I'm not 100% sure about .Net - but I do't think using a 'simple' property uses more processing than using a public variable.
However, a property is more future-prof. if you decide to make a change, and incorporate logic into your getter or setter - it's easer if you already have a getter and setter than if you have a public field. If you're using reflection, you would have to change code to change from a field to a property - and if you mix properties and fields, it can be confusing (as its not obvious which youare using, and using reflection, say to loop over the properties, will miss the fields.
I never use public fields.
The reason being, I see no real advantage of a public field over a simple public property (other than it is less typing - but I don't count that as maintenance is far more expensive than typing time), but sometimes there is advantage to using a property over a public field. Therefore, my standard is to use a property rather than a public field - always. Therefore my fields are always private (or protected) and I know that any access to them is either within that class or a derivative,or via the property.

I have a mystery that I can't figure out. We have a winform application that runs every five minutes as a scheduled job.
On Friday the scheduled task got hung and no one knew it for 24 hours. This application has been working for years. All of the code is in a try catch block that should handle any exception and send an email if an error occurs. On Friday the application simply got stuck...
The only information I have is from the event viewer is the following. How can track down the cause of this error? Is there any way to figure out what line of .net code is at the "reference memory"?
Event Type: Information
Event Source: Application Popup
Event Category: None
Event ID: 26
Date: 2/13/2009
Time: 11:25:04 AM
User: N/A
Computer: myServer
Description:
Application popup: myApp.exe - Application Error : The instruction at "0x7c82caa2" referenced memory at "0x00000000". The memory could not be "read".
I didn't get any requirements for the signature

Hi,
yes it is. you could use the WebBrowser control to display websites or HttpClient to get the content of a page at a lower level.

If you have the application, you can get the answer by running this window application.
On a serious note, try using WebBrowser control.
The word "politics" describes the process so well: "Poli" in Latin meaning "many" and "tics" meaning "bloodsucking creatures."

If you want to display the website on your application, WebBrowser control will help. If you need to download the content of web page, use methods provided in WebClient class.

Hi,
I have a C# program that will start another external program (such as notepad). The C# program needs to pass arguments and the working directory to the external program. I have attempted to do this like:
Process process = new Process();
try
{
process.StartInfo.UseShellExecute = false;
process.StartInfo.FileName = @"c:\Windows\notepad.exe";
process.StartInfo.Arguments = @"c:\test.txt";
process.StartInfo.WorkingDirectory = @"c:\temp";
process.Start();
process.WaitForExit();
}
catch
{
MessageBox.Show("Error running " + strExe, "Error", MessageBoxButtons.OK);
}
Notepad does start and opens the correct file, but the Working Directory has not been set.
I have tried setting the current directory of the C# applicaiton, then running the notepad process, but the Working Directory is still not set.
Please help!
Pete

How do you know this isn't working?
How do you know what Notepad is receiving for its working directory? Its file open/save dialogs remember the last directory you used.
|
|
|
|
|
I've found out that it does work after all. I started a batch file that printed the current directory and ran this from the process and it did print the Working Directory!!!
I've spent ages trying to get it working with Notepad and kept trying the File/Save As... to see if the folder was the Working Directory. I didn't realise that it was always the last one used.

Sir,
I have created a setup of windows application. It works fine now if I want to change the installer manufacturer, author etc I have to do to the original code. Is there some way that I develop an application in which I load the installer and change its properties and save it with new properties. Or during installation I should be given to change the properties.
Looking forward for your reply.
Thank You.

Hi,
I think for this you have to implement an ocr-application. This is a really hard issue, which was solved by several components (all really expensive).
Maybe you should try something different

First you already asked this question and got your answer, the answer isn't going to change because you ask it twice.
Second did you even bother to read the reply from 'williamnw' on your other question? I'd advice you to take his advice.

You asked the same question a few hours ago, and got the same answer then - You can't just open an image like a text file, and read the text out of it - you need to use OCR software, which isn't straightforward or simple.
Maybe this will help[^]
