Hi
Is it possible using GDI+/.Net Framework to draw text along a path. For example, I want to draw a bezier curve that looks like an "S" shape, and I want the text to render along the shape.

Thanks

I'm sure it is possible. You'll probably have to create a custom text control in order to do so.

changing desktop colour doesn't work

Hi,
I'm trying to change the background colour of my desktop. Here's the code I'm using:

RegistryKey rkWallColor = Registry.CurrentUser.OpenSubKey("Control Panel\\Colors", true);
rkWallColor.SetValue("Background", "0 0 64");
rkWallColor.Close();

I'm sure that I'm doing it right, but the desktop colour wont change. I've checked the registry key and it has been changed. Am I accessing the wrong key?
I'm using windows xp.

Can anyone see what I'm doing wrong?
Thanks

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

regards

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 Smile | :)

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

TaskDialog: Marquee ProgressBar Problem

Jassim Rahma3-Aug-08 10:35

3-Aug-08 10:35

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;
}

Gareth.

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.

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?

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);
