Saving Text - Add Save Features Doesn't Seem To Work

Mar 11, 2010

I have made a text editing application and, as you might have guessed yourself, I needed to add save features. Well, what I have implemented so far is the ordinary "Save As..." feature which I made by using a common SaveFileDialog. Now it's time for the hard part. I need to add the "Save" function located in many Windows applications (Notepad etc.). This is what I'm working on at this moment but it doesn't seem to work.

PerformClick() Doesn't Work - How To Make It Work

Feb 2, 2011

I 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.

Dll Doesn't Work On Any Other Computer

Mar 15, 2012

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?

Express DLL Doesn't Work On Other PCs?

May 24, 2012

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).

The form is an About Us form so has nothing on it only a text box and a OK button.

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.

.net - Why Doesn't <ScaffoldColumn(False)> Work

Oct 2, 2011

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?

.NET Forms Authentication Doesn't Work

Mar 20, 2011

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")
