Hi all,
I am looking for a bit of guidance for using a checkboxlist in Visual Studio 2005. I am wanting to use this to have each checkbox set to checked or unchecked, depending on a value contained in the registry. I have 10 items in the list at the moment.
Here[^] is a screenshot of what I currently have.
Any help on setting the checked state and checking the state of each individual checkbox within the list will be greatly appreciated.
Thanks, Andrew Robinson

Does anyone know where I can find a (preferably free) telnet component for .NET that will do 5250, wyse 50, and VT320 emulation? It does not have to do all three, but I need to use all three emulations.

I have a form with 1 button and several labels on it. I don't want the button to be the default if enter is pressed. I want the user to have to actually click it for it to work. I also don't want it to have that "selected" look with the dotted line around the text. What can I do about all this? Thanks.

1 - set the focus to another control
2 - write some owner drawn code, or download some from code project.

I have a simple vb.net gui application (an alternative file requester in a form) that I would like to run from the command line. It executes fine, but I find that I cannot send any output (a string representing the file selected) to the command line upon completion. It appears that "console.writeline" doesn't actually write to the console? Any suggestions as to how to send info back to the console window upon completion? Keep in mind that this is a gui app (not straight console).

First, what verison of VB.NET are you using?
Let's see the code that created your console and the code that is trying to write to it.

vb.net 2005.
As for "code that created the console", I'm not sure of what you are asking: For testing, I'm creating a standard windows form application (hence as I mentioned it being gui-based and not console-based). Call it MyApp for discussion sake. Somewhere in the code (in this case within the Form_Load event) I have placed a console.writeline("hello world") statement. I was expecting this to display to the console when the program is run from a console, such as:
c:\>MyApp
and display
hello world
accordingly. However, nothing is ever displayed on the command line after the program quits. I'm guessing at this point that console.writeline doesn't really write to the console if the app is gui/form based, even if it is called from the command line....?

Doesn't work that way. The console is not part of the process you launched and has absolutely nothing to do with the process at all, at any point in time. You can have multiple consoles open at once, so that app has no way of knowing which one to write to!

I'll wait to respond until I've sure you've read the second response I made....I don't think I was being very clear previously. I'm pretty sure that my vb task should be able to respond to the parent shell window...just not sure how

No, it can't. Not unless you specifically go and get a handle for any existing console window. It's just easier to create your own...

Upon rereading your post, a light went on in my head. You might be assuming that *I* am creating the console in which my code is running. The console is a standard DOS shell (cmd.exe) that is run by the user. *My Application*, while gui-based, is being run from that command shell as a commandline. I'm trying to get my app to print text to the shell from which it was called. In C, the closest thing would be a printf().
Hope that helps....

If you don't create the Console window, or at least grab a handle to an existing console window, you can't write to it.

Since you created a Windows Forms app, there is no such thing as a console that is attached to it automatically. Your app has to create one, or find an existing one. This was easy in C because your C apps were console-based, non-GUI apps and ran in the context of the DOS-emulator running in that console window. The consoles Standard In/Out/Error streams are at the disposable of the console app that is launched. This concept doesn't apply to Windows Forms apps since it has no use for those streams.
You can create your own Console window using:
Declare Auto Function AllocConsole Lib "kernel32" () As IntPtr
.
.
.
AllocConsole()
Console.WriteLine("This is a test...")

Hate to keep repeating it, but I cannot create the console: It needs to be an existing shell in which the user executes the gui app, then the string is returned to the (same) shell. It's like the event handlers injected into a gui app disable the "console-ness" of it.

OK. Well, the console you launch your app from is not attached in any way shape or form to a Windows Forms app. In other words, the parent process of the Windows Forms app is NOT the console process that launched it. There is no way for a Windows Forms app to know which console window launched it. It's exactly the same as if you launched it by double clicking the icon or typed its command line into Start/Run.
So, the only way to get the console window attached to your app upon launch is if you write your app as a Console Application, then create and launch your Form using Application.Run(). You'll have to create public properties in your form so you can get any return values out of it. Something like this:
Imports System
Imports System.Windows.Forms
Module Module1
Sub Main()
Dim myForm As New Form1
Console.WriteLine("Application startup...")
' Application.Run is a blocking call...
System.Windows.Forms.Application.Run(myForm)
' so, this statement won't execute until the form is closed.
Console.WriteLine(myForm.ReturnValue)
End Sub
End Module
Public Class Form1
Inherits Form
Shared Sub Main()
End Sub
Private _returnValue As String
Public ReadOnly Property ReturnValue() As String
Get
Return _returnValue
End Get
End Property
Private Sub Form1_FormClosed(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosedEventArgs) Handles Me.FormClosed
Console.WriteLine("You can write from the console from inside your form.")
_returnValue = "This is the return value stored in the form..."
End Sub
End Class

I now have an alternative.....Dave, this may be similiar to what you are suggesting, although it does seem to work despite some of the issues you raised. Someone on another list suggested changing the apptype to Console App *after* the app has already been created.
I didn't want to change the app drastically and get involved with the whole main/app.run stuff. Plus, I have several utility programs that can benefit from this. Apparently by creating the app normally (as a windows application) and using console.writeline to write to the IDE console for debugging can be the starting point. Afterwards, the app type can be changed (in the IDE Properties for the project) to Console Application. At this point, all the existing infrastructure still works, but console.writeline will now output to something other than the IDE console window. If the app is run from the IDE, it will automatically create a shell window and output to that. However, if the app is run from an existing shell, output will be sent to that window (as expected since this is the shell window that spawned the app) and the app runs as a gui-based application.
The best of both worlds.
The only bad side is that if the app is run from an icon, it will open a shell for it's output. This is acceptable for me since the app will always be run from an existing shell app.
Thanks for the help Dave!

You can do that. All you're doing is changing the startup code environment. How you're launching the form code (automatically in your case) is very similar to what I put up in the last post. The results look exactly the same, right down to the console window popping up if you double-click the icon. Now you know how to do it yourself instead of relying on a procedure that might not work in the next version of VS.NET.

This is really a black art, and resources on the topic are few. Try typing "windows driver development[^]" into Google.

how to use vb.net changing the registry of HKEY_CURRENT_USER "Control panel\colors" for each color?
Thank you.
Beginner

|

|

All of the values in that key are merely strings that represent RGB values to build a color. The first number in each string is the Red component, in the range 0 to 255. The second number is Green and the thrid number is Blue. ALl you have to do is build a string with those numbers and update the value in the registry.
You can learn more about using the Registry and RegistryKey classes here[^].

Thanks.

Why are you P/Invoking Win32 functions when the Registry and RegistryKey classes already do all this for you?

Thank you very much...
I use this two lines coding that works very well.
regKey = Registry.CurrentUser.OpenSubKey("Control Panel\Colors", True)
regKey.SetValue(StrSysColor(i), colorStr)

Not sure if this is best forum but...
I am trying to convert somebody elses old C component into a VB.NET version and in the process add some more functionality. Silly me... I don't know any C at all but having an educated guess. This following bit has me stumped. Can anybody help with the conversion.
<br />
protected void onMenuItemClick(Object sender, EventArgs e) {<br />
MenuItem item = (MenuItem)sender;<br />
if (MRUItemClicked != null) {<br />
string fileName = (string)_itemMap[item];<br />
MRUItemClicked(this, new MRUItemClickedEventArgs(fileName));<br />
}<br />
}<br />
Cheers
