Can A Generic List Of T Be Passed To Function Similar To Way An Array Is Passed?
Mar 23, 2012
I want to pass a List of T where T is an object I've created that has about ten properties (strings, dates and integers).The lst passes to the function successfully. I am also passing an New T of the Object (itm as T).I can see all the values (see image below), but because it's generic I cannot seem to retrieve the property values and I cannot figure out how to iterate through the properties of each itm as they are retrieved in the For Each.[code]

I want to have a function that will create a list either of C1 or C2, to be used in some generic operation, such that

I wrote a Log class that details the exception, including the method name and its arguments list,but I couldn't find any way to programmaticly retrieve the arguments values.in some forums it was said that its impossible mission. I find it very odd.my arguments list looks like:
argA As String = ?
argB As integer (Opional, Default value = 2) = ?
etc. only actual values are missing.

I'm not having any errors from these pieces of code, they're just empty everytime. I'm wondering if I perhaps have created them incorrectly.
Dim l As New Log()
l.Log = "Attempted staff login with username [" & txtUsername.Text & "]"
l.LogId = 0
l.StaffId = 4
l.LogDate = Date.Now()
l.Insert()
.Insert() is picked up in my BLL layer by these two functions;

My issue is regarding overloaded functions of the already provided IIf function that would handle specific types. As you all know the IIf function provided returns objects, rather a specific type so for my needs I created a few overloaded function to do just that but with a specific type in mind. So having said I have IIf functions for types of booleans, strings, bytes, integers, etc etc.
Now my problem is when I'm trying to pass a byte value to this function that would return one of the two byte values. When I do this the designer keeps confusing my values as an integer value and calls for me to convert it to a byte. If I did this then it would defeat my entire purpose for creating these functions-which is to avoid any conversions. The only way I can solve this is by converting the whole statement itself or the true/false parameter parts individual to specify to the designer that these values are bytes. I'm just hoping there's a way of identifying the difference between bytes and integers..

Is there a way to write a single function that will control validating the input to any textbox? How to pass control of it.
E.g.: My second try was to:
Dim CurrentTextBox As TextBox << Declare a global
Write a function that uses the global textbox and takes in 2 parameters, one determining the length it has to validate and the second telling it what to do once the input is verified
Public Sub ConfirmInput(length As Integer, which As Integer)
If (CurrentTextBox.TextLength < length) Then
CurrentTextBox.BackColor = vbRed
GoTo DONE
ElseIf (CurrentTextBox.TextLength > length) Then
CurrentTextBox.BackColor = vbRed
[Code] .....
My first try was to pass a textBox parameter to the ConfirmInput function but I believe that's the same problem as above.

I am in vb.net and have a function that will be accessed by multiple threads. Everything inside the function uses local variables. However, each thread will pass in its own dataset by reference. From what I have read the local variables should be no problem, but I think the dataset coming in is a concern. How should I control access / execution of this function to make sure that it is thread safe?

VS 2008 VB/I've implemented an interface to a .com program written in c++. I'm trying to access a data structure array(uNewValues) of type PLCCOMMLib.ANALOG_CONTIN. uNewValues should be a datastructure array of several elements (iSigIDCount). My problem is I only get the first array element of the datastructure.I've tried several methods and looked into marshalling but don't understand how to implement marshalling if that is the correct option.
Code below:
Public Sub AnalogContinUpdate(ByVal iSigIDCount
As Integer,
ByRef puTimeDateStampGMT As PLCCOMMLib._FILETIME,
ByRef uNewValues As PLCCOMMLib.ANALOG_CONTIN)

We have migrated our Vb6 application to VB.NET using a third party tool. Now we are in a process of Refactoring and introducing object oriented concepts in the application.
In VB6, we were using structures in many places. As a part of introducing object oriented programming,
1. is it a good idea of changing all Structures to Classes? or Is there a concept of "Generic Structure" similar to Generic collections, Generic classes?
2. Can some one guide me any source containing guide lines or best practices for applications that are migrated to VB.NET from VB6 and implementing object oriented programmaing.

I'm very new to vbs scripting and am trying to set a System envinonment variable which will be used by a subsequent cmd file which is called by the VBS script which created the ENV varible.The vbs script creates the varibale correctly but the called CMD file does not find it. I thought a child process inherited its parent env settings. I understand the child can not change the parents env. why the cmd file does not see the variable, am I using the wrong shell command in vbs to call the cmd file or something?Here is the VBS script that simply sets a System varibale and the CMD file below which attempts to log it.on error resume next

Dim objEnv

Ok so I tried to make an application that will open a URL ONLY if 24hours has passed since it had previously opened. My idea is that it will save the time/date to a .txt (unless there another way which im completely missing?) when it is opened (only open if the current time is the saved time/date + 24hours) and rewrite it after every time.
When I say I tried, I mean I opened a project, realised I had no idea what to do and stared at the Form for 10minutes.

I have kind of a problem in a database well its suppose to save a date but like a string, well more like a char type, and i need it that way to do reports.So there to tables Ventas and VentasDD so they have the same information what ever is introduced in the form both those tables have the information, the information is introduced simultaneously.So this is how its supposed to be save like VENTAS image the VENTAS date is saved correctly But the when its saved on VENTASDD table the format for some reason changes even if its the same type and text and everything, like the image shows, the first record i modified it manually but it is displayed like the other 3 records

I have a form with its method being "get" that passes the variables and their values to the query string, respectively. However, it also passes the viewstate variable in the query string. Now, I have a very long viewstate value on the given page, and if passed in the query string, the viewstate variable will cause the page to error out, due to "too long of a query string" which happens to also be too long of a url.
I cannot merely remove the viewstate variable - I need it. But I need to pass the viewstate variable along via some method other than get when the form is submitted, while the other inputs of the form (the non-hidden inputs) are appended to the query string.
