Dear experts,
I have the following problem.
I want to merge 2 xml-files into one automatically.
How can this be accomplished in the best way.
a) by a c#-pgrogram
b) by xslt-transformation
c)...
do you have any link/solution?
Kind regards
|

|
|
guess it depends on how the merge should work.
if you only need to append one file to another, cmd.exe will do the job.
xslt is fine, but you'll need something that starts the transformation process automatically.

Use the Systemm.IO.FileInfo class.

Hi,
I have a dictionary of items. I want to create a new Dictionary by taking items from it where each item meets a particular criterion. I figure that the ToDictionary extension method would suit my purpose, but for the life of me I cannot get it to compile.
<pre>
Dictionary<int, string> test = new Dictionary<int, string>{
{1 ,"a"},{2, "b"},{3 ,"c"},{4, "d"}
};
Dictionary<int, string> d = test.ToDictionary<int, string>(o => o.Value.CompareTo("d") == -1);
// compiler error on this line
//'System.Collections.Generic.Dictionary<int,string>' does not contain a definition for 'ToDictionary' and the best extension method overload //'System.Linq.Enumerable.ToDictionary<TSource,TKey>(System.Collections.Generic.IEnumerable<TSource>, System.Func<TSource,TKey>)' has some //invalid arguments
</pre>
The only thing that I could manage that came close to what I need is:
<pre>
List<KeyValuePair<int, string>> t1 = test
.Where(o => o.Value.CompareTo("d") == -1)
.ToList<KeyValuePair<int, string>>();
</pre>
I reckon I'm doing something really stupid but I can't see what it is. Can anyone help me out?
Thanks very much,

This will work for you:
IDictionary<int,string> d = (
from t in test
where t.Value.CompareTo("d") == -1
select t).
ToDictionary(item => item.Key, item => item.Value);

Does it mean you want to read excel sheet and display data in your App or you want to export the data to some other destintaion?

You can simply use ODBC to read data from excel to datatable.

Hi all.
Is exists way to binding cutsom type value to Control through databinding
Example
public class CLASSIFIED
{
public CLASSIFIED(double Val)
{
this._value = Val;
}
private double _value;
public static implicit operator CLASSIFIED(double Val)
{
return new CLASSIFIED(Val);
}
public static implicit operator double(CLASSIFIED CLASSIFIED)
{
return CLASSIFIED._value;
}
}
class SourceProvider
{
CLASSIFIED Index {get{...} set{...}}
}
...
control.DataBindings.Add("EditValue", _sourceProvider, "Index");
...
I know what i can do it through IFormatProvider interface like what : control.DataBindings.Add("EditValue", _sourceProvider, "Index", null, null, _myFormatProvider);
But what about other way, derive my custom type from AN INTERFACE what DataBindings.Add(...) recognize and format my custom type value automaticaly????
<br />
public class CLASSIFIED : ISomeInterfceWhatDataBindingRecoginze<br />
{<br />
....<br />
}<br />
}<br />
THANK!!!

How do I initiate a queue of paired values?

Dictionary dictionary = new Dictionary();
or
KeyValuePair<string,string> myKVP = new KeyValuePair<string,string>();

Did you try Queue<KeyValuePair<string, string>> ?

Hi,
I'm a newbie in C#. I want to create a C# dll exporting some functions to be used from a thirdy party application. This application can call functions exported froma DLL but those functions have to be declared as __stdcall.
Is there a simple way to export functions froma C# dll as __stdcall (or in a way it works as __stdcall) ?
Thanks
|

Hi!
No, there is no way to export a __stdcall function from a C# assembly, because of several reasons. One of the reasons is that you can't have "functions" outside a class in C#, another one is that all C# methods rely on the CLR interpreting them.
You have to create a C++ DLL to do this.
Fortunately, you can quite easily access your C# classes from a mixed mode C++ DLL, so it should be possible to create some kind of wrapper to expose a call to a method written in C# for an unmanaged callee.

The method of a wrapper c++ class was the first one I've thought and probably will be the final choice.
Anothre question ...
If a c# class method is declared as static, is it possible to export it in some way ?+
Thanks for your time
