yes you need to install .net 2.0 framework for any .net appln to run there is no other way to escape

You must install the .NET Framework 2.0 in order for your app to work. You do NOT have to install Visual Studio .NET, just the .NET Framework. You can download the redistributable from here[^].

How to get File's contents the txt and Doc files. so pls some one help me...
thanking you

Reading a text file is easy. There's an example here.[^]
Reading a DOC file (I'm assuming you're referring to a Word document) is not so easy. You have to use Word to open it for you. Don't even think of trying to read it directly yourself. I don't do Office Interop, so I don't have any examples to show you, but, you may want to take a look at this[^] before you start looking for an example of opening a document.

Of course note. The RichTextBox doesn't know anything about Word's file format.

You can get the text from a Word document using Office automation (Interop). But, if there is anything other than normal text in it, like tables and graphics, they won't show up in the RTB or won't show correctly.
Office automation is not something I do, so I don't have any examples to give you. But, this[^] should be a good place to start.

Private Sub BPrint_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BPrint.Click<br />
Dim frm As New FrmPrintReport 'reports<br />
Dim cr As New CRepResponsable<br />
cr.SetParameterValue(0, Val(Me.TBAccountNumber.Text))'integer<br />
cr.SetParameterValue(1, Me.TBAccountNumber.Text)'string<br />
cr.SetParameterValue(2, vbNull) 'integer<br />
cr.SetParameterValue(3, vbNull) 'string<br />
<br />
frm.CrystalReportViewer.ReportSource = cr<br />
frm.MdiParent = Me.MdiParent<br />
frm.Show()<br />
End Sub
i have the code above. i could not pass a null parameter, to the crystal reports. i will have an empty report  i tried vbnull.null and vbnull.empty same result.
but if I put
cr.SetParameterValue(2, Val(Me.TBSubAccount.Text))) 'integer 'not null<br />
cr.SetParameterValue(3, Me.TBSubAccount.Text) 'string 'not null
the report display the values.
here is the select expert formula (CR):
{CUSTOMERS.SUB_ACCOUNT_NUMBER} = {?SubAccount_String} and<br />
{ecole.serial} = {?AccountNumber} and<br />
{CUSTOMERS.ACCOUNT_NUMBER} = {?AccountNumber_String} and<br />
{ecole.sub_account} = {?SubAccount}
How could i pass a null parameter?

Did you include in your install, or at least install seperately, Crystal Reports?

You can use the Printer object.

Could u pls send me the source code?

I haven't, anyway, using the Printer object is fairly simple.

I was aware of this possibility, what I don't get is, why would you do it this way ? How does this create a different object to the one in the VB toolbox ?

Hi all,
I am trying to assign values to my array but i got an error [Object variable or With block variable not set.] May i know where i have gone wrong. Below is my codes. I hope you could assist me.
Thanks!!
Dim d As Integer = 1
Dim seq1 As Integer
Dim seq2 As Integer
Dim strseq1 As String
Dim strseq2 As String
seq1 = tb_seq1.Text.Length
seq2 = tb_seq2.Text.Length
strseq1 = tb_seq1.Text
strseq2 = tb_seq2.Text
'Loop to create array
Dim i, j As Integer
Dim F As Array
For i = 0 To seq1 - 1
F(i, 0) = d * i
Next
For j = 0 To seq2 - 1
F(0, j) = d * j
Next

someone_blank wrote: Dim F As Array
F = Nothing at this point
someone_blank wrote: F(i, 0) = d * i
So this will blow up.
You need to create the array with new. You'd do better to create an int array, I'd never create an instance of the Array class, that sucks. ArrayList, or List if you have VB 2005, is even better.

Hi Christian,
Thank you very much for your help.

As stated by Chris, you have to use new to create instances of the arrays. Moreover, it seems you have to use jagged arrays, since, I think, seq1, seq2 may hold different values. Look at the following MSDN sample [^]

Hello all!
i am unable to load .dsr(designer) files in vb6-Sp6.
Is it necessary to install crystal reports on my machine to work with .dsr files.
When I run VB6 and try to start a new data project I get an error to refer to datarpt.log for details - this is what the log says:
Line 2: Class {78E93846-85FD-11D0-8487-00A0C90DC8A9} of control DataReport1 was not a loaded control class.
Line 0: The file C:\bern\visbas60\Template\Projects\DataRpt.Dsr could not be loaded.
It's VB6-SP6 (brand new fresh install) - Windows XP
Any ideas?
Plz Help
Thanks!

Without installing Crystal Reports, how do you expect to edit one of it's Designer files?
That's the problem you're running into. Kind of like trying to open a Word document on a machine that doesn't have Word installed on it.

I am having trouble getting VB to interact with a MySQL server, which was setup for the purpose of keeping track of points for members of a group. The application is to display a DataGridView of an already created table which is on the MySQL server. The members would edit the table on the DataGridView, and Add or Remove a member based on a button command.
What I have read is that, by using XML, it is possible to simply connect to the database, collect the table required to display, and then disconnect (also for updating the altered data). However, since I am unable to connect to the database, the single-form layout which I had designed doesn't work. I am unable to get this to work, and have tried for weeks.
I am very lost and slightly frustrated at this. I have read every online tutorial which I can find, even other forums, etc. And still...nothing  Any help will be greatly appreciated.
