Data form text file: 000189,380661,SUPERSTAR VIRGO,410081,0813,2.200,5.76,12.67

I have the above code which sucessfully place data extracted from a Coma delimited text file in Column 1-8 of a ListView which have 12 ColumnHeader.

Problem:
How can i specify the column of the data to be display in?

E.g. Puting myObjectsFromFile.getObject(i + 1).Second in the 12th column instead of the 2nd, the myObjectsFromFile.getObject(i + 1).Third in the 9th column instead of 3rd .etc

Note: Juz a sample break down of what i need to do as my actuall requirement is slightly mroe complex

Is there any build-in function of Visual Basic .NET that lets me extract the dates from a GregorianCalender based on a given weeknumber of a given year?

For instance, extracting what dates belong to week 19(as an example) of a given year?

Thanks in advance.

How to select a RadioButton?

I'm using vb.net and I have 1 form with a webbrowser control on it, and one button on the form.
I have an html page I'm calling which has 2 radio buttons on it and a textbox.

I can fill in the textbox by going...
AxWebBrowser1.Document.Forms(0)("username").Value = "myusername"

My problem is, I'd like to select a radio button depending on its value...
How could I do that? I'd like to be able to select a radio button based on its value if at all possible....
I found a page on HTML Document Object Modeling here...http://www.w3schools.com/htmldom/dom_obj_radio.asp but cant quite get it figured out. Dead | X|

Thanks for any help! Big Grin | :-D

----------------------------------------------------------------------------
Heres My current code

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click<br />
   Dim Choice As String<br />
   Choice =  2<br />
<br />
   If Choice = 1 Then<br />
       AxWebBrowser1.Document.forms(0).radiobutton.value(1) = checked<br />
   ElseIf Choice = 2 Then<br />
       AxWebBrowser1.Document.forms(0).radiobutton.value(2) = checked<br />
   End If<br />
End Sub

-------------------------------------------------------------
Here's the body of the page I'm using

<body> <br />
<form name="form1" method="post" action=""> <br />
   <input name="radiobutton" type="radio" value="1"> <br />
    <br> <br />
   <input name="radiobutton" type="radio" value="2"> <br />

   <input name="username" type="text" id="username"> <br />

Disappointed with Graphics Speed

I am writing a routine which will display part of a jpeg image (say 3500x2000 pixels) in a PictureBox (size 1000x700 pixels) and then allow the user to scroll around the image by using the mouse (image scrolls whenever the right mouse button is pressed and the mouse is moved).
I am using Graphics.DrawImage to redraw the scrolled image.

gphpicbox.DrawImage(picturebox1.Image, New Rectangle(0,0, _
picturebox1.Width, _
picturebox1.Height), _
New Rectangle(intrelmoveX, intRelMoveY, _
picturebox1.Width, _
picturebox1.Height), graphicsunit.Pixel)

My problem is it is just so slow and not at all smooth.

Is there anything I can do to improve performance?

Thanks

NagaJim

From where does the gphpicbox object come from?
If you draw the image yourself I wouldn't use the picture box control (it is only useful when you let it paint the image itsself). Make your own Control (derive from control or userControl) and override the OnPaint method. Here you can do your drawings (the Graphics object can be retrieved from the eventargs). While the mouse is moving just set the appropriate properties and call YourControl.Invalidate(). That should do it.

VB.NET & ADO - Update & Insert Problems

Hello

I suspect that this is a simple error on my part but this example may help others starting out with ADO.NET.

I'm working on a very basic Database Application. I've included the full project as an attachment in this post.

Its a very basic Form that is the front end for a database containing contact information.

The form has many fields but I've only implemented the first 4 for simplicity.

The form has 4 buttons

1-Find = user enters record ID to bring up the contact information for that record (SQL Select used)
2-New = user can create a new record (SQL Insert used)
3-Save = user saves current record (updated or new- SQL Update or insert used)
4-Delete = Record deleted

I have used an access DB for simplicity but will need to use MySql or MS SQL for end project. Amen.mdb is included with project.

Parts That Work

1-Find Works OK
2-New Works OK until Save

Parts that Don't work

3 - Save - Insert only inserts the first 2 fields in the database! ie name & contact, phone & mobile don't get inserted! -
I don't understand this as the code seems OK
Update doesn't work at all - it causes an unhandled exception in the cmdUpdate part of my code.

