Hello,
You can use the following code to bind the picture in an Picture box on a button click.
<br />
Dim fod As New OpenFileDialog<br />
fod.Filter = "JPG|*.jpg|BMP|*.bmp|All Files|*.*"<br />
Dim dr As DialogResult<br />
dr = fod.ShowDialog()<br />
If dr = Windows.Forms.DialogResult.OK Then<br />
<br />
PictureBox1.SizeMode = PictureBoxSizeMode.StretchImage<br />
PictureBox1.Load(fod.FileName)<br />
<br />
End If<br />
If you have path of the picture in a string variable, you can pass the file name to the Load()
method of the PictureBox.
I hope this helps.

Allen

How can i set day notes in calender using vb.net.which control i want to use.
|
|
|
|
|
A MonthCalendar control maybe?? Its in the ToolBox under the "All Windows Forms" tab.
As for typing in notes, you'll have to provide that functionality, plus some way to save the notes and associate them with a date/time.

Hi guys and ladies,
I created a custom control "ExtendedButton" that "Inherits System.Windows.Forms.Button", because I need to apply a rotation to this object.
I'm trying to use the overridable "OnPaint" sub but I cannot apply this rotation to the object, that's because I'm quite a newbie in VB.NET
My question is: anyone could me give some hints about adding rotation to an object like a BUTTON? Where I must look for info, exactly (do not answer me on MSDN, I know)? I don't wanna spend my youth in reading that brick-book ... if someone could give me a step-by-step procedure on what methods override and where to find them, it will be enough.
Thanks

Inheriting from Button isn't going to let you do this. The Button class will accept a click anywhere in the box that contains the image you draw.
You're going to have to implement this thing from scratch, to include all the properties to support how you want the button to be draw, including rotation, font size, text, alignment, ... You're also going to have to write all the drawing code, including rotation, and all the hit test code to test for mouse hovering over the button and click on the button image itself.
No matter what rotation you pick for the button, the control's drawing surface is always going to be an orthogonal (?) rectangle.

You'll be spending that month doing it anyway. You have to understand controls very well, hit testing, GDI+ drawing, and have good planning skills.

No, it's not enough. You're basically writing an entire control from scratch. There is no step-by-step procedure. This is going to take a LOT of work and is not something that can be described in a few forum posts.

Hi... sorry for posting it here.
If IsNull(c_SignedEmployee) = False Then<br />
dtpEmployeeSigned.Value = c_SignedEmployee.Value<br />
Else<br />
dtpEmployeeSigned.Value = DateTime.Now<br />
End If
this is a code snippet i a using...
NOW
when i try to do the same with a new column it does not show up (Like with the c_SignedEmployee it shows up if you hit Ctrl+Space)
It doesn't seem to be picking it up???
What to do?

Never mind... It is working now 
Dont ask me what i did... i have no idea.
It seems that if you wait long enough... it will eventually pick up the new column in the table and you are able to work with it then.
Funny that.

Hi JoeSharp
thanks for the suggestion
i am not that great in OOPS way... can you please send me a sample code
|

hi
a little example
Public Class MyControl
Inherits System.Windows.Forms.UserControl
Protected Overrides Sub OnMouseWheel(ByVal e As System.Windows.Forms.MouseEventArgs)
If e.Delta <> 0 Then 'has wheel been moved?
'The .NET docs suggest that e.Delta returns the actual number of notches
'the mouse wheel has been rotated, but in actuality each roll of the mouse wheel
'returns a value of +/- 120 (depending on the direction of rotation).
'120 is actually a system constant, and therefore there is a possibility that it could
'change to allow for higher-resolution mouse wheels.
'check out <http: msdn.microsoft.com="" library="" en-us="" winui="" windowsuserinterface="" userinput="" mouseinput="" mouseinputreference="" mouseinputmessages="" wm_mousewheel.asp="">
'for more information
Dim zoomIn As Boolean = (e.Delta < 0)
End Sub
Protected Overrides Sub OnPaint(ByVal e As PaintEventArgs)
' Overriden Paint Methode
' Do your paint stuff in this methode, such as draw images or draw text
End Sub
End Class

Your best bet is to leave a file behind on uninstall which tells your app not to run, but I don't see how you can stop it installing.

There is a setup building utility called GNU setup... This utility as the name tels is under GNU license
One can create setup of single file/exe or can even run multiple setup... at a time... also it allows to write scripts to be written which will help u achieve what u want...
 
Good Luck

look into 'serialisation'
it isn't easy but it will do what you want
If my help was helpfull let me know, if not let me know why.
The only way we learn is by making mistaks.
|
|

I already told you, you have to write your own serializer since Control's are not serializable themselves. You'd probably user Reflection to pick out the Properties you want and ignore others. This is NOT an easy thing to do and is NOT for someone who's a beginner to tackle. This requires knowledge of Reflection and XML document generation.
The PropertyGrid will NOT do this for you.

i have created a windows service project and a deployment project to deploy the service.
i use the setup.exe created to install the service. The service installs fine and appears in services in control panel. but when i right click and start the service i get an error message 'could not start the service1 service on the local computer.
the service did not return an error. this could be an internal windows error or an internal service error.'
so then i tried running the service from program files and i get another error message saying 'cannot start the service from a command line or debugger. a windows services must first be installed (using installutil.exe) and then started with the server explorer or windows servce administrative tool.
is there anything i need to change to get this to work.
