how is it possible to get data (information) from an
internet site and show it inside of my own program
which is a windows form application. tnx

Most obvious way is to use a WebBrowser Control: MSDN[^]
If that doesn't do it, what do you want to do?

If I am understanding the question right he will also need a GetStringInBetween method.
public static string[] GetStringInBetween(string strBegin, string strEnd, string strSource, bool includeBegin, bool includeEnd)
{
string[] result = { "", "" };
int iIndexOfBegin = strSource.IndexOf(strBegin);
if (iIndexOfBegin != -1)
{
if (includeBegin)
{ iIndexOfBegin -= strBegin.Length; }
strSource = strSource.Substring(iIndexOfBegin
+ strBegin.Length);
int iEnd = strSource.IndexOf(strEnd);
if (iEnd != -1)
{
if (includeEnd)
{ iEnd += strEnd.Length; }
result[0] = strSource.Substring(0, iEnd);
if (iEnd + strEnd.Length < strSource.Length)
{ result[1] = strSource.Substring(iEnd + strEnd.Length); }
}
}
else
{ result[1] = strSource; }
return result;
}
It is a very generic method you can find it anywhere on the internet, because why would you reinvent the wheel.

How can I use 3D modules(Such as DirectX or OpenGL)in my programming...Please guide
Best regards,
|
|
|
|

That's far too broad a scope for anybody to stand a chance of answering here on the boards. If you narrow the scope of your question, you might get more help. Beyond that, try to google for DirectX tutorials C# and OpenGL tutorials C#.

Hello
If I set some secret/sensitive information in AppDomain ...
AppDomain.CurrentDomain.SetData(SOME_SECRET_KEY, PrivateKey)
How can I protect it from third party dll loaded on demand? For example, in our application which hosts third party dll,
<br />
MaliciousLib = Assembly.LoadFrom(DllPath);<br />
oService = MaliciousLib.CreateInstance("xxxx.xxxx.xxxx");<br />
ISomeService Service = (ISomeService) oService;<br />
Service.DoSomeWork(...);<br />
Here, MaliciousLib can also access AppDomain and retrieves secret key.
I'm considering loading third party dll's into separate app domain (In which case they can't have access to the main AppDomain right...? In which case, next logical question - how 3rd party lib communicates back to main assembly... while it can't access main assembly's AppDomain variables, perhaps "function call return" would suffice ...)[^]
But I just done some testing, User dll methods can still access AppDomain.CurrentDomain!
<br />
oSecret = AppDomain.CurrentDomain.GetData("KEY1");<br />
Many articles discuss theories surrounding AppDomain, how one process can host multiple AppDomain and disaster occurring in one won't bring down the whole process - but really? Thought that's .NET v1 behavior - from v2 on disaster in one AppDomain will bring down the whole process. Also, regarding Get/SetData from security perspective, there's nothing on Google. From my experiment, there isn't any security control on Get/SetData![^]
So really how to protect main app from loaded third party components? Any suggestion?

Hi
Assembly.GetExecutingAssembly - can we get "Key" which signed the assembly?
I examined the internals of Assembly using Visual Studio Watch window, I found properties such as CodeBase, EntryPoint, Evidence, FullName, GlobalAssemblyCache, ImageRuntimeVersion ... but didn't find anything which resembles Key ...
Thanks

So, this is not going to work if intention of loading third party dll into separate appDomain is security. Not to mention, there are ways to enumerate app domains in the executing process[^]
Any suggestion how we can save sensitive data in AppDomain (using SetData/GetData) "safely"!?
Thanks

Do not repost[^], it is rude. This might be urgent for you, but not for the people who volunteer their time.

I would like to display a picture in my WPF application, where the picture is loaded from a resource file. I'm not interesting doing this with C# code, only with XAML code. But I have no idéa how to pull this off. Please help me.
This is what I have done:
1) Created a new WPF application called: WpfApplication1
2) Created a resource file called: Pictures.resx
3) Added the picture into the resource file
4) The picture is called: CELabel, in the resoruce file explorer window
5) Automatically a folder in in my application is created, called Resources, containing the picture: CELabel.png
Now I would like to code the appropriate XAML code to display the picture. So I try this:
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<Image Source="/Pictures/CELabel.png"></Image>
</Grid>
</Window>
And of course the damn compiler results in an error:
Could not find a part of the path 'C:\Pictures\CELabel.png'
Yes, of course the resource file is not recognizable in the XMAL editor and then my picture cannot be loaded.
How do I pull this off? I'm sure this is rediculious easy when knowing how...

You've stated you don't want to do this in C#, so why ask it in the C# forum? You should ask WPF questions in the WPF forum.
