Hello,
I have got a question regarding the textbox-control.
Is it possible to resize the input area of a textbox (in a inherited class) by keeping the controls width and height unchanged?
I want place a button right next to the input area. If the user presses the button (or the F4-Key on his keyboard) the textbox should open a Lookup-Form (this is not the problem). This can easily be done by adding a button-control to the ControlCollection, adding a handler to the button's Click-Event and overriding the PreProcessMessage-Function for checking the F4-Key. But I couldn't find out, how to change the size of the input-area, so that the button and the textbox doesn't overlap eachother.
I tried to write an User-control. This works nice, but the User-Control hides all of the Textbox-Properties which I need. So I had to write some kind of wrapper to make them visible again - and this is not really nice.
I would be pleased if someone could give me a hint.
PS: I'm sorry for my bad english-skills.

Your best bet is to do what you're doing. The textbox is a nasty control, very difficult to derive from b/c it paints itself outside of it's paint event.

Hi Christian,
thanks for your reply. I've wondered why overriding the OnPaint-method does not do anything. Even setting the eventargs to nothing doesnt prevent the control from painting.
I've got two fuether Questons:
- Could you (or someone else) give me a link to the "internals" of the Textbox-Control (MSDN just explain how to make use of the properties, painting is not explained there).
- The Textbox-Control has a nice sizing feature: If Multiline is disabled, the control's height can't be set by Drag'n Drop in Design-Mode. I would like to have such a feature in my UserControl too. How can this be done?

hi,
i'm using VS2008 working on windows application vb.net...
i want to sending data on my listbox through comm RS232, here my code,
dim a as byte
a = convert.tobyte(listbox1.items(3))
the data in that listbox is "85" for example.. then after sending it to comm, the application that receive it show "38 35" where it is in hex.. i'm confusing now why it didn't show "55" where is the correct answer in hex..
plz help me i'm try to do almost two weeks..

You can't convert a string to a byte. You can convert a char to a byte, but a string is a byte/char array
85 is two characters - 8 and 5. 8 is 38 in hex, and 5 is 35. This is made all the more clear by 35 being 3 less than 38. If you want to convert a number to hex, use a ToString overload, you're looking in the wrong place and confusing yourself.

If you have a decimal number string to convert to a byte, you should use the Byte.Parse method. You can also convert hexadecimal numbers if you use one of the overloads that takes a Globalization something or other flag.

Can we have a static block in VB.net just like we have in java ?
If yes can you please provide me a syntax for it !
|
|

Your question gives the answer. A static method or property in VB is called Shared.

A 'static' initializer block in Java is really just a static constructor.
So...
class Foo
{
static
{
...
}
}
just converts to:
Friend Class Foo
Shared Sub New()
...
End Sub
End Class

Hi folks
Hope you can give me a hint, I've spent 3 days trying to sort this out!
Working in visual studio 2005 proff, with .net framework 3.5.
Application has got various forms that are children of a parent.
All are loading, adding, saving and deleting fine. Apart from one.
I've tried an insert and made it a scaler. I've tried all sorts and just cannot get this to save.
It will do MemberID (Primary key) ClientsMare, and clientsid(fk) but clientsname, maresname, percentage no go Here's the Public Sub for Saving.
Public Sub SaveMember()
Adding = False
Deleting = False
lblMemberID.Text = CurrentMemberID
Me.SyndicateMembersBindingSource.EndEdit();
Me.SyndicateMembersTableAdapter.InsertMember(CurrentSyndicateID, MaresName, CurrentMareID, CurrentPercentage, CurrentClient)
Me.SyndicateMembersTableAdapter.Update(Me.DachelDataSet.Tables("SyndicateMembers"))
Welcome.btnSave.Enabled = False
'ONCE FINISHED NEED TO MAKE THIS FILL TO A FILLBYSYNDICATEID
Me.SyndicateMembersTableAdapter.FillByMember(Me.DachelDataSet.SyndicateMembers, CurrentMemberID)
Welcome.btnAdd.Enabled = True
End Sub
any ideas why I'm having this prob on just one form?
Thanks

Because you're using the nasty built in stuff, you're just plain hoping it magically writes the right SQL for you. Write your own SQL and then you'll have control over what it does.

Rotation of what?

What do you mean exactly with "failed"?

Not likely unless you get a lot more specific...
Despite everything, the person most likely to be fooling you next is yourself.

If you want to rotate an image, then the grapics object as a rotation transform. But, as others ave said, we're left guessing waht you want as you give us nothing to work on.

here, i just want to know how i'm supposed to rotate the map / object in vb.net?..what code should i use..
|

The code that draws the map uses a graphics object. Set it's rotation transform first, and reset it after.
