No, there is no premade assembly that wraps GhostScript. Various people have built their own by P/Invoking the hell out of the GhostScript .DLL's, but I haven't seen any wrapper publicly available.

I have a dll with about 10 embedded images in it. I would like to pull these out and load them when an event is fired(not all at once )but which ever one is needed depending on the user selection.
My problem is I have absoulutly no clue how to go about this even after making the reference.
Also I don't know that the dll was built properly. I created a resource file and added all the pics to it ( paths) and opened a blank project and added the resource file and built the proj as a class lib.
Also I created an empty proj and added all images, changed their propertys to embeded types , and built the proj as a class lib.
Both files are the same size 236kb. Still I can not "Get" the images out of the darn dll.
Any help , links , answers would MORE than apprieciated !!!
Thanks in advance,
Billy
I wish I could help instead of asking for it !
Can I open that beer for you ?

You need to create a ResourceManager object and use it to pull the images from your assembly.
See this[^], this[^], and this[^] on MSDN.

Our scenario is:
Various business objects on server using interfaced-based remoting being called by a thick Windows client.
In some situations, instead of receiving a "normal" exception or one of our custom exceptions we receive the following:
"See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.
************** Exception Text **************
System.IO.FileNotFoundException: File or assembly name Product, or one of its dependencies, was not found.

at System.Windows.Forms.ControlNativeWindow.WndProc(Message& m)
at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)"
I'm 100% percent sure that is not a missing dependancy - else nothing would ever work.
We have also been seeing this type of error from other assemblies.
Has anyone come across a situation where the DLL throws this error instead of a standard .NET exception?
EDIT:
I get a proper error while running in debug inside VS, but get the above error while running on our test machine.
Same build and same user, but different error...
Cheers,
Simon

Hello,
I've coded my own NumericTextBox. But there's a little feature I want to add: If you try to enter a character in the TextBox, this very typical sound should be played. But I don't know how I can do this.

If you've done this correctly and your already filtering out the incorrect key presses, you could just P/Invoke Beep in the Win32 API.
[DllImport("kernel32.dll", SetLastError=true)]
static extern bool Beep(uint dwFreq, uint dwDuration);

Hi every body!
My company wants to write a chat program. There will be about 300 people using this program. I see that we can use remote object technology to write this program. But I don’t know whether I will have to face with any problem when I deploy this program, what is advantage, disadvantage of the technology.
Could you give me some opinion?
Should I use remote object or socket technology?
Thanks a lot!!

It really doesn't matter which one you use. For a chat program, it's just a matter of preference, neither is harder than the other to implement, IMHO...
Why would your company want to write a chat program for internal use, when there are tons of them on the market that would probably cost less, off the shelf, if not free in some implementations, than paying you by the hour to write it?

I am trying to pass an Int32 array from C# to C++ COM object but am getting E_UNEXPECTED error from SafeArrayAccessData(…) call.
From C# I pass 'ref object' where the object is my Int32 array, and my COM object receives it as a VARIANT*.
Thanks for any suggestions

Hi,
I am looking for a recommendion a good utility for creating typed collections in C#, preferably a plug in to VS.NET. Could you let me know if you know of any good utilities?
TIA

nice of you to share us the solution you found..
a small note :
in the .net framework 2.0 collections will be available as templates.So we'll have better performance since there will be no casting and boxing/unoxing.

Your welcome.  Actually, I'm still hoping for a recomendation because that one I mentioned is a little quirky. But the article itself is quite useful for a starter in to VS Add-ins.

Except that what everyone knows and loves as templates is called "generics" in .NET 2.0.

sorry, but i meant how to deploy an application.exe . there are tow application: the first application deals with some Xml files, but this files are them selves generated by a second application, so can i use this last one (second application) to generate the xml files (already done) and deploy the Firstapplication.exe that use the generated xml files and so create a firstapplication Setup.exe without using the setup wizard.

Morning All,
A couple of questions for any remoting gurus out there!
1) How do I return an instance of a different type of object from a server object back to the client
eg: (Psuedo Code!)
ServerObject2 ServerObject1.GetAnotherObject()
{
return new ServerObject2;
}
2) How do I enable two way remoting so I can send an object created on the client back to the server
eg: (Psuedo Code!)
void ServerObject1.UseAClientObject(ClientObject oClientObject)
{
this.ClientObjects.Add(oClientObject);
}
Cheers - James!

i need to call a function of a C DLL. the function is declared as
_EXTERN int __stdcall MyFunction(HWND hWndParent, LPTSTR lpszRow1, LPTSTR lpszRow2, LPTSTR lpszRow3);
so i've defined in my c# code
[DllImport("library.dll", CharSet=CharSet.Auto)]
protected static extern Int32 MyFunction(int hWndParent, StringBuilder lpszRow1, StringBuilder lpszRow2, StringBuilder lpszRow3);
in the C/C++ code i have to pass 3 strings of 42 chars (8-bit each) and the function fills the tree with some names.
in c# i've created 3 StringBuilder variables and initialized to 42 of both length and max capacity.
When i call the function the strings are written but the problem is that each char of the StringBuilder is of 16-bit so 2 characters are in one.
Is there a way to extract each single char or to define a StringBuilder of 8-bit elements? I've tried to use string and LPTStr parameters for the function but the DLL doesnt seem to copy anything in my strings.

Hello and sweetest wishes for everybuddy,
As part of my project in one ASP.NET server application I have to check if some valid IP client node (wich contains an ASP.NET web application itself too) is currently connected to internet or not and decide based on this state.
One way I think about is to put a socket server on the client node and send a connection request for that to see if it will be successful or not.
I wana see other programmers' experienses and suggestions if there is some better way for that or some special pattern in the socket approach.
Please note I need acceptable speed to see check result.
Thank you so much,
- den to fly

hai there,
i have a block of code that will generate indexoutofrange exception.
but on catch block i will use Exception (super).
in both cases exception will catch.This is one situation where i know the chance.
My question is what is the performace and resource usage variation if i use Exception Class insted of indexoutofrange on above situation.

There is no difference because the exception chain won't be walked until an Exception actually happens. When the chain is walked, the exception that was thrown will be compared to the narrow exceptions first to see if there is a handler, if not, the more general exceptions will be checked locally first, then following the call chain, keep going until a handler is found or not.
If your trying to determine which Exception class to catch, either IndexOutOfRange or Exception, to see which one is faster, the answer should be neither. IndexOutOfRange MIGHT have a very slight speed advantage. You'll just have to test it to find out. How long does it take to catch 100,000 Exceptions compared to 100,000 IndexOutOfRange exceptions?

Hi every body!
I'm learning about remote object.
In a sample i'm learning there a statement
Type.GetType("SharedAssembly.SharedObj,SharedObj")
all time when this statemet is excuted, it return null
SharedAssembly: namespace.
SharedObj: a class in above namespace.
Could you tell me how can i fix it?
Thanks!

Type.GetType("SharedAssembly.SharedObj, SharedAssembly");
For remoting you'd use <a href="http://msdn.microsoft.com/library/?url=/library/en-us/cpref/html/frlrfSystemActivatorClassGetObjectTopic.asp?frame=true" target="_blank">Activator.GetObject</a>. See the example code in the MSDN overview of Client Activation.
