DHTML Editing Control - Table Property's?

2-May-07 8:54

Put a break point in on the first line of code that you want to step through. To do this put the cursor on the line and press F9.

Then run the code. It will stop at that point, press F11 to step through each line of code and put your cursor over the variables to see what's in their values.

Cheers

to convert textbox text to single:

froma = cdec(textbox.text)

Note that if a non-numeric character (a letter or a symbol) is entered into the textbox it will cause an exception error, to get around that use a validation technique such as

if isnumeric(textbox.text) = false then<br />
messagebox.show("you did not enter a number!")<br />
textbox.focus()<br />
end if<br />

what this does is alerts the user to his/her error and forces them to correct it

now as for the step-by-step.

The step-by-step shows you what the complier is actually running, so if it never gets highlighted it never has been called

Example:

if true= true than<br />
'this code will always run<br />
else if x = 10 then<br />
'this code will never run<br />
else<br />
'this code will also never run<br />
end if<br />

Hopes this helps

hey, we are working on a project, "voice command and control" in VB.NET.
we have used SAPI 5.0. till now our project performs for getting input from any user, means everyone's "hello" is same. we are not using or matching input frequencies.
can u give me idea to generate a wave file and read it and convert it to hex which can be helpful to differentiate the input sounds of different user.
waiting for anyone's suggestions!

Basically, you're going to have to do your own research on this. This is "voice print" security technology you're talking about. Just start Googling "voice print security" and you'll come up with a bunch of products, but little in the way of research papers.

Hi all...

I'm trying to set a right click function to my app, so that when a user right click anywhere in the application Window (except on controls), it will pop up a msgbox.

I've read some articles about using context menu but I hardly understands it. Can somebody explain?

You're reading about right clicking in the designer. Yuo just want to add a context menu, google for 'context menu VB.NET'

Hi there, thanks for replying. I don't actually want context menu. I want a MsgBox to pop up when user right click ok the application. Any idea?

OK, you plainly want the mouse down message then, the trick is getting it in the non client area. I think you need to use the WndProc for that.

If you just want the message when you right click the form the following will work (just add it to the form):

<br />
    Protected Overrides Sub OnMouseClick(ByVal e As System.Windows.Forms.MouseEventArgs)<br />
        MyBase.OnMouseClick(e)<br />
<br />
        If e.Button = Windows.Forms.MouseButtons.Right Then<br />
            MessageBox.Show("You clicked the form with the right mouse button!", "My Application")<br />
        End If<br />
<br />
    End Sub<br />

Hope this helps.

Hi there, it really works on an empty form. Can you teach me on how to apply this code on other object such as picture box etc?

Re: Pop up on right click on the whole application window

how to set a corresponding color on a particular cell?

2-May-07 8:48

Just create an event handler to the same code for the MouseClick event of the control(s) in question:

<br />
Private Sub MyControls_MouseClick(sender As Object, e As MouseEventArgs) _    <br />
     Handles MyPictureBox.MouseClick, _<br />
             MyLabel.MouseClick, etc, etc<br />
<br />
     If e.Button = Windows.Forms.MouseButtons.Right Then<br />
             MessageBox.Show("You clicked the form with the right mouse button!", "My Application")<br />
<br />
     End If<br />
<br />
End Sub<br />

An easy way to do this is select the control in the desiger, open the property grid for it (F4), click the events button at the top (the one with the lightning bolt on it) and double click the event you want to create the handler for. This will create the code stub for the event handler automatically.

You can set the property CellBackColor - this will change the background color of the current cell, referred to by the current values of Row and Col properties.

Not sure about the FlexiGrid, but the ListView control allows you to modify the format of the subitems by setting ListViewItem.UseItemStyleForSubItems = False, then you just change the properties for a particular subitem to get the desired results.

There may be something similar for the FlexiGrid?

Hope this helps.

I dont know what type sample.violet is... what the CellForeColor expects is a long integer containing some RGB value. To set font color in cell(4,5), you will need to do something like:

flxgrd.row = 4
flxgrd.col = 5
flxgrd.cellforecolor = rgb(180, 180, 180)

hope this helps.
