Weird. You should buy a beginners C# book and read it.

When I've done this, I've wrapped the calls to getting resources from the application in a method so I pass in the name and get out the image. Beyond that, you could use useful variable names. What on earth is Plugin, and why do you create one every time ?

hehehe, I can usualy write C# code.. I wrote a game emulator with C#..
This is my first attempt at writeing an image viewer and bam i'm having issues weird..

and plugin is the Class.cs that contains information, like the public int for what the Start Image number is, the Extention of the image, ect..

Then you wouldn't do nextImage = nextImage++;, you would just have nextImage++;

Furthermore, you stated (unless I misunderstood) that the Plugin instance you create each time the method is called contains the count for nextImage.

Fair, but then wouldn't you have

plugin p = new plugin();
p.nextImage++;
this.nextImage = p.nextImage;

Without seeing your code I think there might be some confusion as to variable scope, as well as class / object variable names. All in all this code is very hard to read, and impossible (for me) to figure out what it is you are trying to do.

I'd say go for that book.

I find that hard to believe. If that is true, you've learned some things, but missed some basics. Go back and buy that book.

So, it's reset to 0 every time because you create a new object. Again, buy a book.

Hi How can i use a function in classes when that function exist in codebehind of a form ?

and :

I use -private void checkBox1_CheckedChanged(object sender, EventArgs e)- in codebehind;
Now i want to use checkBox1_CheckedChanged in another event again;
but compiler doesn't allow me and compiler error me that argument is necessary.
What should i do?

You must pass the correct argument to the method or of course you'll get compiler errors.

A better approach may be to create a method that can be called from the CheckChanged event

Use checkBox1_CheckChanged(Methis, EventArgs.Empty); to call that method

Those are partial classes and can be called as any other function provided the form exists.

Only ASP.NET has codebehind.

You should post code and the actual error message so we can work out what you mean. Use this and EventArgs.Empty to call an event, but I think it makes more sense to factor out the common code to a method.

There is a problem in the first line. I leave it up to you to find and fix it.

BTW: "File in use by another program/process" isn't the best Windows message, it may well be (most often is) the same process causing the situation.

Outlook 2007 Addin install problem..

I seem to be having trouble install these addins. I followed a tutorial on how to create a windows installer file for it (http://msdn.microsoft.com/en-us/library/cc563937.aspx[^])

Well when I install it, it installs but when you launch outlook you get an error about it not being able to find the vsto file. So I remove the addin from outlook because it isn't working, then I go to where it installed and double click that file to install it. Then it gives an error like this:

System.Net.WebException: Could not find file 'C:\Program Files\Arkansas Department of Emergency Management\ADEM Application - Outlook Plugin\OutlookPlugin.XmlSerializers.dll'

Now this plugin does use a web service but why is it giving this error?
Also on my computer it works fine when I right click on the setup project (in VS2008) and click install. Everything works great if I do that! But obviously I can't install VS2008 on everyones computer and install it that way LOL

Any help would be great.

BTW where is this XmlSerializers coming from? Why does it need it and why didn't VS2008 put it in there if it needed it?

This seems to be a common problem with deploying addins. It like it doesn't compile that? I tried the SGEN with no luck. The problem is because I'm using a web service. ANyone else have a idea?

Hi everyone.

I've got a listBox and a list of elements in it.
I've got another windows form, and it will be created after an item in the listBox is double clicked.

What I'm asking is;

I want to "read" the name of the element from the list box, and then fill the new form according to this information.

How can I pass the listBox1's selected Item's text to the new form?

can anybody help?
