If you have a reference to the file, you will have to call Dispose on it before you can rename/overwrite it.

Also, please avoid using SMS Speak in the forums.

This code works fine for me..
System.IO.File.Move("C:\Windows\tempdoc.txt", "C:\Windows\Doctors1.txt")

'The process cannot access the file because it is being used by another process' can be caused either
a. tempdoc.txt is opened by some other application.
b. tempdoc.txt is still open by your application and failed to close.

Change access form when change screen resolution

Hi, I have design my own database application in Ms access with my computer screen resolution of 800 * 600. But when i change my screen resolution to 1024 * 768, I found that my database application control (button, list box...) seem too small and the form border do not fit with the screen anymore. Now I try to find the code to change the form size and control size to fit the screen resolution when I change it. Does anyone has any comment, resource or a sample code?

Web custom controls in VB.net ASP 2.0

David Pretorius6-Jun-06 14:32

Hi Guys,

just getting my head around web custom controls. I am hosting websites and in VS2003, i was able to upload my "controls" for handling contact us and other generic website tools as a webapplication to a website. And then overlay that with the personalised website details as another webapplication. Two .dll would sit there serving the two layers nicely

Now in VS2005, the directory is deleted when you upload a webapplication and the copy option is not tight enough to make sure you are uploading what you need.

SO, i decided to try and set up a webcontrol library, where i thought i could build my basic controls ie contact us, copyright, shopping carts and then easily reuse them across the websites i host.

I have read that the best way to share or reuse controls is custom web controls. I am finding it very diffcult to say the least.

I have used MSDN to copy code for simple web custom controls into a project called webcontrollibrary. This project I am then adding to a solution that has a webapplication there. Some of the basic custom controls will automatically appear to be dragged from the tool bar, more complicated composite controls don't.

I have read about making an assembly via the command prompt and then copying that to the bin folder or adding to the toolbox. But it seems that once added to the toolbox, if i go and update that control and reassemble the assembly, i have to delete from tool box, add back to toolbox and then drag from scratch each of those controls into all of the web applications that use them. Seems very messy?

I am surely missing something really basic. I can see how powerful the web custom controls will be, but managing the sharing and deployment of these controls across the web applications i build has me reticent about getting too far into them.

Thanks guys

HELP! Errors while attempting to import a DLL

b_girl6-Jun-06 11:11

6-Jun-06 11:11

Hey, I'm new to VB.NET (and have no experience programming in VB) - I tried to post earlier but for some reason it didn't work, and the second attempt is never as good as the first!

I'm using Visual Studio 2005 with .NET Framework 2.0.

Anyway, in my project I have a need to call rasapi32.dll, from what I understand I need to use an unmanaged code block in order to make use of this DLL. This is what I have so far:

<br />
Imports System.Runtime.InteropServices<br />
<br />
Public Class TestRASDial<br />
<br />
    <DllImport("rasapi32.dll", CharSet:=CharSet.Auto)> _<br />
    Public Function RasDial(ByVal LPRASDIALEXTENSIONS, _<br />
    ByVal LPCTSTR, _<br />
    ByVal LPRASDIALPARAMS, _<br />
    ByVal DWORD, _<br />
    ByVal LPVOID, ByVal LPHRASCONN) As Long<br />
<br />
    End Function<br />
<br />
End Class<br />

Now, I realize this doesn't actually do anything just yet, but I need to get the basics working first. So, the above bit of code gives me the following error:

"System.Runtime.InteropServices.DllImportAttribute' cannot be applied to instance method."

The word "RasDial" is underlined so I'm assuming that's the problem, however, I don't know how else to do this. I've tried searching online but can't seem to find much on the topic for some reason.

I would really appreciate it if any of you are able to help me out and point out what I've done wrong! You'd be a lifesaver...

Thanks a million...

The function must be shared.

Public Shared Function RasDial(ByVal .... ect.

hope that helps.

No problem, By the way you may be interested in this, although it's in C# and in purgatory for some reason, it may help you with figuring out the calls. most of it is readily convertable to VB.Net.

If I have 10 text boxes text1, text2, text3 ... text10 and a "start over" button

I want to be able to click the start over button and have the cursor jump to text2 no matter where it is in the tab sequince.

Start at text1,

(TAB) go to text6

Push "start over" button

Change text in text2

Is this possable?

How to get ProductVersion in .Net 2005

Steven J. Reed6-Jun-06 8:59

6-Jun-06 8:59

In my VB.Net 2003 web app I got the ProductName and ProductVersion from the AssemblyInfo.vb with the following code:

With Diagnostics.FileVersionInfo.GetVersionInfo (Reflection.Assembly.GetExecutingAssembly.Location)
lblVersion.Text = .ProductName & " -- Version " & .ProductVersion
End With

These values are Nothing in .Net 2005!

What gives? How do I get the values in .Net 2005?

Thanks...Steve

Where is your AssemblyInfo.vb file, in the project folder or in App_Code?
