How to comment and uncomment codes at multiple place within my project at the same time?I am using VS 2010 trial version to develop a VB application.Some of functions only should be showed to developer, not to users. So I must comment them and uncomment them many times during the process of development. please note that those codes are located in many locations and many VB files within my project.
Can I do this in a conveninent way, just clicking a button, or just defining a const or "#define something", something like that?

View 2 RepliesI am right now in an project using VB.NET and needs to translate this C# code into VB.NET
oldCommand.CanExecuteChanged -= commandReference.CanExecuteChanged;
newCommand.CanExecuteChanged += commandReference.CanExecuteChanged;
For me it seems like the an event hooking up on an another event?But I have tried everything to translate this into VB.NET code?I have found out that EventHandler management in VB.NET is far from as good it is in C# as many other things.

View 2 RepliesI am creating a password managment tool and for the storage I will be using a text file, I want to encrypt so I decided I will use the Rijndael cypher. I have found source code which does this to a file:
http:www.codeproje...ncryptFile.aspx. It is well explained but I am but still struggling to understand parts as I never looked at cryptography at all before.
Private Function CreateKey(ByVal strPassword As String) As Byte()
'Convert strPassword to an array and store in chrData.
Dim chrData() As Char = strPassword.ToCharArray
'Use intLength to get strPassword size.
[Code]...
This assigns all of bytekey with half of the hash from byteresult. Am I correct? If not why not just use SHA256 instead of SHA512 as you are only using half of the hash. If somebody could explain this to me this would be great. Already confused and this is just creating the key, then the IV needs to be created(not sure what an Initialization vector does) then the encrypt/decrypt function. I think I will struggle understanding this but I am going to try.
I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).
I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?

I am trying to translate some VB codes to C++. And I am not quite sure what this line does.
IIf (n& 1=1, 0.0005, -0.0005)
I know what IIf(logic, true_value, false_value) does, and I guess the & operator is supposed to concat two strings. But I am not sure what the intention of using "n & 1 =1".

View 2 RepliesThis is for vb.net I've been working to develop a system which involves computation.What I've been trying to develop in my program is, I have a textbox where user will enter a numeric value,there is a button and a label below and in the first place the label should be set to zero. Everytime you enter a numeric value in the textbox and click the button it should add the value in the label and should save the value in the label so even if you exit the program whatever the last value displayed in the label should remain the same when run the program again,I believe it requires a database to save the value.Basically its like with payment system which saves the total amount of all payments made.
This is how should it works,say for example,if you will enter 1,2,3 it should save the sum value which is 6 in the label even if you close the program and when you run it again and enter another value it should add to the current value which is 6.
In C, Pascal, and C++ it is possible to use the FormatMessage function to retrieve a "friendly" error message that corresponds to a COM HRESULT error code. This question contains sample code that demonstrates the C++ approach. Of course it would be possible to build a managed C++ assembly to perform this function for C# and VB.NET code, but I'm wondering: is there a way to translate COM error codes using the .NET system libraries?
View 2 RepliesI need to be able to write data to a binary file. No problem - I have a test app I've knocked up that reads and writes to them fine, however the format uses C0 and C1 control codes, and I have no idea how to write them properly. The SOH, ENQ, DLE, NUL type of thing. I'd post some but they are non-printing. I know what they mean and what they do but have no idea how to write them.Basically we are writing our own system that generates test data files for import by another program. My files that I write have the correct number of fields and correct value and formats but because I can't get the tags to write they data is imported incorrectly. I've spent days reading up on it but can't find what I'm looking for.Not dealt with binary data files in VB before so this is all new.

I was converting my VB6 codes to VB 2008. There is a section i use a third party application (Microsoft Excel) to print report. But now VB 2008 is not accepting one of my statement. the statment is shown below in bold letters.
oSheet.range("H" & Row & ":" & "J" & Row).Value = Array(InvoiceNo, , Today)
it works in VB6 but fails in VB 2008 because of the Array statement, is there any replacement for this in VB 2008.
I'm recently writing an app that is localizable and have several lauguage resources built within VS 2010 SP1. But now I came into a problem -- it seems that VS has modified one of the Designer.vb unregularly.The problem reveals like this. Whenever I want to change the main form's Language from Default into fr-CA (for eg, and with Localizable true), and after I save or run the project, then VS shows me with dozens of a same errors: 'Resources_ fr_ CA'is not a member of 'myApp'. The amount the this error I guess is depend on the number of controls on the form, but I'm not quite certain about that.Then I looked into the Designer file and found strange lines that were suddenly added by VS, they are somelike this two, not all these but commonly:[code]
The problem used to happened several times and it was passive before cos I can remove the lines one by one, using a text editor from outside. But now it is total nightmare, because, now whenever I set Language into French, the same problem MUST happen as saving the project. I can not debug or develop it with local language again, that is not any more a joke is it?

Me.TblTopicsTableAdapter.Fill(Me.MainDataSet.tblTopics)Right, let me try and explain better.
I have an array named COURSE_Topics. This array contains topic codes as string elements.Currently, my table adapter query looks like this:
SELECT [Topic Code], TopicName, NoOfCourses, Duration, StartDate, EndDate, [Level] FROM tblTopics
At the end of that query i need to add a WHERE [Topic Code] = - then list of topic codes in the array.
