You may subtract one time from other if you store data in two variables of DateTime type.

Such as-

DateTime i,j;

j.Subtract(i);

I hope this helps Smile | :)

Dave already gave you the answer, is it really that hard to understand what he explained?

DateTime startDate = DateTime.Parse(Label1.Text);
DateTime endDate = DateTime.Parse(Label2.Text);
TimeSpan span = endDate - startDate;

Create config file in Visual studio installer

2-Oct-07 9:55

Both Dave and Chris explain how to calculate the difference, but you really need the date part also. In your example, the time rolls over to the next day. So you really need the difference from (I just made up a date) "10/2/2007 23:30" to "10/3/2007 00:30" (a difference of 1 hour). If you just take the time, then the date part will most likely be the same and then the difference is 23 hours.

Take care,
Tom

Hi Guys,
Application is almost done and now I'm trying to write the installer. Problem is I'm using an XML file for some of the configuration and I can't find how to create one using the installer.

Is there something built into visual studio that can do this or will I have to write create some sort of post-install script?

If you include the xml file in your Application project (e.g. the C# exe project), then set it's Build Action to Content (select the file in the Solution explorer and then look at the Properties window). Then in your installer you can include the "Content Files" from your project. The files will then be copied to the install directory.

Take care,
Tom

Thanks Tom,
but how do I modify the file during the install process? It's going to include some database strings, and other application/user specific settings. We normally have a wizard that runs on the first instance of the website that takes care of this. For security we have removed this and want it done during the install.

(The old method wasn't perfect, but as a web developer, it worked for me)

Regards.
Joe

Enumerating over System.__ComObject

3-Oct-07 4:35

If you want to create a config file during the install process, then I would use a Custom Action[^]. Here's an example[^] that creates a database.

This blog entry[^] may help if you are deploying a web project. This blog entry[^] may help you if you need to troubleshoot an issue with your Custom Action.

Take care,

I'm trying to get the usernames of all the admins on the local machine. This is what I have:

<br />
DirectoryEntry admGroup = localMachine.Children.Find("administrators", "group");<br />
object members = admGroup.Invoke("members",null);<br />
           <br />
foreach (object member in (IEnumerable) members)<br />
{<br />
    DirectoryEntry admin = (DirectoryEntry)member;<br />
    Console.WriteLine(admin.Name);<br />
}<br />

The problem I'm having is with generics. The compiler is requiring a type argument for IEnumerable, but I've tried object and System.__ComObject neither of which will work. I know in .NET 1.1 that should of worked, but I'm at a loss of how to fix it now.

Re: Enumerating over System.__ComObject

Re: Enumerating over System.__ComObject

Make sure you are "using System.Collections;". The generic version of IEnumerable is defined in System.Collection.Generic (which is included in new C# files created by Visual Studio by default). But System.Collections is not included by default.

Take care,
Tom

Hi everyone,
I have a question here: I have a big project made in C# with lots of userforms and a huge code behind it. I want to convert the whole project to VB.NET 2005 project .Online convertors converts only few code not the whole userforms .. Sigh | :sigh:

Any ideas? :->

Thanks,
Dan

SharpDevelop (ic#code -http://www.icsharpcode.net/OpenSource/SD/[^]) Has an option to convert the current project to VB.NET (or Boo, apparantly). It also converts back between the formats.

There are C# to VB converters (not online) that convert entire projects. Just google on "C# to VB converter".

Hi,
Thankyou both of you for help. Big Grin | :-D

When I tried SharpDevelop and converted the project but when I open it in VB.NET it showed me 210 errors !! & the forms can't be loaded in designer mode ! WTF | :WTF:

And the http://www.tangiblesoftwaresolutions.com
convertor converts only first 1000 lines . As In my project there are over 2000 lines of code so it everytimes shows that "No Line Of Code Converted !" Sigh | :sigh:

What to do now ??

Thanks,
Dan

I'm trying to figure out why you would want to do convert the library into another language. Except for the syntax, CSharp and VB.Net have access to the same libraries. And are compiled down to the same thing.

As a C# developer the convertors have only been useful in letting me understand the VB language. In the end it was easier to leave things they way they were and create a new namespace.

It's working programme not a library & I want to run it in VB.NET so I was looking for such things..

Yes, Now I am planning to rewite the code so that I can learn VB and my work will be completed ... Wink | ;)

Anyway , Thanks for help,
