The destination for generated files is determined by the project properties and can be modified to your own requirements if necessary.

ok, I guess what I meant is, does VS put some files in Bin, and other files elsewhere?

If it's not broken, fix it until it is

Yes. Take a look at the directory structure under your solution directory and you will see the other directories. You can also look through your project properties to see which part of the build uses which directories.

You could change the output path by simply setting the output path attribute in the project's Build properties.
They could be put elsewhere so long as all the dependent dll's are also available in the same folder.

By default, yes. But not mandatory.

It's configurable through the project properties build tab.

Hi All,

I am getting following error when I am trying to assign a null value or nuthing value to a variable of type Nullable(Of Decimal).

But for that variable I want to assign a decimal value or null value. The same kind of problem I faced with Nullable (of DateTime) too. It cant take a nothing assigned to it. If it cant take that value then why is it nullable(of Decimal) or Nullable (of DateTime) and System.Nullable(Of Integer) is also not taking null values (means nothing value in VB.Net).

Please help me in resolving this issue.

thanks in advance.

Below is my code: I tried by just putting variable=nothing also but didnt work.

If savRequestData.PropRequestWage IsNot Nothing Then
                               wagesegment = New List(Of ReqWage)
                               For Each temp In savRequestData.PropRequestWage
                                   Dim wage As New ReqWage
                                   wage.DailyWage = IIf(Not String.IsNullOrEmpty(temp.DailyWage), IIf(Decimal.TryParse(temp.DailyWage, tempDecimal), tempDecimal, CType(Nothing, System.Nullable(Of Decimal))), CType(Nothing, System.Nullable(Of Decimal)))
                                   wage.RequestId = request_Id
                                   wage.WorkDate = temp.WorkDate
                                   wage.WorkHours = IIf(Not String.IsNullOrEmpty(temp.WorkHours), IIf(Decimal.TryParse(temp.WorkHours, tempDecimal), tempDecimal, CType(Nothing, System.Nullable(Of Decimal))), CType(Nothing, System.Nullable(Of Decimal)))
                                   wagesegment.Add(wage)
                                   requestedamount += IIf(temp.DailyWage IsNot Nothing, temp.DailyWage, 0)
                               Next
                            End If

Sub Main()
    Dim d As Nullable(Of Integer)
    d = Nothing
    Console.WriteLine("d=", d)
    Console.ReadKey()
End Sub

Works fine for me. However, the line

wage.WorkHours = IIf(Not String.IsNullOrEmpty(temp.WorkHours), IIf(Decimal.TryParse(temp.WorkHours, tempDecimal), tempDecimal, CType(Nothing, System.Nullable(Of Decimal))), CType(Nothing, System.Nullable(Of Decimal)))

..is something I'd delete during a code-review. It's doing to much on a single line, making debugging harder. It's not C++, and there's no shame in using a line per statement.

C# statement var indirect val

Of course. Here is an alternate use of indirect access to textbox strings. Any suggestions?

static public int boxCount = 0;
static public TextBox[] tbox = new TextBox[16];
private void Form1_Load(object sender, EventArgs e)
{
 tbox[0] = textBox1;
 tbox[1] = textBox2;
 tbox[2] = textBox3;
 boxCount = 3;
}

private void loadBoxes()
{
 for (int x = 0; x < boxCount; x++)
 {
  if (tbox[x].Text == "")
   tbox[x].Text = "0";
 }
}

Re: C# statement var indirect val

27-Dec-12 7:23

No. There's nothing like that in .NET at all. C# is not an interpreted language so it's impossible to evaluate a string at run-time and treat it as code. It has to be compiled in order to work.

You've have to use Reflection to get the control using a string like that and get it's value. Though, you may want to think twice about doing this at all as Reflection isn't exactly speedy to use.

The other problem is that are you seriously calling your controls Textbox1, Textbox2, ...?? That's horrible as you have no idea what each textbox is used for.

OK. Thanks Dave. That clears it up. The text box values are not of consequence but if they are null it is a problem. Trying to add them to a listbox is rejecting null strings. Position in the list box is critical for each item added so a place holder needs to be added.

Re: Needed: PGP source code

Textbox.Text will never return null, though it can be an empty string. Those terms mean very different things, so don't confuse people (or search engines) by using them incorrectly.

Doesn't make any sense to me as it has nothing to do with the original question.

We have a new requirement that a daily file transfer of client data be encrypted with PGP. I would rather not rely on a blackbox solution, as I want to make sure that the file is not being secretly sent off somewhere.

Can anyone help me find .Net source code to do PGP encryption/decryption? C# or VB.net are both fine, I can work with either. I do not need -- and frankly, would rather avoid -- all of the other bells and whistles that have become common with PGP packages. All I need is file encryption and decryption using an public/private key that follows the PGP protocols.

Hi,
i am working with C# application, which has some memory leak problem. When i checked with profiler, i saw private bytes are being increased continuously and after some times it is getting crashed. Can any one tell me what is "Private bytes" and what is the main reason of its increase in size without any request .

Thanks,
Nishant

Without knowing anything at all about your application, this question is impossible to answer.

Is it a Windows Forms app, WPF, ASP.NET, Silverlight, ... What? What does the application do? What is it doing when this "leak" occurs? Is it idle? Is it doing something in the background? Is it using some 3rd party components? What's the error message, if any, when it crashes?

Where are you getting this statistic from? DO NOT USE TASK MANAGER!

Obviously one thing is apparent - something is still running.
So figuring out what is running might lead to a solution and at worse would at least localize where the problem is.

Hi,

I am using MSI to create setup. I already added prerequisite (.NET framwork 3.5) into MSI.
I have selected option i.e. Download prerequisite fromthe same location as my application
While installing setup on windows XP SP3 its showing error .NET framework is not installed on the machine. Setup is not installing .NET framework from MSI.
Even I added all framework files and folders into application folder and program files folder.

Is I am doing any wrong? can pls let me know the steps how can i used my prerequisite .NET framework 3.5 on windows XP SP3 even not framework is available.

Thanks

19-Dec-12 18:55

If you're using the Setup and Deployment project to create your .MSI, it will NOT install the .NET Framework for you. It MUST be installed before you launch your setup .MSI.

If you use some other install creation app, like InstallShield, that will give you the option of installing the .NET Framework for you.

Hi All,

I am using EF 1.0 trying to update a column called doc id which is nullable column, but the EF is updating the other column also along with this column. There is no other place that I am updating that column mistakenly.

Is there any way that I can avoid this kind of situation happening. Because it is happening only in Integration Env, but not in Dev. I dont know what to do now. Please help me.

Below is my code which is updating doc id field:

I have an application that looks at the system time and records the datetime. We give out demos and license by time.

One customer claims to have blocked my application from seeing the time so it always runs. He wouldn't say how but just said he would "not let it look at the time." Before I dig into this has anyone heard of this or know how to do it? He's not really a hacker but is tech savy enough to find things other people have done.
