The sender argument ( the one that's an object ) is a reference to the control that generated the event. You can check if it's a particular textbox directly, or cast it and then use the tag or name properties.

Guys
One more thing just occured to me. Is it possible to get the value contained within the textbox from the object sender? I have the name of the textbox by querying the sender object, but can I also get teh value contained within that textbox by similar means. I cant see anything obvious like .value for instance
Many thanks
Colin

Oh yes. It's also very handy. Of course you have to identify the control that generated the event by inspecting the sender argument of the event handler.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Plzz tell me how can i get these records and place in a table having 12 columns(one column for each above column)

Do you want C# code to do this?
If not you can use import option in the Access.

yes I want C# code. or some idea that how can i do this.

Microsoft offer Office interop libraries so you can call excel. Passing data into Access is trivial and well documented on the web.

Hi.
Do you have any idea of how could the path to the exe file of an installed application(like MS Words or Adobe Reader) be found?
Thanks.

If it has a file type associated with it ( like doc or pdf ), then you can find it in the registry. That's how windows knows how to open a file when you double click on it.

Hi,
This is my first post, so please excuse my poor english or if I miss giving you important info.
I need to start a windowless exe file from an internal website. I have been using System.Diagnostics.Process with credentiels and without. If I use it with credentiels I get a "The application failed to initialize properly (0xc0000142)." error and without I get different sort of errors from the application I am trying to start.
The exe I want to start is written in C# (as is the website), and I have the sourcecode for the exe.
The website and the exe file is running on the same machine (a 2003 server). The exe is also running every night by a scheduled task. I have been trying to start the scheduled task aswell, but hit a dead rock there aswell...
Does anyone have a good formula for doing this? As this is on an internal website the security issues are less crusial (but still important).
Best Regards
Caroline

Statistically, most computer crime is an inside job. Therefore, logically, more emphasis should be put on security for internal applications. But that rarely happens.
Caroline Ledin wrote: I get different sort of errors from the application I am trying to start.
What is the error?
Also, remember that if you start the process from the web application you will be using the same credentials as the web application, usually the ASPNET account. Could it be that the application requires more rights to operate than the ASPNET account permits?

Are there any error messages from that scenario?

The error's I get from the application is
1.System.Security.SecurityException: That assembly does not allow partially trusted callers
When I got this error, I added the ASP-user to the security tab of the exe file.
After that I got the next error message:
2.An unhandled exception ('System.IO.FileLoadException') occurred in BankService.exe
And I was stuck again...
When I run the Scheduler task option I did the following
exeProcess.StartInfo.FileName = "schtask";
exeProcess.StartInfo.Arguments ="/run /tn BankService";
and
exeProcess.StartInfo.FileName = "cmd";
exeProcess.StartInfo.Arguments ="schtask /run /tn BankService";
It didnt do anything...
I checked the scheduler and nothing had happened and I checked the Task manager and no process with the bankservice had started.
The exe im trying to start I have stripped from doing anything but Console.WriteLine and EventLog.WriteEntry.
In the webconfig file it is added (not due to this)
<identity impersonate="true" userName="xxxx" password="yyyy"/>
How do I set the asp net user to access the desktop or can I get the process to run as antoher user but the net user?. The website requires you to log in with your windows credentiels...

Sounds like what you need to do is write it as a service, I'm pretty sure you can set up a service to be called from an ASP.NET app.

if that is a .net exe then add it in GAC. with "gacutil -i exe_path"
then give full trust to it with "caspol -af exe_path" use sdk command prompt.
Add this in webconfig.
<identity impersonate="true"/>
try ur program after that.

sorry for the late reply, but had to try/fix a few things to get it all working.
I have installed the exe with the gacutil tool and had to strong name type it first...
Then when I try the caspol command I get an error
Usage: caspol <option> <args> ...
any suggestions on this error?
I hate to be forced to make a service out of this....
Thanks for the help by the way

Made the service and is stuck on yet another access denied problem...
When I try to start the service
myControl = new ServiceController("StartSchTask");
String[] args;
args = new String[2];
args[0] = "BankService";
args[1] = "cl@ikaros.se";
myControl.Start(args);
I get the "Cannot start service StartSchTask on computer '.'." error and I believe that this is an access denied error....
any suggestions...*banging head into the wall...*
