Bummer, I have used the grid extensively to fill up with data and have the user group and sort the information. Love it for that, but this is first time trying to take a virtually empty grid and grab just the selected data from it. I've tried setting the value to <> Empty, Nothing, DBNull and many other things. Their sampls show them using a grid similarly for an odering application so I'm trying now to follow the code to see if I can locate how they check for a null value in a selected row cell. I'm also looking at how the settings for the myriad of properties may be different than the default.
If any ideas pop up please let me know,
Larry

I’m having a problem shifting focus off of a command button and onto a sheet. I have a user form called CommandButtonForm that I’m using as button. ShowModal = False. Focus stays on the form in spite of the Sheets(ActiveSheet.Index).Select and Range("A1").Select statements. I need to shift focus to the sheet.
This Workbook
Option Explicit
Private Sub Workbook_SheetActivate(ByVal Sh As Object)
CommandButtonForm.Show 'commandbuttonform
Sheets(ActiveSheet.Index).Select
Range("A1").Select
End Sub

It shouldn't matter what format a digital signature is correct? I'm encrypting a file and than I have to apply a digital signature to the file.

So long as you use an appropriate signing certificate, there's no difference.

Using the .net 2.0 framework.
When encrypting files with vb, it will take vb to decrypt the files as well right? I trying to see if the windows OS will be able to open the file since I'm using MS products.

The .Net Framework is the .Net Framework: the actual language used is irrelevant. There would be no problem having your encryption program written in VB and your decryption program in C#. For that matter, your decryption program can be in C++, Fortran, Delphi, COBOL or assembly, it really does not matter.

Yeah I just read a chapter about encryption, vb uses the XOR or exclusive OR, when encrypting the file, I noticed one of its example, it will convert a character to its ascii standard and add one 1 to the standard, do the opposite with the ascii coversion, by deducting one from the the standard and convert back to its normal form, yes any windows OS will read it correctly.

Thanks in advance
How can we send these commands directly to a POS printer in vb.net
Chr(27) + Chr(112) + Chr(0) + Chr(48) + Chr(63)

First tell me how the POS printer is connected to your PC???,
is this Driver based???,
for Send custom command to your POS Printer you have to use the printer API's

Its Connected through COM port using COM2 port and the vendor gave a driver when i use that driver it prints so slow , so i have to use Generic Driver to Cut the Paper and Open Cash drawer which is also connected to the Printer.

If it's connected to the Comport, U need not to use Generic drivers, Using SerialPort class you can send your commands, just you have to know the comport settings of your POS.
Print the receipts using the POS driver, Close the Comport(Opened by Driver), Open the comport again using Your Program, send the commands what ever you want.,

After running that through Google Translate, your question doesn't make sense.
If you're looking for code to validate soemthing, you're going to have to be a lot more specific (in English) about what you're trying to validate and under what conditions. There is no generic validation code that works with everything in all situations.

I made a lil' application that tracks wht key has been pressed...
I have called api function... but it's not tracking keys like A or a , R...
It's working for Enter, backspace pretty well.....
Why it is not working for alphabets.....
<br />
Declare Function GetAsyncKeyState Lib "user32" Alias "GetAsyncKeyState" (ByVal vKey As Keys) As Integer<br />
<br />
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load<br />
<br />
<br />
End Sub<br />
<br />
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick<br />
<br />
If GetAsyncKeyState(Keys.A) > 0 Then<br />
<br />
MsgBox("A")<br />
<br />
Else<br />
End If<br />
<br />
<br />
End Sub<br />
End Class

I don't think that is the way to track the keys being pressed (with a timer?)
Should you not be hooking into the keyboard message loop?
Look at the Docs for it;
GetAsyncKeyState Function
Determines whether a key is up or down at the time the function is called, and whether the key was pressed after a previous call to GetAsyncKeyState.
Your Timer Tick is more than likely missing the keyboard event.

I have put msg box jes to chk if it's working or not....
Ma question is that y this code not working for keys A B C...
It's only working for few keys like enter, Ctrl, Escape.....
|
|
|
|
|
It doesn't work because the key goes through make/break before your Timer fires. Your timer has to fire between the key make and key break message, which will happen VERY quickly.
Seriously, this is a very bad way of see which keys were hit.
A better method would be a keyboard hook.

Yeah i kno Timer concept is not rite.....but ma focus was on keys 'A','B'....y it's not working for them..
rather works totally fine for enter....
Here some changes i made
<br />
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress<br />
<br />
If GetAsyncKeyState(Keys.Enter) > 0 Then<br />
<br />
MsgBox("Enter")<br />
<br />
Else<br />
End If<br />
<br />
End Sub
Even this is not working although it's done on Key press event....
