Thanks for the responses.

No. You are only declaring one strFile and re-using it like I explained in the middle of the last post.
If you want, you can also do
For x as Integer = 0 to strFiles.Length -1
'do operations with strFiles(x)
Next 'x
Strings being immutable refers to the fact that they cannot be changed. New ones are created and replace the last one.
1K strings is really not a lot and either method would work well. You will see object creation cost saving benefits when dealing with larger and more complex objects (like Streams/ UI Controls, iTextSharp PDF objects).

Just a couple small things I have wondered about and never really found concrete answers for.
Thanks for taking the time and giving full explanations.

I want to connect to an access database using vb.net. Can someone kindly assist with the codes to do this, including the declaration codes as well. I want to connect using codes and not the datagrid.
Thank you!

Thanks Bob for that response. That is a good site.
Please take a look at this code:
<Dim db as NEW ADO DB.Connection
Dim rs as NEW ADO DB.Record-set
DIM spath as String ' Path for the database
Dim SQLL as String ' Sql statement
sPath = app.path & "\DB\Name.mdb
>
Now the question is Bob: Is this code sufficient for connecting to an access DB? If not what is lacking?
Thank you!

i installled a window service that will access ftp server folder.
i get the following error The remote server returned an error: (500) Internal Server Error.. any idea pls
|
|
|
|
|
|
the article i found are on webservice. my application is window service. it actually execute the create folder before trowing the error
|
|
|
|
|
Your best bet to troubleshoot this issue is to mimic the steps that the windows service is doing.
Perform the same actions as the Service (login to FTP, read folders, etc) using a manual FTP client like FileZilla. Make sure you use the same login permissions, and are running the software from the same computer.

I'm developing a UserControl and I need to know when a user has changed the BorderStyle of the UserControl. I know that this is trapped in the UserControl's StyleChanged Event. But, I don't know how to determine which of the Control's Styles has changed and what it has changed to.
Does anyone have a code sample that would demonstrate this Event please.
Regards, Graham

Hi,
First Each n every control has its own style changed event if u still facing the problem in it then check the fous or active control in your form , One the control has focused=true n active means that control's border sytle has changed....
Hope this will help U
Unless u don't give ur hundred percent whatever u r doing till there is no result of ur work...
|

|

I think that I'm too simple to understand all of this.
Could you please translate this into something like English.
I can also speak French if that is easier for you.

Which thing is difficult to understand my english or the meaning of this what i said???
Which default control your are using to create a new user control????
There is 3 methods of doing this
1> Take default control eg textbox n add new features to create new textbox usercontrol
2>Use more than 1 control to create new user control
3>Create own user control without using any default
So which method you are using and which control???
May be i help u because i have also created user control before some time....
Unless u don't give ur hundred percent whatever u r doing till there is no result of ur work...

Seemed pretty clear to me, mind you your sig says it all - drop 10 characters from a sentence and make it difficult to read!

What is difficult is the abreviations you are using.
I'm 68 years old and all of the younger generation words are foreign to me.
Please be explicit. English or French is OK with me.

What the keyboard challenged is trying to say is that each of your objects within the control has a border. If it is the UC borderchange event then I beleive it will be the UC container. If you change the border on a textbox within the UC does the event for the UC fire. If so then as ~V~ said chek the current active control inside the UC.

Thank you.
Now I'm closer to the solution.
I'll test with that and get back to you.

Microsoft has an interop library for controlling Excel, that's what you probably want to look at.

myworksheet.cells(2,1).value="Address :"

Is there anyway to translate this Excel program into a VB.Net one ?
The Program goes like this:
I enter 2 fields : Density & Temperture .
They will be converted and used later on to get the Coefficient , The putput is Tabel ASTM table 54-B
2 Input Boxes: in locations
I8 and J8
Box K8
=IF((J8*100)-INT(J8*100)<0.1,INT(J8*100),IF((J8*100)-INT(J8*100)<0.3,INT(J8*100)+0.2,IF((J8*100)-INT(J8*100)<0.5,INT(J8*100)+0.4,IF((J8*100)-INT(J8*100)<0.7,INT(J8*100)+0.6,IF((J8*100)-INT(J8*100)<0.9,INT(J8*100)+0.8,(INT(J8*100)+1))))))*10
Box L8
=IF(K8<=771,(346.4228/K8^2)+(0.4388/K8),(IF(K8>=771.1,(IF(K8<=787,(2680.3206/K8^2)-0.00336312,(IF(K8>=787.1,(IF(K8<=838.49,(594.5418/K8^2),(IF(K8>=838.5,(IF(K8<=1075.5,(186.9696/K8^2)+(0.4862/K8))))))))))))))
Output Box M8
=(ROUND(EXP(-L8*(I8-15)-0.8*(L8^2)*((I8-15)^2)),4))

You have an excel formula and you want to write a VB program that does the same ? Seems pretty simple to me, do you know any VB ? If you don't and you have no intention to learn, it could save you some grief to just pay someone to write this for you.

Hy,
I just wanted VB.Net program or formula that do the same job as the Excel one. That's all. I couldn't read well the Excel formula & I need to use i in VB.Net.
