That's it, but it's not very elegant. You can use properties to return the value of visual objects. Like so. There is no reason to create that form and leave it in memory. It better to use it and then destroy it as soon as you're done.
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
using (Form2 f2 = new Form2())
{
f2.ShowDialog();
label1.Text = f2.TextValue;
}
}
}
public partial class Form2 : Form
{
public string TextValue
{
get { return textBox1.Text; }
set { textBox1.Text = value; }
}
public string LabelValue
{
get { return label1.Text; }
set { label1.Text = value; }
}
public Form2()
{
InitializeComponent();
}
}

There's actually an article here that shows how. Take a look here:
[Passing Data Between Forms]
If that doesn't work try using searching Google for something like: "Passing data between forms in C#"
Good luck.

Well, there are several ways.
Simple way is to make property to Form1 class which set values to textbox so when button clicked, you have to set to Form1.XXX Property(You have to get Form1 class instance from From2 class) .
Other way is to use message.
You think more depthly, there are many ways.

I have managed to create 2007 excel by Open XML SDK 2.5 in c#. Is there any way I can create 97-2003 excel as well? It looks like Open XML doesn't support older version than 2007 office. I've been googling but couldn't find out how.

Yes. And I need to generate .xls file automatically (using Windows Service). There is this NPOI - the .NET version of POI Java project which can create .xls file https://npoi.codeplex.com/[^]
Any idea if this works with user interface free applications (e.g. services)?

Hello,
How can I obtain the value from a specific node in my XML file?
For example please consider the xml structure below. How would I for instance obtain "max" and "min" values for node
<xx atty="3" attz="0"> and in case it requires a different search method I would also like to know how to obtain the value at node
<vars var0="3" var1="0">0</vars>
?
Anxious to learn how to do this
Best Regards
Tom
="1.0"="utf-8"
<data device="xx" version="1">
<node1>
<xx atty="2" attz="3">
<max>0</max>

<xx atty="3" attz="0">
<max>0</max>
<min>0</min>

LINQ is your friend when walking XML files.
There are a lot of examples using Linq queries over XML to get data out of the file. I'm too lazy right now to Google it or search here on CP so I'll leave that to you. But that should get you what you want.

How about this: //xx[@atty='3' and @attz='0']/*[name()='min' or name()='max']

Hey bimbambumbum,
that's my way of doing it, with this code you'll get the attributes to your specific node. Code is written for .Net Framework 3.5
Additionaly i posted the XML file so you can backtrace the work and derive your code from it.
All you need to have set up is
the xmlDoc and a xPathNavigator xmlNavi = xmlDoc.createNavi...
public DataTable LoadValueConfig(string ControlName, string ParentName, string FormName)
{
DataTable _dt = new DataTable();
_dt.Columns.Add("Name");
_dt.Columns.Add("Value");
_xmlNavi.MoveToRoot();
_xmlNavi.MoveTo(_xmlNavi.SelectSingleNode("WindowConfig"));
if (FormName != "") { _xmlNavi.MoveTo(_xmlNavi.SelectSingleNode(FormName)); }
_xmlNavi.MoveTo(_xmlNavi.SelectSingleNode(ParentName));
if (_xmlNavi.MoveTo(_xmlNavi.SelectSingleNode(ControlName)))
{
_xmlNavi.MoveTo(_xmlNavi.SelectSingleNode(ControlName));
_xmlNavi.MoveToFirstAttribute();
do
{
if (_xmlNavi.Value != "")
{
_dt.Rows.Add(_xmlNavi.Name, _xmlNavi.Value);
}
} while(_xmlNavi.MoveToNextAttribute());
}
return _dt;
}
XML File:
<WindowConfig>
<kopiefrmHauptfenster Position="460:21" Size="878:1170" WindowState="Normal">
<checkBoxItem1 chBoxCheck="True" />
<bsAdminTest Active="False">
<switchButton1 switch="False" />
<richTextBoxEx1 Text="" />
</bsAdminTest>
<Project Active="True">
<navigationPane1 CheckedButton="Projekte" Expanded="True" />
<expandablePanel1 Expanded="True" />
</Project>
</kopiefrmHauptfenster>
</WindowConfig>
Edit: added the comments for more Explanation
Ist probably not the best and most comfortable solution but int works for me, optimizations appreciated
if(this.signature != "")
{
MessageBox.Show("This is my signature: " + Environment.NewLine + signature);
}
else
{
MessageBox.Show("404-Signature not found");
}

Is It Possible that we store a field of a table from a database and store it in static variable..
Plzzzz Help Me out this..
further I want to use that variable in if-else condition,
for example:
if (datafield(Gender)="male")
open maleForm
else
Open FemaleForm..

