vb.net: when i click into a datagrid, the text becomes blue, the background gray, a cursor appears, and formatting for that cell disappears.
but i want nothing at all to happen, when i click in a cell. no cursor, no change of color. how can i do that?
|
|
|
|
|
one possible solution would be to capture the datagrid's mouse up event and then select some other control such as a blank label or soemthing
<br />
Private Sub datagrid_MouseUp(ByVal sender As Object, _<br />
ByVal e As System.Windows.Forms.MouseEventArgs) Handles dtgCategory.MouseUp<br />
label.Select()<br />
End Sub<br />

thanks, didn't think about that myself.
i thought about something like overriding the selection of the grid cell somehow, but i didn't know, how to do.
but this should be fine for me. thanks.

I've repaired ur project. Couldn't figure out why it didnt work. SO I created a new project I started to paste ur code. I got it working.
You still have some problems to correct to it but I guess u know it already and I dont think that u'll have any problem to correct them.
I can send you a zip with the new project on ur email address.
You can respond at: ludo.deraed@fox.com
I'll explain you in details why it could't show the components.

Does anybody knows how to play an swf file inside a .NET form.
I tried to use the flash ocx component but it says failed to load activeX.
Is there any other means?
Thanks in advance,
Phil
|
|
|
|
|
You could use a webbrowser control and navigate to the swf file
Add the WebBrowser control to your form and call the navigate method from code
i.e. WebBrowser1.navigate("pathto swf").
Should work as long as a working swf player is registered with IE.

All you have to do is handle the KeyDown event of the TextBox. I have no idea what you want to do with the Ascii value, so...
Private Sub TextBox1_KeyDown(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
' The keycode is in e.Keycode.
Console.WriteLine("KeyCode value: " & e.KeyCode )
End Sub

I have a form which when loaded adds x number of checkboxes. In the function i have written to add the checkboxes i have included the folling lines
ACheckBox.Tag = Index
' Index being the number of the current Checkbox
AddHandler aCheckBox.CheckChanged, AddressOf MyClickHandler
How in the 'MyClickHandler' sub will i be able to find the index of the aCheckBox that was clicked ?
Thanks for any help 
I really do need help..... all this computer stuff is way over my head !!
|
|
|
|
|
Sub MyClickHandler(sender as object,e as system.eventargs)
sender.tag ' checkbox that was checked.
end sub
|
|
|
|
|
To expand on the other posters answer... When you create the checkboxs in your code, set the Tag property of each CheckBox to the number you want. You can then look at that property in the ClickHandler code to figure out which one was clicked.

Hello,
I have some strings which I want to replace them with single quotes so that I can use them as arguments that are passed to a sql query.
Example, string variable Name:
"Peter John"
Should be replaced with single quotes
'Peter John'
so name should contain only 'Peter John'
Is there any possible way to do this.
I have tried doing the following:
name.replace(34, 39) 'unicode characters, did seem to work.
name.replace(" "" ","'") 'Not work either
I have been told to use the escape characters:
name.replace('\"','\'')' Syntax error expression expected
Many thanks for any help,
Steve

|

please tell us why u intend to do this

As you asked in the C# forum, you got C# code. You can't use escape sequences in VB.

b { font-weight: normal; }

Not totaly sure I understand your request, but if the value of 'name' variable contains the double quote, name.replace("""","'") should work.
