Wy are you getting this from a label? Why not just get the date/time value from the original variable that set the label's date? No conversion and no parsing will be involved then.

Hey,
I've drawn a drawing in form. For example I have drawn line or circle or ... My problem is I want to save this drawing as image file. Can anybody give me an idea how I can do this?
I appreciate your help.

Draw it onto an Image or Bitmap, then call it's Save method.
If you're already drawing in the Paint event, then just create a member Bitmap, draw onto that, and draw that in your Paint event.

In my code I creat a piechart.
What I have done is stripped down the code to show you what goes where (This code will not work as it needs declarations and values...).
This code will in effect make the picture 'stick' to the form - so that it does not get erased as you move the form.
Panel1 is where the piechart is being drawn.
Width and Height are variables you need to set to the size of the picture you want.
You will also need to include the Panel1.CreateGraphics.DrawImage(b1, 0, 0) command in the Paint event of the objetct you are drawing onto - in fact this is where the magic of this method is...
Give this a go and good luck...

Public b1 As Bitmap
Public g1 As Graphics
b1 = New Bitmap(Width, Height, Panel1.CreateGraphics())
g1 = Graphics.FromImage(b1)
g1.DrawPie(Pen:=myPen, rect:=New Rectangle _
(x:=x + XAdjust, y:=y + yAdjust, Width:=Width, Height:=Height), _
startAngle:=startPos, sweepAngle:=sweep)
Private Sub Panel1_Paint(ByVal sender As System.Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Panel1.Paint
Panel1.CreateGraphics.DrawImage(b1, 0, 0)
End Sub
You always pass failure on the way to success.

hi
i am very amator in vb.net i want build an editor program like notepad whit vb.net but i cannot build menu and their code like open in file submenu and save and ...
please guide me and help.
thanks a lot

Really, your best bet is to buy a book and work through it, or look for some tutorials online. Building a menu is simply a case of dragging it onto your form, and clicking where you want menu items to be, to add them. Making them do something is as simple as double clicking on them in the editor. The code is also fairly simple, just use the FileOpenDialog and FileSaveDialog classes.
But, again, if you're asking this, you're probaby enough of a beginner, that you really need to rely on a book to get you started, as you'll get more structured and consistent help than you cn get from forum replies.

 Iam creating a Text Editor and i have added a toolsrtip control in the form with 7 buttons on it . The size (height) of the toolstrip control is very small. so the buttons on it appear very small. I want them larger(both by length and breadth) and by default the size of the toolstrip control cannot be changed form the Properties window. Please kindly tell me how to change the size.

Thanks for favourable answer "ramskr".
I am trying to generate the grid view table on the control panel through for loop by using the sql query.
I got the code to get the data from the Access data base.
So the thing I need is, code to generate table at run time
Cheers.

how to get the date format in vb?
Jayesh Talsaniya
|
|
|
|
|
Do you need to extract, month, day, year from date?
use -> Date.month , Date.day, Date.year. Also you can convert date to shortdate, shorttime, longdate and longtime as string.
Be simple and Be sample.
|
|
|
|
|
no i dont mean that.
i want to check the format fo the date that is in the textbox contol.
wether it is dd/mm/yyyy or /mm/dd/yyyy or other....

In VB.net there is no direct control to check format. Try with masked text box. You have to write own code on keypress event - first 2 digit should be below 12 (if it is month) and so on.
Be simple and Be sample.

|
|
|
oh is it so?
k thanx for replying.
now i wil code for that.

Unless you limit the input of the user, there's no way to tell what format the date is in, reliably. Think about it. Which number is the month and which is the day in "6/6/07"? With restricting the user to a known format, it's impossible to tell. You could get a good clue if you looked at the culture information though. Chances are, the entered date will follow the standard format for a country. Mostly... Check out the CultureInfo class. You can get the current culture your code is running under and get the DateTimeFormat from there. This would be the culture of the O/S is setup for, NOT necessarily the one the user typed into a TextBox.

In visual studio you can change the settings of grid view control by checking the edit, new check boxes.
First do that and find how the coding got changed in code behind.
I think based on that you can make the changes for your project.
Even I am new to VB.net, but I think it helps you.
