Hi.
i'm developing an application in c#.
The first part is a typical application with forms, database queries, etc...
In a second phase, i need to design a panel with several buttons, with different captions, each button represent a complex vector shape with textures, for example a table, a computer, a tv...
When the user clicks on a button, a shape appears in a canvas. The user can drag and drop the shape and resize it.
If the user resize the shape, the texture must auto-adjust to the new size (tile effect).
In addition, it is necessary to implement a collision detector, to prevent "illegal positions".
f.e.: The table only can be placed in the floor and the tv only over the table, etc..
I need to chose an option (WPF, DIRECT2D, GRAPHICS CLASS ...)
1. ¿What option you recommend me?
2. Someone knows open source libraries or similar examples?
Thanks in advanced and sorry for my basic english

i am using the following code
System.IO.File.SetAttributes(Environment.GetFolderPath(
Environment.SpecialFolder.Cookies ).ToString(), FileAttributes.Normal);
DirectoryInfo directory = new DirectoryInfo(Environment.GetFolderPath(Environment.SpecialFolder.Cookies));
if (directory.Exists)
DeleteFiles(directory);
public void DeleteFiles( DirectoryInfo directory)
{
FileInfo[] info = directory.GetFiles();
foreach (FileInfo file in directory.GetFiles())
{
try
{
System.IO.File.SetAttributes(file.FullName, FileAttributes.Normal);
file.Delete();
}
catch (Exception ex)
{
}
}
foreach (DirectoryInfo dir in directory.GetDirectories())
{
try
{
DeleteFiles(dir);
}
catch (Exception ex)
{
}
}
}
This code is deleting all files in the Cookie folder but the problem is index.dat file remains there it gives error
Used by another person or program
What should i do to delete that file
Thanks

index.dat is a system file and should not be deleted.

Obviously they will, when you visit a website that uses them. However, your questions was about deleting index.dat, which has nothing to do with the cookies.

You can use windows API to delete all the cookies.
The functions below are useful:
FindFirstUrlCacheEntryEx, FindNextUrlCacheEntryEx, DeleteUrlCacheEntry.
They are defined in wininet.dll.

Ive now seen that when the process class is used as an instance there is a WaitForExit() method
but now i'm getting an error on myProcess.Start("ring.exe"); " System.Diagnostics.Process.Start(string)' cannot be accessed with an instance reference; qualify it with a type name instead "
here is the code
Process myProcess = new Process();
myProcess.WaitForExit();
myProcess.Start("ring.exe");
thanx

try use the following
//Wait for window to finish loading.
process1.WaitForInputIdle();
//Wait for the process to exit or time out.
process1.WaitForExit(5000);
.....

hmm... it seems WaitForInputIdle method only works with processes that have a user interface...
Alternatively i think u can do that using threading..i'm not sure

I'm wondering if anyone could help me in this one... I'm attempting to execute a simple Batch-File, and capture the output.
So far, I have something along the lines of:
System.Diagnostics.Process tyroTest = new System.Diagnostics.Process();
batchTest.StartInfo.FileName = Application.StartupPath + @"\myFile.bat";
batchTest.Start();
StreamReader sr = batchTest.StandardOutput;
MessageBox.Show(sr.ReadLine());
but am carrying on recieving errors like:
StandardOut has not been redirected or the process hasn't started yet.
As you see by the commented-out code, I've tried multiple variations...
Any hints, anyone?

You need to add these lines. Why don't you read documentation?
batchTest.StartInfo.UseShellExecute = false;
batchTest.StartInfo.RedirectStandardOutput=true;

Try adding batchTest.StartInfo.RedirectStandardOutput = true; before you start the process.

Thanks to both of you!
Working well now!

Hi All,
I am using VS03 + c# + MS ACESS databse.
In my application i am creating a CommonConnection.cs class where i store the path of the database.
From this class i am fetching the connection all the time.
But now i want to use app.config file for setting the path of the datbase.
Please tell me how can i store the path of databse in app.config file and as well as how can i fetch the value of databse path to any form.I also want to save datbase password in app.config.
Here is my code for store the path of database.
public OleDbConnection connection()
{
OleDbConnection aConnection = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\\Data\\Test.mdb;Persist Security Info=True;Jet OLEDBatabase Password=san7481");
return aConnection;
}
here i am fetching the value of connectionstring in form ,from class file.
CommonConnection objCI = new CommonConnection();
private void frmIrrigationTreeSpecifications_Load(object sender, System.EventArgs e)
{
OleDbConnection aConnection = objCI.connection();
}
Thanks in advance.

<appSettings>
<add key="ConnectionString" value="whatever" />
string connection= System.Configuration.ConfigurationManager.AppSettings.Get("ConnectionString");
I recommend reading the article I link to in my sig, you could have easily found this info with a google search.

Hello!
I am looking for some suggestions/tips for the following issue:
I have a C# Windows application having 1 form. In that form i have 12 text-boxes, 2 progress-bars, 5 buttons, status strip and 5 group-boxes.....as displayed in task manager, it is taking more than 25 MB of RAM! I haven't placed any code yet, any recommendation/tip/suggestion for the issue will be appreciated.
BTW, any idea how much RAM should it be taking?
Regards,
Adeel
Do rate the reply, if it helps or even if it doesnot, because it helps the members to know, what solved the issue. Thanks.

25 MB seems fine to me. Remember, there's a residual amount of RAM before you start adding stuff. A second form won't make it 50 MB.

Don't know why... :

When I try to drag one of my usercontrol onto the form, I get the following exception. But I could add the control onto the same project by opening it in mt friend's system. But coming back to my system it gives me the same error... what could be wrong in my system?
