Hello,
I am looking for a way to programatically edit the web.config file for the section below. Most importantly I will need to set the website login password to a certain value stored in the database. The password keeps changing in database whereas username remains the same. Can you please suggest a way this can be done in C# 2.0?
<authentication mode="Forms">
<forms loginurl="Login.aspx" timeout="60" protection="All">
<credentials passwordformat="Clear">
<user name="testuser" password="test123" />
</credentials>
</forms>
</authentication>
Thanks!

I reckon the folks in the ASP.NET forum may know the answer. I believe the answer is no, tho.

I created a proxy application that sits locally, and a web service that communicates with my local proxy. I pass in a website and it passes back the raw data, pretty basic.
What I can't figure out how to do is get the images back as well for the page.
Take google for example, the page comes back fine, but the banner doesn't.
Should I parse the incoming HTML for the image tag then do a seperate request for that image? If so, how would I get it to the currently viewed page?
Any Idea's?
Hope this makes sense.

Hi,
I have got a MDI app where one of the childforms must be able to see the status of a RadioButton on a docked panel on the MDI from. I want too use the mousedown event on a child frmShow to draw lines on the form if the radPoly was clicked on the pnlTools on the parent MDI form. Please help with a simple code example.
Thanks
Ian

Ian,
It isn't a real simple example, but you could take a look at my Extensions to DrawTools[^] article which has the type of ability (and more) you are looking for.
In that application, the MDI parent form sets properties on the DrawArea object to communicate settings from parent to child.

Ian,
The DrawTools project uses a MDI parent form - I had forgotten it doesn't use any child forms.
Try this out for a solution to your problem:
In your child form expose some public or internal properties that are set when a toolbar button in the parent form is clicked. For example:
*** child form ***
public bool isPoly;
*** parent form ***
In the toolbarButton_Click(...) event:
if (ActiveMdiChild == null) return;
var child = ActiveMdiChild as childformclass;
child.isPoly = toolbarButton.Checked;
This way the child form(s) can see when a button on the toolbar in the parent is checked or not and react accordingly.
Additionally in the parent form you will want to react when the child form changes and set the state of buttons according to the active child form:
*** parent form ***
In MdiChildActivate event:
if (ActiveMdiChild == null) return;
var child = ActiveMdiChild as childformclass;
toolbarButton.Checked = child.isPoly;
HTH

Thanks Mark,
This was really helpfull !! I used to work in VB6 Pro and thought about moving over to C#.Net instead of VB.Net. In order to learn the new C#.Net environment it seems you have to buy a lot of books (four up to date) and do the Microsoft certified courses and still all of it only shows you bits and pieces and end up becoming very expensive.
So what I am trying to say is that the code you supplied helps me a lot in grasping whats happening.
So thanks again for your patience.
Ian

Ian,
You are very welcome - glad I was able to help.
I came to C# after making a living programming in Visual FoxPro for close to 10 years. I picked up some Java experience along the way as well. When I started learning .NET and C# I too bought several books - the best one for me was Windows Forms 2.0 Programming[^].
Hang in there and don't be afraid to ask questions on CodeProject - everyone here is very helpful.
Sincerely,
-Mark

Why? Best Practice would be for views to get their data from the Model rather than another View. See Model-View-Controller[^]

No,
I had a look at the Wiki and it does not tell me much in a practical way of achieving this.
But thanks in any case

Ok, I guess unless you can copy/paste some code you can't do it. Good luck.

Hello friends I have a function name " private void fnSave()". I want to call this function when ever I press " Ctrl+S " button. Just like in MS Word.Can any one help me plz?

You can use KeyDown, KeyPress and KeyUp events to detect pressed keys.

Hi Saiyed,
In MS Word the Ctrl+S key combination runs the code assigned to the File..Save menu item. It's called a shortcut key and if you are implementing menus in your application you can do this too. Shortcut keys can be assigned to menu items in the Visual Studio designer.
Alan.

Thank u Alan. But is it not possible to implement that without using Shortcut key in menu item?
If there is then how? All I want is just to call a function like private void fnSaveData() whenever some one press (Ctrl+S) together.
|
|
|
|

Hi Saiyed,
Try this in your app.
Set the KeyPreview property of the main form to true and also set a KeyDown event handler for the main form.
With these two elements in place, the main form key handler will see all keys destined for any child control on the form so it will not matter which control has focus when the user presses Ctrl + S.
You can then test specifically for Ctrl + S as shown in the code fragment.
private void MainForm_KeyDown(object sender, KeyEventArgs e) {
if (e.KeyData == (Keys.Control | Keys.S)) {
MessageBox.Show("Key trapped" + Environment.NewLine +
e.KeyData.ToString());
e.SuppressKeyPress = true;
}
}
Just insert your save method in place of the message box code.
Alan.

How would i go about changing values in pixels in an area? Note, all pixels will have the same value.
I was thinking of using unsafe code to visit every single pixel in that area, but that may be too slow if i do this multiple time.
|
|
|
|

YOU CAN USE SetPixel()
Bitmap bitmap = new Bitmap(@"C://1.bmp");
Color newColor = Color.FromArgb(0, 0,100);
bitmap.SetPixel(i, j, newColor);
