I can't think of any more hints, those are the ones I would have given also.

You could try recommending a book, not the one that book stores want you to buy thou

Nah. I only do that when a very basic question is getting asked; anyway, feel free to visit a decent book store, I could recommend the Stanford University Bookstore on the Palo Alto campus, it is quite impressive (I think it looks like an Amazon warehouse).
FYI: I added a book thread[^] on my personal CP blog for your convenience.

That's a bit far for me, but thanks none the less. I went to a book store the other day and could not even find a computer section! I'll try a different one next time...
Some good advise in your thread

Same here, but I do visit it on every opportunity, which is once in ten years or so.

I love when they post code that is a disaster, we try to help, and they never answer anyone who replies.

I know 
I think in all the answers I gave to questions (which is compared to you almost nothing but hey I try ) I might have gotten an answer back like twice or so.

Smart people walk away from disasters, for some reason we feel attracted to them??

It's the same as seeing an accident on the road.
For some reason you can't resist to look.

Hi All,
I have to develop an application using C#. Application requirements is given below:
1.Automatically send job alerts to all the registered job seekers based on some criteria like
work experience,Skills etc.
2.There are about 9 lac registered users and will increase in future.
3.Once the application started will send email to all the users and after completing the
email sending to all users it will stop/pause for some time say 3 hours and after that
it will automatically started . This process will keep on repeating until administrator
stop the application.
4.Application will run on the same server where database is running.
Please suggest me how to develop the application so that it consume minimum resources of the server?
Should I develop an application or a windows service? Which will be the best solution?
Please give suggestion keeping in mind that server resources should be consumed minimum?
Please Help.
Thanks & Regards,
Dev

No, I wont do that.
I'll need to keep polling for checking when to start the next batch as he wants to do this every 3 hrs.

You're asking for the source code to your project ? How about you buy some books, or use google, or even search this site for articles ?

You could create a Console Application which can be scheduled to run after every 3 hours. Admin may disable the task if he wants.
You need to come up with a logic which will get the users to whom you want send the email. This will be a stored procedure returing you the user details and probably also the email content.

1)I don't want to run this application after every 3 hours. I want that application stop/pause for 3 hours after sending emails to all users and after that it starts automatically.
2) Its not necessary that it take same time to send emails to all users. Time to complete the process by the application may change as it depends on availability of system resources and on some others factors too.
Thanks,

Hi,
When trying to run a vb script on a machine, this is what it gives as error:
Can't find script engine \"VBScript\"
So to fix this I logged into the machine and did the following to install the vbscript engine:
in run window
regsvr32 vbscript
Message was that installation succeeded.
Then tried running the script on the machine again and still gives the same error as before.
Any thoughts please?
Thanks

I want to store images in text form and later load them again.
I got this code to convert and image to a base64 string:
ImageConverter converter = new ImageConverter();
byte[] raw = new byte[1];
Bitmap test = new Bitmap(OFD_Open.FileName);
raw = (byte[])converter.ConvertTo(test, typeof(byte[]));
string output = Convert.ToBase64String(raw);
File.WriteAllText("image.txt", output);And this code to convert it from a string back to an image
byte[] raw = new byte[1];
Bitmap pic = new Bitmap(1, 1);
raw = Convert.FromBase64String(OFD_Open.FileName);
PictureBox box = new PictureBox();
TypeConverter tc = TypeDescriptor.GetConverter(typeof(Bitmap));
pic = (Bitmap)tc.ConvertFrom(raw); But the Convert.FromBase64String method throws an error, telling me there is an invalid character in the Base64 string.
What went wrong?
Thanks.

Hi,
the Convert.FromBase64String expect a base64-encoded string, which is in your case stored within a file. But you pass the name of the file. You have to pass the content of the file!

I think converting the filename won't help much...
If I were you I would convert the content!
From the top of my mind perhaps this will work:
Convert.FromBase64String(File.ReallAllText(OFD_Open.FileName));
A train station is where the train stops. A bus station is where the bus stops. On my desk, I have a work station....
