I asked about the cam device control and cam picture control in the wrong place. Stupid of me, I know. I've looked in alot of places. Most times they tell how to access the web cam without using the cam control devices. I want to know how to use them. Can anyone tell me how? Thanx, StephenStefl

I found some code to save a persons signature to a file. It also will load a saved Signature and display it in the panel. I want to create a report using Crystal reports. I don't know much about it. But, I want to be able to display the signature on the report. Is there a way to do this in Crystal reports? If not, do you know the best way to do this? I would like to find some code that can convert a Vector file into a image file and then put the file on the Crystal report. Any suggestions?
Thank you.

Hi,
anything you can draw to a Panel, you can turn into an image file, using
Control.DrawToBitmap() and Image.Save(). So the signature would become just another image.
I trust CryRep knows how to handle images.

You See there is one thing you should do before you post in a Forum, not only CodeProject, in any Forum or before you ask for help. at least try to make your own research first and Google

Hope this helps

hi all,
i filter a datagrid with input into a texbox. It filters fine. But how do i bring back the original data into the grid when the textbox is empty?
code below:
'This is in the textchanged of txtQS
If Not txtQS.Text.Trim = "" Then<br />
Dim dt As TMSDataSet.LASTIDNOREFFDataTable = New TMSDataSet.LASTIDNOREFFDataTable()<br />
LASTIDNOREFFTableAdapter.Fill(dt)<br />
Dim dv As DataView = New DataView(dt)<br />
dv.RowFilter = "lastmonth = " + txtQS.Text<br />
LASTIDNOREFFDataGridView.DataSource = dv<br />
LASTIDNOREFFDataGridView.Refresh()<br />
Else<br />
Me.LASTIDNOREFFTableAdapter.Fill(Me.TMSDataSet.LASTIDNOREFF)<br />
End If
Thanx.

Try setting dv.RowFilter = nothing (or it might be "")

Not successful?
Get a converter! It's far easier.

First try using Google. Then write some code. Then ask nicely and someone may help you. Just demanding how.... is not going to win you many friends.

Command for Copying file
My.Computer.FileSystem.CopyFile("C:\Source.txt", "C:\NewFolder\Dest.txt")

Thanks & Regards

Because i am doing a application on housekeeping. I need my hard disk space to be 80% full and test if my application is working therefore i need to keep copying file to my specify folder so that the disk space can be 80% full and allow my application to stop working. By using the way u told me i can only copy 1 specify file at a time only. Or is there a command whereby i am able to create dummy file with example like .ppt?

You could always create and open a text file and continue to append text to it, in a loop, until it reaches the desired size.

That's going to be a HUGE file  (don't know if notepad even opens that, have to test it as soon as I come home )
|

just put the code in a loop and add a variable to the copyto path
dim i as integer = 0
do while i < 1000
My.Computer.FileSystem.CopyFile("C:\Source.txt", "C:\NewFolder\Dest" & i & ".txt")
i+=1
loop
this will copy the same file a 1000 times
you could ofcourse check the harddisk space available and stop if it reaches 80% but I think that would take this to far if it's jut for testing purposes

A for..Next loop would be cleaner
For i As Integer = 1 to 1000
My.Computer.FileSystem.CopyFile("C:\Source.txt", "C:\NewFolder\Dest" & i & ".txt")
Next

Must be from looking at an ex-collegue's code all day (nothing but while true loops), it's driving my crazy
