Thank you!!!

You're not likely to get too much help with a post like that. Firstly, your title is meaningless because everyone who posts here wants help. The title is supposed to summarise the topic of the post. Secondly, you've posted far too much code. You should be posting ONLY the relevant code. Finally, you haven't provided any explanation of the problem. Just posting loads of code and saying "please fix it" is not going to cut it. You need to isolate the issue, explain what you expect and what actually happens and then post the relevant code as well as any error messages or the like.

You're not likely to get too much help with a post like that. Firstly, your title is meaningless because everyone who posts here wants help. The title is supposed to summarise the topic of the post. Secondly, you've posted far too much code. You should be posting ONLY the relevant code. Finally, you haven't provided any explanation of the problem. Just posting loads of code and saying "please fix it" is not going to cut it. You need to isolate the issue, explain what you expect and what actually happens and then post the relevant code as well as any error messages or the like.

hey, i am really sorry, i was so confused writing this thread other day, i tried so hard to fix, still same error.

the erro is here:

[COLOR=#333333]this.comboBox1.Items.Clear();[/COLOR]      
foreach (Process process in this.processlist)
      {
        if (((!string.IsNullOrEmpty(process.MainWindowTitle) ? 1 : 0) & (process.ProcessName.Contains("Tibia") ? 1 : (process.ProcessName.Contains("Hexera") ? 1 : 0))) != 0)
          this.comboBox1.Items.Add((object) new ComboboxItem()
          {
            Text = ((string) (object) process.Id + (object) ": " + process.MainWindowTitle),
            Value = (object) process.Id [COLOR=#333333]          });[/COLOR]

still same error.

But you didn't tell us what the error message was in the first place, so knowing that it hasn't changed doesn't help us all that much.

I can tell you that all those ternary operators returning 1 or 0 and then testing for 0 at the end is horrendous. It starts out with Boolean expressions so it should just stick with Boolean expressions and test for true or false. That `if` statement should just be something like:

if (!string.IsNullOrEmpty(process.MainWindowTitle) && (process.ProcessName.Contains("Tibia") || process.ProcessName.Contains("Hexera")))

When I debug the project I get error here:

this.comboBox1.Items.Add((object)new ComboboxItem()          {
            Text = ((string) (object) process.Id + (object) ": " + process.MainWindowTitle),
            Value = (object) process.Id
          });

And can't load the designer due to this error:

If you refuse to provide us with the actual error message then I'm afraid then I can't help any further.

look, when i debug the project the software appears in blank and yellow on

this.comboBox1.Items.Add((object)new ComboboxItem() {
Text = ((string) (object) process.Id + (object) ": " + process.MainWindowTitle),
Value = (object) process.Id
});
Look on this print screen below:


im trying to be 100% clear, im sorry if you arent understanding me :|

Right, so the error message in that case is "Unable to cast object of type 'System.Int32' to type 'System.String'." That tells you - and us - what actually went wrong so we know what we're actually looking for. Without that, we've got to consider absolutely everything that might ever be wrong with the code. Now we know to look for an Int32 value that you're trying to use as a String. In that specific case, `process.Id` is an Int32 so casting it as type `string` doesn't make sense. An object actually has to be that type in order to cast it as that type. Casting doesn't change the type of the data. In fact, that whole use of String.Format doesn't make sense. If you're going to use String.Format then it should be:

Text = String.Format("{0}: {1}", process.Id, process.MainWindowTitle),

Perfect!! It worked! Thank you so much!
