Good idea. There will also be a BitmapButton in the GUI Library.

To make it more precise, it enables version 6.0 of the common controls library. This version is themes aware so it will make use any XP themes enabled on the end system.

That is a bug in .NET WinForms, I can't remember if it was fixed in 1.1 or not though. This article, http://www.codeproject.com/cs/miscctrl/themedtabpage.asp[^]
describes the fix for it.

I can't believe there isn't a BitmapButton control on CP

The CP UGLY Project should look at current controls(MFC) available in CP and convert them to .NET controls.

Few weeks back I was looking for same control and I was surprised by no BitmapButton control at CP. Thought of developing my own but I own VS.NET 2002 standard version.(which is missing lot of wizards) So I gave up the idea.

After googling for sometime I found this company which has some good controls and they are inexpensive too. But no BitmapButton control yet.

File downloading - web service

I am trying to build a web service that downloads a file to my local directory.

I have the basics here but I just cannot get it to work, anybody know of any examples on this. Here is my code so far.

<code>
Dim l_oWR As WebRequest
Dim l_oWebResp As WebResponse
Dim l_oBR As BinaryReader
Dim l_oBW As BinaryWriter
Dim l_oStream As Stream
Dim bFile() As Byte
Dim l_iCnt As Long
Dim l_dtNow As DateTime = DateTime.Now
Dim l_sDir As String = l_dtNow.ToString("MMddyyyy")
Dim l_oDir As Directory
Dim l_sFile As String
Dim l_sCnnStr As String

Try

'download file
l_oWR = HttpWebRequest.Create("http://www.abc.com/abc.exe")
l_oWebResp = l_oWR.GetResponse()
l_oBR = New BinaryReader(l_oWebResp.GetResponseStream(), Encoding.ASCII)
l_iCnt = l_oWebResp.ContentLength
bFile = l_oBR.ReadBytes(CType(l_iCnt, Integer))
If Not System.IO.Directory.Exists("C:\ofac") Then
System.IO.Directory.CreateDirectory("C:\ofac")
End If
l_oStream = New FileStream("C:\ofac\t11sdall.exe", FileMode.Create, FileAccess.Write)
l_oBW = New BinaryWriter(l_oStream)
l_oBW.Write(bFile)
</code>

Thanks for any help here!

File I/O fun with binary files

As a newbie C# project, I'm trying to read a file consisting of phonelog data that was generated by my PBX and format it to be easy to do reporting. It's a binary file with each record separated by a null character (hex 00), and each record is 80 bytes long. I'd appreciate a little nudge in the right direction to get me started. The code below will let me look at the integer representation of each character, but what I really want to do is read each record in until end of file.

StreamReader re = File.OpenText("C:\\smdrdata.rec");
int input;
int count = 0;
while ((input = re.Read()) != 0)
{
//do something
}
re.Close();

Here's an example of the file data, sort of. I don't know how to show the nulls. I can email the actual file if anyone is kind enough to help.

I guess this question must be too stupid or obvious to elicit a reply. Can anyone suggest a newbie message board that might be more appropriate?

One more thing, the file is prefilled with nulls so I can't just read till EOF.

Accessing an inbox in the SMTP service

Johan Danforth2-Jul-03 5:11

2-Jul-03 5:11

Several years ago, I wrote a service in VB6 on Windows NT 4 that used the local Microsoft SMTP to send and receive mail messages between two applications.

For that I used the "CDO for NTS 1.2" COM library, which has been replaced by newer CDO (CDOSYS, CDOEX etc.) components.

Has anyone tried to send mail to the local SMTP Service and read the mail messages in the drop directory from a C# (or other .NET) program? I cannot find any methods in the newer CDO COM components go "log into" the local SMTP service as I could in the old CDO for NTS component.

I know I can send mail through the local SMTP service with the .NET SmtpMail class, and I guess I could listen for incoming *.eml files in the SMTP Drop directory and parse that mail myself, but if there's a proper way to do it I'd like to know Smile | :)

Thanks for any help guys.

I may be professing my own ignorance..but you could always write a POP3 Mail client. RFC 1939 should help ya out with knowing what to do..it may be alot easier and proper to do this, versus some hack that would monitor a directory..

Yes, yes, I know I could do that. But that would require a pop3 server, which I don't want to install or use. The Microsoft SMTP Service doesn't support pop3 as far as I know.

Problem with DllImport

Iam trying to get the pixel of a area in a screen of my program (for collison detection) the API call (GetPixel) seems to work..and it returns a int that i use with Color.FromArgb(int) (i think thats it) anyways when i try to convert the int i get back the color but...it doesnt convert correctly.....the A(alpha) of the color is always 0. Is there something i need to do before i try to convert the int ? Here is the code i use.

<br />
[DllImport("Gdi32.dll")]<br />
private static extern int GetPixel(IntPtr Handler,int x,int y);<br />
[DllImport("user32.dll")]<br />
private static extern IntPtr GetDesktopWindow();<br />
		//<br />
[DllImport("user32.dll")]<br />
private static extern IntPtr GetWindowDC(int Pointer);<br />
[DllImport("user32.dll")]<br />
private static extern IntPtr ReleaseDC(IntPtr hWnd,IntPtr hdc);<br />
<br />
//Use a method Called check pixel (overloads Int X, Int Y)<br />
<br />
int j = CheckPixel(100,100);<br />
int jm =Convert.ToInt32(j);<br />
Color c = Color.FromArgb(jm);<br />
MessageBox.Show(c.ToString());<br />
<br />
//method CheckPixel<br />
<br />
private int CheckPixel(int x,int y)<br />
{<br />
	IntPtr DC = GetWindowDC(GetDesktopWindow().ToInt32());<br />
	int jm = GetPixel(DC,x,y);<br />
	//<br />
	//<br />
	ReleaseDC(GetDesktopWindow(),DC);<br />
	//<br />
	return jm;<br />
}<br />
<br />

Quote from MSDN:

"GetPixel:
The GetPixel function retrieves the red, green, blue (RGB) color value of the pixel at the specified coordinates. "

This seems to imply that the Alpha value is undefined when returned from GetPixel. It seems as though the Alpha is always zero, but then the docs don't say that so you can't trust it.

I haven't been able to locate how to get the alpha value though Frown | :(

If I am understanding what you are asking you need to have FrontPage extensions and ASP.NET installed on the remote machine. However I don't know how firewalling works through this.
