View 4 RepliesForms :: Can Make Variable Actually Seen As A Variable?
Feb 17, 2011I have a VBA form in Microstation I am using to try and help automate a task. The only problem I am having is I am reading a textbox (Filebox.Text) and setting it as the variable (FN). It works, because I used Msg.Box (FN) to test it. However, in two of the lines of code, I am trying to use (FN) to pass the typed in filename to the command to run in Microstation. Unfortunently, it gets passed on as (FN).dgn instead of the actual filenale typed into the textbox. Is there a way I can make the variable actually seen as a variable? Code on Pastebin: url....Also, not sure if this is the right section, 100% new to VBA, coming from a world Bashed together.
View 3 RepliesMake One Variable = Two Others Instead Of Just One?
Jun 10, 2009I posted this before and got a few answers that haven't worked for me so far. Therefore I'm going to post part of my code so you can see what I'm talking about. The highlighted part is what I pulled from another post and it's not working for me right now. I'm using visual studio 2008 and the program was written in Basic. I pulled most of this program from the net and started tweaking it to my needs, If you're familiar with arabic you will understand the letters, if not, just use A and B for the variables.

View 7 RepliesMake A Textbox Choose What To Name A Variable?
Oct 19, 2010How do I name a variable depending on what is in the textbox?
Like would it look like:
Dim (textbox.text) as string
etc.
The reason I want to do this is because the user is gonna click a button to create a task. When the button is pushed, a label is created by the code I already have, the problem is, I want them to be able to click the button more then once and new labels will appear below the one that just was there. By being able to name a variable by what is in the textbox, I will be able to do so many things.
Make A Variable Accessible To Any Module?
Dec 30, 2009I have an issue with an app i am writing, i need to make a variable accessible to any module or class within the project but that cant be accessed outside of the app as it is accessing info the end user shouldn't have access to.
Ok, well a practice i have gotten into in the last few years is to declare a module on the same page as the main form and declare variables either friend or public (global variables). with my app public is not good so i tried Protected Friend but i cant use this within a module.
I tried placing it at the top of the main form but one of my classes can't access it, what would be the right way to do as expected. besides the main form i have 2 classes call them class1 and class2:- main interacts with both classes class1 accesses class2 class2 doesn't access class1

C# - Make A Variable/method/class Name Descriptive?
Aug 7, 2009Sometimes to make a variable/method/class name descriptive I need to make it longer. But I don't want to, I'd like to have short names that are easy to read. So I thought of a special addin to IDE like Visual Studio to be able to write short names for class, method, field but be able to attach long names. If you need to - you can make it all long or you can make single name long. If you want to reduce it - use reduction, like two views of the same code. I`d like to know what others thinking about it? Do you think it is usefull? Would anybody use the kind of addin?

Variable Declared Inside A For Loop - Make This To A Compile Time Error?
Mar 27, 2012Today I investigated a logical bug in our software and figured out that this is related to the way VB.NET thread variables inside a loop.Let's say I have the following code:
Dim numbers As New List(Of Integer) From {1, 2, 3, 4, 5}
For Each number As Integer In numbers
Dim isEven As Boolean
[code]....
The problem is that isEven is declared but not assigned.In this specific case, it would be correct to write dim isEven as Boolean = false but I haven't done this.In VB.NET, a variable that is declared inside a for loop keeps its value for the next itaration. This is by design: [URL]but this is also dangerous pitfall for programmers.
However, until now, I haven't been aware of this problem/behaviour. Until now.Most of our code base is C# anyway, which doesn't allow the use of an uninitialized variable, so there is no problem. But we have some legacy code that is written in VB.NET that we have to support. So the best thing would be to generate a warning or even an error in this specific case.But even with Option Explicit / Option Strict this does not generate a warning / an error.Is there a way make this a compile time error or maybe a way to check this with FxCop?