The project was written in VS.NET 2003

Any Help greatly appreciated

Tino

I try to download your zip file, when it complete I could not open it. The message said that your zip file is not a valid archive. You can send me an e-mail to kanel@scn.online.com.kh or you can post the code of Find record and the code Save record. Because I want to compare what is the difference between the working code and that you code that you have a problem.

Zip and Unzip from VB.Net

I've seen the C#/J# article to handle this, but does anyone know of a way to do it directly from VB.Net code?

Sure you can. I dont know which article you are exactly referring to but I think you can do it nearly the same way with VB.Net.
With J# many assemblies are bundled together which mimic the behaviour of the Java libraries. These assemblies are normal .Net assemblies and can be used from any of the .Net programming languages.
So if you have J# installed you just have to reference the appropiate libraries in your project and use them as needed.

What do you mean by directly? Does the library have to be written in VB .NET? If not you can use pretty much any available managed implementation and add either a reference to a compiled assembly to your project or add another project to your existing solution. Either way you will be able to use the classes from the library no matter in which programming language they are/were written. Maybe you should have a look at the #ziplib[^].

How to Call Visual C++ .NET from Visual Basic .NET

I have what I suspect should be a simple question. I need to know how to call and pass parameters from a Visual Basic .NET program to a Visual C++ .NET program. Any help would be appreciated.

All you need to do is to reference your Managed C++ assembly in your VB.NET project and call the methods as you would for VB.NET. There isn't anything different that I am aware of. You can Import the namespace(s) used by the Managed C++ to make things easier, but Intellisense should help you out by letting you know what the parameters are.

MDI non-child forms

GeneralDisorder28-Dec-04 5:28

GeneralDisorder

28-Dec-04 5:28

Hi everybody,

I've got a program that needs to pop-up a few non-child forms the moment the MDIform loads. So I'd expect to just write a sub which opens a non-child form like this:

Private Sub MakeNonChild()
Dim FormX As Form
FormX = New Form
FormX.Owner = Me
FormX.Show()
End Sub

And then call that function in the Load event of the MDIform.
The strange thing is the form pops up allright, but it's completely disabled and I can't get it enabled in any way.
I then proceeded to make a button on my MDIform which also calls the MakeNonChild method and if I use that, it works perfectly.

Does anyone have any suggestions as to why it goes wrong in the load event?

Thx in advance!

Hi....

i try to make a graphik with data shape, but that i can't make sense is...
why the first data is not loading on the graphik that i made...

for example:
Data is: Data on graphik:
Month Amount Month Amount
JANUARY 2.000.000 FEBRUARY 3.000.000
FEBRUARY 3.000.000 MARCH 3.000.000
MARCH 4.000.000

The code is:
With ADO_Merchant
.ConnectionString = "PROVIDER=MSDataShape;" & _
"Data Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source= " & App.Path & "\DataBase\db_merchant.mdb;"
.RecordSource = "SHAPE {" & _
"SELECT * FROM tbl_Nasabah} AS Parent " & _
"APPEND ({SELECT * FROM tbl_permasalahan} AS ChildMasalah " & _
"RELATE Kd_Nasabah TO Kd_Nasabah) AS ChildMasalah, " & _
"({SELECT * FROM tbl_Pendapatan WHERE Tahun='" & lbl_Tahun.Caption & "'} AS ChildPendapatan " & _
"RELATE Kd_Nasabah TO Kd_Nasabah) AS ChildPendapatan, " & _
"({SELECT * FROM tbl_Merchant} AS ChildMerchant " & _
"RELATE Kd_Nasabah TO Kd_Nasabah) AS ChildMerchant"
.Refresh

Set Grid_Permasalahan.DataSource = .Recordset("ChildMasalah").UnderlyingValue
Set Grid_Pendapatan.DataSource = .Recordset("ChildPendapatan").UnderlyingValue
For i = 0 To 2
Set txt_Merchant(i).DataSource = .Recordset("ChildMerchant").UnderlyingValue
Next
Set Chart_Pendapatan.DataSource = ADO_Merchant.Recordset("ChildPendapatan").UnderlyingValue
End With

pls anyone can show me, where the mistake is..??

touch screen (point-of-sales) user interface

StenH28-Dec-04 1:00

I’m trying to build a well designed user interface for a point of sales touch screen application. In such an application you don’t use a mouse or keyboard – all the keys are on screen. These keys change based on context and should also be user configurable. What is a good/best practice when storing, loading and displaying such screens/keyboards?

The problems faced should be quite similar in all touch screen applications with the need for a complex user interface.

I’ve searched the internet high and low to find something on this. Books, links or advice anyone? VB.NET is preferred but anything relevant is interesting.
