(of string) is this syntax incorrect?

I have Visual Studio 2010 Express Edition. I'm using it to evaluate functionality before purchasing the real thing, but I'm having trouble. I want to build a DLL that can be used on PCs other than my development PC, that I can call from VBScript.
I follow the hundreds of examples out on the intranet and things still don't work.I have built a simple HelloWorld DLL with a function that returns "Hello World".I've been through all the stuff about making the assembly COM visible, and the threads about Register for COM Interop checkbox missing. One person suggested editing the .vbproj file and adding a tag to turn on Regiser for COM Interop (which was not needed because it was already there).
Anyway, if I build my project and run my VBScript:
Set testdll = CreateObject("HelloWorld.Class1")
wscript.echo testdll.HelloWorld()
Everything works great. But....if I copy the DLL to another PC and register it with RegAsm, the VBScript fails with a "File not found" error on the CreateObject line of the VBScript.
In fact, if I unregister the DLL on my development PC and then register it with RegAsm, the VBScript now fails on my development PC. RegAsm said everything was okay and if I look in the registery using RegEdit, things look good, but it still doesn't work. The only way to get it to work again is to rebuild the DLL (which in turn, registers the DLL).
I'd like to be able to build a DLL which I can be registered and used on other PCs (without requiring those PCs to have Visual Studio 2010 EE and without requiring them to have the source and build the DLL).

I am getting a datarow from my dataset and some columns can be NULL.So I am trying to check for this using the IsDBNull function, but it just won't work. I have tried almost every possible combination. Can someone please explain to me how to use this properly?ser is a datarow and GUID is a column with data type: unique indentifier (so a Sytem.Guid)
user.GUID.Equals(DBNull.Value) Then .GUID = System.Guid.NewGuid
I tried using above, IsDBNull(GUID), guid = dbnull.value, guid is dbnull.value etc etc I am just getting this error: The specified Cast is not valid.

Why won't the button close the form? I'm puzzled, I tried another button just in case with the same result. UPDATE: I set a break point on Me.Close() and it isn't reaching it when I click the button, I created a new button and the same thing happened.

Its my understanding that by adding the ScaffoldColumn(false) annotation to an property in a class, that property will not added to the view when doing Add View. However even though i have added scaffoldcolumn false to properties i dont want added to a Create form, they are still rendered inthe create view. Is ScaffoldColumn broken? On page 552 in Pro ASP.NET MVC 3 Framework by Freeman and Sanderson, it states "If we want to exclude a property from the generated HTML, we can use ScaffoldColumn attribute. When the scaffolding helpers see the ScaffoldColumn attribute, they skip over the property entirely; no hidden input elements will be generated and no details of this property will be included in the generated HTML.
" Also the MVC Music Store PDF on p 77 indicates that the attrtibute will do the same -"Allows hiding fields from editor forms".They add it to the AlbumId property and then when the app is run AlbumId field is not shown in the browser. Is this attr broken?If i change a html helper to DisplayFor it does not appear in the form regardless of whether scaffoldcolumn is present. For example i dont have scaffoldcolumn false on Property PostTitle but if i change @Html.EditorFor(Function(model) model.PostTitle) to displayfor then it does not render regardless of the scaffoldcolumn attr. Also my Create view is strongly typed to @ModelType RiderDesignMvcBlog.Core.Entities.Post?
I have an issue with my .NET application and it can only be reproduced sometimes and only on client's location, which makes it extremely difficult to resolve. In the application the forms authentication is used. There is a login page to which every anonymous user is redirected. After user enters username and password, it redirects to DefaultURL or some predefined page. The problem is that sometimes when user enters correct username and password, it doesn't login, instead it just refreshes the login page without any error messages. After several tries of inputing username and password, user is able to login to the system.
See my login page Submit_Click code below:
Dim userName As String = tbUsername.Text
Dim password As String = tbPassword.Text
Dim returnUrl As String = Request("returnUrl")
