Lol!
I don't REALLY know that the label is going to be "Attack", the database may change. I have a foreach statement that goes into the database, and sets an array(the array is where I really store the skill). I need to be able to do this:
lbl(skill).Text = skill;
But in a way that is acceptable, I don't have to do it that way either, just some way that is dynamic.

Obviously, but I followed your example, and the fact that you tried to cast a string to a label left me thinking this was what you needed to know.

You can't name your variables locally like that. You CAN set their ID and tag values in this way.
You need to create a new Label ( just look in the InitializeComponent part of an app with a label predefined to see all the stuff you need to set ), then you can set it's text, and it's id/tag properties.
Oh, is this Winforms, or ASP.NET ?

ASP.NET, that is the problem.

OK - well, you need some sort of placeholder in your page, so you know where the labels will end up. The way to add a control to an ASP.NET page is to add it to the controls collection of the item that is to be it's direct parent.
If all you're doing is showing a bunch of labels, I'd be more included to use a repeater or datagrid, and bind it to your data source. Will that not work for you ?

Here is what I have this may show you more...
StringBuilder szMyTable = new StringBuilder();
///The page begining
///Starts the html, body, form and table for the page
szMyTable.Append("");
///Establishes the number of tables, testboxes, and buttons using a FOR statement
foreach (string skill in skills)
{
szMyTable.Append("");
}
//End the page, then send the page to the Redirect
szMyTable.Append("");
szMyTable.Append("<asp:label id="lbl");
szMyTable.Append(skill);
szMyTable.Append("" runat="server" text="\"");
szMyTable.Append(skill);
szMyTable.Append("\"">");
szMyTable.Append(" |
");
Response.Write(szMyTable.ToString());
Response.End();
A datagrid will not work, as I am going to have the szMyTable include Textboxes and Buttons.

Why are you doing this in an ASP.NET app ? This is a nightmare.
ExpertComing wrote:
szMyTable.Append("szMyTable.Append(skill);
szMyTable.Append(" runat=server Text=\"");
You can't do this, you're generating HTML *after* the controls have been created.

You're treating asp.net as if it was asp. Scrap all this code, it's really working against the framwork. Instead, create a datagrid, which CAN include textboxes and buttons. There's a bit of work in getting the events from dynamically created controls, but it can be done, and that way, you'll use the framework instead of fighting it.

What is the difference between asp and asp.net?
Both active server pages right?
|
|
|
|

No, asp is the old framework, it uses VBSCript and JScript. In ASP, you have to build your result sets using the sort of code you're using. ASP.NET is the framework that gives you access to things like codebehind, code reuse, etc. It's a whole different world. There's not enough money in the world for me to ever take an asp project again.

But they are both actice server pages, but ASPX is the more efficient one correct?
|
|

They are both an ISAPI filter at the end of the day. Look, ANY framework generates HTML, but that doesn't mean you can do anything you want just writing your own HTML. ASP.NET is named as it is to show that it's the successor of asp. Have you ever used asp ? If you haven't, then I have no idea why you're generating code as you are ( especially putting in body and form tags ), but I promise you, it's the difference between cutting down the tallest tree in the forest with a chainsaw, or with a wet herring.

No, I myself, have never used asp, although my dad works for Microsoft, and he taught me how to code, he did it that way, so I do. I have never used a datagrid before, can you give me a quick lesson or article to help me out.
Thanks a ton man, you have help me threw some problems before, thanks for all your help.

I have the following c++ declaration
static FT_STATUS FT_ListDevicesEx(String *DevicesList);
{
DevicesList = "Hello";
}
Inside this function I modify the DeviceList string, but when I return to my c# code the string is not changed.
in c# i use the following code to pass the string.
string a = "12345";
FTDI.FT_ListDevicesEx(a);
When I arrive in ListDevicesEx the DevicesList string is 12345, then is modified in Hello, but at return in c# a = 12345 again!
What is the solution ?
Best regards.

You need to use the "ref" keyword from C#. Also, make sure that the "ref"-style usage is declared for the C++ function as well (if it isn't already set that way).

Have you tried [^;\s]+?

What about this?
(?>\w|\d||\B)[^;\s]+
Btw, if you want to strip all string with an ; or \s between each other, why not use the String.Split() function?

hi,
<br />
input "Gerald 123; Franz!'§§"<br />
<br />
regex: Regex regex = new Regex(@"(?>\w|\d|\B)[^;\s]+");<br />
<br />
output:<br />
array[0] = "Gerald";<br />
array[1] = "123";<br />
array[2] = "Franz!'§§";<br />
<br />
but i want have: array[1] = "Gerald 123";<br />
array[2] = "Franz!'§§";<br />
<br />
i know its better to use the split function
but i want to run that with regex...but it's not possible?

Do you actually want to split the spaces or the semicolons?

hi,
the regex should work like that:
<br />
char[] separators = new char[] {';'}; <br />
foreach (string sub in textBox_Receivers.Text.Split(separators))<br />
{<br />
string str = sub.Substring(0, sub.Length);<br />
if(str.StartsWith(" ")) <br />
{<br />
str = str.Remove(0,1); <br />
}<br />
<br />
Receivers.Add(str);<br />
} <br />

\s?([^;]+)
This one works fine for me

hi,
yeah thats fine:
<br />
MatchCollection matchCollectionReceivers;<br />
Regex regex = new Regex(@"\s?([^;]+)"); <------- whats the '?' here? = AND?<br />
matchCollectionReceivers = regex.Matches(textBox_Receivers.Text);<br />
<br />
foreach (Match m in matchCollectionReceivers) <br />
{ <br />
string str = m.Value;<br />
if(str.StartsWith(" "))<br />
{<br />
str = str.Remove(0,1);<br />
}<br />
<br />
Receivers.Add(str);<br />
}<br />
advantage: less code lines than the .split() version
cu+thx

No, the ? means that the space is optional.
But your code is wrong - I put brackets around the [^;]+ so that the results will be stored in a GroupCollection. This way you don't need to check for any leading spaces anymore.

Regex r = new Regex(@"\s?([^;]+)");

Console.WriteLine(mc.Groups[1].ToString());
