Try to use Process.Start Method (String, String, String, SecureString, String). You should have username and password, anyway...

Please post the code for impersonation. You might not have a good handle

Oh, I understand now. You are trying to run another read on same connection !
Read about MARS: http://msdn.microsoft.com/en-us/library/cfa084cz(v=vs.80).aspx
And don't mess with dtStudent in loop.

Catalin Serafimescu 25-Jan-12 8:26am View

Paste the new code here.

See this example: http://msdn.microsoft.com/en-us/library/9kcbe65k.aspx. You need to open the connection, though - my bad.

Seriously, don't start with keyloggers or any advanced things. Start with basics, it will help you later.

Catalin Serafimescu 16-Jan-12 9:25am View

I can't help you with this, but I think you need a public IP address. Replace the computer name with IP address in WSDL bindings and I think it should work.

First read about application design - MVVM, Domain Driven Design. Otherwise you are going to mix data with presentation and business logic and the maintenance/development cost will blow in the sky.
Then start with simple WPF - Visual Studio is enough. If you separate correctly the presentation layer (GUI), then you can skin it nicely with Blend. Otherwise you are going to spend lot of time in learning Blend and fixing GUI problems instead of focusing on application logic.

"Premature optimization is the root of all evil".
I think you want to say 'my application has a reference to DLL'. I think you open the player in a child form and want to release the libs when you close it. Loading and unloading libraries is time-consuming. I think you should not do this unless you have a very strong reason.
There might be another way, but I'm not too sure and introduces another layer: if your DLL is native (unmanaged), you could write a managed C++ wrapper over it and you load it dynamically, then you release it. It might work.

I suspect there is thread remained alive. Please provide more information about what are you doing.

Catalin Serafimescu 12-Jan-12 16:34pm View

This involves that forms knows one about another. It's not a good technique, you should review your design.

Catalin Serafimescu 12-Jan-12 16:28pm View

The server is conceptually separated from host. You write a server and you host it. You can host a WCF server in any process: console/windows app, windows service or IIS. See http://msdn.microsoft.com/en-us/library/bb332338.aspx
How to expose your endpoint it's another matter. You don't actually need IIS to expose a WCF service, but I think you'll need a static IP.
On another topic, you can build a web application to send messages/commands to your service.
It would be useful if you explain what you did.

Catalin Serafimescu 12-Jan-12 16:17pm View

The objects needs to be marshaled. And you can't do that with any objects. And, compared with 'regular' programming, it's more complicated.
Also, from the name of the DLL I suspect this is some player. Not sure, but I think streaming is impossible between domains. In any case, I wonder why unload the player DLL...

I can help you with system and application design if you want. I'm very bored..

Catalin Serafimescu 10-Jan-12 8:34am View

Duplicate question. See http://www.codeproject.com/Answers/311584/Find-tree-view-child-name. You are right about Name.

Catalin Serafimescu 10-Jan-12 8:34am View

Why are you duplicating questions ? I gave you the solution already: http://www.codeproject.com/Answers/311584/Find-tree-view-child-name
You must add nodes by specifying both key (name) and text !

Catalin Serafimescu 10-Jan-12 6:54am View

TreeNode.Find needs a key. You are adding nodes with text only, so key is empty.
Just give it a try.

Use the <pre>BackgroundWorker</pre> to run the compiler (pass parameters, etc...). Listen for <pre>ProgressChanged</pre>
In <pre>DoWork</pre> you create a <pre>Process</pre> (the compiler process) and redirect the <pre>StandardError</pre> and <pre>StandardOutput</pre> (see documentation). Listen for <pre>ErrorDataReceived</pre> and <pre>OutputDataReceived</pre> events using lamdas. When something comes in, call <pre>worker.ReportProgress(some_number, message)</pre>. You will receive the notification in <pre>BackgroundWorker.ProgressChanged</pre> on the GUI thread. Display the message in GUI.

It will take a while, hold on.

In fact, DPI might be different. Or, if app is a WPF it might layout differently the controls if the screen resolution is too small

Catalin Serafimescu 9-Jan-12 10:35am View

Usually web links are saved in Favorites. User can type CTRL-D and this is all.

Catalin Serafimescu 9-Jan-12 9:50am View

Sorry, but it does not make sense. Because you need to use only one value as a key, not all data you display in datagrid. Set the CB ValueItem and DisplayItem to columns you want to show.
If you really want to do it your way, you need to implement your own control. But I strongly suggest to review your GUI design.

Catalin Serafimescu 9-Jan-12 7:11am View

Are you using a font type which is not installed on the other desktop ?

Catalin Serafimescu 7-Jan-12 16:02pm View

There is no such thing lilke '.net 08'.
Try to install .net 4.0 in the 'other machine'. And check Event Log. Provide any error you might get.

Catalin Serafimescu 7-Jan-12 4:57am View

You should provide more details. What means 'it's not working' ? What error you get ? It's the service installed ? Did you checked Event Log ? BTW, what's '.NET 2008' ?

Catalin Serafimescu 6-Jan-12 9:52am View

No, I'm saying that you need to handle the case when the user deletes characters. And this can happen anywhere in text.
Let me give you an example:
user type i, a (has я), type - (has иа), corrects (type Backspace - this is the most used behavior when you do a mistake when typing) => you need to revert back to я.

Catalin Serafimescu 6-Jan-12 9:15am View

I found akward to obtain [иа]: type i, a, replace i&a with я, type -, replace я with иа. In my case would be: иа = i+a, я = i+a+- & replace.

If you want to keep your logic, then use only the replacement section from my code. It will become a little more complicated, I think.

Homework: handle Backspace & Delete.

BTW, user can move caret and type. Then the select at the end is not OK, but I skipped it for now.

Don't use TextChanged, you will get infinite loop.

BTW, most human friendly solution is to type using Cyrillic on a Cyrillic keyboard

Catalin Serafimescu 6-Jan-12 6:49am View

I was thinking to write all in Latin and interpret it. Like 'iazik' and 'ia-zik'. I'll have a look

Catalin Serafimescu 6-Jan-12 6:28am View

I think I understand now. You want to type ia and ia- and display different things in the same text box. I think you can handle the KeyDown event and analyze the input. You can analyze to the last space or you can use RegEx to analyze all text (but this might become slow for big text unless you do the same thing to the last space). I think you realize you need a full dictionary mapping between input and output, right ? I found a bit strange to type Latin and display Cyrillic, but if this is what you want... Let me know what you prefer and I might be able to help you.

Catalin Serafimescu 6-Jan-12 6:04am View

Well, I don't think you can render same sequence in two ways in the same context. Something must differentiate between the two choices.

Catalin Serafimescu 5-Aug-11 15:10pm View

CodeDOM is only for .NET-based languages (C# and VB, I think). And it's slow (search google).
For anything custom you need a parser and an interpreter.
Not necessarily useful for this question, but it's good to know available options. BTW, to create a custom language is not trivial, but it can be done, if the project worth it.

Catalin Serafimescu 28-Jul-11 12:43pm View

What do you mean by 'Embed the Referenced DLL in my Executable file' ? You want to have only one file with everything ?
You can add a post-build step and re-register the dll's on GAC when they are rebuild.

A nice analysis about singletons: http://www.yoda.arachsys.com/csharp/singleton.html

Or, a more elegant and flexible way, though complex: Dependency Injection, like Unity ;)