The simple answer is yes you can. Static does not mean you cannot change the value of the variable.
Your idea of using the variable in the if statement is correct.

But Sir I failed to do it.
My Detailed Problem is:
I have two forms (Male and Female).
and I have a data base in which there is a field(Gender)
i want to extract the value of the gender field i-e male or female in a variable TEMP
is this possible that I use TEMP in if-else condition As Below??
if(TEMP=="Male")
{
Messagebox.show("Hello Mister");
}
else
{
Messagebox.show("Hello Miss");
}
If Possible then plz give me the exhact code..

Sorry I get paid to write code, the only thing I can suggest is you get a book and work through the examples or find some tutorials. You do not have enough knowledge to understand the answers you are getting.
When searching for tutorials you should specify your database and what platform you are intending to use Winforms/ASP/WPF etc.

As Mycroft has said, yes you can.
However, you probably don't want to, unless you have only one person or gender in your database.
If you make it static, you only get one per application, which makes it impossible to expand things later to support motte than one record at a time. Normally, this kind of information would be stored as part of a class instance identifying a person, rather than as a static variable.
Under normal circumstances, it is evidence of poor design to have to use static variables for something like this, and will generally cause you significant problems later.

Sorry Mr.OriginalGriff but I dont understand.
Can U plzz elaborate it??
With Practical or coding??

Not really, because the problem seems to be a bit more fundamental than you think - I'm not at all sure you have understood the basics of OOPs design (and without that, nothing I write is going to be understandable)
Plus, from the tiny amount of code you provide, I just don't have enough context to write anythign that woudl be useful to you.
How about you go back a couple of stages and explain what you are trying to do? Not just the brief bit you have described in your question, but an overview of the whole project and how you are planning on implementing it? (not too much detail, a good paragraph should do)

As others have already pointed out, that is not the way to do it. You need to process this decision for each database record so it would be completely wrong to store that value in a variable, static or otherwise. The code you have shown above is correct, where datafield(Gender) is a field in the current database record.

Yes, you can do it. Static keyword means, you can not change value but refer it.

Hello-
I'm fairly new to C# (classic ASP guy), and I'm having a heckuva time with this. I am hoping someone can point out my flawed logic and/or syntax.
I first need to ascertain if the current article group is one of several that need to be treated differently. If it is, it defines the var "strbody" using a complete value as retrieved from the database. If it is not one of those special article groups, then I have to do some string manipulation to format the retrieved value before defining and displaying it.
My string manipulation code is flawless, but neither of the strbody vars I define in my if/then/else block is recognized when I call it below the code block???
@{
string group = Model.ArticleGroupName;
if (group.Contains("Spacial Orientation")||group.Contains("Topography")||group.Contains("Osteology")||group.Contains("Angiology")||group.Contains("Neurology")||group.Contains("Myology")||group.Contains("Radiology")||group.Contains("Misc. Drawings")||group.Contains("Clinical Testing"))
{
var strbody = item.ShortBody;
}
else
{
string s = item.ShortBody;
string sLess = s.Remove(0, 12);
int index = sLess.IndexOf("Summary");
var strbody = (sLess.Substring(index + 8));
}
}
@strbody
That code results in the following error:
\Plugins\FoxNetSoft.Articles\Views\ArticleRead\List.cshtml(76): error CS0103: The name 'strbody' does not exist in the current context
I am new to this, so please don't hesitate to chastise me for doing dumb stuff...I need to learn!
Thanks,
Steve

Declare strbody outside of the if/else block, then assign it inside the block. As your code stands, the scope of the variable belongs inside the relevant if/else part. This is just standard behaviour for C#; it's the reason you have to define it twice in the if/else block right now - they are actually different variables. The fact that you can use the same name here is irrelevant.
