Greetings:
I am back on this question again. My work around did not work. 
Let me explain what I am trying to ask here:
I have a 'blank' excel workbook already open which I see in my taskbar. Now I want to open an excel file in this blank Excel which is already open.
If I do "Dim xlApp As New Excel.Application", this will open a new Excel file. If I do "Dim xlApp As Excel.Application", this will cause "Null Reference ..." thing
So, how can I reference the already open excel work book or how can I open the existing excel file in already open excel workbook?
Thanks.

I am trying to decode a mp3 to wav using Lame.exe. The wav file gets created but, I am having problems trying to get the percentage done to show on a progressbar and the current % in a label.
After trying for about a week now, I want to go a differerent way. Can anyone point me to a site that has a DLL and sample code in VB 8or9? It seems to me that the "MP3 to Wav" subject does not exist in the VB world. I already been to a multitude of sites and 99% of them deal in C++ or DirectDraw which I do not want because converting C++ to VB has a lot of problems, especially (SizeOf) which has no equal in VB. There are a lot more, but that is getting off the subject.
THNX for any help in advance.

You have two options. The first is to use a library, like this: DLL To Decode MP3 To WAV/PCM. The second is to manually parse the MP3 file format and write the WAV file yourself
FYI: SizeOf does indeed have an equivalent. In classic VB, you could have used Len. Nowadays, you can use System.Runtime.InteropServices.Marshal.SizeOf

I already have this...It does not compile on my machine. I had to upgrade it to VS 2008 and in doing so, it displayed a crap load of errors. So I deleted it from my machine. I tried the Marshal.SizeOf and it still didnt work. Speaking of things that are not working, when I try to add the wmp.dll to my toolbox, I get ( dllRegisterServer in wmp.dll did not Load ) or something to that effect. I know it does not load in the Express Editions, but Im using VS 2008 Pro. It might be the VS install did not install quite correctly. I might have to uninstall it and do a complete install all over again.
THNX anyway for your time and patience.

I had this problem too.
To bypass i used the app.config to do the hibernate configuration.
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate"/>
</configSections>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
<session-factory>
...
</session-factory>
</hibernate-configuration>
</configuration>

Develop a menu based application which provides the facility to convert temperature and length from one unit to another.
Running the application will display the main “Form”, this form will have a menu with the caption “File” there will be two “submenus” under this menu, with the caption “Temperature” and “Length” (as shown below)
Clicking on “Temperature” will display another form with the caption “Temperature”. (as shown below). Here temperature will be entered in “Celsius”, and then unit of resulting value will be specified through two radio buttons. Clicking the “Compute” button will cause the entered value, converted to the unit specified through radio buttons. E.g. if user enters 12, then selects “Kelvin” radio button, then after clicking “Compute” the result will be calculated by converting the “Celsius” to Kelvin.
The formulae used for conversion are as follows:
C = (F - 32) x 5/9
K = C + 273
F = (C x 9/5) + 32
Similarly Length converter will convert the length in “Kilometers” to “Meters” and “Centimeters” e.g. if you enter “20” and select “Meter” radio button, then after clicking the “Compute” button will display the result by converting 20 to “Meter” unit.
Hint:
1 KM = 1000 M
1 M = 100 CM

A few points:
1 - a Win32 app is an app written in C++ without MFC. You can't use VB.NET for that
2 - This is obviously homework. you have two choices here, they are, do your own homework, and ask specific questions as you get stuck, or, pay someone to write it for you/pray you find someone stupid enough to write it for you for free. If you don't do your own homework, you will eventually fail your course. The fact is, the world does NOT need another temperature conversion program, the task is designed to build your programming skills. If you don't learn how to do this, how will you approach the project you get given next, which builds on those skills.
I suggest you either do some research, write some code, and ask only *specific* questions ( and in the right forum ), or you approach your teacher for either help, or advice on how to transfer to an arts course.

Point 1. You are asking people how to write a program, so presumably you think that they are reasonably clever? Why on earth do you think that

would be necessary.
Point 2. Unless you are obliged to by the specification, you should not put your conversion menu options in the File main menu. Believe it or not the File menu is supposed to be for File related actions, and, by convention, Exiting the application.

actually the hint is wrong, it should have been:
1 km = 1000 m
1 m = 100 cm
The International System[^] standardizes units (m for meter, M for molar), prefixes (k for 1000, c for 0.01, there is no C). K is often used to indicate "binary kilo" or 1024 although according to IEC that should be Ki for kibi (yikes). Kilobyte[^]

That can't be right as the Kelvin[^] scale is meant to have positive values only.

erm... 0 Kelvin is absolute zero, right ? So, why can't this be right ? According to the link you provided:
[K] = [°C] + 273.15

yours is a lot better, temperatures are real numbers, not integers, and physicists are fighting to get below -273°C, so these last centigrades do matter (and cost a lot).

