Re: Returning Items and SubItems from ListView

Get the value of ListView.Item[index] and its subitems through a loop. (foreach), it also contain a property name SubItems which you can get sub items from it.

Hey

I got a Class that contains a ArrayList, this Array list is containing objects from another class(also Serilized). How do i Serilize class that contains tha Array list so i can send it over the socket and on the client side use the ArrayLists Objects?

I think(not an expert):
You need to take every item in your ArrayList, find out what object type it is. Serielize every items value in those objects that you need to recreate those objects. Send the file to the client. The client opens the file, creats objects and adds them to an ArrayList.

I don't think there are any standard methods for serializing an ArrayList

Hope it helps

The ArrayList class is already attributed with the SerializationAttribute, meaning that is is serializable. When you use the classes from the System.Runtime.Serialization namespace, any such attributed class (and this attribute is not inherited by derivative classes, so to speak) has its private and public fields (not properties) serialized if they are attributed with the SerializationAttribute.

So, all you need to do is attribute your class (if you haven't done so already) and serialize it. The ArrayList will be serialized, too.

Now, in the case of XML serialization (using the System.Xml.Serialization namespace), only public properties and fields are serialized. This can be controlled using the attributes from this namespace. This type of serialization is not as good as the runtime serialization, though, because the latter takes much more into account and can also serialize into about any form you like (SOAP and binary formatters are provided with the .NET Framework base class library).

For more information on serialization in .NET, see Serializing Objects[^] in the .NET Framework SDK for more information and lots of examples for both types of serialization.

For seialization of an ArrayList you would have something defined like this:

[Serializable]
public class myList:ArrayList
{
     incorporate strong-typed exposures
}

[Serializable]
public class myDataType
{
   private data and public accessors
}

Now you can easily Marshal this ArrayList across an application boundary.
If your applications closely follow the MS Design Guidelines, you would have to change the ArrayList to a Collection, since the MSDG states that Arrays should not be Serialized.

How to display frame or panel on top of DirectDraw video window in Fullscreen mode?

mdundek3-Feb-04 22:34

I came accross the DirectShow Media Player article (http://www.codeproject.com/cs/media/DirectShowMediaPlayer.asp) and added a fullscreen mode to that sample application. My problem is that I would like to be able to display a panel on top of that Video window when I move the mouse cursor (I cant even display the mouse cursor when moving mouse). But it seems that the Video window covers everything. Does anybody knows how to solve this (must be possible, since I can make a Context menu display on top).

Thx in advance...

Deployment project: adding uninstall icon

4-Feb-04 4:03

The video window is designed to cover anything. This is true of most video players, mostly to facilitate DRM and DRM-like technologies so that you can't take screenshots of unlicensed material and other stuff like that. If there is a way, it'll definitely be a hack that would void your license and would be a difficult one at that. Especially in the case of Windows Media Player, it was designed by Microsoft so they would know all the (possibly) undocumented APIs to use to keep windows from overlapping in the same process or when in full screen.

Hi everyone,

Is it possible to add an "Uninstall" shortcut to the user's programs menu in addition to the shortcut to the project output when creating a setup deployment project in VS.NET 2003? And if so how? I can't seem to find a way to do this, any clues are highly appreciated!

Thanks,
rado

Windows Installer automaticlly contain uninstallshield too. There is no need to do that. If the program installed and you run installer again it shoes the Uninstll option..

Thank you for your response. I know that the installer adds an uninstall item automatically to the Add/Remove Programs in the Control Panel, and the Setup deployment project even allows you to change the icon that is used there.

What I am trying to do is include a shortcut to uninstall the application into the application's folder in the user's programs menu. I can add a shortcut to the main project output there (so the user can launch the application from the Start -> Programs -> ProductName menu). I would also like to have the "Uninstall ProductName" shortcut in the Start -> Programs -> ProductName menu, as I find this more convenient for users that want to try the application.

