The service has been developed using VB.NET and VS.NET on an XP platform.
On the XP platform, when I install a new version of this service it starts
by removing first the previous version, which is what I expect. Everything is
OK.
On a Win2003 platform when I want to install a new version of the same
service:
1. It does not remove the previous version
2. However, it interrupts installation because the service is already
installed
3. The service is not listed in the add/remove applet so I cannot remove it
from there.
Many thanks in advance for your help,

Vimal, You probably need to look at TAPI, the telephony API. In VB there are a few off the shelf components available. Lookup Exceletel on the web. They have a suite of tools for placing and handling calls. Be warned. This area is a minefield.

I have a treeview with 18 nodes - 17 of which, when selected, show the requested relevant form. The eighteenth node (Node 16)has 19 tvwChild sub nodes for printing different reports.
My problem is:
If Node 16, tvwChild sub node, is clicked without first clicking on any of the other 17 nodes, the treeview is closed and I am returned to the start (as requested at the end of the Sub) without a report being printed:
If I click on any other node first then on a tvwChild sub node the correct report is printed.
How can I change the code so that the selected tvwChild sub node prints without the need to click elsewhere first?![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

MAC Address could works, but I don't know how to get this with VB, when the command ipconfig you can, if you can make a process of this and get the stream you can get the MAC Address. Maybe, it's just a crazy idea.

I am making a game with tiles and when i draw the map i draw the tiles one by one, after one is drawn, it makes the next, in the next location, so theres just one image changing locations and images(form a string). i need it to keep the other ones there and draw the next one.
i think i want to do this with an array but im not shure.
what should i do?
----------------------------------------------------------
dim tile as string
----------------------------------------------
in the map load sub:
do
if textbox=1 then
tile=(location of picture)
end if
if textbox=2 then
tile =(location of pic.)
end if
-------------------------------------------------------
in the form1 paint sub:
e.graphics.drawimage(new bitmap(tile)tilept.x, tilept.y)
----------------------------------------------------------
thanks for your time

I am no expext, but I do know that if you are going to do an array you have do dim your tile a little diffently and you problably will need a timmer. First off I am interested in knowing if you are a student. Because I don't want to ruin ones learning experiance by giveing away to much code and then it is just copied into a form to get the grade.
But I will try to get you going on it.
Dim tile() As string '''I probably would use pictureBox
Also you will either have to put the number of how many images in the (21)
Or you will have to figure out a way to count of them and Redim them later.
Here is an example of how an array works. But will not help you for images,unless you can figure out how to convert the code to suit your needs.
Dim student() As String 'student is the array
Dim intCount As Integer ''intCount is the counter
If IO.File.Exists("A:grades.txt") Then 'This is used to check to see if a file exist.Not sure how that would be done for images.
my = IO.File.OpenText("A:grades.txt")
Do While my.Peek <> -1 ''This reads it to the end..
student = my.ReadLine ''Stores the data from a line in student
intCount += 1 ''keeps count of how many times it is done.
Loop ''repeats the process untill the end of the file has been reached. Btw the end of the file is identified by -1
Now you have to redim the the student to so you know how big the array is.
ReDim student(intCount)
my.Close() ''Always close any file readers.
But in your case I think you are looking for something more like this.
#Region " Windows Form Designer generated code "
#End Region
Dim bulb(47) As PictureBox
Dim a As Integer
Private Sub btnLights_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLights.Click
Timer1.Enabled = True
End Sub
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
bulb(1) = PictureBox1
Repeat this process for the amount of the images you use.
Also you must have a main pictureBox. Mine was a christmas tree.
The Bulbs are little bitmaps made in paint.
The next process makes them blink.
For a = 1 To 47
bulb(a).Visible = Not bulb(a).Visible
Next
These are just sniplets of code so they probably won't work without putting some thought into them. But doing this will make you learn it better than just given the code away. Also if I have explain something wrong some please clarify it. As I have just completed a begginers level class with a B. I am no expert and I have lots to learn for myself.

