Thanks for the suggestion though Smile | :)

Scheduled Tasks

Hi,

Does anyone know if it is possible to call the Scheduled Task interface from C#. Its located here Start -> All Programs -> System Tools -> Scheduled Tasks. Once you Add a Scheduled Task and you get the properties of it -- this is the interface I would like to call. Is there a class in C# that will handle this. I have seen Symantec using this in their Norton AntiVirus program. Any help would be greatly appreciated since I need to do this in my program. Thanks

Yes very similar to this, but is there a way to called the actual design interface within windows without having to shell out into DOS. It would be nice to call the interface design within windows. There has to be someway to call this but I can not seem to figure it out. This is what I am trying to call: If you got to Start --> All Programs --> Accessories --> System Tools --> Scheduled Tasks. Click Add Scheduled Task and pick the options you want for your particular job. Once your job is add, click on it and get its properties. A window pops open showing you the job you just scheduled. This is the window, I am trying to call. Is it possible to call this either from a class library or a dll in windows? If this isn't possible, is there a way to call the actual wizard (Add Schedule Task)built into windows?

If anyone else might be able to provide me with some help, I would be greatful. Thank You.

Delegate argument question/suggestions...

I'm in the middle of writing a Source Safe automation tool and I have a Traversal method which takes a delegate. While I've used delegates quite a bit in the past I've never really run into the issue where I've needed to pass things along to my delegate that couldn't be found derived during the traversal. IE Checkout delegate needs a checkout destination. I have ideas, but would like some more if anyone has some.

I don't understand what you're asking. What does the delegate need to do?

Actually I solved my problem nicely or at least nicer than my quite poor path was taking me earlier. Here is what I was in need of solving, what I was thinking of doing, and what I did:

I had a traversal method which accepted a delegate as a param. This method is, of course, called during the traversal on each VSSItem retrieved from the database.

My original goals was to pass the extra arguments need by each different delegate implementation through the traversal method and then pass them into the delegate call each time. While this may be fine and dandy when you know the signature of the method I didn't want to do that. I thought of using a param list but that isn't really nice either, avoid indexers at all cost type of thing. So my final thought was really what I need is a sub-class, or external, whatever ties your shoes, that would take care of that type of process. IE a GetHistory, GetFile, or Checkout class that really only concerned itself with one file at a time, but knew what it needed and only that (selfish I know). That class exposed a method that was used as the delegate. Its quite nice and quite clean. Any thoughts...

That sounds reasonable. It's similar to the way events typically work; they always pass the sender as an object, and then the values as a class derived from EventArgs.

Converting images

i heared that there is a function in c# that convert images from a format to another ( like from bmb to jpg)
do anyone know it?

Re: Converting images

Luis Alonso Ramos29-Jul-02 6:37

The idea is to use the Image class to load an image in one format (FromFile static method) and save it with another format (Save method). For example:

Image img = Image.FromFile("image.jpg");
img.Save("image.bmp");  // Use file ext to determine type

That's it!

Equivilent of session in windows

Anonymous29-Jul-02 3:21

Is there a way of applying something similar to the web's "session" to a windows application (many forms, MDI parent window)? I want users to be logged out after 20 minutes.
Thanks

Hi,

You can use a Timer. Activate it on application start, set it for 20 minutes, and reset it everytime the user does the required function, like clicking a specific button or whatever... I have used it for a BlackJack game where the user has 1 minute to bet, if not he get removed from the game and the game continues. Just a tip, print starting and stopping times in the console so u can see whats happening Smile | :)

.

Hope this helps

I was thinking of this, but the application is complex and contains multiple windows. So i'd need to map every navigation back to the original window and its timer, which is not really practical.

XMLTextWriter ???

I'm under the impression I can use the XMLTextWriter to output my XML nicely formatted, but my attempts so far have failed. Does anyone have any ideas ?

Thanks.

I may be going over the obvious here but:

xtwArticles = new XmlTextWriter ("test.xml", 0);
xtwArticles->Formatting = Formatting::Indented;

That is the C++ version that I am using and the XML comes out nicely formatted. For the C# version just replace the 0 with System.Text.Encoding.UTF8

Comes out of where ? I have a complete XML file which is not formatted, coming out of an XmlDocument. I tried passing it into an XmlTextWriter as a string and pulling out the result, but it was just a blob of unformatted XML, just the way it started.

