I have the need to group a set of text boxes and labels for ease of use. I want to put a simple box around these items and I am not sure if a GroupBox is overkill for it.
Any recommendations or is it fine to use a GroupBox for nothing but aesthetics?
Thanks,
Dan

A GroupBox is a pretty lightweight control. It'll work for what you want it to do. Just don't expect a lot of customization options with it.

hi,
i create simple png file which draw user specified string. i accept input from user through Text box(here name is txtString).However following code create Png file but size is more(above 1 KB) for simple string which contains few character(here string contains "aaa").
Dim g As Drawing.Graphics = Nothing<br />
Dim bm_width As Integer = 170<br />
Dim bm_height As Integer = 200<br />
<br />
Dim newBitmap As Bitmap = New Bitmap(bm_width, bm_height, Imaging.PixelFormat.Format24bppRgb)<br />
g = Drawing.Graphics.FromImage(newBitmap)<br />
g.PageUnit = GraphicsUnit.Pixel<br />
g.DrawImage(newBitmap, 0, 0, bm_width, bm_height)<br />
<br />
g.FillRectangle(Brushes.White, 0, 0, bm_width, bm_height)<br />
Dim b As Font<br />
Dim a As New FontDialog<br />
If a.ShowDialog = Windows.Forms.DialogResult.OK Then<br />
b = a.Font<br />
End If<br />
<br />
Dim str As String<br />
str = txtString.Text.Trim <br />
g.DrawString(str, b, Brushes.Black, 0, Ypos)<br />
newBitmap.Save("c:\Drawing\" & txtString.Text.Trim & ".png", Imaging.ImageFormat.Png)
how can we reduce size of PNG file.
any help will be appreciated

PNG is already a compressed format so you're not going to get a smaller size file. Who cares what the text is. On a pixel-by-pixel basis, the more complex the image is, the less "compressible" the image is going to be and the bigger the resulting file.

I agree. I've noticed his code has a fixed bitmap size and have wondered if he should set the bitmap depending on the text size (unless he's forced with a 170x200 image)...

Hi all,
A problem takes me back once again to the code project.
Right now I'm working on a small project in which I would like to generate my buttons, textfields etc dynamicly (I have an xml file and when it encouters < control type= button name = btn1/> it creates a button called btn1 and its added to the page (its possible to set the size etc.)
The reason why I'm doing this is that from time to time you just want to add a simple button but don't feel like recompiling the whole project or a client wants an extra button/image and would like to add it himself.... (with some sort of wizard typed thing)
this is all working. buttons and controls are created without a problem. I can retrieve info from my textboxes etc no problem. But well lets say I want to create a button but it needs a new "function" while clicking on it so I would need to add a handler to the button but I don't know what the code is going to be so I added in my xml file: <control type= button name = btn1 handler= btn1_handler/>
This function is then coded in an external file (simple notepad for exemple)
now where I dont really know how to do it is associate this function btn1_handler with my btn1 so that it handles an onclick event... the whole thing without recompiling but using for example vbscript or ICodeCompiler.....
Would this be possible to do? or? because well I dont know what will be in the function nor which button it corresponds to except in my xml file....
any help would be greatly appreciated 
Cheers

It's possible. I don't exactly know how, but it is.
I'm figuring that you would have to load the button handler text into a CodeDom and compiler it into an in-memory assembly. This assembly would then have to be loaded into the AppDomain, kind of like plugin functionality. You'd then have to wire up the event handler yourself after the code is loaded.
Don't ask for example on this one for I don't have any. This is all just speculation. I've given you enough keywords to Google on to get the smaller parts of the problem solved though. After that, it's a matter of stringing those smaller solutions together to get this to work.

Okay, thanks alot, I think I will find a way with the different info you have given me and its good to know it's possible to avoid searching the internet for days and finally realising it isn't possible
Thanks again, and well if I find it I'll be sure to share it in here
Cheers

Hi,
If I have a dataset with a couple tables, is it possible to take one of these tables and copy it over to another dataset? I just want one table in my dataset.
Regards
ma se

use clone - copy the structure
you can either copy the rows manually or use writexml/readxml to transfer the rows.

Hi,
My XML format looks like this:
<?xml version="1.0" encoding="utf-8"?>
<Products>
<Product>
<ID>5555</ID>
<ProductName>My Product</ProductName>
<Price>50</Price>
</Product>
</Products>
I need to know how to get this into a dataset, then I will have more control of the data. I know there is a function that saves the XML into a datast, but how does it know that I want the fields in the <Product></Product> hierarchy?
Or how should this be done?? I just want the <ID>, <ProductName> and <Price> to be the column names, and the values in tags the values of the fields in the row.
Regards
Brendan

It looks like you have the right structure to just to a ds.ReadXml("c:\temp\filename.xml")
So <Products> would be your dataset
You table would be <Product>
so multiple rows would look like:
<Products>
<Product>
<ID>5555</ID>
<ProductName>My Product</ProductName>
<Price>50</Price>
</Product>
<Product>
<ID>6666</ID>
<ProductName>My Product2</ProductName>
<Price>60</Price>
</Product>
</Products>
So I don't think you will have to do much to get this working.

i want to override a button property in winform not an event

Would you not have to inherit the button control into your own class and expand on it from there?

You'd have to create your own Button class and override the property. To make the Text property disappear and have the Text on the button be forced to something:
Imports System.ComponentModel
Public Class MyButton
Inherits System.Windows.Forms.Button
<Browsable(False)> _
Public Overrides Property Text() As String
Get
Return "This is my custom button!"
End Get
Set(ByVal value As String)
' Just don't do anything with this
End Set
End Property
End Class
