Changing only the registry values will not change the background color.
Have a look at the API: SetSysColors.
It is present in user32.dll
If you want to change the wallpaper and get related information, have a look at SystemParametersInfo which is also present in user32.dll

Thanks, after turning my computer on this morning the background colour has changed, so it seems as though it is working, just not picking up the changes until a reboot..
I thought I should be able to do it through the registry keys as with changing the wallpaper (Which I'm already doing)?
I'll have a look at SetSysColors and see where I get.
Thanks

okay, after looking into it, it seems that I need to use a combination of the api, and registry keys.
I've got it working wonderfully!
Thanks you again for the gentle nudge in the right direction

I want to know how and where to get:
digital certificate file (*.spc, *.pfx)
private key file (*.pvk)
for my .NET application?
and is it free?

You can create test certificates (pfx files) using a tool included in the .NET framework, or alternately inside Visual STudio (Project properties->signing->test certificate).
Test certificates are real certs, however. If you want those, they cost money and you can get that at places like verisign.com

I am trying to display a simple TaskDialog with marquee progress bar but i am getting this error:
Error 1 'whatwhen.frmMain.TaskDialogCallback(Microsoft.Samples.ActiveTaskDialog, Microsoft.Samples.TaskDialogNotificationArgs, object)': not all code paths return a value C:\Users\Jassim\Documents\Visual Studio 2008\Projects\whatwhen\whatwhen\main_form.cs 609 22 whatwhen
HERE IS MY CODE:
string update_string = null;
update_string = "some text here";
updateDialog.RightToLeftLayout = true;
updateDialog.WindowTitle = "title here";
updateDialog.MainInstruction = update_string;
updateDialog.CustomMainIcon = Properties.Resources.whatwhen;
List<TaskDialogButton> updateButtons = new List<TaskDialogButton>();
TaskDialogButton btnCancel = new TaskDialogButton();
btnCancel.ButtonId = 100;
btnCancel.ButtonText = "cancel";
updateButtons.Add(btnCancel);
updateDialog.Buttons = updateButtons.ToArray();
updateDialog.ShowMarqueeProgressBar = true;
updateDialog.Footer = "please wait...";
updateDialog.FooterIcon = TaskDialogIcon.Information;
updateDialog.Callback = new TaskDialogCallback(this.TaskDialogCallback);
int update_result = updateDialog.Show();
private bool TaskDialogCallback(ActiveTaskDialog updateDialog, TaskDialogNotificationArgs args, object callbackData)
{
if (args.Notification == TaskDialogNotification.Created)
{
updateDialog.SetProgressBarMarquee(true, 0);
return false;
}
}

Read the error:
Error 1 'whatwhen.frmMain.TaskDialogCallback(Microsoft.Samples.ActiveTaskDialog, Microsoft.Samples.TaskDialogNotificationArgs, object)': not all code paths return a value
Since your method expects a bool to be returned, at the moment, this only happens if the notification is created. So you need to either add an else or a simple return.
eg:
private bool TaskDialogCallback(ActiveTaskDialog updateDialog, TaskDialogNotificationArgs args, object callbackData)
{
if (args.Notification == TaskDialogNotification.Created)
{
updateDialog.SetProgressBarMarquee(true, 0);
return false;
}
return true;
}

Hi, I can't get the original HTML source in
((HTMLDocument)webBrowser1.Document).documentElement.innerHTML
as the HTML code in viewsource. The code comes without quotes and all of the tag names comes as upper case. Is there any way to get original source in axWebBrowser as in System.Windows.Froms.WebBrowser.DocumentText ?

I think you need to post this in the ASP.NET forum.

The problem is not about ASP.NET, it is encountered in any type of websites (php, asp, aspx etc.) But, I will post it to ASP.NET part too.

I have 2 user controls but I want to randomly add them to a form in a scrollable tile manner.
Each control is referenced by a name, so I can erase a specific control. How do I achieve this can someone give me heads up on how to achieve this..
I cant find anything to get me going.
thanks

Keep a Dictionary<string,control> to hold references to them?
What's giving you trouble?
|
|
|
|
|
can you expand with some more example on your answer as I am having trouble grasping the concept.
I have done nothing like this before.
|
|
|
|
|
I would need more detail from you. Do you know how to add controls dynamically?
|
|
|
|

I have 2 user control which consists of a panel and a textbox and a button is on the panel.
In the form I call the panel(usercontrol) with a button. But I can only make it appear once. I want it to tile across the page. I want to randomly place each user control by a name reference so as I can erase a specific panel.
like so
private void button2_Click(object sender, EventArgs e)
UserControl1 bb = new UserControl1();
this.Controls.Add(bb);
cheers ideasman

1)You most place your controls inside a panel and enable scroll.
2)why destry the control? can´t you built many usercontrols and enable the one you need?

I have used a flowcontrol container in the past to deal with the positioning of the UCs. Placing them manually was a PITA, after designing the UC to match the size of the flowcontrol 1 column width it worked well. I basically wanted a scrollable list of the UCs, one for each application the user has access to.

Are you saying to keep placing this flowcontrol dynamically or do you place it many times on the form
and call the control to it???
|
|
|
|
|
Research the flowcontrol, you will find you place 1 FC and add your UCs to it, the FC manages your positioning (according to your settings) and scrolling.

I am relatively new to C#.
Very generally, how would you implement an authentication system?
You would have a user input form where the user puts username and password.
I suppose a database table would store a permission set?
Suppose you wanted to take the permission and disable some controls on forms.

Is it a web or windows application?
You can´t manage new logins without a database.
Make SQL store procedures for to add,delete logins, to login and to logout.
For security, let only your users execute your written store procedures, (don´t let then type sql for exemple).