OK, you mean the .15 ? Well, this is obviously his homework, so that's why they kept it simple.

Hi,
I have created the table structure and added the composite primary keys to the ms-access table using VB.NET. while the control crosses the line "ADOXtable.Columns("CHARX_VALUE_COL").Properties("Nullable").Value = False", an error message raised as "Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done."
ADOXtable = New ADOX.Table
ADOXtable.Name = "ACN_CHARX_INSTANCE"
ADOXtable.Columns.Append("LOGICAL_DB_NAME", ADOX.DataTypeEnum.adVarWChar, 32)
ADOXtable.Columns.Append("DIM_NAME", ADOX.DataTypeEnum.adVarWChar, 32)
ADOXtable.Columns.Append("CHARX_NAME", ADOX.DataTypeEnum.adVarWChar, 128)
ADOXtable.Columns.Append("CHARX_TABLE", ADOX.DataTypeEnum.adVarWChar, 128)
ADOXtable.Columns.Append("CHARX_VALUE_COL", ADOX.DataTypeEnum.adVarWChar, 128)
ADOXtable.Columns.Append("VALUES_UNIQUE", ADOX.DataTypeEnum.adInteger)
ADOXtable.Columns.Append("CHARX_ORDER_COL", ADOX.DataTypeEnum.adVarWChar, 128)
ADOXtable.Columns.Append("CHARX_ORDER", ADOX.DataTypeEnum.adInteger)
ADOXtable.Columns.Append("CHARX_NUMERIC_COL", ADOX.DataTypeEnum.adVarWChar, 128)
ADOXtable.Columns.Append("BITMAP_COL", ADOX.DataTypeEnum.adVarWChar, 128)
'append tables to database
cat.Tables.Append(ADOXtable)
key1.Name = "PrimaryKey"
key1.Type = ADOX.KeyTypeEnum.adKeyPrimary
key1.Columns.Append("LOGICAL_DB_NAME")
key1.Columns.Append("DIM_NAME")
key1.Columns.Append("CHARX_NAME")
key1.Columns.Append("CHARX_TABLE")
ADOXtable.Keys.Append(key1)
ADOXtable.Columns("CHARX_VALUE_COL").Properties("Nullable").Value = False
ADOXtable.Columns("VALUES_UNIQUE").Properties("Nullable").Value = True
ADOXtable.Columns("CHARX_ORDER_COL").Properties("Nullable").Value = True
ADOXtable.Columns("CHARX_ORDER").Properties("Nullable").Value = True
ADOXtable.Columns("CHARX_NUMERIC_COL").Properties("Nullable").Value = True
ADOXtable.Columns("BITMAP_COL").Properties("Nullable").Value = True
Please provide your valuable comments.
Thanks,

I would take that you mean that you have to commit the new columns to the database before you attempt to modify them and make the column nullable.

Use the System.Cryptography namespace to do this.

I have a Parent form with multiples tables.
let's say a group box that display text from table1 and also
I have a comboBox binding to table1 inside this groupbox along with textboxes.
On addnew from the parent table, I want to click on individual AddNew button to load a child form where I can select the one record that I want to show back to the parent table. Hence the selected PK id from table1  will show in the comboBox along with its text.
Can anyone guide me and I will be greatly appreciated..
thanks

You need to hook a delegate between the child and the parent, so that you can call a method in the child form, and it runs a method in the parent form. There's plenty of articles on delegates around.

can u point me to some delegate articles since I don't know not much about delegates.
I reformulate my question...
I am using Vb.net and Sql express I have a Parent form with multiples tables for example table1, table2, etc. I have a group box that display textboxes from table1 and along a comboBox binding to table1 datasource. On Bindingaddnewitem on the parent form, I want to click on individual AddNew button to load a child form with table1 records where I can select the one record. I want to show this record back to the parent form. Hence the selected PK id of that particular record from table1 will show back in the comboBox on the parent form along with its text. I hope I make myself clear.. Can anyone give me an idea. if I use combox to select the record from table1, this can be huge. therefore I just want the one record from the child form which can be slected from a search or slelected or new added record. Can anyone guide me and I will be greatly appreciated..
Thanks

Why could you not just use a getter setter on the child form?
