To answer your question about cleaning up the icons, no there is no way to force the Tray to clean itself up.

The only way i will refresh is if you point your mouse to the "destroyed" icons...

Tell the OP, not me. I already know that.
He was referring to a programmatic way of forcing the cleanup.

Hi, I have created the following program first as a console application. Then I created a windows application and copied the class data there. It is shown below. In the console application, I have used the printData() method to output the data of an instance of a Person or Athlete class. I want to do the same, but now that output should be in the label.
Any help would be appreciated.

I am trying to open a .sln in vs 2005 but the error is:
The application for project ....csproj is not installed.
Make sure the applucation for project type (.csproj) is installed.
Thanks

I've never seen that error before, but it looks like it wants to open a C# project. I'm guessing it thinks that C# isn't installed. You can go to Add/Remove Programs and select Visual Studio 2005 and there is a Change/Remove option. Click that and you will get a "Maintenance Mode" installation wizard. It should be able to install or repair the components you need.
Unfortunatly, if that does not work, then I don't know what it could be.

I've actually seen this error when you've got a corrupted VS install. There is some fix as I recall, but it's probably best just to do a clean install of VS.

hey guys!
how do u loadin gthe resource string in C# 2005?
thanks
|

If you are using Visual Studio then it makes it very easy. When you create a resource file, it puts a nice auto generated code file behind it containing one class, that class has the same name as your resource file, and it contains lots of static methods. Each method name corresponds to the identifier you've given each string. So, say you've named your resource file MyReources.resx and you have a string named "MyString" you can access it in you code like this:
MyResouces.MyString

Hi,
I'm trying to get all the paths of the open applications in a C# program.
What I need is only paths of open windows(the ones the "Task Manager" shows under his "Applications" Tab),i.e. the windows that are shown in the Taskbar.
For example if there is only 1 Word file open, named "1.doc", I need it's full path. (for example : "D:/Temp/1.doc").
Thanks, Gal.

So what you're asking is to get the full path of opened documents, not the paths of applications.
For starters, you can get the running processes (which includes applications) using the System.Diagnostics.Process.GetProcesses() method.
But from there you're on your own. There's nothing built into the framework (nor the Win32 API, AFAIK) that will let you see which document is opened by a program, simply because there is no way of letting Windows know when an application has a document opened. Windows does know when a file is opened, so you might be able to find some Win32 APIs that you could query to find the opened documents of the system.

Hi,
I do need open documents but also open programs, which I opened (i.e. if the Visual .NET is open, I need the path to it's .exe file also)- all open windows(windows of documents and programs).
You said windows does know when a file is open.
I looked in the System and Environment objects but didn't find anything yet. From the process list I couldn't get anything usefull.
Do you know where windows keeps it? what Objects besides the 2 I mentioned might keep that kind of information?
Maybe the Task Manager keeps it since in his application tab it does shows exactly the open windows, though I couldn't find any API related to the Task Manager, nor files with that information that the Task Manager manages.
Thanks,
Gal.

Task Manager sees Processes, not open documents. The only reason TaskManager sees those is because the application treats each open document as a seperate process.
There is no API function anywhere that will tell you the open documents of any application. That has to be exposed by each individual app, and even that isn't done consistantly. This means you'll have to write code for every different app out there (Good Luck!) to enumerate their open documents.

Hi all,
I am using RSACryptoServiceProvider and RSAPKCS1SignatureFormatter to create private/public keys and signed data with the private key (later decrypt using public key).
i know how to get teh Module and Exponent inorder to send and use it later.
but i also want to get the private key so i can use it many times more.
now i use this code:
byte[] mod=RSA.ExportParameters(true).Modulus;
byte[] exp=RSA.ExportParameters(true).Exponent;
RSAParameters RSAKeyInfo= new RSAParameters(); //create new keyinfo
RSAKeyInfo.Modulus=mod; //set the modulus
RSAKeyInfo.Exponent=exp; //set the exponent
and later i creat new key and import the modulus and exponent.
it is working fine for the public key but if i want to Sign again using that key , i get an exception saying that the new key do not contain the Priavte key.
what can i do? how can i get hold of the Public key?
Thanks alot,
Ran.

I intend to make a dictionary application. My problem is how to make my owner data file. My data file is too big. How can i can read it quickly at any position in file, what's the structure in file. Can you so some information involve my problem. Thank a lot
|
|
|
|

I guess you could make an index file that keeps track of where in the file each entry is.
The structure of the file?? That's entirely up to you. Start with what you're putting in this file, laying out the fields for what you're storing.
If you don't know this already, you're going to have a very hard time writing this app. I'd start writing sample applications that test writing, indexing, and reading your file. Do the research first to teach you what you need to know, then write the app.

Hi,
is there an AutoSave example to automagically safe a file at certain interval in time?
I tried use the Timer event but the problem is to tackle when the save-destination-time is due/passed.
I would like to skip looking into windows services as that would make it just 'too much'  )
Thanks.

Run a separate thread in the background
Thread thd = new Thread(new ThreadStart(autoSave));
thd.Start();
private void autoSave() {
Thread.Sleep(20000);
}

Thanx Willem, that is short and just what it should do )
|
|
|
|

Something that you have to consider, though: Using a separate thread to save the data means that you have to make sure that the operations on the data is thread safe, e.g. that you don't save the data in the middle of an update, and don't update in the middle of a save.

Yes, got that covered. Making a copy in memory of what i want to save first.
Thanks.

Any tips on repeating the thread eg. every 10 minutes?
|
|
|
|
|
Yep, add a while(true) construction around the code in the autoSave method