I want to take
<xml><node><subnode>sdjkfsl<node><node2>sdfsf
for example, which I have as a string, and pass it into something that formats it. I've actually written my own function which does this, but I'd prefer to use the one provided if I can make it work.

*sigh* I am not devout anything. Yes I have up until a short time ago mainly been using VB, though that is really VBScript and that was a limitation of ASP and so was forced.

However VB has always been up to my needs and it is good at what it does. Right tool for the right job.

As for venturing into C++: I am entering the Visual C++.NET competition Big Grin | :-D

I thought it would be a fun thing to learn and also as a way to prove that a VB coder can do C++.

That "C++ version that I am using" bit is because my MC++ class writes and reads some XML.

I like knowing a little bit about everything, makes me dangerous (you know, the saying "A little knowledge is a dangerous thing" Big Grin | :-D

Hi,

If you look at an article about XmlSerializer submitted end last week, you should get an better idea too. Smile | :)

Here some code i have used:

System.Xml.XmlTextWriter xmlwriter = new XmlTextWriter(filename, System.Text.Encoding.ASCII);
xmlwriter.Formatting = Formatting.Indented;
xmlwriter.WriteStartDocument();

xmlwriter.WriteDocType("Options", null , null, null);

xmlwriter.WriteComment("MYrc Option File. Edit at own risk!");
xmlwriter.WriteStartElement("Options"); //root element

PropertyInfo[] props = this.GetType().GetProperties();

foreach (PropertyInfo prop in props)
{
    xmlwriter.WriteStartElement(prop.Name);
    object da = prop.GetValue(this, null);
    xmlwriter.WriteAttributeString("Type", prop.PropertyType.ToString());
    if (da != null) xmlwriter.WriteAttributeString("Value",da.ToString());
    else xmlwriter.WriteAttributeString("value", "null");

    xmlwriter.WriteEndElement();
}
xmlwriter.WriteEndElement();
xmlwriter.WriteEndDocument();
xmlwriter.Flush();
xmlwriter.Close();

This is for an OptionGrid class in trying to get going, but I have had no success with non primitive types Frown | :(

, but it works well with primatives Smile | :)

Hope this helps.

Thanks - I had seen that the writer could be used to write XM a node at a time, but I already have the XML as a string, and I want to pass it in one go. A method is provided to do this, but I tried it and it did not format the XML for me, it just passed it back. I set the Formatting to be Formatting.Indented before I passed the string in.

Problem at creating a vs.net wizard

Feng Qin29-Jul-02 1:47

Feng Qin

29-Jul-02 1:47

Hi, all
I try to create a wizard for vs.net when new project or file, when I test my wizard, vs.net always pops up a dialog "Could not run the xxx wizard".

firt part is my dll source:

using System;<br />
using System.Windows.Forms;<br />
using EnvDTE;<br />
<br />
namespace MyVSWizard<br />
{<br />
	/// <summary><br />
	/// Summary description for Wizard.<br />
	/// </summary><br />
	public class Wizard : Object, IDTWizard<br />
	{<br />
		public Wizard()<br />
		{<br />
			//<br />
			// TODO: Add constructor logic here<br />
			//<br />
		}<br />
		public void Execute(<br />
			object Application,<br />
			int hwndOwner,<br />
			ref object[] ContextParams,<br />
			ref object[] CustomParams,<br />
			ref wizardResult retval<br />
			)<br />
		{<br />
			MessageBox.Show("Hello world");<br />
		}<br />
	}<br />
}

then I use "regasm /codebase" to register the dll as a com and get the clsid ={34470340-B2D6-39A4-AFDA-A53A13D04DF7}.

then my .vsz file

VSWizard 7.0<br />
Wizard={34470340-B2D6-39A4-AFDA-A53A13D04DF7}

then my clause in .vsdir file

MyWizard.vsz|{34470340-B2D6-39A4-AFDA-A53A13D04DF7}|0|270|My First Wizard|{34470340-B2D6-39A4-AFDA-A53A13D04DF7}|0|0|MyClass.cs

Inheriting a Windows Form as a User Control

Anyone have any idea if it is possible to take an existing Windows Form (filled with working controls) and have it inheret to a User Control?

Otherwise I am going to have to copy over everything from the Windows Form to a new User Control, which is a chore Smile | :)

Hi Paul

How about just changing the inheritance part from Form to UserControl and remove the Main method?

There mite be one or 2 form specific Properties that needs to be removed if the compiler complain, also compile as class library, and then just add the dll to the toolbox, and walla you have a UserControl.

Hope this helps Smile | :)
