You use the variable named com in OnComm event handler, but it's obviously defined somewhere else (at class level?). I'd guess that it's contents are not refreshed so you maybe getting the old response when a new event arises.

Hi to all!
The problem is still remaining. I'm going to tell you in a few points, what i'm doing.
The received data monitoring function is buffering the incoming data and when is received, it writes that data into a text file.
When i make the connection with the remote system, i receive the confirmation bytes and then, they're saved into the text file. After this, i'm sending a command to obtain my first packet from remote system and when i receive that packet, i want that to be saved in the same text file, from where i'm going to extract the packet counter to use in the rest of commands.
The problem here is that my program calls the function which is searching that packet counter before the data reaches the text file, and then appears the error: "Index was outside the bounds of the array."
I already tryed to introduce some Thread.Sleep calls, but is not resulting too.
Best Regards.

Another question,
Is it possible to make the buffer discharge rigth after receiving data without waiting until full message reception?
Best regards

Hi to all!
The problem is finally solved. A do-while loop with Application.DoEvents() and a FileSystemWatcher Object. In this way, i could monitor changes on the text file, and only when the packet counter was writen on the file, the catch packet counter routine is called.
Best regards.

Hi, I'm really new to C# so I hope everyone forgives if my question is a silly one. I'm basically a PHP programmer turned C# Programmer for a new project being developed at my office.
Here is what I want to do, I have an application that has some menu items on the top. Now when user clicks on one of the menu item, I want to show the form that contains the interface to be shown in the main form instead of launching a separate form.
I hope I made myself clear. Maybe an example would be helpful. Well here goes.
Example: There is a menu item named "User Management". When someone clicks that menu item the interface would show a list of users, their login details, position etc. Now what I want is that this information will be shown in the form containing the menu, not in a separate form launched when that menu is clicked. Since there are different menu items doing different things, the main form will probably act like a container of some sort that has a designated area where other forms ( or other controls ) can simply show up.
Thanks in advance for any help.

Instead of making forms, create UserControls, add them to the main form, and show/hide them as needed. For an example of what I mean, check out my wiard form article[^]. In that article, the various wizard pages are nothing more than user controls. For your needs, the forms would change based on the menu item that was clicked.

Thank you very much. I guess I can use that very well written article of yours as a guide.

If you want an SDI (single document interface) I would use some of the dynamic controls .NET provides and make the data "fit" into the main form somehow. If your main form had generic space for properties (i.e. a property table), fill the user data into there. All of the controls and layout panels in .NET offer some sort of on the fly data filling or layout changing. Add/Remove controls from parents, or make them invisible to build the UI as needed.
If you want an MDI (multiple document interface), which is little windows contained inside a big one, I would use a 3rd party MDI creator like this one: http://www.arstdesign.com/articles/sdimdiwizards.html[^]
Word is an MDI using many windows for your many documents or views of documents. IE is an SDI, using a tabs user control to show many layouts / documents.

Thank you for your reply. I guess I will use that app you linked to. Will have to go through a bit of testing to know which will serve me best. Thanks once again.

I have a simple PDF organizer I wrote for personal use and it loads pdf files using the ActiveX control. My problem is that when I load a password protected file and choose cancel when the password is requested the control goes blank and it will no longer load other files until it is disposed and replaced. Problem is there is no error or event that I can associate with this phenomenon to tell when I need to do this. The only other way around this is to create a new instance of the ActiveX control before loading every file. Anyone know what I'm getting at here and how to fix it?
Thanks.

Hi All.
I have a suggestion to write an application that installed on client pc and communicate with a VPN server.
User can connect via username and password and can send some request to server via the application.
For example they can ask from the server to unblock some special site for them,that usually is forbidden for other or another service.
In server Admin should to manage user request,user service,user info and so ...
I want to see if it possible and what type of programming i should to do?(socket programming,...?).
Thanks for any idea or help.

Hello everyone,
I have some python source code and I want to convert to .Net C# code. Any tools to recommend?
thanks in advance,
George
|
|
|
|
|
The only conversion tool is your eyeballs and hands. There is no automated conversion tool possible.
Your only other option is IronPython[^], which is a .NET CLR version of Python. Of course, there may be a fair amount of rewriting of your code to get it to work.

Thanks Dave,
I am confused about your solution of using IronPython. I am also new to IronPython, but I think the function of IronPython is to invole .Net code from Python code. Does it have function to compile Python code into .Net IL? Any more reference links?
regards,
George

What's to be confused about?? IronPython is a .NET CLR, managed-code verison, of Python. It's not to involved .NET in Python. It is a version of the language that cannot run without .NET. No, there is no possible way to convert the code you have to work under the .NET CLR, without rewriting it, by hand.

Thanks Dave,
I am confused about what do you mean "IronPython is a .NET CLR, managed-code verison, of Python. It's not to involved .NET in Python". I am interested in how IronPython works, does it compiles Python code into .Net IL code and then run them under .Net Runtime?
regards,
George

Just like C#, VB.NET, C++/CLI, ..., yes.
|
|
|
|
|
But what do you mean "It's not to involved .NET in Python"?

George

He means 'Yes'.

Wow your request is on every forum possible isn't it.
Such a tool doesn't exist, you're gonna need some help on this one from someone who knows both python and c#.
|
|
|
|
|
You mean convert the code manually?
regards,
George

what is the .xsd file in a C# project ?
Thanks...
|
|
|
|
|
Which one? It might be a dataset schema, it might be virtually anything
Be more specific.
Regards,
Lev
|
|
|
|
|
xsd files are XML schemas for datasets
|
|
|
|
|
What if I have a xsd file in my project for some xml-html transformations? Will it make it a dataset schema?
Of course not. It is not clear which file hung1984 means, that's why I asked him to be more specific.
Regards,
Lev
