Good morning.

Maybe i asking for too much. Let's have it like to know every key the user types. Then how can i proceed.

Thank you for your link, but the process is difficult, and they don't have exemple for vb code use.

I don't know what you can do for me

Modifying Selected EAP Type

I've been assigned a project to write a program that will change the EAP type that is set in windows. I then need to alter advanced settings under the changed EAP type but frankly i dont know if anyone here can help with that part ( it's called "SecureW2" http://securew2.com/uk/ ) I can't seem to find anywhere how i can either manipulate this through a windows script or a program.

For further clarification: The pulldown that i need to choose/change an item in is in Network Connections -> Right Click on correct network connection -> Properties -> Authentication Tab -> EAP Type. By default this usually says "Smart Card or other Certificate" and i need to change that to something else.

I've dabbled in the registry a little bit but i can't seem to figure anything out there either. Thanks to any one who can give me help on this.

Help needed - making vb6 LoadPicture faster

v6 LoadPicture method is slow.
I need to load quite a number of bmps onto an array of pictureboxes for an imaging app. Is there a quicker way to load images into picboxes?

instead of:

for i= 1 to totalimages
load picturebox1(i)
picturebox1(i).picture = LoadPicture(Path + cstr(i))
next i

i need to do this faster. pls help

There is no way to make it go faster, but you could load your images into an ImageList in Design mode, IIRC, and they will be compiled into your app as resources. You could then get all of your images into your PictureBoxes by fetching them from the ImageList.

Thanks RageInTheMachine9532.

This works if i have a few images. But i have 3MB of gifs (in harddisk), so i load them in groups of about 14(about 45kb in harddisk - translates to 3MB in memory). Problem is that LoadPicture is slow here.

If i load them into an imagelist at design (all 3MB), they could chew 100MB of memory!

Are you saying that the images you are using are small on disk (3MB total) but take up a LARGE amount of memory when loaded and rendered into a screen format bitmap (100MB)? If this is the case, no wonder it takes forever to load these. Without caching them in memory some how or expanding the images to a more native format (like .BMP), it looks like your going to have to put up with this problem.

I don't see how your going to get around this problem. You can't have speed and high compression at the same time. Generally, it's one or the other. This is because the LoadPicture function has to take a small amount of information and "draw" a large amount of graphics with it to create the bitmap image in memory.

I have used the following codes to print out text in Portrait

       Dim mFont As New Font("Courier New", 12)<br />
        Dim xPos As Single = e.MarginBounds.Left<br />
        Dim yPos As Single = e.MarginBounds.Top<br />
        Dim lineHeight As Single = mFont.GetHeight(e.Graphics)<br />
        Dim str As String<br />
<br />
        '--------------------->  Start to print  <---------------------<br />
        With e.Graphics<br />
            str = "SALE  SUMMARY  From Date1 To Date2 ..............."<br />
            .DrawString(str, mFont, Brushes.Black, xPos, yPos)<br />

You might want to try setting the DefaultPageSettings on the PrintDocument object that gave you the Graphics object your using.

Dim myPrintDocumentObject As New PrintDocument()
myPrintDocumentObject.DefaultPageSettings.Landscape = True

ADODB Connection events

RichardGrimmer2-Jun-04 3:33

2-Jun-04 3:33

Hi there,

Have an app that parses a .sql file, and executes on a connection object.

Have declared my conn object With Events, and am trapping various events so that I can log them.

When I run the following:

<br />
INSERT INTO Table VALUES (1,1)<br />
INSERT INTO Table VALUES (2,2)<br />
INSERT INTO Table VALUES (3,3)<br />
INSERT INTO Table VALUES (4,4)<br />
GO<br />
<br />

I am only getting my event handler triggered once, with RecordsAffected coming back as 1. What I need is for it either to tell me that 4 records have been affected, or hit the handler 4 times so that I can keep track myself, but there doesn't seem to be any way to do this - anyone know? Have tried trapping both the InfoMessage and ExecuteComplete events.

As an aside, when I do a DELETE FROM Table, am getting RecordsAffected back as 4, and am reading the file by LineInput & vbcrlf until I hit a GO, then conn.Execute strSQL

This is REALLY starting to annoy me!

Ain't gonna work like you want. The ExecuteComplete event will only get fired when SQL complete the BATCH of statements you sent it (remember the GO statement?), and will return the LAST record count affected, not all of them. You will either have to put up with this or send each command seperately, in your case, sending and executing each INSERT statement one at a time.

in the Visual Studio IDE do a search for the term "Q257819." (sans the punctuation of course) This should show you a listing of topics, the first of which is "HOWTO: Use ADO with Excel Data from Visual Basic or VBA" This should lead you in the right direction.

Command Line compilation in VB.Net

Hi
I am trying to complie windows application code written in VB.net from a command line.
I am getting errors as different classes involved in the project are referencing and using the members of each other, Thus creating a circular reference.

Now to complie 1 class in an assembly, I need other class already in an assembly for referencing. but oher class can not be complied seperately because it reference this class.

If anyone has a clue, Please help out.
Thanks & Regards

You haven't submitted any code, so we really can't tell you what your doing wrong. But, if I understand you correctly, how you are trying to do this might look something like this:?

Public Class A
    Dim objB As New ClassB
End Class

Public Class B
    Dim objA As New ClassA
End Class

IIRC, this is not going to compile because of the circular reference you are talking about. It's just bad object designed to have two classes completely dependent on each other. You're classes should be designed so that they are self contained modules and have a one way relationship:

Public ClassA
    Dim objB As New ClassB
End Class

Public ClassB
    ' no code dependent on class A existing here...
End Class

newbie question: arraylist and dictionary

hi there,

when is suitable using a dictionary instead of an arraylist and wayback?

i mean, i can't retrieve an object from an arraylist using a string key, is it?

there are other difference/condition? i.e. array dimension or whatever?

thanks in advance!

If you want to use a String type key to retrieve data then you have to use a class that implements IDictionary, like a HashTable or SortedList. There are other classes, but those seem like they'll fit your needs. Anything that implements IDictionary is accessed by a key/value pair. You give it the key as a kind of index and the IDictionary will return the value associated with it.

ArrayList's are accessed by an Index value, usually an Integer type.

There are a number of ways to send "messages" to other computers. Could you be more explicit in your request. Is the message aimed at a user, an existing process/application, another application you are writing, etc.?

Just use a socket and sent it a simple string saying it's done. There's exhaustive information about writing sockets on the net and in the MSDN.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
