View 6 RepliesUsing Quotes Inside String Variable?
Jun 12, 2011I need to use quotes inside a string variable... but I don't know how.If I simply put double quotes at the start and at the end, the program interprets it as a closed interval, like if every quote is a string.
What can I do? I've searched here, but none of the results seems to be related with VB.net.
VS 2008 Declare Variables Inside Each Event Handler / Program Runs
Mar 29, 2010I am teaching myself VB, and when I try to run this program, I am getting "An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object." If I was to declare the variables inside each event handler, the program runs, but why won't it run when I make the scope public? Seems repititous having to declare the variables in every event handler. [code]
View 7 RepliesQuotes In Quotes Creates Error That Stops The Making Of A Desktop Shortcut?
Dec 27, 2011This should create a desktop shortcut but instead it spits out an error that is because of the quotes inside quotes. They need to be there, I know this is the problem as I have tried without them and it has worked. Another problem though is that it creates the shortcut (when Idon'thave quotes in quotes) but wraps the whole TargetPath in quotes making the shortcut unusable. Here is my code:
Dim input As String
Dim s As String = Environment.GetEnvironmentVariable("UserProfile")
input = TextBox1.Text

Accessing And Creating Variables Inside A For Loop?
Oct 15, 2011I have some variables that are distinct by numbers, like in1, in2...If I have for loop, how would I access those variables, using the counter, and attaching it to the variable?I believe in JAVA, you could just use in+ct... where ct is the counter to access the variable.also how could you make a new variable in the for loop?Initially I had variables declare outside of the for loop. The problem was how to access those variables using the for loop.
var_nm1 = in1.Text
var_nm2 = in2.Text
var_nm3 = in3.Text
Dim nmList(2) As Integer
[code]....
This is object oriented programming, and I made the textboxes in1, in2, and in3 using the GUI editor. that was so easy.
Arguments / Parameters And Variables Inside Shared Functions
May 19, 2011Well I am a new to VB.NET, converting a legacy system to .NET world. Recently I have been reviewing the already existing code since I joined the project quite late in the team. I find that there are many shared functions (not shared class) inside many classes. I doubt this may create some problem if two requests ( i.e two different HTTP request to the same method as it's a WCF application, of course exposed methods are not shared but internally called methods are shared) comes to the same shared method and both the calls to the method may have different method parameters/arguments, overwriting each other's arguments. In short, if shared method has a list of arguments which is going to be processed, is there any chance of inconsistencies in the light of multiple access to the shared method via two http requests.

View 4 RepliesVS 2008 Removing Quotes From A DataTable?
Apr 2, 2009I have a table with many values inside of it that might have single quotes around them. I need to create a duplicate table without those single quotes. I can't modify the original table as I need to use it, 'as-is' later.
I've done this with a table.Clone and using a foreach to loop through the rows and columns removing single quotes as I need and then putting that new row into the new table. It works and it's straight forward.....but
I'd like to do the same thing using LINQ. This was my attempt....
Dim myResults = From myRow In dtTable _
From myItem In myRow.ItemArray _
Where TypeOf myItem Is String AndAlso _
myItem.ToString.StartsWith("'"c) AndAlso _
myItem.ToString.EndsWith("'"c)
As you can see - I didn't get very far. I had trouble finding examples that weren't looking at a specific column in the DataRow. It looks like my code does pull back all the matching results - but I'm at a lose for how I can create a duplicate table/modify the values.

VS 2008 - Regex Replace To Replace Double Quotes With Nothing?
Jul 13, 2009I am trying to think of a regex replace to replace double quotes with nothing. Example:

Passing Multiple Byref Variables / Variables Fail To Change Calling Funct W/ Invoke
Sep 27, 2010I have code, shown below, that works all except for 1 thing: The variables being passed byRef get passed, but once modified in the else section of the "if me.invokerequired" code of RecordData, the variables are never updated in the calling function. To reiterate, the calling function does not receive the updated data that is in the variables custid and amt.When debugging, I see the data change in the else section of "if me.invokerequired", but once it returns from the callback the data is missing.[code]
View 15 RepliesDefine Some Global Variables Of A Class - Variables Occupy Memory?
Mar 23, 2012I define some global variables of a class as follows:
Private Class MyClass
Private var1 as Decimal
Private list1 as List(Of string)[code].....
But I found that after this form is closed, all above variables, var1, list1, list2 still exist in memory. I thought they should be collected by gc since the form is already disposed as I confirmed.
Add: I have monitored half an hour after the form is closed. But these variables are not collected by gc. I have an automatic update procedure on the form which uses above variables.Since the above variables still hold values, the automatic update procedure is always called which causes exception. (One quick fix is to check if form.isDisposed in update procedure. But I do not think this is elegeant. Besides, these variables occupy memory.)
