hi,
I am working on a project related to packet sniffer in JAVA. afer a lot of research I found that this is not possible in java. Java simply does not provide such low level facilities.
A developer suggested me of developing it in some other language and then passing the info to a java socket wherefrom I ca read the contents.
Another suggestion was to use some proxy to divert port 80 traffic to some other port and then read info from there.
I have found nothing on the latter. can someone help me with how to build a sniffer in VB.NET to be run as a background thread which can pass values to java.
I am running out of time as the deadline is approaching.
Please help me out.

Since you running two completely different execution environments, you can't run the VB.NET process as a background thread to the Java application. But, you can expose a VB.NET component as a COM object and import that functionality in Java through its COM interface.
Heath Stewart wrote a great article on just that subject here[^] on Code Project.

I have a class library and i have built the class library. I am using the DLL of that class library in a project. When i use the function provided by that dll in debug mode i am able to see the code written. how can i prevent this . is there some other way of making dll in .net so no one else can view the code once it is built.and i don't want to place it in the gac.

Do you mean you can see your original source code? Or do you mean you can see the IL code? Also, you only mention a debug version, why are you distributing this? Debug versions are compiled differently so that it is easy for a debugger to interpret what is happening with application should it go wrong. You should use the release version.
If you need to obfuscate the dll further there is a basic obfuscator that comes with Visual Studio.

when i am using the dll in aother project on the same machine then i can se the code. but when i use the dll on other machine then i can't. i'll be using the release version. i don't know much ablout obfuscate, just that it helps in protecting intellectual Property . can u give me an example on how to protect my dll by obfuscation?

That is because you are using the debug version. I've said already that it contains extra information in it to assist debuggers to show exactly where errors are. Some of that information is the location with in the source code files of the code that it is currently running.

In the tools menu in Visual Studio you will have Dotfusticator Community Edition which is a basic obfuscation tool.

but i don't know how to use it (dotfuscator). is there any sample or tutorial on how to use it.

Has it occured to you to read the help files first? Load Dofusticator Community Edition, and go to the help menu. You have to learn to at least attempt to read the documentation before whining that you don't know how to use something. Then at least when you come to say that you don't know how to do something you can explain what you tried to do, what you thought the documentation meant and so on.

I have create a datagrid and placed a tablesyle within it, and have filled that with Data Grid TextBox Columns. I have been able to get my datagird to show tablesyles, now I'm trying to get the my datagird to automatically open my tablesytle with no luck is there anyway that this can be done through code or properties?
Anyhelp would be great
Thanks

Without seeing your code, it's impossible to tell you what you've missed. Part of a tablestyle is supplying the name of the data column that it's supposed to display for. But, like I said, with out the code...

Can someone help me out with this error. I would appreciate any help.

First, your XML didn't post correctly because you didn't check the box at the bottom of the post window, "Do not treat <'s as HTML tags."
Second, what's the complete exception message and on what line did the error occur? I really don't feel like trudging through that huge Try/Catch block you've got.
Third, you're doing too many different things in this Try/Catch box. Break this down into multiple Try/Catch blocks and reorganized the code into smaller logical blocks. The Message Queue stuff at the top should have it's own Try/Catch block. The Error Logging stuff near the bottom should have its own. And the stuff in the middle looks like it should be split into one or two more blocks, but I can't really follow what the code is doing very well.
Lastly, why are you converting a string to a string?
Catch ex As Exception
m_strTemp = Convert.ToString(ex.Message)
ex.Message is already a string, so your conversion code is completely unnecessary. Rookie mistakes like this make me wonder if you really understand what your code is doing.

Hi there! I am trying to put a regular HTML link into a VB.NET project I am working on. I would like to use Javascript's pop-up window command, but I don't know how to write it in such a way, that what I enter is how it would be interpreted. Does anyone know how to use Javascript's window.open() function to generate a pop-up window programmatically from within VB .NET. If so please let me know. Thanks for any help you can pass my way.

Hi there:
I strongly beleive there is a strange logical problem with the overall docking behavior of the dotnet controls. What a developer needs is that what control he docks first, gets docked first regardless of in what order the controls were added to the container. But dotnet IDE docks the controls in a specific order that somehow depends upon in what order the controls were added to the container. The worst is dotnet doesn't explains what is that specific order. Let me xplain the problem by an xample:
1) In any form, add a panel.
2) Create 2 label controls on the form called label1 and label2.
3) Drag label1 to the panel.
4) Drag label2 to the panel.
5) Set the Dock property of both to bottom.
6) Doesn't matter, in what order u perform the step 5, label2 will always be at the bottommost position.
Now repeat the same procedure as above, but change the following steps.
2) Create 2 label controls directly on the panel called label1 and label2.
6) Doesn't matter, in what order u perform the step 5, label1 will always be at the bottommost position.
SO u can clearly see that docking behavior is changed in both cases. In step6 of first one, label2 will always be docked at the bottommost position, while in 2nd case, label1 will always be docked at the bottommost position. Is this behavior justified and can developers rely on this type of uncertain behavior. Plz. comment on that.
The practical problem, i'm facing due to this uncertain and unjustified behavior is that:
1) I have made a custom container control, which has a label(acting as a caption). This label must always be docked to the topmost position in this control, so i have set Dock=Top for this label.
2) But due to dotnet docking behavior, when a user adds another control to this custom container and sets the dock property of that control to top, it gets docked at the topmost position and the caption label gets one level down, while it is not expected to change the position inside the control.
Is there another solution available, so that my label always stays at the topmost docking position.
There is anoher issue, at which i need ur comments, although i'm not sure whether its really an issue or not. The issue is based on the basic OOP principle of Composition. In original C++ or Java, when ur class(say ClassA is composed of two or more classes(assume its two classes named ClassP, ClassQ), then none of the classes ClassP or ClassQ is supposed to lose any of its functionality in any way when contained within ClassA. But in dotnet it happens. How?
1) Start a new Cutom Control Project.
2) To ur custom control add a label, that is supposed to act as a caption. Dock it to top.
3) Add a panel to ur custom control and Dock it to "Fill".
4) Build the project.
5) Add a new windows application project as the testing project to ur solution and to the form in that project,add an instance of ur custom control.
6) Run the project and u see the panel has lost its functionality as a container.Y??
In answer u may tell me that if i want my custom control to be a container, i should inherit it from ContainerControl Class. But no, the whole of the control is not supposed to be a container in my case, only the area that contains the panel, need to act as a container. So while talking about the basic Composition principles of OOP, the ClassP and ClassQ should not lose their functionality, but in dotnet panel loses its main functionality as a container.
If u feel these are the problems, plz. tell me how can i notify microsoft about that so that they corret these bugs in their next .net release.
PLZ. HELP ME OUT
