Hello Vijay,

Define a variable in child form of type MDIForm.

Dim _mrm As MainForm

Now define a function in Child form which takes an argument of type MDIForm. For example:

Public Sub parentmin(ByVal mainform As MainForm)

_mrm = mainform

Me.Show()

End Sub

Set the following code in the LostFocus() event of the childform

Private Sub Form1_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.LostFocus

_mrm.Focus()

_mrm.WindowState = FormWindowState.Minimized

End Sub

Now From MDIForm, you should call the Child form in the following manner(Lets say on menu button click):

Dim frm As New Form1
frm.parentmin(Me)

I believe this should help.

Regards,

Allen

Not sure of exactly what you are looking for here.

You can always just open an XML file in word.

What is it that you are trying to do?

You want the data formatted when you open it?

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

Convert Vector File to image

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

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 "")

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?
