Hello All..
I wonder how microsoft insert the date (today date) to the document.
what happen after insertion? did it just insert it or have an record of saying this particular date is inserted by Insert->Date ( autodate)
Is there any different between Insert->Date and the date we just type in like (12-10-03) ??

I would like to be able to pick a colour on a PictureBox control and make it transparent. How can I then save the image as a gif file with transparency. I have a program that draws shapes on an image in a picturebox, however when I save the image none of the shapes that I have drawn are saved. What do I need to do to achieve this. Any help is appreciated.
Jim

OK, first of all, are you drawing the shapes on the PictureBox's Graphics, or a Graphics created from the bitmap? You need to create a graphics from the bitmap using Graphics.FromImage(), and then draw on that.
About transparency, I really don't know how to do that with GIFs in GDI+. I believe the first entry in the palette is the transparent color, but I don't know how to set that with GDI+.

Thanks for your reply
In my program the PictureBox is either loaded from a file:
pictureBox.Image = Image.FromFile(dlg.FileName)
Or from a stream:
Dim binaryData(-1) As [Byte]
binaryData = Base64Utility.GetByteArray(_ImageData)
Dim ms As New MemoryStream(binaryData)
_PictureBox.Image = Image.FromStream(ms)
To draw on the PictureBox I am calling the Invalidate method which then fires the Paint event:
pictureBox.Invalidate()
In the paint event I am passing the PaintEventArgs to this Draw Sub.
Public Sub Draw(ByVal p As Pen, ByVal e As PaintEventArgs) Implements IHotspot.Draw
If _bEndIsSet Then
e.Graphics.DrawRectangle(p, New Rectangle(_ptOrigin.X, _ptOrigin.Y, (_ptEnd.X - _ptOrigin.X), (_ptEnd.Y - _ptOrigin.Y)))
e.Graphics.DrawRectangle(p, _ptEnd.X - 2, _ptEnd.Y - 2, 4, 4)
'e.Graphics.DrawString(CStr(_ptOrigin.X) & ":" & CStr(_ptOrigin.Y), New Font("arial", 8, FontStyle.Regular), Brushes.Yellow, _ptOrigin.X, _ptOrigin.Y)
End If
End Sub
So instead of using e.Graphics I should be using Graphics.FromImage() to draw on?

Correct. In VB6, you could draw on the picturebox and what you drew would show up on the image, but with VB.NET, this doesn't happen. IMO it's much better that way.

Sorry, but that struck me as very tongue-in-cheek.

I won't say it is a problem. Just that I was interested to know wheither VB.NET has a MDI template like in MFC MDI?
I have checked out VB.NET. It seems that most the stuff need to be built on scratch.
Any hints? Thanks

Create a (parent) form and set the form's IsMdiContainer property.
- <parent>.IsMdiContainer = True
Create a child form and set the child's MdiParent property to point to the parent form.

We have had multiple occurances of datasets disappering from the designer. We cannot be specific about the circumstances since we simply do not know when this will occur or under what conditions.
The .xsd and associated .vb files are still located in the source directory. The .vbproj file has references to both but is missing the following tagged lines (as an example). Restoring the tagged lines allows the code to compile correctly, but the data sets still do not show up in the designer. The implication is that we can't select the dataset and look at or modify the schema. Here is a snippet from the .vbproj with the missing lines tagged by >>>
<file
relpath="LabNfonts.vb"
="">>> DependentUpon = "LabNfonts.xsd"
SubType = "code"
>>> BuildAction = "Compile"
>>> DesignTime = "True"
>>> AutoGen = "True"
/>
<file
relpath="LabNfonts.xsd"
="" buildaction="Content">>> Generator = "MSDataSetGenerator"
>>> LastGenOutput = "LabNfonts.xsd"
/>
We are using a single data adapter and reconfiguring it to generate each data set. At execution time, the dataAdapter select, insert, delete, and update comman text is dynamically altered.
The only other way we have found to get the datasets back is to completely delete the dataset and all references to it in the MS generated code, then reconfigure the dataAdaper and regenerate the the dataset.
This is a huge waste of time, and I believe there must be s simple solution for prevention and cure of the problem.
Any insight would be greatly appreciated.
Thanks.

Hey guys, I used VB.NET running on Win2K Advanced Server (SP3). I played around with DataGrid and it went fine. However, there's one point where all the changes I made seem to have no effect on the program when I ran it.
This is what happened:
I created a datagrid containing 3 columns, then I set the datasource to the dataset I read from SQL. It went fine!
Then I tried to play with the property of the datagrid (change the ReadOnly property for the column), and it didn't show any effect when I ran the program. Then, I delete 1 column from the datagrid (so, it's left with 2 columns), however, when I compiled and ran it, the datagrid still showed up with 3 columns!!!
Has anybody experienced this before? Or know the reason behind it?
Thanks in advance for your help!

I haven't used too much of the Windows datagrid, but if IIRC, any changes you make to the grid(like column no, or size) will not be reflected if you use databinding.

I'm trying to parse a CSV string and examples I've found so far do not appear to work with VB.NET
The regular expression I'm trying to work with is
,(?=([^"]*"[^"]*")*(?![^"]*"))
So if I'm coding this in VB.NET I have to replace the double quotes with two double quotes right?....
Therefore, my code is using a simple form with two controls as follows...
Dim re As Regex = New Regex(",(?=([^""]*""[^""]*"")*(?![^""]*""))", RegexOptions.Compiled)
Dim myArray() As String = re.Split(TextBox1.Text)
TextBox2.Clear()
Dim i As Integer
For i = 0 To UBound(myArray)
TextBox2.Text = TextBox2.Text & myArray(i) & vbCrLf
Next
Now if TextBox1 is A,B,C it works as expected
If any of the values have double quotes round them it all goes pear shaped.
Eg. a,"substr1,substr2",3.14,"hello" comes out with 7 elements in my array
a
,3.14,"hello"
"substr1,substr2"
3.14,"hello"
3.14
"hello"
"hello"
this is doing my nut! I've been looking at reference books and still can't get it to work.
Is there someone out there that's going to be my saviour?!?!
cheers
