Ok it sounds good enough, but I will still need to loop through it to search for characters not allowed and to remove them. Once I have removed these characters, then from what is left will I create a unique id of about 9 characaters in length.
private string m_sExcludeChars = "IO01";
If the string chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
How do I loop through it and remove the characaters that I have defined in m_sExcludeChars? So the final string should look like this after the 4 characters have been removed:
"ABCDEFGHJKLMNPQRSTUVWXYZ23456789"
O yes, if I declare a char array like:
private char[] chars;
How do I append characters to it? I want a similar result to:
private char[] chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789".ToCharArray();
I hope this makes sense.
Regards,
Brendan

Can't you just remove the unwanted characters from the original string constants?
Otherwise they can be removed with some Replace calls, or more efficiently with a regular expression:
chars = RegEx.Replace(chars, "[IO01]", "");
Do you really need a char array? You can get char values from a string in the same way as from a char array:
char myChar = chars[index];

What's wrong with that code?

After an installation for a single user all went well, but it I try the same installation for all users the shortcut on users desktop points not to my application (.exe) but starts the .msi again.
If I start my app (.exe) in the users application folder directly all works fine.
Do I have to install additional folders for a All Users desktop and all users program folder?
Thanks

I rewrote the whole setup-project: Now it works... It seems an internal error.
Then there is probably a minor bug: If I install a project as all users in the Software-install folder the icon is a yellow folder icon. If I install a project as single user the in the setup project selected icon appears.

in the VS-setup project go to the user interface and add in the End-Section a new dialog form: Readme (or something like that, I use a german version of VS there the name of this dialog is "Infodatei")
Hope this helps

Why won't the Form see this method?

// TODO: Add constructor logic here
real = 0;

You wrote Anonymous wrote:

The name 'GetNextPen' does not exist in the class or namespace 'ComplexTest2.Form1' error because the compiler will think GetNextPen() member of Form and this not true
because it is a member of complex2 and you didn't call it from an object of this class

are you replaced all places you call this function or gust this line? you need to replace all the places like
Pen p = GetNextPen(); too

hi there! 
can i know what designer class should i inherit to use it for winforms?
i used the parentcontroldesigner class, but it seems it's not applicable.. 
or a winform doesn't support designer? if ever, what should i do to make a designer verb for winforms?
tnx in advance!

You may want to take a look at the code for #Develop. If I recall correctly, they've got a WinForms designer in there. Might be worth taking a look at.
Picture a huge catholic cathedral. In it there's many people, including a gregorian monk choir. You know, those who sing beautifully. Then they start singing, in latin, as they always do: "Ad hominem..."

Why if XmlReader has an EOF property, the BinaryReader doesn't have it?
I don't like this, you can read why in my blog:
The EOF Issue[^]
How do you solve this issue?

Use the ReadBytes method.

b { font-weight: normal; }

Yes, we can use ReadBytes, then why bother to use BinaryReader!?
I like to BinaryReadar because you read primitive types.
using ReadBytes you have to write code like this:
byte[] data = f.ReadBytes(sizeof(double));
double value = BitConverter.ToDouble(data, 0);
The problem is that accroding to documentation:
==== Microsoft Documentation ====
Return Value
A byte array containing data read from the underlying stream. This might be
less than the number of bytes requested if the end of the stream is reached.
======
What happen when EOF is reached? data is null?
Also this could generate an exception to be thrown when I call BitConverter.ToDouble().
BinaryReader is bad designed.

No. You simply get an array that contains less bytes that you requested.
The way to detect end of stream is to examine the length of the array. If the length is shorter than the number of bytes requested, you have reached the end of the stream. The array will contain the last remaining bytes of the stream. If you already read all data up to the end, the length of the array will be zero.
You have to check the length of the array before you try to convert the bytes to a double. If there aren't bytes enough for a double, you have reached the end of the stream.
ediazc wrote:

I don't think so. Perhaps it's not designed the way you are used to, or maybe not designed the way you try to use it. I believe it's rather well designed for it's purpose, though.

From your blog, your first snippet of code does work, with a few modifications.
void Open()
{
FileStream stream = File.Open(@"C:\myfile.txt", FileMode.Open);
byte b;
while ((b = (byte)stream.ReadByte()) != 255)
{
Console.WriteLine(b.ToString());
}
}

Then it can't be used to read a file thas has the byte value 255 in it, as that also will be interpreted as end of file.
---
b { font-weight: normal; }
|
|
|
|
|
Oops. b must have been declared int and I shouldn't have casted ReadByte. This will work
void Open()
{
FileStream stream = File.Open(@"C:\myfile.txt", FileMode.Open);
int x;
while ((x = stream.ReadByte()) != -1)
{
byte b = (byte)x;
Console.WriteLine(b.ToString());
}
}

That particular code is not mine, is taken from microsoft documentation.
The error is from the documenter, who obviusly doesn't know how to read a stream  .
Eduardo Diaz

well.. why don't you just check if the stream position property equals to the length?
that should solve the problem.
void Open()
{
FileStream stream = File.Open(@"C:\myfile.txt", FileMode.Open);
byte b;
while (stream.Position < stream.Length)
{
(b = (byte)stream.ReadByte()) != 255
Console.WriteLine(b.ToString());
}
}
It will also work if you are using a BinaryReader.

I want my program downloads an HTML file from a site using a simple address that normaly causes my browser to redirect to a LONG complicated address showing the site im after.
But when i try to access the same page from my program using the same shortened address i download an HTML file but its just basicly a blank html file (head and body) with an error message in the body.
Rather than the page my browser redirects to.
I have tried feeding my program the LONG(actual) address and it reads the file just fine form there. But i cant depend on my program recieving the long direct address when its up and running.
So is there a way to get it to read the page it should be redirected to?
Thanks.
-- modified at 21:30 Wednesday 5th October, 2005
/EDIT: I meant to add im using request.AllowAutoRedirect=true;

|
|

Hmm it seems the redirection does work when used on other pages.... is it possible that some form of spider/bot blocking could be inplace to stop the redireciton or is it somthing as simple as me needing to learn how to enable cookies, etc?

Hi,
I am doing a project using forms. I want to create a global struct common to all forms. I want to create an array of that struct and to set the values in one form and retrieve in other forms.
How do I do it. I have created the struct but each time when I create an object for the struct the values are lost.
pls help.
