I don't think that there exists a "Scale" Methode for this problem.
But I see that your code above is the solution for your problem. You just have to iterate through the Controls, resize them and set the right position. Perhaps you'll find a good common method for this. Maybe the Anchor property of a Control helps you.
Perhaps this may help too:
Array a=new ArrayList();
this.form.Controls.CopyTo(a,0) //Copies the Controls to an array
Form f=new Form();
foreach(object o in a)
{
Control ctrl=(Control)o; //get the control
ctrl=this.RecalcControl(ctrl) //Common Method to fix size and location
f.Controls.Add(ctrl);
}
void RecalcControl(Control ctrl)
{
ctrl.Size=..
ctrl.Location=..
return ctrl;
}
Your problem will be a good education for C#
Good luck

Ive been working with VC++ for a while and want to begin to learn C#.
Can anyone recommend a good book to learn C#?
Thanx for the help,

I was new to programming when I decided to pick up C# -- Deitel & Deitel 'How to learn C#' was my first book but in reflection its not the best. I once borrowed a MS Press C# book which was way more usefull but I cant remember the title (posibly Inside C#). I guess I was looking for more about programming than just syntax... happy hunting and let us know what you find usefull.

First of all, you need to learn C#, so go with
Inside C# 2nd Edition by Tom Archer (MSPress)
Immediately afterwards, read either one of these:
Applied .NET Framework Programming by Jeffrey Richter (MSPress)
Essential .NET by Don Box(Addison Wesley)
I have also lived some years in Spain, and there people don't accept that you speak bad spanish. I usually compensate by speaking loud and accusing people of being stupid because they don't understand me. It usually works quite well.

Hi,
I was in the same situation and this book was perfect for me as a C++ developer moving to C#:
C# and The .NET Platform, Second Edition
By Andrew Troelsen
Published: Jun 2003 - Apress
ISBN: 1-59059-055-4
1200 pp.
Price: $59.99
You can find it in Amazon, a link to the apress book:
C# and the .NET Platform
I bought later one from Apress about C# and Database programming... it's useful as well.
Good luck

Ok, so I had to write a program in DBase and boy does DBase suck. I just can't even begin to tell you. Anyway, I'm umming and arring about re-writing the whole app in C# and learning C# at the same time.
My app currently uses a bunch of dbase .dbf files (tables) stored on a server and accessed via a network drive from about 8 client machines, all of which are over 1ghz and have 256mb ram or more.
It's task is to manage the accounts and rent payment for a large market with a lot of traders.
It needs to be able to do the following:
1) be quick (dbase is soo slow at updating controls, navigating and scrolling through grids)
2) need to be able to create and embed reports into the program (using a crystal reports viewer control?)
3) needs to be able to print to a dot matrix printer to pre-printed tractor feed paper of a custom size (with was problematic in dbase to say the least..)
4) needs an incremental search (text box bound to a datagrid and a combo box (to select search field) e.g. you select "Name" in the combo box, then type id "Fr" in the text box and the grid then shows the first row in the table who's name starts with "Fr" e.g. "Freddie".
5) needs to be able to handle record locking properly (i'm guessing an sql server or access database will be ok with this..)
6) needs a password control (yes, dbase was lacking one!)
7) need to be able to offer hotkeys on a per form (not per-control) basis. e.g. F2 = New, F3 = Edit, F4 = Save, ESCAPE = Abandon edit.
8) need validated/formatted input (e.g text boxes for phone numbers, currency and dates)
9) reports need to be easy to create (dbase's report designer sucks!)
Those are the main things that I require, I'm just sick of maintaining and developing this horrible DBase code and want to move to something else ASAP, but don't want to spend alot of time writing the application and pulling my hair out over stupid bugs.
I have written lots of C++ code (see www.HydraIRC.com ...) so I don't think picking up the language will be difficult, i'm more concerned with the abve tasks and whether you guys thing C# is suitable, or if not, what about Visual Basic .NET?
Also of concern is the amount of help I can get from other codes should the need arrise, are there lots of C# developers now? or are there more VB.Net developers?
Any urls, commends and advice would be appreciated before I jump in head first.
Thanks!

If you are c++ developer do it with C#,not VB.NET because it has C syntax. The things you want is really good to be written with C# and SQLServer.All these will take half or less code than C++ and it will really save time of developing. ALl the thingsd you want to do in this application is really DUCK SOAP inC#(.Net actually)In this site you can find many beginner articles about these steps in C# and you can ask your questions here too.Its really a big help.You will find C# something great.
But something that I'm not sure is a machine with 256mb ram and 1ghz is enough for run .net application or not.I think it is minimum requirement for it. Hope it helps.

.NET (including C#) really shines for business/data-centric applications, so it should work well. You'll love the data capabilities of .NET.

.NET has good data binding capabilities, and it's fast for this.

You would need a third-party reporting component, such as (as you mentioned) Crystal Reports. There are a couple of really good ones for .NET.

