Capture output

I launch a dos program inside my program and then capture the command line output to my VB program. How to do this? Thanks!

When you shell out to your DOS application, pipe the output to a file using the '>' directive, then reed the file in after the program is done.

This is a very inefficient way to do this and will only return the complete result after the program has finished executing. Unsure | :~

Providing you've left the caves and moved into .NET, the more efficient way is to:

Dim myProc As New System.Diagnostics.Process<br />
myProc.StartInfo.UseShellExecute = False<br />
myProc.StartInfo.RedirectStandardOutput = True<br />
myProc.StartInfo.FileName = "ping"<br />
myProc.StartInfo.Arguments = "www.google.com"<br />
myProc.Start()

You have now taken control of the process and have access to the output AND input streams. You could even write your own version of command.com if you wanted. Smile | :)

The output stream is located at: myProc.StandardOutput

Im sure you'll find the rest.

Well that seems very elegant. I have to admit that I was unaware of how to do that.

It does only work for VB.NET however. I am not sure what Teir was working in (.NET or VB6).

Thanks.

I have implemented this code in a WebForm which basically gives me a remote command line into the server.

I never thought I would tunnel DOS over the internet.

This does make a few holes in the security of shared hosting as it effectively bypasses all permissions. While you may not by able to use System.IO to delete say C:\Autoexec.bat - you can upload a console app and execute that from the machines system account.

DirectX 9.0 has been released on MSDN! See http://msdn.microsoft.com/library/default.asp?url=/downloads/list/directx.asp[^] for more information and downloads. It's hefty, but I'm sure it's worth if for all .NET'izens that have been waiting for managed DirectX!

ActiveX DLL control help

I'm trying to create an ActiveX DLL control in VB but I'm running into one snag. I want a simple form in the ActiveX control that has a scrollbar and a few buttons. This is working except that my form/dialog is popping up outside of IE. I want it to show up in IE (using the OBJECT tag) like a control embeded in the web page. Any suggestions?

It seems like I just need to make the form a child of the main class or IE somehow.

' MainClass

Private TheForm As TimeAdjustForm

Private Sub Class_Initialize()
    Set TheForm = New TimeAdjustForm
    TheForm.Visible = True
End Sub

Private Sub Class_Terminate()
    Set TheForm = Nothing
End Sub

As far as I know there is no way to directly display a VB form on a web page. You would have to build your form as a visual OCX control.

VB6 app de-compiler

We have a small app written in VB6 for which an ex-developer has not put the source-code into Sourcesafe and consequently the source has been lost. A customer has stated that it is causing an error and we need to see what is going on. Does anyone know of a VB6 de-compiler/dissassembler?

Cheers

secondary thread to add data to the control

I have never seen a good decompiler for VB6 exe's. There have been rumors but I have never seen anything that has worked.

I’ve a WinForm application and a TreeView control on it. I’m creating another thread to add data to the control. So far I’m able to achieve this behavior, but sometimes secondary thread is not destroyed. I know it is not recommended, but I’d like to know more about my options and why I should not do this.

Thanks

There's a MaxLength property for the textbox which can be used to limit the amount of letters that can be keyed in

And to verify the type of data, you need to do some coding in the Textbox_Change() event

as for your first question, not too sure, but i think you can do some coding on the Change() event as well

how to control one form from another?

23-Dec-02 7:15

VB6 can not create DLLs that export functions like C++ can. It can only create COM DLLs.

Hi this is my first post here.
im using Vb.net and am a novice.

im going to create a program that i can use like a favourites program for internet addresses and files and folders within windows.
i can handle all of that but i want to use the same kind of control asthe one in the visual studio tool box.

you know the one with, kinda like vertical tabs and when you click one of the tabs it slides up or down revealing all thats in it i.e if you click toolbox it slides up to show you the contents of the toolbox. this is in visual studio.net

basically i dont know what this control is called but i want to use it as it is very neat looking.
also i would welcome any advice on how it is used as i cant seem to find it in any of my programming notes.

thanks
