It seems that you are not clear about what you are going to do. I will suggest you to Buy some beginners ASP.NET Books and start reading. This will help you to longer run. As you are confusing with Classes and Session/Application Variable.
Thanks !

You can use the following to create a variable name.
this.Request.Application["name"] = "This is my application";
To get the Name variable use
string s = this.Request.Application["name"].ToString();
If you are outside the page use
HttpContext.Current.Request.Application["name"]
instead.

The error means what it says. You are using virtual paths, and when you change the location, that causes them not to work, because they try to go above the root of the application.

how are you writing an ASP.NET application if you don't understand what I said ? I can't make it any simpler. The error message means what it says. You're using virtual paths, which means when you move the page location, the file path also changes.

I have a div in my master page. The contentplaceholder is inside that div. My need is to display the page without scrolling the page. If the content in my page is heavy then the page will not scroll in the sense my banner and the footer have fix but the content inside the placeholder will scroll. But my problem is when i give a particular height to the div when i enter the full screen mode the footer will shifted to almost middle of the page..
I want to place the content inside that div and i need the scrolling in both full screen and normal screen mode with my footer fixed at the bottom of the page... And i need this property browser wise... Atleast for safari,IE,mozilla,chrome..
Have any solution for this problem... I will copy my design below...
<asp:contentplaceholder id="ContentPlaceHolder1" runat="server">
|
The class divStyle include the property
.divStyle
{
height: 435px;
overflow: auto;
}
Oopppzz!!!!!!!

Hi to All,
i have 1 problem, i want to implement captcha control in asp.net,i have searched on google also but not found any helpful result.
can anyone tell me how can i use captcha control in login page
Thank you.

captcha is never used in login that I've seen. Certainly the built in controls do not offer that ability. There are commercial CAPTCHA libraries, if you don't want to write your own. You will probably need to roll your own login code, also, and not use the built in stuff.

The best way to do this, IMO, is to put a transparent div over the whole screen, then position your content inside it. That way, the div gets the clicks. In fact, I suspect that's the only way. That's how the ASP.NET AJAX controls do it AFAIK.

No, it turns out that it's not urgent at all. At least, not for me.
Why do you need to run this exe to generate images ? Where do the images get generated ? How does the exe get run ?

res = new RemoteExecuteServer();
res.opt = "^^" + mProjectName + "^^" + mGraphName;
res.serverPath = Server.MapPath("APAMonitor_CL.exe");
res.Run();
now we run new thread like
public class RemoteExecuteServer : MarshalByRefObject
{
Process myProcess;
public String opt, serverPath, PID;
public void Run()
{
myProcess = new Process();
//ProcessStartInfo info = new ProcessStartInfo(path);
myProcess.StartInfo.FileName = serverPath;
myProcess.StartInfo.Arguments = opt;
myProcess.StartInfo.RedirectStandardInput = false;
myProcess.StartInfo.RedirectStandardOutput = true;
myProcess.StartInfo.WorkingDirectory = serverPath.Replace("APAMonitor_CL.exe", "");
myProcess.StartInfo.CreateNoWindow = true;
myProcess.StartInfo.UseShellExecute = false;
myProcess.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
myProcess.Start();
PID = Convert.ToString(myProcess.Id);
myProcess.WaitForExit();
}
public void ClosePro()
{
myProcess.Close();
}
}
the same thing is working on localhost but not working on clientside
is there any authentication problem on client side.......

Well, there are many questions here.
1 - how do you use these image, once they've been created on the server ?
2 - what happens if more than one person is using the site at the same time ?
3 - how does the user get to see these images, it's surely on a later page to the one they are viewing ?

aftere generating images we are attaching the images to image control.
and then show to the user.but on running the exe the images are not generating at all at server in the specified folder.i m thinking that any pemission is needed which is not available.
|
|
|
|
|
OK, the whole thing sounds messy to me. Certainly your code is more than a little dodgy, IMO. However, overall, if the images are not there, then yes, it's bound to be a permissions issue. Why do you need to spawn a seperate process, why can't you just have the code run inside your web app ?

with the current situation wt are my options .
may i get any help on permission issues.any idea will be apprecialble.
|
|

Do you own the server ? If not, you're out of luck. What you're doing, seems dumb to me. Like I said, if you need to process images, import the code into your web app. I assume you own the server tho, if you can watch the app running. So, write some debug code to work out what is going wrong, I'd guess it's going to be folder permissions.