Hmm... this one might be a problem. You might ask about this one on the C# forum. AFAIK .NET doesn't directly do text-only printing. But you can always use the Windows API printing functions if necessary, and it won't be any harder than using them from C++.

That shouldn't be hard.

Yes. BTW, if you're dealing with a large DB, don't use Access - use SQL Server.

.NET has one, and there's also a better one here on CP.

You're welcome to ask questions here on CP if you run into trouble.

C# is definitely suitable. As far as C# vs VB.NET, C# can do everything VB.NET can (except for optional parameters), plus some.

Judging by the amount of traffic in the forums, there are almost as many people doing C# as C++ (although not quite), and more people doing C# than VB. Anyway, there's bound to be plenty of people to answer your questions.

This is off the topic of your question, but I went to your website (www.HydraIRC.com) and had a look at the screen shots. I really like your GUI and was wondering if maybe you had some sample code of how to accomplish the auto-hide, docking, screens etc. Maybe you could even do an article on it and post it here (at CP). It's a really nice interface.
Thanks.

Hi,
I am trying to have an Windows Applcation run over the network. The client machine has the required .NET framework, but when I launch the applciation it is giving me a TypeInitialization exception. It does not even hit the first line. Is there soemthing I need to take into consideration before an application can be run over the network? Thanks,
|

If you are interested in just executing the program from a network share, you will need to set permissions on each of the client computers.
Take a look at Administrative Tools > Microsoft .NET Framework Configuration and do soem MSDN searches for 'code access security'.
This will most probably be what is causing your exception.

I want to paint some colors on the background of my costom windows control and have some button and ... on it.If I overriden the OnPaint and do my painting there,It draw them in front of all things and nothing else is shown.How can I paint background and add controls in front of it?
Thanks

I tried the same and it works.
The background color of the custom control did not hide any controls on it.
How are you doing it? Can you paste your code or some pseudo-code

Simply add this lines to th control:
private void UserControl1_Paint(object sender, System.Windows.Forms.PaintEventArgs e)
{
Rectangle rect = new Rectangle(0,0,this.Size.Width,this.Size.Height);
e.Graphics.FillRectangle(new System.Drawing.Drawing2D.LinearGradientBrush(rect,m_bkcolor1,m_bkcolor2,m_lineargradientmode),rect);
}
But I after I add these two styles it works correctly,but I think it should be works without these two styles too:
this.SetStyle(ControlStyles.UserPaint,true);
this.SetStyle(ControlStyles.AllPaintingInWmPaint,true);

What I would really like to do is tell the parent control to send a button click to a child control. In C++ it would be this
pParent->SendMessage( WM_COMMAND, MAKEWPARAM(ID_Of_CHILD, BN_CLICKED) );
Can you help me with this syntax or point me towards reading material? Below is my best effort. Thanks.
using System.Runtime.InteropServices;
public class Form1 : System.Windows.Forms.Form
{
[DllImport("user32.dll")]
protected static extern int PostMessage(
IntPtr wnd,
uint Msg,
IntPtr wParam,
IntPtr lParam);
.
.
.
private void button1_Click(object sender, System.EventArgs e)
{
*
#define BN_CLICKED 0
#define BN_PAINT 1
#define BN_HILITE 2
#define BN_UNHILITE 3
#define BN_DISABLE 4
#define BN_DOUBLECLICKED 5
*/
const uint WM_COMMAND = 0x0111;
const uint BN_CLICKED = 0x0000;
PostMessage((IntPtr)BusinessRules.Handle, WM_COMMAND, (IntPtr)BN_CLICKED, (IntPtr)IntPtr.Zero);
}
private void BusinessRules_Click(object sender, System.EventArgs e)
{
System.Windows.Forms.MessageBox.Show("I was clicked");
}
|
|
|
|
|
Unless I'm missing something, just call PerformClick():
private void button1_Click(object sender, System.EventArgs e) {
BusinessRules.PerformClick();
}

Thank you.
The PerformClick is akin to SendMessage(). It takes place immediately.
I was hoping for a PostMessage()type behavior.
Any ideas?
thanks

I would like to set focus on the 1st control that does not have data.
For most controls I can ask in the text field is empty. But for checkboxes and radio buttons, I must ask for the special case of 'GetChecked'. If it was only these two types of controls the code below would be OK. But controls derived from Checkbox and Radio button would also need special case code.
How can I ask if a control is a checkbox or derived from a check box?
public void SetFocusOnFirstEmptyControl()
{
int iCount=0;
System.Windows.Forms.Control Traverse = this;
//System.Reflection
while(Traverse != null)
{
Debug.WriteLine(++iCount + " " + Traverse.Text );
if(Traverse.GetType() == typeof(System.Windows.Forms.CheckBox))
{//do special case handling for check box
System.Windows.Forms.CheckBox pCheck = Traverse;
if(pCheck.Checked()== false)
{
Traverse.Focus();
break;
}
}
if(Traverse.Text.Length == 0)
{//test controls like textbox and dropdown
Traverse.Focus();
break;
}
Traverse = GetNextControl(Traverse, true);
}//while