Thanks again,
rado

Windows Installer is a completely separate product from Microsoft. It includes a runtime (msiexec.exe) and the install packages are actually relational databases. Trust me, I've been beta-testing this since before 1.0 and consult for several companies regarding their installers.

InstallShield is a company that makes an development environment for Windows Installer, just like Wise Solutions does.

for the answer to this question, see my direct response to the initial post.

Since you're using the Windows Installer project in VS.NET, you can add an icon by first adding the icon to your project. The best way, however, is to use the icon embedded in your application (if you have an application as part of the installer, or even a library will do - anything with icons embedded (and that means into the executable, not as an embedded resource in the assembly)).

First (as I mentioned) add the icon or application to your installer project. Find the folder in which this will be located using the File System view, right-click and select either File or Project Output (project output is especially handy for projects in your solution, that way the latest build of that project is a dependency of the setup and the latest version is always used). Then, select the project itself in the solution explorer. At the top of the Property Grid, you'll see an AddRemoveProgramsIcon. Select the drop-down and click (Browse...). It will give you a window showing you all the possible files that can be icon sources. Select the appropriate one from the directory in which you added the icon or executable before. Click OK.

Thanks for your response, but this only changes the icon that is displayed in the "Add/Remove Programs" (unless I am doing something wrong), I was looking for a way to add a "Uninstall" shortcut to the user's "Start / Programs" menu.

But thanks anyway for a detailed response! Smile | :)

Re: Problem with arrays...

5-Feb-04 4:14

Sorry for the misunderstanding.

Windows Installer recommends that you DO NOT add an Uninstall shortcut to the start menu. In fact, IIRC, this violates Windows Installer guidelines and you cannot certify your application for Windows.

If this is not a big deal, you could do so by making a shortcut to msiexec.exe and use "/x [ProductCode]" as the command-line parameter.

Unfortunately, the crappy Windows Installer project in VS.NET won't let you do this (as well as MANY other things, which is why I never use it and either use Wise for Windows Installer or from scratch with Orca). You need to download the Windows Installer SDK, part of the Platform SDK, which includes an install for a handy utility called Orca. This opens the MSI package as it is - a relational database. You can find more information about the Platfrom SDK from http://msdn.microsoft.com/platformsdk[^].

Once you do this, you need to enter the following information into the Shortcut table:

(Column: Description)
Shortcut: Unique key - type anything
Directory_: Key to a directory in the Directory table for your program group
Name: Name of the shortcut (i.e., title)
Component_: Key to a component in the Component table for which this shortcut is associated
Target: [SystemFolder]msiexec.exe
Arguments: /x [ProductCode]
Description: Description of the shortcut
Hotkey: Leave empty
Icon_: Key to an icon to use in the Icon table
IconIndex: 0-based index for icon if Icon_ points to an executable
ShowCmd: 1 for normal, 3 for maximized, 7 minimized/not active

If you like, I could also probably send you Orca since the EULA seems to allow it so long as I send you the entire installation (which isn't bit). If you would rather me do that, send me a direct email (you can get my email from the message sent to you if you configured your settings for notification of replies).

Problem with arrays...

Andres Coder3-Feb-04 21:46

Andres Coder

3-Feb-04 21:46

I was learning array and came to a problem I ...

I have a struct containing some info:

public struct SomeInfo
{
   public string Value1;
   public int Value2;    
   public SomeClass Type1;
}

And an array of SomeInfo: public SomeInfo[] SomeArray;

So by now I should have an array that every item has 3 properties (Value1, Value2, Type1) and I can access them by doing like this: SomeArray[1].Value1 = ... Right ?

The only problem here is that the size of SomeArray array if fixed (I cannot add any more items if the array is full). I also cannot use ArrayList, because that way I cannot access the array item's properties (Value1, Value2, Type1), right ? So what to do ?

Think of as of the classical addressbook example - You have a struct named Person with 3 fields - Name, Age, and a class for some reason. Also a array that contains the list of Persons.
