Class Property Usage - Unable To Retrieve A Variable From On Class
Nov 14, 2009I have three class files, accounts.vb and transactions.vb in addition to my form.vb. I am unable to retrieve a member variable from on class from inside the other. When the combobox index changes, the program loads the correct account (checking or saving) from two different sequential files.

View 1 RepliesVS 2008 Use The Value Of One Variable To Call Another Variable Of The Same Name?
Feb 7, 2011I am trying to use the value of one variable to call another variable of the same name.I have 2 variable one called VAR1 and VAR2.
The variable VAR1 has a value of "VAR2"
The variable VAR2 has a value of "HELP"
I want to be able to get the value VAR2 from the variable VAR1 I have defined the value of VAR2 early in the code and now I want to call that value by using the value of VAR1.The reason I am doing it this way as I have a list of 50 variables that are pulled from one system. Each of these variables have the same name as the columns of a spreadsheet. The total number of Variable stay the same but the total column headers may vary each time. I need to loop through each of the column headers match them with the variable names and add the data to the spreadsheet.
VAR1 = "VAR2"
VAR2 = "HELP"
i =1
[code]....
This is the tricky bit...if the value of the cell(1,i) = "VAR2" How do I get it to display the value of the variable of the same name In this case how will I get it to display "HELP" when I only have from the VAR1 value "VAR2" I know my code will bring back the value as a string but I want it to bring back that string as a variable and display the value of that variable?

.net - Unable To Add A DLL Reference To VS 2008
Sep 4, 2009I'm trying to add a reference to the LAME MP3 encoder in my VB.Net (3.5) App.The DLL I'm using (lame_enc.dll v3.98.2) was downloaded from here:[URL]When I try to add the DLL reference to my project, I get an error:"A reference to C:\Lame_Enc.dll could not be added. make sure this file is accessible and that it is a valid assembly or COM component" I would just assume this was a corrupt download/similar but...
The archive passed an integrity test in WinRAR I tried re-downloading it JIC Next thought - the DLL is b0rked but...I've tried the SDK tools "genasm"(3.5) and "TlbExp"(2.0) and both say it's not a valid DLL.Previously when I've added non-.Net DLLs, VS has created an INTEROP Class for me. I'd ideally like to achieve similar with this DLL.

VS 2008 Unable To Use An Application.DoEvents?
Dec 11, 2009I have a unique situation in that I've developed a VB.NET application for AutoCAD. The way this works, you build your project into a dll and utilize AutoCAD API references when designing the project. From AutoCAD, a "Netload" command will load your dll into it's namespace to run. AutoCAD then essentially takes ownership of your application from here on out. The application is ran using a command defined in a method's attribute:
<CommandMethod("CommandNameForApp")>Public Sub MyCommand()
'Code Here
End Sub
Due to the heavy load of processing loops as it evaluates AutoCAD drawing data, processes this data, and generates many, many Excel reports, I've added a boolean property called Cancelled to my Progress class. When the user cancel's the process, this is seen by the process and further evaluation is ended and everything is cleaned up nicely. In order for this to work though, I have to implement Application.DoEvents. Without it, the Cancel feature will not work at all. With it, now instead of allowing the application to stay loaded, the Command method is fully closed.I have added a go-to point and simply verify that the application isn't closing because of a user-cancellation event. Here's what it looks like now:
<CommandMethod("WireShop")> Public Sub WireShopApplication()
'Initialize Configuration File Data
'Initializes ValidBlocks, MarginDistance, WindowDistance, and HelpFileName Properties
If ConfigurationFileInitialization() = False Then Exit Sub
[code].....
In my opinion, this seems a little hokey. However, I'm not that familiar with exactly what Application.DoEvents is doing in the background to understand how to "head it off at the pass".
