Initially I thought that the Show and Hide methods of TabPage would do the trick, but it doesn't seem that way.
You could probably achieve what you want to do by first creating your TabPage objects and then call TabControl.Add and TabControl.Remove to add/remove (show/hide, enable/disable) the tab pages you want.
This is not the most elegant solution though, but it will solve your problem 
Good luck!

Interesting. Do you mean you don't need so many tabs? Cuz, first, when one tab is showing, the others are hiding; second, tab pages can be removed if not needed.

I have developed a windows service in C#, however, when I start the service. I get the error detailed below. Can anyone help solve this problem?
Could not load file or assembly 'MySql.Data, Version=1.0.7.30072' or one of its dependencies. The system cannot find the file specified.

Hi,
I guess you implemented something with MySql. The service needs the assembly "MySql.Data.dll" within the GAC. Try to register the assembly there and your service will start (hopefully).

You sure do, as you seem incapable of using your own abilities.

Wrong site. Try rentacoder.com, they do your work for you. The idea of CP is to answer specific problems, not provide free code for people to pass off as their own work, either for college or when they have assured a client they can do it but haven't got a clue.

- Dont put "Urgent Help Required" or somesuch. It's in the FAQs/ How to post a question sticky at the top of the board
- Don't expect us to supply you with source code. Describe your problem and what you have tried. It's in the FAQs/ How to post a question sticky at the top of the board
- You can't really expect anyone to provide an entire system for you? If this is a college project, we should get the credit (and qualifications) for our work, not you, also if you don't do it yourself you won't learn anything. Assuming it isn't a college project this is, after all what you are getting paid for , so anyone writing the system has a reasonable expectation for the same

Hi,

Btw. this is an C# forum, and you posted some VB code. Also try to not double post.

I have created one text file in File Contain -> "abc or some value"
Account :LocaSystem
protected override void OnStart(string[] args)
{
if (!File.Exists("C:\\DevLog.txt")) {
EventLog1.WriteEntry("File Not Exist"); 5. }
else {
StreamReader sr = new StreamReader("C:\\DevLog.txt");
string tempstr = sr.ReadToEnd;
if (string.IsNullOrEmpty(tempstr)) {
}
else {
EventLog1.WriteEntry("Get File Name");
st = tempstr;
}
sr.Close();
}
}
the error msg is:---Service cannot be started. System.IO.FileNotFoundException: File not found.
I think you get clear idea about problem ...
Thank for reply

So its not necessarily that it can't read your file. Comment out all your code to do with the file and just write a message to the eventlog to show your sevice is working. Then you will make some progress.
There should be no problem reading a file, many services are file watchers, waiting for files to process.

Without File handling code it will working properly and also get proper eventlog up to the File.Exist()
Thanks for reply

So now try just checking for file.exists and logging a message. Put it in a try ctach so you can log the full exception details and that should give you some pointers.
Really, this is a basic programming technique for trapping/tracing errors so you should be able to properly identify where it goes wrong and also get the full error message as to why.
