Awesome, ... Thanks.
When you say cap the input box's text, what does that mean ?
Does that mean i just give the input field the name of inputBox1.text ?
|
|
|
|
|
cap = capture
If the input box is named "inputBox1" then to grab the text inside it use inputBox1.Text which is a property of the input box control class that will return the text contained within it as a System.String object.
Same goes if you named your List view control "listView1" then to add the item would be listView1.Items.Add(new ListViewItem("string of the item contents"); that is if your listView1 was setup with one column of information...

What Exception are you getting?
Either f might be null, otherwise you may get any of the exceptions mentioned here[^]

Thanks for answering but my f isnot null.
The image/jpg is already in the folder and i am loading within my Picturebox Control and upon clicking on a Delete button I want to remove the control as well as its image from the sourcepath but i am getting this exception
The process cannot access the file C:\Documents and Settings\user\My Documents\Visual Studio 2008\Projects\bin\Debug\myTempDire\mainFolder\sFderName\images\2.jpg' because it is being used by another process.

Post how you are loading the image into the image box, by guess is that you did it via a image from file call.
So you'd need to close the stream to the file before accessing it.
I'd change it to the following:
When you load the image into the image box instead of pointing the box at the image. Read the image file into memory and inject the contents into the image box. That way the image box doesn't have a file stream connected to the file.

By any chance are you using Image.FromFile to load the image? If so, the file is locked until you dispose the image. You need to either, dispose of the image before you delete it or, use an alternative method for loading the image such as FromStream which does not lock the method.

hi guy, I am loading image in the picturebox control like this on form load event. but Still the file is gettting locked. I don't know where the problem is getting. Any help Thanks.
string sourceFile =imagefilepath;
using( Stream stream = File.Open( sourceFile, FileMode.Open,FileAccess.Read, FileShare.Read ) )
{
try
{
Image image = Image.FromStream( stream );
stream.Close();
stream.Dispose();
pictureBox1.Image = image;
}
catch( Exception ex )
{
MessageBox.Show("so ");
}
}

That code should not give you a sharing violation when trying to delete the file further on. If it does, first make sure nobody else is actually using the file or keeping it open (perhaps not your application at all - or another part of it). Try using filemon (google that) to see what happens.
Some thoughts, however:
1. Make sure the picture box isn't still holding a reference to your image when you dispose of it. Otherwise, you will crash (either with an exception or with strangeness - this will depend on the current mood of your GDI). Always set pictureBox1.Image to null before you call image.Dispose().
2. You are calling stream.Dispose() even though you're in a using block for stream. Don't. The using block does that for you when you exit it - regardless of exceptions or whatever else may happen. That's the reason using blocks exist. Also note that stream will close itself when it gets disposed (unless you do it first), so the stream.Close() call can be dropped as well.
Later,

Hy there,my problem is this: I have an image in my project resources,and a control that has an Image property set to that image. At runtime,I want to know what image is in that property. So i say
if(image == Properties.Resources.img1)
do something
I know that that is the image in the property,so why isn't it working?

System.Drawing implements neither the == operator nor the Equals() Method. So therefore it inherits the Equals() implementation from Object which checks object references. And so it fails. Using the == operator on an image is rather absurd anyhow. If it's an issue, you'll have to implement your own Equals or == routines and check the pixels one at a time, or use the object references to your advantage.

Any idea how to convert strings like "Tuesday 1st April 2008" to a DateTime.
I have tried DateTime.TryParse with different CultureInfo, without result

Thanks
Useful tip, but I was not able parse the date
DateTime dt = DateTime.ParseExact("April 1st 2008", "MMMM dd yyyy", new CultureInfo("en-US"), DateTimeStyles.None); //Failed
DateTime dt = DateTime.ParseExact("April 1 2008", "MMMM dd yyyy", new CultureInfo("en-US"), DateTimeStyles.None); //Failed
DateTime dt = DateTime.ParseExact("April 01 2008", "MMMM dd yyyy", new CultureInfo("en-US"), DateTimeStyles.None); //Succeeded
Any idea what formatstring to use ?
I could manipulate the string before parsing, but I'm parsing 8 different languages with different date format :-/

I don't think it's possible to have one generic format for the above examples.
Either some manipulation and FormatException handling is going to be required, or you're going to have to force them in your UI to enter data in an acceptable format by either separating the day, month and year fields into separate controls or using a DateTimePicker or something similar.
The second two examples shouldn't be too hard, but the date suffix in the first does not appear to be included in any of the custom format mechanisms - unless it's possible to use a wild card for the two characters?
It may be easier to create your own control that can handle the 8 different language formats - that will give you more flexibility if more are required later.

Guess I have to do some string-manipulation.
My app reads the dates from different sources, like word, excel, text or xml files, so it's not possible to solve this by UI changes...
Thanks

I have a problem while trying to execute a delegate in a different thread.
I have my application and autocad that has loaded my .net-dll.
I created a named-pipe-server (in an own thread in the dll for autocad) and send messages to it from my application. The thread with the server watis for the messages and executes a delegate on receiption. The method in my class (in the dll) is called and I can show it with a messagebox.
Till here everything is fine.
But now I want to open a new file for autocad and I try to use the regarding method-call (AcadApp.Application.DocumentManager.Open(file)). But here is the problem. I get an exception about internal error or wrong context. I'm still in the thread-context of my listening server and I think that is the problem. But how can I execute a function in the autocad-thread? My initialization-function that creates the listening-thread is executed in the autocad-thread-context so I can get Thread-object or whatever is needed.

You can try using MethodInvoker inside your thread to invloke the function in another thread.

How does it work? Can you give me a sample? As you see I tried something but it doesn't work.
my code:
class IPCMsgHandler
{
private Thread listenThread = new Thread(ListeningThreadFunc);
...
public void Start()
{
listenThread.Start(this);
}
private static void ListeningThreadFunc(object data)
{
IPCMsgHandler helper = data as IPCMsgHandler;
...
MethodInvoker mi = new MethodInvoker(helper.OnMessage);
mi.Invoke();
...
}
}
public class AutoCADApplication : IExtensionApplication
{
IPCMsgHandler helper = null;
public void Initialize()
{
this.helper = new IPCMsgHandler("AutoCAD-IPCServer", new IPCMsgHandler.MessageHandler(this.OnIPCMessage));
this.helper.Start();
}
private void OnIPCMessage()
{
return;
}
