Is it really possible to start a program that resides in the server from a web application?
I am using following code:
<br />
using System.Diagnostics;<br />
<br />
Process startNotepad = new Process();<br />
startNotepad.StartInfo.FileName = "notepad.exe";<br />
<br />
startNotepad.StartInfo.UseShellExecute = true;<br />
startNotepad.StartInfo.CreateNoWindow = false;<br />
<br />
startNotepad.Start();
This works while debugging the page. I can see notepad start. But when I try it in a server I dont see Notepad, but I do see a process in task manager started

The owner the process started from your web application is ASPNET. ASPNET does not have an active desktop, thus, the process will run but will not display.

Does that mean I could run an application (.exe) in the background (say one without a user interface) that I upload to my server using this method? Say, for example, one that sends out emails to a list I upload... How about one that wipes the server hard-disk.. eek...

If ASPNET's access is more than its default access, you are opening up your web server to some nasty security issues. There are more secure ways of doing running a process.

is it possible to make aspnet has the rights then?

It is possible but not advisable.

I guess it has to be a security issue, am I right?

Yes, it can be a security issue. Also, you loose a lot of control of your application since you are running mulitple processes. Since your web application may have several user using your application at the same time, running several of the same local processes can be come a resource hog or cause some unforeseen conflicts. If a local process fails, how do you recover?

And if i pen the same website on other system with resoltuion of system set to 1024 then my website should get automatically adjusted to that resolution.

You can get the system display settings by using screen.width and screen.height, although I'm not sure if that's what you need.
There's also screen.availWidth and screen.availHeight, which are the available width and height.

Hi ,
I have developed an application wherein the user can upload his photo in a div. The photo is automatically checked and stored using AJAX. I want the user should not be able to do anything else while uploading.Hence i want to gray out all the elements on that page. I thought it would be foolish to disable each item on the page. Is there any method to disable all items on that page all at once?
When you fail to plan, you are planning to fail.

You need to give ASPNET NTFS write priviledges. The default is only read. Also, you will have multiple accesses of that file. Thus, you may need to use the cache.

Hi Guys,
I have a doubt on the working of update panel control. I remember reading that even though it allows partial page update behind the scenes its does a full post back.Or will it be sending and recieving only a part of it.
Thanks in advance for your advice

Check out this page in ie, then check it out in fire fox or safari. This is valid XHTML 1.0.

There is a div that displays when you hover over "Espanol".
Why does the div display at the far left of the next line in mozilla and just below the text (Espanol) in IE?
I want it to show up just under the text, espanol. How can I get it to do that?
Thanks in advance.

Which part of that article are you suggesting applies to my position:absolute issue? In scanning the article I didn't see anything relavent.
|

You need to figure this one on your own since the solution may affect other parts of the page or code added in the future. Also, each version of IE has its own set of bugs. Here is a link that covers a lot of IE bugs with fixes\hacks:

That is strange advice for a message board... The problem is that I cannot figure this one out on my own. Hence the posting of the question here. No one else seems to know the answer either so I don't feel too bad. Perhaps I will just remove the pop up div.

I am sorry for the strange advice. However, making pages consistent on different web browsers is difficult once you start getting a little fancy. Since I don't have mozilla installed, and I don't have the time actually fix your web page, I referred you the aforementioned web pages. By the way, I have also found this website helpful: http://www.alistapart.com/[^].

SOLUTION:
--------------------
Use ul for the absolute positioned content instead of the just a div.
The box models are still inconsistant between browsers with absolute positioned DIVs.
You can still wrap the ul in a wrapper div that has a set width and is positioned absolute so that the ul doesn't get pushed left and down to the next line.
------------------
css:
<code>
#esp_wrapper{
width:250px;
position:absolute;
display:inline;
}
.sd{
margin ;
position:absolute;
background-color:#efefef;
padding:6px;
padding-left:5px;
border:1px #bbb solid;
margin-top:15px;
margin-left:6px;
}
</code>
html:
<code><ul>
<li><a href="#">PDS</a></li>
<li><a href="#">Spec</a></li>
<li><a href="#">MSDS</a></li>
<li class="sd_drop" onmouseover="showHide('sd1', 'block');" onmouseout="showHide('sd1', 'none');">
<div id="esp_wrapper">
<a href="#">Español</a>
<br />
<ul class="sd" id="sd1">
<li><a href="#">PDS</a><br /></li>
<li><a href="#">MSDS</a></li>
</ul>
</div>
</li>
</ul>
</code>

Hi i am developing a web app using asp.net and c#, on a page i have 2 cols of dropdown lists the left filled with player names and right filled with possible heights. when a player is selected theres a postback to find and select the appropriate height for the selected player but the problem is there are 14 players ddls and 14 heights ddls all linked to the same function.
but the problem is if no height is available for the selected player then N/A is selected in the heights ddl and the user can then choose the correct date from the ddl available but when i try to save the players details to the database the event to find the correct height is fired and then players height is reset to N/A... if anyone has an ideas or suggestions i would really appreciate them thanks in advance
Tim
private void player_SelectedIndexChanged(object sender, System.EventArgs e)
{
DropDownList ddlPlayer = sender as DropDownList;
string number = ddlPlayer.ID.Substring(ddlPlayer.ID.IndexOf("homeName")+8);
//*** create person object for height details
DAL.ObjectAccess.Person oPerson = new DAL.ObjectAccess.Person();
oPerson.ID = new SqlInt32(Convert.ToInt32(ddlPlayer.SelectedValue.Substring(0, ddlPlayer.SelectedValue.LastIndexOf(":"))));
oPerson.SelectOne();
//*** select correct height from ddl
DropDownList ddlHeight = (DropDownList)this.FindControl("height" + number);
if(ddlHeight != null)
{
ddlHeight.SelectedValue = oPerson.Height.Value.ToString();
}
//*** display age on label
Label lblAge = (Label)this.FindControl("homeSquad" + number);
if(lblAge != null)
{
lblAge.Text = ddlPlayer.SelectedValue.Substring(ddlPlayer.SelectedValue.LastIndexOf(":")+1);
}
}

Hi,
I am getting the following error:
Microsoft OLE DB Provider for ODBC Drivers (0x80004005)
[Microsoft][ODBC Microsoft Access Driver] Operation must use an updateable query.
I know that I need to set permissions on the Access database but can not remember how. Normally I would right click, and click on properties, and select the users and set the permissions, but I reloaded my machine and I can not see those options there.
Please can someone help. I am using classic ASP and Access.
Thanks
