When adding points to a point pair list they are designated as Add(byval doube, byval double). I need the x coordinate to be a dateTime value. Does anyone have any ideas on how to do that?
Thanks.

The details of how to do that are in the help documentation that comes with Zed Graph. I can't remember them off hand but you will find them there.

How do you kill child threads when the parent thread that creates them is stopped?
I have an application that will spawn multiple child threads, but when the parent process is killed, the child threads keep running in the background until they've completed the task assigned to them.
How do you make them abort at the same time the parent aborts? I don't have any control over when the Parent process exits and cannot handle exit events.
Thanks.

An app remains alive, as long as there are threads running that have their IsBackground set to false,
so set it to true for those background tasks that should not prevent your app from terminating.

The problem is not the main app exiting. The problem is when I terminate the app, the child threads continue running in the background until they've completed their task.
[Edit]
But MSDN documentation says
Any remaining background threads are stopped and do not complete
which is contrary to what I'm seeing. Am I doing something wrong? The fillip here is that this piece of code runs within SSIS. And this SSIS package is invoked by a Windows Service using SQL SMO. 
I'm outta ideas...

MSDN is right.
An app remains alive, as long as there are threads running that have IsBackground==false (the default value),
so set it to true for those background tasks that should not prevent your app from terminating.

I have an issue.
The InitializeLifetimeService method of some of my MarshalByRef objects is never called.
I wanted to know would such objects account for Memory Leakage.
Thank you.

Hi to all,
I'm tring to convert project form vb6 to vb.net.
In vb6, I used LenB to determine the size of type.
But in vb.net not supported LenB,
Can anyone tell me what function use instead?
|
|
|
|
|
There are no byte strings in .NET, so there is no equivalent of the LenB function.
If you have binary data you would use a byte array to handle it.

if there some way to use keys in some program for example (Ctrl + v) do something in program in vb ?
|

You need to explain better what you are trying to do.

i want to record sound from wavepad in vb by macro key in wavepad program can i do that ?

You can handle the keyboard events, maybe set myForm.KeyPreview true.
It is however much easier, if you have menus, to add a MenuItem for the action you want, and assign
a shortcut to that menu item. Then no extra code is required.

I have a problem with inheriting in VB that has been beating me for two days now. I have one base class, all the variables are private with public wrappers for set and get. I also have several derived classes.
The functions and subs have all been overridden and everything works fine, but I can not change the public properties to modify the set methods. Everytime I do, I get an error using everything but MYBASE.Whatever, but using the MYBASE calls gives a strange value and I can't find out how it is occuring.
My question is. Can I override one of the public properties and change how the set method works, or do I have to re-declare the variable in the derived class to do it?

If you want to override the behaviour yet continue to use the field on the base class you must change the field to be Protected. Private means it is accessible only to the class that defined it and no others. Protected means it is accessible only to the class that defined it plus any derived classes.

Thank you Colin. Every book and tutorial I found only mentioned overriding Functions and Subs. I was beginning to think properties were impossible to override, and that just didn't make sence.

Any member that you want to override has to be virtual (Overridable in VB). If you add a new implementation for a member that is not virtual, you will be shadowing the member instead.

Hi,
Sorry to say but I am not very clear about the issue you are facing. I would like to confirm whether you are using Mnemonics as short keys. If yes, then I would like to mention that Mnemonics gets activated when we press the Alt+ (underlined character). For example if you have defined the caption (Text) of a Button as “Click Me” (note the underlined C here). The button will be clicked automatically when user presses Alt+C.
If this is the behavior you are facing then please know that it is a default behavior.
I hope this helps. Please let me know if I have missed something.
Regards,
John Adams

You got my point. Thank you so much for reply. This is possible by small setting in system.
The option given works.
|
|
|
|

This is a system setting and has nothing to do with your code.
Right-click a blank area on your desktop and pick Properties. On Windows 2000, under the Effects tab, you'll find "Hide keyboard navigation idicators until I press the Alt key". For Windows XP, it's under the Appearance tab, Effects button.
