owh.....hmmm....is it maybe because i input the wrong data type?

OleDbException is generic for lots of things. Depends on what you were trying to do and what your code looks like.

one more thing....what exactly insertcommand.executenonquery do?
|
|
|
|

Assuming that "insertcommand" refers to an instance that has been initialized as an OleDbCommand object that has its command text set to an "INSERT INTO ..." statement, then insertcommand.ExecuteNonQuery() should execute the command without returning the affected records.

I have developed a data entry form and set the tab order, but in entering data, it seems more intuitive to use the Enter Key than the Tab to change the focus to the next text box. Is there a way to make these two keys work the same way in this application?
Thanks!

you could trap for keycode of 13

Thanks!
I'm new at this.
I assume that key code 13 is the Enter key, but how do I "trap" it?
Thanks Again!

You "trap" it by adding this code in the KeyDown event
If e.KeyCode = Keys.Enter Then
End If

I don't know why, but KeyPress tends to work better for this (for me, at least) than KeyDown.
' include whatever controls you want to have this functionality
Private Sub KeyPressed(ByVal sender As Object, ByVal e As KeyPressEventArgs) Handles _
TextBox1.KeyPress, TextBox2.KeyPress, TextBox3.KeyPress, TextBox4.KeyPress
If e.KeyChar = ChrW(13) Then
ProcessTabKey(True)
e.Handled = True
End If
End Sub
This isn't the only way to do what you want, but it works.

Hi ,,,
I have made an application which uses CrystalReport 8.5 Viewer(that comes with .net setup). I made a setup so that the client can view the reports. I read in the help file that to include all the files for CrstalDecisions we need to include 3 Msm files i.e. merge modules in the setup. They are MANAGED_ENU.MSM, DATABASE_ACCESS_ENU.MSM, REGWIZ.MSM. I couldnt find MANAGED_ENU.MSM, instead of it I included MANAGED.MSM. I also couldnt find DATABASE_ACCESS_ENU.MSM, instead of it I included DATABASE_ACCESS.MSM. They contain the files needed for CrystalDecisions. But when I included REGWIZ.MSM , it doesnt show me any files in the list(When we see the file list in Mergemodule by including it in the setup). It shows empty list. As per the help file, REGWIZ.MSM contains a file called KEYCODEV2.DLL. But its missing in the MSM FILE. And the error I am getting when I try to open the report at clients place is "INVALID KEY CODE". So where should I find these three files so that I can include it in the project. I searched it on the net but could nt get any of these files.
What are the other options for this error???
Thanks Tasnim

Hi
I have prepared an application in VB.Net, i have used Crystal Report 9 to make Reports. Component on VB.Net Form i am using is the one which comes together with the VS.Net, i.e of Crystal Report 8.5. So when i make setup (i include all the necessary files like Crystal Descision files) setup installs the product successfully but when i run the project it gives error of KeycodeV2.dll not found, but it is there in the desired path.
Can anyone help me for the problem, it would be really nice as only this report portion is left.
Thanks for going through

Did you get a licence key for Crystal Reports? I had this problem, and if I remember correctly, to fix it you get a (free) licence key from Crystal Decisions, and stuff that into the Serial Key (?) property for the Crystal merge module in your setup.
It's something like that anyway, I mentally purge myself of Crystal related things as far as possible
