You could easily do this in a RegEx by itself and avoid looping through the matches. \W captures all non-word characters (anything not a-z A-Z or 0-9), so you can then just use the Replace method of the Regex class.

Dim resultString As String
resultString = System.Text.RegularExpressions.Regex.Replace("ABC$%123*>890!#XYZ", "\W", " ")

I haven't done VB since VB6, but I assume that should work as it's a simple statement.

Hi,

I need to write an Windows Application where the user authenticate against a SQL 2005 Server. What I need is to have a custom authentication and authorization system that's available when building ASP.NET apps.
How would I go about finding out how to type in a Username and Password and then authenticate against a SQL server.

Thank you

Hi all,

im working on a Solution to grab all Files in a Directory, but the Compiler woudn't accept my Code. He says all the Time (string have no definition for "GetFiles"

Here is my Code

private void Form3_Load(object sender, EventArgs e)
{
string dir = @Application.StartupPath + "\\XML\\";
DirectoryInfo tdir = new DirectoryInfo(dir);
FileInfo[] dateien = dir.GetFiles(); //<-- Here the Compiler underline GetFiles as a Mistake, why
}
Why he do that?
Thanks for helping
Daniel

Hi, if file name (string[]) list is enough for you, you could use Directory.GetFiles(dir) static method too. (That's what I usually use, dunno why your code shows error.)

Oh, your code should say "tdir.GetFiles()" I think Smile | :)

it sits right in front of you, there is dir and there is tdir, they ar not the same.

if you want to program, you should be able to spot a mistake in the line the
compiler tells you is wrong; rest assured, the compiler will be right almost
all the time, and way more often than you are.

Thank you alot, Ferenc Veres, it was that, what you said, the code should say tdir instead of dir.

if you want to program, you should be able to spot a mistake in the line the
compiler tells you is wrong; rest assured, the compiler will be right almost
all the time, and way more often than you are.

I know that i should be able to analyse and interpret compiler mistakes, and i even dont know, why i put dir before getfiles()
Maybe it wasnt my day yesterday, ... anyway thank you for your help and maybe next time i can help you Smile | :)

They hide those in the documentation. Good luck, you're going to need it.

Reference Implementations are executable sample applications that demonstrate patterns & practices guidance in action.

You can use Graphics.FillRectangle with a width and height of 1.

Standards are great! Everybody should have one!

why are you going to FillRectangle that is use for draw rectangle.
C++ and VC++ have set pixel.

There is in fact a SetPixel method.

Well, you didn't say that you needed it on the graphics object. You spoke of image processing, there's no way you can do image processing without a bitmap, so I assumed you were working with a bitmap. A 1x1 rect or a line that is one pixel in size, are your best bets then, I guess.

Hi,

If you are looking to set the Column caption of DataGridView to "ABC" and "BCD" after binding it to DataSource (DS) then you can do it in the following manner:

BEGIN CODE
this.dataGridView1.DataSource = ds;
this.dataGridView1.DataMember = "test";

this.dataGridView1.Columns[0].HeaderText = "ABC";
this.dataGridView1.Columns[1].HeaderText = "BCD";

END CODE

I hope this helps Smile | :)

Still won't do.
when buiding, report Index foul.
before dataGridView binding data,the DataGridView don't has columns,
so report Index foul.I think to is so.
