hi Christian Graus,
Thanks for your help. I will do a checking first before call a delegate.

Great - that will stop the crash, but unless you hook up the right instance, it's still not going to work

While I am performing calculations my debug answers are showing up like 0x00000096.
Can I set a propery to display the actual numbers.
Can someone help?
Thanks.

I found out that when you highlight the variable and right click you get a menu. At the bottom of the menu you can check Hexadecimal display.
Thanks everyone.

I have a C# app which I have behaving like an IM client; when the user selects the Windows Close button I hide the form and simply exist thru a System Tray icon. Since I'm not actually 'closing' the app, I'd like to replace the 'Close' hover text with something more appropriate like 'Hide'.
Is this possible?
Thanks
John

Hello all.
I have a c# solution that has 4 different projects, each project has an app.config file. I am able to change the Connectionstrings section for my startup project but not for the other projects and I need to do that.
But the problem I think is that the other projects are DLL so there's no config file for them in the BIN folder and NullReference exception is thrown.
But I need to change the connectionstring at runtime
How can I achieve that?
I already tried sending the parms like this:
ModifyCnnStr("N1.Properties.Settings.DBConnection", "new cnnstr");
ModifyCnnStr("N2.Properties.Settings.DBConnection", "new cnnstr");
ModifyCnnStr("N3.Properties.Settings.DBConnection", "new cnnstr");
but it doesn't work.
This is the function i have:
namespace N1
public static class CryptConfig
{
public static bool ModifyCnnStr(string settingName, string newCnnStr)
{
try
{
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
config.ConnectionStrings.ConnectionStrings[settingName].ConnectionString = newCnnStr;
config.Save(ConfigurationSaveMode.Full, true);
ConfigurationManager.RefreshSection("connectionStrings");
return true;
}
catch (Exception ex)
{
System.Windows.Forms.MessageBox.Show(ex.ToString());
return false;
}
}
}
}
I also tried having this class in each project but still wouldn't work. I need to use the config's connectionString because I already have lots of datasets using the connectionString.
Help please
Thanks

Your loop is writing each line to console, then writing the last line to your StreamWriter. Without a better description of the problem, I'd say initialize your StreamWriter before the loop and write to it instead of the Console.
Then again, I can't tell for sure what you're actually trying to do.

In the future, you can use "\r\n" instead of just "\n".

I´m making a C# spelling test.
I´m having trouble with the grading process.
My idea is not having a spell check but rather compare two texts and count the errors. One text is hidden of course.
How would you think the easiest way to do this would be?
|
|
|
|
|
Out of curiosity, how will the user know what words she is supposed to spell for the test?
|
|
|
|
|
LMAO
Spelling Test, enter the correct spelling for the following words:
1) hyperbole
led mike
|
|
|
|
|
Oh, I forgot to mention. A mp3 file will be played where the text is read out.
But do you have any ideas on what the easiest way to do this would be?
|
|
|
|
|
Use character arrays for the strings and check each character. You need to decide if you give points for a correct word with different length and handle that scenario.
correct answer: hyperbole
user enetered: hyperboole
The lengths are different so a straight char comparison won't work. You should probably search the rest of the entered text for the char.
Good luck as there's plenty of ways you can give points.
|
|
|
|
|
why would you do a char by char comparison instead of just comparing the strings?
I misunderstood... I didn't realize this was more than a "right" or "wrong" problem...
<br />
if (string.Equals(sUserAnswer, sCorrectAnswer, StringComparison.OrdinalIgnoreCase))<br />
{<br />
}<br />
else<br />
{<br />
}<br />
I suggest that you create an XML file that specifies the word to spell along with the location of the media file that corresponds to the spoken word. Something like:
<words>
<word media="C:\Words\Hello.mp3">Hello</word>
<word media="C:\Words\Hyperbole.mp3">Hyperbole</word>
...
</words>
The application should then allow you to load the XML file that corresponds to the test you want to take.

My idea was to have a test where the student or who ever is taking the test, would listen to a mp3 file. I was thinking about having the mp3 played on an external player.
It is a block of text, so I´m thinking is it possible to compare two sentences?
Could any of you guys show me some example of how this is done?

Of course it's possible to compare two sentences. A sentence is just a string, right? But how will comparing sentences solve your problem? The user will be spelling words, not sentences, right? Don't start solving the wrong problem!
I think you need to take a step back and think about what you're trying to do. Spend some time with paper and pencil and sketch out some use-cases. This will help you conceptualize the problem. For example, what do you want the user experience to be? Pretend that you are going to take a spelling test. How would you expect the application to behave? Once you jot down the basic use case, start considering edge cases. For example, what if I decide to change my answer after I've already typed it in? Will the words be checked immediately after they are entered? Or will they be checked all at once when the user "finishes" the test? If the audio is not associated with the words in your program, how will you know which word the user was trying to spell? What if the user spells the words in the wrong order (the application expected them to spell "Hello" then "Hyperbole" but they spelled "Hyperbole" then "Hello")?
Going through the use cases will help you conceptualize the problem and prevent you from being short-sighted in your solution.
Good luck!

I have some use cases.
How would you do this?
|
|
|
|
|
Show me one of your use-cases and I'll be glad to help you think through this.
