It needs converting, it doesn't just open ?

By Defult with VS Express and has an Icon of VS Express yes
but i'd just like to see it like with an VS Por Icon and So...
i know it's a bit petty

Does the reverse work? I've got Pro at work and Express at home, can I move a project freely between then providing it doesn't use any of the Pro-specific features?

am developing an windows application where i am using MSI plessey TTF font in this font i need to calculate check digit so how can i do that check digit calaculation

private string msiplessey(string abc)
{
string value = "";
string values = "";
string adds = "";
string evenvalues = "";
string evenval = "";
string evenadds = "";
string resultadd = "";
string fval = "";
long add = 0;
long abcd;
long evenadd = 0;
long result;
int checkvalue = 0;
int finalresult;
for (int i = abc.Length - 1; i > -1; i -= 2)
{
value += abc.Substring(i, 1);
}
for (int j = value.Length - 1; j >= 0; j--)
{
values += value.Substring(j, 1);
}
abcd = (Convert.ToInt64(values) * 2);
string oddvalue = abcd.ToString();
for (int k = 0; k < oddvalue.Length; k++)
{
adds = oddvalue.Substring(k, 1);
add = add + Convert.ToInt64(adds);
}
for (int l = abc.Length - 2; l > -1; l -= 2)
{
evenvalues += abc.Substring(l, 1);
}
for (int m = evenvalues.Length - 1; m >= 0; m--)
{

}
for (int n = 0; n < evenval.Length; n++)
{

evenadd = evenadd + Convert.ToInt64(evenadds);
}
result = add + evenadd;
resultadd = result.ToString();
finalresult = Convert.ToInt32(resultadd.Length);
fval = resultadd.Substring(finalresult - 1);
checkvalue = (10 - (Convert.ToInt32(fval)));
if (checkvalue == 10)
{
checkvalue = 0;
}
else
{
checkvalue = (10 - (Convert.ToInt32(fval)));
}
return checkvalue.ToString();

Hi there.
I think string and String class are equivalent.
Is it true ?
What are the different between them ?

string is a synonym for System.String

Hi Colin,
Not on topic but you may know...
Consider the declarations below:
<br />
<br />
public Delegate void Testing1();<br />
public delegate void Testing();<br />
<br />
The first declaration will not compile. I thought delegate and System.Delegate were the same things?
Cheers,
|

No its not the same thing..
"Delegate" is the baseclass that all delegates derive from.
(containing methods like DynamicInvoke etc)
The "delegate" keyword will tell the compiler that it should output a class deriving from Delegate.
(delegates are classes in IL)
So "Delegate" is more like object/Object.
While "delegate" is like the "class" keyword.
eg:
public class SomeClass : Object
public delegate void SomeDelegate () /* : Delegate */

Java's Properties class (http://java.sun.com/javase/6/docs/api/java/util/Properties.html[^]) is an easy way to serialize a bunch of properties to and from a file. I am trying to port a Java application that makes heavy use of this class, to C#. What is the easiest way to emulate this behavior?
I thought about XML serialization, but that doesn't work because all the field names have to be specified in advance. Any ideas?

How about a Hashtable. The Java properties class extends Java's implementation of a hashtable, so why not use a Hashtable in C# also?
|
|
|
|
|
Hey Colin,
That's true, it does extend hashtable - but the real value of the Properties class comes in the utilities it provides for saving/loading that hashtable's contents to streams in different formats (XML, flat file, etc.) This capability is what I am looking for. If I don't find it I'll have to write it and post it here
|
|
|
|
|
using application/ user settings in c# is at least as easy as properties in java. however, c# settings are serialized in xml, whereas properties are not.

I have a predefined user control designed at design time, and want it to load a form at runtime
it seems simple but i can't get it to work
pls help
|
|
|
|

Don't you just make an instance of the control and the add it to the form, like so:
MyCtrl control = new MyCtrl();
control.ClientSize = new Size(100,25);
control.Location = new Point(3,3);
...
myMainForm.Controls.Add(control);
My current favourite word is: I'm starting to run out of fav. words!

Yes thanks!!!
I used the same way but made an error in the namespace

I put a binary file into a table in a dataset. I then write my dataset as a XMLfile using DataSet.WriteXML
When I look at the field with my file-content I have a string wich look like this ...
"<content>/9j/4AAQSkZJRgABAgEAYABgAAD/7ABzRHVja3kAAQAEAAAAPAADAF4AAAAtA<"
What kind of string is that? How can I get it without using dataset/writexml to get it?
I have a special solution where I need to get that string.
Please hekp // henrik

How are you storing your binary file before putting in the datatable? If you store binary file in byte[] then Google for 'convert byte array to string' You can use BinaryReader class for reading binary data.

I think the DataSet uses Base64 encoding when it serializes binary fields into XML. I may be wrong, but it is the most common way to encode binary data in XML.
To read it, you could use a System.Xml.XmlReader (and its ReadElementContentAsBase64 method once you've located the correct field). However, the normal way to do it would be to recreate the dataset from the XML file, though (using ReadXml on a new dataset)...
If for some reason you don't want to use the system-provided XML tools and instead want to read the file as text and do your own decoding, you can either google for base64 or use, for example, System.Convert.FromBase64String.

Yeap ... It is base64 ...
Found the solution yesterday ...

The app I'm working on has quite a lot of collections, some of which will hold several thousand items that have numerous fields - some of which are collections themselves.
At the moment I'm leaving everything to GC automatically and it's working, but I'm concerned that it may cause problems in production on lower spec machines if GC doesn't reclaim the memory.
Would I be better implementing IDisposable? Are there any pitfalls to doing so?

Since you don't have code that access unmanaged memory, no need of implementing a dispose pattern. GC is efficient and it will take care AFAIK.