hey, thanks for your help but im not shure what your saying. I'm a student but In high school, so Im not trying to cheet lol. Im sorry for not saying this but I'm not using picture boxes but bitmaps.
I'll email you the code so you can see what I mean, If you dont want to download it then I will post the code later, my email is: p_dog_2007@hotmail.com
thank you, if you dont have the time i can wait

Does anybody know how to fill the fields of IE's web page
from within VB or C++ ? What if the page is secure? Of
course, there is no problem to fill all the fields by
hand. The question is how to do it automatically, by
running .exe or .dll.

I have a textbox control that gets incremented by one whenever I right click in it. This works fine, however I also get the standard 'edit' popup box as well that appears. Is there a way to cancel this popup box from appearing?
Thanks.
|
|
|
|
|
|
Yes, I'm using Net. I looked up WndProc in the MSDN library, but can't really figure out what to do here. I know that somehow I'm supposed to trap this popup menu so that when it appears, I just disreguard it. Thing is I'm not really sure how to accomplish that. I'll play with it a bit more and see what I can get to happen.
Thanks.

Hi,
I am using a treeview and I saw a neat way of adding your own type of nodes using a class derived from TreeNode. My class is the same as a tree node but it has a key property I can use to index into collections of other stuff
class TreeNodeCommand
Inherits TreeNode
Public Key as string
End Class
In order to make my code slick I then wrote two conversion functions, so that any nodes returned from treeview are converted to TreeNodeCommand...
Private Function CurrentNode() As TreeNodeCommand
Return ToTreeNodeCommand(tvwCommands.SelectedNode)
End Function
Private Function RootNode() As TreeNodeCommand
Return ToTreeNodeCommand(tvwCommands.Nodes.Item(0))
End Function
' Convert tree node item to tree node command item
Private Function ToTreeNodeCommand(ByRef prItem As TreeNode) As TreeNodeCommand
Return CType(prItem, TreeNodeCommand)
End Function
OK, thats the background. I have a treeview that refers to TreeNodeCommands rather than TreeNodes.
I have drag and drop support on this treeview, but I dont want the user to be able to drop a particular thing on the Root node. So in my dragover code I select the node in the treeview under the mouse and using my CurrentNode and RootNode properties I check to see if they are the same node....
If Not CurrentNode Is RootNode Then
e.Effect = DragDropEffects.Copy
End If
...but guess what. Every single time the IF statement executes, I get another node added to the tree, which is effectively a CLONE of the root node.
If I do this, which is perfectly acceptable, but not as slick to read then all is well...
If Not tvwCommands.SelectedNode Is tvwCommands.Nodes(0) Then
e.Effect = DragDropEffects.Copy
End If
You will have had to see this to believe it. No where does any single line of code get executed that does a ...Nodes.Add. Yet, new nodes do appear.
I can work around this, but I would be really interested to see if for some reason you think the Clone method of the root node is being invoked by the type conversion, or by some other means. I think that's what it is. The interesting thing is I override the Clone method in my derived class and it doesn't get called at any time.
So, I am lost in la la land with this one people. Any thoughts or similar experiences would be appreciated. Perhaps I am missing something due to my lack of .NET experience.
Apologies for the lengthy post.
Nursey

It does seem that the root node is being duplicated by the tree. Here is another case...
' This function reads nodes and adds things to another collection
NodesToCommands(DirectCast(tvwCommands.Nodes(0), TreeNode), _
CommandList.SingletonObject.RootCommandTree)
...
The first parameter tvwCommands.Nodes(0) normally returns TreeNode. Please remember, and forgive my repetition, but in my case it returns a TreeNodeCommand object.
If I had the DirectCast around this parameter all is well. If I do not then the tree from the root node down is duplicated and added back to the tree!
Each time I can find work arounds to this stuff, but why the hell is it happening?
