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

Hello,
when i play a sound file like mp3 or wav with MediaPlayer or anything like
this, i would like to get the volume level of the sound card in real time.
The data is then sent to the serial port. How do i get this data. I tried to
find some samples in msdn or internet but i couldn t find any useful code.
There is the winmm.dll which supports calls to waveIn and waveOut but all
the samples use them to set or get the master volume. That is not what i
need. I thought i found a sample in msdn, but this doesnt work. Is directX a
way to solve this problem?
Can anybody
help me??

Do you want the "volume level" or the sampled peaks of the output going to the speakers?
Volume is simple, you've already found the code for it.
Sampling the output is a whole other story. Now you have to consider getting the output of 1 to 8 speakers. This sampling can occur very fast, but can your serial port implementation keep up with the rate of data you want to transmit? How fast are you looking at sending data out the serial port?
You might want to look at this[^] link for a sample on MSDN.

1. You can insert the RTF code using SelectRTF, you'd have get the basic code from wordpad, then modify it a bit.
2. Also you can (although I've not been able to get it to work myself), create a word object and add a table, see the newsgroups for example.
However, even if you get point 1 working there is a problem.
Tables cells don't word wrap in the richtextbox.
I've been looking for a solution to this was a day or two.
I've just been looking at the OLE Object example on this site, I thought I might be able to insert HTML, but I can't get it to work. Even if I could I'd then have a problem with resizing columns.
I've just about ready to give up.

Hy All.
I have following problem.
"Run time error 426. One form MDI only admitted"
The code allows to print from one form which shows a print preview and, after that, it's possible to click on print commandbutton:
Private sub cmdPrint_click()
gprint = True
Call frmMain.ActiveForm.printText
Unload me
End Sub
Main form is frmMain (MDIForm1). I don't understand why there are two MDI form loaded, as seems to say message error.
Elsewhere, in another similar step, I got same message (in this step I load an image into the document.
The code is following:
Private InsertImage_click()
Clipboard.clear
clipboard.setdata Picture1.Picture
SendMessage frmMain.ActiveForm.Text1.hwnd WM_Paste, 0, 0
Unload Me
End Sub
I suspect it's wrong "frmMain".
Who can help me?
Thanks in advance.

Hi,
I am trying to create a SPARSE file that reflects the size of an original file. for excample, I would like to create a 33gb(Logical) file that is physically only a few bytes.
I am able to create a 0(logical/physical) byte file only with the following code but I can't seem to get the Logical value assigned. Could someone tel me what I'm missing?

First, your declaration for DeviceIOControl is wrong. Your passing all variable in ByVal, but some of the parameters must be passed in ByRef. This is because DeviceIOControl is looking for the address of the variable, not it's value. The parameters that start with 'lp' are actually long pointers, which represent a 32-bit address, not a value. This is where you pass by reference.
Public Declare Function DeviceIoControl Lib "kernel32" ( _
ByVal hDevice As Long, _
ByVal dwIoControlCode As Long, _
ByRef lpInBuffer As String, _
ByVal nInBufferSize As Long, _
ByRef lpOutBuffer As String, _
ByVal nOutBufferSize As Long, _
ByRef lpBytesReturned As Long, _
ByVal lpOverlapped As String) As Long
Try that and see what happens...
