you can't do Serial Port communications unless you use .NET framework 2.0, which includes the SerialPort class.

Has anyone seen or programmed the following:
Say in excel you have are using recurently arrays of numbers. is possible to have a function that would store this array in memory with a name. something along the line of
=buildobject(Name, array). then anywhere in excel it would be possible to process, modify of this array or even display this array. Fucntion to delete those variable at the spreadsheet level would have to exist too.
I have tried to do that in VBA but I couldn't find a way of creating abitrary named global vriable from a function, the variable seems to have to be define at the vba level.
many thanks

Sorry, you're going to have to write it yourself. No one here is going to just give you an entire app like that. Besides, this reeks of homework. Why should anyone do it for you??

Hello Everyone!
I am programming graphic program.i use doublebuffer technology to draw graphic to bitmap object.Using e.Graphics().DrawImage(bmp, 0, 0) to draw bitmap object to panel in panel paint event.It's really good idea.Thanks to Dave Kreskowiak.
I do need to zoom in\out the graphic.and i use e.Graphics.ScaleTransform(xscaletran, yscaletran) in panel.paint event to do it.But problem happens.pen size changed too.
i think i know something about it.The method graphics.scaletransform just draught\extrude the graphics physically.
Do i have to redraw bitmap to zoom in\out the graphic?
Thanks for all replies!
Best regards!

Hi all .There is an external listview application and i want to change the color of selected text item. i be happy if some one show me how that can be done. The item is already selected and i have its class name .Thanks
|

To clarify, you want to change the color of an item in a ListView that's inside a different application?? If this is true, then you can't do that. You would have to replace the rendering code for the ListView in the other app. This being a HUGE security violation, there is no support for doing this...

Hi, this is realy importent to me.
I need to set a new array, from a SPLIT function, and I need to get it's length.
The question, is HOW?
This is my snifft, what's wrong?:
<%
arr = Split("b;c;d ;e", ";")
For I = 0 To Len(arr)
Response.Write(arr(I) & "
|
|
|
|
|
You can get the length of an array using UBound, not Len.
arr = Split("b;c;d;e", ";")
For I = 0 To UBound(arr, 1)
Response.Write arr(I) & "..."
Next

I am trying to retrieve a webpage using HttpWebRequest. My program works fine from home but if i try to run it from work and a few other places I get the following error
An unhandled exception of type 'System.Net.WebException' occurred in system.dll
Additional information: The underlying connection was closed: The server committed an HTTP protocol violation.
I believe that I read somewhere that in Windows XP they implement some stricter rules for exceptable responses or something to that effect. I dont remember exactly it was awhile ago.
I would appreciate any help I can get with this situation

I found a way to fix the problem by creating a .config file for the executable with the following inside it.
<?xml version="1.0" encoding="Windows-1252"?>
<configuration>
<system.net>
<settings>
<httpWebRequest useUnsafeHeaderParsing="true" />
</settings>
</system.net>
</configuration>
However I would still like to find a programmatic solutions to the problem that way i dont have create a .config file for every executeable.

Hi,
Thx a lot. Another question. If I want to open the program with a function initiated automatically, is that possible? For example, if start button is clicked, then paint is opened with the save command initiated.
|
|

No, there is no way to do this. If the app you're launching doesn't support opening certain items on launch, then you can't do it, period. This kind of functionality, also, doesn't have any standards defined for it, outside of DDE, so it's implementation would be entirely up to the application your trying to launch, if it supports it at all!
The only other method, though unreliable, would be to use SendKeys to try(!!!) to send the appropriate key strokes to the application you launched to get the functionality you want. The problem is that you have to launch the app, then wait, somehow, for the app to finish loading, then send the keystrokes. Also, between the time the app is launched and the keystrokes are sent, pray that the user doesn't hit any keys and doesn't click on anything with the mouse. Oh! Since Windows is a shared system, you also have to hope that no other application running in the system steals the input focus during that time too!

Hi,
Do anyone of u know how to open another program/software from a vb.net project? For example, if the user click a certain button, it will cause a program(paint, for example) to open. Is it possible to do that?

Newbi to the whole appdomain-ting but my understanding was that it is a controllable area of a process where I can load code where I can enforce security and at any time unload it.
I want to use it to extend my applications functionallity and at any time given a specific term can unload from memory and eventually restart. This way I could have memory intense parts loaded when I need them instead of all the time.
However I don't get this to work but I'm probably doing some beginners error?1
My code goes something like this:
AppDomainClient<br />
- Plugin.vb (class implementing AppDomainInterfaces.IPlugin)<br />
<br />
AppDomainInterfaces<br />
- IPlugin.vb<br />
- IPluginFactory (Inherits MarshalByRefObject)<br />
<br />
AppDomainApplication<br />
- MainForm.vb
I start the MainForm by creating an AppDomain. The appdomain object is passed to an instace of the IPluginFactory and used to CreateInstanceAndUnwrap an instance of the Plugin class. The Plugin class is returned as the IPlugin interface to the MainForm. In the constructor of the Plugin class a method EatMemory is called which allocates a very big string. This workes fine and the memory allocated by the application goes through the roof!
When I try to unload the AppDomain I don't get any errors but the memory is still occupied with the same number of bytes as before I ran the unload command:
AppDomain.Unload("MyCustomAppDomain") I was expecting it to decrease mack to what I had before I loaded the Plugin?
