musefan has given you the perfect answer. Just be aware that if the number can't be converted to an int you will get zero.

I have an extension method that I use when working with text/xml etc files to simplify stuff.

public static class ExtensionMethods
{
    /// <summary>
    /// Converts a string to an integer.
    /// </summary>
    /// <param name="value">The string to convert.</param>
    /// <returns>The integer value of the string if valid; otherwise, zero.</returns>
    public static Int32 ToInt32(this string value)
    {
        int result;
        Int32.TryParse(value, out result);
        return result;
    }
}

Now I can can just use something like

int intFromFile = stringFromFile.ToInt32();

If I might...
Is it considered really bad practice to do Convert.ToInt32 ?
I have seen stuff (and well, I have used it, too) like:

string x = "10";
int xInt;
try
{
xInt = Convert.ToInt32(x);
}
catch
{
xInt = 0;
}

Would that not do the same as TryParse?
Or is it an unnecessary way around it, or simply, crap?

var question = (_2b || !(_2b));

Not bad practice, possibly a little slower going via the Convert class but I would have to check the implementation to be sure.

The convert class is great for converting from a built in type to another (not just from string), but I would guess the Int32.Parse or Int32.TryParse methods would be perhaps a little more efficient.

How can i automatically increments the build number in an AssemblyInfo.cs?

Any example? using macro or function method?

MS, he say:
The version number has four parts, as follows:

<major version>.<minor version>.<build number>.<revision>

You can specify all the values or you can accept the default build number, revision number, or both by using an asterisk (*). For example, [assembly:AssemblyVersion("2.3.25.1")] indicates 2 as the major version, 3 as the minor version, 25 as the build number, and 1 as the revision number. A version number such as [assembly:AssemblyVersion("1.2.*")] specifies 1 as the major version, 2 as the minor version, and accepts the default build and revision numbers. A version number such as [assembly:AssemblyVersion("1.2.15.*")] specifies 1 as the major version, 2 as the minor version, 15 as the build number, and accepts the default revision number. The default build number increments daily. The default revision number is random.

I've tried this and I've never been able to get it to work. It always just gives me a version of "1.2.*" on the actual file.

Have you got it working williamnw? (Sorry for hijacking your thread 8kelvin)

For 8kelvin: There are two other options:

1) The AssemblyInfo[^] task can be used to auto increment the version number by modifying the assemblyinfo.cs file prior to the build being run. You just add an include statement to your project file.

2) There's a task in the MSBuild Community Tasks[^] project that can be used to generate a version number and write it into a generated assemblyinfo.cs file prior to the build running. Again, it just requires some additions to your csproj file (or msbuild script if you use it)

To be honest I have problems with both methods in my projects. We have large projects containing multiple assemblies and always end up with references screwed up because one of them is trying to reference versions prior to the number increment, or version numbers getting incremented twice or stupid things like that. This is the one area of our system I'm very unhappy with, but I can't find a decent solution.

you need to delete
[assembly: AssemblyFileVersion("1.0.0.0")]
in order to make it work.

Allocating opacity for a control in Win App ?

Hi.
I want to show a control (Like a textbox) with specific opacity !

How can I do it in Win App ?
Could you guide me ?

Thanks in advance.

I dont think it is posible with built in .Net controls.

You can set opacity of a from, which also alters any opacity for its own controls automatically.

You may have to make a custom control to handle your needs

It's not easy.

I worked with RTF a few years ago and it's a real pain. I never did anything with images though, sorry.

Try downloading the RTF Spec[^]. You'll have to read that and understand how images are stored in the RTF file, and figure out how you can extract them.

Try this article: Insert Plain Text and Images into RichTextBox at Runtime[^] It shows how to insert image in richtextbox so you might work it the other way around.

C# Windows Service and POP3 authentication

Hi,

I need to create a windows service in C# what will connect to a Windows Exchange Server via POP3 protocol, and fetch the mails from an account what will be same user on behalf the windows service is running. So I don't want to hard code the authentication infromation what is necessary for POP3 authentication, but I want to use somehow the user information on behalf the service is running.

Does somebody know how can I got the mentioned authentication information?

Thank You in advanced!

Partially...

I need user and pass too. I assume I cannot get it in readable format, so I looking for some kind off class what stores all logon information, and I can pass it forward for pop3 authentication.

Thank You!

Yeah, POP3 is as old as the hills and needs a username/password combination. Windows is not going to give you passwords for obvious reasons. I think you're going to have to create your own mapping from Environment.Username to a POP3 username/password combination.

I guess the password on Exchange will be the same as on the domain. In which case you've got a real problem I'm afraid. Bear in mind too that POP3 is a text based protocol which doesn't do encryption or anything like that, although I think Exchange can SSL it.

Rob Philpott.

According to the following link: http://davenport.sourceforge.net/ntlm.html#ntlmPop3Authentication[^], Exchange supports NTLM authentication for POP3, see if there is some property in the .NET classes you are using to access it that lets you specify the authentication type.
