What do you mean, "to the internet"? To a web application or web service on the internet?

How to draw full DataGrid row???

Hi All,

I want to add grouping function to DataGrid(vs 2003) control, like outlook. but I need a row (cover columns) to show the group title. By the way, my datagrid is bound to Arraylist!

Does anyone have ideas about how to draw a full row in DataGrid control (not DataGridView)? This row will cover all the visible columns. and there should no grid line, the content need to cover all the columns.

Thanks a lot for any suggestion!!

How to tied enum to a class

Lets say I have

enum OutputFormat {
HEX,
BINARY
DECIMAL
}

class Foo{
...
...

public void print(OutputFormat x){
....
....
}

foo y = ....;
y.print(OutputFormat.HEX);

But I'd like to ties the enum to the class so that the call would look like

y.print(Foo.OutputFormat.HEX); instead of the y.print(OutputFormat.HEX);

Any ideas>

Thanks

class Foo{
public enum OutputFormat {
HEX,
BINARY
DECIMAL
}
...

}

You can also use private to make the enum only useful within the class.

I'm a retard. I could swear that I retried that and got a compiling error!

It works now.

Thank you very much, I can stop banging my head on the desk.

Security Question

Hello,

I have an application that saves files to the server. Users don't have the righ to edit any of the documents in the file system. One way to do it, is to use impersonation to modify the files, however in Win 2000 for impersonation to work one has to modify the security policy, which poses the security risk. So my question is, how can I allow the users to modify files on the file system only through the application?

Thank you.

form return problem!

Hi folks,

Here's my problem: (and the source of my frustrations)

I'm writing an app to control a service.. Now, the settings of this service are kept in a serialized file, which is the serialized form of my configuration - object...

The user should be able to specify certain settings by pressing a button,
so what I do is passing an instance of the configuration class to the SettingsForm.

e.g. frmSettings formsettings = new frmSettings(myConfiguration);

now for the big question: How can that frmSettings RETURN the modified myConfiguration to the parentform without having to go to the trouble of serializing the stuff, writing it to the disk and deserializing it again in the parent form...

Thank you very much for your response!

I don't see the solution here on first sight.. I'm really trying to return an instance of an object (not a value) when the user chooses to commit the changes...

Yes, and a value is.... an instance of an object.

You need to put all of your painting code in your form/controls Paint event.

Crap! Hopefully next year!

Next time you're in Toronto, let me know. I'll see if I can convince the wife we need a quick get-a-way to Niagra Falls or something! Laugh | :laugh:

Besides, it'd be interesting to see where all this CP stuff, my wife calls it "porn", in stored.

In C++, you should have done the same thing you should do in C# - draw your shapes in the Paint event handler of the form, so it gets told to redraw itself when the form is obscured in any way and then shown again.

Loading in a background on my form problem

Appologise for my earlier post, as mention before i am a new programmer and my posting etiquette needs improving.... again i appologies.

Can anyone help me with a problem of loading in a backgroun onto my form. I know you can load a picture box from the tool box and set this as your background but this is not what i'm try to achieve.

The problem appears to be in this line of my code (code added at bottom)

Bitmap background = new Bitmap(GetType(), "background.jpg");

I get the following error when press F5 to run my app.....

Resource 'background.jpg' cannot be found in class 'Game.Form1'

I have added this image as a resource (solution explorer > title properties > resources > add image.

This is my code in full:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Data;

namespace Game
{
public partial class Form1 : Form
{
// insert private bitmap background
// and movement int x/y move etc.....

private Bitmap background = new Bitmap(640, 320);
//private Bitmap car;
//private Bitmap player;

public Form1()
{
InitializeComponent();

//player = new Bitmap(GetType(), "player.jpg");
//car = new Bitmap(GetType(), "car.jpg");
Bitmap background = new Bitmap(GetType(), "background.jpg");

this.SetStyle(ControlStyles.DoubleBuffer, true);
this.SetStyle(ControlStyles.AllPaintingInWmPaint, true);
this.SetStyle(ControlStyles.UserPaint, true);

Graphics g = Graphics.FromImage(background);

for (int x = 0; x < 640; x += 90)
for (int y = 0; y <= 290; y += 90)
{
g.DrawImage(background, new Rectangle(x, y, 90, 90)); // GraphicsUnit.Pixel);
}
}

}
}

Regards,

Thank you for taking the time to read this Smile | :)

If you've added the image as a resource, and you're using Visual Studio 2005, you can access it like this:

Bitmap playerBitmap = Properties.Resources.player;

Strange problem with WebBrowser control "double loading" a page, eh?

ThisIsMyUserName214-Mar-07 6:57

14-Mar-07 6:57

This is a very strange problem I came across and it's a show stopper for my current app. It happens all the time on the site I'm trying to interact with and it occasionally happens on google.com (or any site I'd imagine).

I'm trying to run a series of events depending on what URL is currently being navigated.

In my WebBrowser's DocumentCompleted event I have a switch which runs a different set of methods based on the URL.

After a document is complete, it'll run the switch fine but it runs what's inside of the case I'm trying to detect more than once. It's easy to see by placing a messagebox output. It'll come up 2 times instead of once.

I tried other ways of determining which page I'm currently on. Like using the DocumentTitleChanged event instead of DocumentCompleted, but I think DocumentCompleted is safer because it won't do anything until the document is loaded. Either way, the problem exists with DocumentTitleChanged too.

Any ideas? Btw I excluded the site where it occurs all the time because it requires a login and unfortunately I can't share it publicly. If you want to do a test, just throw together an app really quick and drop a messagebox into the DocumentChanged event, then have a textbox where you can enter different addresses -- it's bound to come up.

They hide that information in the DOCUMENTATION[^]

Remarks

The value of the URL parameter might not match the URL that was originally given to the WebBrowser Control. One possible reason for this is that the URL might be converted to a qualified form. For example, if an application specified a URL of www.microsoft.com in a call to the Navigate or Navigate2 method, then the URL passed into DocumentComplete is http://www.microsoft.com/. In addition, if the server has redirected the browser to a different URL, the redirected URL is passed into the URL parameter.

The WebBrowser Control fires the DocumentComplete event when the document has completely loaded and the READYSTATE property has changed to READYSTATE_COMPLETE. Here are some important points regarding the firing of this event.

* In pages with no frames, this event fires once after loading is complete.
* In pages where multiple frames are loaded, this event fires for each frame where the DownloadBegin event has fired.
* This event's pDisp parameter is the same as the IDispatch interface pointer of the frame in which this event fires.
* In the loading process, the highest level frame (which is not necessarily the top-level frame) fires the final DocumentComplete event. At this time, the pDisp parameter will be the same as the IDispatch interface pointer of the highest level frame.
