My software (C# Winform) need to connect to a website to download a file.
The file is sought on the website with the login and password, then given to the client to download.
If I try with the browser, the website gimme a page with the password and the login and a "Connect" button.
I would like to emulate that work, without using the browser.
I'v no problem to connect to the Url and to download, but don't know how to send the login and passwor. I've try the code below, but it doesn't work.
<br />
MyLogin = "Me"; <br />
MyPassword = "11111111"; <br />
MyUrl = "http://mySite.com/MyPage.php"; <br />
clsDownLoadFile MyDownload = new clsDownLoadFile(); <br />
clsDownLoadFile.htmlStream MyStream = new clsDownLoadFile.htmlStream(); <br />
MyStream = (MyDownload.FindUrl (MyUrl, MyLogin, MyPassword)); <br />
if (MyStream != null) <br />
{ <br />
if (MyDownload.IsWebConnected()) <br />
{ <br />
string s = "login="+MyLogin+"+passwd="+MyPassword; <br />
WebClient myWebClient = new WebClient(); <br />
Stream postStream = myWebClient.OpenWrite(MyUrl,"POST"); <br />
postStream.Write(postArray,0,postArray.Length); <br />
postStream.Close(); <br />
try <br />
{ <br />
myWebClient.DownloadFile(@"C:\Temp", "MyFile.zip"); <br />
} <br />
} <br />
} <br />
I catch an exception when trying to download. I thought beacuse the Identification on the server doen't accept me.
Could someone help me, I drown...

Hello,
I have a progress bar and i have the min set to 1 and the max set to 100. I want to be able to click on part of the progress bar and for the progress bar to go to the value that l click on in the progress bar.
For example if the progress is on 10, and l click on the bar in the area of about 80, then the progress will go up to that value of 80.
Many thanks in advance,
Steve

 Weird usage of a progress bar... but you can handle the mouse down and check where the click occured. Based on the location and the size of the progress bar you can determine the value to set.

You'd have to handle the MouseDown event of the Progress control. In there, you would get the mouse coordinates where where the user clicked the mouse button. Call the control's PointToClient method with those mouse coordinates to get the point mapped to a usable point in the control. You then have to do some math to determine how far from the left side of the control the user clicked the mouse, then map that number to a value between 1 and 100 so you can set the appropriate value in the ProgressBar's Value property.

Why not use a TrackBar instead?

Process.Start appears to only be able to start a process on the same machine.
Is there a way to start a process or preferably a php program on a remote machine.
What I want is to call a php on the server from a C# program on a workstation.

Alf Stockton

True. Otherwise this is a HUGE security risk.

You would need to use WMI and the System.Management namespace to launch a remote executable. You'd also need to provide credentials to an account that has administrator rights to the target machine.
Win32_Process[^] WMI class, Create method.

 i just want to know if i make an applet i mean like java applet and integrate it with html or php to a web page (not using asp.net) now for any client using that applet must have .NET frame work installed but does the server must also have .NET framework installed. i think U understand my question :s

Yes, your client must have the .NET Framework installed for it to run. If your server is going to be executing managed (C#, VB.NET, Managed C++, ASP.NET) code server-side, then the server has to have the .NET Framework installed also.

In addition to what Dave said, keep in mind that you can only do limited things when running an "applet"; i.e. you can't delete files on the client system, or access the registry, and so on. Doing so will result in a SecurityException. Look up Code Access Security in your favorite search engine to learn more.

Hi,
I am having various controls say... Estimated Start Date, Estimated End Date(both are text fields with date)
How can I perform these validations using Asp.net Validation Controls
1) If I input Estimated End Date, it is compulsory for me to input Estimated Start Date, other wise it can be left empty.
2) Estimated Start Date >= Todays date (if i input it)
Please Help me..
Thanks

sorry 4 misunderstanding.
I need to convert the picture on the panel to bytes.
I did that but it works only for the backgroungimage of a panel.
in my program I use 3ds max to draw on the panel
I need to convert the picture on the panel to bytes
thx 4 replying

this is the function I use to get the bytes of the backgroungimage of the panel
private void fun()
{
pna1.BackgroundImage.Save("m"); //m is the name of the file
bm = new Bitmap("m");
//the size of the panel is 240*160
byte [,] matrix= new byte [240,160];
byte red=0, green=0, blue=0;
byte [] test=new byte [1];
for (int y=0; y < 160; y++)
{
for (int x =0; x < 240; x++)
{
Color u=bm.GetPixel (x ,y);
//I need only one byte represent each pixel
blue = (byte)(u.B/64*64);
green = (byte)(u.G/32*8);
red =(byte)(u.R/32);
matrix[x,y]=(byte)(red + green + blue);
}
}
}
