Hello!
I need to show an image on a Form, and not on the designer, but from the code
itself...
How can I do it?
Thanks!
Have a nice day!

On the Form itself? You could use the BackgroundImage property.
VB.NET
Me.BackgroundImage = New Bitmap("filePath.bmp")
C#
this.BackgroundImage = new Bitmap("filePath.bmp");

Managed C++:
this->BackgroundImage = new Bitmap("filePath.bmp");
C++/CLI:
this->BackgroundImage = gcnew Bitmap("filePath.bmp");
ps: I think you shoud use Namespace System::Drawing.

Say I have a project, a windows form project. In it I create one or more UserControl derived controls. I would think they automaticaly show up in the Toolbox, but apparently not. So how do I get them to show up? If i'm creating them within an EXE project (at least in VC++) I am unable to add teh EXE in the choose item when right clicking on the toolbox, so I'm wondering what the steps are to get the control on there in drag and drop fashion, without having to resort to hand coding it?
Thx.

I too had this same problem, but the Controls showed up after I compiled the app.

Well, I've been trying to get the Size of a Folder with .NET without using Recursion. There dosn't seem to be any property for it and all my searches have given me only ways of getting them using Recursion, which I want to avoid at all costs. Any Advice, Guys ?

The directory/folder structure itself is recursive and as far as I know there is no such information stored in any folder. Technically it could be done but if a file changes one should update this information of all the parent folders and that could make it quite expensive.
You could a tree structure containing this size information yourself and have it kept up to date by means of a service. Then you only need to ask that service for the size and you would have the answer immediately. But this is far more complex than the recursive algorithm. A unwanted side effect is that such service would take up CPU time and probably would decrease the performance of your disks. Do you have any requirement that ask for instantanious information?
If you just want to avoid recursion you could make an iterative directory walking algorithm but that would imply you should keep track on a stack where you have been. It might be a bit faster but it is harder to code.

Thanks Rob.
But, Yes, My App does require Instantanious Information. It is something like (Treesize), but also adds that it can actually operate on the files and folders. And, Since it uses a Chart and by it's Very Nature, changes the information about directories often, it does need instantinous Information...
And, I suppose I'd be doing some benchmarks about the time required to get the size of them by Recursion and iteration, but I think that It'd take a lot of time, especially for rather big Folders like the Program Files folder....

Well, I did run some tests, and it showed that it needs 1 minute 20 seconds to find the size of my primary partition, which is 13 gb full.... And, if i need to get the size of the Program Files Folder inside it, all the Files and Folders Sizes would be queried again! Sure, I could construct a Tree with the Folders and their Sizes, but i suppose there should be a better way....

Hi Yuvi,
Two ideas:
1) Monitor 'hot' folders with an other frequency than 'cold' folders. The folder program files is big but does hardly change where the temp folder may be far more active.
2) Use WMI.
You can get all kind of events from the OS. Maybe you can subscribe to file (create append delete) events. Then you know where the changes are. I have no experience with it but check http://www.codeproject.com/csharp/WMIproviderGuide.asp[^]
for a good backgrounder.
regards,
rob

Thanks for the Ideas, Rob. Will Sure check WMI out....

Hi,
You do not state the language but in .NET you could use the Proces class and specific the start method. See
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemdiagnosticsprocessclassstarttopic3.asp
for details or google: process class .NET
have faith,
rob

using this method Diagnostics.Process.Start(....)

I have code that allows me to basically write the contents of a richtextbox to a bitmap (sending a EM_FORMATRANGE using SendMessage). This code works fine, but it always draws the text "normal size" regardless of the setting of ZoomFactor in the RichTextBox. How can I get the "zoomed" verison of the text into a bitmap?
Thanks in advance!

Or any other architecture can be followed? if so please help me with sample of ur application.

Of course. It's a design pattern, not something mistical only Java can use. All you have to do is Google for "mvc c#" and you'll come up with all kinds of stuff. Even this[^] example here on Code Project.

Hi,
I have imported a project from VS 6.0 in VS.Net 2005.
When I compile it, it raise a link error:
LINK : fatal error LNK1104: cannot open file 'mfc42ud.lib'
With .Net 2005 should it use mfc80ud.lib ?? How I can specify it ?
Best regards,

I dunno. But if you have VS 6 then try specificy library path or copy to the VS2005 library path. Check Project settink.

Hi!
If you are using a windows system, you just need to use the win32-api GetUserName:
Declare Function GetUserName Lib "advapi32.dll" Alias "GetUserNameA" (ByVal lpBuffer As String, ByRef nSize As Integer) As Integer
Public Function GetCurrentUser() As String
Dim liReturn As Integer
Dim lsUserName As String
lsUserName = New String(CChar(" "), 250)
liReturn = GetUserName(lsUserName, 250)
GetCurrentUser= lsUserName.Substring(0, lsUserName.IndexOf(Chr(0)))
End Function
The imported function GetUserName require two parameters:
1. The destination string-buffer for output
2. The size of the username
Then, with substring and indexof, we cut all character "0" off and return the username.
