Reference To The String In The Heap Is Passed Even When You Pass The String ByVal To A Method?
Mar 2, 2011So strings are reference types right? My understanding is a reference to the string in the heap is passed even when you pass the string ByVal to a method.
String myTestValue = "NotModified";
TestMethod(myTestValue);
System.Diagnostics.Debug.Write(myTestValue); /* myTestValue = "NotModified" WTF? *[code].....
And what is going on under the hood? I would have bet my life that the value would have changed....

View 1 RepliesHow To Pass String Value To BackgroundImage
Oct 10, 2010I am writing a simulator for a complex technical system. I have created a custom control which inherits from the Button control. My project requires around 100 of these buttons, which function identically except for one difference. The background image cycles between 4 different images, (depending upon whether the button is pressed and/or the state of a Fault parameter), and this group of 4 images is different for many of the buttons. So when I drag a new control onto the form, I'd like to be able to specify which group of 4 images to use for this button.
Currently I'm using this syntax:
if not IsFault and isOn then
MyBase.BackgroundImage = My.Resources.FaultOnButton01
...
But this means I have to change each image in the code for each individual button. To simplify matters I though of using the Tag attribute. That way the class code can select the images by a process like this:
if not IsFault and isOn then
Mybase.BackgroundImage=My.Resources. + mybase.Tag + "01"
Obviously this syntax won't work, so my question is: How can I pass a built-up string value to the MyBase.BackgroundImage?

C# - Pass In A Property Name As A String And Assign A Value To It?
Aug 9, 2010I'm setting up a simple helper class to hold some data from a file I'm parsing. The names of the properties match the names of values that I expect to find in the file. I'd like to add a method called AddPropertyValue to my class so that I can assign a value to a property without explicitly calling it by name.The method would look like this:
//C#
public void AddPropertyValue(string propertyName, string propertyValue) {
//code to assign the property value based on propertyName
}
'VB.NET'
[Code]...
Is this possible without having to test for each individual property name against the supplied propertyName?

View 8 RepliesPass A String From VB 2010 To A Fortran DLL?
Aug 3, 2011I can pass integers, singles, doubles, and arrays of all these back and forth with no problem. But I can't figure out how to pass a string in Visual Basic 2010 to a character variable in the Fortran DLL. I keep getting the PInvokeStackImbalance error. I could just convert the Visual Basic string to an integer array containing the ASCII code for each character, send that, and convert back inside the DLL, but that's pathetic. There must be a simple way to do this.
I first tried using Dim txt(50) as Char in VB2010, and character*50 txt in the DVF F90 DLL but that didn't work.
Then I tried Dim txt as String in Visual Basic 2010 and made the string 50 characters long (also tried 49) but this didn't work.

I'm developing the dll myself using Powerbasic.
The dll expect a 4 bytes pointer to a safearray's handle. As far as I have understood it; the array's string elements must be passed in ANSI format. The code in the dll will then use OLE Api to get the LBound and Ubound of the array and the address of the first element in array.
Pass String Output From VB Class To VBA Module Via A COM Add-in?
Dec 11, 2011I am using an email verification program I have downloaded to test the validity of a given email address.I have setup a class in VB using Visual Studio 2010 with the required code that runs the check.I have then registered this as a COM so I can call it through VBA in Excel.In an excel workbook I have then created a module that calls the VB class. The excel module tests whether the email address typed in cell "A1" is valid or not. At the moment the VB class simply gives me a messagebox output saying "Success" or "Fail" which works fine.What I actually want though is for the "success" or "Fail" message to appear in cell "A2" next to the email address as opposed to the current messagebox output.

.net - Pass A String Variable Data From Form2 To Form1?
Nov 17, 2010It's a program that reads student data from a text file and displys it in a listbox(Form1). From there on you can add a new student to the textfile by clicking on "Add" button that shows another form(Form2) and you input the new student data into the appropriate text boxes. Afterwards you can press "Add" button(Form2), but the Add Student(Form2) window comes up again with all the inputted data gone, and if I place the new student info into the text boxes again and click "Add", the program jumps back to the Form1 and a message box suppose to say what was added to the textfile, but nothing was added except for empty listbox items.

C# - Pass An Integer As A String Parameter To A Method Without Calling .ToString()?
Mar 12, 2010In VB.NET, it is entirely possible to pass an integer as a string parameter to a method without calling .ToString() - it's even possible to call .ToString without the ()'s. The code will run without a problem, VB will interpret the integer as a string without having been told to. In C#, these would cause compilation errors - you are required to call .ToString() and to call it correctly in that situation before it will compile. Is there a way to make the VB compilation process check for the same things as the C# compilation process? Would it be best practice in a mixed team to force this check?
