The same message "ConnectionString propert is readonly"
|
|
|
|
|
The setting may be marked as an application setting, set it to a user setting. This should allow you to change the setting from your code.

Same problem :
My.Settings.MyConnectionString = str
My.Settings.Save()
Error "Property MyconnectionString is readonly"
|
|
|
|

In Visual Studio
Open the solution explorer pane
under your project name you will see "My Project"
Double click
in the main pane select the settings tab
identify the conection string setting and check the scope - this should be user and NOT application.

I wonder if anyone can help me or had a similair problem.
At the moment I developed a system using VB.Net 2003 using Crystal Reports 8.5. We have now move to Crystal Reports 10. When I load up my project and then try running it, references CRAXDRT.DLL and CRVIEWERLib.DLL are not regonised. I have tried to remove and then install again. I have tried to re-register but with no luck. If I go back to 8.5, no problems.
Any ideas?

I would assume some incompatibility between Crystal Reports 10 and VS 2003. I use Crystal Reports 10 just fine on VS 2005. Maybe you should download a trial version and try using Crystal with the newer version. If that doesn't work, go up to 2008 Beta 2, which I also use.
Just for the record, I don't recommend 2008. 2005 does the same things as far as I can tell.

You have to know the resolution to do that, i.e. what ppi (pixels per inch) are you using? This value is often (inaccurately) refered to as dpi.
Then it's just a simple calculation. Just divide the pixel value by the ppi value, and you get the value in inches.

in the keypress of the textbox test if the key pressed is the "enter" key and run whatever method you want.
|
|
|
|
|
handle the keydown or keypress methode of the textbox
Private Sub TextBox1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
If e.KeyCode = Keys.Enter Then
'do something here
End If
End Sub
I thought there was an easyer way but could be that it was in JAVA don't know any more
but this does work

hi,
use following code at keypress event of textbox
If e.KeyChar = Chr(13) Then 'Chr(13) is the Enter Key
call yourProcedure()
End If

more of a dotnet syntax... 
If e.KeyChar = ControlChars.Cr Then
'call procedure
End if
|
|
|
|
|
On keypress:
if e.keychar = cchar(chrw(keys.enter)) then<br />
'do actions<br />
end if

Hi
Using VS2005 - Visual Basic
I'd like to make a control like a button, but that looks like the Play, Stop, Record, Pause, Skip Forward and Skip Backward.
I'd like to be able to resize the button, and the images must resize.
I's like to be able to set the color of the button as well as the color of the image that shows the fuction of the button.
It only needs a click event.
I'd like to be able to add it under user controls.
I'd like to be able to set the 'function'
I'd like to be able to use the control as follows:
myButton.Style = myButton.Styles.Play
myButton.Forecolor = Color.Red
myButton.Backcolor = Color.Gray
So far I have:
Opened a new project
Chose 'Windows User Control'
Placed a normal button on the form
What do I do next???

You probably are thinking that's not what I want (I know it's a ribbon control)
BUT the devoloper creats his ribbonbuttons himself (draws them, does the eventhandling,...) and that is what you want (you will need to adjust a bit but take a look at this code and you should be able to adjust it to what you want)

Thanks for your reply. I'm pretty much a novice, and battle enough with Visual Basic, so trying to cope with C# is a bit beyond me. Do you know of anything in VB?

How do I send Arguments to a form when I open it?
EG. frmMyForm.Show("MyOpenArgs")
(I know that wont work, but that's more or less what I'm looking to do)

Hi,
I prefer this way:
- create an instance of your form
- make sure the class has one or more setter properties; use these to pass
1 or more parameters
- then Show it.
An alternative is:
- give your form class a second constructor that accepts parameters
- use that constructor to create the form's instance
- now Show it.
In the special case your form needs the command line, it could
fetch that itself through the Environment class.

hi all
i need to write the events of the titlebar of the form plz tell me how can do that.
thnx
|
|
|
|
|
what events do you think are present?
|
|
|
|
|
like click event, double click event etc
|
|
|
|
|
i don't think you can trap those events... maybe some api call but vb itself doesn't seem to allow it.
