hi all,
I am using a listview to display thumbnail of images with some text. i have used largeicon view to display them.
i have created the thumbnail images and its displayed. as in explorer, i need to have the thumbnail image displayed as a folder. (like a border to the thumbnail and text).
How can i do it? i saw a article here in Codeproject but the code is in VC++.and i am not aware of this.
Is there any way to accomplish the same?
Thanks in advance.

Yes there is. First of all you need to set OwnerDraw property of ListView class to true. By doing this you are responsible for providing code for drawing the control. After that handle the ItemDraw event of the listview class to make necessary drawings.

hi,
Thanks for your help. i have started to use the drawitem event of the listview control and i am making improvement in that.
Thanks for your suggestions.
But could you please provide me with a link
where i might be able to draw a perfect rectangle for the items
using drawitem event?
Thanks in advance.

Examine properties of the DrawListViewItemEventArgs parameter that the DrawItem event receives.

hi,
Thanks for your suggestions.
i have drawn the image and the text using the properties of drawlistitemeventargs(thanks). but still i am not able to figure out how to draw the border for that item.
Could you please help me by suggesting some links?
Thanks once again.

The drawlistitemeventargs parameter called e has a graphics property which you use for drawing. So you need to call e.Graphics.DrawRectangle method to draw rectangle around the item. In order to pass the desired rectangle to this method explore e.Bounds property and e.Item.Bounds property. Hope this helps

Thanks once again.

I would suggest that this should be addressed on the project Forum on Sourceforge. I will say, though, that you will probably need CVS to get all of the files.

I have posted the question on the project Forum on Sourceforge, but there seem no one visit it and I downloaded source from CVS

I'm sorry. It seems as though the project is dormant then. I don't think anybody here will be able to help.

Hi,
I'm having a .NET 2.0 application with an application-scoped setting with a default value. Now I'd like to change this settings before starting the application (not in the source). How can I achieve this? I didn't find any file and in the .NET 2.0 configuration tool there's no possiblity to change the settings. I already added the assembly to the GAC and I tried to configure it with the configuration tool.
Thanks in advance, Tobias

Hi, does anyone know how to use GetAmbientProperty() to get a specific property from the container? I'm talking about custom properties instead of the colour, font etc...
I need to know this because I am trying to develop a custom control to be used in an application (written in VC++6) and the container provides specific details through the use of ambient properties. These details are account name, account number, version numbers and one or two more. I have the Dispatch IDs for these properties but I don't know how to retrieve them in C#.
Thank you for helping!

If no one knows how to use that ability in C# does anyone know how to do a similar thing in C#?

Hi,
I am sending data in the form of a COPYDATASTRUCT to a second application using the SendMessageTimeout() API function. The data is sent accordingly and the COPYDATASTRUCT retrieved at the other end using Marshal.PtrToStructure. I would now like to pass back a new COPYDATASTRUCT in the Message.Result, I do this with the following:
<br />
Win32.COPYDATASTRUCT cds = new Win32.COPYDATASTRUCT();<br />
cds.dwData = 1;<br />
cds.lpData = mydata;<br />
cds.cbData = Win32.GlobalSize(cds.lpData);<br />
<br />
IntPtr pResult = Marshal.AllocCoTaskMem(Marshal.SizeOf(cds));<br />
Marshal.StructureToPtr(cds, pResult, true);<br />
m.Result = pResult;<br />
Now the correct IntPtr value is passed back in the result param of the SendMessageTimeout function but when I try to retrieve the structure using Marshal.PtrToStructure() all 3 members of the strucure are zero.
I'm sure I'm missing something obvious here but I've been staring at it for hours and can't seem to see the problem.

I'm guessing you are sending a WM_COPYDATA message (with your COPYDATASTRUCT) to the other application. In general, Windows keeps each application in it's own virtual memory space. This virtual memory space is completely independent of other applications. So if you allocate memory in application#1, then the pointer returned is only good for application#1.
If you look at the MSDN[^] documentation for WM_COPYDATA, the first line under Remarks states that "The data being passed must not contain pointers or other references to objects not accessible to the application receiving the data". Because pointers are only valid for the given application. You can pass the memory location (a.k.a. the pointer's value) to another application, but the other application cannot do anything with it.
To copy data back, you would have to send a WM_COPYDATA message back to the first application. You could also use named pipes[^], .Net remoting, or maybe this[^].
Take care,
Tom

Hi to all,
I am trying to delete all the files in a specified folder in my project. for that i have written the following function....
==============================================================================
Code
==============================================================================
public void DeleteTempFiles()
{
DirectoryInfo DirInfo = new DirectoryInfo(Server.MapPath("~/temp/"));
if(DirInfo.Exists)
{
foreach (FileInfo FI in DirInfo.GetFiles())
{
FI.Delete();
}
}
}
==============================================================================
But whenever i am running the program it gives the error as....
Error Deleting File or Folder
Cannot delete <filename>: It is being used by another person or program.
Close any program that might be using the file and try again.
.....
Anybody help me to solve this problem.

It means that the file you want to delete is in use either by your program or by other programs. If your program has an open handle to the file then close it.

Hy,
Try using this code
string[] files = Directory.GetFiles(Server.MapPath("~/temp/"));
foreach (string s in files)
{
File.Delete(s);
}
Hope it helps.

That will still suffer from same problem with files in use, or not?

It won't suffer any problem, because the application doesn't open the file, that's why I used the static methods of the Directory and File classes.

Nope, original code that enumerates over temp files and tries to delete them didn't open any files as well. That's not the problem. Problem is that OTHER parts of application, or other applications keep the file opened. File.Delete does pretty much the same work as FileInfo.Delete (both check permissions and then call Win32Native.DeleteFile, just look with Reflector).

It may not open the file, but it will still fail if some other process has a handle to that file. Specifically, it will throw an IOException.
