I have struggling with this for a few days now and i can't come up with a solution, damn it I can't sleep.

I have a array of bytes (iv'e used the UTF8 encoding from string to bytes) but i wan't to insert 4 bytes (255 = &HFF) before the result from the encoding. How do i do this the easiest way? do i have to loop through all values in the array? that seems to be a huge waste of cpu.

Thanks. And a merry merry X-Mas!!!!

If you post the code maybe it will help us.

Imports System.Text

Dim myBytes() As Byte
myBytes = Encoding.UTF8.GetBytes("TESTSTRING")
Dim myStartBytes() As Byte = {255, 255, 255, 255}

I want the mystartbytes to be in mybytes(0,1,2,3) but not overwrite but to push in the value so the rest of the array is moved 4 steps.

Do you understand what i mean?... My brain has freezed up.... thanks for your help.

It seems that you need a different container, have a look to ArrayList class (that provides the Insert method as well the InsertRange) on MSDN.
Hope that helps.

Hi again....

I got it workin but I'm note quite happy with my coding.... feels like alot of unnecessary steps just for combinding two arrays with a few bytes in it.

Dim myMessage As New ArrayList

Dim myByte() As Byte = {255, 255, 255, 255}
myMessage.AddRange(myByte)

myMessage.AddRange(Encoding.UTF8.GetBytes("rcon popeye status"))
myByte = myMessage.ToArray(GetType(Byte))

In .NET 2.0 this is 2 lines

Dim byteList As New List(Of Byte)(New Byte() {255, 255, 255, 255})
byteList.AddRange(UTF8.GetBytes("TESTSTRING"))

Since in .NET 2.0 the List is Generic, you can use the ToArray Methohd to get a byte array of the byteList on the fly

Example:

Dim pass() as byte = byteList.ToArray

Or even in method calls:

Dim writer As New BinaryWriter(New FileStream("C:\test.txt", FileMode.CreateNew))
writer.Write(byteList.ToArray)

OP doesn't make any sense. I am guessing he wants to have something done at during setup of his app...

So get the information from the user once serialize it to the registry, ini file, or an XML file which ever you’re most comfortable with. On App start up, read the info try and connect, if the connection fails present the dialog to fetch the dB server information again, try connecting until it succeeds. Simple enough

TabIndex !!!!!!!!!!!!!!!!!!!!!!!!!

Hi some of you may be wondered , that is's easy that you can control of the tab index
I'm using vb.net 2005 and when I copy a control from on form to anther or from the form itself then when i go to requlate the tabindex , on Run mode when you press Tab key i found that the arrangement that i did doesn't work , and the tab control is following the ordering of adding it on the form ,,

your program is good but when the user found this simple disadvantage Frown | :(

Tab index is a property of each control. It doesn't need to be a strict 1,2,3,4 sequence, but it will run in numeric order, based on the values you provide, or the defaults.

Thanks Graus

I accept you as it's not neccessary to be 1,2,3 ...
you can make any sequence , I'm allready make it but on run time when you press tab key you find that the order of it isn't as you have changed,,

I know as it's so simple thing , and I did it on some new application I found that it's working as good ,

but on my project some times I copy controls from one place to another and then delete some and reAdd some .. etc , then I go to reEnter the TabIndex as any ordered numbers , ,, on run time I found this problem only on my project , ,,, I'm using some controls of Devexpress's controls , I don't know it's my make any problems Confused | :confused:

I don't know ,
I'm sorry for waste your time Rose | [Rose]

Is the TabStop property of those controls set to True?

Hi Dave

all of them all , TabStop is False /
Really I'm confused ,
and sometimes I found some labels it's location is changed by itselfes , and also I found sometimes the text of labels is Null , really Why ????

I'm using some controls of Devexpress controls that someone give me a full version of it with crack , you see , Are this controls make aproblem on my project ??

I became don't know any thing !!!!!!!!!!!! Confused | :confused:

The Tab isn't going to go to that control if TabStop is false.

Weird. Depending on the version of Visual Studio your using, try installing the latest service pack for it.

kindman_nb wrote:

The Text property can NEVER be Null (or Nothing in VB). It can, however, be an empty string (String.Empty).

Don't make me slap you silly. Here we are, a bunch of developers, who make a living off of writing code and selling it, and YOU and YOUR friends are stealing the very code people write to make a living. Sorry, all support for you ended right here until you go to DevExpress and pay for the package you stole. Then , you can talk to them about supporting the controls you bought.

Hi
At the first I'm using vb.net 2005 , I hope if any upgrading is allowed

Then second thing , thanks really thanks for all advices , and I considered you as my older brother who is steering me , but let me talking with you alone , and I hope you to be patient .

I'm a new programmer with vb.net , and I face a lot of troubles whose became easy after I know it , and I have many packages with vb6 , and I hate if anyone try to copy it without an authentication from me , then from here as I hate that all others are like me , then it isn't a straightness to copy any products of any one , really I feel with embarrassing

On few words I like to tell you some things
When you as a simple programmer want to design programs and sell it on a challenges life with high companies whose has the abilities of stuff programmers and money , what you can do on that life , the user when you try to show your products , he make comparison with others , then you found that you must use then high controls to give your program the magic touch, when you go to ask the price of it , that price is more than your ability ,

You found some friends add you all you products that you want and more ,
I will tell you a thing that you don't want to see , who makes the cracks ,,, they are members on your website , who is my friend which gave me this products , he is also a member of your website ,
I'd like to say that problem is widespread between the small programmers who don't have the ability to buy ,,,,
What I will do now to promise you to use the default controls of VB.Net , but I want to say a thing ,, the copy of VB.net I have get it free , the copy of WindowXP , Office XP , Adobe programs , Norton Programs and Macromedia programs …. Etc ,

Tell me are all programs on your PC is licensed ??? then if you have then you are like all computer users ,
My friend, who has the ability to buy all that products which is necessary , when you navigate on the web you will find that 99% of users on the world have a lot of programs without licenses ,

Yep. I have too much to loose if they're not. Spending the $600 on a library is a lot cheaper than $250,000 per incident if I'm caught.

Which brings me to the problem that you have. Sure, you can develope applications with a stolen library and sell them. But, if DevExpress finds out about it, they can sue you for, say $250,000, PER COPY of your application that you sold using their controls. They can also go after your customers for the same thing, who are then going to come after you to pay the bill.

Hmmm, $600 vs. potential say $1,000,000... The choice is pretty obvious to me.

The other side is that you're a small development house and can't afford the cost of the controls, so you have to make up for the "pretty controls" with higher quality, rock solid code and supieror support for your customers. THAT brings in the money to get the prettier controls. Even DevExpress had to start somewhere...
