Sorry I did leave out "minimal impact". I am not trying to change existing applications. Each one of our forms inherits from a base form. My intention was to insert calls to my new class into this base form and then any existing application would not need one line of code altered...
you are allowed to change the background color of a disabled control but not the foreground color. that's my problem...
a little costly and slow to be creating a 2nd set of controls of a readonly mode of an application so I would rule that possibility out...

Well I thought about it a bit but I'm afraid I'm out of ideas!

I have a general question about how to work on subsets of datasets
I have a dataset that has data. I want to operate on only part of that dataset. So I create a dataview and filter the datatable into it. Then I create a datagridview from the dataview. Then I perform my operations on the datagridview.
This works, but I guess it seems kind of strange -- datagridviews seem to have an entirely different purpose. Does it make sense to do data analysis on a datagridview, or is there a better approach for me?
Thanks!

I am confused...I am trying to learn how to send a query to a oracle database (i am connected to it) I am just doing a test to retrieve a piece of data from this database and displaying this info on a label... Its not working  Im having a hard time because Oracle needs a password to be sent to access the data. Does anyone know the format for doing this? Any help would be appreciated.
Thanks
Erica

Can u tell in detail how are you connecting to the DB and what is the connection object u are using...
The basic idea is
We define the connection object
We define the connection string....with the DB password
Open the connection
Then use the connection object whenever you have to access any data
Good luck

Hi All! I'm looking for a way to convert xml data to Tiff format in VB6. Previously I'm using a III'rd party component to generate PDF file. But the problem is that, it is taking too much time to generate the PDF Files. What I'm looking for is a way to generate Tiff file or any other common format out of the XML in VB6 preferably through code or some free component.
Thanks in advance

The way of VB6 - get components to do the work. GDI+ will write a tiff, if you want to create your XML in a bitmap format ( and I can't imagine why ), then just draw the string on a bitmap and save it. VB.NET has tiff support built in, VB6 sucks, and probably does not, but the XML part isn't your problem, just the saving in different image formats is. Surely there's tons of components that will help VB6 save jpg/tiff/etc ?

hi,
how can hide some textbox some time and this moment show another textbox ,after the time finish show again first textbox in form
|
|
|
|

You can use the Timer Control for this purpose set its interval property then use visible property of the textboxes to hide or show them on screen. I am assuming Textboxes are already on your form and some of them with their visible property set to false. If you want to add Textboxed dynamically then you have to make an object of it and after seeting its properties add it in the control collection of your form.

I've got an axwebbrowser object embedded on a standard windows form within a VB.Net (vs2003) application. Everything works fine until it tries to link to a pdf file. I get script errors and a blank screen. The strange thing is that if I point it to a pdf file on my hard disk eg. c:\example.pdf it works fine and the pdf displays ok. It just seems to be pdf files from the intenet that it has a problem with.
Anyone had a similar problem ?
Cheers.

Hi To all ,
I didnt find help for this so i am posting inthis forum .
Now , i want to enter text when i click on grey area whether it is on any row or particular colum dynamically like entering text into textbox for datagridview .I dont know whether this feature supports to datagridview .
After running the form(design Mode for my application ),Actually i am creating an instance of datagridview and placing at any point. Then he clicks a Row Header Cell or ColumHeader cell Which are in GREY color and he writes Text (Empno ) at that instance like entering text into textbox .I dont want to give the user to enter text in cells only he can enter text for header (Both row and column ). This is all in design mode .
(In run Mode for my application )If we open that particular Form again , He cannot change the text of Column and row Headers but he can enter text in cells .This is the way i have to design the datagridview .
(For saving and retrieving) , i want to save all this data which is in Datagridview in an XML file and i have to retrieve the same .

I am using Adodb recordset to get the count of the total number of rows reterieved from a query?
In vb6 we can get this easily with
myrcd.recordcount
but if I use the above statement in vb.net 2003 it return -1.
Can we get count from reader without putting this in a loop to count every single record?
Thanks In advance

Why are you starting VB6 ? VB.NET is free, and VB6 is a dead, unsupported language.

hi all,

I am still confused on what you are trying to accomplish. Are you wanting an index value to determine what report to print? By the way, every control has a Tag variable. You could set integer values in the tag to differentiate betten the menu items.
Cheers!
Richard
may your code be error free.
(okay, maybe two lines.)

Hi Richard

[code]
Dim mShowMenuItem As System.Windows.Forms.MenuItem
mShowMenuItem = DirectCast(sender, System.Windows.Forms.MenuItem)
mShowMenuItem.MenuItems.Clear()
Dim n, i As Integer
Dim a, b As String
s = "Select srno from cash"
com = New OleDbCommand(s, con)
con.Open()
dr = com.ExecuteReader
While dr.Read
n = dr(0)
End While
con.Close()
For i = 1 To n
s = "Select account from cash"
com = New OleDbCommand(s, con)
con.Open()
dr = com.ExecuteReader
While dr.Read()
a = dr(0)
Dim mSubSubMenuItem As System.Windows.Forms.MenuItem
mSubSubMenuItem = New System.Windows.Forms.MenuItem
mSubSubMenuItem.Index = i
mSubSubMenuItem.Text = a
mSubSubMenuItem.Enabled = True
mSubSubMenuItem.Visible = True
AddHandler mSubSubMenuItem.Click, AddressOf MenuClickHandler
mShowMenuItem.MenuItems.Add(mSubSubMenuItem)
i = i + 1
End While
con.Close()
Next
this will generate menus
Public Sub MenuClickHandler(ByVal Sender As Object, ByVal e As System.EventArgs)
'Don't know wt to write here
End Sub
