Hi,
My situation is this, I have 3 comboboxes (drop down list only, not editable), and If the user changes the value of one of the, the other two should change too.
I have used the SelectedIndexChanged Event successfully to update the other two comboboxes. But I have 2 issues with it, first: The code is not pretty, I have to repeat the same 3 times and secondly everytime a call is made to one combobox's SelectedIndexChanged event the other are called too because I update the indexes of those too in the first call. I know it's kind of hard to understand like this, so here's what I'm doing:
private void SubNetCountCombo_SelectedIndexChanged(System.Object sender, System.EventArgs e)
{
HostCountCombo.SelectedIndex = SubNetCountCombo.SelectedIndex;
newsubnetmaskcombo.SelectedIndex = SubNetCountCombo.SelectedIndex;
}
private void HostCountCombo_SelectedIndexChanged(object sender, System.EventArgs e)
{
SubNetCountCombo.SelectedIndex = HostCountCombo.SelectedIndex;
newsubnetmaskcombo.SelectedIndex = HostCountCombo.SelectedIndex;
}
private void newsubnetmaskcombo_SelectedIndexChanged(System.Object sender, System.EventArgs e)
{
SubNetCountCombo.SelectedIndex = newsubnetmaskcombo.SelectedIndex;
HostCountCombo.SelectedIndex = newsubnetmaskcombo.SelectedIndex;
}
I thought of using a bool variable as a switch, so that everytime I enter each of those events it turns true and when it goes to the other methods I use an if to check for that variable, if it's true I just get out. But it's still not pretty... So.. I'm not sure if there's a better way of accomplishing this..
Thanks!

If any selection will change the other two,. you'll get into an infinite loop, unless you set some sort of flag which will tell the event handler not to do anything. You can also put all of these into one event handler, and just have it check which control it is working with, and then set the other two.

mmm.. As I said, any selection changes the other two, But no, I do not get into an infinite loop, It only repeats two times the events and then gets out, but you don't notice it. It's not like it slows down the program or anything.
And about the flag, that's what I said in the end of my comment, I used it, but I just don't like the way it works. I want to know if there's another way to accomplish this, without:
1. Having to use a flag.
2. Having to "repeat the instructions" as I'm doing in the excerpt I pasted here.
Thanks

Well, you've listed the only options. Either have one event for each, or one event that all three use, that's all there is. As for the flag, I'd have expected code that changes the selected item on the other two, to cause events to fire over and over. If that's not the case, then that's fine, you do not need a flag.

Hello,
I have a pdf file that has the whole help stuff in it. Based on the helpId(Which form the user has selected) I should display the correct help page.
Will this below code serve my purpose?
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.FileName = "Guide.pdf";
startInfo.Verb = helpId;
System.Diagnostics.Process.Start(startInfo);

This is programming, it's not black magic. You can't just go around making stuff up and expect it to magically do what you want it to. Instead, you should use reference books and google to research the tools you are using.
No. Of course not. You've taken a random property and tried to make it magically do what you want. The verb is a predefined term like 'run' or 'print' that tells the process what to do. There is no way that I know of to make a PDF open on a specific page. You'd have to read the Acrobat documentation to see if it's possible to pass any parameters to Acrobat, to tell it what page to open. As you appear incapable of research, I'll tell you that Arguments is the property on ProcessStartInfo you use to pass an argument to a program. But, you need to find out for yourself if Acrobat will take an argument to do what you want it to.

Those libraries are not cheap. What's the bet this guy is only interested in free solutions ?

I don't think you can do this using PDF files. If you can make your help files to a CHM file, work with Help.ShowHelp()[^] method by providing appropriate HelpNavigator value.

Hello,
I am using a MSAccess database date entered into the database are Medium date format ie. dd-mmm-yy format. But when the data is pulled from the db and shown into a datagrid, it's like mm/dd/yyyy hh:mm:ss. But I want only the medium date that is dd-mm-yy format(18-Aug-09). Please help.
Thanks in advance.

Any half decent database, stores a date as a date. That means, it does NOT store a string in any special format. It stores actual date information. So, in C#, you will end up with a DateTime object, instead of a string. And you can format that any way you like.

Actually this happens as your Localized regional datetime settings is dd-mm-yy.
To format use
DateTime.ParseExact(datestring, "dd-mmm-yy", new CultureInfo("en-US"))

If it's that important, you're best source of information is going to be the people who wrote the library. I'm guessing that would be Infospace.

This may be urgent only for you. And putting this in subject line is considered as rude.
